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.
Get PriceThe mechanism of particle removal was studied using a high speed air jet. The experiment was conducted for latex particles of 1∼10μm diameter adhering to a plane surface of glass under various jet pressures and impinging angles. It was found that the removal force decreased with decreasing the impinging angle below 45°.
Get Price2006-2-1 · A comprehensive review of the roles played by the airflow, wetting and spin finish on the air-jet texturing process is given. The results of an experimental investigation of the air-jet texturing process using residual spin finish, yarn-to-yarn static and kinetic friction, filament strength, filament diameter, and on-line tension measurements and high-speed cine-photography are reported.
Get Price2010-10-8 · precise mechanism by which the process occurs has not been examined in detail. It is unclear how the disturbances on the jet surface trigger the entrainment and, once it is triggered, how much air is entrapped inside the pool. The e ect of other parameters such as jet speed, turbulence level, nozzle geometry, viscosity of the liquid, etc. are
Get Price2004-6-29 · The Fundamentals of Air-Jet Texturing. Air-jet texturing is a well-established filament yarn processing technology that has been around for more than half a century. There is much debate about various aspects of the process in the literature such as the mechanism of loop formation, role of water in air texturing and the influence of process ...
Get PriceAn unexpected finding is that the role of the jet is not simply that of conveying the disturbance to the pool surface. Rather, both the observed energy budget and the simulations imply the presence of a mechanism by which part of the jet energy is used in creating the cavity. A hypothesis on the nature of this mechanism is presented.
