In terms of seat leather, leather and imitation leather are mainly used, and common imitation leather can be Pu, PVC and so on. Leather is mainly made of raw cow leather through dozens of complex processes. The first layer of leather is also relatively better than the second layer of leather. There are relatively few natural defects in leather, and the level of leather is relatively high. The leather surface with few defects does not need to be polished and modified frequently, and can be well made into our full grain leather. The dough with more defects will be relatively easy to become our grinding skin after our modification.
With the continuous improvement of the quality requirements of raw materials, it will be relatively common in the field of medium and high-end automobiles, and these raw materials can only be used in a super luxury brand automobile with more than one million levels. The higher the grade of leather, the higher the quality of the raw materials selected, the less the number of processes required to be processed, and the lower the processing depth, so as to retain the main natural style of leather.
The regenerated leather can be processed after crushing the leather or leather of various animals and blending the chemical raw materials. Under the surface processing technology, it can be the same as the leather shaving leather and embossed leather
The main reason is that the edges of leather sheets are relatively neat, the utilization rate is relatively high, and the price is relatively cheap. However, the leather body is relatively thick and the strength is relatively poor. It can only be used to make cheap belts and qualitative craft products such as tie rod bags, briefcases, club covers and so on. The fiber structure in the longitudinal section is relatively uniform and consistent, so the coagulation effect of the mixed fiber fluid can be well recognized. "
In terms of vegetable tanning leather, it is mainly a kind of cow leather of our vegetable tanning agent, and generally speaking, it presents a relatively light yellow in color, and also has white pink and ivory white. For the flexible leather material, it will obviously become soft and plastic after absorbing water, and it is very suitable for making our leather crafts or leather carving works. With the passage of time, the color of vegetable tanned leather is also deepening. Sometimes it can be used to judge whether the purchased primary vegetable tanned leather is the leather material in stock. If the vegetable tanned leather has a tendency of yellowish brown, whether it is the leather material that has been placed for a long time.
If the tanning oil is deep enough, the color of the leather can be deepened quickly within six months. However, if vegetable tanned leather is dyed, it will not change color in use. The picture shows the color difference of the same vegetable tanned leather product after using it for different times under good maintenance conditions.
