摘　　要：以天然植物染料栀子黄为原料,通过正交试验及单因素分析确定了栀子黄染料对棉针织物直接染色的最佳工艺条件为:温度95℃、染料用量5%(o.w.f)、pH值5;探讨了同媒染、中性电解质、表面活性剂对染色效果的影响,并测试织物对大肠杆菌的抗菌性能.实验表明:同媒染、中性电解质、表面活性剂对颜色特征的影响很小,栀子黄染色棉针织物具有良好的色牢度,符合国家标准;栀子黄染料染色的棉针织物对大肠杆菌的抑菌率达到75%以上,完全符合国家标准,具有良好的抗菌作用,表明栀子黄染色可以赋予织物良好的抗菌性.With natural vegetable of gardenia yellow dyeing as raw material, through orthogonal experiments and single fac-tor analysis, the optimum conditions of gardenia yellow dyeing on cotton knitted fabric are determined. The dye-ing temperature is 95 ℃ , the amount of dye is 5% （o.w.f）, pH value is 5. The effects of the mordant, neutralelectrolyte, surface active agent on dyeing effect are analyzed, and the fabric antimicrobial activities against Es-cherichia coli are tested. Experiments show that the impact of mordant, neutral electrolyte, surface active agents on the color characteristics is very small. The gardenia yellow dyeing of cotton knitted fabric has good color fast-ness, which is in accordance with national standards. Finally, the antibacterial rate of the cotton knitted fabric dyed by gardenia yellow dye is above 75%, which is in line with national standards and has a good antibacterial effect. It is indicated that gardenia yellow dyeing could endow the fabric with good antimicrobial activity.
