Dope dyed is a production technique to dye synthetic fibers such as acrylic, nylon and polyester. In the Dope Dyeing, the color pigments are added to the polymer solution, however liquid, before the production of the hilo, so that the color forms part of the fiber. This ensures less color variation between batches compared to traditional dyeing techniques. The traditional fabric of synthetic fibers requires a two-step process: in the first place, the fibers are produced without color; and second, the color is applied to the surface of the fiber. In the Dope Dyeing, one step is eliminated. This reduces water consumption by 90% and the use of traditional chemical products by 98%.
