槐米染料的染色性能及对毛织物的染色工艺

 为研究槐米染料的产业化应用,测试了天然槐米染料的化学成分以及耐热、耐酸碱稳定性,分析了染色温度、pH值、媒染剂用量、染料用量等染色工艺参数对毛织物染色效果的影响,并测试了槐米染色毛织物的抗菌性能。研究结果表明:采用简单的制备方法,就能得到纯度高、耐热稳定性较好的槐米粉末染料;采用优化的铝预媒染色工艺可染得色泽鲜艳、牢度较好的黄色毛织物,且染色毛织物对金黄色葡萄球菌具有杀菌功能,对大肠杆菌、白色念珠菌具有抑菌作用。

Dyeing behavior of natural Flos Sophorae buds dyes and its dyeing process for wool fabrics

For commercial application of Flos Sophorae buds dyes(FSBD),its chemical composition and resistance to heat,acid and alkali were tested,and the effects of dyeing processes such as temperature,pH value,the dosage(o.w.f) of aluminum mordant and FSBD on the result of the dyed wool fabric were investigated.The anti-microbial activity of the dyed wool fabric with FSBD was tested also.The experimental results showed: the FSBD powder,which has high purity and good stability properties to heat and acid,can be produced by the simple and low-cost method;the yellow wool fabric with brilliant shade and good color fastnesses can be obtained by the optimized pre-mordant dyeing process with aluminum;the dyed wool fabric has bactericidal property against staphylococcus aureus and inhibitory effect against bacillus coli and Candida albicans.
