How to burn the wool of sheepskin?

Sodium hydroxide can be used to cook fur.

The cooking steps of cooked sheepskin are as follows: checking the skin → soaking → scraping the inside of the meat → cleaning → lowering the tank → watertight → scraping the inside of the meat for the second time.

(1) Check the skin graft, unfold the skin graft to be cooked, see if there is any crack, wrinkle and rotten hair on the skin graft, and remove impurities stuck on the sheepskin.

(2) Soaking: put the sheepskin into a vat and soak it in water. Soak 1 day in summer and 2-3 days in winter.

(3) When scraping meat, spread the skin with the inner side facing upwards horizontally on the wooden pole, and scrape off the residual meat and grease with a knife.

(4) After the meat is cleaned, rinse it with clear water, and then add detergents such as alkali, soap and washing powder to scrub the fur until it is cleaned.

(5) Add salt, mirabilite, flour and water into the jar and soak the skin in the jar. The function of adding salt is to protect wool, the function of adding mirabilite is to soften leather boards, and the function of adding flour is to protect fur and absorb oil stains.

(6) Smooth dry skin and spray a little water on the skin until the skin is moist. Never spray too much water. Then put every two skins together and put them in the shade 1-2 hours.

(7) The second scraping of meat is to soften the skin, and a blunt knife must be used, first with a horizontal shovel and then with a flat shovel. After shoveling dry, you can cut clothes.
