摘要

In order to explore the application of cortex fraxini natural dye in dyeing process, wool fibers were mordant dyed with cortex fraxini natural dye extracted by water extraction method. Dyeing properties of direct dyeing and mordant dyeing using different mordant were compared by K/S value of dyed samples, and the effect of dyeing process containing dyeing temperature and duration, pH value of dyeing bath, amount of the mordant, mordant dyeing temperature and duration on the dyeing properties were experimentally investigated. The better results were achieved by post mordant dyeing with copper sulfate as mordant. The post mordant dyeing process of wool with cortex fraxini natural dye was optimized as follow; dyeing wool at 100 X. for 45 min when pH value of dyeing bath was 4.0, and then post mordant dyeing with 2% (owf) copper sulfate at 100 °C for 30min. K/S value, friction resistance fastness and washing fastness increased obviously for post mordant dyed sample.
