MATHEMATICAL MODELING OF SOME INFLUENCE FACTORS OF YARN IRREGULARITY

Adina BUCEVSCHI, Alexandru POPA, Dan Ovidiu GLĂVAN

Abstract


The design of fiber mixtures and the estimation of the characteristics of the yarns obtained is a current issue, taking into account that commercial companies receive orders for small quantities of products, which means changing the mixing recipes, changing the adjustments of the machines but also knowledge of the characteristics of the yarns that will be obtained. Blends of cottonised flax and cotton in the context of the evolution of the textile market can be considered an important opportunity for the textile industry. Mathematical modeling used to optimize yarn parameters is based on the central program, compound, rotable with two variables. Within the program used the independent variables considered are the percentage of cottonised flax in the mixture (x1) and the yarns count (x2) and the dependent variable is the Uster irregularity of the yarns.
