(Prior Art) Various methods have been used to date to improve the practical performance of silk, which has a drawback of wrinkle resistance when wet, by applying graft processing to silk. Most of them are processing methods in which a mono-vinyl compound containing one methacrylic acid ester group is added to the molecule and graft polymerized in silk fibers.

(Problems to be Solved by the Invention) In order to achieve effective modification of wet wrinkle resistance by processing with the mono-vinyl compound, it is generally about 25 to 40% of that of unprocessed silk. It is necessary to achieve a high polymerization adhesion rate. For this reason, there was a problem in that the characteristics inherent to silk, such as feel, whiteness, texture, flexibility, hygroscopicity, and dyeability, were lost.

In order to significantly improve the wet wrinkling properties without sacrificing the excellent properties of silk fibers, it is possible to suppress the amount of polymer polymerized to silk as low as possible, and to achieve a sufficient modification effect even with a low polymerization deposition rate. Minimum care as shown is desirable.

(Means for Solving the Problems) The present invention solves the above-mentioned problems and provides a processing method that can improve the moisture wrinkle properties without impairing the excellent properties inherent in silk. The invention is directed to a copolyethylene glycol, which is characterized in that polyethylene glycol dimethacrylate represented by the chemical formula (where n is 8 to 10) is subjected to liquid phase polymerization on silk thread or silk cloth. The reason for limiting the number of polyethylene glyfur residues n f in dimethacrylate to 8 to 10 is because when n is 7 or less, it becomes insoluble in water and generates a large amount of homopolymer, making practical polymerization impossible. , and n is 11 or more (if this happens, the affinity with water will increase, which will not only make it difficult to polymerize and adhere to silk, but also result in poor durability).
This is because it causes problems such as easy flammability.

Liquid phase polymerization is generally carried out in the presence of a radical polymerization catalyst by immersing the processed silk thread or silk cloth in an aqueous solution containing 10 to 20% by weight of polyethylene glycol dimethacrylate based on the weight of silk. As a catalyst, potassium persulfate,
Ammonium persulfate, sodium persulfate, etc. can be used, and are usually added in an amount of 1 to 3% by weight based on the processing agent.

Since the polyethylene glycol dimethacrylate is water-soluble, it is not particularly necessary to add an emulsifier, but an active agent may be added to facilitate the penetration of the processing agent into the fibers.

Through the processing method of the present invention, silk has a unique texture, texture, softness,
Polyethylene glyfur dimethacrylate is a polyethylene glyfur dimethacrylate that can improve the wrinkle resistance when wet, which is a drawback of silk fibers, without sacrificing its characteristics such as hygroscopicity and dyeability. This is thought to be due to the formation of intermolecular crosslinks between silk molecules due to the reaction sites, and in part to the formation of a dense thin film on the fiber surface layer.

68 As shown in Table 68, while there is almost no decrease in moisture content or flexibility, the wet wrinkle resistance is superior to that of unprocessed silk, and even with a relatively low polymerization rate of around 10%, the wet wrinkle resistance is still low. It can be seen that there is a reforming effect.
