These four nozzle rows are arranged such that their positions in the X direction are shifted from each other so that the positions of the nozzles N1 in the X direction do not overlap. Note that the number of nozzle rows that the warp discharge head 312 has is not limited to four, and may be three or less or five or more. Further, the nozzle rows may be arranged in a direction oblique to the X direction.

The ejection mechanism for ejecting the warp ink from the nozzle N1 is not particularly limited, but for example, a pressure chamber communicating with the nozzle N1 is provided inside the piezoelectric body, and a shear mode displacement is applied to the piezoelectric body on the wall surface of the pressure chamber. It is possible to use a shear mode ejection mechanism that ejects ink from the nozzle N1 by causing pressure fluctuations in the ink within the pressure chamber.

The eight warp discharge heads 312 in the upstream warp head unit 31a are arranged in a houndstooth pattern so that the arrangement range of the nozzle N1 in the X direction is continuous, forming a line head. The arrangement range in the X direction of the nozzle N1 included in the upstream warp head unit 31a covers the fabric forming range R1 (FIG. 1) in the X direction on the discharge target surface 21a. Therefore, the upstream warp head unit 31a is provided so as to be able to eject the warp ink over the fabric forming range R1. The upstream warp head unit 31a is used with a fixed position when discharging the warp ink, and the warp ink is ejected from the nozzle N1 to each position at a predetermined interval in the moving direction according to the movement of the discharge target surface 21a. By discharging the warp ink, the warp ink is discharged onto the discharge target surface 21a in a single pass manner.

In this embodiment, a thermosetting ink that is cured by heat is used as the warp ink. The direction in which the ink is cured by heat corresponds to the first curing method. Further, as the warp ink, one that has a certain degree of elasticity and flexibility even after being cured by heat is used. Therefore, "curing" of the ink in this specification includes a mode in which the ink is thickened to the extent that it has elasticity and flexibility.
The discharge target surface 21a of the conveyor belt 21 is heated to a predetermined temperature by a conveyor belt heating section 71 (see FIG. 5). For this reason, the warp ink ejected from the warp ejection head 312 is heated and somewhat thickened when it lands, and does not wet and spread along the ejected surface 21a, but forms a shape that swells to some extent from the ejected surface 21a. maintain. The heating temperature by the conveyor belt heating section 71 is set to a temperature near the lower limit of the temperature range that can suppress the landed warp ink from getting wet and spreading. Therefore, the warp ink that has landed on the ejection target surface 21a is not completely cured at the time of landing.

Although the specific composition of the warp ink is not particularly limited, for example, one containing a thermally polymerizable compound (monomer), a thermal polymerization initiator, and a colorant can be used. Among these, the thermally polymerizable compound is a compound that undergoes a polymerization reaction and becomes a polymer when exposed to a standard amount of heat or more. This polymerization increases the viscosity of the ink and hardens it. The thermal polymerization initiator is a compound for starting the above polymerization reaction. Colorants include pigments or dyes of the color associated with the ink.
Further, at least a portion of the composition is a hydrophobic resin. Therefore, the warp ink is one in which a hydrophobic resin is dispersed in a dispersion medium.

A warp temporary curing section 41 is provided downstream of the upstream warp head unit 31a in the moving direction of the discharged surface 21a. The warp temporary curing section 41 has a heater that heats the discharge target surface 21a in a width range including the fabric forming range R1 in the X direction. The warp temporary curing section 41 uses this heater to heat the warp ink that has been ejected from the upstream warp head unit 31a and landed on the ejection target surface 21a, thereby temporarily curing the warp ink. Temporary curing here refers to allowing the curing reaction (the above-mentioned polymerization reaction) of the warp ink to proceed and stopping it at a stage before the curing reaction is completed. Therefore, even after temporary curing by the warp temporary curing section 41, the warp ink is not completely cured. The warp ink that has been temporarily cured by the warp temporary curing section 41 has an increased viscosity compared to the state immediately after landing, making it easier to maintain its shape.
Note that if the warp ink can be temporarily cured to a desired state by heating the discharge target surface 21a by the conveyor belt heating section 71, the warp temporary curing section 41 may be omitted.

The downstream side of the warp temporary hardening section 41 in the moving direction of the discharge target surface 21a is a moving range of the carriage 60.
The weft head unit 32 mounted on the carriage 60 performs a second ejection operation to eject weft ink (second material). As shown in FIG. 1, the weft head unit 32 includes a plurality of (here, four) weft discharge heads 322. Each weft discharge head 322 moves in the X direction together with the carriage 60 and discharges the weft ink to the discharge target surface 21a at an appropriate timing based on the weft pattern data 142 (see FIG. 5), thereby curing the weft ink. Weft ink is landed at a position that will later become a weft (second thread) of the fabric 90. The weft ink is ejected from the upstream warp head unit 31 a to a position overlapping a portion of the warp ink that has been temporarily cured by the warp temporary curing section 41 . The warp ejection head 312 is arranged so that the warp ink is ejected vertically downward.

FIG. 4 is a schematic diagram showing the configuration of the weft head unit 32, and is a plan view of the weft head unit 32 viewed from the side facing the discharged surface 21a of the conveyor belt 21.
The weft head unit 32 includes a plate-shaped support portion 321 and a plurality of (four in this case) weft discharge heads 322 fixed to the support portion 321 in a state that is engaged with a through hole provided in the support portion 321. and has. The weft discharge head 322 is fixed to the support part 321 with the ink discharge surface provided with the opening of the nozzle N2 (second nozzle) exposed from the through hole of the support part 321 toward the conveyor belt 21 side. ing.

The weft discharge head 322 has four nozzle rows similarly to the warp discharge head 312. However, the number of nozzle rows that the weft discharge head 322 has is not limited to four, and may be three or less or five or more. Further, the nozzle rows may be arranged in a direction oblique to the Y direction. As the weft ink ejection mechanism in the weft ejection head 322, for example, a vent mode ejection mechanism like the warp ejection head 312 can be used.

The four weft discharge heads 322 in the weft head unit 32 are arranged in a houndstooth pattern so that the arrangement range of the nozzle N2 in the Y direction is continuous, thereby forming a line head. The arrangement range in the Y direction of the nozzle N2 included in the weft head unit 32 covers the weft discharge range R2 (discharge range) (FIG. 1) in the Y direction on the discharge target surface 21a. Therefore, the weft head unit 32 can cause the weft ink to land in the weft discharge range R2 every time the carriage 60 moves (scans) in the X direction once.

