Abstract

PURPOSE: Elastic yarns, consisting of a block copolymer containing polyethylene terephthalate polyester as hard segments and polyoxybutylene glycol polyether as soft segments, and easily obtained by the melt spinning method.
CONSTITUTION: Terephthalic acid (dimethyl terephthalate) is reacted with butylene glycol and polyoxybutylene glycol having an average molecular weight of 500W5,000, preferably 800W3,000, under heating to give a block polyether polyester copolymer, containing polybutylene terephthalate polyester as hard segments and polyoxybutylene glycol polyether as soft segments at a weight ratio between the soft and the hard segments of preferably 0.4W2.5. The resultant polyether polyester is then melt spun to afford elastic yarns.
EFFECT: Mutual sticking of filaments by fusion scarcely occurs in the melt spinning.
