Abstract
Description
제1도는 본 발명의 공정개략도.1 is a process schematic diagram of the present invention.
제2도는 종래것의 공정개략도.2 is a process schematic diagram of the conventional one.
본 발명은 주로 심레즈 스타킹(Seamless Stocking)용으로 사용되는 세섬도의 폴리아미드 모노 포이-가연사(Poy-)의 제조방법에 관한 것이다.The present invention is a fine-grained polyamide mono poi-twisted yarn (Poy-) mainly used for seamless stocking. It relates to a method of manufacturing).
종래의 소위 DUY-DTY 제조법은 저속방사(1500m/분 이하)법으로 제조한 폴리아미드 모노 미연신사를 만든다음 이것을 가연(假撚)공정에서 2단에 걸쳐서 연신하고 그 연신배율도 4배 정도로 크게하는 이웁드로우방식(Out Draw Process)으로 제조하는 것이었다.Conventional so-called DUY-DTY manufacturing method is made of polyamide mono-stretched yarn produced by the low-speed spinning (1500m / min or less) method and stretched in two stages in the combusting process and the draw ratio is about 4 times larger It was manufactured by the Out Draw Process.
따라서 종래의 방법은 생산성이 낮음은 물론이거니와 가연공정에서 미연신사를 사용하므로서 사질()의 불안정과 폐사를 많이 발생시켰으며 에너지의 소모도 많았던 결점이 있었다.Therefore, the conventional method is not only low productivity, but also by using undrawn yarn in the combustion process. ), Which caused many instability and mortality, and consumed a lot of energy.
본 발명은 이와 같은 문제점을 해결한 것으로서 이하 상세히 설명하면 다음과 같다.The present invention solves such a problem as described below in detail.
제1도는 본 발명의 제조공정을 나타낸 개략도이고, 제2도는 종래공정의 개략도이다.1 is a schematic view showing the manufacturing process of the present invention, Figure 2 is a schematic view of a conventional process.
본 발명은 권취사속이 4,000-4,500m/분이 되도록 고속방사를 하고 권취장력도 종래의 0.5g/d에 비하여 높게 1g/d 이상이 되도록 하였다. 아울러 본 발명에서는 냉각부인 켄치스크린의 길이를 종래것(약 100cm)보다 길게 180-200cm가 되도록 하여서 고속방사에 맞추어서 사냉각이 충분하게 이루어지도록 하여 폴리아미드 모노 포이사(Mono Poy)를 제조한다.In the present invention, high-speed spinning was performed so that the winding speed was 4,000-4,500 m / min, and the winding tension was 1 g / d or more higher than that of the conventional 0.5 g / d. In addition, in the present invention, the length of the quench screen, which is a cooling unit, is 180-200 cm longer than the conventional one (about 100 cm), so that four-cooling is sufficiently made in accordance with high-speed spinning to produce polyamide mono poy.
가연공정에 있어서는 인드로우방식(In Draw Process)을 채용하여서 1단연신만을 받도록 하고 동시에 연신비도 종래의 연신배율(3-4배)보다 적은 1.2-1.3배로 연신하여 세섬도(15-20데니어)의 폴리아미드 모노 포이-가연사를 제조한다.In draw process, it adopts In Draw Process to receive only one-stage drawing and at the same time draw ratio is 1.2-1.3 times less than conventional drawing ratio (3-4 times). Polyamide mono poi-twisted yarn is prepared.
본 발명은 Poy사를 사용하여서 인드로우방식에 의거 낮은 연신비로 가연 가공하는 방법이므로 종래에 비하여 2배 정도의 생산성향상을 기할 수 있으며 미연신사를 사용하지 않고 Poy사를 사용하여 가연가공하기 때문에 절사가 감소되고 우수한 사질의 제품을 생산할 수 있다.The present invention is a method of twisting at low draw ratio based on in-draw method using Poy yarn, which can improve productivity by about 2 times compared to the conventional one, and cut by cutting by using Poy yarn without using undrawn yarn. Can be reduced and a good quality product can be produced.
[실시예]EXAMPLE
폴리아미드 모노 필라멘트 15데니어를 본 발명의 제조방법과 종래의 제조방법에 의하여 표 (1)의 조건으로 제조하였다.Polyamide monofilament 15 denier was prepared under the conditions of Table (1) by the production method of the present invention and the conventional production method.
[표(1)]Table (1)
위 2가지 방법으로 각각 제조한 모노 미연신가연사(Mono UDY-DTY)와 모노 포이 가연사(Mono POY-DTY)의 물성을 비교한 결과는 표 (2)와 같았다.The results of comparing the properties of the mono unstretched twisted yarn (Mono UDY-DTY) and the mono-poy twisted yarn (Mono POY-DTY) prepared by the above two methods were shown in Table (2).
[표(2)][Table (2)]
표 (2)로 알 수 있는 바와 같이 본 발명으로 제조한 실이 강신도가 높고 꼬임의 균일성 때문에 고속 편기(850rpm 이상)에 제편가능하고 편지의 표면이 깨끗한 제품을 얻을 수 있다.As can be seen from Table (2), the yarn produced according to the present invention has a high elongation and can be knitted on a high-speed knitting machine (850 rpm or more) because of the uniformity of twist, and a clean surface of the letter can be obtained.
