SWICOFIL - Yarn and fiber expert.


Yarn spun by air stream.
With air jet spinning, the tenacity of the yarn is created by twisting the fibers on the verge around the core fibers. The inner fibers thus experience no twist.

This twisting is done by two air nozzles. These nozzles blow the outer fiber around the fibers in the core. Thank to the rotating air stream, the outer fibers are twisted around the core fibers, thus creating sufficient tenacity to form a yarn.


Spuns made by air jet spinning have a good orientation (meaning do not have a wild appearance like open end spuns). Important with air jet spinning is to use fibers that are sufficiently long, as short fibers are stiff and thus not optimal to use for creating enough friction.