As the weft ink, a photocurable ink that is cured by light can be used. The direction in which the ink is cured by light corresponds to the second curing method. Here, in addition to visible light, light includes energy rays having wavelengths that are not included in the wavelength range of visible light, such as ultraviolet rays and infrared rays. In this embodiment, an ultraviolet curable ink that is cured by ultraviolet rays is used as the weft ink. In addition, as the weft ink, one that has a certain degree of elasticity and flexibility even after being cured by ultraviolet rays is used.
Further, the weft ink is a phase change ink whose phase changes between a gel state and a sol state depending on the temperature. The weft head unit 32 includes an ink heating section (not shown), and weft ink heated by the ink heating section and turned into a sol is ejected from the nozzle N2 of the weft discharge head 322. The temperature of the weft ink that has landed on the ejection target surface 21a decreases and quickly becomes gel-like. As a result, the weft ink after landing does not wet and spread along the ejection target surface 21a, but maintains a shape that swells to some extent from the ejection target surface 21a.

The specific composition of the weft ink is not particularly limited, but for example, one containing a photopolymerizable compound (monomer), a photopolymerization initiator, a gelling agent, and a colorant can be used. Among these, the photopolymerizable compound is a compound that undergoes a polymerization reaction and becomes a polymer when irradiated with ultraviolet rays. This polymerization increases the viscosity of the ink and hardens it. A photopolymerization initiator is a compound for starting the above polymerization reaction. The gelling agent dissolves in the ink and turns the ink into a sol when the ink is heated to a temperature higher than the solization temperature, and when the ink is cooled to a temperature lower than the gelation temperature, it forms a crosslinked structure or forms a fibrous aggregate. It is a compound that has the property of causing ink to gel by forming an ink. Moreover, the coloring agent includes a pigment or dye of the color related to the ink.
Furthermore, at least a portion of the composition is a hydrophilic resin. Therefore, the weft ink has a hydrophilic resin dispersed in a dispersion medium, and has a different composition (material) from the warp ink containing a hydrophobic resin. This prevents the weft ink that has landed at a position overlapping the warp ink on the ejection target surface 21a from coalescing with the warp ink.

A weft curing section 42 is mounted on the carriage 60 at a position adjacent to the weft head unit 32 in the X direction. Two weft hardening sections 42 are provided, one each on both sides of the weft head unit 32 in the X direction. The weft curing section 42 irradiates the discharge target surface 21a with ultraviolet rays in a range including the weft discharge range R2 in the Y direction while moving in the X direction together with the carriage 60. Thereby, the weft curing section 42 cures the weft ink that has been discharged from the weft head unit 32 and landed on the discharge target surface 21a. Specifically, when the carriage 60 is moving in the +X direction, the weft ink discharged from the weft head unit 32 is irradiated from the weft curing section 42 on the -X direction side of the weft head unit 32. It is cured by ultraviolet rays immediately after impact. Furthermore, when the carriage 60 is moving in the -X direction, the weft ink discharged from the weft head unit 32 is exposed to ultraviolet rays irradiated from the weft curing section 42 on the +X direction side of the weft head unit 32. As a result, it hardens immediately after impact. When the carriage 60 moves, ultraviolet rays may be irradiated from the two weft curing sections 42, or ultraviolet rays may be irradiated only from the weft curing section 42 on the downstream side in the moving direction of the carriage 60.
The weft ink cured by the weft curing section 42 becomes the weft T2 of the fabric 90.

A downstream warp head unit 31b is provided downstream of the weft discharge range R2 in the moving direction of the discharged surface 21a. The downstream warp head unit 31b performs a first ejection operation of ejecting warp ink (first material) similarly to the upstream warp head unit 31a. The configuration of the downstream warp head unit 31b and the composition of the warp ink to be ejected are the same as the configuration of the upstream warp head unit 31a, so a detailed explanation will be omitted. Note that FIG. 3 described above is also a plan view of the downstream warp head unit 31b viewed from the side facing the discharge target surface 21a.

The downstream warp head unit 31b discharges warp ink at an appropriate timing based on the warp pattern data 141 to the moving ejecting surface 21a, thereby ink warp ink that has already landed on the ejecting surface 21a. The warp ink is made to land at a position that partially overlaps the ink and the weft ink. Specifically, the downstream warp head unit 31b selects a portion where the warp ink discharged from the upstream warp head unit 31a has not landed among the positions that will become the warp T1 (see FIG. 8) of the fabric 90 after curing. The warp ink is ejected and landed at the position where it is filled.
Since the weft ink on the discharge target surface 21a contains a hydrophilic resin, the warp ink discharged by the downstream warp head unit 31b does not combine with the weft ink. On the other hand, the warp ink that has been ejected by the upstream warp head unit 31a and has already landed has been temporarily cured by the warp temporary curing section 41 and has not been completely cured. The warp ink discharged by the side warp head unit 31b is discharged by the upstream warp head unit 31a and merges with the already landed warp ink.

The warp hardening section 43 is provided on the downstream side of the downstream warp head unit 31b with respect to the moving direction of the discharge target surface 21a. The warp curing section 43, like the warp temporary curing section 41, has a heater that heats the discharge target surface 21a in a width range including the fabric forming range R1 in the X direction. The warp temporary curing section 41 uses this heater to heat the warp ink that has been discharged from the upstream warp head unit 31a and the downstream warp head unit 31b and landed on the discharged surface 21a, thereby curing the warp ink. let The cured warp ink forms the warp of the fabric 90. Therefore, at the stage when the curing of the warp ink by the warp curing section 43 is completed, the fabric 90 in which the warp T1 formed from the warp ink and the weft T2 formed from the weft ink are woven onto the discharge target surface 21a. formed on top.

The fabric 90 that has been conveyed to the rear end of the discharge target surface 21a is peeled off diagonally upward from the discharge target surface 21a and wound up by a winding roller 80 shown in FIG.

FIG. 5 is a block diagram showing the main functional configuration of the inkjet recording apparatus 1. As shown in FIG.
The inkjet recording apparatus 1 includes a control section 10 (control means), a moving section 20 having a belt conveyance section 201 and a carriage moving section 202, an upstream warp head unit 31a, a downstream warp head unit 31b, and a weft head unit 31a. An ink discharge section 30 having a head unit 32, a warp temporary curing section 41, a weft curing section 42, and a warp curing section 40 having a warp curing section 43, a pretreatment section 50, a conveyor belt heating section 71, and an operation display section 72. , a communication section 73, a bus 74, and the like. In the following, description of the components already described will be omitted.

The control unit 10 includes a CPU 11 (Central Processing Unit), a RAM 12 (Random Access Memory), a ROM 13 (Read Only Memory), and a storage unit 14.

The CPU 11 reads out a program 131 and setting data stored in the ROM 13, stores them in the RAM 12, and executes the program 131 to perform various calculation processes.

The RAM 12 provides a working memory space for the CPU 11 and stores temporary data. RAM 12 may include nonvolatile memory.

The ROM 13 stores a program 131 executed by the CPU 11, setting data, and the like. Note that a rewritable nonvolatile memory such as a flash memory may be used instead of the ROM 13.

