摘　　要：采用自制紫外线吸收剂UVX,与酸性翠蓝对锦纶同浴染色,对相关因素进行正交试验和相关色牢度测试。结果表明,锦纶翠蓝染样的耐光色牢度能提高0.5～1级,同时对耐摩擦色牢度和耐洗色牢度没有影响。优化的工艺条件为:pH值4、浴比1∶20、升温速率为1.0℃/min、染色温度95℃、时间30min。One bath dyeing with ultra violet absorber UVX and acid turquoise blue was studied. Orthogonal experiment was carried out and relative fastness were tested. As a result, the color fastness to light of nylon dyed by acid turquoise blue improved 0.5 - 1 grade , the color fastness to washing and rubbing were not influenced at the same time. The optimal process is pH value 4, liquor ratio 1 ： 20, heating speed 1.0 ℃/min, dyeing at 95 ℃ for 30 min.
