Abstract

The method whose spinning speed is more than 5,500 m/min comprises: passing the fiber strands, which are passed sequentially through the shroud heater, the quench chamber, the heat box and the first godet roller, several times between the second godet roller whose temp. is 120-220 deg.C and the separating roller; and then passing them through the third godet roller whose surface speed is slower by 1-15 % than the second godet roller. By this method, stable and good shaped fiber package can be obtained without forming the hairiness and the fiber breakage even at the high spinning speed exceeding 5,500 m/min.

본 발명은 방사속도 4,500/min 이상으로 고속방사하여 폴리에스테르 섬유를 연속제조할 때 양호한 형태의 팩키지를 얻을 수 있도록 하는 고속방사법에 의한 폴리에스테르 섬유의 제조방법에 관한 것이다.The present invention relates to a method for producing a polyester fiber by a high-speed spinning method to obtain a package of a good shape when the polyester fiber is continuously spun at a spinning speed of at least 4,500 / min.

좀 더 자세히 설명하면, 종래의 영국특허 2002680A에서는 제1도에 예시한 바와 같이 가열통(3)에서 열처리된 사조가 그 내부 분자쇄의 응력 완화(STRESS RELAXATION)로 내부 분자쇄를 안정시킬 수 있는 시간적여유가 없기 때문에, 권취된 사조는 팩키지 내부에서 응력완화가 발생하며, 그 결과 팩키지의 중층부분이 솟아오르는 벌지(Bulge)현상이 발생되어서 취급 및 운송시에 사층이 무너지고 해사성불량의 원인이 된다.In more detail, in the conventional British Patent 2002680A, yarns heat-treated in the heating vessel 3, as illustrated in FIG. 1, can stabilize the inner molecular chains by STRESS RELAXATION of the inner molecular chains. Due to the lack of time, the wound thread causes stress relaxation inside the package, resulting in a bulge phenomenon in which the middle part of the package rises, resulting in collapse of the four layers during handling and transportation and causes of maritime defects. Becomes

본 발명은 종래기술의 상기한 바와 같은 문제점을 해결한 것으로서 본 발명의 목적은 권취속도 4,500/min 이상, 좀 더 구체적으로 설명하면 권취속도 5,500/min 이상의 고속에서도 모우와 절사가 없이 안정된 상태로 균일한 팩키지 형상을 이룰 수 있도록 하는 폴리에스터 섬유의 제조방법을 제공하는데 있다.The present invention solves the problems as described above of the prior art, the object of the present invention is a winding speed of 4,500 / min or more, more specifically, the winding speed 5,500 / min or more even in high speed or more even in a stable state without shear and cutting It is to provide a method for producing a polyester fiber to achieve a package shape.

본 발명을 예시도면에 의하여 상세히 설명하면 다음과 같다.The present invention will be described in detail by way of example.

방사블록(1)에서 토출된 사는 사조의 급격한 냉각을 지연시켜 주는 셔라우드 히터(12)를 통과한 다음 켄취챔버(2)에서 냉각되고 가열통(3)에서 열처리를 받은 다음에 제1고뎃로울러(5), 제2고뎃로울러(6)과 제3고뎃로울러(10)을 거쳐서 권취팩키지(11)로 권취된다.The yarn discharged from the spinning block 1 passes through the shroud heater 12 which delays the rapid cooling of the yarn, and then is cooled in the quench chamber 2 and heat-treated in the heating chamber 3, followed by the first gourd roller. (5), it is wound by the winding package 11 via the 2nd high roller 6 and the 3rd high roller 10. As shown in FIG.

