POLYESTER-BASED COMBINED FILAMENT UNDRAWN YARN HAVING EXCELLENT COLOR-DEVELOPING PROPERTY AND EXCELLENT ANTISTATIC PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a polyester-based combined filament undrawn yarn having an excellent color-developing property and an excellent antistatic property.;SOLUTION: This polyester-based combined filament undrawn yarn comprising two kinds of fiber groups A, B having different elongations is characterized by the following characteristics. The high elongation fiber group A contains colloidal fine particles having an average primary particle diameter of 0.02 to 0.1 μm in an amount of 0.4 to 5 wt. %. The low elongation fiber group B has an elongation of ≥80 %, and contains 0.2 to 10 wt. % of a highly hydrophilic polymer as an antistatic agent. An elongation difference between the fiber group A and the fiber group B is ≥20 %.;COPYRIGHT: (C)2006,JPO&NCIPI
