Description

[Detailed description of the invention] The present invention relates to a method for patterning a woven surface.

More specifically, the dye is applied as a medium to a sheet made of single fibers or filaments of heat-softening synthetic fibers and formed into an irregular mesh thin enough to be seen through, or a web made into a sheet by a dry method. This invention relates to a patterning method for forming a pattern on a woven surface by thermocompression bonding to the woven surface. All kinds of woven surfaces can be used as adherends to be patterned in the method of the invention. That is, as the woven surface, all kinds of woven fabrics such as cotton, silk, synthetic fibers, or in special cases, woven fabrics in which metal foil, metal tape, or paper tape is added and woven in the form of threads are used as the adherend, and patterns are applied to this. It is possible to attach. The basic idea of the patterning method of the present invention is that the dye is heated to a sheet made of monofilament fibers or filaments made of softenable synthetic fibers and combed into an irregular net shape, or a sheet is formed by a dry method. After impregnating a web (hereinafter collectively referred to as a mesh sheet) with a dye solution, or coloring the mesh sheet with the dye solution, or drawing a colored pattern on it, at least drain or dry it. Then, superimpose this at the desired position on the surface to be adhered, layer release paper on top of it, and apply the desired coloring or coloring pattern dye through the release paper to an irregular net-like sheet of heat-softening synthetic fibers. The present invention also relates to a method for patterning a woven surface that is thermocompression bonded to a woven surface.

That is, a dye is once colored and adsorbed in a single color or in a desired pattern on an irregular mesh sheet of heat-softening synthetic fibers, and then the mesh sheet is used as a medium and is thermocompressed onto the woven surface for coloring or patterning. be. 0 The invention will be explained in detail below.

The heat-softening synthetic fibers used in the present invention include polyamide-based synthetic fibers such as nylon, polyvinyl chloride-based, polyvinylidene chloride-based, polystyrene, polyacrylonitrile-based, polyvinyl alcohol 5-based and co-monomers of these. A filament that is a single fiber, a fiber, or a long fiber is used, and those having a melting point in the range of 120 to 200°C are preferably used.

If the temperature gets too high, the dye used will deteriorate and should not be used. The white or colorless single fibers, fibers, or filaments of these heat-softening synthetic fibers are rolled up like paper to make them thin enough to be seen through, and then made into an irregular net shape. Strain and dry. In this case, carboxymethylcellulose, polyvinyl alcohol, or aqueous solution of molasses is used as the sizing agent. The material filtered in this way can be made into sheets of various thicknesses and thicknesses with varying amounts of voids by adjusting the concentration of single fibers, fibers, or filaments in the dispersed liquid. It will be done. In this case, if the pattern is to be formed from the net-like sheet of heat-softening synthetic fibers from the beginning, a water-soluble adhesive, such as carboxymethyl cellulose or polyvinyl alcohol, is applied to the film in advance to form the desired pattern. In some cases, the patterns are preconfigured by gluing the net-like sheets together or by skiving them together.

In addition, such irregular net-like sheets of heat-softened synthetic fibers are produced by heat-melting them using webs that are scraped from the fibers during the spinning process and have a web shape that is deep enough to be seen through. It can also be manufactured by a method in which a nonwoven fabric is produced by spraying a dispersion of vinyl acetate, polyvinyl alcohol, etc. as an adhesive onto these webs and fixing them.

Figures 1 and 2 show a plan view and a cross-sectional view of the irregular reticulated sheet produced in this way.
As seen in this, the single fibers, fibers or filaments are simply twisted and bonded in an irregular manner, and there is no need for knitting.

Irregular mesh sheets of thermoplastic synthetic fibers thin enough to be seen through can be used as heat-pressing adhesives for textiles, and those made of polyamide or nylon, for example, can be used as belt core adhesives for non-woven fabrics for belt cores. Along with Vilene (V
It is manufactured by Nippon Vilene Co., Ltd. under the trade name of M-1, and can be used as is in the present invention. Next, the dye used in the present invention is adsorbed to the single fiber, fiber, or filament when it is dyed or printed, even if the heat-softening synthetic fiber used is not specifically dyed. Any material can be used as long as it is crimped together with the synthetic fibers on the fabric that is the garment.

