ABSTRACT

In this paper, the response surface method was used to study the technology of dyeing wool fiber with walnut green peel pigment under the microwave-assisted method. The optimized pigment extraction process were: ethanol volume fraction 60%, extraction time 1 min, liquid-material ratio 24:1, microwave power 450 W, and the optimized mordant fixation process were: mordant fixation time 3 min, microwave power 270 W, amount of mordant fixing agent 7%, reducing agent dosage 22 g/L. The results showed that the use of microwave-assisted and new mordant fixing agent lanthanum chloride greatly improved the extraction efficiency of pigments, saved extraction costs, and significantly shortened the mordant fixation time, resulting in an environmentally friendly mordant fixation process.

摘要:

采用响应面法研究了微波辅助下核桃青皮色素对羊毛纤维的染色工艺. 优化的色素提取工艺为:乙醇体积分数60%, 提取时间1min, 料液比24:1, 微波功率450w, 优化的媒染剂固定工艺为:媒染固色时间3分钟,微波功率270W,媒染固色剂用量7%,还原剂用量22g/L. 结果表明, 采用微波辅助的新型媒介固色剂氯化镧, 大大提高了色素的提取效率, 节约了提取成本, 显著缩短了媒介固色剂的固色剂固定时间, 形成了一种环境友好的媒介固色剂固定工艺.
