Embodiment 1

[0088] First, 0.25 g of RDGE (DENACOL EX201; manufactured by Nagase ChemteX Corporation) and 0.5 g of a dispersant (Disper VG; manufactured by Meisei Chemical Co., Ltd.) were sufficiently kneaded, and the kneaded product was placed in a stirring tank. Then, water was slowly added to the kneaded product to emulsify and disperse it, thereby preparing a treatment liquid containing RDGE. It should be noted that the total amount of water used was 200 ml. Next, 5 g of silk crepe (manufactured by Nagahama Chirimen Co., Ltd.) was immersed in the prepared treatment liquid. It should be noted that the weight per unit area of ​​silk crepe is 150g / m 2 . The treatment liquid in which the silk crepe was immersed was stirred in order to uniformly bond the epoxy compound to the silk crepe.

[0089] Then, the temperature of the treatment liquid was raised from 25° C. to 60° C. while slowly adding a diluted sodium hydroxide aqueous solution obtained by diluting 1.25 g of a 24% sodium hydroxi...

Embodiment 2

[0092] First, a solution of 0.25 g of HDGE (DENACOL EX203; manufactured by Nagase ChemteX Corporation) dissolved in 0.7 g of DMF was sufficiently kneaded with 1.7 g of a dispersant (Disper VG; manufactured by Meisei Chemical Co., Ltd.). contained in a stirred tank. And, the treatment liquid was prepared by the same method as in Example 1. Except for the above, by the same method as Example 1, the processed silk crepe was produced. It should be noted that 2 processed silk crepes are made.

Embodiment 3

[0112] Except using 5 g of silk spinning silk 6 Japan Ryo (manufactured by Konno Kigyojo Corporation (Fukushima Prefecture)) instead of 5 g of silk crepe (manufactured by Nagahama Chirimen Co., Ltd.), utilize the same method as in Example 1 to produce Processed silk spinning silk 6 Japanese taels. It should be noted that the weight per unit area of ​​silk spinning silk 6 Japanese taels is 20g / m 2 .

Abstract

The modified fiber according to the present invention pertains to a modified fiber having high abrasion resistance in wet conditions and having high washing resistance. A modified fiber in which an epoxy compound has been bonded to a refined cellulose fiber, a natural cellulose fiber, a cuprammonium rayon, rayon, or silk fiber, the modified fiber being characterized in that the epoxy compound is resorcinol diglycidyl ether and/or hydroquinone diglycidyl ether.

Description

technical field [0001] The present invention relates to modified fiber and its manufacturing method. More specifically, it relates to a modified fiber in which an epoxy compound is bonded to purified cellulose fiber, natural cellulose fiber, cuprammonium rayon, rayon, or silk fiber, and a method for producing the same. Background technique [0002] Silk fiber is widely known for its unique luster and good touch, and it is widely used as a high-grade fiber. Refined cellulose fiber and cuprammonium rayon are regenerated cellulose fibers made of silk fiber as a mold, and have a luster and touch close to silk fiber. Examples of such regenerated cellulose fibers include purified cellulose fibers "TENCEL (registered trademark)" and "Lyocell (registered trademark)" sold by Lenzing, and cuprammonium rayon "Bemberg (registered trademark)" sold by Asahi Kasei Fiber Co., Ltd. Trademark)” etc. [0003] It is known that silk and regenerated cellulose fibers have high utility value for...