The storage unit 14 stores a fabric forming job (fabric forming command) input from an external device via the communication unit 73, and image data related to warp pattern data 141 and weft pattern data 142 used in the fabric forming job. Ru. The warp pattern data 141 and the weft pattern data 142 are image data reflecting the weaving pattern of the warp T1 and the weft T2 in the fabric to be formed. The warp pattern data 141 includes pattern data indicating a position at which warp ink is ejected by the upstream warp head unit 31a, and pattern data indicating a position at which warp ink is ejected by the downstream warp head unit 31b. The weft pattern data 142 includes pattern data indicating the position at which weft ink is ejected by the weft head unit 32. As the storage unit 14, for example, an HDD (Hard Disk Drive) is used, and a DRAM (Dynamic Random Access Memory) or the like may also be used in combination.

The control unit 10 having such a configuration centrally controls the entire operation of the inkjet recording apparatus 1 by having the CPU 11 execute predetermined processing according to the program 131.
For example, the control unit 10 sends a control signal to the conveyance drive unit 23 at appropriate timing to operate the conveyance drive unit 23, rotate the conveyance roller 22, and move the conveyance belt 21 around at a predetermined speed.
Further, the control unit 10 causes the carriage moving unit 202 to move the carriage 60 in the X direction at a predetermined speed by sending a control signal to the carriage moving unit 202 at an appropriate timing.
In addition, the control unit 10 sends warp pattern data 141 and control signals to head drive boards (not shown) mounted on the upstream warp head unit 31a and the downstream warp head unit 31b, respectively. A drive signal is outputted from the head drive board to the warp ejection head 312 at an appropriate timing according to the position of the surface 21a, and the warp ink is ejected from the nozzle N1 of the warp ejection head 312.
In addition, the control unit 10 sends the weft pattern data 142 and a control signal to a head drive board (not shown) mounted on the weft head unit 32, thereby driving the head at an appropriate timing according to the position of the carriage 60. A drive signal is outputted from the substrate to the weft discharge head 322, and the weft ink is discharged from the nozzle N2 of the weft discharge head 322.

The operation display unit 72 includes a display device such as a liquid crystal display or an organic EL display, and an input device such as operation keys and a touch panel placed over the screen of the display device. The operation display section 72 displays various information on the display device, and also converts a user's input operation on the input device into an operation signal and outputs it to the control section 10.

The communication unit 73 transmits and receives data to and from external devices according to a predetermined communication standard. The communication unit 73 includes a connection terminal according to the communication standard to be used, driver hardware (for example, a network card) related to the communication connection, and the like.

The bus 74 is a path for transmitting and receiving signals between the control unit 10 and other components.

Next, a method for manufacturing (forming) the fabric 90 using the inkjet recording apparatus 1 will be described.
When the control unit 10 receives the fabric forming job via the communication unit 73, it starts processing for forming the fabric.
First, the control unit 10 causes the conveyor belt heating unit 71, the warp temporary curing unit 41, and the warp curing unit 43 to start heating operations. Further, the control unit 10 causes the weft curing unit 42 to start the ultraviolet ray irradiation operation. Further, the control unit 10 operates the discharge target surface moving unit 24 to start rotating the conveyor belt 21, and causes the pretreatment unit 50 to start applying the release agent.

When the heating temperature by the conveyor belt heating section 71, the warp temporary curing section 41, and the warp curing section 43 falls within the specified temperature range, and the irradiation intensity of ultraviolet rays from the weft curing section 42 falls within the specified intensity range, the control section 10: A dough 90 is formed by performing predetermined discharge control. In this ejection control, the control unit 10 controls the warp ink ejection operation (the first 1 discharge operation), a discharge operation of weft ink by the weft head unit 32 (second discharge operation), a movement operation of the discharge target surface 21a by the discharge target surface moving section 24 (first movement operation), and a carriage The moving operation (second moving operation) of the carriage 60 by the moving unit 202 is controlled. Here, in the above-mentioned predetermined pattern, the warp ink after being cured by the curing section 40 becomes the warp T1 which constitutes the fabric and extends in the Y direction (predetermined direction), and the weft ink after being cured by the curing section 40 becomes the warp T1 which constitutes the fabric and extends in the Y direction (predetermined direction). , is a pattern that extends in a direction intersecting the Y direction (in the present embodiment, the X direction) and becomes the weft thread T2 constituting the fabric 90.

Specifically, the step of forming the dough 90 through discharge control includes the following steps (1) to (4).
(1) A step of discharging the warp ink to form the lower thread-like member t1a which becomes a part of the warp T1 after hardening.
(2) A step of discharging and curing the weft ink over a part of the lower thread-like member t1a to form the weft T2.
(3) A step of discharging the warp ink to form an upper layer thread-like member t1b that becomes a part of the warp T1 after hardening.
(4) A step of hardening the first thread-like member t1 consisting of the lower-layer thread-like member t1a and the upper-layer thread-like member t1b to form the warp threads T1.
Each of the steps (1) to (4) will be described below with reference to FIGS. 6 to 9. 6 to 8 are enlarged plan views illustrating each step of forming the dough 90. 9(a), FIG. 9(b), and FIG. 9(c) are side cross sections taken along line AA in FIG. 6, line BB in FIG. 7, and line CC in FIG. 8, respectively. FIG.

(1) Formation process of lower layer filamentous member FIGS. 6 and 9(a) are diagrams illustrating the formation process of the lower layer filamentous member t1a.
In FIG. 6, a part of the upstream warp head unit 31a, the downstream warp head unit 31b, and the weft head unit 32 are illustrated.
Moreover, the two-dimensional arrangement of the nozzles N1 in the upstream warp head unit 31a and the downstream warp head unit 31b is simplified into a one-dimensional arrangement that reflects only the positional relationship in the X direction. Therefore, the adjacent nozzles N1 in FIG. 6 are actually at different positions in the Y direction.
Similarly, the two-dimensional arrangement of the nozzles N2 in the weft head unit 32 is simplified into a one-dimensional arrangement that reflects only the positions in the Y direction. Therefore, the adjacent nozzles N2 in FIG. 6 are actually at different positions in the X direction.

The control unit 10 causes the upstream warp head unit 31a to cause the warp ink to land at a position that will become part of the warp T1 after hardening while moving the discharge target surface 21a at a predetermined speed. A lower thread-like member t1a is formed on top. The lower thread-like member t1a is a piecemeal line-like member extending in the Y direction. The control unit 10 discharges the warp ink from the nozzle N1 at a timing based on the warp pattern data 141, so that the plurality of lower thread members t1a have a regular positional relationship in the X direction and the Y direction. A lower thread-like member t1a is formed. The positional relationship of the plurality of lower layer thread-like members t1a is determined depending on the weaving method of the fabric 90 to be formed. 6 to 9 illustrate patterns for forming a plain weave fabric 90. In this case, the plurality of lower filamentous members t1a are arranged in a houndstooth pattern.

In FIG. 6, one lower layer thread-like member t1a is formed by the warp ink ejected from one nozzle N1, but the present invention is not limited to this, and one lower layer is formed by two or more nozzles N1 adjacent to each other in the X direction. A thread-like member t1a may also be formed. That is, the control unit 10 may set the number of nozzles N1 used for forming the warp T1 among the plurality of nozzles N1, depending on the thickness of the warp T1 to be formed.

