摘要/Abstract

摘要： 采用水提取法从黄连药材中提取黄连素，用提取产物黄连素对锦纶6织物进行染色，分析了提取产物的基本性能，研究了染色温度、pH值和元明粉用量对染色织物K/S值的影响，探讨了黄连素在锦纶6上的提升性能、吸附性能以及染色织物的牢度。研究表明，用水提取法一次提取即具有较高的效率，提取产物的主要成分为黄连素，染色织物的K/S值随着染色温度的升高逐渐降低，随着染色pH值的升高逐渐增加，元明粉对染色有一定的缓染作用，高温条件下黄连素在锦纶6上的吸附速率远快于低温条件，黄连素在锦纶6上的吸附符合Langmuir吸附模型，染色织物经固色后各项牢度均在3级以上。

Abstract: The water extraction technology was applied to extract berberine from Coptis chinensis Franch. The extracts were applied to dyeing of nylon 6. The basic performance of extracts and the effects of dyeing temperature, value of pH and sodium sulfate dosage on K/S value of dyeings were analyzed. The good building-up property, absorption performance and color fastness of berberine on nylon 6 were also investigated. It was found that the basic component of extracts was berberine. The K/S value of dyeings was decreased with the increase in dyeing temperature, but increased with the increase in dyeing pH. The dyeing rate was increased with the increase in dyeing temperature, Langmuir equation can better fitted the absorption of berberine on nylon 6. The color fastness of dyed fabrics were above 3 class after treatment with fixing agent.

Key words: berberine, nylon 6, dyeing, absorption, natural dye
