Embodiment 1
[0029] Embodiment one, select untanned animal gray skin and leftover material thereof for use. In parts by weight, take 80%-99% of collagen fiber bundles; 1%-20% of chemical textile fibers, 1-5% of interstitial fibers; a small or trace amount of elastic fibers, reticular fibers, sweat glands, lipids in raw hides Glands, blood vessels, and other non-fibrous substances and a small amount of non-fibrous substances artificially added in the pre-tanning process are ignored.
[0030] Technological process: raw material screening - impregnation - hair removal - degreasing - liquid defibrillation - tanning - dehydration and drying - mixing - adding fiber matrix - health - opening - carding - paving Net - stabbed - hot rolled.
[0031] Process description:
[0032] 1. Raw material screening: select at least one animal skin from cattle, sheep, pigs, horses, dogs, deer, rabbits, crocodiles and snakes or untanned gray leather corners.
[0033] 2. Dipping: Dipping in the liquid for 1 to...
Embodiment 2
[0048] Embodiment two, by weight, collagen fiber bundle 30%~80%; Cotton, fiber crops, wool, silk natural textile fiber 20~70%, fiber interstitial 3~10%; Inherent trace elastic fiber in the original leather , reticulated fibers and other non-fibrous substances and artificially added non-fibrous substances in the tanning process are ignored.
[0049] Technological process: raw material screening - impregnation - liquid defibrillation - dehydration and drying - mixing - adding fiber matrix - health care - opening - carding - net laying - stabbing - hot rolling .
[0050] The technological process of this embodiment is different from embodiment one in that:
[0051] 1. Raw material screening: select all kinds of leather tanned by tanning process and its leftover materials and waste leather.
[0052] 2. Immerse in a liquid at 15°C to 60°C for more than 10 hours, and the rest of the process is the same as Example 1.
Embodiment 3
[0053] Embodiment three, by weight, collagen fiber bundle 90~99%, fibrous interstitium 1~10%; Inherent micro elastic fiber, reticular fiber and other non-fibrous substances and other residues in the original leather and the tanning process Artificially added non-fibrous matter is ignored.
[0054] The process flow and process description of this embodiment are the same as those of Embodiment 2, and will not be repeated here.
