Fabric reinforcement method using fluid reinforcement material

1 is a cross-sectional view of an apparatus for practicing the method of the present invention.

2 is a vertical sectional view taken along the line II-III of FIG.

3 is a side view showing a modification of the device.

4-8 are some plan views of fabric pieces reinforced by the present invention.

9 shows a different pattern of reinforcing materials that can be used in accordance with the present invention.

The present invention prints a pattern of reinforcing material on one side of the fabric in the form of a fluid, i.e. a solution, an emulsion, a suspension or a fluidized powder, in particular so that the reinforcing material does not penetrate the other side of the fabric and cures the reinforcing material (i.e. polymerizes). Vulcanization, crosslinking) to form a resilient or plastic material that reinforces the fabric by making it firmly attached to the fabric.

In another aspect, the present invention is a device for printing a pattern of the reinforcing material on the fabric to cure it to cure the support member for supporting the other side of the fabric and the reinforcing material printed on the fabric so as to print the pattern of the reinforcing material on one side of the fabric Reinforcing device of the fabric formed by means of a.

As an example of a known fabric reinforcement method and device disclosed in British Patent No. 1,201,941, in this case, plastic is printed on the bottom of the top cloth to obtain a substitute for inter lining. It is. In the case of this patent, an open sheet or an open roller capable of supplying a paste therein is used to make a resin to be used as a paste and to print it onto a top cloth. In this case, the sheet or roller has a precisely formed pattern having a diameter of 1.2 to 3 mm, and the reinforcing material having different densities is printed on the bottom surface of the problem surface by this pattern, thereby showing various printing characteristics.

However, the method and apparatus described in the UK patent is not suitable for mass production because different pieces of cloth of clothes and different sizes of clothes are required for different printing members, and thus a special printing pattern is required. Moreover, the British patent does not describe the properties of the reinforcing material that is printed on the fabric at all, and in practice, the reinforcing device of the fabric depends on the nature of the material being printed, as well as on factors such as the printing pressure. have.

In addition, the special printing pattern disclosed in the above-mentioned British Patent No. 1,201,941 is formed by parallel lines of two intersecting rows, and has a relatively large circular spot at the intersection of the parallel lines. The parallel lines do not have to cross at right angles, for example in this case the pattern has a slight orientation, resulting in different tensile and elastic properties in different directions, but generally the orientation of the reinforcement material It is relatively small compared with that given by.

It is an object of the present invention to provide a method and apparatus which can be used to print reinforcing materials in large quantities in fabrics and which can be used to improve the properties of the reinforcement itself.

According to the present invention, in printing the reinforcing material on the fabric, a printing member having a shape similar to the pattern printed on the fabric is used, and the printing member extends over the entire surface of the fabric but cooperates with the reinforcing material at predetermined intervals. It is capable of printing a pattern on at least some limited discontinuities of the fabric. By adopting this method, the reinforcing material can be printed on several different pieces of fabric by using the same printing member, for example, the fabric is properly placed so that the pattern is laid in the direction of the fabric's weft. Can be oriented. The printing member itself can be of any suitable form, for example a screen or a mask with a spray head, but printing cylinders are particularly preferred.

According to the invention, the device is arranged so that a wide gap can be formed between the printing member and the supporting member so that even if the fabric is drawn out through the printing member, the pattern is not printed on the continuous part of the fabric and the pattern is restricted to at least another part of the fabric. It can cause printing on discontinuities.

According to a variant of the invention, the reinforcing material can be printed onto the fabric in the form of a pattern of continuous or discontinuous parallels, in particular without a connection between the parallel lines in the transverse direction to the parallel, in which case the pattern can be printed on the fabric to which the reinforcing material is printed. Go straight across. This reinforcement gives a greater directionality to impart different properties to the fabric in different directions and give the reinforced fabric the properties of a fabric reinforced in a conventional manner as a conventional double-endothelium, known as a canvas. . "Canvas" type double inner skin refers to a fabric woven from different yarns of strings and blades with a slight elasticity in the string direction but not elasticity in the warp direction.

