In order to probe the possibility of utilizing chromed leather wastes from the view of textile, firstly ultra-short leather fiber of 0.01～0.5cm 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.
