Problems solved by technology

[0005] One of the objectives of the present invention is to solve the problem of low utilization rate of animal skins, especially animal residual skins or leather leftovers in the prior art, as well as the problem of recycling and recycling waste leather, and provide a method for separating animal skins by mechanical fiber opening. The fibrous bundles of collagen fibers are processed into monofilament animal skin fibers, and then the animal skin fibers are spun into a kind of animal skin yarn for weaving.

Embodiment 1

[0038] Embodiment 1: the production of kraft fiber

[0039] Sorting: Screening and sorting cowhide leather of different weights, thicknesses, and sizes, leftovers or recycled waste cowhide.

[0040] Swelling: Put the sorted cowhide into an aqueous solution with a liquid ratio of 500%, Remibang A2%, high-efficiency wetting agent 1.5%, and a temperature of 28-30°C, stir evenly, soak for 18 hours, wash with water, dehydrate, and cool. Dry.

[0041] Fiber opening: Use a self-made fiber opening machine for fiber opening, and process the swollen cowhide leather into cowhide fibers with a thickness of 15-45mm and a fineness of 1D-2.3D.

[0042] Degumming: Put the opened kraft fiber into the degreased aqueous solution (PH value 7.5-9.0) with 5% anionic nonionic surfactant and 6% organic solvent added by weight, stir evenly at room temperature, and soak for 60 minutes , Wash with water, shake dry.

[0043] Decolorization: put the degummed kraft fiber into an aqueous solution added w...

Embodiment 2

[0046] Embodiment 2: the production of pigskin fiber

[0047] Swelling: put the sorted pigskin into an aqueous solution with a liquid ratio of 550%, Remybang A1.8%, high-efficiency wetting agent 1.3%, and a temperature of 28-30°C, stir evenly, soak for 16 hours, wash with water, and dehydrate , dry.

[0048] Fiber opening: Use a self-made fiber opening machine for fiber opening, and process the swollen pigskin leather into pigskin fibers with a thickness of 10-40mm and a fineness of 0.8D-2D.

[0049] Degumming: Put the loosened pigskin fiber into the degreasing aqueous solution (PH value 6.0-8.0) added with 5% by weight surfactant and 5% organic solvent, stir evenly at room temperature, soak for 45 minutes, wash with water , shake dry.

[0050] Decolorization: put the degummed pigskin fibers into an aqueous solution added with 5% by weight bleaching water at a temperature of 35-37° C., soak for 30 minutes, wash with water, and dry with hot air.

[0051] Other sorting, impur...

Embodiment 3

[0052] Embodiment 3: the production of goatskin fiber

[0053] Swelling: put the sorted goatskin into an aqueous solution with a liquid ratio of 600%, Remibang A1.5%, high-efficiency wetting agent 1%, and a temperature of 28-30°C, stir evenly, soak for 15 hours, wash with water, Dehydrate and dry.

[0054] Fiber opening: Use a self-made fiber opening machine for fiber opening, and process the swollen goatskin leather into goatskin fibers with a thickness of 16-30mm and a fineness of 0.3D-1D.

[0055] Degumming: Put the loosened goatskin fiber into the normal temperature aqueous solution (pH value 7.0-8.0) added with 10% by weight of AD leather degreasing agent, stir evenly, soak for 20 minutes, wash with water, and spin dry.

[0056] Decolorization: put the degummed goatskin fibers into an aqueous solution added with 5% by weight bleaching water at a temperature of 25-30° C., stir evenly for 30 minutes, wash with water, and dry with hot air.

Abstract

The animal leather yarn consists of mechanically opened animal leather fiber in 1-100 wt% and other textile fiber in 0-99 wt%, and the animal leather fiber and other textile fiber in the same weight ratio are crossed and twisted to form the animal leather yarn. Leather processed through traditional leather processing process is further processed through sorting, swelling, opening, deguming, decolorizing, impurity eliminating, grading, mixing, finishing, carding into sliver, twisting and spinning to produce the animal leather yarn. The present invention raises the utilization of leather, expands leather application and, especially, solves the problem of waste leather utilization.

Description

technical field [0001] The invention relates to a textile yarn and its production technology, in particular to a yarn made from animal skin fibers and a production method thereof. Background technique [0002] There are many types and varieties of animals on the earth, and animal skin resources are very rich. Animal skin is mainly composed of collagen fibers. The fibers are interwoven and tightly intertwined in a bundle, and each bundle of collagen fibers is composed of many fine collagen fibers. Animal skin is divided into epidermis, dermis and subcutaneous tissue. Among them, the dermis accounts for more than 90%, and the dermis is composed of the papillary layer and the reticular layer. The collagen fibers in the papillary layer are loosely woven, and the collagen fibers in the reticular layer are tightly woven. The collagen fibers account for more than 95% of the fibers of the entire skin plate. And in the form of fiber bundles, they criss-cross in the dermis, cross e...
