    Abstract: A method of dyeing a fibrous textile material composed of an acrylonitrile polymer in level shades with a cationic dye from an aqueous liquor by carrying out the dyeing at a predetermined temperature T which is dependent upon definite liquor exhaustion rates, a constant a which denotes the change in temperature which halves or doubles the liquor exhaustion rate measured at a dyeing temperature of 100* C and a constant b which denotes the depth of color to be achieved in milligrams of dye per gram of fibrous material.
