Abstract: The present invention aims at providing a blended yarn with which a knitted or woven body, wherein a decrease in tension and stiffness due to moistness is reduced, can be manufactured, even in a case where the blended yarn is used for the manufacture of the knitted or woven body; a knitted or woven body of the same; and a method for manufacturing the knitted or woven body. The blended yarn according to the present invention comprises a modified fibroin fiber and a regenerated cellulose fiber.

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.

Abstract: A protein fiber having a crimp property, such that the protein fiber crimps in response to a stimulus, is immersed in a solution of protein having a different composition from the protein fiber. The protein fiber treated with the different protein composition is infiltrated into the protein and the protein fiber is made to crimp.

Abstract: An object of the present invention is to provide a nonwoven fabric that makes it difficult to diffuse liquid in a plane direction and can absorb and transmit liquid in a spot manner, that is, a nonwoven fabric excellent in so-called spot absorbability. The nonwoven fabric according to the present invention is formed by mixing an artificial protein fiber and a hydrophobic synthetic fiber.
