【Abstract】 This article studied the dyeing behaviors of wool fabric with natural vegetable dye turmeric. The factors affecting the process of colorant extraction were analyzed. Based on trials, better extraction effect can be obtained through 20 g /L caustic soda treatment. With extracted turmeric, direct dyeing, pre-mordant and after- mordant dyeing was carried out for wool fabric. According to ΔE, the optimum recipe and condition of dyeing process were settled. The color fastness and bacterial repellency of three kinds of dyed fabrics were also tested.更多还原
