栎树叶色素对羊毛织物的染色及拼色

Dyeing and combination dyeing of wool fabric with oak leaves pigment

以栎树叶提取液对羊毛织物染色,探讨媒染剂对染色性能的影响,并以栎树叶色素与苏木色素2种天然染料对羊毛织物进行拼色实验,研究2种染料的配比对染色效果的影响。结果表明,直接染色以及Fe2+、Cu2+、Al3+后媒法染色可以分别染得不同色泽的羊毛织物,其中硫酸铜媒染样品所测各项牢度均达到4级。栎树叶染料与苏木染料拼色样品的色光、色深及染色牢度均随2种染料浓度变化而呈现规律性的变化,拼色及媒染可进一步丰富色泽。

Wool fabric was dyed with extract of oak leaves and the effect of mordant on the dyeing properties was explored, the combination dyeing experiments were also carried out by the use of oak leaves pigment and hematoxylin pigment, the effect of the ratio of the two kinds of pigment on dyeing behavior was studied. The result showed that direct dyeing and post-mordant dyeing with Fe^2＋ ,Cu2＋ and Al3＋ can get various color wool fabric, respectively, the measured color fastness of samples mordant by copper sulfate up to grade 4. The combination dyeing samples with oak leaves pigment and hematoxylin pigment were presented regular changes on shade, color depth and color fastness with the two pigment concentration, combination dyeing and mordanting enrich the color.
