This paper addresses the bending behaviour of individual multi-filament yarns for use in textile forming analyses. Yarn specimens deform nonlinearly under their own weight in a cantilever configuration. A relation between the applied moment and the resulting curvature is established. Numerical simulations are performed to establish the contribution of shear rigidity to the deflection.

Nanofiber-based nonwoven mats produced in electrospinning setups are usually very fragile, which often limits their applicability. Yarns have the potential to enable incorporation of nanofibers into other materials using well-established techniques such as sewing, knitting, weaving and embroidering, thus broadening application nanofibers. Here, we review development continuous yarn processes. A...

The article is devoted to the study of properties yarn obtained by methods ring and rotor spinning, for twisted yarn, produced on a VTS-09 double twist machine made Volkmann (Germany). Experiments were carried out two typesof spinning yarns with counts Ne 20/2 12/2 in existing design (control) new design, flexible element equal tension intensifier compared effects resulting quality parameters. ...

The twisting stage is one of the most important preparatory stages for yarn it begins with Doubling process in preparation giving suitable twists. A twisted formed by together two or more singles yarns. purpose twist Increase specific durability yarn, C.V Production yarns from mixing and Fancy yarn. modern technology was developed process, achieving advantages at technical economic levels, whic...

The demands for electrochemical sensor materials with high strength and durability in physiological conditions continue to grow and novel approaches are being enabled by the advent of new electromaterials and novel fabrication technologies. Herein, we demonstrate a probe-style electrochemical sensor using highly flexible and conductive multi-walled carbon nanotubes (MWNT) yarns. The MWNT yarn-b...

Efficient physically accurate modeling and rendering of woven cloth at a yarn level is an inherently complicated task due to the underlying geometrical and optical complexity. In this paper, a novel and general approach to physically accurate cloth rendering is presented. By using a statistical volumetric model approximating the distribution of yarn fibers, a prohibitively costly explicit geome...
