Abstract. The article considers the improvement of methods for testing the color fastness of textile materials with the replacement of the visual method with an objective colorimetric evaluation method. A new method for testing the color fastness of textile materials is proposed.The analysis of domestic and foreign standards that establish the calculation and establishment of color fastness standards for cotton fabrics and their comparison with the norms of international and domestic standards was carried out. It is shown that the development of methods for instrumental determination of color fastness to friction, which is an alternative to the method of visual assessment of the color fastness of any textile material on a gray scale, is currently an urgent and promising scientific and technical task.A new method for testing the color fastness of textile materials is proposed. The overall color difference (ΔE) between the test sample of the color fastness test material and the original sample was measured. For both samples, the overall color difference was determined in the CIEL*a*b* system, the values of which are converted into equivalent points on a gray scale. The score in terms of the value of ΔE was calculated on a computer using the Ecsel environment and displaying the calculation results on the display screen.
Keywords: standard, color, stability, friction, general color difference.
