Modifizierte regenerierte Cellulosefaser

摘要

The present invention simplifies the complicated dyeing process using a naphthol dye, and provides 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. A modified regenerated cellulose fiber can be obtained by having 0.5 to 3.0% by weight of naphthol dye grounder to the regenerated cellulose fiber in a matrix consisting of the regenerated cellulose fiber, wherein the grounder has 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 regenerated cellulose fiber with a naphthol dye developer.