이때 본 발명은 제2도에 도시한 바와 같이 제2고뎃로울러(6)의 하부에 세퍼레이터 로울러(9)를 설치하여서 주행하는 사조를 로울러에 수회 감아서 내부 분자쇄의 응력완화를 진행시켜 줌과 동시에 제2고뎃로울러(6)의 온도를 올려서 사조의 내부 분자쇄가 더 이상의 응력완화 현상을 일으키지 못하도록 분자쇄를 고정시키는 역할을 수행토록 한다.In this case, as shown in FIG. 2, the separator roller 9 is installed at the lower part of the second roller roller 6 so as to wind the thread which is driven several times on the roller to advance the stress relaxation of the internal molecular chain. At the same time, by raising the temperature of the second high roller (6) serves to fix the molecular chain so that the internal molecular chain of yarn thread does not cause any further stress relaxation phenomenon.

이어서 본 발명은 제3고뎃로울러(10)를 제2고뎃로울러(6) 다음에 설치하고 제3고뎃로울러(10)의 표면속도를 제2고뎃로울러(6)의 표면속도보다 약간 느리게 하여서 재차 사조의 내부분자쇄가 응력완화가 되도록 한다.Subsequently, the present invention installs the third high roller 10 after the second high roller 6 and makes the surface speed of the third high roller 10 slightly slower than the surface speed of the second high roller 6. Let the internal molecular chain of the stress relief be.

본 발명에서 제2고뎃로울러(6)의 온도는 120℃∼220℃, 더욱 좋기로는 130℃∼180℃가 좋으며, 제3고뎃로울러(10)의 표면속도는 제2고뎃로울러(6)을 기준하여 1∼15%, 더욱 좋기로는 2∼8% 낮게 설정하는 것이 바람직하다. 이렇게 처리되어 5,500/min 이상의 고속으로 권취되어진 팩키지는 사의 내부구조가 극히 안정하여 팩키지 상에 적층되더라도 종래처럼 팩키지 내부에서의 응력완화 현상으로 인한 사조의 수축작용에 의하여 팩키지의 중간부분이 솟아오르는 소위 벌지(Bulge)현상이 발생되지 않으므로 권취형태가 양호한 팩키지를 얻을 수 있다.In the present invention, the temperature of the second high roller (6) is 120 ℃ to 220 ℃, more preferably 130 ℃ to 180 ℃ is good, the surface speed of the third high roller (10) is the second high roller (6) It is preferable to set as low as 1 to 15%, more preferably as low as 2 to 8%. In this way, the package wound at a high speed of 5,500 / min or more is so stable that even if the internal structure of the yarn is stacked on the package, the middle part of the package rises due to the shrinkage action of the yarn due to the stress relaxation phenomenon in the package as before. Since a bulge phenomenon does not occur, a package having a good winding shape can be obtained.

고유점도가 0.65인 폴리에틸렌 테레프탈레이트를 모세공의 길이가 0.4mm이고 지름이 0.2mm, 모세공의 수가 36개인 구금을 통해 방사하였다. 이때 방사온도는 294℃이고 방사속도는 5,500/min으로 하면서 최종 팩키지에 권취되는 사의 삼도가 75데니어가 될 수 있도록 토출량을 조정하였다.Polyethylene terephthalate having an intrinsic viscosity of 0.65 was spun through a cap with a length of 0.4 mm, a diameter of 0.2 mm and a number of 36 capillaries. At this time, the spinning temperature was 294 ℃ and the spinning speed was 5,500 / min while the discharge amount was adjusted so that the three degrees of yarn wound in the final package can be 75 denier.

켄취챔버(2)의 냉각공기 흐름의 선속도(LINEAR VELOCITY)는 25m/min으로 고정하였다.LINEAR VELOCITY of the cooling air flow in the quench chamber 2 was fixed at 25 m / min.

The temperature of the heating cylinder 3 was adjusted based on the temperature of the heating cylinder inner wall surface.

제2고뎃로울러(6)와 세퍼레이터 로울러(9)에서의 사조의 권회수는 7.5회로 하였다.The number of turns of the yarns in the second roller roller 6 and the separator roller 9 was 7.5 times.

권취팩키지의 트래버스 스트로크 폭은 140mm이고 팩키지의 지름은 350mm까지 권취하였다.The traverse stroke width of the winding package was 140 mm and the diameter of the package was wound up to 350 mm.