The warp ink that has landed on the discharged surface 21a thickens due to the heat of the conveyor belt 21 heated by the conveyor belt heating section 71, and forms the lower thread-like member t1a without wetting and spreading on the discharged surface 21a. Further, the lower thread-like member t1a is temporarily hardened by passing through the heating range of the warp temporarily hardening section 41 due to the movement of the discharge target surface 21a, and further increases in viscosity.

(2) Step of forming weft threads FIGS. 7 and 9(b) are diagrams illustrating the step of forming weft threads T2.
When the surface to be discharged 21a on which the lower thread-like member t1a is formed moves to the weft discharge range R2, the control unit 10 stops the movement of the surface to be discharged 21a, and then moves the carriage 60 (therefore, the weft head unit 32) The weft ink is ejected by the weft head unit 32 while moving the weft. Specifically, the control unit 10 causes the weft ink to be ejected from the nozzle N2 at a timing corresponding to the weft pattern data 142, so that the weft ink lands at a position overlapping a part of the lower thread-like member t1a, and after curing. A second thread-like member t2, which becomes the weft thread T2, is formed on the discharge target surface 21a. Here, the second thread-like member t2 is formed in a line shape extending along the X direction over the entire fabric forming range R1.

Here, the lower thread-like member t1a is temporarily hardened by the warp temporary hardening section 41 before the weft ink is ejected, so that the shape is not collapsed even if the weft ink lands on the lower thread-like member t1a. It has become. Moreover, since the weft ink becomes gel-like immediately after landing, it forms the second thread-like member t2 without getting wet and spreading on the ejection target surface 21a. Further, since the lower thread-like member t1a contains a hydrophobic resin and the weft ink contains a hydrophilic resin, the discharged weft ink does not coalesce into the lower thread-like member t1a.

In addition, in parallel with the discharge of the weft ink from the weft head unit 32, the weft ink (the second thread-like member t2 immediately after being formed) immediately after landing is cured by ultraviolet irradiation from the weft curing section 42. . Therefore, before the second filament member t2 is entirely formed, the already formed portion is cured by ultraviolet irradiation. In this way, the formation of the second thread-like member t2 and the formation of the weft thread T2 by hardening of the second thread-like member t2 proceed in parallel.
Note that at least one of ink discharge from the weft head unit 32 and ultraviolet irradiation of the weft ink by the weft curing section 42 causes movement of the carriage 60 (movement in the +X direction and/or movement in the -X direction). This may be repeated multiple times.

In FIG. 7, one second filament member t2 and weft T2 are formed by the weft ink discharged from one nozzle N2, but the present invention is not limited to this, and two or more nozzles adjacent to each other in the Y direction N2 may form one second thread-like member t2 and weft thread T2. That is, the control unit 10 may set the number of nozzles N2 used for forming the weft T2 among the plurality of nozzles N2, depending on the thickness of the weft T2 to be formed.

(3) Forming process of upper layer filamentous member FIGS. 8 and 9(c) are diagrams illustrating a forming process of upper layer filamentous member t1b. In FIG. 8, the state of formation of the upper layer thread-like member t1b is depicted in the section from the downstream warp head unit 31b to the warp hardening section 43.
When the weft T2 is formed as shown in FIG. 7, the control unit 10 restarts the movement of the discharge target surface 21a. Then, while moving the discharged surface 21a at a predetermined speed, the control unit 10 sends the warp ink from the downstream warp head unit 31b at a timing when the weft T2 passes through a position facing the downstream warp head unit 31b. to be discharged. Specifically, the control unit 10 causes the warp ink to be ejected from each nozzle N1 at a timing based on the warp pattern data 141, so that the warp ink lands at a position that will become a part of the warp T1 after hardening, and the upper layer thread-like member t1b is formed. Here, the landing position of the warp ink connects two lower layer thread-like members t1a adjacent to each other in the Y direction, and the weft thread T2 (second thread-like member t2 after hardening) is located between the two lower thread-like members t1a. This is a position that overlaps with a part of .
At this time, the lower thread-like member t1a is in a state where it has been temporarily hardened by the warp temporary hardening section 41 and has not been completely hardened, so the warp ink discharged by the downstream warp head unit 31b is It merges with the lower filament member t1a to form a continuous state. Moreover, since the weft thread T2 has already been hardened, the discharged warp ink does not coalesce with the weft thread T2.

As a result, as shown on the right side of FIG. 9(c), in the CC cross section perpendicular to the The thread-like member t1b is united to form a single connection. As a result, the first thread-like member t1, which is composed of the lower-layer thread-like member t1a and the upper-layer thread-like member t1b and becomes the warp thread T1 after hardening, is formed.

(4) Warp formation process In parallel with the formation of the first thread-like member t1, when the already formed first thread-like member t1 passes through the heating range by the warp hardening section 43 due to the movement of the discharge target surface 21a, the first thread-like member t1 The portion of the thread-like member t1 that has passed through the heating range is hardened and becomes the warp thread T1.
In FIGS. 8 and 9(c), a portion where the warp threads T1 are formed is drawn in a range downstream from the warp hardening section 43 in the moving direction of the discharge target surface 21a.
As shown in FIG. 9(c), during curing by heating, the lower thread-like member t1a and the upper thread-like member t1b attract each other at the contact point, and are cured in a state in which they are connected in a smoother shape than before curing. As a result, the warp threads T1 that form the fabric 90 are formed.

In a state where the warp threads T1 are formed by hardening the first thread-like member t1, a fabric 90 in which the warp threads T1 and the weft threads T2 are woven is formed on the discharge target surface 21a. In the fabric 90, the warp threads T1 and the weft threads T2 are not unified, but are independent threads. Therefore, a fabric 90 having a feel and texture similar to that of a fabric woven from plant fibers or the like can be obtained.
In addition, in the above explanation, each process (1) to (4) was explained focusing only on a specific part of the fabric 90, but in parallel with these, each process for other parts of the fabric 90 is explained. This is performed sequentially in accordance with the movement of the ejection target surface 21a. Therefore, a dough 90 connected in the Y direction is formed on the ejection target surface 21a, and the formed dough 90 is sequentially wound up by the winding roller 80.

(Modification 1)
Next, a first modification of the above embodiment will be described. This modification differs from the above embodiment in that it is possible to form a fabric 90 having warp threads T1 and weft threads T2 colored in a desired color. Below, differences between the above embodiments will be explained, and explanations of common points with the above embodiments will be omitted.