A conventional approach is to sew or join a "canvas" type double endothelium such that the string is laid horizontally, for example, behind the front panel (front) of the jacket. With the present invention, the continuous degree discontinuous parallel lines can be laid horizontally (parallel to the direction of the string of the fabric of the superficial fabric) and when the fabric is bent around the horizontal line, the fabric becomes flexible but is bent around the vertical line. There is very good at the elasticity of the fabric. In addition, parallel lines can be easily folded around the cuffs or bottoms in order to reduce or lengthen the sleeves or bottoms, for example, if they are printed on the jacket cuffs or bottoms of the bottoms. The fold line comes between the parallel lines of the reinforcement material.

According to another variant of the present invention, in printing the reinforcing material to the fabric, it is possible to use a member having a recess for forming a pattern as a printing member and the reinforcing material is in the range of 13,000-20,000 centipoise (cp) as described below. Has a Brookfield field viscosity of. Using the viscosity in this range, it has been found that the printing member can be used to quickly prevent printing of the reinforcing material into the fabric while printing, and the printing operation can be carried out by ordinary commercial operation.

According to another modification of the present invention, in addition to the above, it is possible to use a printing cylinder as the printing member, and if desired, the distance between the printing member and the supporting member may be different, as well as using the same reinforcing material and the printing member and the printing speed. It can print various types of fabric. The fact that the same reinforcing material can be used as long as the distance between the printing member and the supporting member can be changed depending on the fabric means that the printing process can be performed at a very simple and low cost.

Each of the above-described features of the present invention can contribute to amelioration of all the drawbacks of the prior art, and it is preferable to use all of the above-mentioned features of the present invention together, but it is not necessary to do so. For example, if a printing cylinder uses grooves extending only 2/5 of its length instead of having grooves throughout its length, the uncut fabric can print 2/5 of its width. Although difficult to do and waste of reinforcing material, the fabric can be cut after printing. In this way, even if there is some waste of the reinforcing material, the overall width and length of the uncut fabric can be printed with the reinforcing material as a more advantageous method than the prior art.

In some cases, the line of the pattern may be interconnected with each part of the pattern extending in the transverse direction of the line. Also, the printing member may be used to print a pattern matching the part or panel to be cut as long as it is appropriate, in which case the lines of the pattern to be printed on different parts or panels do not need to be parallel to each other.

As can be seen from the foregoing, the method of the present invention can be used for fabric pieces (parts or panels) which are not cut fabrics, but are cut for apparel, but are particularly preferably used for cut fabric pieces.

Examples of garments and fabric types in which the present invention can be used are, for example, men's coats, such as jackets and overcoats, but can also be used for garments such as a chassis, in which case the reinforcing material can Buttons can print on a string. The present invention can be used for fabrics with a wide range of weights, from fabrics for chassis to light overcoats to heavy overcoats. The present invention can also be used for double endothelium, such as chest felt, collar and jacket shoulder pads. In the special case of using double-endothelium, the reinforcement material is printed on the inside of the upper cover, and the upper cover is further heat-treated if the upper cover is bonded to the double-endothelium using the reinforcing material in the initial hardened skin or if the reinforcing material has some thermoplastic properties. Bound to double endothelium in stage.

The fabric may be woven by any suitable method such as, for example, weaving, knitting or felt manufacturing, and the material may be any suitable material such as wool, silk, cotton, or a mixture of natural and synthetic fibers.

Suitable as the printing pattern of the reinforcing material is a pattern consisting of continuous or discontinuous parallel lines, especially without cross interconnects in the transverse direction with respect to the parallel lines, and is most convenient when the distance of each line is the same.

In general, the shape of the printing member preferably has parallel lines having a width of about 1 mm and a distance of about 1 mm between each line. Thus, the printed pattern has a line of about 1 mm or slightly wider width depending on the dispersion of the reinforcing material and has a spacing of about 1 mm or slightly narrower in each line.

