Description

가죽 원단에 무늬를 인쇄 하는 방법과 이에 의해 인쇄된 가죽원단{PRINTING METHOD FOR LEATHER AND THE PRINTED LEATHER THEREOF}PRINTING METHOD FOR LEATHER AND THE PRINTED LEATHER THEREOF

본 발명은 가죽 표면에 각종 무늬를 인쇄하여 여러 용도로 사용하기 위한 가죽 원단에 각종 무늬를 인쇄하기 위한 방법과 이에 의해 인쇄된 가죽원단에 관한 것이다.The present invention relates to a method for printing various patterns on a leather fabric for use in various applications by printing various patterns on the leather surface and the leather fabric printed thereby.

가죽은 그 사용 용도가 다양하여 널리 상용되고 있다.Leather is widely used due to its various uses.

이러한 가죽 제품은 가죽 원단에 염색하는 방법에 의하여 색상을 투여하고 있으므로 그 무늬가 다양하지 못한 단점이 있다.These leather products have a disadvantage that the pattern is not varied because the color is administered by dyeing the leather fabric.

이러한 단점을 극복하기 위하여 근래에 가죽 원단 자체에 무늬를 인쇄하는 방법이 제공되고 있는데, 그중에서 대한민국 공개특허 1999-0045903호가 있다.In order to overcome such disadvantages, a method of printing a pattern on a leather fabric itself has recently been provided, among which there is a Korean Patent Publication No. 1999-0045903.

이는 폴리우레탄 수지, 경화제 및 증점제를 사용한 조성 잉크를 가죽 원단의 표면에 스크린 인쇄하는 방법에 의하여 인쇄를 행하고 있다.This is printed by the method of screen-printing the composition ink using a polyurethane resin, a hardening | curing agent, and a thickener on the surface of leather fabric.

그러나 이러한 인쇄 방법은 광택 및 입체감이 두드러지는 장점은 있으나 폴리우레탄 수지를 바인더로 사용하기 때문에 인쇄공정시에 고온으로 경화되는 과정에서 가죽이 신축 변형되는 문제점이 있기 때문에 반드시 상온 경화를 위하여 경화제를 사용해야 하는 문제점이 있다.However, this printing method has the advantage that gloss and three-dimensional appearance are outstanding, but since the polyurethane resin is used as a binder, there is a problem that the leather is stretched and deformed during curing at high temperature in the printing process, so a curing agent must be used for room temperature curing. There is a problem.

또한 경화제의 사용에 의하여 상온 경화는 가능하나 장시간 건조 과정을 거쳐야 하는 문제점으로 인해 생산성이 떨어지는 문제점도 있다.In addition, the room temperature curing is possible by the use of a curing agent, but there is also a problem in that productivity is lowered due to a problem of undergoing a long drying process.

그리고 대한민국 공개특허 2000-0024411호의 경우에는 고무판 및 가죽 표면에 도료를 도포시킨 다음, 전사지를 피복하여 히팅프레스로 가열 가압시키는 방법을 이용하여 가죽을 인쇄하는 방법을 제공하고 있다.In the case of Korean Patent Laid-Open Publication No. 2000-0024411, there is provided a method of printing leather using a method of coating a transfer sheet on a rubber plate and a leather surface, and then applying a heat press to a transfer paper.

그러나 이러한 경우에는 히팅프레스로 가열 가압하여 전사지의 무늬를 열전사시킬때에 전사지가 열에 의하여 고무판 또는 가죽 표면에 눌러 붙어 전사지가 떨어지지 않고, 떨어져서 무늬를 가죽 표면에 열전사시켰다 하더라도 황변현상이 발생하는 문제점이 있다.However, in this case, when the transfer paper is heat-transferd by heating press to heat transfer, the transfer paper is pressed to the rubber plate or the leather surface by heat, so that the transfer paper does not fall off, and yellowing phenomenon occurs even if the transfer is heat-transferred onto the leather surface. There is this.

그리고 대한민국 특허등록제 221666호가 있는데 이는 2∼5도의 채도를 가지도록 염료를 가죽에 침투시키는 방법에 의하여 가죽에 인쇄하는 방법을 제공하는 것이다.In addition, there is Korean Patent Registration No. 221666, which provides a method of printing on leather by penetrating dye into leather so as to have a saturation of 2 to 5 degrees.

