摘　　要：对非光敏变色高日晒组合丽华实CA的高温加碱染色工艺以及低温预加碱染色工艺进行了探讨,并对丽华实CA浴比依存性、移染性进行测试。结果表明,丽华实CA对浴比依存性大,移染性较差,对元明粉及纯碱均较敏感,在生产时要控制元明粉及纯碱加入速度;采用低温预加碱工艺,能使染料均匀地上染到纤维上,减少色花的产生;但对于较厚的布种,适合采用高温加碱,否则易造成条花及表面染色异常。The dyeing processes with alkali application under high temperature and adding alkali in advance un-der low temperature of high sunlight-fastness and non-photosentive levafix CA were discussed, and liquor ratio de-pendency and migration ability of levafix CA was tested. The results show that liquor ratio dependency of levafix CA is big; the migration ability is poor, and it is sensitive to sodium sulfate and sodium carbonate, and the speed of adding sodium sulfate and sodium carbonate in production should be controlled; the fiber can be dyed uniformly and the phenomenon of dyeing defect reduces in dyeing processes with alkali application under low temperature;but for the thick fabric, the dyeing processes which adding alkali under high temperature is suitable, otherwise it is to cause barring and abnormal surface dyeing results.