In special cases, such as in the collar of the rear panel of the jacket, each line may extend at an angle of no more than 90 ° to the direction of the fabric's blade and line. Nevertheless, it has been found that for most garments it is best to have a line extending parallel or almost parallel to the fabric's line. For this reason, it has been found that the pattern has a parallel line extending in the transverse direction with respect to the direction of movement of the fabric passing through the printing member. In forming a line in a printing cylinder, it is easy to engrave differently oriented lines, such as diagonal lines or circumferential lines, but in the case of a special printing cylinder, it is relatively easy to engrave grooves extending in parallel to the cylinder side.

The reinforcement strength or orientation can be changed by printing the pattern twice on the same or different parts of the fabric (especially in the case of double endothelium), and by rotating the fabric, the two patterns can be printed 90 ° to each other. .

In general, printing patterns at 90 ° to each other in different parts of the double endothelium yields better properties than when these patterns are printed twice in one part.

When used on a piece of cloth, such as a breast pocket attached to the jacket's front panel, or on a part such as the dart of the jacket, a mask, such as a piece of teflon-film, may be applied to the fabric. For example, temporary cutting pieces may be used for the fabric. Teflon typically does not absorb reinforcing materials and can be reused without washing. The amount of reinforcing material is generally rigid and delicate fabrics, which require less reinforcing material, that is, thinner printing layer of reinforcing material. Depend on factors such as surface tension and the pressure applied to the reinforcing material.

In general, however, the amount of material cured in the fabric, for example in textiles used in jackets or trousers, in particular woven fabrics, is suitable in the range of 15-60 g / m 2 (g / m 2 fabric), but in special cases such as double endothelial, this figure is 100 g / It becomes high about 2 m <2>. In general, the weight ratio of the cured material to the weight of the fabric (when basis weight without reinforcing material) is suitable in the range of 7.5-20% or 30%, and in the case of conventional fabrics such as woven fabrics the range of 9-16% is suitable. Do.

The amount of cured reinforcement in the fabric can be expressed as the weight of reinforcement per meter of line if the pattern includes lines, and good results are obtained when the weight per meter of line is in the range of 0.04-0.15 g and the woven top For felt, the range of 0.06-0.10 g is suitable.

When the printing member used to achieve the weight in this range is a plate or a cylinder having grooves, it is suitable that the groove length is 0.05-1 mm, more particularly in the case of 0.25-0.35 mm. However, the actual amount of reinforcing material transferred from the groove to the fabric depends on the printing pressure and the nature of the fabric itself.

For example, even if the support member is of a carbon type, in order to support the other side of the fabric, there is a predetermined gap between the printing member and the support member, and in general, the width of the gap is appropriately in the range of 0.1-0.5 mm. . Within this range the reinforcement can be printed satisfactorily with most conventional fabrics. In the smaller range, the maximum width is 0.4 mm. In general, the higher the pressure, the more penetration is required, so in the case of a very delicate fabric such as a shading fabric, there is no need to apply pressure by the printing member, and the spacing is only slightly larger than the thickness of the fabric. With a suitable choice of spacing, the same spacing can be used for relatively thick and open woven fabrics and for relatively thin and close woven fabrics. The spacing that can be used for various fabrics is about 0.15 mm. Since thick fabrics are strongly pressured, the reinforcing material penetrates well into the fabric, and thin fabrics have less penetration of the reinforcing material.

The printing speed is most convenient when the printing member is a printing cylinder of about 20m per minute, and the printing cylinder has a main speed that can be adjusted to the most convenient printing speed. In the case of the present invention, in general, the reinforcing material may be used in the form of a solution or a dispersion and a curing form of any suitable resin or elastomer, but the reinforcing material is preferably used in a dispersible form in water. It is preferable to harden | cure below. More preferably, the reinforcing material is cured within 5 minutes at 140-150 ° C. immediately after printing or printing.

