  • Nonwoven Fabric, and Method for Producing Same
    Publication number: 20230212798
    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.

  • Protein Spun Yarn Manufacturing Method
    Publication number: 20210388537
    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.

  • Blended Yarn, Knitted/Woven Body of Same, and Method for Manufacturing Said Knitted/Woven Body
    Publication number: 20210032782
    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.

  • PROTEIN FIBER CRIMPING METHOD, PROTEIN FIBER PRODUCTION METHOD, PROTEIN FIBERS, SPUN YARN, AND TEXTILE PRODUCT
    Publication number: 20210017672
    Abstract: Protein fiber having 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. The protein having a different composition is infiltrated into the protein fiber and the protein fiber is made crimped.

  • Method for Recovering Protein
    Publication number: 20190352330
    Abstract: The present invention relates to a method for recovering protein, which recovers a target protein from a mixture containing the target protein and a material different from the target protein, the method including a dissolution step of dissolving either the target protein or the material by applying pressure while heating to a solution for dissolution containing the mixture and a polar solvent, and a separation step of separating an obtained solution.
