摘　　要：为了研究板栗壳色素在锦纶织物上的染色性能，探讨了染色温度、染浴pH值、色素质量分数、NaCl质量浓度对板栗壳色素上染锦纶的影响，比较了直接染色和先媒后染工艺染色织物的颜色特征、染色牢度和防紫外线性能。试验结果表明，板栗壳色素上染锦纶的最佳工艺为pH3～3．6，温度95℃；中性电解质的加入将降低色素的上染百分率；板栗壳色素对锦纶织物具有较好的提升性能，染色织物的色牢度均在4级以上，媒染对板栗壳色素上染锦纶的色牢度和色光影响很小，经板栗壳色素染色的锦纶织物具有优良的防紫外线性能。To study the dyeing property of chestnut shell pigment in nylon fabrics, this paper discusses the mlluence of dyeing temperature, pH value of dye bath, mass fraction of pigment and mass concentration of NaC1 on dyeing of nylon with chestnut shell pigment and compares color feature, color fastness and ultraviolet resistance of fabrics with direct dyeing and fabrics subject to the process of first mordanting and subsequent dyeing. The experimental result shows that the optimal process of dyeing of nylon with chestnut shell pigment is pH3 - 3.6 and temperature 95 ℃. The addition of neutral electrolyte will reduce the dye uptake of pigment; chestnut shell pigment can improve the performance of nylon fabrics ; color fastness of dyed fabrics is over level 4 ; mordant dyeing has little influence on the color fastness and colored light of dyeing of nylon with chestnut shell pigment; nylon fabrics dyed with chestnut shell pigment have good uhraviolet resistance.
