Abstract

A basic leather fibre cloth is proportionally prepared from the leather fibres and other spinnable fibres through mixing and interlacing to form a stereo netted structure.

Description

A kind of preparation method of leather fibre based cloth

Technical field

The present invention relates to a kind of leather base fabric, be meant the preparation method who utilizes leather machine to open a kind of leather fibre based cloth of making behind the fibre especially.

Background technology

Human utilization to Animal Skin mainly is that the animal raw hide is processed into leather, be used for making clothes, shoes and hats, furniture, stomacher, automobile decoration material etc. then, the use of this leather requires very high to the selection of animal raw hide, both required size, require thin and thick even again, the every bit defective of leather as: scald note, fertile wrinkle, cut thorn, scratch, lice stings wound etc., all can make product become substandard products and waste product, by raw hide to leather, again by leather to finished product, the raw hide utilization rate of final animal has only 20~40%, and most of Animal Skin has become defect ware and tailing.

The home and abroad have with tailing and waste and old leather processing powdering, be mixed and made into regenerative leather or make nonwoven fabric with other flour again, but product specification is low with other mixed with fibers, of poor quality, consumption is few, makes a large amount of natural animal skin resource serious waste.

The present inventor is through the years of researches exploitation, patent application (the number of patent application: 200420083665.5 applyings date: on September 6th, 2004) of the fiber-opening apparatus of a kind of Animal Skin and leather has been proposed, the leather fiber that utilizes this fiber-opening apparatus to obtain has good processing characteristics, on this basis, utilize leather fiber to develop a kind of new dermatine base cloth.

Summary of the invention

The object of the present invention is to provide a kind of leather utilization rate height, use the preparation method of wide a kind of leather fibre based cloth.

The object of the present invention is achieved like this: a kind of preparation method of leather fibre based cloth, wherein: this base cloth opens fine leather fiber by 1~100% weight portion machinery and other textile fabric of 0~99% weight portion is formed, leather fiber each other, textile fabric reaches each other between leather fiber and the textile fabric that interting mutually interweaves forms solid netted braided structure, the length of leather fiber is 20~45mm, fineness 0.3D~2.5D; The length of textile fabric is 5mm~51mm, and fineness is 0.3D~7D.

Leather fiber described in the above-mentioned leather fibre based cloth is to adopt at least a in the animal's leather fibers such as ox, horse, mule, donkey, camel, deer, sheep, pig, dog, wolf, rabbit, mouse, kangaroo, crocodile, fish and snake.

Textile fabric described in the above-mentioned leather fibre based cloth can be long fiber, it also can be staple fibre, both can be natural textile fiber as cotton, fiber crops, silk, bamboo, Cashmere and Woolens, camel's hair camel hair, the rabbit suede rabbit hair, dog suede dog hair, Down and Feather etc., also can be at least a in chemical fibre such as terylene, acrylic fibers, spandex, polyamide fibre, polypropylene fibre etc. or artificial fibre such as viscose glue, day silk, soybean, milk, the crust fat etc.

Above-mentioned leather fibre based cloth also is provided with the netted base fabric of one deck at least.

After the present invention adopts said structure, can make full use of the different performance of various fibers, form miscellaneous leather base fabric kind, comprehensively provide a broad-spectrum new way for animal's leather.And the back processed of this base cloth is also very convenient, can utilize the processing and treating method of prior art to base cloth, forms the various uses new product.And the tailing resource of animal's leather is also very abundant, can also utilize the waste and old leather that exists a large amount of prices cheaper in the society.
