polymer fibers containing units of vinyl alcohol having high moisture absorption and high water absorption and process for producing same.

摘要

Fibers composed of polymer containing vinyl alcohol unit, OR PRODUCTS FIBER, YARN OR FIBER COMPOSITE FORMED BY THE PHASE polymer containing vinyl alcohol unit and the other phase polymeric fiber formation ARE Acetalised WITH AT LEAST ONE OF THE COMPOUNDS ALDEHYDES represented by formulas, OHC OHC RUPO alkyl, R1, R2, R3 and R4, independently of one another denote a hydrogen atom or an alkyl group, and at least one of R1 and R2 and at least one of R3 and R4 are alkyl groups and a carboxyl group BECOMES THEN BE IN A SALT FOR FIBER, FIBER YARN OR PRODUCTS WITH HIGH HUMIDITY AND HIGH ABSORPTION water absorption. IN ACCORDANCE WITH invention SHOWN FIBERS, YARN AND FIBER PRODUCTS HAVING resistance, high moisture absorption and high water absorption NOT LOSE EVEN DURING TREATMENT OF DYED OR CLEANING, WHICH ARE SMOOTH AND STRONG AND POSSESS TACT natural fibers; They MAY ALSO made without CAUSARPROBLEMAS IN PHASE fiberizing or coloration.
