本革または合成皮革を識別する方法?
毎日の買い物で, 女性の靴を買うことは人々の最も一般的な消費行動となっている. でも, 国内市場で, 靴の品質が不均一. 靴を選ぶとき, 多くの人が購入する靴が本革のものかどうか心配しています? Especially when buying large-brand women’s shoes, 価格が比較的高いので, 本革と合成皮革の靴を区別する必要があります. では、どのような革が本革と見なされますか? 革靴が良いに違いないか, 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.
