An object of the present invention is to provide a method for producing a modified fibroin multifilament excellent in productivity and a multifilament produced by the same. The multifilament of the present invention contains modified fibroin, in which the multifilament has 100 or more constituent single yarns, a coefficient of variation in elastic modulus is 15% or less, a coefficient of variation in strength is 15% or less, and a coefficient of variation in elongation is less than 33%.
A multifilament comprising modified fibroin, wherein the multifilament has 100 or more constituent single yarns, a coefficient of variation in elastic modulus is 15% or less, a coefficient of variation in strength is 15% or less, and a coefficient of variation in elongation is less than 33%.
A multifilament comprising a recombinant structural protein, wherein the multifilament has 100 or more constituent single yarns, and a coefficient of variation in elongation is less than 33%.
A method for producing a multifilament, comprising a step of discharging a spinning raw material solution containing modified fibroin and a solvent from a spinning nozzle having 100 or more holes, and bringing the spinning raw material solution into contact with a coagulation liquid to coagulate the modified fibroin.
