Bicomponent Technology

The Oerlikon Neumag spunbond lines can be equipped with Neumag Bicomponent Technology.  

Two extruders are used to melt the different polymers which are fed to the spinning pumps integrated in the spinning beam. The two polymers are distributed via a segmented distribution system minimizing shear stress and are combined to a bicomponent fiber in the spin pack.

Sheath-core is the most common fiber type in the nonwoven industry. The unique Neumag Bicomponent System allows a sheath content as low as 5% creating considerable advantages:

  • exellent bonding of fibers with PE surface
  • good bonding against PP meltblown in SMS fabrics providing superior softness
  • recycling of waste into core polymer stream possible due the very low amount of sheath polymer in the waste.
