Generally, suede artificial leather is (i) mixed spinning and stretching sea component and island component polymer to produce a composite fiber having a single yarn fineness of 3 to 5 denier levels, and (ii) imparting crimp to these composite fibers and then cutting them. Short fibers (staples) are prepared, and (iii) the staples are three-dimensionally interlaced by a process such as carding and needle punching to produce a nonwoven fabric, and (iii) the nonwoven fabric is shrunk and then padded in an aqueous polyvinyl alcohol solution to form a shape. Stabilized, (iii) impregnating the polyurethane solution therein to prepare a polyurethane impregnated cloth having elasticity, and (iii) extracting and removing the sea component in the impregnated cloth with an aqueous solution of caustic soda, thereby minimizing the fibers, (Iii) The impregnated fabric is prepared by buffing and dyeing it.
그러나 상기 방법은 버핑 공정에서 형성된 입모가 염색 공정에서 탈락하는 문제가 있고, 버핑된 폴리우레탄 함침 기재의 주름 때문에 염색 얼룩이 발생하여 제품의 외관이 손상된다.However, the method has a problem that the hair formed in the buffing process is eliminated in the dyeing process, the staining occurs due to the wrinkles of the buffed polyurethane impregnated substrate to damage the appearance of the product.
따라서 염색시 염색 얼룩이 발생되지 않고 입모가 탈락되지 않아 외관이 우수한 스웨드조 인공피혁을 제조할 수 있는 방법의 개발이 요구되어 왔다. Therefore, there has been a demand for the development of a method that can produce suede-like artificial leather having excellent appearance because no dyeing stain is not generated and hair loss does not occur during dyeing.

본 발명은 외관이 우수한 스웨드조 인공피혁의 제조 방법에 관한 것이다. The present invention relates to a method for producing suede artificial leather excellent in appearance.
더욱 구체적으로 본 발명은 극세섬유 형성 성분과 용출 성분으로 구성된 복합 섬유들이 교락된 부직포에 폴리우레탄 용액을 함침한 다음, 상기 용출 성분을 추출하고, 버핑 및 염색하여 스웨드조 인공피혁을 제조함에 있어서, 염색 공정전에 버핑된 폴리우레탄 함침 기재를 열처리함을 특징으로 하는 스웨드조 인공피혁의 제조 방법에 관한 것이다.More specifically, the present invention impregnated with a polyurethane solution in a nonwoven fabric interwoven with a composite fiber composed of a microfiber forming component and an eluting component, and then extracting the eluting component, buffing and dyeing to produce a suede artificial leather, It relates to a suede-like artificial leather manufacturing method characterized in that the heat-treated polyurethane impregnated substrate before the dyeing process.
이하 본 발명을 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in detail.
먼저, 극세섬유 형성 성분 폴리머와 용출 성분 폴리머를 혼합 방사 및 연신하여 단사섬도가 3∼5 데니어인 복합 섬유를 제조한 다음 권축을 부여하고 절단하여 복합 섬유 스테이플을 제조한다. 이때 극세섬유 형성 성분 폴리머로는 폴리아미드 수지 등을 사용하고 용출 성분 폴리머로는 공중합 폴리에스테르 등을 사용하는 것이 바람직하다. 복합 섬유 스테이플의 권축수는 10∼25개/인치, 길이는 30∼200㎜ 정도로 하는 것이 바람직하다.First, a fine fiber forming component polymer and an eluting component polymer are mixed and spun to prepare a composite fiber having a single yarn fineness of 3 to 5 deniers, and then crimped and cut to prepare a composite fiber staple. At this time, it is preferable to use polyamide resin etc. as an ultrafine fiber formation component polymer and copolyester etc. as an elution component polymer. It is preferable that the number of crimps of a composite fiber staple is 10-25 pieces / inch, and length is about 30-200 mm.
본 발명에서는 극세섬유 형성 성분 및 용출 성분의 폴리머 종류, 단사섬도, 복합 섬유 스테이플의 권축수 및 길이를 특별하게 한정하는 것은 아니다. In the present invention, the polymer type, single yarn fineness, and crimp number and length of the composite fiber staples of the ultrafine fiber forming component and the eluting component are not particularly limited.
다음으로는 복합 섬유 스테이플을 개섬, 카딩 및 니들 펀칭 공정으로 3차원 교락시켜 부직포를 제조한다. 부직포의 중량, 후도, 겉보기 밀도 등은 용도에 따라 적절하게 조절한다.Next, the nonwoven fabric is produced by three-dimensional entanglement of the composite fiber staples in the opening, carding, and needle punching processes. The weight, thickness, apparent density, and the like of the nonwoven fabric are appropriately adjusted according to the use.
