Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing twisted yarn for textiles.

(Prior Art) Twisted yarn for textiles is manufactured by pliing together a plurality of twisted yarns (4 to 9 raw silks for Oshima Tsumugi twisted yarn) and twisting them.

Here, the manufacturing process of the textile twisted yarn used for Oshima Tsumugi will be explained in detail.

As shown in Fig. 4, first, raw silk 4 (single thread taken from the cocoon of a silkworm and not touched) is wound around a bobbin (repeated step A)), and the bobbin 3 wrapped with this raw silk is wrapped around a bobbin. 4
Arrange ~9 pieces in the longitudinal direction (see Figure 1), each thread t! The raw silk 4 is pulled downward from 3, and then the raw silk 4 is doubled (step B) and twisted (step 12!i yarn (C)) to produce one twisted yarn. This twisted thread is refined
(D) step - immersing the yarn in a hot water bath at about 90° C. containing industrial soap for about 2 hours) to remove sericin forming the surface of the twisted yarn and soften the twisted yarn. Here, the twisted yarn is dyed in any color and dried (dying step (E)).

What is noteworthy about the above-mentioned conventional techniques is that raw silk is combined and twisted and then dyed (colored) to produce twisted yarn for textiles.

(Problem to be solved by the invention) However, in such twisted yarns for textiles, each twisted yarn can only be dyed in one color, so when producing textiles by combining these twisted yarns, it is necessary to dye finely colored yarns. There is a problem in that it is not possible to weave a complex and deep-colored fabric by combining them.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems, and as a means thereof, a plurality of twisted yarn constituent yarns are combined and twisted before twisting. It is designed to be colored.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The figure is a perspective view showing the structure of the twisted yarn, FIG. 3 is a manufacturing process diagram of the twisted yarn for textiles according to the present invention, and FIG. 4 is a diagram of the manufacturing process of the conventional twisted yarn for textiles.

In this example, a twisted yarn for Oshima Tsumugi using raw silk will be explained. Reference numeral 1 shown in FIG. 2 indicates a twisted yarn for Oshima Tsumugi.This twisted yarn 1 is made by piling together eight pieces of raw silk 1a and then twisting them.

Hereinafter, the manufacturing process of the twisted yarn 1 will be explained in detail.

As shown in Figure 3, first, a plurality of raw silks 1a (single threads taken from silkworm cocoons and unaltered) are scoured (scouring (F+) process - a hot water bath at about 90°C containing industrial soap, etc.). The raw silk 1a is softened by removing sericin constituting the surface of the raw silk 1a.

Next, the plurality of raw silks 1a are separately dyed in various colors and dried (dying (G) step) (drying (H) step), and the dried raw silks 1a are wound around threads for each color (repeatedly. )
(Step), eight threads S3 are arbitrarily selected from the spools around which raw silk 1a of various colors are wound, and arranged in the longitudinal direction on the thread twisting machine 2 (see Fig. 1).

Thereafter, the raw silk 1a is pulled downward from each spool 3, and the raw silk 1a is combined there.The raw silk 1a is then twisted (combined yarn U) step) and twisted (twisted yarn (K) step) to produce one twisted yarn 1.

According to this method, since the twisted yarn 1 is manufactured by combining raw silk 1a of eight different colors, the twisted yarn 1 can be finished in a complex and deep color.

The difference between the above embodiment and the prior art is that in this embodiment, when producing the twisted yarn 1, the raw silk 1a is first dyed and then the yarn is combined and twisted.

In this example, eight raw silks 1a are combined and twisted to make one twisted yarn 1, but the number is not limited to eight, and any number of yarns may be used depending on the application. The single yarn is first dyed and then combined and twisted, but first two (not limited to two, but two to several) raw silk 1a are combined and twisted, then dyed and then combined. A twisted yarn 1 finally made of eight raw silks 1a may be produced.

(Effects of the Invention) As described above, the present invention produces a single twisted yarn by combining and twisting a plurality of twisted yarns dyed in several colors, so fabrics are produced by combining these twisted yarns. It has the excellent effect of being able to create a more complex and deeper color on the fabric than before.
