Interpretation Of Performance Characteristics Of Leather Materials

< p > < a > href= > //www.sjfzxm.com/news/index_c.asp > > hunting skin > /a >: the characteristics of subcutaneous fat are developed, and the hunting hair is three groups as a group, which is deep in shape and deep in the whole dermis. The root of hair is concentrated in a fat cone. After making shoes, the grain is coarser and less smooth than the cow skin. Secondly, the fiber bundles of the skin hunting are thicker and interweave densely. Therefore, they have greater strength and wear resistance. At the same time, the weaving pattern of their fiber bundles varies with the different parts of the skin.

< /p >

< p > cattle hide and yellow cattle skin: they are characterized by small pores, fine grain surface, thin surface, strong tensile strength, uniform thickness and poor location, and high utilization rate. Their buttocks are closely knit, and the fibrous tissue of the abdomen and shoulders is loose; the axilla is more soft and thin, but the occupancy ratio is very small.

< /p >

< p > buffalo skin: characterized by long hair, thick fiber, loose tissue, large part of the body, and back of the Gadfly eye or the bottom of the Gadfly.

Compared with yellow cattle skin, the fibers are thinner and slightly softer, second only to yellow cattle hide.

< p > > a href= "//www.sjfzxm.com/news/index_c.asp" > sheepskin < /a > sheep skin: the characteristics are dense sheepskin, thin skins, low tensile strength, high elongation and large fat content. Therefore, it is made of fur and has good warmth retention property and leather is soft and comfortable.

< /p >

< p > goat skin: the appearance is similar to coarse wool sheep skin, and its grain is smooth and meticulous.

Fiber bundles are more tightly knitted than sheep skins.

Fiber bundles are also more robust. Leather is soft and stretches. The thickness of the neck and abdomen varies greatly, and the sheepskin is more resistant to folding.

< /p >

< p > miscellaneous skin and horse hide: its parts are closely different. The horse's stock is very hard, and its water permeability and air permeability are small.

< /p >

< p > deer skin: it refers to the skin of family deer, wild deer and chamois.

The characteristics are soft, large porosity, toughness and extension.

< /p >

< p > all natural leather products have extensibility, breathability and water absorption.

< /p >

< p > synthetic leather < a href= "//www.sjfzxm.com/news/index_c.asp" > shoe making < /a > production has been widely used, its main characteristics are as follows: < /p >

P > corrosion resistance: the surface of synthetic leather is coated with plastic, so it is not easy to contact with mild acid and alkali, and the chemical reaction and moth resistance are also good.

< /p >

< p > Water Repellency: synthetic leather has better waterproof performance, moisture is not easy to penetrate into the inner layer, and can be scrubbed with wet cloth after surface contamination, and its luster is inconvenient.

< /p >

< p > smooth surface and uniform material: because the surface coating has no defect, the leather surface is smooth, beautiful, bright and colorful, and the material thickness is uniform.

< /p >

< p > poor permeability: the fibrous structure of the base is sealed by the coating on the surface, so its air permeability is poor.
