Processing method of mink skin

First, the main raw material: mink.

Second, equipment: knives, planks, etc.

Third, the production method: first kill the marten. The main methods are as follows:

1. The method of breaking the cervical vertebra: grasp the neck of the mink with one hand and the head with the other, push hard from back to front to break the vertebrae. When you pay attention to nostril bleeding, wipe it out immediately. Prevent contamination of fur.

2. air injection method: use a syringe to directly inject 5ml of air into the mink's heart.

3. Injection poisoning method: inject strychnine nitrate with a concentration of 0.03%, 0.05%, 0.7 ml and inject into the chest cavity. Pay attention to this method after killing, do not stack together, in case of hair loss. In addition, the remaining mink should not be fed to other animals.

After killing the marten, it is followed by skinning. Skinning technique is also crucial. The usual method is to open the crotch first, that is, with the tip of the knife (or scissors), from the center of the toe of one hindlimb, along the midpoint of the dividing line of long and short hairs on the inside of the hindlimb, to the toe center of the other hindlimb, and then from the midpoint of the midline of the ventral side of the tail to the trailing edge of the anus, and then to the palms of two rear claws to remove a small piece of three angles. Under the knife to be correct, do not break the anal gland, in order to prevent the formation of size or skew phenomenon. First, peel off the hindlimb, when peeling to the knee joint, peel to the toe bone with a knife, cut off two segments, leave the first toe bone with claw skin on the skin, let the skin wrap around the skin, then peel off the tail, around the genitals and buttocks, remove the coccyx, hang one hindlimb upside down, pull the skin plate down evenly with both hands, take it off to the forelimb, peel off the forelimb, and then continue to peel forward to the ear root and eye socket. Use a knife to cut the base of the ear shell, the orbit and the tip of the nose close to the skull to keep the ear, orbit and nose intact. The leather last is loaded by the method of loading the last board in the Mao Dynasty. Then use a scraper to scrape off the oil, the tail, the hind limbs and the residue on the edge of the leather plate. Dry in a dry place, when drying to 60% or 70%, turn the plate hair to dry outward, and the water content shall not exceed 15%. Then use sifted sawing wood, add appropriate amount of detergent to scrub the dried mink board, scrub the grease and dirt clean until the skin board is dry and free from sawdust. Wash the fur again until the plush is clean and shiny. Finally, gently tap the fur with a stick to bounce off the sawdust. Mink skin should be processed and finished after drying, first scrub with sawdust, and then scrub the quilt with alcohol or gasoline with towels to make the plush look beautiful, clean and shiny. For some curved hairs, you can use towels dipped in 70 ℃ ~ 80 ℃ hot water, wring dry, and pick up curved hairs several times. There are 95% to 98% variable straight hairs. Comb the knotted hair with a comb to mend the hole. According to the male and female classification, back-to-back, belly-to-belly stack, pressing with the appropriate weight of smooth wood for 10 to 15 hours, it can be sold.
