도2를 참조하여 상세히 설명하면 다음과 같다.A detailed description with reference to FIG. 2 is as follows.
먼저 본 발명을 개략하여 설명하면 본 발명은 용융혼합방사에의한 초극세사 부직포 인공피혁의 제조장치에 있어서, 가용성 성분을 제거하는 용출과정에서의 용출장치가 용출조영역(A')과 탈용제영역(B')으로 구분되어있고, 용출장치 입출부에 비용제함침욕조(1,2,3)가 설비되어 있는 것을 특징으로 하는 부직포 인공피혁 제조용 용출장치이다.First, the present invention will be briefly described. In the present invention, in the apparatus for producing ultra-fine micro-woven nonwoven artificial leather by melt mixed spinning, the elution apparatus in the elution process for removing the soluble component is the elution tank area (A ') and the desolvent area. An elution device for manufacturing nonwoven artificial leather, which is classified as (B '), and is provided with a cost-impregnation bath (1, 2, 3) at the elution unit.
설비는 부직포 입, 출 과정에서 내부의 강한 독성가스가 외부로 누출되지 않도록 하기위하여 비용제 함침욕조(1,2)를 설치하고 기존 설비에서 문제가 되어왔던 용출의 효율성을 높이기 위하여 각 용출조를 빠져 나가는 피용출물의 상하를 강한 압력의 용제로 충격을 주도록 용제분사 장치(4)를 설치하여 잔존하는 가용성분을 효과적으로 제거한다.In order to prevent strong toxic gas from leaking into the outside during the process of entering and exiting nonwoven fabrics, the installation of non-woven impregnation baths (1, 2) is carried out and each elution tank is used to increase the efficiency of elution which has been a problem in the existing facilities. The solvent spraying device 4 is installed so as to impact the upper and lower parts of the effluent to be discharged with a solvent of a strong pressure to effectively remove the remaining soluble component.
한편, 종래 도1의 장치에서 배기용 휀 (C)을 제거하그 용출조 영역(A')과 탈용제 영역(B') 사이에 비용제함침욕조(3)를 설치하여 용출설비 내부에서의 가스유동을 막고 탈용제영역(B')에서 효과적으로 용제를 제거할 수 있도록 하고 탈용제영역(B')은 비용제로 채우고 피용출물에 일부 묻어 있는 소량의 용제와 비용제를 함께 가열하여 휘발성이 강한 용제를 피용출물에서 완전제거한 뒤 증발되는 용제와 비용제의 혼합가스는 응축장치(5)를 통해 액화시켜 혼합탱크(6)로 모으고 이때 비용제와 용제는 각 용제간의 비중차이로 인해 층분리가 생기게 되어 층별로 두 용제를 분리할 수 있다.On the other hand, in the conventional apparatus shown in Fig. 1, the exhaust fin C is removed, and a non-impregnation bath 3 is provided between the elution tank region A 'and the desolvent region B' to provide a gas inside the elution facility. To prevent the flow and to effectively remove the solvent in the desolvent zone (B '), the desolvent zone (B') is filled with a non-solvent, and a small amount of solvent and non-solvent, which is partially buried in the eluate, are heated together to make a highly volatile solvent. Is completely removed from the eluate, and the mixed gas of the solvent and the non-solvent evaporated is liquefied through the condenser 5 to be collected into the mixing tank 6, where the non-solvent and the solvent are separated due to the difference in specific gravity between the solvents. The two solvents can be separated by layer.
한편, 용출조 영역(A')은 3개의 용출조로 구성되어 있어 제 1 용출조(C'), 제 2용출조(D'), 그리고 제3 용출조(E,)순으로 연속적으로 피 용출물이 지나가면서 가용성분이 완전히 제거되며 제 3용출조(E')의 용제는 다시 제2 용출조(D')르 오버 플로우(Over flow)되며, 제 2용출조(D')의 용제는 다시 제 1용출조(C')로 오버 플로우 되어 각 용출조내의 용제에 대한 가용성분의 농도를 단계적으로 낮게 유지시켜 용출 효과를 극대화 시킨다.On the other hand, the elution tank area A 'is composed of three elution tanks so that the first elution tank C', the second elution tank D ', and the third elution tank E, are successively avoided. As the eluate passes, the soluble component is completely removed and the solvent of the third elution tank E 'is overflowed again to the second elution tank D', and the solvent of the second elution tank D 'is It is overflowed again to the first elution tank (C ') to maximize the elution effect by keeping the concentration of soluble components for the solvent in each elution tank step by step low.
이러한 과정을 거쳐 용출이 완료된 피 용출물에는 인체에 무해한 비용제만 잔류하게 되고 이를 열풍으로 건조시키게 된다. 이후에 염색 및 버핑 등의 표면처리를 거쳐 천연피혁과 유사한 초극세사 부직포 인공피혁을 제조하게 된다.In this process, the eluted eluate is left with only a cost-effective harmless body and dried by hot air. After that, through the surface treatment such as dyeing and buffing to produce a microfiber non-woven artificial leather similar to natural leather.
본 발명에 의한 특수 용출 장치를 이용함으로써 혼합방사를 이용한 초극세사 부직포 인공피혁의 제조에 있어서 0.0005 내지 0.01 데니어수준의 초 극세사 제조가 가능하게 되어 천연피혁과 같은 부직포 인공피혁을 제조할 수 있게 되고, 종래의 이용성 폴리머를 이용한 해도형 극세사의 알칼리감량법에 따른 환경오염을 막을 수 있을 뿐만 아니라 기존 혼합방사섬유의 가용성분을 용출하는 과정에서 강한 독성의 용제가스가 외부로 누출되지 않도록 방지함에 따라 용제 로스(Loss) 절감과 환경오염방지, 작업안정성 향상 등을 꾀할 수 있는 효과가 있다.By using the special elution device according to the present invention in the manufacture of ultra-fine microfibre nonwoven artificial leather using mixed spinning can be made of ultra-fine fibers of 0.0005 to 0.01 denier level can be produced non-woven artificial leather, such as natural leather, It is not only possible to prevent environmental pollution by alkali reduction method of island-in-the-sea microfiber using usable polymer, but also to prevent strong toxic solvent gas from leaking to the outside in the process of eluting the soluble component of existing mixed spinning fiber. It is effective in reducing losses, preventing environmental pollution, and improving work stability.
