Artificial leather is classified according to the layers of leather!

    According to the hierarchy of leather, there are two types of leather: top layer leather and second layer leather. The top layer leather includes grain leather, trimmed leather, embossed leather, special effect leather, and embossed leather; Second layer leather is divided into pig second layer and cow second layer leather, etc.
    Grain leather: Among many leather varieties, full grain leather ranks first because it is processed from high-quality raw materials with less damage. The leather surface retains its natural state intact, and the coating is thin, which can show the natural pattern beauty of animal skin. It is not only wear-resistant, but also has good breathability. The Tianhu series leather goods are made from this type of leather as raw material to produce high-quality leather products.
    Shaved leather: It is made by using a grinding machine to lightly coat the surface and then pressing the corresponding patterns onto it. In fact, it is a cosmetic surgery performed on natural leather surfaces with disabilities or roughness.

    Second layer leather: is made by slicing thick leather with a leather cutting machine. The first layer is used to make full grain leather or finished leather, and the second layer is made into second layer leather through a series of processes such as coating or film sticking. Its fastness and wear resistance are poor, making it the cheapest type of leather in the same category.
    The synthetic leather industry chain has formed thousands of upstream raw materials and tens of thousands of downstream manufacturers. Synthetic leather not only belongs to the plastic industry, but also is distributed in leather systems, textile systems, military, transportation and other systems. In addition, the production and manufacturing of synthetic leather is a highly specialized field, involving the application of dozens of plastic polymer materials, inorganic filling media, different types of Textile Fabric theories, intelligent automation applications, printing, coating industry, clothing industry, footwear industry and other cultural theories; The design of product patterns should apply cultural knowledge related to aesthetics, philology, plants, animals, nature, geometry, and so on.
