Abstract
An object of the present invention is to provide a method for producing protein spinning capable of securing a stable strength by securing sufficient interlacing between fibers. The method for producing a protein spun yarn of the present invention includes a step (a) of preparing a raw material spun yarn including an uncrimped artificial fibroin fiber containing modified fibroin and a step (b) of bringing the raw material spun yarn into contact with an aqueous medium to crimp the artificial fibroin fiber.
