Abstract

본 발명은 이수축혼섬사의 제조방법에 관한 것이다.The present invention relates to a method for producing biaxial mixed fiber.

종래의 제조방법으로 제조나 이수축혼섬사는 가공사의 상태에서 모우나 루우프를 발생시켰으며 고, 저수축사간의 분리현상 때문에 경사줄을 일으키는 문제점이 있었다.In the conventional manufacturing method, the production or di-shrink blended yarn produced the mouna or loop in the state of the processed yarn, and there was a problem of causing the slanted line due to the separation phenomenon between the low shrinkage yarn.

본 발명은 혼섬성이 좋으며 루우프나 모우를 발생시키지 않은 이수축혼섬사의 제조방법으로서 고배향 고수축 미연신사 2본을 사용하여 그 1본을 그대로 가열연신역에 공급하고 타 1본은 열처리해서 고배향 저수축 미연신사로 만든 다음에 가열연신역에 공급하여서 양자를 1.2배 열연신 한 다음 공기교락시켜서 제조하는 방법임.The present invention is a method of producing bishrink blended yarn which has good blending properties and does not generate loops or mousse. It is made by oriented low-shrink unstretched yarn, and then supplied to heated stretched zone and heat-stretched 1.2 times and then air entangled.
