✦ Synopsis

Beer's law of light absorption and the Kubelka-industry. They described the color of absorbing-scattering substrates in terms of a quantity K/S, which is the ratio Munk analysis are applied to absorbing-scattering fabric.

A relation between the Kubelka-Munk function F(R) and

of the coefficient of absorption K to that of the scattering S. This ratio is taken to be proportional to the concentra-the absorbance of dyed fibers is proposed. The relation is used to predict the absorbance of a colorant from the tion of the colorant. Simmons 4 compared Kubelka and Munk theory with a modified practical model. Also, this reflectance of a substrate dyed with it. Samples of polyester fibers dyed with different colorants are used. The pre-theory and the prediction of reflectance were studied in detail by Nobbs. 5 In 1972, Allen and Goldfinger 6 at-dicted absorbances of these samples agree fairly well with those measured directly on the spectrophotometer.

tempted to predict the color of a fabric based on a model that recognized the discreteness of the individual fibers.
