Abstract

본 발명은 폴리에스터 필라멘트의 제조방법에 관한 것으로, 좀 더 구체적으로는 기존의 연신장치를 다소 개조하여 사 제조시 2종의 폴리에스터 부분 미연신사의 사도를 달리하여 연신 및 열처리를 거쳐 합사한 후 이완열처리를 행하여 제조하는 방법으로 원사상태에서는 벌키성이 전혀 없으나, 제직 및 편직후 열처리, 염색 등의 공정을 거치면서 천연섬유와 같은 촉감 및 색상을 나타내는 특징이 있다.The present invention relates to a method for producing a polyester filament, and more specifically, after fabricating by slightly modifying the existing stretching apparatus, the yarns of two kinds of polyester partially undrawn yarns are stretched and heat-treated and then plyed together. It is a method of manufacturing by loosening heat treatment, but there is no bulkiness in the yarn state, but after weaving and knitting, heat treatment, dyeing, etc., it has the characteristic of showing the same feel and color as natural fibers.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (4)

2종의 폴리에스터 부분 미연신사를 혼섬함에 있어서, 동일 연신장치에서 1종의 폴리에스터 부분 미연신사(1)은 연신 및 열처리를 동시에 행하고 또 다른 폴리에스터 부분 미연신산(2)는 연신과 열처리를 분할하여 행한 후 각각의 연신사를 합사하고 이완처리함을 특징으로 하는 폴리에스터 필라멘트의 제조방법.In blending two kinds of polyester partially undrawn yarns, one polyester partially undrawn yarn (1) is drawn and heat treated at the same time in the same drawing apparatus, while another polyester partially unstretched acid (2) is drawn and heat treated. A method for producing a polyester filament, characterized in that after the division is carried out, each of the drawn yarns are spliced and relaxed. 제1항에 있어서, 폴리에스터 부분 미연신사(1)와 폴리에스터 부분미연신사(2)의 파단신도차는 아래식을 만족함을 특징으로 하는 폴리에스터 필라멘트의 제조방법.The method of manufacturing a polyester filament according to claim 1, wherein the elongation at break between the polyester partially undrawn yarn (1) and the polyester partially undrawn yarn (2) satisfies the following formula. A-B=30~80(%)A-B = 30 ~ 80 (%) 여기에서, A는 폴리에스터 부분미연신사(1)의 파단신도(%), B는 폴리에스터 부분미연신사(2)의 파단신도(%).Here, A is the elongation at break (%) of the polyester partially undrawn yarn (1), B is the elongation at break (%) of the polyester partially undrawn yarn (2). 제1항에 있어서, 폴리에스터 부분 미연신사(1)의 연신배율(D. R)은 하기 식을 만족함을 특징으로 하는 폴리에스터 필라멘트의 제조방법.The method for producing a polyester filament according to claim 1, wherein the draw ratio (D.R) of the polyester partial unstretched yarn (1) satisfies the following formula. D. R=(파단신도/100)×0.95~1.15D. R = (Elongation at Break / 100) × 0.95 to 1.15 제1항에 있어서, 이완열처리시에 이완율은 5% 이하임을 특징으로 하는 폴리에스터 필라멘트의 제조방법.The method for producing a polyester filament according to claim 1, wherein the relaxation rate is about 5% or less during the relaxation heat treatment. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