Normally, when dyeing woven fabrics, it is necessary to select the type of dye depending on the material, such as cotton, silk, nylon, vinylon, polyvinyl chloride, etc., but in the present invention, the dye used is It suffices if the material is adsorbed onto an irregular reticulated sheet of heat-softening synthetic fibers and pressed onto an adherend, and a particularly close affinity is not required. However, before use, it is sufficient to simply test the adsorption to the reticulated sheet and the adhesion to the adherend, and strict selectivity as in dyeing is not required. However, when fastness is an issue, for example when nylon is used as the heat-softening synthetic fiber and silk fabric is used as the adherend, it goes without saying that acidic dyes that are compatible with both are particularly preferred. Nor. Normally (1. For example, when using water-soluble dyes, unless the synthetic fibers used are water-repellent, and the dyes used do not change at temperatures around 200℃, direct dyes, acid dyes, acid mordant dyes, basic dye,
All types of dyes such as sulfur dyes, vat dyes, soluble vat dyes, naphthol dyes, oxidation dyes, and synthetic fibers can be used, and dyes that are not natural dyes, such as mordant dyes, can be dissolved in a solvent for coloring. can be used. Next, in order to color an irregular reticulated sheet of synthetic fibers using method 6 of the present invention, as mentioned above, the adhesion of the coloring dye to the reticulated sheet and the adherend is determined. This is carried out after testing, but as mentioned earlier, a particular level of affinity for dyeing is not required, so most dyes and pigments are made into a solution of the required concentration and the reticulated sheet is impregnated with it or used. The net-like sheet is colored in the desired color or colorant-like manner using a dye solution or several kinds of dye liquids of the desired coloring.

At this time, it is also possible to print in a desired color or colored pattern using an appropriate paper pattern. In this way, the desired coloring or coloring pattern has been completed. The U-shaped mesh sheet can be used immediately after printing. Once impregnated, it can be used after being drained to the extent that the liquid does not drip when placed on paper, but it is usually used by drying it to the extent that the color does not adhere to other surfaces. Further, the target woven fabric 11 which is the adherend of the present invention does not necessarily have to be a base material, but may already be a lightly colored material such as white, yellow, blue, green, etc.
Even if various patterns have already been applied, it is possible to color over them, which has the effect of making the existing patterns stand out.

In special cases, the aesthetic sense can be significantly improved by coloring only the raised parts, such as extruded fabrics, so it is possible to use the whole part as an adherend unless it has severe irregularities. can. A thermocompression bonding method is used to transfer the irregular reticulated sheet of the present invention already colored in a desired color or pattern onto an adherend to color or pattern the adherend.

That is, the irregular mesh sheet of the present invention colored in the desired color or pattern is placed on the desired position of the adherend, for example, the fabric to be colored, and a heat-resistant release paper is placed on top of it. The mold surface is placed facing the mesh sheet, and thermocompression bonding is applied thereon by an appropriate method.The heat bonding method is a conventional method, for example, an electric iron, a steam iron, or a combination of steam heating and pressing. The temperature at that time 1 As mentioned earlier, it depends on the type of thermoplastic synthetic fiber that is the medium, and it is sufficient to use a temperature above the softening point of the synthetic fiber, but the upper limit is Care must be taken to ensure that the temperature does not exceed the temperature at which the dye or pigment used and the adherend will deteriorate, and usually
For example, the polyamide compound Vilene double-sided adhesive core Vilene M-1 or F
4. Use a steam iron at a temperature of 150-160℃.
You only need to press it for ~5 seconds, and if you want to increase the number of mesh sheets to transfer coloring with fewer gaps, you can stack multiple mesh sheets, and the heating and pressing time depends on the number of sheets. Just increase it. After pressing, if you gently peel off the release paper, the coloring will be completely transferred to the adherend along with the net-like material. Figure 3 shows a silk belt colored in an irregular net shape in this way. In this case, if the net-like sheet is cut into the desired shape in advance and bonded under heat, the desired color and pattern will be transferred at the same time.Also, a paper pattern cut out in the desired shape following the printing pattern can be attached to the net-like sheet and the adherend. Even if thermocompression bonding is performed between the two, the desired color and pattern will be transferred at the same time. FIG. 4 shows an example of this. After the coloring or pattern is transferred to the adherend in this way, there is no need for a special finishing process such as that used for dyeing, but only if the adherend has an affinity for the dye used, such as a woven fabric that can be dyed. It is better to finish by steaming and washing with water to fix the stain. As described above, the method of the present invention does not require a special scouring and bleaching process unlike the dyeing of textiles, does not require consideration of strict compatibility between dyes and fabrics, and can be carried out very simply and in a short time. It has become possible to pattern an adherend with a desired color or coloring pattern.

Furthermore, according to the method of the present invention, extremely excellent coloring or patterning can be achieved without causing pollution problems such as disposal of dyeing washing water, etc., as in the case of dyeing.
