Title:
POLYESTER CONJUGATE FIBER
Document Type and Number:
Japanese Patent JP3473890
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To obtain a polyester conjugate fiber capable of giving a cloth which can express adequate degree of crimp shrinkage by a heat treatment, and has soft and bulky feeling while keeping smooth surface property, and useful for the usage of an outer wear an inner, a sportswear or the like free from stretching feeling on elbows and knees when they are bent and having good wearability.
SOLUTION: In side-by-side polyester conjugate fiber consisting of a first component and a second component, the first component is a polytrimethylene terephthalate polymer having the intrinsic viscosity [η] of 0.4-1.0, and the second component is a polyester polymer whose melt viscosity is higher than that of the first component by 200-500 poise. The both components are closely adhered to each other over the whole length of the fiber, and are arranged in a parallel or eccentric state.
