DREF set the pace in exploiting waste !

At present, 8,481 DREF 2 spinning heads manufacture approximately 318,000 metric tons of yarn annually in the Nm 0,5 - Nm 6 (2000 - 167 tex) yarn count range. 230 of these machines, with yearly yarn production of 80,100 metric tons, are employed in the cleaning cloth and mop sector.

Following the world market launch of the DREF 2 in 1977, leading cleaning cloth and mop manufacturers from Europe and overseas began to switch from conventional carded yarn operation to friction spinning.

This decision was influenced by the following notable advantages:

  - Savings in material costs due to the use of 100% regenerated fibres, spinning waste and
    cotton waste blends.
  - The economic and problem-free, high-performance processing of extremely short staple
    materials (10-20 mm staple length) through the feeding of a yarn core (e.g. 167 dtex,
    texturised, PES sub-standard filament), or of a core-sliver from PES regenerated fibres
    (instead of a yarn filament core).
  - Reductions in personnel costs (simpler preparation as the material passes directly from
    the card to the spinning machine).
  - Increased efficiency (up to 95%) due to greater bobbin weights of up to max. 8 kg and
    spinning without yarn breaks.
  - Considerable increases in performance due to the production of heavier slivers with weights
    of up to 15 g/m.
  - Greatly improved water absorbency capacity and improved retentive volume.
  - Higher fabric weights and a cleaner cloth appearance.

Furthermore, DREF allows the manufacture of both S- and Z-twist yarns with the same machine. This means that the cloth ends do not curl, which is a major advantage with regard to further processing on automatic sewing machines.

In other words, DREF 2 offers a package of benefits for the mop and cleaning cloth yarn market that are simply too good to ignore.
