Description
제1도는 본발명의 태세사를 제조하기 위한 공정모식도.1 is a process schematic diagram for manufacturing a posture of the present invention.
본 발명은 폴리에스테르 태세사를 우수한 물성으로 제조하는 방법에 관한 것으로 특히 종래의 스핀 드로우 얀(Spin drow Yarn ; 이하 SDY라함) 제조공정중에 간단한 조건의 변경으로 태세효과가 우수한 폴리에스테르 태세사를 제조하는 방법을 제공함을 목적으로 한다.The present invention relates to a method for producing a polyester posture yarn with excellent physical properties, and in particular, to prepare a polyester posture yarn having excellent posture effect by a simple change of conditions during the manufacturing process of the conventional spin drow yarn (hereinafter referred to as SDY). The purpose is to provide a way to.
종래의 태세사를 제조하는 방법으로서는 폴리에스테르를 냉사하여 권취한 후 이를 연신시에 요철이 있는 롤러를 사용하여 연신하는 방법 및 사에 불균일을 유발시키는 복잡한 장치를 부착시켜 연신하는 방법등이 알려져 있었다.As a method for manufacturing a conventional posture yarn, there are known a method of cold-rolling polyester and winding it and stretching it using a roller having irregularities when stretching, and a method of attaching and stretching a complicated device causing non-uniformity to yarn. .
그러나 이러한 방법은 그 공정이 복잡하고 또한 매우 복잡한 장치를 사용하는 것이었기 때문에 조업성이 나쁘고 제조비용이 많이 드는 등의 문제점이 있었으며, 아울러 그에 따른 생산성 저하 및 제조원가 상승의 문제가 있었다.However, this method has a problem such as bad operation and high manufacturing cost because the process is complicated and very complicated device, and there is also a problem of decrease in productivity and increase in manufacturing cost.
본 발명은 상기의 문제점을 해결하기 위해 통상의 SDY 제조공정에서 별도의 장치없이 연신조건을 변경함에 따라 우수한 태세효과를 갖는 태세사를 제공하는데 그 목적이 있는 것으로서 이하 예시도면에 의하여 본 발명을 상세히 설명하면 다음과 같다.The present invention has been made in order to solve the above problems in the conventional SDY manufacturing process in order to provide a poshsasa having excellent posture effect by changing the stretching conditions without a separate device in detail the present invention by the following exemplary drawings. The explanation is as follows.
방사속도 1,500∼2,000m/min으로 방사된 폴리에스테르를 냉각, 고화하고 유체를 부여, 집속시킨 후 온도가 40∼60℃인 제1고뎃롤러와 온도가 50∼70℃인 제2고뎃롤러 사이에서 연신배율 1.7∼2.0으로 연신한 후 권취하여 태세사를 제조하는 것이다.After cooling, solidifying, imparting and concentrating the polyester spun at a spinning speed of 1,500 to 2,000 m / min, the first high speed roller having a temperature of 40 to 60 ° C. and the second high speed roller having a temperature of 50 to 70 ° C. After stretching at a draw ratio of 1.7 to 2.0, it is wound up to prepare a poised yarn.
본 발명의 가장 큰 특징은 제1고뎃롤러의 온도를 40∼60℃로 냉연신을 함에 있는 것으로 통상의 SDY제법에서 균제도 향상 및 연신성 향상을 위해 열연신을 행하는 것과 대조적이다.The biggest feature of the present invention lies in cold drawing the temperature of the first gourd roller at 40-60 ° C., as opposed to performing the heat drawing to improve the evenness and stretchability in the conventional SDY method.
제1고뎃롤러의 온도를 40∼60℃로 하여 냉연신을 행하는 이유는 폴리에스테르 냉연신을 하면 네킹(necking) 현상이 일어나는 원리를 이용한 것이다. 네킹이란 연신에 의하여 섬유가 균일하게 가늘어지는 것이 아니고 섬유의 어느부분이 급속히 가늘어지는 현상을 의미하는 것인데 본 발명에서는 폴리에스테르를 냉연신함에 따라 네킹부분을 조절하여 우수한 태세효과를 갖는 태세사를 얻을 수 있다.The reason for cold drawing using the temperature of the first gourd roller at 40 to 60 ° C is based on the principle that the necking phenomenon occurs when cold drawing is performed. The necking means that the fiber is not uniformly tapered by stretching, but a phenomenon in which a portion of the fiber is tapered rapidly. According to the present invention, by adjusting the necking portion according to cold stretching of the polyester, a posture yarn having excellent posture effect can be obtained. Can be.
