MODIFIED POLYESTER FIBER, OPAL FINISHED WOVEN AND KNITTED FABRIC CONTAINING THE FIBER, AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2017/010024

Kind Code:

A1

Abstract:

Provided is a modified polyester fiber which is used as a fiber having reduced weight, the modified polyester fiber comprising ethylene terephthalate as a primary constituent unit and being obtained by copolymerizing 12-25 mol.% of an aliphatic dicarboxylic acid having 4-8 carbon atoms and 2-5 mol.% of a metal sulfonate group-containing aromatic dicarboxylic acid. This modified polyester fiber has a single fiber fineness of 0.6-3.5 dtex. In a mixed woven and knitted fabric comprising two or more types of fiber consisting of the modified polyester fiber and a regular polyester fiber and, optionally, a polyurethane fiber, good opal finish properties can be achieved by an opal finish agent that contains sodium carbonate and, for example, a Mei printer OP-2 (manufactured by Meisei Chemical Works, Ltd.), which is an opal finish accelerator, and a reduction in strength of non-opal finished parts is also low.
