Description
본 발명은 인조피혁 및 고성능필터에 사용되는 폴리에틸렌테레프탈레이트 수지로 제조되는 부직포용 단섬유 및 그의 제조방법에 관한 것이다.The present invention relates to a short fiber for a nonwoven fabric made of polyethylene terephthalate resin used in artificial leather and a high performance filter, and a manufacturing method thereof.
일반적으로 인조피혁이나 고성능필터에 사용되는 단섬유는 극세 해도사를 이용한 단섬유가 많이 사용되었다. 기존 해도사로 인조피혁을 생산시 필수 공정인 알칼리감량 공정에서 물의 소비가 심하고 다량의 폐수가 발생하며 이러한 폐수를 처리하는데 막대한 비용이 소모되고 자연환경에 이롭지 못하기 때문에 물의 많은 소비로 인해 발생하는 폐수와 폐자원을 줄이기 위해서는 물의 사용이 많은 공정에 대한 변화된 인식이 필요하게 되었다. 즉 물의 소비가 심한 공정에서 생략할 수 있는 공정은 생략함으로써 환경오염 등의 문제를 감소하고 제조원가를 낮춰 경쟁력을 가질 수 있는 단섬유의 제조방법이 절실하였다. In general, the short fibers used in artificial leather or high-performance filter was used a lot of short fibers using ultra-fine islands. Alkali reduction process, which is an essential process for producing artificial leather with existing sea islands, consumes a lot of water and generates a large amount of wastewater, and it is expensive to treat such wastewater and it is not beneficial to the natural environment. In order to reduce waste and waste resources, there is a need for changed awareness of water-intensive processes. That is, by eliminating the process that can be omitted in the process of heavy water consumption, the production method of short fibers that can be competitive by reducing problems such as environmental pollution and lowering the manufacturing cost is urgently needed.
또한, 인공피혁을 제조하기 위한 단섬유에 대한 기술개발은 시장개방에 따른 선진국의 시장 확대 및 선진국의 휘발성 유기용제(Volatile Organic Compound(VOC)) 규제에 대응하고 기술경쟁력을 갖추기 위해서도 더욱 그 필요성이 증대된다.In addition, the development of technology for short fibers for manufacturing artificial leather is more necessary to cope with the expansion of the market in developed countries and the regulation of volatile organic solvents (VOC) in developed countries as well as technological competitiveness.

본 발명은 폴리에틸렌테레프탈레이트 수지를 이용하여 분산성이 좋은 부직포용 단섬유의 제조방법에 관한 것으로 도 1의 공정도에서 나타난 바와 같이 방사공정, 캔화공정, 커팅공정으로 제조되고 상기 커팅공정전에 열처리 또는 연신공정이 추가될 수 있다.The present invention relates to a method for producing short fibers for nonwoven fabric having good dispersibility using polyethylene terephthalate resin, as shown in the process diagram of FIG. 1, which is manufactured by a spinning process, a canning process, and a cutting process, and heat treatment or stretching before the cutting process. Process may be added.
상기 방사공정은 고유점도가 0.60~0.80인 폴리에틸렌테레프탈레이트 수지를 구금 홀(홀)당 토출량이 0.15~0.25 g/min으로 방사속도 2000~2,600m/min으로 방사하면서 연신하는 공정으로 상기 연신에서의 연신율은 1.40~2.0으로 연신하면서 방사공정을 실시하여 극세 필라멘트를 얻을 수 있다.The spinning process is a process of spinning a polyethylene terephthalate resin having an intrinsic viscosity of 0.60 to 0.80 while spinning at a spinning speed of 2000 to 2,600 m / min at a discharge rate of 0.15 to 0.25 g / min in a detention hole. The elongation can be extended to 1.40 ~ 2.0, and the fine filament can be obtained by spinning process.
염색성이 균일한 부직포용 극세 단섬유를 생산하기 위해서 방사 공정에서 극세 필라멘트를 생산과 동시에 연신하는 것이 균일한 염색성부여에 효과적이다.In order to produce microfiber short fibers for nonwoven fabric with uniform dyeability, it is effective to impart uniform dyeability in the spinning process at the same time to produce the ultrafine filament.
상기 방사공정에서 구금 홀 수가 너무 많으면 방사시 균일 고화가 어려워 단사 섬유간 섬도 편차가 심하기 때문에 본 발명에서의 구금 홀 수는 100~ 500의 구금 홀수가 바람직할 것이다.In the spinning process, if the number of detention holes is too large, uniform solidification is difficult during spinning, and the fineness variation between single yarn fibers is severe, so that the number of detention holes in the present invention is preferably 100 to 500 detention holes.
상기 방사공정에서의 연신시 연신유제의 부착량이 부족하여 단섬유 표면의 미끄러짐을 방해하여 분산성이 불량해져 제조되는 부직포의 표면이 불균일해질 문제가 있기 때문에 적정량의 연신유제를 필라멘트에 부착하여야한다. 상기 연신유제의 바람직한 부착량은 2,000~2500cc/min를 방사되는 필라멘트에 부착하여 연신하는 것이다.In the spinning process, the amount of the stretching oil is insufficient to prevent slippage of the surface of the short fiber, so that the dispersibility is poor and the surface of the nonwoven fabric is uneven. Therefore, an appropriate amount of the stretching oil should be attached to the filaments. A preferred amount of adhesion of the stretching oil is to stretch 2,000 to 2500cc / min attached to the spinning filament.
