Abstract

PURPOSE: A block copolymer of polybutylene terephthalamide and polyalkylene ether glycol is melt-spun, drawn and heat treated under relax to produce elastic fiber of high heat stability, light resistance, chemical resistance and elastic properties.
CONSTITUTION: The esterification reaction between terephthalic acid, 1,4-butanedial, and polytetramethylene ether glycol is effected in the presence of a catalyst such as titanium tetrabutoxide and followed by polycondensation reaction to produce a block copolymer containing polybutylene terephthalate copolyester as the hard segment and polytetramethylene ether glycol as the soft segment. The block copolymer is melt-spun, drawn at more than 2 draw ratio and heat treated at a temperature higher than 70°C under relex to produce the objective elastic fiber.
