All kinds of leather-Global Information

Global leather types:

Cowhide, sheepskin, pigskin, other

Yellow cowhide, buffalo cowhide, tire cowhide

The characteristics of cowhide: Most of the cow hair is irregularly distributed in a single root, the pores are small and dense, and the grain surface is very fine. Secondly, the collagen fiber bundles in the reticulated layer of yellow cowhide are thick and compact, with good physical properties and high tensile strength. Moreover, the thickness of each part is relatively uniform and the difference between parts is small, so the utilization rate is large. is used the most.

Classification of sheepskin: divided into sheepskin and goat hair

The characteristics of sheepskin: dense coat, thin epidermis; small hair eye, arc-shaped distribution; low tensile strength (small width), large extensibility; large fat content, good warmth retention and good wear resistance.

Pig skin: Subcutaneous fat is developed, and the subcutaneous tissue is almost entirely composed of fat cells. Pig hair is generally arranged in groups of three in the shape of "pin", the hair roots are deep and concentrated in a fat cone. After the leather is made, the fat cells in the cone are removed, and many pits appear on the meat surface of the pigskin, commonly known as "oil nests". On the other hand, the grain surface presents tapered pores with a sharp outer circle and a sharp inner surface. The depth, size and density of pores are all related to the thickness of the grain.
