Process of Compacting

Compacting takes place in the compacting zone following the main drafting zone of the drafting system. The drafted fibre strand is compacted before twist is imparted, meaning fibres are arranged in close and parallel position to one another. And by using the EliTe®CompactSet, this effect is achieved thanks to an air flow produced by a vacuum and an inclined slot:

  • Normal drafting is carried out by a conventional drafting system.
  • When the open fibre strand leaves the clamping line of the main drafting zone, a lattice apron will guide it over an inclined slot that is under negative pressure
  • At the edge of this slot the compacting of the fibre strand will start , i.e. the absolutely close and parallel positioning of the fibres.
  • The tension draft between the front top roller and the EliTe®Roller also supports the compacting effect.
  • The fibres leaving the compacting zone are perfectly parallel and in close contact with one another.
  • Twist is imparted to the round fibre strand without a spinning triangle; through being perfectly embedded, all fibres contribute to yarn strength; there will be hardly any fibres over 3 mm in length that stick out; no fibres are lost in the spinning triangle.
  • Such crushed or reversed fibres as those passing through a condenser will not be found.
