The time-dependent mechanical behavior of textiles has particular importance. One of such behaviors is stress relaxation. When strain is applied constantly, there is a decreased stress with time in viscoelastic materials, which is called stress relaxation. The aim of this study is to investigate the effect of knot’s geometry (surgeon, square and ei...

... order to investigate the effect of knot geometry and its number on the stress relaxation properties of the yarn, three different knot geometries were considered: square knot, surgeon's knot and eight knots ( Figure 1A). The gauge length was kept 25 cm for all samples and the various number of knots (1, 2, 4 and 8) with the same distance 2 cm applied to the yarn ( Figure 1B).To provide uniform tension for different knots, all the knots were applied by one operator manually, and a constant tension applied to each knot for 3 s to ensure not loosening the knot. ...

... course, the tensile behavior of knotted yarns is highly affected by the knot structure, because concerning knot geometry, the compressive and friction loads created in the intertwined region is different. Consequently, it is expected knotted yarns with different geometry exhibit somewhat dissimilar tensile behavior, as it has been observed formerly (Tables 1-4). ...

... Three sutures commonly used in surgery were studied and analyzed. The parameters include the tensile and relaxation properties before and after the knotting, the simulated surgical knotting, the influence of sutures at different speeds, different loads and different surface morphologies and structures on their frictional properties, which are investigated for providing basic data for the design optimization of sutures and surgical suture knotting operations [47]. In recent years, there have been fewer reviews of suture performance studies [48][49][50]; therefore, this review will further summarize the physical properties of sutures and provide reference for future research. ...
With the increasing demand for wound healing around the world, the level of medical equipment is also increasing, but sutures are still the preferred medical equipment for medical personnel to solve wound closures. Compared with the traditional sutures, the nanofiber sutures produced by combining the preparation technology of drug-eluting sutures have greatly improved both mechanical properties and biological properties. Electrospinning technology has attracted more attention as one of the most convenient and simple methods for preparing functional nanofibers and the related sutures. This review firstly discusses the structural classification of sutures and the performance analysis affecting the manufacture and use of sutures, followed by the discussion and classification of electrospinning technology, and then summarizes the relevant research on absorbable and non-absorbable sutures. Finally, several common polymers and biologically active substances used in creating sutures are concluded, the related applications of sutures are discussed, and the future prospects of electrospinning sutures are suggested.
