- Annotation: The article presents the results of a study of the relationship between irregularity in linear density and the proportion of components of one-dimensional fibrous products (tape, tourniquet, roving, yarn). A formula is obtained for estimating the coefficient of variation for the component fraction depending on the unevenness for the linear density and the average component fraction. The estimate allows one to predict the expected unevenness of the component share in the product based on known information about the unevenness of the components. Regularities are established and examples are given of the relationship between correlation functions and spectral dispersion densities for unevenness by linear density and component share in the product depending on the share of components, their unevenness, and the spectral composition of the unevenness.
