【発明の詳細な説明】 この発明は野蚕糸の品質改良法、特１ｃ濃染力を向上し
た野蚕糸を得る加工法に係わるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for improving the quality of wild silk yarn, particularly a processing method for obtaining wild silk yarn with improved 1c deep dyeing power.

絹といわれるものには通常、家蚕のつくったまゆをほぐ
して取ったものと、山野で自然忙成育した野蚕のつくっ
たまゆからとったものとあり、野蚕糸には更にさく蚕糸
、天蚕糸、その他幾つかの野蚕糸があるが、前の三者が
よく利用されている。There are two types of silk: those made by loosening the cocoons made by domestic silkworms, and those made from the cocoons made by wild silkworms that grew naturally in the mountains and fields. There are several other wild silk threads, but the first three are the most commonly used.

いうオ０用上、極めて不利な問題をかかえている。! f'i/f'i is made from sericin and fibroin, just like domestic silk thread. Perhaps due to the difference in the diet of wild silkworms, it contains brown pigments (carotene, etc.), fat, wax, tannins, uric acid, etc. They not only cover the surface of the fiber, but are also included inside the fiber, and the eyebrows themselves are thick and coarse, and have strength, elongation, and chemical properties. However, since it has a so-called vulgar luster and is not easy to spin, it is subject to relatively strong operating conditions at the reeling stage, and for this reason, when it is used to its full potential. There are problems such as shrinkage, and in addition, it is difficult to dye the axial line, dark and white, and it is particularly difficult to dye deeply, which is an extremely disadvantageous problem in terms of printing.

これらの不都合な点があるため、野蚕糸は家蚕糸にくら
べ、５０％位の価格にもかかわらず、実際に使用される
ことが少なかった。Due to these disadvantages, wild silk silk is rarely used, even though it is about 50% cheaper than domestic silk silk.

このような背撰にかんがみ、禾発明者は野蚕糸の欠点を
なくす研究を重ね、本発明に到達した。本発明は野蚕糸
の染色性を改良し、防縮性を有する剪蚕糸を得る加工法
を提供することな目的とするものである。In view of such back selection, the inventor conducted repeated research to eliminate the drawbacks of wild silk thread, and arrived at the present invention. An object of the present invention is to provide a processing method for improving the dyeability of wild silk thread and obtaining shredded silk thread having shrink-proof properties.

以下本発明の詳細な説明する。The present invention will be explained in detail below.

クラフト加工さセる方法である。The present invention is based on the following general formula (1) % formula % () (in the formula, R1 is hydrogen or a methyl group, R2 is 01 to CI
A derivative of acrylic acid or methacrylic acid represented by an alkyl group or aryl group of B (representing the number of n+-1, 2 to 2o) is added to wild silk thread,
This is a method of craft processing.

出された値を示している。The compound of formula (I) above consists of acrylic acid or methacrylic acid and polyethylene glycol monoalkyl (or aryl)
Obtained by reaction with ether. General formula (1) above
Those with rl of 4 or more are usually synthesized by the above synthesis reaction with a mixture of several of those with n values close to each other.
Since there is no need to separate this into the glaze, it can be used as is. Therefore, when displaying the compound of the general formula (I) described later, when the value of n is 4 or more, the value calculated from the average molecular weight is shown.

がよくなる。ｎが４以上になると臭気はほとんどない。The compound of the above general formula (1) used in the present invention, ie, those where n is 2 or more -J=, has an increased affinity with water, and wild silk thread can be processed extremely well. Compounds n or 1 are insoluble in water, and a large amount of emulsifier (to 7mer 10
% or more) as a membership fee, and if the emulsification property is poor, uneven processing,
This causes drawbacks such as hardening of the product and M6 eraser Z. In particular, if the liquid 11A is reduced in size and processed in 4b with the addition of Obermeyer t1ρ, trouble or W1 will occur. However, all the compounds (1) used in the present invention have a strong affinity with water, and can be processed in a water-containing container with very little emulsifier or without any necessary costs. Even when processed using an Obermeyer-type processing machine with a small liquid handle, there is no uneven processing.
As D in the above general formula (I) increases, a processed yarn with a softer texture and less shrinkage is produced, and as n increases, the odor of the compound itself disappears, improving the working environment. When n is 4 or more, there is almost no odor.

後は効果の増大はみられない、。It becomes darker as the color increases. The effect becomes more pronounced as the weight increase rate increases up to about 40 inches, but no increase in effect is seen after that.

わが同じときには、上記一般式（ｒ）におけるアルキル
基の炭素数の多い方が濃染効果を示すが、炭素数が４以
上になると差が殆んどなくなる。In the same case, the alkyl group in the above general formula (r) with a larger number of carbon atoms exhibits a deeper dyeing effect, but when the number of carbon atoms is 4 or more, the difference almost disappears.

んど起らないので濃染効果は覗、ゎれない。As the number of n in general formula (I) increases, the effect of deep dyeing becomes more pronounced, with n = 9 or so showing the most effective effect, and thereafter even as n becomes larger, the effect gradually becomes more pronounced than that of n = 9. decreases. This is also thought to be because the ratio of 1-female aqueous becomes too high, resulting in a decrease in the graft i ratio, and the grafting process is not performed on the wild silk thread. When n reaches 26th place, almost no increase occurs, so the effect of deep dyeing cannot be seen.

In addition, when the fibers used in the conventional grafting process are treated with other vinyl monomers such as 2-hydroxyethyl methacrylate, 2-hydroxysolol methacrylate, methacrylamide, and hestyrene, Staining is lower than that of the untreated]-system. However, if the monomer of this invention is copolymerized with the monomer of the $-invention and grafted, and at that time, the monomer of the invention is added to the fiber in an amount of about 10% or more, a deep dyeing effect can be obtained. It appears and is dyed darker than raw yarn.

First, a radical polymerization catalyst is added. Examples of catalysts include organic and inorganic peroxides such as persulfates, persates, hydrogen peroxide, benzoyl peroxide, and di-t-butyl/meroxide; ,
A redox catalyst or an azo compound made by combining a reducing substance a such as an amine compound can be used.

℃, and process the wild silk thread at that temperature for 60 to 90 minutes. Catalysts, pH adjusters, and emulsifiers use 1 liter of monomer.
Depending on the knowledge of the aqueous cicada body, it may be carried out according to the conventionally known silk grafting method, and if it is insufficient, it may be added.

In the case of Obermeyer-type processing machines, the difference between hydrophilic monomers and poorly water-soluble monomers becomes noticeable. The wild silk thread to be processed may be a thread or a secondary product thereof (for example, a woven fabric). When grafting a woven fabric, it may be sandwiched as described above, or the woven fabric may be placed in a processing bath. You can soak it to remove monomers, particles, etc., then take it out and steam it.
