Abstract
A modified regenerated cellulose fiber which enables dyeing in different colors by combining the modified regenerated cellulose fiber and other fibers by means of mixed spinning or union knitting/weaving. The modified regenerated cellulose fiber can be obtained by adding 0.5–3.0% by weight of a grounder of naphthol dye to the regenerated cellulose fiber in a matrix of the regenerated cellulose fiber, the grounder being selected from the group having a medium to high level of affinity to the regenerated cellulose fiber. A variety of dyed fiber products can be obtained by treating yarn or knitted/woven fabric made of the above modified regenerated cellulose fiber with a developer of naphthol dye.
