DYEABLE CROSSLINKED ACRYLATE FIBER, PROCESS FOR PRODUCING THE SAME, AND DYED CROSSLINKED ACRYLATE FIBER OBTAINED BY DYEING THE FIBER

摘要

A crosslinked acrylate fiber which is excellent in the property of being evenly and densely dyed, can have high color fastness, and even after dyeing, can have the same properties including moisture-absorbing/releasing properties, antibacterial properties, and deodorizing properties as before dyeing. The dyeable crosslinked acrylate fiber is characterized by being obtained by subjecting an acrylic fiber to a treatment with a hydrazine compound and a treatment with an aminated organic compound having two or more primary amino groups per molecule and then hydrolyzing the fiber.
