1, recycled leather (also known as leather board), it is not really a traditional sense of paper, will be

Leatherwear

The waste leather of factories and tanneries can be treated by washing, returning to soft, grinding, adding adhesives, and so on, and is made of paperboard like materials.

2. Artificial leather is made of polychloroethane, polyurethane and other resins, and is made of cloth and woolen as raw materials. It is generally airtight. But with the progress of science and technology, the technology of artificial leather is becoming more and more mature, and the quality of products is greatly improved. Especially in the simulation of leather, it can be spurious and spurious, and its permeability, softness, handle and appearance are similar to natural leather.

So many foreign animal protection organizations advocate people wearing artificial leather clothing against the use of natural leather.

3, natural leather is the leather made of animal's skin after processing, grinding, softening and dyeing.

It's leather in the real sense.

The most expensive one is natural leather.

brand

The choice of taking.

Quite a lot

The leather series of big brands are luxury goods.

How can we distinguish them very well? The technology of artificial leather has been very clear now. When we buy leather products, we should make a careful distinction and not buy fake leather products that are not in accordance with the price.

Patterns, pores, and evenly distributed (like human skin are natural distribution), the lateral section of the layer is obvious, the lower layer has animal tissue fibers, scraping with the finger nail will appear the leather fibers are erected, there is a sense of raising, and a small amount of fiber can also fall down. The reverse side of the artificial leather can see the fabric, the side has no animal fibers, the surface has no pores, but some have imitation leather artificial pores, there will be no obvious pores exist, the patterns are not obvious, or there are regular artificial patterns, the pores are also quite consistent (very regular distribution); although the regenerated leather has animal fibers, but they are short, broken fibers, and the surface naturally has no natural patterns and pores. Visual discrimination method: from the leather pattern, pores and other aspects to distinguish, on the surface of natural leather can be seen.

Hand identification method: the leather feels elastic, and the leather fold will be 90 degrees or so. Natural wrinkles will appear. The thickness and thickness of the wrinkles will be different from each other. It is obvious that the skin is naturally dermis, because the dermis has a natural fibrous tissue structure.

Artificial ground and synthetic leather feel like plastic, with poor recovery and similar thickness and thickness of the fold.

Odor identification: natural leather has a very strong fur taste, even after passing the foliage, the taste is more obvious; and synthetic leather, synthetic leather products, there is a plastic taste, no fur taste.

Take a small sample to burn, mainly to smell the smell and look at the ashes.

Natural leather burns when it burns. It burns a fragile powder, while artificial leather, synthetic leather and regenerated leather burn more vigorously, shrink rapidly, and have a very smelly smell of plastic, which is sticky after burning, and will harden into lumps after cooling.

Of course, when you buy clothes, you can't burn it! It's mainly about the feel and surface texture.

Finally, there is a recipe, freezing heating test: natural leather generally does not change with the ambient temperature.

Artificial leather and synthetic leather are hard to fry at the refrigerator temperature, and appear soft when the light is roasting.

This is more difficult for ordinary consumers to operate.
