MOISTURE-ABSORBING OR RELEASING POLYESTER CONJUGATE FIBER

摘要

PROBLEM TO BE SOLVED: To produce a moisture-absorbing or releasing polyester conjugate fiber having an excellent moisture-absorbing or releasing performance and an improved whiteness, and to produce a moisture-absorbing or releasing polyester conjugate fiber not only having the above properties but also does not cause the splitting of its sheath even after an alkali aqueous solution treatment. ;SOLUTION: A moisture-absorbing or releasing polyester conjugate fiber whose core component is formed from a mixture of a polyalkyleneoxide modified product with a polyester polymerized in the absence of antimony oxide catalyst and whose sheath component is formed from a polyester, characterized in that Taube whiteness is ≥80.;COPYRIGHT: (C)2001,JPO
