Effect of filament positions on the properties of core yarns produced by embeddable and locatable spinning

Abstract

To investigate the impact of positional changes of the strand and filament on the performance of embeddable and locatable spun (ELS) core yarns, various parameters were set for ELS systems to produce different yarns. The experiment involved controlling the distance between the strand and filament, as well as the distance between strands. The yarns were then subjected to systematic testing and analysis to evaluate their hairiness, dryness, strength, and abrasion resistance. The experimental results revealed some significant findings. Firstly, increasing the strand spacing from 1 mm to 5 mm led to a consecutive reduction (most by 33.3%) in hairiness for 3 mm distance. Secondly, when the strand spacing was set at 3 mm, the yarn strength increased by 6.8%. Furthermore, by maintaining a fixed strand spacing, increasing the distance between the filament and strand resulted in further reduction of yarn hairiness and improved overall yarn strength. Regarding abrasion resistance, the best performance was observed at a strand spacing of 2 mm. Additionally, the overall abrasion resistance of yarns with increasing strand spacing was superior to that of yarns with varying filament positions. Understanding the relationship between filament positions and yarn properties holds practical significance for the advancement of high-performance composite yarns.
