Beer's law of light absorption and the Kubelka‐Munk analysis are applied to absorbing‐scattering fabric. A relation between the Kubelka‐Munk function F(R) and the absorbance of dyed fibers is proposed. The relation is used to predict the absorbance of a colorant from the reflectance of a substrate dyed with it. Samples of polyester fibers dyed with different colorants are used. The predicted absorbances of these samples agree fairly well with those measured directly on the spectrophotometer. © 1997 John Wiley & Sons, Inc. Col Res Appl, 22, 32–39, 1997.
