摘要
为研究紫甘薯色素在蚕丝面料染色及功能整理中的应用,以质量分数20%的乙醇溶液为提取溶剂,通过设计正交试验得到紫甘薯色素超声辅助提取较优工艺条件为:料液比1∶5,超声功率200 W,40℃下超声30 min。在此基础上用紫甘薯色素直接上染蚕丝面料,在染液质量浓度为16 g/L,pH=3,染色温度70℃条件下染色75 min得到的染色K/S值和色牢度相对较好。以硫酸铜、硫酸亚铁和硫酸铝钾为媒染剂,采用后媒染色工艺上染,紫甘薯色素的染色效果明显提升。同时,蚕丝面料因上染紫甘薯色素也展示出了一定的抑菌、抗氧化及防紫外效果。
In order to study the application of purple sweet potato pigment in silk dyeing and functional finishing,using ethanol solution(20 wt%)as the extraction solvent,the optimum ultrasonic assisted extraction conditions of purple sweet potato pigments are obtained through orthogonal experiments as follows:the solid-liquid ratio 1∶5,the ultrasonic power 200 W,and ultrasonic conducting at 40℃for30 min.On this basis,the silk fabric is directly dyed with purple sweet potato pigments under conditions of dye concentration of 16 g/L,p H value of 3,and dyeing at 70℃for 75 min,and the K/S value and color fastness of the silk dyeing are relatively good.Copper sulfate,ferrous sulfate and potassium aluminum sulfate are used as the mordant,the dyeing effect of purple sweet potato pigments with post mordant dyeing could be improved obviously.At the same time,the silk dyeings with purple sweet potato pigment also show certain antibacterial,antioxidant and UV protective effects.
