METHOD OF PRODUCING HEAT-RESISTING CRIMPED YARN

摘要

A method of producing a crimped yarn, comprising twisting heat-resisting, hi gh- function fiber filaments followed by twist-setting by heat treating, and the n untwisting the twisting, wherein a method of producing a heat-resisting crimped yarn is characterized in that the snarl value of filaments after twi st- setting is up to 6.5, whereby providing a method of producing a heat-resisti ng crimped yarn, which is practical in terms of productivity, equipment or cost .
