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

本文采用响应面法研究了核桃绿皮色素在微波辅助下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1 min，液料比24：1，微波功率450 W，最佳媒染剂固定工艺为：媒剂固定时间3 min，微波功率270 W，媒染剂的用量为7％，还原剂的用量为22 g / L。结果表明，微波辅助和新型媒染剂氯化镧的使用大大提高了颜料的提取效率，节省了提取成本，大大缩短了媒染剂的固着时间，从而实现了环境友好的媒染剂固定过程。
