Description

초극세사 부직포 인공피혁의 제조방법Manufacturing method of microfibre nonwoven artificial leather

본 발명은 초극세사 부직포 인공피혁의 제조방법에 관한 것으로, 보다 상세하게는 종래의 초극세사 부직포 인공피혁의 제조방법과 달리, 부직포생지를 용제용출하고 버핑가공한 후 폴리우레탄 함침처리, 염색등 일련의 후가공을 하는 것을 특징으로 하는 표면 입모가 치밀하고 라이팅효과가 우수한 초극세사 부직포 인공피혁의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a microfiber nonwoven artificial leather, and more specifically, unlike a conventional method for manufacturing a microfiber nonwoven artificial leather, after dissolving and buffing the nonwoven fabric, a series of post-processing, such as polyurethane impregnation treatment, dyeing It relates to a method for producing a microfiber nonwoven artificial leather having a compact surface and excellent lighting effect, characterized in that.

종래 극세사 부직포 인공피혁의 제조방법으로는 국내특허 공개번호 제 93-006245호, 90-010138호 등에 나일론 혹은 폴리에스터와 이용성 폴리머를 사용하여 복합방사를 통해 해도형 극세사 스테이플 섬유를 제조하여 니들펀칭으로 부직포 펠트를 만든 뒤 알칼리 수용액으로 이용성 폴리머를 제거하여 구성섬유를 극대화 시키는 방법이 제안되어 있다.Conventional methods for manufacturing microfibre nonwoven artificial leather include needle-punching by producing island-in-the-sea microfiber staple fibers through composite spinning using nylon or polyester and a usable polymer in Korean Patent Publication Nos. 93-006245 and 90-010138, etc. A method of maximizing the constituent fiber by making a nonwoven felt and then removing the usable polymer with an aqueous alkali solution has been proposed.

또한, 국내특허 공개번호 제 95-58496에는 복합방사 타입이 아닌 일반 혼합방사 타입으로 폴리블렌드 초극세 섬유를 제조한 후 폴리우레탄 함침후 용제용출하는 공정으로 초극세사 인공피혁을 제조하는 방법을 제안하고 있다.In addition, Korean Patent Publication No. 95-58496 proposes a method for producing an ultra-fine artificial artificial leather by a process of preparing a polyblend ultra-fine fibers in a general mixed spinning type, not a composite spinning type, and then dissolving the solvent after polyurethane impregnation.

그러나, 이와 같은 복합방사 타입의 종래의 부직포 인공피혁의 제조방법은 단사섬도 0.01데니어 이하의 초극세사 부직포 인공피혁 제조가 실질적으로 불가능하고, 또한 혼합방사 타입의 폴리블렌드 초극세사 부직포의 경우도 후용출방식으로는 치밀한 표면입도 밀도, 고른표면 및 양호한 라이팅효과를 거둘 수 없는 문제점이 있다. 물론, 복합방사타입의 극세 부직포 제조방법으로 알칼리 용출후 폴리우레탄 탄성체 용액을 함침시키는 이른바 선용출타입의 제조방법이 있으나, 상술한 바와 같이 복합방사 타입의 부직포 제조방법으로는 0.01 데니어 이하의 초극세사 부직포 제조가 불가능하게 된다.However, the conventional method of manufacturing a composite spinning type nonwoven artificial leather is practically impossible to manufacture a microfiber nonwoven artificial leather having a single yarn fineness of 0.01 denier or less, and also in the case of a mixed spinning type polyblend microfiber nonwoven fabric by a post-dissolution method. There is a problem that can not achieve a dense surface particle density, even surface and good lighting effect. Of course, there is a so-called pre-dissolution type manufacturing method of impregnating a polyurethane elastomer solution after alkali elution as a method of manufacturing a fine spinning nonwoven fabric of a composite spinning type, but as a method of manufacturing a non-woven fabric of a composite spinning type non-woven fabric of 0.01 denier or less Manufacturing becomes impossible.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 표면 입모가 치밀한 초극세사 부직포 인공피혁의 제조방법을 제공하고자 하는 것이다.An object of the present invention is to devise to solve the above-mentioned conventional problems, to provide a method for producing a super-microfiber nonwoven artificial leather with dense surface hair.

즉, 본 발명은 폴리아미드 혹은 폴리에스테르를 제 1성분(섬유성분)으로 하고, 융점 120℃ 이하의 폴리에틸렌, 혹은 폴리스티렌을 제 2성분(피용출성분)으로 한 혼합방사를 통해 제 2성분을 용출 제거후 제 1성분이 0.01데니어 이하의 섬도를 갖는 초극세사 단섬유를 이용하여 오프닝, 카아딩, 크로스래핑 및 니들펀칭을 통해 부직포 펠트를 제조하고, 고점도 폴리비닐알콜 수용액으로 전처리하고, 폴리우레탄 탄성체를 처리한 피혁상 시트물을 염색하고 버핑하여 초극세사 부직포 인공피혁을 제조함에 있어서, 기존 공정과 달리 부직포 펠트를 폴리우레탄 탄성체 용액을 처리하기 전에 먼저 적당한 용제로 섬유 제 2성분을 제거한다. 그후 고점도 폴리비닐 알콜 수용액으로 처리한 후 90 내지 110℃의 가열된 실린더롤로 부직포 펠트 두께의 일정두께로 눌러주어 다시 실린더로 드라잉하고 일정규격의 샌드페이퍼로 버핑가공한다. 그리고 폴리우레탄 함침처리, 염색, 버핑, 모미등 일련의 후가공을 거침으로써 표면 입모가 치밀하고 고른 라이팅 효과를 가지는 초극세사 부직포 인공피혁의 제조방법에 관한 것이다.That is, in the present invention, the second component is eluted through mixed spinning using polyamide or polyester as the first component (fiber component) and polyethylene having a melting point of 120 ° C. or lower, or polystyrene as the second component (elution component). After removal, non-woven felts were prepared by opening, carding, cross-lapping and needle punching using ultra-fine short fibers having a fineness of 0.01 denier or less, and pre-treated with a high viscosity polyvinyl alcohol aqueous solution. In manufacturing the microfiber nonwoven artificial leather by dyeing and buffing the treated leather sheet, unlike the conventional process, the fiber second component is first removed with a suitable solvent before the nonwoven felt is treated with the polyurethane elastomer solution. After treatment with a high viscosity polyvinyl alcohol aqueous solution and then pressed to a certain thickness of the non-woven felt thickness with a heated cylinder roll of 90 to 110 ℃ to drive again into the cylinder and buffing with a sandpaper of a certain standard. In addition, the present invention relates to a method for producing an ultra-fine nonwoven artificial leather having a dense and even lighting effect by performing a series of post-processing such as polyurethane impregnation treatment, dyeing, buffing, and woolening.

