Goose down suede is a high-grade suede product with the characteristics of strong, soft and white fur. Its resistance to hair removal is stronger than that of rabbit hair. Its fluffy properties are superior to that of tanned hides, and its moisture-proof and cold-proof properties are comparable to that of fox fur. Goose down suede can be used to make all kinds of clothing, hats, scarves, shawls, etc., dressed in cold and warm, beautiful, elegant and luxurious, favored by consumers at home and abroad, has a broad prospect for development. The goose fur processing technology is introduced as follows. First, the peeling method of raw goose peel 1, the selection of high-quality goose goose is the basis for the production of high-grade goose feathers. 1 Select large adult geese, weight should reach 4 kg or more, so that the production of large skin, compact structure, strong wear resistance; 2 choose more hair goose, mainly to see the goose's abdomen, touch the furry, eyelid abdomen fullness ;3 Select the color of the coat, which can be determined according to the needs of the manufacturers. Generally, it is mostly white, but there are also manufacturers to produce variegated hair color varieties. 2, pull the hair will choose the good goose before the slaughter to take 25 ml of white wine, when the goose is drunk, pull out big feathers and hair pieces, leaving the hair (live goose feathers is the advantage of the goose body itself protective, pull hair After the skin does not leave a large feathered burrow). The order is to plucking wings first and big hairs in tails; then to pull out the neck, chest, abdomen and leg hairs. 3. Slaughter is preceded by a person who places the goose's wings on his back against the back, and holds the goose's feet to keep it from moving. Another person kills a goose with a knife, holds a knife in one hand, holds the goose head in the other hand and stretches the gooseneck. There is a slightly concave skin groove in the neck of the goose, with jugular veins and arterial vessels buried inside. Insert the knife into the skin groove at the upper 1/3 of the gooseneck, and cut the neck meat 3 to 5 centimeters longitudinally along the direction of the neck. Then cut the cervical and aortic blood vessels transversely in the middle of the cut, and place the blood in the bowl and cut it. Do not dye wool; when the blood is drained and the air has not been cut off, turn the knife around the head-neck joint and cut off the skin attached to the head and neck, exposing the muscles and tie it with a rope, slamming the rope on one foot to prevent the goose from rolling. At the same time, use a knife to insert the lower part of the incision, along the goose's midline back to the anus to break the goose skin, then the goose can be hung up and peeled. 4, peeling and peeling operation is the key to ensure the quality of the skin. The knife must be properly handled and flexible. One must ensure the integrity of the skin; two must not leave too much fat. Spread the sawdust on the knife edge to remove fat and blood from the skin and prevent it from contaminating the skin. The order of peeling is to peel the neck, back, and then the underside of the armpit. When peeling to the root of the wings and legs, it should be from the back of the wings and the back of the thigh. Cut the four tips at right angles to the carcass, peel them to the elbow and the hocks, cut a circle with a knife, and peel off the fur on the upper part of the wings, leaving only the wing tips and legs; when peeling back the fur, because the back is under the skin Less fat, difficult to peel off with muscle adhesion, must be carefully peeled, do not tear skin, peel back after peeling off the abdomen, this part of the subcutaneous fat, peeling should pull the skin tightly with the left hand, right hand with peeling Pushing can easily peel off the skin, peel to the anus, cut the anterior part of the tail to the anus, and then cut it with a knife, peel the skin around the anus, and then peel the entire skin. Second, the rough raw raw skin goose peel peeled immediately after cleaning, scraping the remaining meat and fat on the skin, available scraper or manual operation. When scraping the board, it is necessary to scrape it from the end to the end of the head, and the force should be even. Even the scraping edges should be rubbed with a towel, sawdust, etc. to prevent the oil from contaminating the goose fur. After cleaning, anti-corrosion measures are taken as soon as possible because the fresh skin contains water, proteins, fats and enzymes, which are easily caused by the autolysis of the enzymes in the tissues and the infiltration by microorganisms. Antisepsis can be naturally cloudy or salted. 1, the natural shade dry method will be flattened nailed on the back of the wood, the fur down, the skin up, placed in the shade of the air circulation dry. As the goose's fat melting point is very low, it will melt at 20-30°C and diffuse into the skin, making processing more difficult. 2. Salting method 1 Salting method: Spread salt evenly on the surface of raw hides, use fresh salt for 20-30% of the weight of the skin, and mix the skin with the skin after salting. Shake off the salt and dry it afterwards; 2 Salt immersion: Soak it in 25% salt water for 24 hours, remove it, and place it in the same way for 5 days. Spread and dry. Drying method with the natural dry method. Regardless of whether it is natural dry or salted, the temperature should be 10-20°C and relative humidity 60-70% when the skin is being dried. After the dry skin moisture is reduced to 10-20, it can be stored in storage. It should be placed in a well-ventilated place and stacked in groups. It is advisable to have no more than 30 pieces of each pile, and insect repellents should be distributed to the tanneries.
