    Abstract: The colour and dyeing properties temperature range and rate of dyeing of 14 hetarylazo disperse dyes previously synthesized and applied by exhaustion on cellulose acetate were evaluated visually and instrumentally and the results were compared and reported. A satisfactory agreement between the visual and the instrumental evaluation of these propert... Show More
