  • Surface-processed fiber, method for manufacturing same, thread, and fiber product
    Patent number: 11814782
    Abstract: A protein surface layer is formed on a surface of a base fiber comprising a natural protein fiber including silk or a synthetic protein fiber including Chinon. The protein surface layer is divided in a plurality of particles by cracks. The resultant fibers with the protein surface layer divided in particles by cracks affords bulky textile products with an improved texture.
    Type: Grant

  • 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.

  • 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.
