| dc.description.abstract | Open end rotor yarns were spun at six different counts, each count at five different, speeds on a BD 200 machine. A constant twist factor and fixed opening roller speed were used throughout the spinning operations. Cutting and weighing technique was used to analyse the spun yarns to assess the influence of speed and count variation on the irregularity of the OE-rotor yarns. Uster evenness tester was used to analyse the yarns for irregularities, neps, etc. From the results obtained, it became clear that increasing rotor speed increases the level of irregularity in OE-rotor yarns, and increasing the yarn count (tex) from fine to coarse values also increases the level of irregularity of the rotor yarns analysed. It was observed that the level of irregularity in the yarns produced was low compared to that of rotor yarns of similar counts reported in the literature. | en_US |
