Como identificar couro genuíno ou couro falso?
Nas compras diárias, comprar sapatos femininos tornou-se o comportamento de consumo mais comum das pessoas. Contudo, no mercado interno, a qualidade dos sapatos é desigual. Ao escolher os sapatos, muitas pessoas se preocupam se os sapatos que compram pertencem ao couro genuíno? Especially when buying large-brand women’s shoes, porque o preço é relativamente alto, precisamos distinguir entre couro genuíno e sapatos de couro falso. Então, que tipo de couro é considerado couro genuíno? Se sapatos de couro devem ser bons, let’s solve the identification of leather materials with these questions!
First of all, we touch the surface of the leather with our hands. Generally, the leather will feel smooth, soft, plump and elastic. And synthetic leather, its hand feel is hard, a bit like plastic, and the resilience is poor when you press it with your hand, and when you bend it with your hand, the thickness of the concave folds does not change much.
Second, general natural leather, because it is a pure natural biological leather layer, will have a strong fur smell, even after processing, the smell is more obvious, but artificial leather products, because they are made by purification workers, have Smells like plastic, no fur.
Third, the surface layer of natural leather will have some finer pores, which are small and irregular, evenly and tightly distributed, and the surface looks plump in texture, and burning with a lighter will have a burning smell of meat.
But whether the leather is necessarily good, in fact it is not, the leather also has the first layer of skin and the second layer of skin, which is also the difference between the quality of the leather, so how should we distinguish it?
Top layer skin: Generally, it is directly processed from the original cow hide, or the cowhide is cut into two upper and lower layers after dehairing. The head skin is composed of a dense and thin fiber layer and a slightly loose transition layer that is closely connected with it, and has the characteristics of good strength, elasticity and process plasticity.
Two-layer skin: Generally, it is the two-layer part with loose fibrous tissue, which is processed by spraying chemical materials or covered with PVC and PU films. The second-layer skin has a loose fibrous tissue layer, which can only be used to make leather products after spraying chemical raw materials or polishing. It maintains certain natural elasticity and process plasticity characteristics, and its thickness is the same as that of the first-layer skin.
