摘　　要：针对海藻纤维在含有钠离子的环境中染色容易发生凝胶化,进而溶解的加工难题,设计海藻纤维搭配易上色的阳离子粘胶纤维混纺针织面料。测定了混纺面料在酸性染料、无碱活性染料、直接染料无盐无碱环境下染色的色牢度、海藻纤维失重率指标,发现海藻纤维/阳离子混纺针织面料在酸性染料无盐无碱染色环境下生产,海藻纤维失重率小于5%,浅中色色牢度大于4级,顶破强力大于180 N。Aiming at the processing problem of gelatinization and dissolve of alginate fiber in the dyeing environment containing Na+,alginate fiber is designed to be knitted with the cationic viscose fiber.The color fastness and alginate fiber weightlessness rate of blended fabric using acid dye,reactive dye with⁃out alkali,direct dye without salt and alkali are tested.The results show that weightlessness rate of algi⁃nate fiber in the blended knitted fabric is less than 5%when using acid dye.The color fastness of fabric in light-to-medium shade is above Grade 4,bursting strength is above 180 N.