상기 캔화공정은 상기 방사된 필라멘트를 캔(CAN)화 설비를 이용하여 캔에 담는 캔화공정으로 방사된 필라멘트를 크릴(creel)에 300~500개 로딩작업 후 캡스턴 롤러(capstan roller)를 이용하여 크릴에 로딩된 원사를 한가닥으로 모아 토우(tow)를 형성시켜 캔에 담아 캔화하는 공정으로 캔화공정으로 단면변동율이 균일한 우수한 필라멘트를 얻을 수 있다. 상기 토우의 총섬도는 80~100만 데니어(denier)로 제조되는 것이 바람직할 것이다.The canning process involves loading 300-500 filaments into a creel by a canning process in which the radiated filaments are contained in a can using a canning facility, and then using a capstan roller. It is a process that collects the yarn loaded in a strand and forms a tow, and puts it in a can and cans can obtain excellent filament with uniform cross-sectional variation. It is preferable that the total fineness of the tow is made from 80 to 1 million deniers.
상기 커팅공정은 상기 캔화공정된 극세 필라멘트를 단섬유로 커팅하여 부직포용 단섬유를 제조한다.The cutting process cuts the canned microfine filament into short fibers to produce short fibers for nonwoven fabrics.
상기 커팅공정전에 상기 캔화공정된 극세 필라멘트를 다시 한번 연신하여 제조되는 단섬유의 섬도를 더욱 균일하게 하고 물성을 향상시키며 단섬유의 분산도를 향시킬 수 있다.또한, 상기 커팅공정전의 연신공정은 1.50~2.0의 연신율로 연신될 수 있을 것이다.Before the cutting process, the canned microfiber filaments are stretched once again to make the fineness of the short fibers more uniform, improve physical properties, and improve the dispersion of the short fibers. It can be stretched at an elongation of 1.50 to 2.0.
또한, 상기 커팅공정은 연신 설비에서 150~230 ℃에서 열처리한 후 커팅하는 것이 분산성 향상에 바람직하며 더욱 바람직하게는 150~200℃에서 열처리를 하는 것이다.In addition, the cutting process is preferably to improve the dispersibility and to cut after heat treatment at 150 ~ 230 ℃ in the drawing equipment is more preferably heat treatment at 150 ~ 200 ℃.
상기의 제조방법으로 제조되는 부직포용 단섬유의 평균섬도는 0.3~0.5 데니어의 범위인 것이 가장 바람직 하며, 섬유장은 롱 컷(long cut)이나 숏 컷(short cut)으로 제조될 수 있으나 3~12 ㎜의 숏 컷형태로 제조되는 것이 바람직할 것이다.The average fineness of the short fibers for nonwoven fabric produced by the above manufacturing method is most preferably in the range of 0.3 ~ 0.5 denier, the fiber length may be produced in long cut (short cut) or short cut (3-12) It would be desirable to produce a short cut in mm.
본 발명의 제조방법은 단사 섬유간 섬도 편차를 줄이기 위하여 구금 홀수가 적은 방사공정에서 방사된 필라멘트를 캔화하여 열처리하거나 연신공정을 추가하거나 열처리, 연신공정을 동시에 하고 커팅공정을 실시하여 상기 방법으로 제조되는 부직포용 단섬유는 단섬유의 섬도가 균일하고 우수한 분산성으로 상기 단섬유로 제조되는 부직포는 우수한 염색성을 가지게 된다.In order to reduce the fineness variation between single yarn fibers, the manufacturing method of the present invention is prepared by the above method by performing a heat treatment or adding a stretching process or simultaneously performing a heat treatment and stretching process by canning the filament spun in a spinning process with a low number of detained odd number. The non-woven short fiber is a non-woven fabric made of the short fiber with excellent fineness and uniform dispersibility of the short fiber has excellent dyeability.
본 발명에 따른 부직포용 단섬유의 제조방법은 단섬유의 섬도를 균일하게 하여 분산성 및 염색성이 우수한 부직포를 제조할 수 있으며, 특히 염색성 및 물성이 우수한 인조피혁을 제조할 수 있는 인조피혁용 부직포를 제조할 수 있을 것이다.According to the present invention, a method of manufacturing short fibers for nonwoven fabrics can produce a nonwoven fabric having excellent dispersibility and dyeability by uniformly making fine fibers, and in particular, a nonwoven fabric for artificial leather which can manufacture artificial leather having excellent dyeing properties and physical properties. It may be prepared.
또한, 종래의 해도사를 이용하여 인조피혁을 생산시 필수 공정인 알칼리감량 공정이 필요치 않아 물의 과소비를 줄일 수 있으며, 폐수를 발생시키지 않아 친환경적인 공법에 의해 인조피혁을 제조할 수 있다.In addition, it is possible to reduce the over-consumption of water because it does not need an alkali reduction process, which is an essential process when producing artificial leather using conventional sea island yarns, and can produce artificial leather by an environmentally friendly method without generating waste water.
