Background

The shoe upper is processed in a plurality of ways and is made of various materials, the shoe upper is mostly made of PVC and PU, the uppermost layer of the PVC is paint, the middle main component is polyvinyl chloride, the lowermost layer is back-coated with adhesive, and the PU is commonly called synthetic leather and has light specific gravity. PU grains are paper grains, namely PU pulp is coated on release paper with the grains, and the paper is peeled after cooling and shaping, so that the paper grains are left on the PU layer. PU can also be subjected to post-processing embossing, and the production process includes a wet method and a dry method. The two are very easy to distinguish. Wet method is generally thicker, because a layer of BASE (low foaming layer) is arranged between the surface layer and the BASE cloth, and dry method has no BASE and is directly coated on the cloth bottom, the wet method has thinner and more deformable lines, the wet method PU has wider application range, not only can be used for shoe production, but also can be used for bags, handbags, balls, stationery, sofas and the like, and the dry method is mainly used for packaging and clothing.
