After the development of Rex rabbit production in the vast rural areas of China, a small amount of rabbit skin needs to be nitrated at home, requiring simple equipment, simple methods, and easy procurement of drugs. The method for producing rabbit skins suitable for processing and production in rural households is described below.

1. Soaked in soft home nitre rabbit skin, the general room temperature maintained at about 20 °C is appropriate. After drying, the rabbit skin should be cleaned with a blunt spatula to remove oil film and residual meat attached to the skin, and then immersed in clean water for 1-2 days so that the rabbit skin can be restored to the fresh skin state as much as possible.

2. Degreasing methods The quality of rabbit skins is a key factor in degreasing. The traditional method is to use sodium carbonate solution (2 g/l) to spread on the surface of the board to avoid liquid contact with the hair surface, so as to avoid rabbit hair brittle, wash with water after 10-20 minutes. Then use detergent powder (2 g/L) warm water to soak the skin after soaking and wash it with clean water after 10 minutes.

3 soaking the acid nipple by soaking, cleaning, regaining the rabbit skin can be dipping acid nitric acid skin. Use 20% mirabilite (sodium sulfate), 25% rice flour, liquid ratio 1:6-8 (measured by humidity) for 1-2 weeks. Hold the test by hand. If the skin is soft and not hard, then complete the nitric acid treatment. . Rice flour with glutinous rice flour or rice flour is appropriate, avoid using flour instead of flour, although it can ferment, but easy to stick hair, Nitrate is not easy to take off. After rabbit skin enters the nitrification solution, it should be turned once a day to make the temperature in the cylinder uniform. Nitrate skin should be promptly removed and allowed to dry. When the skin is half dry, it should be stretched four times to avoid excessive shrinkage of the skin.

4. Finish the work by dipping sour nitrite, dried rabbit skin, with a knife to repair the hard edge, and then rub the skin to soft cooked, shoot rice flour can be. If the “tank” phenomenon occurs on the surface of the tanned fur, the mirabilite in the skin is dissolved after being wetted with water, and the skin is bonded and hardened. The skin is in a state of skin and even hair loss occurs. 250 grams of chrome alum can be used. 250 grams, 25 grams of sodium carbonate treatment. First use 2.5 liters of hot water to dissolve chromium alum, cooling; 1 litre of warm water to dissolve sodium carbonate; cold water to dissolve 1.5 liters of salt. Then, the sodium carbonate solution was slowly added to the chrome alum solution, stirring continuously with a wooden stick, and then salt solution was added. The mixture was evenly applied on a "smeared-out" skin plate moistened with fresh water. The coated plate was left to stand on the surface of the plate for 4-5 hours, and was repeatedly applied 2-3 times until the mixture soaked through the skin. Then wash the skin with water to remove salt and sputum. After dehydration, flatten and dry.

5. Finished product preservation After finishing, take a clean rice noodle rabbit skin, under the strong sun exposure for several days, so that residual fat volatilize, eliminate odor, place an appropriate amount of camphor to prevent insects, cloth wrapped in summer. The finished product can also be processed into various fur products.
