The present invention relates to a method for producing high durability and heat resistant leather. More specifically, by applying the hollow microsphere microcapsules together with the coating material during the base coating in the coating process of natural leather, it blocks heat transfer from the outside and maintains heat retention. It improves the resistance to abrasion due to impact, and relates to a manufacturing method of high durability and heat-resistant leather to improve the resistance to moisture by additional coating of a water repellent during top coating.
가죽소재는 독특한 색상과 질감, 그리고 고급스러움 때문에 가방, 신발, 의류, 악세서리와 같은 생활용품뿐만 아니라, 자동차, 비행기, 선박용 내장재, 가구, 실(Seal)용 패킹 등 산업 전반에 다양하게 사용되고 있다. Because of its unique color, texture, and luxury, leather materials are used in a variety of industries such as bags, shoes, clothing, and accessories, as well as automobiles, airplanes, ship interiors, furniture, and seals.
최근 동계스포츠에 대한 소비자의 관심이 증대됨에 따라 기능성에 대한 요구가 증대되고 있으며, 방한화, 스노우보드화, 스키부츠 등 가죽소재가 사용되는 분야에 보온성, 고내구성, 방발수성 등과 같은 특성이 요구되고 있으나, 소비자의 기대에 부응하지 못해 기능성 섬유 제품으로 대체되고 있는 상황이다. Recently, as consumers' interest in winter sports has increased, the demand for functionality has increased, and properties such as warmth, high durability, and water repellency are required in areas where leather materials such as winter shoes, snowboard shoes, and ski boots are used. As a result, they are being replaced by functional fiber products because they do not meet consumer expectations.

If the amount is more than 50%, the adhesion of the functional material to the leather surface is lowered and the surface is reduced. This is rough and there is a problem that the manufacturing cost rises.
베이스 도장공정(S110)에서 중공미세구 마이크로캡슐은 염화비닐 수지, 초산 비닐수지, 폴리스틸렌 수지, 폴리에틸렌 수지, 폴리아미드 수지, 및 메타아크릴 수지를 포함하는 열가소성 수지와 포타슘 실리케이트, 소듐 실리케이트, 리튬 실리케이트로 이루어진 군으로부터 선택한 1종 또는 그 이상을 선택하여 사용하는 것이 바람직하다.In the base coating process (S110), the hollow microsphere microcapsules include thermoplastic resins including vinyl chloride resin, vinyl acetate resin, polystyrene resin, polyethylene resin, polyamide resin, and methacrylic resin, potassium silicate, sodium silicate, and lithium silicate.
