Description

  TECHNICAL FIELD The present invention relates to a crease processing apparatus and a crease processing method for garments, and in particular, slacks for men and pleats for women that can manufacture a large number of products in which a center line is formed with a simple configuration in a short time. The present invention relates to a crease processing apparatus for clothes such as a skirt and a crease processing method for clothes.

  Folded garments such as men's slacks center pleats and women's pleated skirts are functional to express a three-dimensional design as well as the appearance. Such slacks and skirt pleats are usually creased by pressing with an iron after applying a chemical solvent by post-processing after the fabric is woven.

  However, even when the crease is firmly in place at the time of purchase, the crease may disappear if worn repeatedly or wet with rain. The following three methods are known as methods for making a crease in such clothing.

<Hot press processing>
Hot press processing is a crease processing method using a so-called iron press, which releases hydrogen bonds inside the fiber by giving sufficient moisture to the fabric before pressing, and regenerates hydrogen while skipping moisture by the heat of the iron. The folds are fixed by using the coupling.

<White set processing>
Siroset processing is a processing method that creases wool products in particular, and uses L-cysteine, a natural amino acid, to release the cystine bond of the wool molecule and then rebond it in the creased state. The folds are fixed by storing the shape in the wool molecule.

<Lintrak processing>
The Lintrac process is to apply a crease processing resin developed by The Woolmark Company on the lining of the press-finished fabric and let it dry naturally to fix the crease.

  The three methods described above are processing methods mainly performed on a finished product, and are processing methods for a state in which a crease has already been formed.

  Patent Document 1 discloses a crease processing method for clothing. The crease processing method includes a first step in which a seam is formed using an upper thread and a lower thread along a crease line of clothing, and heating and heating are performed in a state in which the seam is folded along the seam line. And a second step of pressing, using a synthetic resin yarn for fiber bonding as the lower yarn, and having a third step of removing the upper yarn after heating and pressurizing in the second step.

  However, in the case of the crease processing method shown in Patent Document 1, the upper thread remains in the fold (mountain fold portion) on the front side of the fabric unless it passes through the third step of removing the upper thread. There is a problem that it takes a lot of time and labor to remove it manually.

  In addition, if the upper thread is pulled to remove the upper thread in the third step after being heated and pressurized in the second process and fused to the fold (valley fold) on the back side of the fabric, the upper thread becomes the lower thread (for fiber bonding) When the upper thread is pulled out, the lower thread creates a slight whisker-like shape in both the mountain folds and the valley folds. There was a problem that it was tingling or when it was touched from the front side, the feeling of roughness remained.

  For this reason, the present applicant has proposed a crease processing method for clothing as shown in Patent Document 2. According to this method, a water-soluble upper thread and a lower thread made of a thermosetting adhesive resin are sewn along a line where a crease is desired on the fiber fabric, and the lower thread is sandwiched along the crease line. Since the steam pressing is performed in such a bent state, it is possible to form folds (pleats) that are resistant to moisture and that are durable in a simple process.

  In addition, by using a water-soluble thread for the upper thread, the lower thread is fused to fix the crease when steam pressed, but the upper thread is melted away by steam (water vapor), so the upper thread is removed. Such an operation is not necessary, and not only can the fold be more beautiful, but also the effect that an extra work process can be omitted can be expected.

JP2013-245412A Japanese Patent Application No. 2017-050534

  However, according to Patent Document 2, although it is possible to form a durable crease resistant to moisture in a simple process, after sewing the upper thread and lower thread with a sewing machine or the like, the center line is bent, There is a problem in that there is a limit to the number of products that can be manufactured within a predetermined time, in other words, there is a limit to mass production of products because it involves a process of performing steam pressing.

  Hereinafter, a crease processing apparatus and a crease processing method for clothing according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a crease processing apparatus for clothing according to an embodiment of the present invention.
As shown in the figure, a crease processing apparatus 100 for clothing according to an embodiment of the present invention includes a fiber fabric 1, a first roller 2, a conveyor belt 3, a crease groove forming tool 4, and a heating apparatus 5. The adhesive thread placement tool 6, the negative pressure suction device 7, the adhesive thread welding tool 8, the heating device 9, and the second roller 10.

