At present, the market is used as a material for automotive leather seat covers, and most of them are not automotive professional materials. But it is often said to be imported high-quality professional car leather. According to practitioners who have been engaged in car seat covers for many years, the awareness of automotive leather materials is generally low, lacking the necessary knowledge and actual identification level. In view of this, this information will introduce and mention the knowledge of cattle breed, cow age and gender, organizational structure, cowhide level, origin and other aspects, and analyze and explain its misunderstanding. Finally, it will also be the excellence of leather leather. Part of the nirvana is displayed in the back, I hope to help you with the choice of leather leather seat cover for your S30.
A: The characteristics of the species and structure of the cattle According to the type of cattle can be divided into yellow cowhide, buffalo leather, yak leather, yak leather. * Yellow cowhide: small pores, mild papilla, about 0.09mm. The grain is fine. The nipple layer is thin, and the upper collagen fiber bundle is small and tightly woven. However, the distribution density of the fibers in the lower layer decreases. The elastic fibers in the nipple layer are more developed. The reticular layer is thick, the collagen fibers are thick, the weaving is also very tight, and the tensile strength is large. The width is larger and the difference is smaller. Very popular with S30 for the car leather seat cover consumers love. But improper tanning, easy to loose surface * Buffalo: large pores, mastoids are particularly noticeable, about 0.16mm. The grain is rough. Its special grain pattern is also loved by consumers. The nipple layer is thin, the collagen fiber bundle is small, and the weaving is very tight. The collagen fiber bundle between the nipple layer and the reticular layer is relatively tightly woven. Not easy to loose. The reticular layer is thick, the collagen fibers are coarse, but the weaving is loose. * çŠ leather: between yellow cattle and buffalo. The width is large and thick. * 牦 cowhide: the pores are small and dense, and the mastoids are slightly higher than the yellow cowhide, about 0.09mm. The grain is fine. The nipple layer is thin, the collagen fiber bundle is small, and the weaving is tight. The distribution density of the lower collagen fibers is reduced. The mesh layer is thick, the collagen fibers are thick, and the weaving is loose. The width is slightly smaller than that of yellow cowhide, and the difference is more. Improper tanning, easy to loosen. Experts: Because the number of yak is small, the yak's leather fly infection rate is high, and the bruise is serious, so the car leather uses yellow cowhide and buffalo.

Second: the relationship between cattle age, gender and quality In addition to the type of cattle, there is a significant difference in the quality of cattle age and gender. The following is an example of yellow cowhide:
1: 犊 cowhide: The grain surface is smooth and delicate, with less damage. The fiber bundle is fine, the nipple layer is relatively thick, the width is relatively small, and the quality is high.
2: 阉 cowhide: The grain surface is relatively fine, the fiber structure is tight, the strength is good, and the width is large. High quality.
3: Heifer skin: The grain surface is relatively fine, and the fiber is similar to the cowhide. High quality.
4: Cow skin: The fiber is loose, the elasticity is poor, and there are many defects in the growth period. Low quality.
5: Male cowhide: Relative to yak leather, its grain surface is rough, the fiber bundle is thick, the weaving is slack, and the neck is wrinkled. Low quality.
6: Fetal cowhide: The grain is fine and the width is small. The fiber bundle is thinner, the strength is poor, and the quality is low. Expert Tips: The above three kinds of cowhide are better, the leather seat cover is the best for the leather, and the other leather products are the best.
Three: The layer of cowhide leather is divided into the top layer and the second layer according to the level (three layers, four layers and two layers are slightly different, but all are classified into the second layer category), the first layer and the second layer skin are both from the sense of appearance and texture. Physical and chemical properties, organizational structure, or service life, price, quality, etc. have obvious differences. Expert Tips: It is recommended to use the top layer leather material when installing the car leather products, and the second layer leather is generally not suitable as the car leather seat cover according to the current tanning technology. Attention should be paid when choosing. IV: Origin and quality The quality of the world's leather is best in Europe. The output and quality are Italy, Germany, the Netherlands, the United Kingdom, Spain, France and so on. More than 50% of the EC's cowhide can be used as high-quality leather, and leather in other countries is beyond the reach. Expert Tips: Due to the high quality of the European Union's cowhide, many people will advertise the use of Italian and German leather. When choosing leather, pay attention to it. Whether it is Italian, German leather or imported professional leather, it can be through the width, texture, color, The unique styles of luster, texture, fiber, smell, logo, etc. are judged comprehensively and require real professionals to understand.