Suitable as the reinforcing material are thermosetting polyacrylic resins such as those in which the monomers contain acrylic groups such as acrylic acid itself, acrylamide, acrylonitrile, or acrylates such as ethyl acrylate or butyl acrylate. Any suitable crosslinking agent may be added, and a melamine agent is suitable as a crosslinking agent when the reinforcing material is composed of a polyacrylic resin. The cured material should have a high degree of crosslinking, especially not less than 120 ° C. The curable material must also be resistant to dry cleaning fluids.

If desired, the reinforcing material may be bubbled by blowing air into the reinforcing material, for example, before supplying the reinforcing material to the printing member, but bubbles are not preferred.

The strength of the reinforcing material is obtained by the combination of the cured reinforcing material and the fabric fibers adhered thereto. In general, the more penetration, the greater the reinforcement and elasticity of the fabric. Very rigid translucent fabrics, such as a satin fabric, should be virtually devoid of penetration and the reinforcement attaches directly to the delicate fine hairs or piles of the fabric, but penetration is most appropriate at 10-33% of the fabric thickness.

As mentioned above, penetration depends on the viscosity of the reinforcing material, the shape of the fabric and the pressure of the printing member. If the reinforcing material contains a liquid, the viscosity at the time of measurement depends on the type of device used and the strain of the reinforcing material because the reinforcing material is thixotropic. However, effective viscosity measurements are A.S.T.M. It has been found that this can be achieved by D1, 824-61T. However, instead of the test conditions specified in the ASTM Standard Test Method, the Brookfield Model RVK Viscometer uses speeds of spindle no. 4 and 5 rpm and the temperature is used when printing reinforcement materials. Is the temperature.

As used herein, Schönbrunn field viscosity ＂refers to the viscosity measured by this method. It has been found that the Brewuk field viscosity should be broad in the range of 10,000-25,000 CP or narrow in the range of 13,000-20,000 CP.

Good results are obtained when operating in the range of 15,000-17,000 CP, a suitable Brookfield viscosity is about 16,000 CP, 17,000 CP can be used with slight pressure for very light fabrics, and 15,000 with strong pressure for heavy fabrics. CP may be used. If other viscometers are used, the results vary significantly.

For example, the use of rotor No. 1 and scale No. 1 in a VT-OZ type Haake viscometer is used to measure reinforcing materials having a Brookfield viscosity of 16,000 CP. Viscosity is 3,500 CP. The effective viscosity range obtained using such a Haaki viscometer is 2,900-3,700 CP. One poise is 1 cm ⁻¹ g ㎳ ⁻¹ .

The viscosity can be adjusted by adding an inert liquid such as water or by adding a weighting agent such as cured acrylic resin. There is no need for a specific viscosity to suppress undue penetration. If the reinforcement material is too viscous, too much reinforcement remains on the surface of the fabric, and the adhesion is large even when a lot of filler is added. In addition, for example, it is difficult to wipe off the unprinted portion of the printing member.

The actual adhesion of the reinforcement material can be controlled by inert fillers such as talc or inorganics such as titanium dioxide or powdered asbestos alumina, and the fillers also control the amount of dispersion of the reinforcement material when printed on the fabric. That is to say, there is a printing stability to the fabric. Particularly, the filler is suitable for having 90w / w% or more of the particles having a particle size of more than 1μ, and if 50% of the particles are extremely fine powders having a particle size of more than 5μ, the adhesion does not change and is considerably well. On the other hand, the larger the particle size, the better the elasticity but the lower the adhesiveness.

For example, it has been found that the total particles of pigment grade titanium dioxide are beneficial in the case of a mixture of fine fillers having a particle size of less than 1 μ and significantly increase the hardness of the cured reinforcing material. Suitable amounts of fine fillers are 0.5-1 w / w of the fluid reinforcement, or 5-100% by weight of the coarse filler, if any coarse fillers are present and are preferably about 10%.

As the material which can be applied to the reinforcing material before the reinforcing material is cured, any suitable short fiber or fine material such as flock or powder can be used. Short fibers or fine materials reduce the stickiness, increase the apparent thickness of the fabric, or give the fabric a soft touch.