  In the above configuration, the first roller 2 sends the fiber dough 1 wound around the roll to the transport belt 3. The conveyance belt 3 is a conductive belt, and conveys the fiber fabric 1 fed from the first roller 2 in the direction of the arrow in the drawing for crease processing. FIG. 3A is a perspective view of the conveyor belt 3. As shown in the figure, the belt portion has a slit 30 formed at the center in the length direction. FIG. 3B shows the positional relationship among the heating device 5, the negative pressure suction device 7, and the heating device 9 provided below the conveyor belt 3.

  The crease groove forming tool 4 is made of metal and has a convex cross section. The tip of the convex portion 41 is formed with a curvature. The convex part 41 of the crease groove forming tool 4 is formed to a length corresponding to the length of the crease groove to be formed, as shown in FIG. The crease groove 40 is formed by pushing down the crease groove forming tool 4.

  A heating device 5 is disposed on the lower surface side of the conveyor belt 3 facing the crease groove forming tool 4. The heating device 5 is made of, for example, IH or the like, and heats the fiber fabric 1 from below using induction heating generated between the crease groove forming tool 4 as shown in FIG.

  The adhesive thread placement tool 6 is for hanging and placing an adhesive thread 60 made of a thermosetting adhesive resin in a crease groove 40 formed in the fiber fabric 1. The adhesive yarn 60 is wound around the adhesive yarn supply roll 50, and the adhesive yarn 60 having a required length depending on the length of the crease groove 40 formed in the fiber fabric 1 is suspended and supplied.

  As shown in FIG. 2B, a negative pressure suction that sucks the adhesive yarn 60 arranged in the fold groove 40 with a negative pressure at a position on the lower surface side of the conveying belt 3 and facing the adhesive yarn arranging tool 6. A device 7 is provided.

  The negative pressure suction device 7 is provided because the negative pressure suction device 7 may cause the adhesive yarn 60 to be placed in the crease groove 40 without being tightly spaced by simply dropping the adhesive yarn 60 into the crease groove 40. The suction is arranged in the crease groove 40 without any gap.

  The adhesive yarn welding tool 8 is made of metal and welds the adhesive yarn 60 sucked by the negative pressure of the negative pressure suction device 7 to the crease groove 40 and hardens it. Similar to the crease groove forming tool 4, the adhesive yarn welding tool 8 is formed with a convex cross section. The tip of the convex portion 81 is also formed with a curvature, similar to the crease groove forming tool 4. As shown in FIG. 2D, the convex portion 81 of the adhesive yarn welding tool 8 is formed to have a length corresponding to the length of the crease groove.

  In the case of the convex portion 81 of the adhesive yarn welding tool 8, the protruding portion is formed longer than the convex portion 41 of the crease groove forming tool 4. This is because the adhesive yarn 60 needs to be welded while being pushed into the crease groove 40, and the length is required accordingly. A heating device 9 is disposed on the lower surface side of the conveyor belt 3 facing the adhesive yarn welding tool 8. This heating device 9 is made of, for example, IH or the like, similar to the heating device 5, and as shown in FIG. 2 (c), the fiber fabric 1 using induction heating generated between the bonding yarn welding tool 8. Is heated from below.

  By pressing down the adhesive yarn welding tool 8, the adhesive yarn 60 is welded and cured in the crease groove 40 of the fiber fabric 1 by the pressing and the heat of the heating device 9.

  The second roller 10 winds the fiber fabric 1 in which the adhesive yarn 60 is welded and cured to the fiber fabric 1 and the crease processing is completed.

Hereinafter, the operation of the crease processing by the crease processing apparatus for clothing according to the embodiment of the present invention will be described.
First, the fiber fabric 1 wound around a roll is sent from the first roller 2 to the transport belt 3. The fiber fabric 1 delivered from the first roller 2 is conveyed by the conveying belt 3 in the direction of the arrow in the figure.

  When the fiber fabric 1 is conveyed, the crease groove forming tool 4 is pushed down to a predetermined position of the fiber fabric 1 to press the fiber fabric 1 (FIG. 2 (a)).

  Since the heating device 5 made of IH or the like is disposed on the lower surface side of the conveyor belt 3 facing the crease groove forming tool 4, when the crease groove forming tool 4 is pushed down, the pressing and the heating device 5 Due to the heat, the U-shaped crease groove 40 corresponding to the convex shape of the crease groove forming tool 4 is neatly formed on the fiber fabric 1 as if it was pressed with an iron.

