First of all, we need to add a concept, what is "leather" and what is "leather".
"Skin" refers to the original state of the animal's body, without adding any treatment. In contrast, "leather" refers to the physical and chemical treatment of animal skin to form an article.
By extension, leather is made from animal skins, and artificial leather is made of chemical fiber materials.
It should be known that the real leather mentioned in the market is generally one of the two kinds of first skin and two skins, plus synthetic skin, and the price of the three skins decreases in turn.
So, is cow leather real cow leather?
Please follow the article and read slowly.
Cow leather production accounts for 2/3 of the world's total leather production, of which 2/3 of the cow leather is used to make leather shoes, the rest is used for processing clothing bags and so on.
Leaving aside the use of leather origin and tanning technology to divide the grades, the cowhide itself is divided into multiple layers.
The outermost layer is the cephalic skin, followed by the second layer.
The first layer of the skin retains the granular layer of the natural cowhide epidermis, which has good elasticity and skin-friendly feeling. However, due to the first layer of leather products, it will be because of the defects of the cowhide itself and the elasticity of some skins, and the waste of materials is extremely serious. A whole piece of cowhide can sometimes only make a small finished product.
It is also for this reason that any item made of the first layer of cowhide is relatively high in price.
Relative to the cephalic skin, the second layer of the skin is inferior to the cephalic skin in terms of strength elasticity and breathability.
This is due to the loss of the epidermis of the second layer of the skin, which can only be covered with colloidal matter, with a membrane attached to simulate a texture close to the original epidermis. But even so, its touch and texture are still not able to catch up with the original scalp.
Of course, due to finishing, the second finished product can exceed the first layer of skin in terms of wear resistance, which is one of the reasons why the second layer of skin is popular.
In fact, "synthetic leather" is a certain sense of artificial leather, such as PU, PVC, etc., before there have been separate articles, here will not be repeated.
Speaking of which, we return to the question "Is cow leather real cow leather?" ”
That is, cow leather is not real cowhide in the true sense of the word.
This is why the price of items made of cow leather on the market will be lower than that of real head cowhide products.
So the cephalic skin as a dermis must be the best?
Unfortunately, this is not the case.
The first layer of the skin is also divided into many kinds, the skin surface is perfect without processing, with a natural granular texture, called full grain surface. This kind of scalp is the part of the legend that is good and expensive and scarce. Those who are big names or expensive, for this reason.
The second is that the skin surface with mild defects needs to be slightly treated, which is called half-grain surface. This type is relatively low in price, but the finished product is good in terms of cost performance.
Then there is the trim leather, its skin surface is seriously sweaty, it needs to be fully polished into a smooth surface, and finally coated and embossed, without a native texture. Common is lychee pattern.
Finally, regenerated skin, the worst dermis. As the name suggests, it is the waste skin of various animals is crushed and processed, the strength and quality are poor, and the smell of the leather is burned up, and the price is very low.
