Abstract

The invention provides a green dye-assisting butterflybush flower cloth dyeing method. The method comprises two steps of dye liquor preparation and cloth dyeing, wherein dried butterflybush flower isused as a raw material of plant dye during the dye liquor preparation, and water or ethanol as extractant. The dyeing capability of the butterflybush flower dye liquor on three fabrics (cotton, hemp and silk) is improved by using green dyeing assisting in three mordant dyeing modes of first mordanting and then dyeing, first dyeing and then mordanting and one-bath mordant dyeing. The green dye-assisting butterflybush flower cloth dyeing method has the advantages of simple operation, wide application and environmental protection, and the dyed cloth has bright color and high color fastness.
