Zusammenfassung:	PURPOSE: A manufacturing method of polyester false twist yarn is characterized by cool-drawing and false-twisting polyester undrawn yarn at low speed. The polyester false twist yarn maintains excellent elongation elasticity and has excellent crimp fastness and elasticity. CONSTITUTION: Polyester false twist yarn is obtained by drawing polyester undrawn yarn at 20-50deg.C at 150-200m/min of drawing velocity with a draw winder. The polyester false twist yarn is manufactured by using polyethylene terephthalate or polytrimethylene terephthalate. The elongation elasticity is 40%. 본 발명은 폴리에스테르 미연신사를 이용한 폴리에스테르 가연사를 제조하는 방법에 관한 것으로, 본 가연사는 폴리에스테르 미연신사를 상온에서 저속으로 냉연신을 하여 폴리에스테르 가연사를 제조하는 방법으로서, 꼬임이 균일하고 크림프 견뢰도 및 신축성이 우수한 폴리에스테르 가연사를 제조할 수 있는 장점이 있다.
