Conventional ultrafine composite fibers using polytrimethylene include those disclosed in Korean Patent Laid-Open Publication Nos. 1999-0076028 and 1990-0076036, but these are decomposed by using polyethylene or copolyester as a second component other than PTT. When polyethylene is used as a powder, the difference in melting temperature between polyethylene terephthalate or polytrimethylene, which is an island component, is so large that the melt viscosity difference between island and sea components is large, resulting in poor spin processability. There is a further disadvantage.

It provides an ultra-fine polytrimethylene terephthalate composite fiber for artificial leather, characterized in that the A / B ratio is 40/60 to 90/10 weight ratio.
또한, 본 발명은 고유점도 0.8∼1.2인 폴리트리메틸렌 테레프탈레이트(PTT)를 매트릭스 성분(A)으로 하고, 고유점도 0.4∼0.7인 알카리 이용성 폴리에스테르를 용해 성분(B)으로 하여 각각 압출기로 A/B 비율을 40/60∼90/10 중량비 비율로 용융압출하여 방사용 블록으로 공급한 후 방사팩의 분배판에서 혼합하여 연신비 1.5~3.5, 방사권취속도 2,500~5,000m/min로 하여 방사하며, 방사과정 중 연신 열처리를 가하여 원사를 제조한 뒤 알카리 처리하여 되며, 섬도가 0.1~0.001데니어이고, 감량 후에 감량전 원사의 강도 유지율이 90%이상인 것을 특징으로 하는 인공피혁용 초극세 폴리트리메틸렌 테레프탈레이트 복합섬유의 제조 방법을 제공한다.

이하, 본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.
본 발명은 섬유 형성성 매트릭스 성분인 폴리트리메틸렌 테레프탈레이트와 이용성 성분인 이용성 폴리에스테르를 각각 압출기를 사용하여 일정비율로 균일하게 방사용 블록으로 공급한 뒤 방사팩의 분배판에서 균일하게 혼합하여 토출공을 통하여 방사하며 방사과정 중에 연신 열처리를 가하여 원사를 제조한 뒤 알카리를 사용하여 이용성 폴리에스테르를 용해함으로서 섬도가 0.1~0.001 데니어인 인공피혁용 폴리트리메틸렌테레프탈레이트(이하, "PTT"라 함) 복합섬유에 관한 것이다. 여기서, 상기 이용성 폴리에스테르는 주성분이 폴리에틸렌 테레프탈레이트에 폴리에틸렌글리콜 또는 5-소디움술포이소프탈산 또는 이들의 혼합물 3~20 몰%를 공중합한 것이다.According to the present invention, polytrimethylene terephthalate, a fiber-forming matrix component, and a water-soluble polyester, which are water-soluble components, are each uniformly supplied to a spinning block at a predetermined ratio using an extruder, and then uniformly mixed in a distribution plate of a spinning pack and discharged. Polytrimethylene terephthalate for artificial leather (hereinafter referred to as "PTT") having a fineness of 0.1 to 0.001 denier by dissolving the usable polyester by using alkali, after spinning through a ball and stretching heat treatment during the spinning process. ) Relates to a composite fiber. Here, the usable polyester is obtained by copolymerizing polyethylene terephthalate with polyethylene glycol or 5-sodium sulfoisophthalic acid or a mixture of 3 to 20 mol% thereof.
본 발명의 2성분계 복합섬유는 통상의 복합 방사용 방사장치에 부착된 압출기를 사용하여 PTT와 이용성 폴리에스테르를 각각 용융 압출하여 각각의 기어펌프를 통하여 일정비율로 토출시키고 방사팩의 분배판에서 혼합하여 토출공을 통하여 방사하고, 연신 열처리를 가하여 연신사를 제조하면 PTT 성분이 이용성 폴리에스테르 내에 섬유 축방향을 향하여 배열되어 있는 단면 형태의 복합 섬유를 제조한다. 이때 이용성 폴리에스테르가 PTT 극세 섬유를 둘러싸고 있는 형태를 보이며 용융된 매트릭스 성분(A)과 용해 성분(B)의 비율은 용해성분을 알카리로 용해하였을 때 발현되는 매트릭스 성분의 섬도 및 작업성을 고려하였을 때 A/B 비율은 40/60~90/10 중량비가 적절하고 바람직하게는 60/40~80/20 중량비인 것이 더욱 좋다. 이때, 상기 용해성분의 비율이 60을 초과하면 섬도 범위를 낮출 수 있으나 용해되는 중량 비율이 높기 때문에 알카리를 과량 소비해야 하는 단점이 있고, 10미만으로 하여 원사를 제조하게 되면 섬도 범위가 높아져 인공피혁의 촉감이 딱딱해 지는 단점이 있다. 또한, 제조된 원사의 해성분 감량 후 강도 저하를 막기 위해 각 성분을 압출하는 압출기 온도와 방사 온도를 제어하므로써 원사 감량 후 강도 저하를 막을 수 있다. 이때, 압출기의 온도는 245 ~ 285℃인 것이 바람직하고, 방사온도는 250 ~ 285℃인 것이 바람직하다. 만일 상기 압출기의 온도가 245℃미만일 경우 불완전 용융이 발생하는 단점이 있고, 285℃을 초과할 경우에는 고열로 인한 열분해가 일어나 분자량이 저하하는 단점이 있다. 또한, 상기 방사온도가 250℃미만일 경우 방사 공정성이 불량한 단점이 있고, 285℃을 초과할 경우에는 최종 원사의 물성이 저하하는 단점이 있다.The two-component composite fiber of the present invention is melt-extruded PTT and usable polyester, respectively, using an extruder attached to a conventional spinning machine for spinning, and discharged at a constant rate through each gear pump and mixed in a distribution plate of a spinning pack. When the yarn is produced by spinning through the discharge hole, and the stretching heat treatment is applied to produce a stretched yarn, a composite fiber having a cross-sectional shape in which the PTT component is arranged in the fiber axial direction in the usable polyester is produced. At this time, the usable polyester showed a form surrounding the PTT microfiber, and the ratio of the molten matrix component (A) and the dissolving component (B) was considered considering the fineness and workability of the matrix component that is expressed when the dissolved component is dissolved with alkali. When the A / B ratio is 40/60 ~ 90/10 weight ratio is appropriate, preferably 60/40 ~ 80/20 weight ratio. At this time, if the ratio of the dissolved components exceeds 60, the fineness range can be lowered, but there is a disadvantage in that excessive consumption of alkali is required because the weight ratio is high, and if the yarn is manufactured with less than 10, the fineness range is increased and artificial leather There is a disadvantage that the touch becomes hard. In addition, by controlling the extruder temperature and the spinning temperature for extruding each component in order to prevent the reduction in strength after sea component loss of the manufactured yarn, it is possible to prevent the strength decrease after yarn reduction. At this time, it is preferable that the temperature of an extruder is 245-285 degreeC, and a spinning temperature is 250-285 degreeC. If the temperature of the extruder is less than 245 ° C., there is a disadvantage in that incomplete melting occurs, and if it exceeds 285 ° C., there is a disadvantage in that the molecular weight is lowered due to thermal decomposition due to high heat. In addition, if the spinning temperature is less than 250 ℃ has a disadvantage of poor spinning processability, if it exceeds 285 ℃ has the disadvantage of lowering the physical properties of the final yarn.