다음으로는 상기 부직포를 폴리비닐알코올 수용액에 패딩, 건조하여 형태를 안정화 시킨다.Next, the nonwoven fabric is padded with polyvinyl alcohol aqueous solution and dried to stabilize the shape.
계속해서 상기 부직포에 폴리우레탄 용액을 함침시킨 후 응고, 수세, 건조한다. 이때 폴리우레탄 용액으로는 폴리에테르계 폴리우레탄의 디메틸포름아마이드 수용액 등을 사용한다. 부직포 대비 폴리우레탄의 함침비는 60∼70 : 40∼30 정도의 수준으로 하는 것이 바람직하다. Subsequently, the nonwoven fabric is impregnated with a polyurethane solution, and then coagulated, washed with water and dried. At this time, a dimethylformamide aqueous solution of polyether polyurethane is used as the polyurethane solution. The impregnation ratio of the polyurethane relative to the nonwoven fabric is preferably about 60 to 70:40 to 30.
폴리우레탄이 함침된 부직포를 가성소오다 수용액등으로 부직포내 용출 성분을 용출시켜 복합 섬유들을 극세화 시킨다. 구체적으로 10∼15% 정도 가성소오다 수용액에서 5∼10분 정도 연속적으로 감량 가공한 후 물로 수세 건조한다.Polyurethane-impregnated nonwoven fabrics are eluted with elution components in nonwoven fabrics with a caustic soda solution to minimize the composite fibers. Specifically, after weight loss processing for about 10 to 15% in a sodium hydroxide aqueous solution for 5 to 10 minutes continuously, washed with water and dried.
다음으로 극세화된 기재를 버핑기로 버핑하고, 염색전에 열처리한 다음 염색하여 스웨즈조 인공피혁을 제조한다.Next, the micronized substrate is buffed with a buffer, heat treated before dyeing, and then dyed to prepare a suede artificial leather.
본 발명은 버핑시 형성된 입모의 셋팅(Setting) 및 기재의 주름 제거를 위해 버핑 공정과 염색 공정사이에 열처리함을 특징으로 한다. 본 발명에서 열처리는 140℃∼180℃에서 1분∼3분간 실시하는 것이 바람직하다.The present invention is characterized in that the heat treatment between the buffing process and the dyeing process in order to set the buffing formed during the buffing and to remove wrinkles of the substrate. In this invention, it is preferable to perform heat processing for 1 minute-3 minutes at 140 degreeC-180 degreeC.
만약 열처리 온도가 140℃ 미만이거나 열처리 시간이 1분 미만인 경우에는 입모의 셋팅이 불충분하여 염색 공정중 입모의 탈락이 발생하게 되고 폴리우레탄 함침 부직포의 주름이 제거되지 않아서 염색 얼룩이 발생할 수도 있다.If the heat treatment temperature is less than 140 ℃ or the heat treatment time is less than 1 minute, the setting of the hair is insufficient to cause the fall of the hair during the dyeing process, the wrinkles of the polyurethane impregnated nonwoven fabric may not be removed, staining stain may occur.
또한 열처리 온도가 180℃를 초과하거나 열처리 시간이 3분을 초과하는 경우에는 입모가 과다하게 셋팅되어 입모가 짧게 형성되거나 극세섬유 형성 성분 폴리머의 결정 영역 증가로 염착성이 나빠져 컬러 톤(Color tone)이 너무 옅게된다.In addition, when the heat treatment temperature exceeds 180 ° C. or when the heat treatment time exceeds 3 minutes, the hairs are set excessively, and the hairs are formed shortly, or due to the increase in the crystal area of the ultrafine fiber-forming component polymer, the coloration is poor. Too thin.
열처리는 버핑된 기재를 가열쳄버내로 통과시키는 방식 등으로 실시할 수 있다.The heat treatment may be performed by passing the buffed substrate into a heating chamber.
본 발명은 버핑공정 후에 적절한 열처리로 입모를 셋팅함과 동시에 기재의 주름을 제거하므로서 염색시 입모가 탈락하거나 염색 얼룩이 발생하는 것을 방지할 수 있다. 그 결과 본 발명의 방법으로 제조한 스웨드조 인공피혁의 외관이 향상된다. The present invention can be set to the heat treatment after the buffing process and at the same time to remove the wrinkles of the base material to prevent the falling off of the hair during the dyeing or staining occurs. As a result, the appearance of the suede artificial leather produced by the method of the present invention is improved.