이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명에서의 원사제조 방법으로는 폴리아미드 혹은 폴리에스테르 50 내지 70중량%를 제 1성분(섬유성분)으로 하고, 융점 120℃이하, 용융지수 40 내지 80g/10min의 폴리에틸렌 혹은 폴리스티렌 30 내지 50중량%를 제 2성분(피용출성분)으로 한 혼합방사를 통해 초극세사를 제조하고 용도에 따라 섬유성분 대비 0.5 내지 5중량%의 카본블랙을 폴리아미드나 폴리에스테르 칩에 첨가하여 마스터배치 칩을 제조하고, 이 마스터배치 칩 1 내지 10%와 일반 폴리아미드나 폴리에스테르 칩을 블렌딩하여 제 1성분으로 하고, 폴리에틸렌 혹은 폴리스티렌으로 된 제 2성분을 혼합방사하여 원착사로 제조한다.In the yarn production method of the present invention, 50 to 70% by weight of polyamide or polyester is used as the first component (fiber component), and the melting point is 120 ° C or lower, and the polyethylene or polystyrene having a melt index of 40 to 80 g / 10 min is 30 to 50 weight. Ultra-fine yarn is manufactured through mixed spinning using% as the second component (elution component), and 0.5 to 5% by weight of carbon black is added to the polyamide or polyester chip according to the use to prepare the masterbatch chip. 1-10% of this masterbatch chip and a general polyamide or polyester chip are blended to form a first component, and a mixed component of a second component made of polyethylene or polystyrene is spun to prepare a primary yarn.

혼합방사한 원사를 단섬유는 3 내지 5데니어의 섬도를 유지하고, 길이 45 내지 60mm, 권축수는 단위길이(인치)당 15 내지 20개이고, 강도가 2 내지 4g/d, 신도는 60 내지 100%가 되도록 한 후 오프닝, 카아딩, 크로스래핑 및 니들펀칭을 통해 중량 500 내지 700g/㎡, 두께 1.8 내지 2.2mm, 펀칭밀도 2,500회/㎠, 밀도 0.20g/㎤ 이상인 고밀도의 부직포 펠트를 제조한다. 이 펠트를 80 내지 100℃ 범위의 온도, 1 내지 5m/min의 속도로 열실린더 처리하여 펠트표면을 평활하게 한다. 이때, 열실린더 압착으로 인한 부직포 펠트의 두께 감소율이 최대 30% 이내이어야 한다. 이후 #220 샌드페이퍼를 이용하여 표면 버핑을 한다.The short fibers of the mixed spun yarns maintain fineness of 3 to 5 denier, the length is 45 to 60 mm, the number of crimps is 15 to 20 per unit length (inch), the strength is 2 to 4 g / d, and the elongation is 60 to 100. The non-woven felt of 500 to 700 g / m 2, thickness 1.8 to 2.2 mm, punching density 2,500 times / cm 2, density 0.20 g / cm 3 or more is prepared through opening, carding, cross lapping and needle punching. . The felt is heat-cylindered at a temperature in the range of 80 to 100 ° C. at a rate of 1 to 5 m / min to smooth the felt surface. At this time, the thickness reduction rate of the nonwoven felt due to heat cylinder compression should be within 30% at most. The surface is then buffed using # 220 sandpaper.

표면버핑한 펠트를 고형분 30 내지 40%의 에스테르-에테르 계통의 폴리우레탄 용액을 디메틸포름아미드에 용해시킨 12 내지 20%의 용액에 함침, 응고 및 건조시킨다. 그리고 나서 다시 #320의 샌드페이퍼로 표면버핑을 하고 건식 모미처리한 후 함금속 산성염료를 사용하여 염색하고 고착처리, 대전방지제 및 유연가공한 다음 다시 #400의 샌드페이퍼를 사용하여 표면 버핑하고 슬라이싱 가공을 통해 0.005 내지 0.001데니어의 초극세사 부직포 인공피혁을 제조한다.The surface-buffed felt is impregnated, solidified and dried in a solution of 12 to 20% in which a solution of a polyurethane of an ester-ether system having a solid content of 30 to 40% is dissolved in dimethylformamide. The surface is then buffed with # 320 sandpaper, dried and momified, then dyed with an acidic metal-containing dye, followed by fixation, antistatic and soft working, followed by surface buffing and slicing with sandpaper # 400. Through ultra-fine non-woven artificial leather of 0.005 to 0.001 denier is manufactured.
