Abstract

본 발명은 단사섬도가 0.8 데니어 이하의 것으로 되어 있는 폴리아미드 극세사의 제조방법이다.The present invention is a method for producing polyamide microfiber yarn having a single yarn fineness of 0.8 denier or less.

본 발명은 단사섬도가 1.4~2.5 데니어가 되도록 방사한 것을 1차로 1.1~1.8배 연신 후 10 TPM 이상으로 꼬임을 주면서 권취하고, 상기 사를 2차로 2.75~2.9배로 연신하여서 단사섬도가 0.8데니어 이하인 극세사의 제조방법으로서 종래처럼 랩(wrap)을 발생시킴이 없이 조업성이 좋게 제조할 수 있도록 하는 것임.In the present invention, the single yarn fineness radiated so as to be 1.4 to 2.5 deniers firstly stretched 1.1 to 1.8 times and then twisted with 10 TPM or more, and the yarns were stretched to 2.75 to 2.9 times and the single yarn fineness was 0.8 denier or less. As a manufacturing method of microfiber, it is possible to manufacture with good operability without generating a wrap as in the prior art.
