Problems solved by technology

[0003] The first layer of cowhide is usually used as the surface material of daily necessities, while pigskin leather has large pores, rough surface, and large differences in fiber tissue due to its own characteristics, so the gloss of the obtained leather is not high. Especially the second-layer pigskin material, although its material cost is lower than that of the first-layer pigskin, its pores are large, and some parts of the skin embryo may even have uneven defects. The material fineness of the second-layer pigskin material is not enough and the material gloss is poor , so it can only be used to make the inner lining of the leather, and cannot be used as the surface material of the product, the application range is limited, and the economic benefit of the leather is not high

Abstract

The invention relates to the technical field of leatherworking, and particularly relates to a production technology for preparing leather from pig split leather scytoblastema. The production technology comprises the following working steps: selecting materials, spraying and filling resin, scraping and repairing, drying, flattening, rubbing down, spraying a covering coating, and pressing by plates. According to the production technology disclosed by the invention, the loose side parts on the pig split leather scytoblastema is sprayed and filled with the resin, then the irregular parts on the surface of the scytoblastema are scraped in a scraping and repairing manner, then the surface of the scytoblastema of the pig split leather is smoothened and flattened by drying, flattening, rubbing down, spraying the covering coating and pressing by the plates, so that the quality of the prepared leather can reach the level of cowhide and the added value of the leather can be improved.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a production process for preparing leather by using two-layer pigskin embryos. Background technique [0002] Leather is widely used on the surface of daily necessities, such as tables and chairs, sofas, shoe materials, clothing, etc., to add texture, beauty or durability to daily necessities. Leather can be broadly classified into artificial leather and natural leather. Natural leather refers to taking animal fur and drying, cleaning, softening, dyeing, trimming, cutting and other production processes to form a smooth surface and tough texture. [0003] The first layer of cowhide is usually used as the surface material of daily necessities, while pigskin leather has large pores, rough surface, and large differences in fiber tissue due to its own characteristics, so the gloss of the obtained leather is not high. Especially the second-layer pigskin material, although i...
