Abstract:
     A process for extracting collagen fibres includes such steps as immersing animal tissue in high-penetrability acid, washing to remove acid, enzymolyzing and grinding. A process for preparing tissue filler includes such steps as diluting said collagen fibres, packing, sealing and sterilizing to obtain the filler for soft tissue, or die pressing said collagen fibres, drying and sterilizing to obtain the filler for hard dissue. Its advantages are high output rate up to more than 80% and quality, and long storage period.
