Claims (1)

고유점도가 0.65인 폴리에틸렌테레프탈레이트와 고유점도가 0.73인 고수축성이며 동종의 폴리에스테르 공중합물을 섬유단면에서 고수축성성분의 함량비율이 50%-80%가 되도록 접합형(Side by Side)형태로 복합방사한 다음, 80℃-100℃에서 3.8-3.9배로 연신하고, 이어서 175℃-220℃에서 20%-28%정도로 이완열처리를 하고, 다시 65℃이하에서 5%-9%로 긴장열처리를 하는 잠재권축성 폴리에스테르 복합섬유의 제조방법.Polyethylene terephthalate with an intrinsic viscosity of 0.65 and a highly shrinkable, homogeneous polyester copolymer with an intrinsic viscosity of 0.73 are in the form of Side by Side so that the content ratio of the highly shrinkable component in the fiber section is 50% -80%. After complex spinning, the film was stretched to 3.8-3.9 times at 80 ° C.-100 ° C., and then relaxed heat treated at 20% -28% at 175 ° C.-220 ° C., and further subjected to tension heat treatment at 5% -9% below 65 ° C.