FIG. 10 is a plan view showing a schematic configuration of an inkjet recording apparatus 1 according to a first modification.
The inkjet recording apparatus 1 of this modification includes a plurality of upstream warp head units 31a, a plurality of downstream warp head units 31b, and a plurality of weft head units 32 that eject inks of different colors.
Between the pre-processing section 50 and the warp temporary curing section 41, cyan (C), magenta (M), yellow (Y), and black (K) warps are arranged in order from the upstream side in the moving direction of the discharge target surface 21a. The upstream warp head units 31Ca, 31Ma, 31Ya, and 31Ka, which respectively eject the ink, are arranged at predetermined intervals.
In addition, C, M, Y, and K warp inks are ejected onto the downstream side of the movement range of the carriage 60 and the upstream side of the warp curing section 43 in order from the upstream side in the moving direction of the ejected surface 21a. The side warp head units 31Cb, 31Mb, 31Yb, and 31Kb are arranged at predetermined intervals.
In addition, the carriage 60 has weft head units 32C, 32M, 32Y, and 32K arranged at predetermined intervals between the two weft curing sections 42 and discharging C, M, Y, and K weft inks, respectively. are arranged in
Note that the number of each head unit, that is, the number of colors of ink to be ejected may be three or less or five or more.

In the inkjet recording apparatus 1 having this configuration, the warp head unit group 31 (first ejection means) consisting of the plurality of upstream warp head units 31a and the plurality of downstream warp head units 31b is configured to eject a plurality of different colors. It is provided to be able to eject warp ink, and the plurality of weft head units 32 (second ejection means) are provided to be able to eject weft ink of a plurality of different colors.
Therefore, by appropriately selecting the head unit (that is, the color of the ink to be ejected) for ejecting ink to each position on the ejection target surface 21a from among four colors, the warp threads T1 and weft threads are colored in a desired color. T2 can be formed. Therefore, the fabric 90 can be formed with a pattern or image of a desired color formed thereon. In order to form the colored fabric 90 in this way, warp pattern data 141 and weft pattern data 142 corresponding to each color of C, M, Y, and K are prepared, and each head unit selects warp threads of the corresponding color. The discharge operation may be performed based on the pattern data 141 or the weft pattern data 142.

(Modification 2)
Next, a second modification of the above embodiment will be described. This modification differs from the above embodiment in that both a warp head unit 31 and a weft head unit 32 that eject ink are mounted on a carriage 60. This modification may be combined with modification 1 above. Below, differences between the above embodiments will be explained, and explanations of common points with the above embodiments will be omitted.

FIG. 11 is a plan view showing a schematic configuration of an inkjet recording apparatus 1 according to a second modification.
In the inkjet recording apparatus 1 of this modification, a warp head unit 31 and a weft head unit 32 are provided between the two weft curing sections 42 in the carriage 60. The configuration of the warp head unit 31 of this modification is the same as the configuration of the weft head unit 32, but the ink ejected is different.
Further, the upstream warp head unit 31a and the downstream warp head unit 31b are not provided, and the warp temporary hardening section 41 is also omitted. In this modification, the lower thread-like member t1a and the upper thread-like member t1b (therefore, the first thread-like member t1) are formed by the warp head unit 31 mounted on the carriage 60.

Hereinafter, a method for manufacturing cloth 90 according to Modification Example 2 will be described with reference to FIGS. 12 to 16. 12 to 16, a part of the warp head unit 31 and the weft head unit 32, and a part of the fabric 90 formed by the part are illustrated. In addition, the portions of the warp head unit 31 and the weft head unit 32 shown in FIGS. 12 to 16 are divided into three equal parts in the Y direction, and are designated as nozzle ranges r1 to r3 in order from the -Y direction. write down In addition, in FIGS. 12 to 16, for convenience of explanation, a part of the warp head unit 31 and the weft head unit 32 (in the enlarged view) is divided into three nozzle ranges r1 to r3, but in reality, The whole of the warp head unit 31 and the weft head unit 32 is equally divided into three nozzle ranges r1 to r3, and each nozzle range is controlled.

First, as shown in FIG. 12, the control unit 10 moves the carriage 60 (that is, the warp head unit 31 and the weft head unit 32) in the −X direction while stopping the movement of the discharge target surface 21a. Meanwhile, the nozzle N1 within the nozzle range r1 of the warp head unit 31 discharges the warp ink to form the lower thread member t1a. Here, since the conveyor belt 21 is heated by the conveyor belt heating section 71, the discharged warp ink is heated and somewhat thickened when it lands, and does not wet and spread along the discharge target surface 21a, so that the ink for the warp is heated and slightly thickened when it lands, and does not wet and spread along the discharge target surface 21a. A thread-like member t1a is formed.
Thereafter, the control unit 10 moves the ejection target surface 21a by the length of the nozzle range r1, as shown in FIG.

Next, as shown in FIG. 14, the control unit 10 moves the carriage 60 in the +X direction while stopping the movement of the discharge target surface 21a, and controls the nozzles within the nozzle range r1 of the warp head unit 31. N1 causes the warp ink to be ejected to form the lower thread-like member t1a, and the weft ink is ejected from the nozzle N2 within the nozzle range r2 of the weft head unit 32 to form the second thread-like member t2. In addition, in the nozzle range r2, the weft ink is cured by ultraviolet irradiation from the weft curing section 42 in parallel with the discharge of the weft ink, so the second thread-like member t2 is already hardened before the entire second thread-like member t2 is formed. The formed portion is hardened and becomes the weft T2.
Thereafter, the control unit 10 moves the ejection target surface 21a by the length of the nozzle range r1, as shown in FIG.

Next, as shown in FIG. 16, the control unit 10 moves the carriage 60 in the −X direction while stopping the movement of the discharge target surface 21a, and controls the warp yarn head unit 31 within the nozzle range r1. The nozzle N1 discharges the warp ink to form the lower thread-like member t1a, the nozzle N2 within the nozzle range r2 of the weft head unit 32 discharges the weft ink to form the second thread-like member t2, The nozzle N1 within the nozzle range r3 of the warp head unit 31 discharges the warp ink to form the upper thread member t1b.

Thereafter, the control unit 10 controls the movement of the discharge target surface 21a and the control of moving the carriage 60 as shown in FIG. Control for performing a discharge operation is repeatedly performed. As a result, a structure in which the first thread-like member t1 and the weft thread T2 are interwoven is formed on the discharge target surface 21a, and the structure is conveyed in the +Y direction. When the structure passes through the heating range by the warp curing section 43 shown in FIG. 11, the first thread-like member t1 is cured to form the warp T1, and a fabric 90 in which the warp T1 and the weft T2 are woven is formed. .

(Modification 3)
Next, a third modification of the above embodiment will be described. This modification differs from the above embodiment in that the warp ink and the weft ink are cured by a common curing method. This modified example may be combined with the above-described modified example 1 and/or modified example 2. Below, differences between the above embodiments will be explained, and explanations of common points with the above embodiments will be omitted.

In the above embodiment, a thermosetting ink was used as the warp ink, and an ultraviolet curable ink was used as the weft ink, but in this modification, an ultraviolet curable ink is used as both the warp ink and the weft ink. It will be done. Further, the warp temporary curing section 41 irradiates the lower thread member t1a with ultraviolet rays to temporarily harden the lower thread member t1a. Further, the warp curing section 43 irradiates the first thread-like member t1 with ultraviolet rays to harden the first thread-like member t1, thereby forming the warp thread T1.

