MODIFIED REGENERATED CELLULOSE FIBER AND TEXTILE PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a modified regenerated cellulose fiber effective for simplifying the complicate process for the dyeing with a naphthol dye and enabling varicolored dyeing by combining the modified regenerated cellulose fiber with other fiber by blending or combined knitting or weaving. SOLUTION: The modified regenerated cellulose fiber is produced by using a grounding agent for naphthol dye selected from a group having medium to high affinity to regenerated cellulose fiber and incorporating the grounding agent into the matrix of regenerated cellulose fiber in an amount of 0.5-3.0 wt.% based on the regenerated cellulose fiber. Various textile products can be produced by the color-development of the yarn or the woven or knit fabric of the modified regenerated cellulose fiber by the treatment with a color- developing agent for naphthol dye.
