Embodiment 1

[0014] All domestic materials are used, and the pigskin is washed in drums and stuffy water for 8 minutes, and then washed and soaked in water.

[0015] Rawhide 2400 catties water remaining part

[0016] Water-emulsion type degreasing agent 35 catties weather temperature 25 ℃

[0017] Soda ash 20 catties, water temperature 20 ℃

[0018] Return to the state of fresh skin, the whole skin is soft, no hard core on the buttocks and back, wash with water, expand with alkali, bulge for 170 minutes, then soften for 90 minutes, and then treat according to the usual procedures to solve all technical defects.

Embodiment 2

[0020] Rinse with water for 3 minutes

[0021] Rawhide 2400 catties water remaining part

[0022] Water-emulsion degreaser 37 catties weather temperature 30 ℃

[0023] Soda ash 20 catties, water temperature 20 ℃

[0024] time 2 hours

[0025] Soda liming for 165 minutes, then ditto. Achieve process quality effect.

Embodiment 3

Abstract

The invention discloses an improvement method for solving all defective workmanship before the pickling of leather, and the application. The method comprises soaking technology, barilla-soaking technology and softening technology. The invention discloses the method for solving the defective workmanship such as loose leather surface, poor position, tearing, villus feeling, collagen change, splitting and uniform scraping, etc, and simplifies the process flow.

Description

technical field [0001] The present invention relates to solutions for loose leather surface, poor position, collagen denaturation, fluffy feeling, tearing, shaving, and flake skin, and can simplify the process flow, and the application on fur, especially relates to the improvement of pigskin technology method. Background technique [0002] The global leather industry only theoretically says that the raw hide should be restored to the state of fresh leather in the water soaking process, but it has not been done in practice. The immersion chemicals used are preparations; detergent, washing powder, enzyme preparation, soaking agent, wetting agent. Alkaline materials such as soda ash. The hair removal process uses enzyme preparations (in the research and test phase) and ash-alkali processes. The chemical materials used are available in all countries in the world, the process is uneven, and there is no unified standardized production. "China Leather", China Leather Associatio...
