Description
본 발명은 재생가죽에 관한 것으로서, 더욱 상세하게는 가죽 질감을 구현함은 물론 가죽이 부드럽고 시트의 적층(積層) 간에 결합력이 우수한 재생가죽에 관한 것이다.The present invention relates to regenerated leather, and more particularly, to regenerated leather that not only realizes a leather texture, but also has soft leather and excellent bonding strength between stacks of sheets.
일반적으로 천연가죽은 동물의 몸을 감싸고 있는 질긴 껍질로 뛰어난 물성으로 인해 가방, 가구 등 다양한 분야에서 널리 사용되고 있다. 천연가죽은 동물의 몸으로부터 분리된 후 화학적, 물리적인 가공과정을 통해 제품으로 제조되는데, 여러 단계의 가공과정 중 원하는 제품의 디자인에 맞게 재단하는 공정은 필수이다. 그런데 재단공정을 거치면서 다량의 가죽 폐기물이 발생되며, 가죽 폐기물의 대부분은 소각 및 매립으로 처리되어 이로 인한 환경적인 문제가 심각하게 대두되고 있는 실정이다.In general, natural leather is a tough skin covering an animal's body and is widely used in various fields such as bags and furniture due to its excellent physical properties. After the natural leather is separated from the animal's body, it is manufactured into a product through chemical and physical processing. Among the various stages of processing, it is essential to cut it to fit the design of the desired product. However, a large amount of leather waste is generated during the cutting process, and most of the leather waste is treated by incineration and landfill, thereby seriously raising environmental problems.
한편, 천연가죽을 가공할 때 발생하는 가죽 폐기물뿐만 아니라 인조가죽 등의 피혁이나 각종 섬유 등을 가공할 때 발생하는 폐기물 및 이들을 사용하고 남은 스크랩 등은 다양한 분야에서 활용하고 있으나 그 적용범위가 매우 한정적일 뿐만 아니라 피혁 폐기물이나 스크랩은 대부분 매립하거나 소각하는 방법으로 처리하기 때문에 환경문제로 심각하게 대두되고 있다.On the other hand, not only leather waste generated when processing natural leather, but also waste generated when processing leather such as artificial leather or various fibers, and scraps remaining after using them are utilized in various fields, but the scope of application is very limited. In addition to work, leather waste and scrap are mostly treated by landfill or incineration, which is a serious environmental problem.
이와 같이 천연가죽이나 인조가죽, 섬유 등의 폐기물 및 스크랩이 환경문제를 유발시키는 가장 큰 이유는 재활용률 저하로 인해서 소각, 매립 등의 방법으로 폐기물과 스크랩일 재자원화하지 못하는 것이 주원인으로 주목되고 있다.As such, the biggest reason that wastes and scraps such as natural leather, artificial leather, and textiles cause environmental problems is the inability to recycle waste and scrap through methods such as incineration and landfill due to a decrease in the recycling rate.
따라서, 본 발명자는 위와 같은 피혁 또는 섬유 폐기물이나 스크랩을 재활용하여 환경오염을 최소화하는 방안으로 재생가죽을 개발하게 되었다.Therefore, the present inventors have developed a recycled leather as a method of minimizing environmental pollution by recycling the leather or textile waste or scrap as described above.
본 발명은 가죽 질감을 구현함은 물론 가죽이 부드럽고 시트의 적층 간에 결합력이 우수한 재생가죽을 제공하는데 그 목적이 있다.An object of the present invention is to provide a regenerated leather that not only realizes the texture of leather, but also has soft leather and excellent bonding strength between laminations of sheets.
본 발명의 다른 목적은 재생가죽을 제조할 때 극세사(장섬유)를 혼합함으로써 재생가죽의 인장강도 및 인열강도를 향상시킨 재생가죽을 제공함에 있다.Another object of the present invention is to provide a regenerated leather having improved tensile strength and tearing strength of regenerated leather by mixing microfibers (long fibers) when manufacturing regenerated leather.

본 발명에 따른 재생가죽은 천연가죽이나 인조가죽 등의 피혁 폐기물 또는 스크랩, 각종 섬유 폐기물이나 스크랩을 사용하여 재생가죽을 제조함으로써 환경오염을 최소화할 수 있을 뿐만 아니라 가죽 질감을 구현하면서 가죽이 부드럽고 시트의 적층(積層) 간에도 결합력이 우수하여 신발, 가방, 가구 등의 다양한 제품에 사용할 수 있다. 또한, 본 발명은 재생가죽을 제조할 때 섬유원단에 극세사(장섬유)를 10~50% 혼합하여 사용함으로써 인장강도 및 인열강도가 향상된 재생가죽을 구현할 수 있다.The regenerated leather according to the present invention can minimize environmental pollution by manufacturing regenerated leather using leather wastes or scraps such as natural leather or artificial leather, and various textile wastes or scraps, while realizing the leather texture, and the leather is soft and the seat It can be used for various products such as shoes, bags, furniture, etc. because of its excellent bonding strength even between the layers of laminates. In addition, the present invention can implement regenerated leather with improved tensile strength and tear strength by mixing 10 to 50% of microfibers (long fibers) with the fiber fabric when manufacturing regenerated leather.