  Then, the crease groove forming tool 4 is returned to the original position, and the fiber fabric 1 in which the U-shaped crease groove 40 is formed is moved to the position of the next adhesive thread arranging tool 6 by the transport belt 3.

  When the fiber fabric 1 in which the crease groove 40 is formed moves to the position of the adhesive thread placement tool 6, the adhesive thread 60 wound around the adhesive thread supply roll 50 is suspended in the crease groove 40 and cut at a required length. (FIG. 2B).

  At this time, there is a possibility that the adhesive yarn 60 may not be disposed in the crease groove 40 without a gap just by placing the adhesive yarn 60 in the crease groove 40. Therefore, the negative pressure suction device 7 disposed on the lower side of the conveying belt causes the adhesive yarn to be disposed under negative pressure. 60 is sucked and arranged in the crease groove 40 without a gap.

  When the bonding yarn 60 is disposed in the crease groove 40 without a gap, the negative pressure suction is stopped, and the fiber fabric 1 is moved to the position of the next bonding yarn welding tool 8 by the transport belt 3.

  When the fiber fabric 1 in which the adhesive yarn 60 is disposed in the crease groove 40 moves to the position of the adhesive yarn welder 8, the adhesive yarn welder 8 is pushed down to the position of the crease groove 40 to press the fiber fabric 1 (FIG. 2 ( c)).

  A heating device 9 made of IH or the like is disposed on the lower surface side of the conveyor belt 3 facing the adhesive yarn welding tool 8, so that when the adhesive yarn welding tool 8 is pushed down, the tip of the heating device 9 becomes a crease groove 40. The adhesive yarn 60 is welded and cured in the crease groove 40 of the fiber fabric 1 by the contact with the arranged adhesive yarn 60 and by the press and the heat of the heating device 9. Then, the adhesive thread welding tool 8 is returned to the original position.

  Thereby, the crease process with respect to the fiber fabric 1 is completed. The fiber fabric 1 that has been subjected to the crease processing is moved by the transport belt 3 and wound around the second roller 10.

  After the fiber fabric 1 having been creased is wound on the second roller 10, processing into various kinds of clothes as other processes, such as center pleats for men's slacks and pleat skirts for women, etc. Processing into creased garments is performed.

  The crease processed through the above steps is maintained in a state where the valley fold portion on the back side of the crease groove of the fiber fabric is slightly adhered by the thermosetting resin, so it is resistant to moisture and firmly on the front side of the fabric The folds (pleats) made can be sustained.

  As described above, a U-shaped fold groove is formed by pushing the fiber fabric with a fold groove forming tool and a heating device while being conveyed by the conveyance belt, and bonded to the fold groove from the adhesive yarn supply roll. The yarn is suspended and sucked with a negative pressure suction device, and the adhesive yarn is placed in the crease groove without any gaps. The adhesive yarn is pressed and heated by the adhesive yarn welding tool and the heating device, and the adhesive yarn is welded and cured in the crease groove. As a result, it is possible to manufacture a large number of products in which a center line is formed with a simple configuration in a short time.

  In addition, in conventional crease processing, for example, siroset processing, a method of releasing the cystine bond of the wool molecule with a chemical solution and making a crease and rebonding is used, but if such a solvent is used, the fiber fabric may be damaged. There was a problem that the crease could be removed after washing several times. However, in the present invention, the fiber fabric is not damaged because the fabric is welded to the fiber fabric using an adhesive thread. Since the dough and the adhesive yarn are firmly welded, there is an effect that it is difficult to remove the crease even if washed many times.

  In the above-described embodiment, the convex portion 41 of the crease groove forming tool 4 is formed to be long so as to correspond to the length of the crease groove to be formed. For example, FIG. ), A protrusion 42 having a short length and a curvature at the tip may be formed.

  In this case, when the crease groove forming tool 4 is pushed down, the protrusion 42 pushes down one point of the fiber fabric 1, but the fiber fabric 1 on the transport belt 3 moves toward the second roller 10 at a constant speed. Therefore, the crease groove 40 is automatically formed at the one point where the protrusion 42 is pushed down. The crease groove forming tool 4 is returned to the original position, and the same operation is repeated at a predetermined time interval.

