摘　　要：采用银杏叶染料对阳离子改性棉织物进行染色,分析了染料质量分数、染色温度、时间以及染液p H值对染色织物K/S值的影响。结果表明,影响染色效果的显著程度为:银杏叶染料质量分数>染液p H值>染色温度>染色时间。较合适的染色工艺条件为染色温度80℃,染液p H值6,染色时间50 min,染料10%(omf)。该工艺条件下染色棉织物的K/S值为4.61,耐洗色牢度为3~4级,干摩擦色牢度为3~4级,湿摩擦色牢度为3级,UPF值100+,透射率<5%,具有较好的防紫外线效果。The cationic modified cotton fabric is dyed by ginkgo leaf dye. The factors of dye concentra- tion, dyeing temperature, dyeing time and pH value on K/S value are studied. The results show that the significance is the concentration of ginkgo leaf dye 〉 the pH value of dye solution 〉 dyeing tempera- ture 〉 dyeing time. The optimal dyeing conditions are dyeing temperature 80 ℃, pH value 6, dyeing time 50 min, dye concentration 10%（omf）. Under the above conditions, the K/S value of dyed cotton fabric is 4.61, the washing fastness is Grade 3-4, the dry rubbing fastness is Grade 3-4, the wet rubbing fast- ness is Grade 3. And the dyeings have good anti-UV effect with the UPF value of 100＋ and the transmit- tance ratio less than 5%.
