Description

Gas forming pattern and its shape {SPLASHED PATTERN FORMING METHOD AND THE SHAPE}

TECHNICAL FIELD This invention relates to the gas-liquid formation method formed in a cloth by the several fine ridge | bulb set so as to point out a pattern or a pattern.

The gas pattern forming method is generally called "gas plate". According to the known technique of gassing, a part of the fabric which needs to form the ridges of the fabric is lifted for each part, and the raised end is bundled and set with a gaseous thread. Is formed. In this gasley technique, the lifting and binding of the gasseal thread in each part and the unwinding of the gasseal thread are performed by hand, which is inefficient and the price of the gasstripe fabric thus made is very expensive. do. Here, various methods have been proposed as to the method of efficiently performing the gas cooking. The main method is a method using a heat-shrinkable fiber as described in detail below.

In the first method, heat shrinkage with the heat-shrinkable gas-tight seal is obtained by sewing the heat-shrinkable gas-tight seal with a non-low heat-shrinkable fiber which is a work cloth and heating it to shrink the heat-shrinkable gas-tight seal. Iii) A method of forming a ridge according to a seam in a work stream due to a difference (Japanese Patent Laid-Open No. 60-252792, Japanese Patent Laid-Open No. 61-43475). The second method is a method in which a heat-shrinkable fiber is wrapped in a work cloth, sealed in a desired shape and heated to heat-shrink the heat-shrinkable fiber to form a ridge surrounded by the seam by the difference in shrinkage of the heat-shrinkable fiber in the work fabric ( Japanese Patent Application Laid-Open No. 60-252793, Japanese Patent Application Laid-Open No. 61-43476). In the third method, a ridge is formed according to the second method, but a water-soluble gaseous thread is used as the sewing thread, and the heat shrinkage is performed by solidifying the ridge formed in the work cloth and then dissolving the sewing thread. It is a method of peeling off and removing a sexual fiber (patent 3049058). In the fourth method, as in the second and third methods, the heat-shrinkable fibers and the work cloth are bonded to each other in a desired shape to generate ridges, but without using a sewing thread, an adhesive is applied in a desired shape instead of the sewing thread. It is a method of peeling and removing heat-shrinkable fibers by bonding fibers to non-low heat-shrinkable fibers to solidify the ridges generated in the work fabric and then dissolving the adhesive (Japanese Patent Laid-Open No. 6-240563, Patent No. 2554981).

In the first, second and third methods, the heat-shrinkable fibers are bonded to the sewing thread so that they are securely fixed to the work piece until the ridge is formed. However, it is difficult to apply it to the wide workpiece, because the special sewing sewing is necessary to make fine sewing when the part where the ridge is to be formed is the edge of the cloth. Takes In the fourth method, the adhesive may be applied in a desired shape with a gravure roll or a printing screen, and thus it can be applied to a wide workpiece. However, in order to do this, a dense heat-shrinkable fiber is required because the adhesive must be sufficiently applied so that it does not peel until the ridge is formed. Because of this, the heat-shrinkable fiber mesh can be easily peeled off due to adhesive adhesion even if a sufficient amount of adhesive is applied to the work cloth. Porous mesh is not used as a heat shrinkable fiber.

In this regard, in the second and third methods described above, the mesh can be used as a heat-shrinkable fiber because the mesh of the porous is reliably sewn to the work fabric with the sewing thread, and it is used when it is woven sparsely and is light in weight. Later, the treatment as waste also becomes easy. In the case of the second and third methods, the heat-shrinkable fiber is treated as a waste after use if it exhibits high heat shrinkage, so special properties other than heat shrinkage are not required. The cloth can be provided economically.

An object of the present invention is to economically provide a gaseous pattern fabric by bonding a heat-shrinkable mesh that is light in weight, inexpensive, and can be easily processed after use, with an adhesive to a workpiece fabric.

To get rid of it.

The third feature of the method for forming a gas grating pattern according to the present invention is that, in addition to the second feature, the joint material 16 before the bonding material 16 is placed on the heat shrinkable gas gypsum seal 11 · 12 constituting the heat shrinkable net 14. And the adhesive 17 is applied to one or both of the workpiece 15 to be processed.

(Example)

In the present invention, the term "non-low heat shrinkable fiber" means a fiber having a low heat shrinkage rate as compared with the heat shrinkable gas chamber seal 11 and 12 constituting the heat shrinkable network 14, and The heat shrinkage difference may be 20% or more at 100 ° C. The heat shrinkable net may be a woven fabric or a knit fabric, but in order to avoid that the difference in heat shrinkage between the heat shrinkable net 14 and the fabric 15 is substantially reduced by the structure of the heat shrinkable net 14, Because of the structure, it is preferable to make the heat-shrinkable network 14 into a woven fabric rather than a knitted fabric. As the bonding material 16, an adhesive film such as paper, plastic film, woven fabric, knitted fabric, nonwoven fabric, felt, fiber web, and the like is coated to form a continuous coating film in the form of a film. A sheet-like material that can be laminated is used, and these sheet-shaped materials may have a multilayered structure such as plastic film and paper, fiber web and fabric, plastic film and knitted fabric, for example. good. As the bonding material 16 of such a multilayered laminated structure, the plastic film may be a coating film formed by applying a resin composition to paper, fabric or knitted fabric, and the fiber web may be needle punching or water punching. Some fibers may be inserted into a fabric or knitted fabric by water punching (high pressure liquid flow), or may be laminated and temporarily bonded to a heat shrinkable net.

