Analysis of yarn properties in the superconducting magnetic bearing-based ring spinning process

The fundamental research work about the superconducting magnetic bearing (SMB) twisting system provides huge potential to eliminate the most important limitation of productivity, that is, the friction in the ring traveler system of the existing ring spinning process. As a continuity of the research work, the functionality of the SMB spinning has been carried out with different angular spindle speeds, yarn counts, and materials in order to determine the influence of the SMB technology. The current paper presents a comparative investigation of the yarn properties, such as yarn tenacity, yarn elongation, yarn evenness, microscopic views, etc., between conventional and SMB ring spun yarn. The intensive analysis confirms that the SMB system enables one to produce satisfactory yarn quality similar to that of conventional ring spun yarn up to 15,000 rpm. The influence of conventional and SMB spinning processes on yarn properties has been further analyzed statistically using an analysis of variance.
