THERMOPLASTIC CELLULOSE ESTER COMPOSITION AND FIBERS MADE THEREFROM

摘要

Disclosed is fibers made from thermoplastic cellulose ester composition, and the thermoplastic cellulose ester composition that configures the fibers, which can maintain excellent mechanical properties even after high-temperature dyeing, and especially, which are well suited to commingling, inter-knitting, and interweaving with polyester fibers. The thermoplastic cellulose ester composition and fiber made therefrom are characterized by containing at least 70-95% by weight cellulose-fatty acid mixed ester with an average degree substitution of 2.4-2.8, 5-25% by weight plasticizer, and 1-10% by weight cellulose acetate with an average degree substitution of 2.3-2.6.