The bonding material 16 may form a tape with a narrow width. In this manner, as the tape-like bonding material, adhesive 17 may be applied and laminated in the same manner as in general office adhesive tape. Such a tape-shaped bonded material 16 is suitable for forming a gaseous pattern at one point on an extremely limited portion of the workpiece fabric 15 (Figs. 1 to 3). In the wide bonding material 16 in which the adhesive 17 is applied and laminated on the entire surface, the dissolving component and the swelling component of the adhesive 17, such as an organic solvent, water, an alkaline solution, and a plasticizer, are used. The melt-swellable paint containing the resin was pressed and wrapped in a work cloth 15 together with the heat-shrinkable net 14, left to stand for a predetermined time, and then released to a press roll. The bonding material 16 may be bonded to the workpiece 15 by passing through.

In the case where the heat-shrinkable net 14 and the joining material 16 are temporarily joined, a part 20 of the joining material 16 may be projected from the network gap 13 on the surface of the heat-shrinkable net 14 superimposed on the workpiece fabric 15. (Figure 4). In this case, as the joining material 16, a fibrous web in which short fibers or pulp fibers are deposited may be used. When the pulp fiber is used as the bonding material 16, it is placed on the heat shrinkable net 14, and when the short fiber web is used as the bonding material 16, it is laminated on the heat shrinkable net 14, and some fibers 20 are subjected to needle punching or water punching. Protrude from network gap 13.

In the gaseous pattern forming member 28 for temporarily joining the heat shrinkable net 14 and the joining material 16, the heat shrinkable net 14 contracts between the adhesive part 18 and the adhesive part 18 of the adhesive 17 when it is fixed and heated to the work cloth. Iv) the workpiece 15 is raised, and at this time, the joining material 16 is peeled off from the heat shrinkable net 14. For this reason, the joining material 16 does not interfere with the thermal contraction of the heat shrinkable net | shaft 14 between the adhesive site 18 and the adhesive site 18 (FIGS. 5-6).

In the present invention, the peel strength between the heat-shrinkable network 14 and the bonding material 16 is less than 50 gf / 2.5 cm. As described above, the bonding material 16 is a heat-shrinkable network between the bonding site 18 and the bonding site 18. This is to prevent the fabric 15 from being protruded by being peeled off from the 14 so as not to interfere with the heat shrink of the heat shrinkable net 14. In other words, the peel strength between the heat shrinkable net 14 and the joining material 16 is so weak that the heat shrinkable net 14 and the joining material 16 do not peel before the gaseous pattern forming member 28 is joined to the workpiece fabric 15.

In the gaseous pattern forming member 28 which protrudes some fibers 20 of the pulp fibers and the fibrous web (bonding material 16) from the mesh gap 13 by thin or flat bonding without using an adhesive or by needle punching, the protruding fibers 20 Even if it is peeled out from this network gap 13 and a thick heat-shrinkable gas-liquid chamber 11 and 12 is used, between the heat-shrinkable gas-liquid chamber 11 (12) and the heat-shrinkable gas-liquid chamber 11 (12) (network gap 13) It is filled with the protruding fiber bloat 20 so that the adhesive surface with the workpiece fabric 15 is flat and the protruding fiber bloat 20 exhibits an anchoring effect. Therefore, a normal gravure roll or printing screen is used. When the adhesive 17 to be applied in the desired shape is securely adhered to the gaseous pattern forming member 28 and the fabric to be processed 15, even with a thin coating film. Can kill.

The adhesive 17 may be applied by pressing a gravure roll or a printing screen to any of the workpiece fabric 15, the gaseous pattern forming member 28 or the bonding material 16. However, the bonding material 16, which is applied by pressing the adhesive 17, is sandwiched in the work fabric 15 with the heat-shrinkable net 14 in the middle, and the bonding material 16 is made of a plastic film. , Knitted fabrics, nonwoven fabrics, felts), when the plastic film is laminated on the coated and coated surface of the adhesive 17, the compressed adhesive 17 is not absorbed into the bonding material 16, and the amount of the adhesive 17 is small. Even in this case, the heat shrinkable net 14 can be reliably bonded to the workpiece fabric 15. Particularly, when the fabric 15 has swelling or irregularities and it is difficult to compress and apply the adhesive 17, or when the fabric 15 is rich in absorbency and hygroscopicity, the plastic film is used as the bonding material 16. Alternatively, it is recommended to apply adhesive 17 to the plastic film surface by using a bonding material 16 in which a plastic film is laminated.

