The Physical Properties of Ultra-short Leather Fiber Extracted from Chromed Leather Waste and Its Use in Textile Industry

In order to probe the possibility of utilizing chromed leather wastes from the view of textile, firstly ultra-short leather fiber of 0.01 similar to 0.5cm was extracted by special equipment. Then the fiber structure was characterized; the moisture absorbency was tested and compared with wool and silk protein fibers. On the above basis, ultra-short collagen fiber suede fabric was developed successfully. The results indicate that ultra-short collagen fibers exist in bundles, adhesion forces between fibers are larger those of single (bundle) fiber strength. Their moisture absorbency is similar to that of wool. The micro-suede fabric made is suitable for decorating materials.
