Abstract:

The verification of models based on multiple regress servants for the assessment of the ring spinning process of classic as well as compact cotton yarns was carried out. The analysis of results obtained showed that the statistical models proposed were very useful in making a qualitative and productive comparison of the yarns considered. Decreasing the metric coefficient of the twist - ám and percentage noils - pw during the production of compact yarn makes possible the obtainment of significant productive effects and the lowering of the costs of producing the yarn without an excessive worsening of quality.

Tags: ring classic yarn, compact yarn, percentage of noils, twist coefficient, spinning plan, total experiment, double classification, multiple regression.
