Friction spinning machines are totally unique and have
a wide range of uses. They can be employed to produce special
fibres such as stainless-steel and glass fibres and are
the only systems of this kind that can cover an entire core
filament. As a result, they are the best machines for producing
high-tech textiles.
Friction spinning machines are based on the simple yet innovative
concept of winding sheath yarns around a core yarn using
rotating suction drums. Schoeller has worked with DREF®
3 machines for a number of years now and so has considerable
experience in this area.
The DREF® 2000 features six heads and is now being used
by Schoeller to spin coarse hybrid yarns. These can be used
in protective clothing, fire-resistant material or as an
asbestos substitute. Additionally, as the machines can spin
long-staple yarns in the sheath, they open up a host of
new possibilities for developing functional textiles that
will bring real benefits to customers.
