Claims (2)

저수축성분으로서 고유점도가 0.65-0.70인 폴리에스테르 수지를 사용하고, 고수축성분으로서 고유점도가 저수축성분보다 0.1이상 차이가 나는 고유점도가 0.75-0.80인 공중합 폴리에스테르 수지를 사용하여 저수축부-고수축부-저수축부의 단면형태(제3도의 단면형태)를 갖는 복합사를 방사하되, 저수축부 : 고수축부 : 저수축부의 중량비가 1:2:1이 되도록 방사한 다음, 1단 연신 배율이 총연신배율의 60-80%가 되게 1단 연신하고 이어서 2단 연신하는 잠재권축성 복합사의 제조방법.Low shrinkage is achieved by using a polyester resin with an intrinsic viscosity of 0.65-0.70 as a low shrinkage component, and a copolyester polyester resin with an intrinsic viscosity of 0.75-0.80 having an intrinsic viscosity of at least 0.1 difference from the low shrinkage component as a high shrinkage component. Spinning the composite yarn having the cross-sectional shape of the sub-high shrinkage portion-low shrinkage portion (the cross-sectional shape of FIG. 3), and the low shrinkage portion: high shrinkage portion: spun so that the weight ratio of the low shrinkage portion is 1: 2: 1, and then A method for producing a latent crimped composite yarn in which the draw ratio is drawn in one step so that the draw ratio is 60-80% of the total draw magnification and then drawn in two steps. 제1항에 있어서, 2단 연신함에 있어서, 예열로울러의 온도를 85℃정도로 하고, 제2로울러의 온도를 110℃-130℃로 하는 잠재권축성 복합사의 제조방법.The method for producing a latent crimped composite yarn according to claim 1, wherein in the two-stage drawing, the preheating roller temperature is about 85 ° C and the second roller temperature is 110 ° C-130 ° C. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
