The identification method of true and false leather mainly has drip test, which is used to meet the obvious natural leather with strong water absorption. On the contrary, it is artificial leather. Another method is elasticity and tension test. Natural leather actually has very good tension and elasticity. On the contrary, it is artificial leather. The air blowing test is mainly to blow saliva on the reverse side of the quasi leather. If there is penetration on the front side, the cold proof effect will be very obvious and form a very good air permeability after wearing leather clothes because the leather has anti reverse performance, which mainly reflects the value of leather. In terms of visual identification, first, we should constantly identify the patterns and pores of leather. From the surface of natural leather, the patterns and pores do exist, but the distribution is relatively uneven. On the reverse side, there are animal fibers and side sections, which are more obvious and recognizable on the level. There will be animal fibers in the lower layer, and the leather fibers will stand up when we try to scrape with our fingernails, It also feels fluffy. A small amount of fiber will also fall down, but the fabric can be seen on the reverse side of synthetic leather. Therefore, there is no animal fiber on the side. Generally, there are no pores on the skin. However, some imitation leather artificial pores also have insignificant pores. Some patterns are relatively not obvious, while some artificial patterns are relatively regular and the pores are relatively consistent.
The advantages of processed leather are wear-resistant, beautiful and washable. After polishing the surface, the frosted leather can wear away the scar grain surface or rough fibers, and show the relatively neat fiber leather tissue. After dyeing, it can be dyed into many popular colors. Reverse velvet skin is a kind of head skin made by grinding the leather on the surface of leather embryo into velvet shape, dyeing it, and dyeing various popular colors. Fiber leather is mainly characterized by outstanding texture. For fiber leather, which is famous for its elegant appearance, it is the best representative of luxury and noble spirit.
