Problems solved by technology

[0003] Cow split leather is mainly close to the reticular layer of leather, which is composed of coarse collagen fiber bundles woven in three-dimensional space. The collagen fiber bundles are loosely woven, which makes the wear resistance of cow split leather poor and shortens the service life of cow split leather. short

Abstract

The invention discloses a formula for improving wear resistance of cow split leather, a treatment process and processing equipment, and relates to the technical field of leather processing. The formula for improving the wear resistance of the cow split leather consists of the following components in parts by weight: 13-18 parts of silicate ester, 2-5 parts of nano silicon dioxide powder, 1.6-2.8 parts of silicon carbide whiskers, 3-7 parts of sulfonated castor oil, 0.5-1 part of super-hydrophobic silicon dioxide, 1-3 parts of emulsified silicone oil, 3.3-5.6 parts of terpilenol and 22-30 parts of distilled water. Silicate ester, nano silicon dioxide powder, silicon carbide whiskers, sulfonated castor oil, super-hydrophobic silicon dioxide, emulsified silicone oil, terpilenol and distilled water are used as raw materials for preparing the formula for improving the wear resistance of the cow split leather, and the nano silicon dioxide powder and the silicon carbide whiskers are used as filling materials. The surface smoothness of the cow split leather is reduced by the nano silicon dioxide powder and the silicon carbide whiskers, the friction force of the surface of the cow split leather is reduced, and the wear resistance of the cow split leather is favorably improved.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a formula for improving the abrasion resistance of bovine split leather, a treatment process and processing equipment. Background technique [0002] There are various tanning methods of leather. According to different tanning methods, leather can be divided into: vegetable tanned leather, chrome tanned leather, oil tanned leather, aldehyde tanned leather, aluminum tanned leather and mixed tanned leather. At present, chrome tanning is widely used because of the advantages of shorter time, lower cost, soft texture of chrome tanned leather, less fading and shrinkage, and convenience for subsequent processing. Chrome tanned leather is generally blue-white, also known as wet-blue leather. Generally, wet-blue leather can be processed into various styles of finished leather. [0003] Cow split leather is mainly close to the reticular layer of leather, which is composed of co...
