One is that commodity is made of genuine leather quality must be good. Leather is for people to natural leather leather and difference between the habits epithet. By mammal leather, leather processing becomes very much, quality and type, such as the cow leather of cattle leather, buffalo and points PianNiu yak leather and leather, leather, sheep leather into sheep leather and goat leather. Moreover leather have different levels are generally divided into three layers, domestic technical XianJinZhe can be divided into 8 layer, leather goods generally USES the first layer and 2 leather, including: first layer, and not only wear leather with good air permeability, and 2 leather fastness and wearability are poor, so different commodities should choose appropriate leather, cannot think leather goods quality must be good. 2 it is think commodity is made of genuine leather is 100% genuine leather. Now in the market a lot of so-called “dermal” commodity, will use part of leather and partial imitation leather together do, in some obvious, main position with leather and some covert, secondary position with imitation leather with low cost of commodity, which on the second floor, or on the leather with imitation leather add layer coated to replace the dermis, such permeability is greatly reduced.
