摘　　要：使用粘质沙雷氏菌发酵制备了灵菌红素,并通过在培养液中添加吐温80制备了色素纳米胶束分散液。对制得分散液中胶束粒径进行了表征,将制备的分散液用于棉针织物、羊毛针织物、涤纶针织物的染色,对染色后织物的性能进行了测试。结果表明:制备的灵菌红素胶束分散液平均粒径为253.8 nm;当染液中乙醇用量为25.0%时,染色棉针织物颜色最深;当染色温度为90℃时,染色羊毛针织物颜色最深;涤纶织物染色最优温度为110℃;染色后的织物色泽鲜艳,具有良好的耐摩擦、耐皂洗、耐汗渍色牢度,同时染色后织物对金黄色葡萄球菌有较好的抑菌效果。Prodigiosins were produced by the fermentation of Serratiamarcescens and the nanosuspension of prodigiosins micelles was obtained through adding nonionic surfactant to the cultivating media. The particle size of prodigioins micelles was characterized. Furthermore, the prodigiosinsnanomicelles was used to dye cotton, wool and polyester fabrics, respectively, and the property of dyed fabrics was tested. The results indicated that the average particle size of the prodigioins micelleswas 253.8 nm. When the ethanol concentration of dye bath was 25.0%, dyed cotton fabric exhibited the highest color fastness. When the dyeing temperature was set at 90 ℃, dyed wool fabric possessed the maximum K/S value. The optimum dyeing temperature of polyester fabric was 110 ℃.All dyed fabrics were colorful and possessed good rubbing, washing and perspiration color fastness, which could meet the wearing requirements. Besides, the dyed fabrics exhibited good antibacterial properties against staphylococcus aureus.
