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

Example Embodiment

[0053] Example 1

[0054] The production process of using two-layer pigskin skin embryos to prepare leather in this embodiment includes the following processing steps:

[0055] Step (1). Material selection: buy two layers of pigskin leather as the skin embryo;

[0056] Step (2), spray filling resin: spray filling resin on the loose surface area of ​​the crust surface; filling resin is a filling acrylic resin;

[0057] Step (3), scraping: use a scraper to scrape and fill the patching cream on the surface of the skin embryo to form a scraping coating;

[0058] The repair cream includes the following raw materials in parts by weight: 80 parts of polyurethane, 60 parts of acrylic acid, 100 parts of acrylic polymer composite resin, 30 parts of self-crosslinking acrylic acid, 30 parts of release wax, 1 part of silicone oil, 5 parts of ethanol, 100 parts of water.

[0059] Step (4), drying: put the scraped skin embryo into an oven for drying, the drying temperature is 60 ℃, and the drying tim...

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...
