R 441 STR

The R 441 STR machine is designed for continuous twisting / stabilizing of polyamide and polyester stretch yarns wound on very soft cheese and muff package for direct dyeing.

The continuous twisting and stabilizing for the stretch yarn to be dyed is of particular interest because of the lower cost and waste, the greater uniformity and the fewer operations than the “cheese dyeing + twisting process”. This machine can be equipped with spindle type NT 220 and NT 260. The range of shrinkage, in accordance to the texturizing process features, inside the heater goes from 15% to 65%, allowing the following effects:

  • Increasing of yarn softness
  • Increasing of yarn bulkiness
  • Setting and stabilizing of yarn elasticity
  • Increasing of final count
