Abstract

The invention discloses a sheepskin soaking method. The sheepskin soaking method comprises the following steps: (1) putting gauze into medicinal liquid with a temperature of 80 to 90 DEG C, fully dipping the gauze in the medicinal liquid, then taking out the gauze, uniformly covering sheepskin with the gauze, removing the gauze in 4 to 6 min and repeating the above operations twice; (2) soaking the sheepskin in a soaking solution with a temperature of 10 to 13 DEG C for 3 to 4 h; and (3) irradiating the soaked sheepskin with purple light for 20 to 30 min, wherein the intensity of the purple light is 180 to 200 lux.

Description

Technical field [0001] The invention belongs to the leather manufacturing field, and specifically relates to a method for soaking sheepskin in water. Background technique [0002] Leather is an animal skin that has been denatured and is not perishable through physical and chemical processing such as dehairing and tanning. The leather is composed of natural protein fibers tightly woven in a three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. The leather industry covers major industries such as tannery, shoemaking, leather clothing, leather goods, fur and their products, as well as supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories. The upstream and downstream are highly correlated, relying on market pull, and the products are evergreen, integrating foreign exchange earning, enriching people, and employment. After adjusting and optimizing its structure...
