“…The elastic recoveries decrease when the yarns are subject to five elongation-cycles. The yarns suffer from a loss of their partial elasticity 39 and an accumulation of plasticity 40 following cyclic tests. As a result, the second creep is conducted.…”

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.

“…In that way, the core-yarn's tenacity and elongation decreased while the elastane percentage increased [8,9,18]. Elastane draft effects breaking tenacity and elongation [10]. On the other hand, higher draft ratio causes decrease in elastic recovery of elastic core spun yarn [6].…”

“…In the literature, many researchers have been focused on elastane containing core-spun yarns in terms of elastane draft, elastane ratio, elastane linear density, elastic yarn positioning, twist factor etc. in order to obtain optimum yarn properties [2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18]. When twist factor increases, it will affect the tensile properties of elastic cotton core-spun yarn positively [12,18].…”

Elastic core-spun yarns which is used as weft yarn for textile fabrics gained great importance in the last decade its due to the fact that stretch and recovery, comfort fits and flexibility properties. The technological progress made the dual core-spun yarn production possible. The dual core-spun yarns are composed of filament that contributes durability and polyurethane based elastane that provides stretchability to the fabrics. Hereby, both filament and elastane characteristics have great influence on denim performance at the same time. The main purpose of this study is to achieve the effect of filament fineness and elastane draft on denim fabric performance such as breaking force, breaking elongation, tear force, vertical elastic recovery, moisture management that is wicking rate and water absorption properties. Meanwhile, filament core-spun yarns with different filament fineness and 100% cotton yarn were also used as weft of the denims in order to investigate the differences statistically. It was found that that filament fineness and elastane draft had statistically significant effect on all inspected performances of denim fabrics except water absorption.

“…spun yarn during the cyclic test proved the existence of a constraint threshold (S) from which the elastic core spun yarn keeps a permanent constraint. This factor explains the existence of the fourth zone at the end of the tensile curve and consequently the existence of the shoe in the model suggested to describe the mechanical behaviour of the elastic core spun yarn [15].…”
