인공 피혁이라 함은, 화학섬유 소재를 이용하여 외관 및 성상에 있어서 천연피혁과 흡사하게 만든 것으로, 혼합방사 또는 복합 방사 방법에 의해 제조되는 분할형 또는 해도형의 복합섬유 극세사 또는 일반 극세사를 그 기본 소재로 이용하여 인위적으로 제조되며 현재 일본 및 한국에서 주로 개발되고 상품화되고 있는 최첨단 화학소재이고 부직포를 기포로 하여 주로 폴리에틸렌 수지를 습식 함침 또는 코팅 가공한 소재로서 그 주된 구조와 기능성, 유연성 면에서 천연피혁과 유사하고 오히려 내세탁성 불량, 불안정성, 항균 방취성 불량, 염색견뢰도 저하 등의 천연피혁의 결점을 보완하는 우수한 장점을 갖고 있어 천연피혁의 대체소재로서 각광을 받고 있다.Artificial leather is made of chemical fiber material, which is similar to natural leather in appearance and appearance, and is based on split or island-in-the-sea composite fiber microfiber or general microfiber manufactured by mixed spinning or composite spinning method. It is a state-of-the-art chemical material that is artificially manufactured using materials and is currently developed and commercialized mainly in Japan and Korea.It is a material that is mainly impregnated with wet or impregnated polyethylene resins with non-woven fabric as its main structure, functionality, and flexibility. It is similar to leather, but it has the outstanding advantage of compensating for the shortcomings of natural leather, such as poor washing resistance, instability, antibacterial deodorization, and low color fastness.
일반적으로, 피복류, 신발, 모자, 커튼, 봉제 완구 등과 같이 인공 피혁을 이용하는 제품은, 그 제품의 특성 및 디자인을 감안하여, 염색, 재단, 봉제 등의 공정을 거치게 되고 여기에 제품의 특징을 살릴 수 있는 다양한 장식을 하게 된다.In general, products using artificial leather, such as clothing, shoes, hats, curtains, stuffed toys, etc. are subjected to processes such as dyeing, cutting, sewing, etc. in consideration of the characteristics and design of the product, and to utilize the characteristics of the product. Various decorations can be made.
그러나, 종래의 제품은 색상 및 디자인을 창출하는데 있어, 대다수가 염색에만 의존함으로써, 색상 개발에 한계를 가지게 되고, 제품의 다변화를 꾀하기 어려운 문제가 있다.However, in the conventional products to create colors and designs, the majority of them rely on dyeing, there is a limit in the color development, there is a problem that it is difficult to diversify the product.
따라서, 근래에는 인공 피혁의 디자인을 창출하기 위하여, 인공 피혁의 표면 에 스티커를 이용하여 도형, 그림, 문자 등을 그려 넣는 방법, 자수를 놓는 법, 금속 박막을 입히는 법 등이 개발되고 있다. 특히, 금속 박막을 입히는 방법은, 금속 박막의 반사성을 이용하여 독특한 미감을 형성할 수 있어, 피복, 신발 등을 중심으로 그 사용이 확대되고 있다.Therefore, in recent years, in order to create a design of artificial leather, a method of drawing a figure, a picture, a character, etc. using a sticker on the surface of the artificial leather, a method of embroidering, a method of coating a metal thin film has been developed. In particular, the method of coating a metal thin film can form a unique aesthetic using the reflectivity of the metal thin film, and its use has been expanded mainly on coatings, shoes, and the like.
그러나, 전술한 금속 박막은 일반적으로 사용되는 접착제와의 접착력이 낮아, 접착제를 이용하여 장신구를 덧붙이거나 다른 원단과 합포하기가 어렵다는 문제점이 있다.However, the above-described metal thin film has a low adhesive strength with a commonly used adhesive, there is a problem that it is difficult to add jewelry or combine with other fabric using the adhesive.
따라서, 이러한 문제점을 해결함으로써, 인공 피혁 제품의 디자인 창출을 보다 쉽게 할 수 있는 인공 피혁의 제조방법의 개발이 필요하다.Therefore, by solving these problems, it is necessary to develop a manufacturing method of artificial leather that can more easily create the design of artificial leather products.

상기 폴리우레탄 용액의 조성비는, 바람직하기로는 폴리우레탄 100 중량부에 유기 용제 50 내지 250 중량부 및 안료 0.1 내지 30 중량부가 되도록 하는 것이 좋으며, 함침용 폴리우레탄으로는 수평균 분자량 50,000 내지 200,000의 것이 적당하다.The composition ratio of the polyurethane solution is preferably such that 50 to 250 parts by weight of an organic solvent and 0.1 to 30 parts by weight of a pigment are used in 100 parts by weight of polyurethane, and the impregnated polyurethane has a number average molecular weight of 50,000 to 200,000. It is suitable.
상기 부직포 내부에 배합액이 침투하면, 폴리우레탄의 비용제계나 비용제 및 비용제혼합계에서 폴리우레탄을 응고시킨다. 그리고 50 내지 70℃의 열수에서 수세한 후 가충진된 수용성 고분자를 완전히 제거하고 나서 건조하면 폴리우레탄 탄성체가 갖는 특유의 유연한 탄성, 치밀감등이 발현되어 천연피혁과 같은 충진감이 부여된다.When the compound solution penetrates into the nonwoven fabric, the polyurethane is solidified in the non-system of polyurethane, the non-system and the mixture of non-agent. After washing with hot water at 50 to 70 ° C., the water-soluble polymer filled therein is completely removed and then dried to give a unique elasticity, denseness, and the like, which gives the elasticity of natural leather.
다음으로, 상기 함침된 부직포의 표면에 폴리우레탄 배합액을 도포하여 은층을 형성한다. 보다 구체적으로는, 폴리우레탄 배합액을 도포한 다음 응고조에 침지시켜 고체상의 은층을 생성시키고 잔여용제를 수세한 후 건조시킨다. Next, a polyurethane compound is applied to the surface of the impregnated nonwoven fabric to form a silver layer. More specifically, the polyurethane mixture is applied and then immersed in a coagulation bath to produce a solid silver layer, washed with residual solvent and dried.
상기 단계에서 폴리우레탄 배합액의 도포량은 1000~1500g/m2가 적당하고, 습식 은층용 폴리우레탄 조성액은 평균분자량 50,000~100,000인 폴리우레탄 수지(고 형분 30%) 100중량부에 대해 폴리올과 실리콘유로된 계면활성제 2 중량부, 지방산변성 계면활성제 1중량부, 디메틸포름아미드 200~300 중량부, 안료 5 내지 20 중량부로 배합하는 것이 바람직하다.In the above step, the coating amount of the polyurethane compound is suitably 1000 to 1500 g / m 2 , and the polyurethane composition solution for the wet silver layer is polyol and silicone based on 100 parts by weight of a polyurethane resin (30% solids) having an average molecular weight of 50,000 to 100,000.
