中药诃子制备的天然染料对棉织物的染色研究

Research on Dyeing of Cotton Fabric with Natural Dye Extracted from Terminalia chebula Retz

本文研究由中药诃子制备的天然染料对棉织物染色方法,分别采用非媒、预媒、同媒和后媒四种染色方法,并运用多种媒染剂进行染色试验。研究结果表明:采用优化的铝预媒染色工艺可染得色泽鲜艳,色牢度较好的黄色棉织物。

The aim of this work is to study the effect of dyeing cotton fabrics with a natural dye extracted from Terminalia chebula Retz..Four dyeing methods(non-mordanting,pre-mordanting,simultaneous mordanting,and post-mordanting methods)and several mordants were tested.The results show that the cotton fabrics get yellow and better results with respect to both light and fastness when applied by the optimized aluminum pre-mordanting method.
