Abstract

This invention relates to the high speed drawing method of hank state acryl or nylon spinning yarn. The hank state spinning yarn is wound on a pair of rollers which are laid in a resisting pressure tank, and heated by steam until the internal temperature reaches 100--180≰C. At this temperature the space between two rollers is widened and the spinning yarn kis drawn. At this time the rotation of roller must be kept. After this process, steam is exhausted and the spinning yarn is relaxed and taken out by narrowing the space between two rollers.

Description

방적사의 금속연신방법Metal drawing method of yarn

본 발명은 행크상태의 아크릴, 삭제 및 나일론계의 방적사를 급속연신하여 방적사의 변수를 세번화하는 방법에 관한 것이다.The present invention relates to a method of rapidly stretching the yarns of acrylic yarns, acrylic yarns and nylon-based yarns in the hank state.

본 발명은 방적사를 120수 이상의 극세사로 연신하여 복합데니아의 형성, 그리고 고분자의 물성변화로 흡습성이 우수하고 정전기 및 보푸라기의 형성을 방지하며, 광택과 촉감이 천연실크에 비견되도록 하는데 그 목적이 있다.The present invention is to stretch the spun yarn to more than 120 microfiber yarns to form a composite denia, and to change the physical properties of the polymer is excellent hygroscopicity, to prevent the formation of static and lint, and to have a gloss and feel compared to natural silk .

본 발명자의 특허 제16423호인 “아크릴 방적사의 번수를 세번화시키는 방법”에 의하면, 100수 이상의 세번화가 가능하나 연화상태에 이르는 높은 온도를 유지하는데 소요되는 비용이 과다하고 고압증기의 위험부담이 따르는 문제점이 대두되고 있다.According to the inventor's patent No.16423, "Method of Triplening the Number of Acrylic Spinning Yarns," it is possible to triple the number of 100 or more, but the cost of maintaining the high temperature reaching the softened state is excessive and the risk of high pressure steam is accompanied. This is emerging.

본 발명은 위 특허발명의 결점을 보완하고 급속연신에 의하여 작업시간을 단축시켜 생산성을 크게 향상시킨 것으로서, 본 발명의 방법을 상술하면 다음과 같다.The present invention is to compensate for the shortcomings of the above patent invention and to significantly improve the productivity by shortening the working time by rapid stretching, the method of the present invention will be described in detail as follows.

내압용 탱크내에 수평으로 가설된 한쌍의 로울러에 행크상태의 방적사를 걸고 밀폐시킨 후 증기로 증열시켜 최적연신온도에 이르게 한다.Hank's spinning yarn is fastened to a pair of rollers installed horizontally in a pressure resistant tank, and then steamed and steamed to reach an optimum drawing temperature.

이 경우 최적연신온도는 방적사의 형태 및 원면의 제조공법에 따라 차이가 있으나 통상의 100℃ 내지 180℃의 범위에 이른다.In this case, the optimum stretching temperature varies depending on the type of yarn and the fabrication method of the cotton, but reaches a range of 100 to 180 ° C.

탱크내부의 온도가 최적연신온도에 이르면 행크상태의 방적사가 장진된 한쌍의 로울러를 급속히 벌려 방적사를 연신시킨다.When the temperature inside the tank reaches the optimal stretching temperature, the yarn is stretched by rapidly opening a pair of rollers loaded with hanks of yarn.

이때, 장진된 방적사가 균일하게 연신되도록 로울러를 계속회전시키는 것이 긴요하다.At this time, it is important to continuously rotate the rollers so that the loaded yarn is evenly drawn.

방적사가 소정의 길이로 연신되면 탱크내부의 증기를 배출시킴과 동시에 로울러의 간격을 수축함으로써 방적사를 릴렉싱시켜 인출하게 된다.When the yarn is stretched to a predetermined length, the inside of the tank is discharged, and at the same time, the spacing of the rollers is shrunk to relax and pull out the yarn.

실시예 1Example 1

인장강도 300g, 행크장 80cm, 전장 160cm의 아크릴방적사 52/2수를 내압탱크 내에서 한쌍의 로울러에 수평으로 걸어 장진한 후 증기를 충전하여 최적연신온도에 이르게 하였다.An acrylic spun yarn 52/2 of 300g tensile strength, 80cm long and 160cm long was stretched horizontally to a pair of rollers in a pressure-resistant tank and filled with steam to reach an optimum stretching temperature.

최적연신온도에 이른후 로울러를 급격히 벌려 1차인장충격을 가한 후 30초 이내에 2배 이상 연신시킨 후 증기를 배출시키면서 방적사를 소정의 길이로 릴렉싱하여 수축되도록 하였던바, 아크릴방적사는 100/2수로 극세화되었고 인장강도 600 신도 12%라는 품질의 향상을 확인할 수 있었으며, 천연실크와 같은 광택과 촉감을 구유하게 됨을 알게 되었다.After reaching the optimum stretching temperature, the roller was sharply opened to apply the first tensile shock, and then stretched more than twice within 30 seconds, and then the steam was discharged to relax and shrink to a predetermined length. It was found to be ultra fine and improved in quality with a tensile strength of 600% for elongation of 12%, and it was found to possess the same gloss and feel as natural silk.

본 발명의 방법에 의하여 연신된 방적사는 현재의 기술 수준으로서는 이미 연신의 한계점에 이른 토우 및 방적사를 다시 연신시켜 극세사를 제조하는 목적을 달성하고 있을뿐만 아니라, 연신된 방적사의 강도와 신도가 비례하여 증가되는 탁월한 효과를 가지며 방적사의 물성변화를 일으켜 천연실크와 같은 정도의 광택과 촉감을 얻을 수 있는 것이다.The yarn stretched by the method of the present invention not only achieves the purpose of manufacturing microfiber by stretching the tow and yarn that has already reached the limit of stretching as the current technology level, but also in proportion to the strength and elongation of the stretched yarn. It has an excellent effect of increasing and causes a change in the properties of the yarn to obtain the same gloss and feel as natural silk.
