Abstract

A copolyester resin for preparing a low-melting copolyester fiber is made by compounding a first copolyester with a second copolyester in a weight ratio of the first copolyester to the second copolyester of from 94:6 to 98:2. The first copolyester is obtained by subjecting terephthalic acid, ethylene glycol, isophthalic acid, and diethylene glycol to a copolymerization, and the second copolyester is obtained by subjecting terephthalic acid, ethylene glycol, and neopentyl glycol to another copolymerization.
