Title:
ABRASION-RESISTANT POLYESTER FIBER AND WOVEN/KNITTED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2012/014309
Kind Code:
A1
Abstract:
Provided is an abrasion-resistant polyester fiber, which has, in particular, a strength within a specific range, an elongation within a specific range and a Young's modulus falling within a specific range in a specific elongation range on a stress-strain curve, to improve the abrasion resistance of a woven/knitted product for clothing using, in particular, a fine size polyester fiber. The polyester fiber is an abrasion-resistant polyester fiber comprising ethylene terephthalate as a main repeating unit, characterized by satisfying the following requirements:
(1) the fineness being from 8 dtex to 200 dtex inclusive;
(2) the single yarn fineness being from 1.0 dtex to 4.0 dtex inclusive;
(3) the breaking strength being 3.5 cN/dtex or greater;
(4) the breaking elongation being from 20% to 50% inclusive; and
(5) the minimum differential Young's modulus being 20 cN/dtex or less in an elongation range of from 2% to 5% inclusive on a stress-strain curve of the fiber.
