Abstract
본 발명은 방사속도 5.500m/분 이상의 초고속방사공법에 의해서 폴리에스터 섬유를 제조함에 있어서, 방사구금에서 압축된 사조를 실린더(직선형)형태의 아래의 식을 만족하는 비접촉식 히터로 가열함에 의해 일반 연신사 수준의 비수수축률 (7~8%)을 갖게 하는 것을 특징으로 하는 폴리에스터 섬유의 제조방법을 제공하는 것으로, 본 발명에 방법에 의해 제조되는 폴리에스터 섬유는 초고속방사공법에 의해 제조하여도 일반 연신사수준의 비수수축률을 갖기 때문에 제직 후 직물밀도가 저하되지 않아 고품위의 직물로 제조될 수 있는 이점을 갖는다. 히터 반경(㎜)=A×단사직경 상기 식에서, A는 실험상수로서, 제1히터; A = 15~20의 범위를 갖는 실험상수, 제2히터; A=40~50의 범위를 갖는 실험상수, 단사직경(0.54㎜)=75d/36f(15μ)×필라멘트수(36).The present invention is to produce a polyester fiber by the ultra-fast spinning method with a spinning speed of 5.500m / min or more, by heating the thread yarn compressed in the spinneret by a non-contact heater that satisfies the following equation of the cylinder (linear) form To provide a method for producing a polyester fiber characterized in that it has a non-shrinkage rate (7 ~ 8%) of the gentleman level, the polyester fiber produced by the method according to the present invention is general even if manufactured by the ultra-fast spinning method Since it has a non-shrinkage rate of the stretched yarn level, the fabric density does not decrease after weaving, so it can be manufactured into a high quality fabric. Heater radius (mm) = A x single-diameter In the above formula, A is the experimental constant, the first heater; A = Experimental constant, the second heater having a range of 15-20; Experimental constant having a range of A = 40-50, single yarn diameter (0.54mm) = 75d / 36f (15μ) x number of filaments (36).
