Embodiment 1
[0021] Embodiment 1: According to weight ratio 99~90% of corium fiber, 1~10% of textile fiber.
[0022] (1) Screen the broken skins, then wash them, and then block them. The scraps of skin are leather scraps or waste leather products of one or more animals selected from cattle, sheep, horses, pigs, dogs, deer, rabbits, crocodiles and snakes.
[0023] (2) Physically and chemically treat the selected pieces of skin, comb and pack them into bags, then put the leather fibers into the warehouse and open them with a fiber opener.
[0024] (3) After the leather fiber is loosened, use a measuring container to quantify it, mix it with the textile fiber, and then perform cross-lapping to form an animal leather fiber layer. According to the weight ratio, the leather fiber is 99~90%, and the textile fiber is 1~10%. %, where the textile fiber is a blend of cotton and acrylic fibers. It should be understood that the textile fiber may be any high strength, low melting point spinnable natur...
Embodiment 2
[0028] Embodiment 2: 100% according to weight ratio corium fiber.
[0029] (1) Screen the broken skins, then wash them, and then block them. The scraps of skin are leather scraps or waste leather products of one or more animals selected from cattle, sheep, horses, pigs, dogs, deer, rabbits, crocodiles and snakes.
[0030] (2) Physically and chemically treat the selected pieces of skin, comb and pack them into bags, then put the leather fibers into the warehouse and open them with a fiber opener.
[0031] (3) After the leather fibers are loosened, use a meter container to quantify them, and then perform air-laid netting to form an animal leather fiber layer.
[0032] (4) The semi-finished animal leather fiber layer is impregnated in a special leather adhesive, and the leather adhesive is composed of the following parts by mass: 50 parts of natural latex, 25 parts of polyvinyl alcohol, 25 parts of of acrylate and 25 parts of urea.
[0033] (5) Interweave and shape the animal ...
Embodiment 3
[0036] Embodiment 3: According to weight ratio 90% of corium fiber, 10% of textile fiber.
[0037] (1) Screen the broken skins, then wash them, and then block them. The pieces of broken leather are the leather leftovers of cowhide.
[0038] (2) Physically and chemically treat the selected pieces of skin, comb and pack them into bags, then put the leather fibers into the warehouse and open them with a fiber opener.
[0039] (3) After opening the leather fibers, use a measuring container to quantify them, mix them with textile fibers, and then perform cross-lapping to form an animal leather fiber layer. According to the weight ratio, the leather fibers are 90%, and the textile fibers are 10%. Fiber is a blend of cotton and acrylic fibers (50 / 50).
[0040] (4) Impregnating the semi-finished animal leather fiber layer in a special leather adhesive, the adhesive is composed of the following components by mass: 40 parts of natural latex, 20 parts of polyvinyl alcohol, 30 parts of ...

Abstract
The invention discloses an animal fiber non-woven fabric. The animal fiber non-woven fabric at least comprises an animal leather fiber layer soaked with leather binding agents, and the animal leather fiber layer is formed by conducting lapping machining on bundle-shaped leather fibers obtained by fiber dissolving of the animal skin. The invention further discloses a production method of the animal fiber non-woven fabric. The production method includes the steps of screening, washing and blocking scrap leather blocks, conducting carding and bagging after physicochemical processing, then conducting warehouse entering and loosening on the leather fibers, conducting quantification with a metering container, conducting lapping on the leather fibers to form the animal leather fiber layer, soaking the animal leather fiber layer in the specific leather binding agents, conducting interweaving shaping on the animal leather fiber layer and textile fiber gridding cloth in a hydroentanglement method, conducting drying, winding and splitting on the animal leather fiber layer and the textile fiber gridding cloth after physicochemical processing, forming the animal fiber non-woven fabric, and finally packaging the animal fiber non-woven fabric. According to the animal fiber non-woven fabric and the production method of the animal fiber non-woven fabric, various high-quality physical properties of the original leather fibers are retained, various materialization indexes can meet the requirements of different products, and the animal fiber non-woven fabric has the advantages of being low in cost, high in yield, high in economic benefit and the like.
Description
technical field [0001] The invention relates to the textile field, in particular to an animal fiber nonwoven fabric and a production method thereof. Background technique [0002] At present, the utilization of animal skins is mainly processed into leather sheets, which are used to make leather shoes, clothing or leather products. The rate is very low, and most of the leftovers have become wastes. These leftovers not only pollute the environment, but also this natural and valuable protein material cannot be used scientifically and rationally. [0003] People are well aware of the high-quality characteristics and high cost performance of animal leather fibers. Many scientific research institutions, enterprises, and colleges around the world have continuously researched, developed and utilized these leather fibers to realize their use value, and various processes have emerged in an endless stream. At present, the process that can realize industrialization mainly uses the glue ...