In the present invention, the space N between the gaps 13 of the network gaps is equal to or more than twice the apparent thickness M of the heat-shrinkable gas chamber seals 11 and 12. This is because they are press-fitted into the net gap 13 and adhered to each other when the heat-shrinkable net 14 is bonded and bonded therebetween, so that the adhesive film 17 is reliably adhered even if it is thin. In this way, in order to make the workpiece fabric 15 and the joining material 16 close to each other in the network gap 13, the heat-shrinkable gas chamber seals 11 and 12 are made of multi filament yarn, and the heat-shrinkable network 14 has a weight of 20 gf / m ^2. It is thin and very thin below. In order to make the heat shrinkable net 14 very thin, the heat shrinkable gaseous yarn 11/12 may be formed into a flat cross section by passing it through a paper emboss roll.

Thus, even if the heat shrinkable net 14 is flat and very thin, the work piece 15 is contracted by the heat shrinkable gas-shrink yarn 11 · 12 to form a ridge 19, and if this is flat, the heat shrink is widened. Thus, the gaseous chamber 11 (12) and the gaseous chamber 11 (12) are easy to access, and the network 14, which is used to form the gaseous pattern and heat-shrink, is not a part of the gaseous pattern fabric, but is treated as waste, so there is no problem. It does not occur On the contrary, if the heat shrinkable net 14 is thin and very thin, it can be obtained inexpensively, and the treatment as waste becomes easy. However, if the heat shrinkable net 14 is too sparse and the net gap 13 is widened, the heat shrinkable gaseous thread 11 · 12 intersecting at the application site of the adhesive 17 cannot be fixed to the workpiece fabric 15 at the same time, and the ridge 19 will not be dense. It becomes difficult to form complicated and delicate gas pattern. In view of these circumstances, the heat-shrinkable gaseous yarn 11 · 12 is a fine filament of 200 dtex or less, preferably 100 dtex or less of multifilament yarns, and the space between adjacent heat-shrinkable gaseous yarn 11 · 11 (12 · 12) N is 7 mm or less, Preferably it is 0.5-4 mm, More preferably, it is set to 1-2 mm.

Fig. 7 shows a specific example of the process for forming a gaseous pattern, in which thermoplastic synthetic fibers are used as the work fabric 15. The adhesive 17 is pressed onto the bonding material 16 by gravure roll 21 and applied. The joining material 16 is sandwiched in the workpiece fabric 15 with the heat-shrinkable net 14 in the middle and passed through the press roll 22. At this time, the work fabric 15 and the joining material 16 are brought into close contact with each other in the network gap 13 of the heat shrinkable network 14, and the adhesive 17 is solidified through the drying zone 23. At this time, the heat-shrinkable gas chamber seal 11 and 12 is joined. The heat shrinkable net 14 is bonded to the workpiece 15 by being wrapped in 16. Subsequently, the heat shrinkable net 14 contracts through the heating zone 24, whereupon 19 is formed in the work stream 15, and at the same time, the uplift 19 is solidified by heat. After that, the adhesive 17 is swelled and dissolved by the treatment liquid 25, and the heat shrinkable net 14 and the bonding material 16 are separated from the workpiece 15, and only the workpiece 15 is washed with the treatment liquid 26. It is then taken out through a dry area 27.

In the specific example shown in Fig. 7, the heating zone 24 is heated above the softening temperature of the thermoplastic synthetic fiber, which is the workpiece 15, and the ridge 19 is solidified by heat, but the solidification of the ridge 19 is not caused by heat. ), Or by adding chemicals to solidify by changing the molecular structure of the fibers constituting the workpiece fabric 15.

As described above, in the present invention, the heat-shrinkable gaseous thread 11 · 12 constituting the heat-shrinkable net 14 is sewn with a sewing thread, instead of directly bonding the heat-shrinkable net 14 to the workpiece fabric 15 with an adhesive 17, or a U-shaped nail. Bonding material 16 which passes through the heat-shrinkable gas chamber seals 11 and 12 and is coated is bonded to the workpiece fabric 15, and the bonding material 16 is sandwiched between the heat-shrinkable nets 14 at the adhesive portion 18 of the adhesive 17. To the workpiece 15. That is, since the bonding material 16, which is a medium for fixing the heat shrinkable net 14 to the workpiece fabric 15, is used, the adhesive 17 is not applied to the heat shrinkable net 14, but it can be applied even if it can be applied. Even if it is a flat fabric which is easily peeled off, the heat-shrinkable network 14 can be reliably bonded to the work fabric 15.

And although the heat shrinkable net 14 is thin and very thin, the workpiece 15 is contracted together by heat shrinkable gas-sparing yarns 11 and 12 to form a ridge 19, and the heat shrinkable net 14 is thin and the net gap 13 is formed. When the gas shrinkage chamber 11 (12) and the gaseous seal 11 (12) which heat become wide are easy to access, high elevation 19 is easy to form, and the heat shrinking net 14 used for formation of a gaseous pattern is a part of a gaseous pattern cloth. The heat shrinkable net 14 does not cause any problem because the heat shrinkable net 14 is only a shape for forming a desired pattern on the fabric to be processed, but rather, the heat shrinkable net 14 is thin and very thin. It can be obtained inexpensively, and if the heat shrinkable net 14 is thin and very thin, The disposal as waste after use is also simplified. As described above, according to the present invention, a gaseous pattern cloth can be provided efficiently and economically.