Further, the warp ink and the weft ink have different curing speeds when cured under the same conditions. Specifically, the weft ink used is one that cures faster than the warp ink when irradiated with ultraviolet rays of the same intensity for the same period of time. As a result, when the second thread-like member t2 (weft ink) is cured by ultraviolet irradiation from the weft curing section 42 while moving the carriage 60, the lower thread-like member t1a is not completely cured, and the second thread-like member t1a is not completely cured. The weft thread T2 can be formed by selectively hardening only the thread-like member t2. Therefore, when forming the upper thread-like member t1b later, the upper thread-like member t1b and the lower thread-like member t1a can be combined, while the upper thread-like member t1b and the weft thread T2 can not be combined.

(Modification 4)
Next, a fourth modification of the above embodiment will be described. This modification differs from the above embodiment in that a release film 25 is formed on the outer peripheral surface of the conveyor belt 21. This modification may be combined with any or all of Modifications 1 to 3 above. Below, differences between the above embodiments will be explained, and explanations of common points with the above embodiments will be omitted.

FIG. 17 is a sectional view of the conveyor belt 21 according to Modification Example 4.
In this modification, a release film 25 is provided on the outer circumferential surface of the conveyor belt 21 (therefore, on the discharge target surface 21a). The release film 25 has a smaller adhesion force with the warp T1 (cured warp ink) and weft T2 (cured weft ink) than the adhesion force between the discharge target surface 21a and the warp T1 and weft T2. material is used. By providing such a peeling film 25, the fabric 90 can be easily peeled off from the discharge target surface 21a. The release film 25 may be attached to the outer circumferential surface of the conveyor belt 21 after being formed, or the material of the release film 25 may be applied to the outer circumferential surface of the conveyor belt 21 (for example, by the pretreatment unit 50) and the material is cured. It may be formed by a method.

As described above, the inkjet recording apparatus 1 according to the present embodiment includes the warp head unit group 31 that performs the first ejection operation to eject warp ink that is thermoset, and the first warp head unit group 31 that ejects the weft ink that is cured by ultraviolet rays. 2, a conveyor belt 21 having a discharge surface 21a on which the discharged warp ink and weft ink land, and a predetermined position where the warp ink and weft ink partially overlap. A control unit 10 performs ejection control to control the first ejection operation and the second ejection operation so that the ink drops land on the ejection target surface 21a in a pattern, and the warp ink and the weft ink that have landed on the ejection target surface 21a are and a curing section 40 that is cured at a predetermined timing, respectively, and the above-mentioned predetermined pattern is such that the warp ink after curing by the curing section 40 becomes the warp T1 that constitutes the fabric 90 and extends in a predetermined direction, and This is a pattern in which the weft ink after curing by step 40 becomes the weft thread T2 that constitutes the fabric 90 and extends in a direction intersecting a predetermined direction.
According to this, it is possible to form the fabric 90 in which the warp threads T1 and the weft threads T2 are woven in an independent state, that is, in a state where they are not united but separated. Therefore, a fabric 90 having stretchability, flexibility, and texture similar to ordinary fabrics woven from plant fibers or the like can be obtained.
In addition, conventional fabric manufacturing methods, such as forming threads from plant fibers and weaving the threads, require multiple complicated steps to complete the fabric, and it takes a long time to manufacture the fabric. There's a problem. In addition, the contents and equipment of each process are usually fixed depending on the type of fabric, and manufacturing a different fabric requires significant changes to the process, which is costly. There is a problem that manufacturing is difficult.
On the other hand, according to the inkjet recording apparatus 1 of the present embodiment, the fabric 90 can be formed by a simple method of discharging the warp ink and the weft ink and curing them at predetermined timings. Not only can the fabric manufacturing process be significantly shortened, but also a wide variety of fabrics can be manufactured in any quantity at low cost using common production equipment. In addition, it is possible to keep fabric inventory to the minimum necessary and reduce the amount of fabric waste.

Furthermore, by using different materials as the warp ink and the weft ink, it is possible to form the fabric 90 in which the warp T1 and the weft T2 are independent.

In addition, by using a material that does not coalesce with the warp ink when it lands at a position overlapping with the warp ink on the ejection target surface 21a as the weft ink, the warp T1 and the weft T2 can be kept independent. A dough 90 can be formed.

Moreover, one of the warp ink and the weft ink contains a hydrophilic resin, and the other contains a hydrophobic resin. According to this, it is possible to make it more difficult for the warp ink and the weft ink to coalesce when they land in an overlapping manner.

The warp ink is cured by heat curing as a first curing method, the weft ink is cured by ultraviolet curing as a second curing method different from the first curing method, and the curing section 40 It has a warp curing section 43 that cures the weft ink by thermosetting, and a weft curing section 42 that cures the weft ink by ultraviolet curing. According to this, it is possible to selectively harden any one of the warp ink and the weft ink in a situation where the warp ink and the weft ink land on the ejection target surface 21a. Therefore, for example, of the lower thread-like member t1a made of warp ink and the second thread-like member t2 made of weft ink, the second thread-like member t2 can be selectively hardened to form the weft thread T2. Furthermore, by not completely curing the lower thread-like member t1a at this stage, when the upper thread-like member t1b made of warp ink is formed later, the upper thread-like member t1b and the lower thread-like member t1a can be united. .

Further, by using heat curing as the first curing method and ultraviolet curing as the second curing method, it is possible to selectively cure any one of the warp ink and the weft ink in a simple manner.

Further, the warp ink and the weft ink according to Modification Example 3 are cured by a common curing method and have different curing speeds when cured under the same conditions.Inks having different curing speeds may be used. Even if the curing method is common, one of the warp ink and the weft ink can be selectively cured.

In addition, in the discharge control, the control unit 10 causes the warp ink to land at a position that will become a part of the warp threads T1 after curing to form a lower thread-like member t1a on the discharge target surface 21a, and forms the lower thread-like member t1a. Later, a weft ink is landed at a position where it overlaps a part of the lower thread-like member t1a and becomes the weft T2 after hardening, to form a second thread-like member t2 on the ejection surface 21a, and the second thread-like member t2 is After forming the upper layer thread member t1b, the warp ink is landed at a position that connects the adjacent lower thread members t1a and overlaps a part of the second thread member t2 to form the upper thread member t1b, and the lower thread member t1a and the upper thread member t1b are formed. A first thread-like member t1, which becomes the warp thread T1 after hardening, is formed on the discharge target surface 21a. According to this, a fabric structure in which the vertical positional relationship of the warp threads T1 and the weft threads T2 alternates can be formed using ink in a simple process.

