Simulation Model for Weft Yarn Motion in a Single-Nozzle Air-Jet Loom
Air-jet weaving is an advanced weaving method with high efficiency and productivity. It is one of the most widely used methods of weaving in the world. In air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. After declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by ...

متن کاملThe Effect of Yarn Hairiness on Air Drag in Ring Spinning
Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This paper investigates the effects of yarn hairiness on air drag in ring spinning. Theoretical models of skin friction coefficient on the surface of rotating yarn packages were developed. The predicted results were verified with experimental data obtained from co...
متن کاملBending and Compression Behaviour of Polyester Air-jet-textured and Cotton-yarn Fabrics
Air-jet-textured polyester yarns were produced using two feed yarns differing in filament fineness and number of filaments. By varying the yarn overfeed, filament fineness and air pressure, four textured yarns were produced. Woven fabrics were prepared using these textured yarns as weft and cotton yarns in warp. To study the effect of air-jet-texturing parameters on the bending and compression ...
