Systematic investigation and evaluation of modified ring yarns by feeding three-roving strands

Abstract

Spinning is one of the major steps in textiles to convert staple fibers from either natural or synthetic sources into continuous and twisted yarns, and ring spinning has always been the dominant yarn technology since its invention. Recently, many ring-based modifications have been developed to improve yarn productivity and properties. In this work, a modified ring spinning technique has been developed by feeding three-roving strands into a conventional ring frame for producing yarns with better performance. A strand delivery guide with different spacings (1–5 mm) was used for the production of three-strand yarns. The quantitative relationships between the spinning parameters and yarn properties have been systematically investigated. The properties of the modified yarns were evaluated, including yarn tensile properties, evenness, and hairiness, and the statistical relationships were obtained by least squares polynomial fitting. The experimental results indicate that the guide spacing and twist multiplier significantly influence the yarn properties. The spinning triangle of the modified yarns resembles Solospun yarns, suggesting supreme yarn abrasion performance.

An analogical method for evaluating ring performance based on quality and production parameters

“…The condensed yarn was produced by Murugan et al using a mingling chamber installed in the front drafting zone of a traditional ring-spinning machine [ 14 ]. To improve performance, Ling et al put three roving strands into a typical ring frame [ 15 ]. In a study on the temperatures of the traveller and ring during ring spinning, Wu et al looked at the impact of the traveller's weight, yarn count, twist level, and spindle speed [ 16 ].…”
