| 摘 要： | 探讨了染液pH值、酸性固色剂TF-506预处理、盐碱加入方式等因素对锦／棉织物双色效果的影响。结果表明，酸性／直接混纺染料-浴染锦／棉，若通过调节染液pH值，很难解决染料的得色和相互沾色的矛盾，双色效果不理想；若先经酸性固色剂TF-506预处理，再在弱酸性条件下染色，则可获得较好的效果。酸性／活性染料应采用两浴法染锦／棉，先棉染活性染料再锦纶染酸性染料。织物先经预处理或活性染料染色时，采用盐碱一步法代替传统的盐碱两步法，都可获得理想的效果，若采用后者应选择耐碱性和匀染性较好的活性染料。

| Abstract: | The influence of factors such as pH value of dyeing liquor, pretreatment with acid fixing agent TF-506, adding method of salt and alkali to two-color effect of polyamide-cotton fabric were discussed. As a result, in one-bath with acid/direct dyes, the pretreatment with acid fixing agent TF-506 prior to weak acid dyeing should be adopted. As for acid/reactive dyes, two-bath dyeing should be applied, first reactive dyes for cotton fiber and then acid dyes for polyamide fiber. At the same time, salt/alkali one-step method substituted conventional salt/alkali two-step method can also obtain the ideal two-color effect. |
