Abstract

본 발명은 태섬도사를 코아부에, 세섬도사는 이펙트부에 존재하는 폴리에스테르계 이섬도혼섬사의 제조방법임.The present invention is a method for producing a polyester-based isomdo blended yarn present in the core part, sesame dosa in the effect portion.

본 발명은 구금중심선으로부터 대칭의 2개군의 토출공을 동시에 방사, 냉각, 고화시킨다음 2단의 제1권취롤러에 통과시키되, 태섬도의 제1필라멘트군은 선속도가 낮은 곳에 권회하여 유리전이온도보다 5℃이상인 온도에서 최대연신배율의 85%이상으로 완전연신을 하고, 세섬도의 제2필라멘트군은 선속도 높은 곳에 권회하여 유리전이온도이하의 온도에서 최대연신배율의 75~85%의 연신배율로 불완전연신을 한 다음 권취직전에 교락처리함을 특징으로 하는 폴리에스테르계 이섬도혼섬사의 제조방법임.The present invention simultaneously radiates, cools and solidifies the discharge holes of two groups symmetrically from the center of detention line and passes them through the first winding roller of two stages. At the temperature above 5 ℃, it is completely stretched to more than 85% of the maximum draw ratio, and the second filament group of Sesido is wound at a high linear velocity, so that it is 75 ~ 85% of the maximum draw ratio at the temperature below the glass transition temperature. A method for producing polyester-based isomido blended yarns, characterized by incomplete stretching at a draw ratio, followed by entanglement treatment immediately before winding.

폴리에스테르계 이섬도혼섬사를 동시 방사 및 직접연신법으로 제조함에 있어서, 열가소성 폴리에스테르계 수지를 구금중심선으로부터 대칭적으로 천공된 2개군의 토출공을 통해 동시에 방사하고, 이어서 선속도가 2단으로 되어 있는 계단식 제1권취롤러에 태섬도의 제1필라멘트군과 세섬도의제2필라멘트군을 각 권희한 후, 태섬도의 제1필라멘트군을 유리전이온도보다 5℃이상인 온도에서 최대연신배율의 85% 이상의 연신배율로 완전연신을 하고, 세섬도의 제2필라멘트군은 유리전이온도이하의 온도에서 최대연신배율 75~85%의 연신배율로 불완전 연신을 한 후, 권취직전에 교락처리함을 특징으로 하는 폴리에스테르계 이섬도혼섬사의 제조방법.In the simultaneous spinning and direct drawing of polyester-based islet blended yarns, thermoplastic polyester-based resins are simultaneously spun through two groups of discharge holes symmetrically punched from the center of detention, and then linear speed is After winding each of the first filament group and the second filament group of the sesame island on the stepped first winding roller, the maximum draw ratio at the temperature of 5 ° C or higher than the glass transition temperature. Fully stretched at 85% or more of draw ratio, and the second filament group of Sesudo Island is incompletely drawn at the draw ratio of 75 ~ 85% of maximum draw ratio at the temperature below the glass transition temperature, and then entangled immediately before winding. Method for producing a polyester-based isom island blend yarn. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
