涤纶织物的黄芩染色

Dyeing of Scutellaria Baicalensis Georgi on polyester fabric

为开发具有保健作用的新型天然染料,选用黄芩提取色素对涤纶织物进行高温高压染色.通过单因素试验和正交试验研究了提取液用量、染色温度、染色保温时间、pH值对涤纶织物染色性能的影响.结果表明,黄芩通过高温高压染色法在涤纶织物上得到棕色,优化工艺为：温度130℃,pH值5,提取液用量50％,时间60 min.染色涤纶的耐水洗牢度和耐摩擦牢度很好,能达到4～5级;耐日晒牢度较差,仅为1～2级,有很强的抗紫外线性和一定的抗菌性.

In order to develop new natural dyes with health care function,Scutellaria Baicalensis Georgi extract pigment was selected for high temperature and high pressure dyeing on polyester fabric to study the application and functional embodiment of Scutellaria Baicalensis Georgi on polyester fabric.And influences of dyeing properties on polyester fabric were discussed via single factor test and orthogonal experiment,including extraction liquid dosage,pH value,dyeing temperature and holding time.The results indicated that brown color could be obtained by high temperature and high pressure dyeing of polyester fabric with Scutellaria baicalensis Georgi dye,and the optimum dyeing process was as follows：dyeing at 130 ℃ for 60 min at pH =5 with the dosage of 50％ extraction liquid.The washing fastness and rubbing fastness of dyed polyester can be grade 4-5,but the light fastness is poor,only grade of 1-2.Moreover,strong UV resistance and certain antibacterial properties are provided on the Scutellaria dyed polyester.
