Correlation between nozzle structural parameters and breaking strength of jet vortex spun yarn

Abstract

Based on the mechanical analysis of the forming process and tensile fracture of jet vortex spun yarn, this article establishes the theoretical calculating system of the breaking tenacity of jet vortex spun yarn. The relationship between the twist length of the fiber and the breaking strength of jet vortex spun yarn is proposed. Using both simulation and experiments, key structural parameters of the components which impact on the twist length of the fiber more obviously were analyzed, such as the angle between the nozzle hole axis and the horizontal, the distance between the nozzle hole and the nozzle axis, and the inner diameter of the nozzle. By optimizing the combination of these nozzle structural parameters, the twist length of the fiber is increased to achieve better wrapping effect, and larger yarn breaking strength. This research lays a theoretical foundation for enhancing the strength of jet vortex spun yarn that can be helpful in guiding production.
