Abstract: A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamino 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.

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. An inorganic salt is added to the solution, and a mole ratio of moisture to the inorganic salt in the solution is 2.5×m×n or less, where m represents the number of cations forming the inorganic salt and n represents a charge number of the cation. A production method of the present invention is a method for producing the above solution, including: changing at, least one of a moisture content and a content of the inorganic salt in the solution to adjust a viscosity of the solution. Thus, the present invention provides a polar solvent solution whose viscosity can be easily adjusted to a desired value and thus enables stable spinning and casting when used as dopes for spinning, film, etc., and methods for producing the same.

Abstract: In a garment production management apparatus, a garment information acquisition part acquires garment information to specify a garment an orderer has selected. A body shape information acquisition part acquires body shape information of a wearer who wears the garment. A production information acquisition part acquires the production information of the garment on the basis of the garment information and the body shape information. A production information output part outputs the production information to a seamless knitting machine. Here, the production information acquisition part may select production information from among a plurality of different pieces of production information associated with the garment information or modify the production information that serves as a base of the garment associated with the garment information on the basis of the body shape information.