  Similarly, as shown in FIG. 4B, the bonding thread welding tool 8 may also be formed in a short length and a protrusion 43 having a curvature at the tip. Even in this case, since the fiber fabric 1 on the conveyor belt 3 is moving in the direction of the second roller 10 at a constant speed, the adhesive yarn 60 in the crease groove 40 is in contact with the protrusion 43 in a single turn and continuously. It is welded and cured. The adhesive yarn welding tool 8 is returned to the original position, and the same operation is repeated at a predetermined time interval.

  With such a configuration, it is not necessary to make the length of the conveyor belt 3 long, so that the manufacturing cost of the apparatus can be kept low. Further, since the conveyor belt 3 can be operated continuously without intermittent operation, the control is not complicated and the power consumption can be reduced.

  Further, in the above example, the fiber fabric 1 wound around the first roller 2 is transported by the transport belt 3, and the fiber fabric 1 subjected to the crease processing is wound from the two rollers that are wound up by the second roller 10. However, the present invention is not limited to this, and the first roller 2 and the first roller 2 can be used as long as the fiber fabric 1 is supplied to the conveyor belt 3 and can accommodate the creased fiber fabric 1. The configuration including the second roller 10 may not be used.

  Further, in the step of welding and hardening between the adhesive yarn welding tool 8 and the heating device 9, the adhesive yarn 60 arranged in the crease groove 40 is not sucked by negative pressure, but this is not restrictive. Even at this stage, the adhesive yarn 60 may be welded and cured while applying a negative pressure by the negative pressure suction device 7.

  Furthermore, in the above example, the crease groove 40 is formed in the length direction of the fiber fabric 1, the adhesive yarn 60 is disposed in the length direction of the fiber fabric 1, and the adhesive yarn 60 is aligned along the length direction of the fiber fabric 1. However, the present invention is not limited to this. For example, the crease groove 40 is formed in the width direction, the adhesive yarn 60 is disposed in the crease groove 40 in the width direction, and the bonding is performed in the width direction. The yarn 60 may be welded and cured in the crease groove 40.

  Furthermore, in the above example, an example in which one fold groove 40 is formed is shown, but the present invention is not limited to this. For example, if a plurality of crease grooves 40 are formed in the wide fiber fabric 1 and the above-described crease processing step is executed in each row, the fiber fabric 1 subjected to the crease processing can be produced in large quantities.

  It should be noted that depending on the type of the fiber fabric 1, the thickness of the fiber fabric 1, the thickness of the bonding yarn 60, and the like, it is necessary to change the control. For example, when the fiber dough 1 is different, it is necessary to change the rotation speed control for carrying out and winding the first roller 2 and the second roller 10. Also, it is necessary to vary the control of the conveying speed of the conveying belt 3.

  In addition, it is necessary to change the temperature control of the heating device 5 and the time control of electromagnetic irradiation. Also, it is necessary to make the control of the pressing force of the convex portions 41 and 81 of the heating devices 5 and 9 different from the vertical (Z) and horizontal (X) vertical (Y) movement speed control and the push-down control.

  Also, it is necessary to vary supply speed control and heating control depending on the type (material) of the adhesive yarn 60, the welding temperature, the thickness, the elastic modulus, and the like. Further, the negative pressure control of the negative pressure suction device 7 also needs to vary the pull strength and the wind width control according to the various conditions described above.

  Such various dynamic function control is realized by a system application by IT (Information Technology) that moves all of them synchronously according to the material of the fiber fabric and the adhesive yarn.

  To do so, attach all necessary sensors to all of the above devices and equipment, and make full use of “IoT” (Internet of Things), which transmits and receives various data in real time based on information from the sensors. To synchronize the various speeds. Thereby, mass production can be realized.

  Furthermore, if the latest IT equipment and nanotech materials are introduced, the rotation speed of manufacturing can be increased with the progress of equipment and the evolution of materials. The production efficiency is greatly improved by the "manufacturing machine".

  It can be used for continuous processing of folds such as clothing. Combining this with innovative technologies, sensors, IT / applications, and a total system will enable us to realize a remarkable mass production of creased products in the textile field.
