Material state of leather in use

Leather generally has a certain elasticity, and the elasticity is different from that of rubber or plastic. After we stretch to a certain length, the rebound often does not occur in a straight line with the elimination of external force. It will have a certain rebound lag after it is restored to its original shape mainly according to a specific slow curve. Due to the unique mechanical properties, leather clothes and leather shoes will not have a certain sense of pressure on the body when they are comfortable, and the wearing feeling outside leather shoes, rubber shoes and plastic shoes will be more different for different reasons.
Environmentally friendly leather is generally called artificial leather. The appearance of environmentally friendly leather is very similar to that of real leather, and it will be more similar in the hand feel of microfiber leather and leather. The biggest difference between artificial leather and real leather is that real leather has natural pores, while artificial leather does not. In terms of production, environmental protection leather has strict requirements in terms of process, from the selection of leather materials to the selection of chemical materials, with reference to many environmental protection indexes, and the main difference between many super fiber and xipi is that environmental protection leather, xipi and super fiber leather belong to man-made leather, and their main materials are made of resin.
Leather products have been favored by people for thousands of years, and have a long history of prosperity, with many irreplaceable and superior properties. In terms of the composition of animal skin, it is mainly made of collagen material, and because human skin is also made of collagen, the use of chemical materials can be continuously controlled in the process of processing, and all leather can have close contact with the human body at zero distance, which can be better worn close to the body and will not produce any adverse reactions against the human body, which is unmatched by many chemical fibers.
In order to facilitate our preservation and utilization in many times, people will generally give sufficient fresh fur for salt addition. In terms of salt, the weight will be reduced by 10% at most due to the loss of water. Therefore, many convenient ways to drain salt water are to place the fur pile in a place with a relative humidity between 70% and 90%, In order to better preserve the fur, we should be able to maintain our ambient temperature at about 10%.
Leather is generally made of natural leather, and in most cases, animal leather will process these fur, so that the fabric has better toughness and strength. The quality of leather is very excellent and the price is the highest among many leather. Therefore, many bad businesses will confuse the false with the true, Therefore, we should distinguish the authenticity of leather before we buy it.
