Document Type and Number:
WIPO Patent Application WO/2013/137263
Kind Code:
A1
Abstract:
Provided is a superfine polyester fiber containing at least 98 wt% of a polyethylene terephthalate component, and characterized by fulfilling the following conditions: (1) the reduced viscosity (ηsp/c) is at least 0.80 dl/g; (2) the total fineness is 7-120 dtex, and the single fiber fineness is no more than 0.5 dtex; the toughness parameter (X) indicated by formula (1) is at least 2.0, the tensile strength is at least 3.5 cN/dtex, and the tensile elongation is at least 12%. X = (tensile strength ×√tensile elongation)/(total fineness × single fiber fineness) … formula (1).
