The article presents the dependence of the change in the intensity of emission during the passage of an infrared flux through a two-component material, which allows for a fractional assessment of a mixture of natural and chemical fibers. On the basis of the obtained dependence on experimental data, a mathematical model has been constructed that makes it possible to quantify the distribution of dissimilar fibers in a mixture. The modelling results showed that after the second transition on the draw frame, the so-called "stretching" defect is observed, which characterizes the uneven distribution of fibers in the product cross section.