The present invention will be described in detail with reference to the accompanying drawings.

The apparatus comprises a rollerstand 1, a feeder 2 for supplying the fabric to the rollerstand 1, and a heater 3 for use in curing the reinforcement material imprinted on the fabric.

The heater 3 is not shown in FIG. 1 and FIG. 2, but this heater 3 is shown in FIG. As shown in FIG. 1 and FIG. 2, the roller stand 1 fixes and supports the printing roller device, and the printing roller device is a printing member and a pressure applying roller 5 in the form of a rotary printing cylinder 4. It is formed of a supporting member. In order to drive the printing cylinder 4, a speed regulating drive motor 6 is provided. Examples of printing cylinders have a length of 60 cm and a diameter of 20 cm. The drive motor 6 is adjustable so that the maximum speed of the cylinder is 22 rpm, that is, a maximum main speed of 14 m per minute. For example, the printing cylinder 4 engraved in the printing cylinder 4 is engraved with a pattern of the hollow groove 7 (see FIG. 1) along the longitudinal direction, and the hollow groove 7 is a cylinder head. Serialized in full. When the entire length is to be printed (leave the smooth end), the groove should have a depth of 0.30 mm or 0.35 mm, the cross section being rectangular and having a width of 1 mm, with a gap of 1 mm between the grooves.

The pressure applying roller 5 is mounted on a movable fixing device in the form of two small bearings 8, the small bearings 8 are mounted on a transverse beam 9, and the transverse beam 9 is Guided by two guide sleeves 10, the vertical movement is strictly regulated. The guide sleeve 10 is active around the cylindrical guide cylinder 11 fixed to the transverse beam 9 and fixed to the roller stand 1.

The dual function pneumatic ram 12 is connected to the transverse beam 9 and on the one hand acts as a device to quickly lower the pressure applying roller 5 from the printing cylinder 4 and the pressure on the other hand. It acts as a device for returning the imparting roller 5 to the printing position. In order to limit the upward travel of the lateral beam 9 and the pressure applying roller 5, two adjustable joining members are provided. Therefore, when the roller spacing is required, such a joining member can be manually adjusted to lift the roller spacing in the range of 0.1 mm-0.4 mm or 0.5 mm.

The adjustable joining member may be of any suitable shape, but in the case of the device shown in the figure, it is in the form of a gear pinion 13, which is arranged on the top 14 of the threaded portion of each guide cylinder 11. It is threaded and stops with respect to the joining member 15 at the top of the guide sleeve 10. The gear pinion 16 also engages with each of the pinions 13. This gear pinion 16 is installed in the axial direction, but the axial lengths of the pinions 13 and 16 are such that each pinion stays engaged when the pinion 13 rotates up and down. .

Each pinion 16 is arranged on a vertical axis 17, and the two vertical axes 17 are joined by a horizontal axis 18 and two sets of bevel gears 19. The left shaft 17 (see FIG. 1) is connected to the manual wheel 20 by the bevel gear 21 and the short horizontal side 22. When the manual wheel 20 is rotated, the joining pinion 13 ), The guide cylinder 11 can be moved up and down. The pneumatic ram 12 may be connected to a manual controller or to an automatic controller that is activated when the fabric is passed through a roller stand. If the pneumatic ram 12 is connected to a manual controller, the operator must visually identify the area where the reinforcing material is printed. The device is such that when the transverse beam 9 is retracted there is a sufficiently large gap between the pressure applying roller 5 and the printing cylinder 4 so that the reinforcing material is not printed on the fabric.

The solution, emulsion or suspension of the reinforcing material is supplied to a reservoir 31 in which the conical wing 32 is held, and the reinforcing material is filled in the recess 7 engraved in the printing cylinder 4 by the conduit wing 32. Clean the area between the grooves. Although not required, a cover 33 can be installed on the printing cylinder 4, which cover 33 is used for cleaning the printing cylinder 4 at the time of shutdown (not shown). Can be submitted. Similarly, but not essential, the pressure roller 5 may be installed in the tub 34 of the cleaning liquid in order to continuously wash the pressure roller 5 during operation of the apparatus. In this case, the wiper blade 35 is extended to the pressure applying roller 5 so that any cleaning liquid attached to the pressure applying roller 5 can be removed.

