Elastic recovery is one of the most important mechanical properties especially of clothing applications. This property is more and more significant when the textile structure contains elastane filament and has significant elasticity. In this study, we investigate the effect of the Dorlastan Ò draft and yarn count on the elastic recovery of cottoncovered Dorlastan Ò core spun yarns. These yarns are used as weft yarns in denim fabrics. Dorlastan Ò core spun yarns with different counts 100, 50, and 25 tex, with different elastane drawings and with the same twist factor are used. Our test results revealed that the Dorlastan Ò ratio and yarn count are important factors in influencing the elastic recovery.

“…The problem was in mathematically predicting the exact values of those two properties based on the sole information of the tensile strength and elongation percentage of the yarns used in making those fabrics. This can be attributed to the influence of the fabric structure which influences the total tensile strength and elongation percentage of the produced fabric [8].…”

Breaking strength of yarn is the most important physical property of yarn as it represents the main parameter for physical quality control. Breaking strength of yarn depends on many different factors, namely strength of fiber, length of fiber, micronaire, and uniformity [3].The yarn speed should be kept as constant as possible during warping. In indirect warping a constant speed drive is generally sufficient to provide fairly uniform yarn speed, for some filament yarns variable speed drive is chosen since friction drive would cause problems [1]. Warp yarn tensionA creel for supplying yarns from a plurality of respective packages to a take-up machine, such as a warp winder, has a support defining respective supply stations carrying the yarn packages, respective tension-sensing deflectors at the stations, and guides for directing the yarns from the respective packages over the respective braking surfaces and around the respective deflectors [4]. AbstractWarping is aimed at preparing the weaver's beam to be set up on the weaving machine. In warping, the yarns are taken from the spools placed on the creel and are wound around the warp beam or roll as per the calculated width of the fabric, an uninterrupted length of hundreds of warp yarns results, all oriented parallel to one another.This paper reports a study on producing (27) yarn samples by an indirect warping machine (Benninger, Ben-Ergotronic). Samples of yarns were manufactured from continuous raw polyester filaments with three yarn counts (70,150,300 denier) under three applied tensions of (0.15, 0.22, 0.29 cN/dtex). In addition, three warping speeds (200,400,600 m/min) were used. Tensile strength and elongation at break were measured.The results of measurements of warp yarn count under study for tensile strength and the elongation under the application of the set tension and warping speeds showed optimum tensile strength at warping speed of 400m/min, under a tension of (0.22) cN/dtex. In addition, the optimum elongation percentage was at warping speed of 200m/ min, under a tension of (0.22) cN/dtex for the (70) denier yarns. For (150) and (300) denier yarns, the optimum tensile strength and elongation percentage were at warping speed of 600m/min, under a tension of (0.29) cN/dtex.

“…They dealt with the structural interactions that occurred during tensile cycling of marine ropes, and attempted to model the combined effects of fatigue and wear in some common rope systems. We have previously studied the effect of tensile fatigue on the mechanical properties of polyester, nylon and polypropylene filament yarns at two different strokes and frequencies [9]. We observed that for all yarns and loading conditions, the storage modulus of the yarn increases, and for all loading conditions, the loss modulus of nylon and polypropylene yarns decreases.…”

Fatigue is the decay of mechanical properties after repeated application of stress or strain that can lead to the failure. The fatigue behavior of textile materials is important not only during the textile process such as warp yarn fatigue during weaving, but also in their performance in technical and medical applications such as tyre cord, composite fabrics, ventricular restraint devices and artificial vascular grafts. Some experimental works have been performed by previous researchers on the fatigue behavior of fibers, yarns and fabrics. However, no theoretical and modeling studies have been observed on these materials.Lyons [1, 2] studied the tensile fatigue behavior of some textile fibers and his results showed that the stroke, frequency of cyclic loading and temperature affect the fatigue behavior. He observed that the number of cycles that the fiber sample withstands before rupture increases with increasing frequency, even though the time to rupture decreases. He also showed that at a constant frequency, with increase in stroke, there is a consistent decline in average lifetime. The same result was reported by Prevorsek and Lyons [3,4], who investigated the effect of stroke on the fatigue lifetime of a number of man-made fibers under tensile fatigue. Frank and Singleton [5] studied the factors influencing tensile fatigue behavior of yarns. They found that plasticizers in the form of heat and/or water tend to increase the fatigue life of yarns. 1 They observed that the withstand strengths of nylon, polyester and viscose rayon yarns against the cyclic deformation based on the frequency of cycle straining, temperature, humidity of ambient, are different from each other and depend on the structure and physical properties (regain and thermoplastic properties) of these yarns. Anandjiwala et al. [6,7] studied the tensile fatigue behavior of staple yarns under cyclical elongation accompanied by abrasion. They found that increase in the pretension decreases the resistance of the yarn under applied Abstract This study focused on the prediction of fatigue behavior of plain woven fabrics using the yarn fatigue property and the structural-mechanical parameters of the fabric. For this purpose, the Eyring viscoelastic model was developed as a theoretical analysis to predict the fabric elongation while subjected to a constant cyclic load. It was suggested that the elongation of the fabric under constant cyclic load consists of three parts: fabric decrimping arising from yarn slippage in the fabric, yarn decrimping, and finally yarn elongation. Comparison between the theoretical and experimental results for different weave densities of fabric revealed a reasonable agreement between them. It was concluded that an increase in weave density leads to decrease in fabric fatigue.