이는 수성염료층을 가진 1차 반가공물을 제조한 다음에 우레탄계 접착제를 사용한 다음 건조한 후에 다시 수성광택제를 사용하여 2차 반가공물을 제조한 다음, 핫 프레스(hot-press)를 이용하여 다림질하는 가공를 행한 다음에 로울러 인쇄기로 염료를 가죽 표면에 투여하는 방법을 통해 임의의 얼룩무늬를 인쇄하는 것이다.It is a process of preparing a primary semifinished product having an aqueous dye layer, using a urethane-based adhesive, drying, and then preparing a secondary semifinished product using an aqueous varnish, and then ironing it using a hot press. After this is done, any stain is printed by a method of administering the dye to the leather surface using a roller printing machine.

그러나 이는 제조 공정이 너무 복잡한 단점이 있다.However, this has the disadvantage that the manufacturing process is too complicated.

특히 그중에서도 염료를 투여하기 위한 과정에서 로울러인쇄기를 이용하는데 그 로울러의 표면에 원하는 무늬만을 음각하여야 하므로 생산 제품이 다양한 무늬를 연출할 수 없는 단점, 에컨데 로울러에 음각된 무늬 이외의 다른 무늬를 연출하기 위해서는 별도의 무늬를 다시 로울러의 표면에 음각하여 사용하여야 하므로 생산에 많은 비용이 충당될 뿐만 아니라 구매자의 욕구에 대처하기가 어려운 문제점이 있다.In particular, the roller printing machine is used in the process of dispensing dyes, and since only the desired pattern is engraved on the surface of the roller, the produced product cannot produce various patterns, for example, to produce a pattern other than the engraved pattern on the roller. In order to use a separate pattern is engraved on the surface of the roller back to use a lot of costs in production, there is a problem that it is difficult to cope with the buyer's desire.

이러한 문제점을 감안하여 본 출원인이 2001년 특허출원 제29083호를 출원한 바 있는데 이는 열 전사를 행하여도 전사지가 가죽의 표면에서 쉽게 분리되도록 하고, 또한 열전사된 제품의 색상이 가죽표면에서 그대로 유지할 수 있도록 할 수 있도록 한 것이다.In view of this problem, the applicant filed a patent application No. 29083 in 2001, which allows the transfer paper to be easily separated from the surface of the leather even after thermal transfer, and also maintains the color of the thermally transferred product on the surface of the leather. It is to be able to.

그런데 시간이 지나면 지날수록 열전사한 자외선에 의하여 서서히 발하는 문제점이 있었다.However, as time passes, there was a problem of slowly releasing due to thermal transfer ultraviolet rays.

본 발명은 이러한 문제점을 해결하기 위하여 창출된 것으로 통상적으로 이용되어온 열전사 방법에 의하여 가죽 표면에 각종 색상을 가진 무늬를 인쇄하고, 그 인쇄면이 태양의 자외선이 의하여도 쉽게 발하는 문제점을 해결하고자 하는데 있다.The present invention was created to solve this problem is to print a pattern having a variety of colors on the surface of the leather by a thermal transfer method that has been commonly used, and to solve the problem that the printing surface is easily emitted even by ultraviolet rays of the sun. have.

이러한 본 발명에서는 비록 가죽의 표면에 상용되어온 열 전사를 행하여도 열전사된 무늬 색상이 가죽표면에서 발하지 않고 또한 무늬가 위부에서는 돌출되는양각적 시각을 나타내도록 하기 위하여 본 발명에서는 가죽에 전시된 무늬를 폴리 우레탄 수지 또는 폴리 에스테르 수지층을 피복하여 무늬의 색상을 보호하고, 또한가죽에 표현된 전사 무늬와 동일한 무늬 또는 돌출되는 그 어떠한 둘출부를 형성한폴리 우레탄 수지 또는 폴리 에스테르 수지층이 가죽에 표현된 무늬의 상단에 위치하도록한 가죽을 제공하여 무늬 색상 보호 및 무늬의 3차원적 시각 효과를 얻을 수 있었다.In the present invention, even if the heat transfer that has been commonly used on the surface of the leather, the heat transfer pattern color does not appear on the leather surface and the pattern displayed on the leather in the present invention in order to display an embossed view of the pattern protruding from the upper portion The polyurethane resin or polyester resin layer is formed on the leather to protect the color of the pattern by covering the polyurethane resin or polyester resin layer, and also to form the same pattern or any protruding portion protruding from the transfer pattern represented on the leather. By providing the leather on the top of the textured pattern, the pattern color protection and the three-dimensional visual effect of the pattern were obtained.
