Abstract
An acrylic fiber has 99.9 to 85 mol % of acrylonitrile units, and 0.1 to 15 mol % of N-vinylcarboxylic acid amide units, wherein the latter unit may be modified. The fiber is excellent, e.g., in dyeing property and hygroscopicity, and can be readily converted into a functional fiber.
Claims5
