The air-jet texturing process, a purely mechanical means of texturing continuous filament yarns, is described. Industrial texturing nozzles are reviewed and categorized in two groups, either as converging-diverging or cylindrical type nozzles. ... A Study of Air-Jet Texturing Nozzles: The Effects of Nozzle Configuration on the Air Flow. J. Eng ...
Get PriceThe first type, which is a venturi type air jet and a more recent development a vortex type of air jet. Both jets operate at pressures of around 10 bar 140 psi. In both cases, the actual texturing happens directly outside the jet in the turbulent supersonic air stream. The jet producers offer a variety of jets for different deniers and yarns.
Get Price2017-8-29 · The machine was designed originally to supply compressed air to the texturing nozzle. At the start of the steam-jet texturing research, the machine was modified to supply either compressed air or high-pressure steam for the texturing nozzle. The jet box seal was modified to prevent steam and condensate from escaping. This also reduced the
Get Price1990-2-1 · A thorough investigation of the existing texturing nozzles will, no doubt, lead to the design of improved nozzles. This paper reports the experimental research carried on the scaled-up versions of the T100 HemaJet with varying geometrical configurations, being the exit shape, situation, and inclination of the inlet holes, and the ratio of the incoming holes area to the nozzle…

The yarn exit end of these cylindrical nozzles is often trumpet shaped.
Get Price2016-7-20 · Air-jet texturing is a pneumo-mechanical bulking different jets. Attempts to bulk spun yarns in air-jet process in which a bundle of multifilament yarn is texturing by the present authors revealed that the new overfed into a nozzle and subjected to an air stream, jets have an untwisting action on the yarn II -13 and
Get PriceAir-jet texturing is a versatile process for producing a range of synthetic yarns with a spun-like appearance, which are widely used for apparel and furnishing fabrics and industrial textiles.There is no universal nozzle capable of processing any supply yam of any linear density.The role played by nozzle geometry is still not fully understood.The experimental study presented here seeks to ...
Get Price2020-4-22 · the nozzle geometry: Nozzles 1-9 have nine different values of primary flow length LP, i.e., the distance between air inlet and nozzle exit, ranging from 4 to 16 mm. The reference nozzle is nozzle 5 with a value of LP of 10mm. Nozzles I 0 and 11 have two different angles a of the air inlet hole to the main channel, 30° and 60°. The inlet angle

The air-jet texturing process forms a yarn with tightly convoluted, entangled and looped filaments resembling yarns spun from staple fibres such as cotton and wool. In this process of air-jet texturing, multi filament yarn is fed into a narrow channel
Get Price2020-1-10 · Air-jet texturing is one of the most popular texturing methods. Unlike other tex-turing methods it is a fully mechanical process using a turbulent ßuid, which is usually compressed air. Loops are formed on the surface of the Þlament yarn, giv-ing it a voluminous character [5Ð7].
