Abstract

본 발명은 강도 9.5g/d 이상인 고강력 나이론-46 섬유의 제조방법임.The present invention is a method for producing a high strength nylon-46 fiber having a strength of 9.5 g / d or more.

본 발명은 분자쇄의 전체 반복단위가 90몰%인 폴리(테트라메틸렌아디프아미드)를 용융압출방사한 다음 연신, 열처리하여 나이론-46 섬유를 제조할때 스핀블록내의 폴리머온도를 260∼290℃로 유지시킴으로서 적정한 방사팩압력하에서 방사되도록 하여 방사성이 개선된 고강력 나이론-46 섬유를 제조할 수 있도록 한 것이다.In the present invention, the polymer temperature in the spin block is 260 to 290 ° C when melt-extruding poly (tetramethyleneadipamide) having 90 mol% of the total repeating units of the molecular chain, followed by drawing and heat treatment. By maintaining it in the form of a high-strength nylon-46 fiber with improved spinning property by spinning under an appropriate spinning pack pressure.

본 발명은 고강력 나이론-46 섬유는 타이어코드용으로 적합하다.The high strength nylon-46 fibers of the present invention are suitable for tire cords.