Further, the hardening section 40 includes a warp temporary hardening section 41 that temporarily hardens the lower thread member t1a after forming the lower thread member t1a and before forming the second thread member t2. Thereby, even if the weft ink lands on the lower thread-like member t1a during formation of the second thread-like member t2, it is possible to prevent the shape of the lower thread-like member t1a from collapsing.

Further, the hardening section 40 hardens the second thread-like member t2 to form the weft T2 before forming the upper thread-like member t1b, and hardens the first thread-like member t1 after forming the first thread-like member t1. A warp thread T1 is formed. By curing the second thread-like member t2 and forming the weft T2 before forming the upper-layer thread-like member t1b in this way, the upper-layer thread-like member t1b and the second thread-like member t2 (weft T2) to be formed later can be bonded together. Coalescence can be suppressed. Moreover, since the weft thread T2 and the warp thread T1 can be hardened at different timings, it is possible to suppress the occurrence of a problem in which the weft thread T2 and the warp thread T1 coalesce.

The inkjet recording apparatus 1 also performs a first movement operation in which the ejection target surface 21a and the warp head unit group 31 are relatively moved, and a second movement in which the ejection target surface 21a and the weft head unit 32 are relatively moved. The control unit 10 further controls a first movement operation and a second movement operation in ejection control. According to this, by ejecting ink from the warp head unit group 31 at an appropriate timing in parallel with the first moving operation, the warp ink can be easily landed in an arbitrary two-dimensional pattern. Moreover, by discharging ink from the weft head unit 32 at appropriate timing in parallel with the second moving operation, it is possible to easily make the weft ink land in an arbitrary two-dimensional pattern.

The moving unit 20 also includes a discharge target surface moving unit 24 that moves the discharge target surface 21a of the conveyor belt 21, and a carriage moving unit 202 that moves the weft head unit 32 in a direction intersecting the moving direction of the discharge target surface 21a. The warp head unit group 31 is provided to be able to eject the warp ink over the fabric forming range R1 in a direction perpendicular to the moving direction of the ejected surface 21a, and the control unit 10 includes: In the discharge control, the warp head unit group 31 performs the first discharge operation while the discharge target surface 21a is moved by the discharge target surface moving section 24, and the movement of the discharge target surface 21a by the discharge target surface moving section 24 is stopped. In this state, the weft head unit 32 is caused to perform a second discharge operation while being moved by the carriage moving section 202. According to this, the warp threads T1 can be formed by simple control in which the warp ink is ejected from the same nozzle N1 of the warp head unit group 31 while moving the ejection target surface 21a. Moreover, the weft yarn T2 can be formed by simple control in which the weft ink is ejected from the same nozzle N2 of the weft head unit 32 while the carriage 60 is moved.

In addition, the warp head unit group 31 includes an upstream warp head unit 31a provided on the upstream side of a weft discharge range R2 of weft ink by the weft head unit 32, and a weft A downstream warp head unit 31b provided on the downstream side of the discharge range R2, and the upstream warp head unit 31a and the downstream warp head unit 31b are arranged in a direction perpendicular to the moving direction of the discharged surface 21a. The controller 10 is configured to be able to eject the warp ink over the fabric forming range R1, and in the ejection control, the controller 10 moves the ejection surface 21a by the ejection surface moving section 24 while moving the ejection surface 21a from the upstream warp head unit. 31a performs the first discharge operation to form the lower thread-like member t1a, and while the movement of the discharge target surface 21a by the discharge target surface moving unit 24 is stopped, the weft head unit 32 is moved by the carriage moving unit 202. The second thread-like member t2 is formed by causing the weft head unit 32 to perform a second discharge operation while moving the weft head unit 32, and while moving the discharge target surface 21a by the discharge target surface moving section 24, the downstream warp head The upper layer filament member t1b is formed by performing the first discharge operation by the unit 31b. According to this, the lower thread-like member t1a can be formed by simple control of ejecting the warp ink from the same nozzle N1 of the upstream warp head unit 31a while moving the ejection target surface 21a. Moreover, the second thread-like member t2 (weft T2) can be formed by simple control in which the weft ink is ejected from the same nozzle N2 of the weft head unit 32 while moving the carriage 60. Moreover, the upper layer thread-like member t1b can be formed by simple control in which warp ink is ejected from the same nozzle N1 of the downstream warp head unit 31b while moving the ejection target surface 21a. As a result, a fabric structure in which the vertical positional relationship of the warp threads T1 and the weft threads T2 alternate can be formed using ink in a simple process.

The curing unit 40 also forms a lower thread-like member t1a between the upstream warp head unit 31a and the weft discharge range R2 of the weft ink by the weft head unit 32 in the moving direction of the discharge target surface 21a. At the rear, a warp temporary curing section 41 is provided for temporarily curing the lower layer filament member t1a before forming the second filament member t2. According to this, even if the weft ink lands on the lower layer thread-like member t1a during formation of the second thread-like member t2, it is possible to suppress the shape of the lower layer thread-like member t1a from collapsing.

Further, the carriage moving section 202 moves the weft curing section 42 together with the weft head unit 32 in a direction intersecting the moving direction of the discharge target surface 21a. While moving with the weft head unit 32, the weft ink is cured in parallel with the second ejection operation by the weft head unit 32. According to this, while the carriage 60 is moved, it is possible to discharge the warp ink (forming the second thread-like member t2) and to form the weft thread T2 by hardening the second thread-like member t2. can. Therefore, the dough 90 can be formed in a shorter time.

Furthermore, the moving unit 20 according to the second modification includes a carriage moving unit 202 that moves the warp head unit 31 and the weft head unit 32 in a direction intersecting the moving direction of the discharge target surface 21a, and the control unit 10 In the discharge control, the warp head unit 31 and the weft head unit 32 are moved by the carriage moving unit 202 while the movement of the discharge target surface 21a by the discharge target surface moving unit 24 is stopped. Control to perform at least one of the first discharge operation by the weft head unit 31 and the second discharge operation by the weft head unit 32, and control to move the discharge target surface 21a by the discharge target surface moving section 24 are repeatedly performed. According to this, the fabric 90 can be formed using only the scanning type head unit. Therefore, since there is no need to provide a line head that covers the fabric forming range R1, the inkjet recording apparatus 1 can be simplified and the manufacturing cost of the apparatus can be reduced.

Further, the warp head unit group 31 has a plurality of nozzles N1 each discharging warp ink, the weft head unit 32 has a plurality of nozzles N2 each discharging weft ink, and the control unit 10 In the discharge control, the number of nozzles N1 used for forming the warp thread T1 among the plurality of nozzles N1 is set according to the thickness of the warp thread T1 to be formed, and the number of nozzles N1 used for forming the warp thread T1 is set according to the thickness of the weft thread T2 to be formed. The number of nozzles N2 used for forming the weft thread T2 among the nozzles N2 is set. According to this, the thread width (thread thickness) and weaving density can be easily adjusted by simple control of changing the number of nozzles that eject ink.

