Description

[Detailed description of the invention] Synthetic resin film pongee threads are used as pattern warps, picture wefts, sewing threads, and decorative threads, and different color dyed patterns are created by back beam processing using the difference in dyeability from ground silk threads. Although it has been often used to express this, synthetic resin film pongee thread not only is too shiny and stiff and spoils the texture of silk, but it cannot be strictly called a 100% silk fabric. It was treated as a cheap item.

The present invention applies a polyester resin coating layer to the outer surface of silk thread, and utilizes the difference in dyeability between this polyester resin coating layer and silk thread to express a different color dyeing pattern through piece dyeing. A method for manufacturing piece-dyed silk fabric that does not use synthetic resin film pongee yarn, is made of 100% silk, does not impair the soft texture of the silk fabric, and can easily express beautiful piece-dyed patterns, so that it can be treated as high-quality kimono. A polyester resin solution dissolved in a solvent is applied to the outer surface of the silk thread by an appropriate method to form a processed silk thread whose outer surface is coated with a polyester resin coating layer, and this processed silk thread can be used for various types of silk. It is woven into textiles as pattern warps, picture wefts, sewing threads, and decorative threads, and takes advantage of the difference in dyeability between silk and polyester resin to prevent contamination of the ground silk thread when dyeing this processed silk thread, and dyes the ground silk. and expresses a unique beam pattern. Further, a polyester resin coating layer is formed on the outer surface of the scoured silk thread, unscoured silk thread is used as the ground silk thread, and the processed silk thread is dyed and then the woven fabric is scoured.

Also dissolve the polyester resin using a volatile solvent,
A conventional warp sizing method is employed to form a polyester resin coating layer on the outer surface of the silk thread. It is also characterized by the use of processed silk yarn for the picture weft of the double-sided silk fabric, which has different weave patterns on the front and back sides. The 100% silk fabric, which expresses the background pattern by changing the conventional texture, can be processed with a back beam to create a diamond design on the base that reads ``Ji Minato Kaoru Sky Proverbs Cloud Tomb''; there were.

For this reason, there are some yarn-dyed fabrics that use yarn-dyed silk yarn that has been pre-crossed to create a unique color in the background pattern, but compared to piece-dyed fabrics, the various operations are much more troublesome, and the yarn-dyed silk yarn is It has the disadvantage that it cannot express gorgeous patterns like .

Therefore, synthetic resin film paper cut threads with different dyeability are used for pattern warp threads, picture striped threads, sewing threads, decorative threads, etc., and the patterned parts where many of these synthetic resin film cut threads are exposed on the surface are piece-dyed. The soil is dyed in a different color from the color of the ground part, and the soil contamination is washed off during post-processing such as scouring and washing using the difference in dyeability between the synthetic resin film pongee thread and silk thread to create a different color dyed pattern. Post-dyed silk fabrics are often used to express this effect, but the synthetic resin film pongee yarn has a square cross-sectional shape, making it stiff and stiff.
The soft texture unique to silk is lost, and strictly speaking, it is silk 10
It could no longer be considered a 0% silk fabric, and it had the disadvantage of being treated as a cheap item.

The present applicant focused on this point, and as a result of various studies, it was found that a silk fabric that does not use shredded synthetic resin film yarn does not spoil the soft texture of all silk, but uses shredded synthetic resin film yarn. In the same way, by utilizing the difference in dyeability from silk, it became possible to produce piece-dyed silk fabrics that could express different colored dyed patterns through back-beam processing.

In the present invention, a synthetic resin solution, such as a polyester resin solution dissolved in a solvent, which has different dyeability from silk threads and which does not damage silk threads during the dyeing process, is applied to the outer surface of silk thread 1 by an appropriate method to form a polyester resin coating layer. A processed silk thread 3 whose outer surface is coated is formed in step 2, and this processed silk thread 3 is woven into various silk fabrics as pattern warp, picture weft, sewing thread, or decorative thread.However, this processed silk thread 3 is actually silk thread 1. However, since a polyester resin coating layer is formed on the outer surface of the processed silk thread 3, its dyeability differs from that of a simple plain silk thread 4 due to the presence of the polyester resin coating layer 2. This means that the dye used to dye the processed silk thread 3 will not dye the ground silk thread 1.

Therefore, when the processed silk thread 3 is dyed to a desired color by piece dyeing, the base silk thread 4 is also contaminated with that color, but this contamination can be easily washed off during subsequent post-dying, so the processed silk thread 3 is exposed. It is extremely easy to express the different-colored beam pattern 5 by post-dying the patterned part in a color different from the ground because it does not necessarily cause contamination of the ground.

This polyester resin solution is applied extremely thinly to the outer surface of the silk thread 1, and the cross-sectional shape of the processed silk thread 3 is not rectangular like conventional synthetic resin film shredded threads, but is the same as the silk thread 1, so it is a patterned warp or a striped thread. A high-quality silk fabric made entirely of 100% silk, which does not stiffen the texture and lose the unique softness of silk even when woven into it as sewing thread or decorative thread, unlike when using conventional synthetic resin film shredded thread. will be treated as such.

As described above, the present invention has the excellent feature that it is extremely easy to piece-dye the unique color dyeing pattern 5 even though it is a high-quality product made of 100% silk. It can be used for interior textiles and various other textiles.

Furthermore, since a volatile solvent is used to dissolve the polyester resin, when this polyester resin liquid is applied to the silk thread 1, the volatile solvent evaporates immediately, making it possible to apply each thinly and making the application process easier.

Furthermore, if the polyester resin liquid is applied to the silk thread 1, the silk thread 1 coated with the polyester resin liquid cannot be scoured, but in this invention, the polyester resin liquid is applied to the scoured silk thread 1, and the silk thread 1 coated with the polyester resin liquid is coated with the polyester resin liquid. Since the silk is then refined, the resulting silk fabric is made entirely of 100% refined silk, and the soft texture unique to silk fabric is not lost. In addition, since the polyester resin liquid is applied to the silk thread 1 which has been refined by the conventional warp sizing method, the polyester resin liquid can be applied thinly and evenly over the whole silk thread 1, and the silk thread 1 and the polyester resin liquid can be applied to the entire silk thread 1 completely. The dyeing effect due to the difference in dyeability from the resin coating layer 2 can be reliably exhibited.

Next, one embodiment of the present invention will be described in detail. Dissolve the polyester resin using a volatile solvent such as toluene.

The degree of dissolution and dilution is preferably about 5 parts of toluene per 50 parts of the polyester resin solution.

A diluted polyester resin solution is applied to the outer surface of the refined silk thread 1 using a conventional warp sizing method.

Since the drying process is a volatile solvent, it is quickly dried by blowing air at room temperature, and a processed silk thread 3 coated with a polyester resin coating layer 2 is formed. This processed yarn 3 is used as a picture-striped yarn and woven with unscoured ground/warp silk yarn to weave a double-sided silk fabric with different weave patterns on the front and back sides.

A large amount of the processed silk thread 3 is exposed on the surface of the ground pattern portions on the front and back sides, and the processed silk thread 3 is embedded inside other than the ground pattern portion.

The processed silk thread 3 exposed on the surface is dyed by a conventional carrier beam method, and then high pressure steamed by a conventional method to complete the dyeing.

This post-dyed fabric is refined, and the ground is further dyed in a different color from the ground pattern part by overlaying, resulting in a back-liang silk fabric in which a different color dyed pattern 5 is expressed in the desired ground color.
