Theory of mass irregularity changes in the OE-rotor spinning system

Popis výsledku v původním jazyce

In the work a theory of yarn mass irregularity changes in the OE-rotor spinning technology is presented. Three various approaches are described. In the first we assume the OE-rotor spinning system as a dynamic system and use the random mass function of short section of sliver and yarn as a function of time and we construct so called modulus of the transfer function. In the second approach we analyse the mass irregularity formation on the basis of the laws of variation phenomena in random processes. We express the total square mass irregularity by means of individual components which are influenced by technological process of final yarn formation. In the last approach we solved influence of OE-rotor spinning system on the yarn mass irregularity formation depending on the yarn fineness. We theoretically derive ratio of changes of draft of opening system and number of cyclic doubling as a function of OE-rotor yarn fineness. This ratio increases with decreasing value of yarn linear density. Increase in ratio corresponds with increase in mass irregularity. The described analysis is applicable for research of optimal technological conditions for OE-rotor spun yarn production.
