Abstract
An acrylonitrile-containing fiber includes 100 parts by mass of a polymer including at least 15 parts by mass of acrylonitrile; and 1.0 to 50 parts by mass of a water absorbent resin having a pure water absorption capacity (gig) with respect to its own weight of at least 10 but less than 100, wherein the fiber is dyeable with a disperse dye.
Claims20
An acrylonitrile-containing fiber, comprising:
- 100 parts by mass of a polymer comprising at least 15 parts by mass of acrylonitrile;
- and
- 1.0 to 50 parts by mass of a water absorbent resin having a pure water absorption capacity (g/g) with respect to its own weight of at least 10 but less than 100,
- wherein the fiber is dyeable with a disperse dye.
A method for producing an acrylonitrile-containing fiber, the method comprising:
- preparing a spinning solution by dissolving, in an organic solvent, 100 parts by mass of a polymer comprising at least 15 parts by mass of acrylonitrile and 1.0 to 50 parts by mass of a water absorbent resin having a pure water absorption capacity (g/g) with respect to its own weight of at least 10 but less than 100;
- and
- spinning the spinning solution to obtain an acrylonitrile-containing fiber, wherein the acrylonitrile-containing fiber is dyeable with a disperse dye.
A fiber product comprising an acrylonitrile-containing fiber, wherein the acrylonitrile-containing fiber comprises:
- 100 parts by mass of a polymer comprising at least 15 parts by mass of acrylonitrile;
- and
- 1.0 to 50 parts by mass of a water absorbent resin having a pure water absorption capacity (g′g) with respect to its own weight of at least 10 but less than 100,
- wherein the acrylonitrile-containing fiber is dyeable with a disperse dye.
