E-textiles based on yarn-based sensors have been a topic of intense research. In our previous paper, a straightforward way for fabricating tri-component elastic-conductive composite yarns (t-ECCYs) with a unique architecture applicable to yarn-based sensors was proposed using a modified ring-spinning frame. Herein, a comparative analysis of the physical characteristics of t-ECCY, bi-component elastic composite yarn (b-ECY), bi-component conductive composite yarn (b-CCY), and single rayon yarn (s-RY) are presented, in detail, in terms of tensile behavior, elastic recovery, electrical resistance, unevenness, and hairiness. In particular, a systematic study of the tensile and conductive properties of yarns appropriate for e-textiles, that is, t-ECCY and b-CCY, are highlighted. In addition, a non-invasive structure verification technique is conducted to identify the dispositions of constituents inside the yarn. It is found that the t-ECCY exhibits a remarkable improvement over the other yarns, having robust tensile properties, super elasticity, stable electrical durability, lower unevenness, and hairiness. A simple tensile model has been proposed to predict the t-ECCY’s tensile strength, and the substantial improvement in the tensile properties of t-ECCY compared with the b-CCY can be associated with the distinctive yarn structure. The stretch-deformation mechanism of coils in the t-ECCY is, initially, separation of adjacent surfaces of coils and gradual unwinding till free. Benefiting from its superior conductivity and elasticity after single/cyclic stretch tests as well as other properties, the t-ECCY itself can serve as a sensing element, which could be a highly valuable use for specific purposes in smart textiles.

“…Influence of spinning parameters on the core yarn sheath slippage was also studied (Miao, How, & Ho, 1996). Some other researchers have also worked on the spinning methods other than the modified ring spinning for producing core-spun yarns (Dang, Zhang, & Wang, 2006;Lin, Chang, Lou, & Hsing, 2004;Ortlek, 2006;Ortlek & Ulku, 2007).…”

The aim of this study was to investigate the effect of elastane linear density and draft ratio on the physical and mechanical properties of core-spun yarns. Twenty yarn samples were prepared on industrial scale in a spinning mill with two different yarn linear densities, each with different two elastane deniers and five draft ratios. It was found that core-spun yarn's tenacity, elongation and hairiness are affected not only by the overall yarn linear density but also by the elastane linear density and the draft ratio. However, the effect of elastane linear density and draft ratio was not found to be statistically significant on the yarn mass variations and total imperfections, which are only affected by the overall yarn liner density. A statistically significant interaction for yarn elongation at break was found between the yarn liner density and the elastane linear density concluding that elastane linear density used in the core must be compatible with the overall yarn liner density for attaining the best yarn elongation.
