In this work, raw fibers of a local species of stabraq (milkweed) were scoured and bleached with alkaline treatment. The improved stabraq fibers were subjected to dyeing with two types of disperse dyes at 1% owf in a liquor ratio of 30:1, in the exhaustion dyeing method. The effects of various factors which may affect the dyeability property and color fastness of the treated fabric, such as alkali and dye concentration, were studied. Furthermore, CIE L*, a*, b* value, washing, light and stain fastnesses of the treated fabrics were evaluated. The results suggested that the dyeability of modified stabraq fibers with two disperse dyes used, resembles that of other cellulosic fibers more closely.
