2021-8-2 · Air-jet spinning is also known as Vortex or fasciated yarn spinning. It was introduced in the 1980s. A basic air-jet spinning system is shown in Figure 9.12.Before the sliver from the drawframe is supplied to the air-jet spinner, combing is often used, as it is imperative to get rid of any dust or trash that could obstruct the spinning jets.
