How to distinguish between natural leather, artificial leather and recycled leather

1. Recycled leather (also known as leatherboard paper), which is not really a paper in the traditional sense. It is used to treat leather and tannery waste leather by washing, softening, grinding, adding adhesives, etc. It is similar to cardboard material, so the name is leather paper, which can be used as material for tanning, box making and so on.

2, artificial leather is made of polyvinyl chloride, polyurethane and other resins as coatings, cloth and woolen cloth as the base material, generally not air-permeable, but with the advancement of science and technology, artificial leather technology is also becoming more mature, product quality is greatly improved, Especially in the case of artificial leather, it can be faked, and its breathability, softness, hand and appearance are similar to natural leather. Therefore, many foreign animal protection organizations advocate people wearing artificial leather clothing against the use of natural leather.

3, natural leather is the leather of the animal's skin after processing, grinding, softening, dyeing. It is leather in the true sense. The most expensive is natural leather, which is the choice of many brands. Many international brands of leather are luxury items.

So how can we distinguish them very well? The artificial leather craftsmanship is very good now. We must carefully distinguish the leather products when buying them. Don’t buy fake leather products that are not worth the price (unless you buy artificial leather yourself) .

Visual identification method: It is distinguished from the pattern of leather, pores, etc. The pattern and pores can be seen on the surface of natural leather, and the distribution is even (like the natural distribution of human skin), the side profile is obvious, and the lower layer has Animal tissue fibers, scratched with fingernails will appear leather fibers up, have a feeling of napping, a small amount of fiber can also fall; artificial leather can see the fabric on the reverse side, no animal fibers on the side, no pores on the surface, but some have imitation Artificial pores of the skin, there will be inconspicuous pores, the pattern is not obvious, or there are more regular artificial patterns, the pores are also quite consistent (very regular distribution); although the recycled leather has animal fibers, they are all shorter The broken fiber is pressed, and the surface naturally has no natural patterns and pores.

Hand-feeling method: The leather feels elastic. When the leather is folded down by 90 degrees, natural wrinkles will appear. The different parts will be bent, and the thickness of the pleats will be different. There is obvious unevenness. It can be considered that this is leather. Because the dermis has a natural fibrous structure. The artificial ground and synthetic leather feel like plastic, and the recovery is poor. The thickness and the pleats of the bends are similar.

Odour identification method: Natural leather has a very strong fur smell, even if it is processed, the taste is more obvious; while artificial leather and synthetic leather products have the taste of plastic and no fur. Take a little sample and use a fire to burn, mainly to smell the smell and look at the ashes. When the natural leather burns, it will emit a scorching smell of hair, and the burnt one will be broken into powder. The artificial leather, synthetic leather and recycled leather will have a strong flame when burning, shrink quickly, and have a bad smell. Plastic taste, sticky after burning, will become hard and become blocky after cooling. Of course, when you buy clothes, you can't let you burn! It depends mainly on the feel and surface texture.

Finally, there is a remedy, freezing - heating test method: natural leather generally does not change with the ambient temperature and soft and hard. Artificial leather and synthetic leather are hard to feel at the freezing temperature of the refrigerator, and appear soft under the light baking. This is more difficult for ordinary consumers to operate.

A gear or cogwheel (Gear Wheel) is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation.
