Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of regenerated cowhide fiber clothing fabric, belong to clothing fabric technical field. BACKGROUND

[0002] Animal leather is mainly composed of collagen fiber, and the fibers are closely combined together in sheet shape by interstitial substance, fat and non-fiber protein. At present, the use of animal skin is mainly to process into leather sheet, which is used to make leather shoes, clothing or leather products. This utilization method requires high quality animal leather, which must have certain size and uniform thickness. The utilization rate of animal leather is low, only 20-40%. Most of the leftover materials become waste. These leftover materials are usually prepared and broken to form collagen fiber, crosslinked fiber, resin and other additives. The process flow is as follows: the raw material of leather or regenerated leather is crushed into leather fiber of a certain size, then mixed with natural rubber, resin and other raw materials, and then compressed into filter cake. The filter cake is heated to melt the fibers on the surface and have viscosity. Each layer is extruded, bonded and dehydrated to form. After cooling, drying, slicing, embossing and surface treatment, the final regenerated leather is obtained. The collagen fiber in cowhide is made into leather fiber of 20-30mm length by physical and chemical methods for spinning and weaving. However, the length of regenerated cowhide fiber is short, the strength of the prepared yarn is low, and the regenerated cowhide fiber is easy to fall off. How to overcome the above problems and prepare a regenerated cowhide fiber clothing fabric has become a problem to be solved. SUMMARY
