PURPOSE:To obtain the solidified material of silk which holds the intrinsic properties of silk by mixing a vinyl-based monomer with silk powder at a specified rate and using this mixture, heating and compressing the same in a mold, for example, at the specified temperature and pressure. CONSTITUTION:A vinyl-based monomer is mixed with silk powder and this mixed powder is pressurized and heated. For example, the mixed powder is pressurized and molded at ordinary temperature at >=100kg/cm<2> and thereafter the molded form is heated at <=200 deg.C in an electric furnace or the like. The blending amount of both the vinyl-based monomer and silk powder is not especially limited. The vinyl-based monomer is preferably used at amount of 5-100 pts.wt. for 100 pts.wt. silk powder. When the blending amount of the vinyl-based monomer exceeds 100 pts.wt., the silky touch of the obtained moldings is decreased. There is a tendency so that water absorption property and moisture release properties of silk are deteriorated. Further there is the tendency so that workability is deteriorated in the amount less than 5 pts.wt. In this method, the solidified material of silk is obtained which is excellent in water resistance, workability and mechanical strength or the like and also holds the intrinsic properties of silk. |
