Investigation of the effect of core-yarn wetting on air-jet and steam-jet spun-like texturing performance

Abstract

The objective of the research work was to investigate the use of steam as an alternative fluid for air in spun-like textured yarn manufacturing and to investigate the effect of wetting on texturing performance. An existing air-jet texturing machine was modified to supply either air or steam to the texturing nozzle. Both air-jet and steam-jet textured yarns were made using the same process parameters with and without core-yarn wetting. The effect of core-yarn wetting on the texturing performance has been studied. Results show that core-yarn wetting is critical for air-jet texturing but do not have considerable impact on steam-jet texturing. Therefore, core-yarn wetting could be eliminated in steam-jet texturing. Further, steam-jet texturing shows its capability in manufacturing spun-like textured yarns with better performance than the air-jet. Therefore, it can be concluded that steam can be used as an alternative fluid for air in making spun-like textured yarns without core-yarn wetting.
