Method prepares collagen-based materials from sizing material

摘要

The collagen-based materials are the sizing materials by expansion generation by acid or alkaline organic or inorganic matter. This partly expands sizing material and decomposes with being mechanically and chemically, while alkalinity or acid organic or inorganic substance is added, so that at least 20% volume size millimeter is 2 to 6 with resulting pH value from 3 to 7. It is creation by swelling and disintegrating sizing material collagen-based materials, these can use water, if necessary. Then, collagen-based materials are handled through thermal denaturation, dehydration and separation fiber.
