장섬유 부직포의 제조방법Manufacturing method of long fiber nonwoven

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 복함섬유의 단면상태도, 제2도는 본 발명에 따른 개략 장치도.1 is a cross-sectional view of the composite fiber according to the present invention, Figure 2 is a schematic device according to the present invention.

Claims (2)

폴리아미드와 폴리에스테르계의 2성분으로 이루어진 분할형 복합섬유를 사용하여 부직포를 제조함에 있어서, 복합섬유의 중심성분은 섬유형성성 폴리에스테르로 구성하되 횡단면의 중심에서 방사상으로 분지시켜 중심부분으로 향하는 4개 이상의 쐐기형으로 하고, 복합섬유의 원주성분은 섬유형성성 폴리아미드로 구성하되 횡단면의 외주부분을 형성함과 동시에 외주부분에서 중심을 향하여 쐐기상으로 분지하여 중심성분과 교호로 배열시킨 구조로 복합 섬유를 방사하고, 이를 롤러연신법에 의해 1.0 내지 1.5배 1차 연신하고 계속해서 코로나방전 처리한 후, 2차로 압축공기를 사용 방사속도 4,000 내지 6,000m/분이 되도록 연신하여 장섬유 부직포 웹을 형성시킨 다음, 이를 카렌더링하여 제조함을 특징으로 하는 장섬유 부직포의 제조방법.In the production of nonwoven fabric using split type composite fiber composed of polyamide and polyester, the central component of the composite fiber is composed of fiber-forming polyester, which is branched radially from the center of the cross section to the central part. It consists of four or more wedges, and the circumferential component of the composite fiber is composed of fiber-forming polyamide, forming the outer circumferential part of the cross section, and branched in the wedge shape from the outer circumferential part toward the center to be arranged alternately with the central component. Spinning the composite fiber in the furnace, and by the roller drawing method, the primary stretching is 1.0 to 1.5 times the primary stretching and then corona discharge treatment, and the secondary fibers are stretched to use the compressed air at a spinning speed of 4,000 to 6,000 m / min, the long-fiber nonwoven web Forming, and then producing a long fiber nonwoven fabric characterized in that it is produced by calendering. 제1항에 있어서, 장섬유 부직포 웹의 카렌더링은 1차로 온도 80 내지 130℃압력 1내지 20N/㎜로 프리본딩하고, 2차로 온도 180 내지 240℃, 압력 30 내지 200N/㎜으로 카렌더링 함을 특징으로 하는 장섬유 부직포의 제조방법The method of claim 1, wherein the calendering of the long-fiber nonwoven web is pre-bonded at a temperature of 80 to 130 ° C pressure 1 to 20 N / mm first, and calendered to a second temperature of 180 to 240 ° C, pressure 30 to 200 N / mm Method for producing a long fiber nonwoven fabric characterized in that ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
