Abstract:

The analysis of the parameters of the spinning process was conducted of the quality of the yarn and the efficiency of the production, and it was confirmed that the percentage of noils and the metric coefficient of the twist were important factors. The analysis of the simultaneous influence of both factors on the chosen properties of classic cotton yarns, and of the nominal linear density 20 tex of compact yarn, was conducted by means of statistical models based on multiple regression, after conducting two total experiments of the type 5 × 5. The verification of proposed models will be presented in the second part of the article.

Tags: classic yarn, compact yarn, percentage of noils, twist factor, Rieter company spinning plan, total experiment, double classification, multiple regression.
