CHITOSAN-CONTAINING ACRYLIC FIBERS AND PROCESS FOR PREPARING THE SAME

摘要

Chitosan-containing acrylic fibers having a total chitosan content of 0.05 to 2 % by weight and an extractable chitosan content of not less than 0.03 % by weight to less than the total chitosan content. The antimicrobial activity of the fibers can persist for a long period of time and is not deteriorated even when subjected to posttreatments, such as dyeing and bleaching of fibers, and treatments in usual service environments of fiber products, such as washing and ironing.
