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.
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.
