METHOD FOR PRODUCING POLYURETHANE UREA FIBER INCLUDING COMBINATION OF POLYDIMETHYLSILOXANE, ALKOXYLATED POLYDIMETHYLSILOXANE, AND FATTY ACID SALT IN SPINNING SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane urea fiber in high productivity with bringing data of textile yarns to be constant over the whole spinning process. SOLUTION: The polyurethane urea fiber is produced by bringing a spinning solution to contain a combination of polydimethylsiloxane, an alkoxylated polydimethylsiloxane and a fatty acid salt, and dry spinning or wet spinning the spinning solution with including spinning, finishing and twisting. The polyurethane urea fiber and the method for producing the same are claimed. COPYRIGHT: (C)2004,JPO&NCIPI
