Friction Spinning Systems for Specialty Structures
topic
DREF friction spinning machines use two rotating rollers with suction applied in the nip zone to collect individualised fibres from an opening roller stream, twisting them together by frictional surface contact to produce coarse count yarns at 200 to 400 metres per minute for fire-resistant yarn blends, decorative yarns, and waste fibre utilisation where the open yarn structure and coarse count characteristics are acceptable for the application requirements.
Role
Produces specialty yarn structures for fire protection and industrial applications from fibre blends that are difficult to process on conventional ring or rotor spinning through the core-sheath fibre arrangement and open yarn structure of DREF friction spinning, enabling utilisation of short, contaminated, or blended fibre streams that other spinning systems cannot process at the coarse counts used for protective and industrial yarn applications.
