  • Patent number: 11668024
    Abstract: A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamine acid is dissolved in a polar solvent. The solution has a moisture content of less than 5 mass % based on 100 mass % of the solution. A method for producing a polar solvent solution of the present invention includes changing a moisture content of the solution to adjust the viscosity of the solution. Further, another method for producing a polar solvent solution includes reducing a moisture content of the solution to increase the viscosity of the solution. Thus, the present invention provides a polar solvent solution that enables stable spinning and casting without lowering its viscosity when used as dopes for spinning, film, etc., and methods for producing the same.

  • Patent number: 9689089
    Abstract: A solution-dyed protein fiber of the present invention includes 0-100 mass % of silk fibroin and 100-0 mass % of a polypeptide derived from spider silk proteins when the protein fiber is assumed to be 100 mass %, wherein the solution-dyed protein fiber contains a solution-dyeing colorant. The fiber is obtained by: dissolving or dispersing a solution-dyeing colorant in a solvent used for a spinning solution or in dimethyl sulfoxide, thereby preparing a coloring liquid; adding a solvent to the coloring liquid in an amount necessary for a spinning solution; adding and dissolving protein powder into the solvent, thereby preparing a spinning solution; and subjecting the spinning solution to wet spinning or dry-wet spinning. Thereby, the present invention provides a low-cost solution-dyed protein fiber in which a solution-dyeing colorant is dispersed uniformly and that can exhibit bright color tone, and a method for producing the same.

  • Publication number: 20150355007
    Abstract: An apparatus, method and computer program product for analyzing fluidity are provided which enable fineness and coarseness in a particle distribution pattern in an object to be restrained in analysis results and thus, the fluidity analysis to be conducted with high accuracy. The apparatus for analyzing fluidity, using a particle method, determines a velocity of each particle, based on particle information of a position of each particle and a physical state of each particle in the last time step, and determines a position of each particle in the current time step, based on the velocity determined. The apparatus for analyzing fluidity next rearranges, based on distances between particles arranged at the determined positions, each particle in the current time step so that the fineness and coarseness in the particle distribution pattern in a target for analysis is reduced.

  • Patent number: 9051453
    Abstract: A polypeptide solution of the present invention is a polypeptide solution in which a polypeptide derived from natural spider silk proteins is dissolved in a solvent. The solvent contains at least one selected from the following (i)-(iii): (i) DMSO; (ii) DMSO with an inorganic salt; and (iii) DMF with an inorganic salt. Further, in the present invention, an artificial polypeptide fiber is obtained by: using the polypeptide solution as a dope solution; and extruding the dope solution from a spinneret into a desolvation bath so as to eliminate the solvent from the dope solution and form a fiber to produce an undrawn yarn. Moreover, in the present invention, a polypeptide is purified by subjecting the polypeptide solution to heat treatment and thereafter removing an undissolved substance therefrom.