Further, the conveyor belt 21 is an annular belt whose outer peripheral surface forms a discharge target surface 21a, and the discharge target surface moving unit 24 moves the discharge target surface 21a by rotating the conveyor belt 21 in a predetermined circumferential path. . According to this, the discharge target surface 21a can be continuously moved in the same direction in the same section with a simple configuration. Therefore, by sequentially collecting the dough 90 formed on the ejection target surface 21a, it is possible to form the dough 90 of an arbitrary length.

The warp head unit group 31 according to Modification 1 is provided to be able to eject warp inks of a plurality of different colors, and the weft head unit 32 is provided to be able to eject weft inks of a plurality of different colors. It is being According to this, it is possible to manufacture the fabric 90 on which a pattern or image of a desired color has been formed in advance. Therefore, the step of printing a pattern or image after forming the fabric 90 can be omitted. In addition, since the threads that make up the fabric can be colored themselves, problems such as ink bleed through, insufficient ink ejection, and moire with the fabric structure are avoided when printing images on fabric using an inkjet method. There are benefits that do not arise.

The inkjet recording apparatus 1 also includes a pre-processing section 50 that performs predetermined pre-processing on the ejection target surface 21a before the warp ink and the weft ink are ejected onto the ejection target surface 21a. According to this, the warp ink and the weft ink can be in a more appropriate state after landing, and the fabric 90 can be more easily peeled off after being formed.

Further, the pretreatment unit 50 applies a liquid repellent agent that increases the liquid repellency to at least one of the warp ink and the weft ink to the ejection target surface 21a. According to this, it is possible to suppress the occurrence of a problem in which the warp ink and/or the weft ink after landing wets and spreads on the ejection target surface 21a.

Furthermore, in the inkjet recording apparatus 1 according to the fourth modification, the adhesion force between the warp T1 and the weft T2 after being cured by the curing unit 40 on the ejection target surface 21a is the same as the adhesion force between the ejection target surface 21a and the warp thread T1 and the weft thread T2. A release film 25 is provided which is smaller than the force. According to this, the fabric 90 after formation can be more easily peeled off.

Further, in the method for manufacturing the fabric 90 according to the present embodiment, the first ejection operation and the second ejection operation are performed so that the warp ink and the weft ink land on the ejection target surface 21a in a predetermined pattern that partially overlaps. and a step of curing the warp ink and the weft ink that have landed on the ejection target surface 21a by the curing section 40 at predetermined timings, and the above predetermined pattern is formed after curing by the curing section 40. A pattern in which the warp ink becomes the warp T1 that constitutes the fabric 90 and extends in a predetermined direction, and the weft ink after curing by the curing section 40 becomes the weft T2 that constitutes the fabric 90 and extends in a direction intersecting the predetermined direction. It is. According to such a method, it is possible to easily produce the fabric 90 that has the same elasticity, flexibility, and texture as ordinary fabrics woven from plant fibers or the like.

Note that the present invention is not limited to the above embodiments, and various changes are possible.
For example, in the above embodiment, a thermosetting ink is used for the warp ink, and an ultraviolet curable ink is used for the weft ink, but the present invention is not limited to this. Thermosetting ink may also be used.

Alternatively, a hydrophilic resin may be dispersed in the warp ink, and a hydrophobic resin may be dispersed in the weft ink.
Furthermore, the compositions of the warp ink and the weft ink are not limited to those exemplified in the above embodiments, and may be any material that does not coalesce with each other when they land in overlapping positions.

Furthermore, the ejection mechanisms of the warp ejection head 312 and the weft ejection head 322 are not limited to the shear mode. For example, a vent that discharges ink from nozzle N1 by installing a piezoelectric element such as a piezo element on the wall of a pressure chamber that communicates with the nozzle, and causing pressure fluctuations in the ink within the pressure chamber by deforming the piezoelectric element (therefore, the pressure chamber). A mode discharge mechanism may also be used. Furthermore, the present invention is not limited to the method of deforming the pressure chamber, and for example, a thermal type ejection mechanism that ejects the ink by generating bubbles in the ink by heating may be used. Further, different types of discharge mechanisms may be used for the warp discharge head 312 and the weft discharge head 322.

Moreover, the upstream warp head unit 31a and the downstream warp head unit 31b may have a single warp discharge head 312.
Moreover, the weft head unit 32 may have a single weft discharge head 322.

Further, the downstream warp head unit 31b may be omitted. That is, after the formation of the lower thread-like member t1a by the upstream warp head unit 31a and the formation of the weft thread T2 by the weft head unit 32, the forming portion of the lower thread-like member t1a and the weft thread T2 is transferred to the upstream warp head unit. The discharge target surface 21a may be moved back in the -Y direction so as to return to the upstream side of 31a, and then the upper layer thread member t1b may be formed by the upstream warp head unit 31a.

Further, in the above embodiment, the weft curing section 42 is mounted on the carriage 60, and the weft ink (second thread-like member t2) immediately after landing is cured while the carriage 60 is moving. Not limited to. For example, in a case where the weft ink becomes gel-like immediately after landing and can maintain its shape, the weft curing section 42 is not mounted on the carriage 60, and the weft ink is not mounted on the carriage 60, but downstream of the movement range of the carriage 60 in the movement direction of the discharge target surface 21a. It may be placed on the side. In this case, the weft curing section 42 is configured to be able to irradiate ultraviolet rays onto the ejection target surface 21a within a width range including the fabric forming range R1 in the X direction. Then, after forming the second thread-like member t2, the discharge surface 21a is moved in the Y direction, and the second thread-like member t2 is cured when passing through the ultraviolet ray irradiation range by the weft curing section 42. .

Furthermore, in the embodiment described above, the weft head unit 32 is mounted on the carriage 60, but the present invention is not limited thereto. For example, a weft head unit 32 having a line head similar to the upstream warp head unit 31a and the downstream warp head unit 31b is installed between the upstream warp head unit 31a and the downstream warp head unit 31b. The lower thread member t1a, the second thread member t2, and the upper thread member t1b may all be formed by a single pass method. In this case, the carriage 60 and carriage moving section 202 can be omitted.

Furthermore, the pretreatment section 50 is not limited to one that applies a liquid repellent. For example, a curing agent that causes particles in the ink to aggregate and harden upon contact with the warp ink and/or the weft ink may be applied to the ejection target surface 21a.

Furthermore, the weaving method of the fabric 90 to be formed is not limited to the plain weave, but by replacing the warp pattern data 141 and the weft pattern data 142, various weaves such as a twill weave as shown in FIG. 18 and a satin weave as shown in FIG. The dough 90 can be formed by the method.

Further, although the explanation has been given using an example in which the warp threads T1 and the weft threads T2 of the fabric 90 are orthogonal to each other, the present invention is not limited to this, and the warp threads T1 and weft threads T2 may intersect at an angle other than 90 degrees. For example, by shifting the nozzle N1 that discharges the warp ink in the X direction in accordance with the movement of the discharge target surface 21a, the first thread member t1 (therefore, the warp T1) is tilted with respect to the Y direction.
