The significance of cowhide in fortune telling _ What is the significance of cowhide in fortune telling?

What does all blue cowhide mean? How is the thickened cowhide thickened?

All-green cowhide (that is, all-green cowhide) is the most commonly used leather material in leather sofas, which comes from buffalo and cattle.

All-green leather (all-green leather) is full-grain upper leather, which is made of top-grade raw leather, with little damage and the leather surface remains intact and natural. Thin coating can show the beauty of natural patterns of leather, wear resistance and good air permeability; All-green leather is dyed directly with blue warm leather, which rejects too many chemicals, so tiny pores can be clearly seen on the leather surface, which is realistic and breathable. The price is the most expensive among leather types, but the price is not the complicated tanning process and a lot of chemical materials, but the thick leather quality.

The whole green leather is different from ordinary leather: in the selection of leather embryo, it is necessary to choose captive and castrated bull cowhide, because the fiber tissue of bull cowhide is dense and wide. The most important thing is to keep it in captivity, which makes its skin less scarred, which is the best choice for making high-grade leather. Secondly, in manufacturing, it makes its overall effect more noble and elegant.

Defects of full green leather: Because it is genuine leather, it is the easiest to absorb things on its surface. If it is often rubbed with water or used with poor cleaning and maintenance products, it is most easily absorbed into leather, thus wrinkling, hardening, cracking and peeling. So the whole green skin must be well maintained.

There are two main ways to thicken leather:

One is to cover the second skin with a thick chemical film, and the second skin under the film is very thin. Then consumers will see a thick layer of chemical materials from the anatomical surface of leather, which will aggravate the plastic feeling of the fabric and lead to no one buying it. This method is rarely used now.

Second, the second layer of leather is covered with a thin chemical film, so that consumers can't see a layer of chemicals from the anatomical surface of leather. Then, the second skin like fat must be thick, otherwise, the second skin composed of thin chemicals and thin fat will break at once.

Please note here that many consumers have a misunderstanding in their consumption: they reject soft, light and durable high-priced one-layer leather and prefer thick and durable cheap two-layer leather, thinking that thick skin is good skin. In fact, this thickness is limited to the category of cheap double skin. When you have seen the technological principle of two-layer leather, you will understand that of these two kinds of two-layer leather, it is of course thick and durable.

So what are the first dermis and the second dermis in leather? Composite dermis, taking the famous pigskin as an example;

The skin on the surface of pigskin is the first dermal layer; Cut the white fat like fat under the pigskin, dry it, and then cover it with a chemical film to form two layers of dermis.

Cowhide can be cut into 16 layers. Therefore, two-layer leather is a general term for 2- 16-layer leather.

Composite dermis is the skin formed by mashing, drying, bonding together with chemical materials, and covering those things that can no longer be cut with chemical films.