The pressure applying roller 5 is driven from the printing cylinder 4 by the gear train 36, the gear train 36 being shown only a part of it in FIG. 2 and schematically shown in FIG. . Since the gear train 36 is installed so as to remain in the engaged sieve at all positions of the pressure applying roller 5, the pressure roller 5 can rotate even when it is lowered.

In FIG. 2, the feeder 2 is a stationary bed feeding table for hand passing fabrics, in particular cut pieces of fabric, and the small receiving table 41 is indicated in FIG. The fabric can be transported by hand and placed in the heater 3 in a suitable manner. However, for mass production, a feeder 2 is used as shown in FIG. 3, which feeder 2 is a conveyor belt type and the large bearing belt passes over the top of the pressure applying roller 5 and is pressurized. Driven by a roller. In addition, the conveyor belt passes through the washing bath (42). In this case, the belt covers the surface of the pressure applying roller 5, and when the pressure applying roller 5 is lifted up, this too is lifted by the pressure applying roller 5 as well. Installation of the bath 34 used to wipe the pressure applying roller 5 is not essential.

The device shown in FIGS. 2 and 3 is a device adapted to prevent the tendency of the fabric to stick to the printing cylinder 4. The four rollers 43 extend across the width of the printing cylinder 4, and the rollers 43 are filament just behind the position where the outer circumferential surface of the printing cylinder 4 is closest to the pressure applying roller 5. Guide the multiple looped filament material 44 through the printing cylinder 4 so that the material 44 is isolated from the surface of the printing cylinder 4 so that the fabric is isolated from the printing cylinder 4. There are four looped filament materials 44, the lateral position of which is held by the shallow annular recesses engraved in the roller 43. The filament material 44 is a nylon monofilament having a diameter of 0.12 mm, which has been found to not significantly damage the fabric even when the roller spacing is 0.1 mm.

The heater 3 is as shown in FIG. 3 in which the supply device 45 is provided, but the heater 3 can be used if it is a suitable form. For example, the heater 3 may be a simple radial heater, which heats the reinforcing material to 140-150 ° C. for 3-5 minutes. However, the reinforcement can be cured at lower or room temperature than this, and the dimensions of the heater 3 and thus the total heating time can be reduced to match. If the reinforcing material has curability that hardens itself at room temperature, it is preferable to combine the heating step to promote curing of the reinforcing material.

In Figures 4-6, the pattern of reinforcing material is larger than the piece of fabric itself.

4 shows the right rear panel 51 of the jacket reinforced by the apparatus shown in FIGS. 1 and 2. The panel was cut before being fed through the roller stand 1 and turned so that the blade direction of the panel was about 12 ° with respect to the length direction through the roller stand. When Panyl almost passed through the roller stand 1, the pressure bearing roller 5 was retracted but the pressure bearing roller 5 was briefly stopped to print the parallel lines 52 of the reinforcing material onto the collar of the panel 41. Parallel lines 52 lie at about 12 ° with respect to the string direction (indicated by reference numeral 53), but this angle can be increased to 30 ° if necessary. The parallel lines 52 printed on the collar are not intended to improve the feel of the fabric, but may improve the tensile properties of the fabric in this portion. Parallel lines 52 of the reinforcement material can be placed exactly parallel to the direction of the strings in the other pieces or the panyl, which is in the most conventional direction.

5 shows the sleeve 54 of the jacket, and the direction of the string is as indicated by the reference numeral 53. In this case, a line of reinforcing material is printed on the sleeves and extends almost parallel to the string direction 53. When the jacket is made or the sleeve length is increased or shortened, the fabric of the jacket is folded between the line 55 or the reinforcing material, which is then folded along the line 55.

