Definitions

  • the invention relates to a novel fabric and a brand new leather product in which a collagen fiber bundle forms a network structure.
  • the leather is mainly made of animal skin.
  • the longitudinal section of animal skin is divided into three layers: epidermal layer, dermis layer and subcutaneous tissue.
  • the dermis is between the epidermal layer and the subcutaneous tissue.
  • the dermis is divided into the nipple layer and the mesh layer.
  • the nipple layer is a thin layer of loose connective tissue next to the epidermal layer, protruding toward the epidermal layer to form a dermal nipple; after the leather is formed, the surface of the nipple layer is also called the grain surface of the leather, so the leather industry calls this layer the grain surface layer.
  • the mesh layer is a thick dense connective tissue under the nipple layer. The thick collagen fiber bundles are interwoven into a mesh, which gives the leather greater elasticity and toughness.
  • Tanning refers to the process of tanning raw hides into leather.
  • the hair and non-collagen fibers are removed, the collagen fibers in the dermis layer are loosened, fixed and strengthened, and then a series of chemical and mechanical treatments such as finishing are carried out to turn the skin into leather.
  • Animal leather is mainly composed of fibrous components and non-fibrous components.
  • Fibrous components are mainly composed of collagen fibers, elastic fibers and mesh fibers.
  • Non-fibrous components are composed of blood vessels, sweat glands, fat glands, hair follicles, muscles, lymphatic vessels, nerves, and fibers. Qualitative and fat cells.
  • the weaving of the collagen fiber bundles in the mesh layer can be divided into three types, namely diamond, curved and wavy.
  • the characteristic of the diamond-shaped weave is that the collagen fiber bundle is thick and straight, and is cross-woven at a large angle to form a diamond shape. The more developed the mesh layer, the more obvious this type of weave characteristic.
  • the characteristic of the curved braid is that the collagen fiber bundles are thin and curved, interwoven with each other parallel to the surface of the animal leather, forming loops, branches or other various shapes.
  • the corrugated weave is characterized by thin and loose collagen fiber bundles, which are cross-woven parallel to the surface of animal leather.
  • the elastic fibers in animal leather are like steel bars in buildings, which fix other tissues in animal leather: hair follicles, sweat glands, fat glands, blood vessels, etc. in a certain position, thus playing a supporting and skeleton role in animal leather.
  • Reticulated fibers are composed of reticulated proteins. In terms of shape, reticulated fibers are not bundled like collagen fibers, but are branched and united. In nature, they are similar to collagen fibers. Reticulated fibers form a dense omentum, and Surrounding the surface of the collagen fiber bundle, a loose mesh cover is formed to protect the fiber bundle. In the leather making process, the mesh fiber plays a certain role in restricting the loosening of the collagen fiber bundle.
  • the animal leather fiber structure and cell tissue are filled with a colloidal substance, which is mainly composed of albumin, globulin, mucin and mucin-like substances and carbohydrate substances.
  • This colloidal substance is called fibrous interstitium. They infiltrate between collagen fibers for lubrication.
  • the interstitial fibers will solidify and harden, so that the fiber structure in the animal leather will stick tightly, so the animal leather becomes abnormally hard.
  • it is very important to remove the fibrous interstitium in the skin so as to ensure the looseness of the fiber structure and the penetration of chemical agents.
  • due to the special structure of animal leather it is difficult to completely remove the fibrous interstitium.
  • fattening is usually added to the animal leather
  • the fatliquor acts as a lubricant through the fatliquor. Once the animal leather added with the fatliquor is washed with water, the fatliquor will be lost, causing the hide to harden. Therefore, the animal leather is not suitable for washing.
  • Fur refers to products with use value obtained by tanning and dyeing and finishing animal skins with hair. Also known as fur.
  • the fur is composed of two parts, a fur coat and a leather board, and its value is mainly determined by the fur coat.
  • the skin of the fur is flexible, the coat is loose, bright, beautiful, warm, and durable. It is used to make clothing, shawls, hats, collars, gloves, cushions, tapestries and toys.
  • the fur in the fur grows out of the hair follicle, and there is no nesting structure between the hair and the animal leather forming a "V" or "W".
  • V or "W"
  • artificial fur is similar to the plush fabric of animal fur. Artificial fur is commonly used in coats, clothing linings, hats, collars, toys, mattress pads, interior decorations and carpets.
  • the manufacturing methods of artificial fur include knitting and weaving, etc.
  • the knitting weft knitting method has the fastest development and the widest application.
  • the carding mechanism disperses the tops into single fibers, and the knitting needle grabs the fibers and sets them into the base yarn for weaving.
  • the fluff is in the form of "V” or "W” in the loop, it has the knitted base fabric to shape and does not cause hair loss Characteristics. Due to the formation of fluff, the fluff tissue fabric is thick, soft and warm, and is suitable for making winter warm clothing.
  • the new generation of artificial fur surface layer is made of wool or wool and polyester fiber, viscose and other blends.
  • the ordinary combustion method is difficult to distinguish between artificial and natural, because there is no sintering phenomenon after burning, and they are all burned. Wool-flavored powder.
  • the base yarn uses natural fibers and / or synthetic fibers
  • the fleece uses synthetic fibers, in which acrylonitrile and modified acrylonitrile are used.
  • the fiber is mainly used, of course, animal hair such as wool, mohair or alpaca can also be used as down.
  • the structure is as follows: synthetic fiber or animal hair is inserted into the base yarn to form a loop together with the base yarn, and the finishing end of the synthetic fiber or animal hair protrudes from the surface of the knitted fabric to form a pile shape.
