More Details

A novel spinning technique named Nu-torque has been developed physically in a single step for producing a low twist and low residual torque singles yarn by introducing a false-twister into the conventional ring spinning frame.

The benefits of Nu-Torque Technology include:

  • low yarn residual torque
  • reduction of yarn twist (18-40%)
  • low yarn twist but high yarn strength
  • soft handle
  • low fabric spirality
  • energy saving
