Spun laced fabric and processing method thereof

Abstract

The invention discloses spun-laced cloth and a method for manufacturing the spun-laced cloth. The spun-laced cloth is composed of collagen fiber bundles, other textile-used staple fibers and interstitial fibers, wherein the collagen fiber bundles are mutually interpenetrated and interweaved with branches of the collagen fiber bundles to form stereo reticular braided structures, other textile-used staple fibers are located on skeleton of the stereo reticular braided structures, reticular entwining is formed between the textile-used staple fibers mutually or between the textile-used staple fibers and the collagen fiber bundles and the branches of the collagen fiber bundles, and fiber is adhered or bound by the interstitial fibers. The method of the invention can take animal raw hide as raw materials and can be realized through following technical steps: screening the raw materials, dipping, unhairing, degreasing, defibering liquid, tanning, dewatering and drying, mixed liganding, adding the interstitial fibers, health preserving, opening, combing,laying net, spunlacing, and hot rolling, furthermore, the method of the invention can also take the animal leather after tanning as the raw material and can be realized through following steps: screening the raw materials, dipping, defibering the liquid, dewatering and drying, mixed liganding, adding the interstitial fibers, health preserving, opening, combing, laying net, spunlacing, and hot rolling.

Description

Technical field: [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a spunlace fabric and a processing method thereof. Background technique: [0002] At present, most of the traditional spunlace fabrics are made of chemical staple fibers such as viscose fiber, polyester fiber, nylon fiber or sea-island fiber (superfine fiber), and there are also a small amount of natural fabrics that use cotton, linen, wool, and silk staple fibers. The fibers are made into spunlace fabrics. Although the spunlace cloth has a wide range of uses, such as sanitary materials and synthetic leather base cloth, etc., because its fibers are all single loose short fibers, the fiber winding structure of the material obtained through spunlace processing is too simple, and chemical Or natural long fibers cannot be processed by spunlace technology, so the current various spunlace fabrics are far inferior to woven fabrics in terms of tensile strength, and can only be...

Problems solved by technology

[0010] The object of the present invention is to provide a kind of utilizing any animal skin or leather with different shapes, especially its leftover material, the collagen fiber bundle of natural weaving state is decomposed into loose collagen fiber bundle with spinnable length and then combined with other Textile short fibers are mixed to re-establish a three-dimensional network weaving structure in which collagen fiber bundles and their branches are interspersed with each other and crisscross, and other textile short fibers are netted together in the skeleton formed by collagen fiber bundles, and at the same time Using a small amount of fibrous interstitial, a natural protein material, the woven fibers are bonded or bonded together to form a tissue structure similar to that of the original animal leather, and have sufficient width, length and weaving of various parts like textiles A spunlace fabric and its processing method with consistent compactness, consistent thickness, and various strength indicators of woven fabrics, so as to give full play to the physical and chemical properties of other textile fibers, so as to solve the problem that the existing spunlace fabrics cannot directly Becoming a matter of durable materials, making the dream of "cloth in one step" a reality
