Abstract
The present disclosure relates to a method for manufacturing a molded article with improved molding ability of fibroin, wherein the process comprises placing a powder containing a fibroin and a compound having two or more functional groups of a guanidyl group or an amino group and having carbon chains of three to six carbons between the functional groups into a mold, and compressing the powder in the mold with a piston.
Claims7
A method for manufacturing a molded article comprising:
- placing a powder containing a fibroin and a compound having two or more functional groups of a guanidyl group or an amino group and having carbon chains of three to six carbons between the functional groups into a mold, and
- compressing the powder in the mold with a piston;
- wherein, the amount of the compound in the powder is 1% by weight or more and 10% by weight or less relative to the powder and the presence of the compound in the powder increases the fluidity of the fibroin.
A method for manufacturing a molded article comprising:
- preparing a powder containing a fibroin and a compound having two or more functional groups of a guanidyl group or an amino group and having carbon chains of three to six carbons between the functional groups by:
- obtaining an aqueous solution in which the fibroin is dissolved, wherein the fibroin concentration in the aqueous solution obtained in the obtaining is 2 parts by weight or more and 30 parts by weight or less relative to water;
- mixing the compound into the aqueous solution, and
- removing water as a solvent from the aqueous solution obtained by the mixing;
- placing the powder into a mold, and
- compressing the powder in the mold with a piston.
