Wetted Air Texturing and Water Application
topic
Wetted air texturing applies a fine water spray or water immersion to the yarn immediately before the air jet nozzle, with water acting as a lubricant that reduces inter-filament friction enabling more uniform loop formation and higher loop density compared to dry air texturing, with water application rate of 3 to 10 percent on weight of yarn being the critical parameter governing loop formation efficiency and the surface softness of the wetted air-textured yarn.
Role
Improves air texturing loop formation quality and consistency by lubricating filament-to-filament contacts within the turbulent nozzle zone that allows more uniform individual filament separation and looping, with wetted texturing producing denser, more uniform loop structures than dry texturing for fine filament yarns where inter-filament cohesion without water would prevent the individual filament separation needed for effective loop formation.