본 발명에서 방사속도(제1고뎃롤러의 속도)를 1,500∼2,000m/min으로 한정한 이유는 방사속도가 1,500m/min 미만일 경우 방사속도가 너무 낮아 공정이 나빠지는 등의 생산성 저하의 문제가 있으며, 2,000m/min을 초과하는 경우는 연신효과 증대 및 태세효과 감소로 염색성이 나빠지는 등의 문제가 있다.In the present invention, the reason for limiting the spinning speed (speed of the first high roller) to 1,500 to 2,000 m / min is that the spinning speed is too low when the spinning speed is less than 1,500 m / min. In addition, in the case of exceeding 2,000m / min, there is a problem that the dyeability is worsened by the stretching effect and the posture effect decrease.
본 발명에서 제1고뎃롤러의 온도를 40∼60℃로 한정한 이유는 제1고뎃롤러의 온도가 60℃를 초과하면 열열신이 일어나 본 발명과 같은 태세효과를 얻을 수 없으며, 40℃ 미만의 경우 연신시에 절사가 일어나는 등의 문제가 발생되기 때문이다.The reason why the temperature of the first gourd roller is limited to 40 to 60 ° C in the present invention is that when the temperature of the first gourd roller exceeds 60 ° C., thermal heat generation occurs and the posture effect as described in the present invention cannot be obtained. This is because a problem such as cutting occurs during stretching.
또한 제2고뎃롤러의 온도를 50∼70℃로 한정한 이유는 제2고뎃롤러는 열고정하는 역할을 하므로 온도가 50℃ 미만일 경우 열고정의 효과가 없으며, 70℃를 초과하는 경우 고온처리로 인한 태세효과가 감소되는 문제가 있기 때문이다.In addition, the reason for limiting the temperature of the second gourd roller to 50 to 70 ° C is that the second gourd roller plays a role of heat setting, so if the temperature is less than 50 ° C, there is no effect of heat setting. This is because there is a problem that the effect is reduced.
본 발명에서 연신비를 1.7∼2.0으로 한정한 이유는 연신비가 1.7배 미만으로 너무 낮으면 태세효과가 미약하고 또한 연신배율이 너무 낮으므로 인한 원사의 강력저하 등의 문제가 있으며, 연신비가 2.0을 초과하면 태세효과가 오히려 사라지는 문제가 있기 때문이다.The reason for limiting the draw ratio in the present invention to 1.7 to 2.0 is that if the draw ratio is too low, less than 1.7 times, there is a problem such as weak posture effect and the draw ratio is too low, resulting in a strong decrease in yarn, and the draw ratio exceeds 2.0. This is because the posture effect rather disappears.
이하 본 발명을 실시예를 들어 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to Examples.
단, 본 발명이 실시예에 국한되는 것은 아니다.However, the present invention is not limited to the examples.
＜실시예 1＞<Example 1>
고유점도 0.65인 폴리에텔렌테레프탈레이트를 방사속도 2,000m/min으로 방사한 후 통상의 SDY 제조방법과 같이 냉각고화시키고 유제급유에 의해 사조를 집속시키고 온도가 55℃인 제1고뎃롤러와 온도가 60℃인 제2고뎃롤러사이에서 연신배율 1.75로 연신하고 권취하여 태세사를 제조하였다.After spinning the polyetherene terephthalate with an intrinsic viscosity of 0.65 at a spinning speed of 2,000 m / min, it is cooled and solidified as in the usual SDY manufacturing method, and the yarns are concentrated by emulsion oiling. Between the second gourd roller at 60 ° C. was drawn and wound at a draw ratio of 1.75 to prepare a poised yarn.
이렇게 제조된 태세사의 물성을 측정하여 ＜표1＞에 나타내었다.The physical properties of the ready-to-use yarn thus prepared were measured and shown in Table 1.
