Embodiment Construction

[0049] Dye the defective sheepskin blue boards into various color boards; grind the leather with a leather grinder and spray lining oil; use repairing cream to manually repair dry cracks and grass burrs, and smooth them with emery cloth; use a primer to seal the leather surface; Scrape once with the film coating agent, dry, mechanically lighten, pick out the cracks that have not been repaired, repair the grass thorns, and flatten with emery cloth; then scrape again with the film coating agent, dry, stretch, and mechanically emboss; Then use the film to scrape twice like the previous brush, mechanically soften the skin, pick the skin, and manually shovel the skin; spray the surface paste twice; spray the fixative;

[0050] Prepare the primer according to the following formula:

[0051] 10 kg of water, 8-12 kg of cationic composite resin, 3-5 kg ​​of non-ionic wax, 3-5 kg ​​of cationic wax, 3-5 kg ​​of cationic color paste, and 2-3 kg of weak cationic oil.

Abstract

The invention relates to a method for making high-grade sheep skin soft upper leather from inferior sheep skin, which comprises: dying, polishing leather, spraying sarcenet oil, mending, smoothing, grounding using grounding agent, brushing and scraping using multi-membrane agent several times, plucking skin, beating soft, scraping skin, Spraying surface slurry, spraying fixation agent, spraying hand feeling agent, ironing etc. Grounding agent is formulated by cation compound resin, non-ionic wax, cation color cream and water. Multi-membrane agent is formulated by non-ionic caseose-free color cream, compound resin, small molecule acroleic acid, swelling resin etc. Surface slurry is formulated by color cream, non-ionic wax, compound resin, silicon casein, flexible acroleic acid, paint slurry etc. fixation agent is formulated by water and aqueous gloss oil. Grounding agent is used mechanically and manually in the invention. Multi-membrane agent ,surface slurry and fixation agent have low cost , little pollution and can make high-grade sheep skin soft upper leather from inferior sheep skin.

Description

technical field [0001] The invention relates to leather processing technology. Background technique [0002] Existing high-grade sheepskin supple leather such as garment leather, bag leather, sofa leather and shoe upper leather can only be processed with high-quality sheepskin blue board. A large number of defective sheepskin blue boards, such as residual boards, ringworm boards, grass thorn boards, etc., cannot be processed into high-grade sheepskin soft leather with the existing technology, and can only be treated as defective sheepskins at low prices. It is economically uneconomical and causes a waste of resources. Contents of the invention [0003] The present invention provides a method for making high-grade sheepskin suede from defective sheepskin blue board, the method comprising the following steps: [0004] a. Dye the defective sheepskin blue board; [0005] b. Grinding leather and spraying lining oil; [0006]...
