Abstract
A method of treating filament yarn includes supplying a plurality of yarn filaments through a yarn channel of a nozzle in a yarn travel direction and introducing a blowing medium into the yarn channel substantially in a direction of the yarn travel direction and at an angle of introduction of more than about 15° and less than about 45° from a direction perpendicular to the yarn travel direction. The plurality of yarn filaments are mixed within the yarn channel so as to produce a filament yarn substantially free of knits.