Figure 5 also shows the case where the lines do not need to be continuous and their spacing does not have to be the same, especially in this case the fabric retains more natural flexibility. The discontinuities between the lines 55 are distributed such that the lines 55 are not arranged in any direction except that they are arranged in themselves. Employing this method results in a reinforcement having one strong orientation characteristic oriented parallel to the line 55.

6 shows the left front panel 56 of the jacket reinforced by the apparatus of FIGS. 1 and 2, wherein the panel 56 does not need to be cut in advance before feeding to the roller stands 1; The line of material 57 extends parallel to the string direction 53. If desired, a mask of a desired shape may be placed on the fabric to leave the portion 58 used to form the dart blank.

Fig. 7 shows a piece of fabric 59 used to make the breast pocket of the jacket, in which case it is folded by leaving a large blank strip corresponding to the fold line and the seam line using a mask of a predetermined shape. And sewing can be facilitated. Line 60 of the reinforcement material extends parallel to the string direction 53, and the plurality of pieces 59 may be printed with the reinforcement material before cutting the fabric. Two breast pockets of different sizes are sufficient for the overall size of the jacket.

8 shows a strip 60 of fabric used to make a pair of belts or belts of trousers, in which case the pattern of parallel lines 62 is printed along the length of the strip 61, and the spare 63 is blanked. In particular, the line 62 is preferably extended at about 45 ° with respect to the string direction 53. Orienting the lines in this way allows the bottom of the strip 61 to be distributed slightly more than the top (suitable to the waist), while slightly increasing the strength of the strip 61 in the longitudinal direction to prevent the top of the strip from crumpling. can do. Spacing 63 facilitates sewing and folding of the strip edge.

The pattern can be printed on the strip 61 in a number of ways. For example, the printing cylinder 4 as described above can be used. In this case, the strip 61 is turned at 45 ° with respect to the axis of the printing cylinder 4 and the excess 63 is masked. Alternatively, 45 ° with respect to the circumferential direction of the printing cylinder 4, depending on the total length of the printing cylinder 4 (when the mask should be used) or the length corresponding to the width of the pattern portion of the strip 61. You can print the line.

9 shows a pattern of reinforcing materials that can be used at specific locations. For example, such a pattern of reinforcing material may be used for the strip 61 instead of the parallel lines shown in FIG. 8, or may be used for the color strip of the jacket where special strength is required as the special strength is required. The parallel lines 64 are interconnected by the transversely extending portions 65 of the line 64, so that the portions 65 are not arranged in a line in any direction except that the lines 64 themselves are arranged. Distributed. Employing this method results in a reinforcement having one relatively strong orientation characteristic oriented parallel to the line 64.

Although the pattern of FIG. 9 can be engraved in the printing cylinder 4, the pattern can alternatively be printed on the fabric using a silk screen. In general, the reinforcement imparted to the fabric can be increased by increasing the width of the line in proportion to the width of the spacing of the lines, and in the special case of FIG. 9, the reinforcement is proportional to the length of the portion 65 It can also be increased by increasing (when measured parallel to line 64).

Example 2-13

In Example 2-13, the reinforcing materials used were the same as those used in Example 1, and the apparatus used those shown in FIGS. 2 and 2. All parts in the following table are given the weight unless otherwise indicated.

After supplying the liquid curable synthetic resin in the printing groove, the cylinder is continuously rotated, the hem cut according to the shape is passed through the cylinder, and when the specific part of the hem passes the cylinder, The two circumferential surfaces of the cylinder and the supporting cylinder rotated at the same time approach each other at regular intervals toward the hem, and the back of the hem is brought into contact with the printing cylinder to allow the curable resin in the printing groove to penetrate into the hem to a certain depth. And then harden the penetrated synthetic resin to localize specific areas of the hem. Which consists in that steel On the other hand, the printing of the above-described grooves are longitudinal reinforcing method of the fabric so that the whole reinforcement in one direction to prevent from being connected in the transverse direction or substantially connected to each other.
