본 발명은 제전성이 우수하고 염색성이 향상된 폴리아미드 제전사의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyamide antistatic yarn having excellent antistatic properties and improved dyeability.
지금까지 알려진 폴리아미드 제전사의 제조방법은 대형방사기로 폴리아미드칩과 제전성칩을 혼합한 다음 용융 압출하여 제조하여 왔는 바, 방사기 내에서 제전성칩의 체류시간이 길었기 때문에(10-30분) 내열성이 약한 제전물질의 물성변화나 부반응이 발생하고 이로 인하여 제전성의 약화를 초래하였으며, 동시에 제전성 물질의 불균일한 혼합으로 말미암아 염색차를 유발시키는등의 문제점이 있었다.The known manufacturing method of polyamide electrostatic yarn has been produced by mixing polyamide chips and antistatic chips with a large spinning machine and then melt extruding them, because the residence time of the antistatic chips in the spinning machine was long (10-30). Min) Changes in the physical properties or side reactions of the antistatic material with low heat resistance resulted in weakening of the antistatic property, and at the same time, there was a problem such as causing the difference in dyeing due to uneven mixing of the antistatic material.
본 발명은 제전성물질의 방사기내에서의 체류시간을 최소한으로 함과 동시에 제전성물질의 혼합이 잘되도록 하여서 종래기술의 상기한 바와 같은 문제점을 해결한 것으로서 이하 예시도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the problems as described above in the prior art by minimizing the residence time of the antistatic material in the radiator and at the same time the mixing of the antistatic material is well described as follows. same.
본 발명은 대형 익스트루더(1)에는 순수한 폴리아미드칩을 용융, 압출시키며, 소형 익스트루더(2) 또는 (2')에는 제전성칩을 별도로 용융, 압출되도록 하였다.The present invention melts and extrudes pure polyamide chips in the large extruder 1, and separately melts and extrudes the antistatic chips in the
대형 익스트루너(1)로부터 압출된 순수한 폴리아미드는 주분기관(3)으로 공급되며, 소형 익스트루더(2) 또는 (2')로부터 용융, 압출된 제전성 폴리아미드는 부분기관(4)을 거친 다음에 주분기관(3)에서 순수한 폴리아미드와 합류된다.The pure polyamide extruded from the large extruder 1 is supplied to the main engine 3, and the antistatic polyamide melted and extruded from the
주분기관(3)에는 스테틱믹서(Static mixer)(5)가 내장되어 있기 때문에 이곳을 통과하는 동안에 순수한 폴리아미드와 제선성 폴리아미드는 완전하게 혼합이 된다.Since the main engine 3 has a built-in
이와 같이 균일하게 혼합이 된 용융 폴리머는 스피닝블록(6)을 통하여 방사되는 것이다.The molten polymer thus uniformly mixed is spun through the
본 발명은 제전성 폴리아미드가 소형 익스트루더(2) 또는 (2')를 통하여 용융, 압출되므로 소형 익스트루더(2) 또는 (2')에서의 체류시간이 1-2분 정도 밖에 되지 않게 된다.In the present invention, since the antistatic polyamide is melted and extruded through the
따라서 종래처럼 제전물질의 물성이 변화하거나 부반응의 우려가 없게 되어 제조된 제전사의 제전성이 향상된다.Therefore, there is no possibility of changing the physical properties of the antistatic material or the side reaction as in the prior art to improve the antistatic properties of the manufactured antistatic agent.
아울러 본 발명은 스피닝블럭(6)에 도달하기 전에 두 성분이 스테틱믹서(5)를 거치면서 혼합되기 때문에 종래치럼 두 성분의 불균일한 혼합으로 야기되는 염색차이를 극복할 수 있으며 우수한 염색성을 발휘하게 되는 것이다.In addition, the present invention can overcome the dyeing difference caused by non-uniform mixing of the two components because the two components are mixed while passing through the static mixer (5) before reaching the spinning block (6) and exhibits excellent dyeability Will be done.

상대점도가 2.55±0.05인 폴리아미드를 대형 익스트루더로 용융 압출시키고, 고농도의 제전성 폴리아미드를 소형 익스트루더로 용융, 압출한 다음 이들을 스테틱믹서로 혼합한 후 950m/min로 권취하고 연신하였다.Polyamide having a relative viscosity of 2.55 ± 0.05 is melt-extruded with a large extruder, melted and extruded a high concentration of antistatic polyamide with a small extruder, mixed with a static mixer, and wound up at 950 m / min. Stretched.
방사 연신조건은 아래와 같이 하였다.Radial stretching conditions were as follows.
