Characteristics of various leather materials for notebooks:There is a video


There are many kinds of leather, and different kinds of raw leather and different tanning methods can be used to make leather suitable for various purposes. Commonly used leather for genuine leather products has the following characteristics.

(1) Features of cow leather

Cow leather includes cattle leather, yak leather and buffalo leather.

Yellow cow leather has fine grain, thick cortex, high strength, fullness and good elasticity, so its products are beautiful, comfortable and durable. Yellow calf leather is mainly used for clothing, leather shoes, bags and ball games.

The grain of cow leather is slightly worse than that of yellow cow leather, and its other properties and uses are roughly similar to that of yellow cow leather.

The surface of buffalo leather is relatively rough, the fibers are loose, the strength is slightly lower than that of yellow cow leather, and other properties are close to that of yellow cow leather. Buffalo leather is mainly used to make sofas and bags, and is also commonly used to make leather shoes.

(2) Characteristics of pig leather

Pig leather is quite different from cow and sheep leather, mainly reflected in rough grain, tight fibers, plumpness and poor elasticity, but the strength of pig leather is similar to that of cow leather and higher than that of sheep leather, so its products are durable. Aesthetics are poor.

Pig leather can be used in the crafting of various leather goods.

(3) Characteristics of sheep leather

Sheep leather is divided into goat leather and sheep leather.

The grain of goat leather is fine and beautiful, and its softness is good, but its fastness is worse than that of cow leather. Goat leather products are beautiful and comfortable, but the surface friction resistance and durability are average. Goat leather is mainly used in the production of high-end women's leather shoes, clothing, gloves and women's handbags.

Sheep leather is softer and softer than goat leather, but not as strong as goat leather. Sheep leather products are more beautiful and comfortable to wear, but have poor durability. Sheep leather is mainly used in the production of clothing and gloves, as well as high-grade leather shoes and soft bags.

(4) Characteristics of full grain leather

Full-grain leather refers to the leather that retains and uses the original appearance of animal skin (the side where the hair grows), also called front leather. Some full-grain leathers are used directly without finishing, but most of them are treated with cosmetic finishing.

Full-grain leather requires high-grade raw material leather with less disability and high processing requirements, so full-grain leather is high-grade leather. Since the surface of the raw leather is completely retained on the leather, its fastness performance is good. Generally speaking, the surface of full-grain leather is not coated or the coating layer is very thin, which maintains the softness and good air permeability of the leather. The grain of genuine leather is used to reflect the natural style, making it comfortable and beautiful.

Most of the full-grain leather is dyed with dyes, so the industry usually refers to the full-grain leather with dye as the main colorant of the coating as aniline leather (or full aniline leather). This kind of leather is evenly dyed, with clear grain, without using any film-forming substances with covering effect, and the grain grain of the leather surface is not covered by the flow at all and is preserved; only a thin colorless and transparent grain is left on the modified leather surface. You can clearly see the grain of the leather itself.

Full grain leather is used for all fine leather goods. When cleaning and caring for such leather products, attention should be paid to maintaining its unique style and feel.

(5) Characteristics of semi-aniline leather

There are some but very shallow defects on the grain surface of the raw material of this kind of leather. In order to cover the defects while retaining the natural grain of the leather, a small amount of pigments, adhesive film-forming agents and dyes should be used to lightly spray and color the leather to form A semi-covering layer with a very thin coating that makes the grain of the leather barely visible.
