IMPROVEMENT OF DYE-ABSORBING PROPERTY OF CELLULOSE FIBER PRODUCT

摘要

PURPOSE:To improve dye-absorbency of cellulose fiber by treating with aqueous solution of sulfuric acid having specific concentration. CONSTITUTION:Cellulose fiber is dipped in an aqueous solution of sulfuric acid having 48-50 deg. Be at normal temperature for 20-60sec to vary molecular ordering in the fiber, reduce crystalline region and increase non-crystalline region in the fiber to improve dyeabsorbency of cellulose fiber without losing feeling of said fiber.
