Description
본 발명은 수성 폴리우레탄 수지를 이용하여 직, 편물 및 부직포와 같은 포지를 함침가공하여 합성피혁을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing synthetic leather by impregnating forge such as woven, knitted and nonwoven fabrics using an aqueous polyurethane resin.
기존의 용제형 폴리우레탄 수지 조성물을 함침시키고 상면에 수지 조성물을 도포하여 은면층을 형성시키고, 은면층의 표면을 연마하거나 엠보싱하여서 천연피혁과 유사한 촉감과 기능성을 부여하였다. 이러한 용제형 수지를 사용하여 합성피혁을 제조하는 경우 유기 용제인 디메틸 포름아마이드(D.M.F)가 다량 사용되어지고 있으나 환경문제등으로 수성 폴리우레탄 수지로의 대체가 진행되고 있다.Impregnating the existing solvent-type polyurethane resin composition and coating the resin composition on the upper surface to form a silver surface layer, and gave a touch and functionality similar to natural leather by polishing or embossing the surface of the silver surface layer. In the case of manufacturing synthetic leather using such a solvent-type resin, dimethyl formamide (D.M.F), which is an organic solvent, has been used in a large amount, but is being replaced with an aqueous polyurethane resin due to environmental problems.
그러나, 수성 폴리우레탄 수지의 가공은 용제형 폴리우레탄 수지와는 달리 응고수에서의 용제의 용출로 인한 응고가 이루어지지 않아 기존의 가공방법으로는 가공을 할 수가 없다. 현재 수성 폴리우레탄 수지의 가공에는 스웨드(SUEDE)조 인공피혁 가공(함침가공), 부직포 가공(함침가공), 건식 합성피혁의 가공, 폼 코팅(FOAM COATING)가공, 투습 방수 코팅가공등이 사용되어 지고 있는데 이러한 가공방법중 함침가공의 경우 용제형 폴리우레탄 수지의 응고방법을 이용할 수 없으므로 가열장치에서 열풍 또는 기타 열원에 의한 건조법을 주로 이용하고 있다.However, unlike the solvent-type polyurethane resin, the processing of the water-based polyurethane resin is not solidified due to the elution of the solvent in the coagulated water, and thus cannot be processed by the conventional processing method. Currently, the processing of water-based polyurethane resins includes suede artificial leather processing (impregnation processing), nonwoven fabric processing (impregnation processing), dry synthetic leather processing, foam coating processing, and moisture-permeable waterproof coating processing. In the case of impregnation processing, the solidification method of solvent-type polyurethane resin is not available, and the drying method by hot air or other heat source is mainly used in the heating device.
도 1은 수지가 가열되어지는 방향으로 편재된 개념도로서, 가열에 의한 건조방법을 사용할 경우 수분이 증발됨에 따라 응고 또는 경화가 진행되어 진것을 설명하고 있다. 도 1에서 도면부호 1은 수성 폴리우레탄이 부직포에 함침된 상태, 2와 2'는 부직포를 구성하는 원사, 3은 부직포의 표면, 4와 4'는 종래에 수성 폴리우레탄 고형분이 편재되어 있는 상태를 각각 나타내고 있다.1 is a conceptual diagram ubiquitous in the direction in which the resin is heated, and illustrates that the solidification or curing proceeds as the moisture evaporates when the drying method by heating is used. In FIG. 1, reference numeral 1 denotes a state in which an aqueous polyurethane is impregnated in a nonwoven fabric, 2 and 2 'are yarns constituting a nonwoven fabric, 3 is a surface of a nonwoven fabric, and 4 and 4' are conventionally in a state in which an aqueous polyurethane solid is ubiquitous. Are respectively shown.
도 1에 도시되어 있는 것과 같이 열방향으로의 수지의 편재(MIGRATION)가 발생되면, 편재현상에 의해 함침포의 표면 양 방향으로 수지 및 안료가 집중되어 함침포가 딱딱해지는 또 다른 문제점이 발생한다.As shown in FIG. 1, when the dispersion of resin in the thermal direction occurs, the resin and pigment are concentrated in both directions of the surface of the impregnated fabric due to the ubiquitous phenomenon. .
상기의 방법은 또한 섬유사 표면에 수지가 강하게 코팅이 되어 함침포가 더 딱딱해진다. 종래에는 이를 방지하기 위하여 감열 겔화제를 사용하였으나 조건에 따라 변색, 열화가 되는 경우가 있어 반드시 수세를 행하여야 하는 결점이 있다.The method also has a strong coating of resin on the fiber yarn surface, making the impregnated fabric harder. Conventionally, a thermal gelling agent is used to prevent this, but depending on the conditions, there is a case that discoloration and deterioration, which must be washed with water.
본 발명은 수성 폴리우레탄 수지를 이용한 부직포의 함침가공에 있어서 전기한 바와 같은 문제점을 해결한 것으로서 아크릴계 및 비닐계 수계 고분자, 실리콘계 계면활성제, 분산제를 이용하여 감열 결화제를 사용하지 않고 수지의 편재를 방지하며 동시에 충분한 부드러움을 얻는 인공피혁 제조방법을 제공하여 극세사를 포함한 모든 종류의 부직포 및 직, 편물등에 대한 함침가공에서 충분한 고형분 함량과 부드럼움을 얻을 수 있으며 공정도 단순화 시켜 생산량을 증대시키고 경제성이 높으면서도 수세등의 후처리가 필요없는 것이 특징이다.The present invention solves the problems described above in impregnation processing of nonwoven fabric using an aqueous polyurethane resin, and by using acrylic and vinyl based polymers, silicone surfactants, and dispersants, the ubiquity of resin is eliminated without using a thermal binder. Providing a method of manufacturing artificial leather which prevents and at the same time obtains sufficient softness, it is possible to obtain sufficient solids content and softness in impregnation processing of all kinds of nonwoven fabrics, including microfiber, and woven and knitted fabrics. It is high, but does not require post-treatment such as water washing.
