Title:
収縮性吸湿アクリロニトリル系繊維、該繊維の製造方法および該繊維を含有する繊維構造体
Document Type and Number:
Japanese Patent JP7177986
Kind Code:
B2
Abstract:
To provide a shrinkable moisture absorption acrylonitrile-based fiber capable of being produced with simple processes, for overcoming situation that shrinkable acrylic fiber is known conventionally, but it has no moisture absorption property and a problem in comfortableness, a crosslinked acrylate-based fiber has no shrinkability and low productivity even though it is excellent in moisture absorption property, and further enhancing moisture absorption property of an acrylic fiber containing acrylic acid as a copolymer component is difficult.SOLUTION: There is provided a shrinkable moisture absorption acrylonitrile-based fiber constituted by a polymer having practically no crosslinking structure by a covalent bond, containing 0.2 to 4.5 mmol/g of carboxyl group in the fiber, having saturation moisture absorption rate at 20°C×65% RH of 3 wt.% or more, boiling water shrinkage rate of 5 to 50%, and water swelling degree of 10 times or less.SELECTED DRAWING: None
