3 principle

3.1 staining method Dyeing was carried out on the appropriate fibers (wool, nylon) under the same conditions as the standard sample of the same variety using an acid dye sample. then The color intensity and intensity of the sample were evaluated by visual comparison with the color intensity of the standard sample of 100 points and the color light as the standard. Or with a colorimeter Line color, and then calculate the color and intensity of the sample. 3.2 solution colorimetric method When the dye solution meets the Lambert-Beer law, the acid dye sample and the standard sample are fixed in water and then measured with a spectrophotometer Determine the absorbance of the maximum absorption wavelength, you can calculate the intensity of the dye sample. In the absorbance values are basically the same, in the color tube in the head The color of the sample can be assessed by comparing the color difference between the standard sample and the sample.
