FLUORESCENT WHITENED HIGHLY CROSS-LINKED POLYACRYLATE FIBER, MANUFACTURING METHOD THEREFOR, AND FIBER STRUCTURE COMPRISING SAME

WIPO Patent Application WO/2014/162898

A1

For this fluorescent whitened highly cross-linked polyacrylate fiber, an anionic fluorescent whitener is adhered to a highly cross-linked polyacrylate fiber, which adsorbs gas phase moisture and generates heat. Said fluorescent whitened highly cross-linked polyacrylate fiber is obtained by bringing a highly cross-linked polyacrylate fiber, which adsorbs gas phase moisture and generates heat, into contact with an aqueous dispersion containing an anionic fluorescent whitener and treating for 20 seconds - 120 minutes at 10-200°C. This fiber structure comprises said fluorescent whitened highly cross-linked polyacrylate fiber. Provided thereby are: a highly cross-linked polyacrylate fiber in which red is reduced and whiteness increased, and the amount of heat generated and the amount of moisture adsorbed when gas phase moisture is adsorbed have been further improved; and a fiber structure comprising same.
