How to manually tan rabbit skin?

The purpose of tanning rabbit skin is to change the shortcomings of the skin becoming hard after drying, making it soft and tough. The skin plate is composed of three parts: epidermis, dermis and subcutaneous loose tissue. The dermis is the most developed, with many criss-crossing collagen fibers. These fibers are very tough and can make the skin strong. However, the collagen fibers harden when they dry up, making the entire skin hard. If the characteristics of the fibers can be changed, the The purpose of tanning is achieved without affecting its strength. Now we will introduce a simple tanning method for rabbit skin. (1) Washing and cleaning: Lay the fresh rabbit skin flat on the board and use a knife to scrape off the skin, muscle, fat and blood, especially the fat.

To submerge the rabbit skin, turn it every 4 to 5 hours. 1 time. After about 8 to 10 hours, the collagen fibers that make up the skin plate expand in the acidic solution, making the skin plate thicker and smaller in area.

Dissolve the skin salt into 250 ml of hot water, add 250 grams of coarse grain powder to make a coating, apply it evenly on the leather board, and press it gently with the palm of your hand. The skin salt will slowly penetrate into the expanded collagen fibers after one day and night. Cut off a small piece of edge and remove the paint. When the edge is 70 to 80% dry, pull it back and forth with force. If the subcutaneous tissue becomes white and loose, it means the skin has been thoroughly eaten, and all the paint can be removed from the entire rabbit skin (the paint can be Use again). After the rabbit skin is 80% dry, rub the rabbit skin from all directions to change the position of the collagen fibers until the skin returns to its original size and the loose tissue under the skin becomes white and velvety. Allow the rabbit skin to dry completely, pat the skin clean, and comb the coat to create a soft, smooth rabbit skin. #N'z-{#S;B$O9J!r Pay special attention to the entire tanning process.
