Solutions for IDY production - Oerlikon Barmag - Oerlikon Textile

Melt preparation
Extrusion equipment
Oerlikon Barmag spinning extruders excel at gentle and homogeneous
melt production and are noted for cost effectiveness,
reliability, and long service life.
The utilization of top-quality, low wear materials – in particular
for the extruder cylinders and the extruder screw – ensure
long-term, error-free operation. The screw geometries with
special homogenizing components have been engineered
to ensure short dwell times in order to keep the thermal and
mechanical loads of the melt to a minimum – the basis for
excellent melt and hence first-class yarn quality.
Oerlikon Barmag extruders fulfill the e-save energy saving
requirements. The e-save label is awarded to systems and
components that have energy consumptions significantly
lower than standard equivalent systems and components
available on the market.
Oerlikon Barmag extruders are characterized by their excellent
barrel insulation resulting in energy savings and a low
surface temperature on the barrel jacket. The two-step spur
gear guarantees long service life and smooth running. The
feed area for inert gas or vacuum is designed to prevent
oxidation of the polymer, thus ensuring trouble-free spinning.
Specially matched screw and barrel materials result in good
sliding properties and low wear.
26 IDY solutions – Oerlikon Barmag
Air-cooled extruder series
These are the perfect choice for processing PETP, PA6,
PA66, PP and other spinning polymers in all viscosity ranges
for all manmade fiber requirements.
An optional feature offered is the control cabinet, which is
integrated into the extruder frame. This version transforms
our well-established model into a compact unit with significantly
less wiring.
All versions are available with or without a cooling system for
the barrel. An injection system introducing master-batches
or liquids into the polymer stream at various locations for
customized fiber characteristics is also available.
The extruder series ranges from 90-mm to 175-mm screw
diameter and a throughput range from 40 kg/h to 720 kg/h.
Direct spinning
Cost competition in the IDY sector is also increasing. Therefore,
especially for high capacity installations/plants, the
direct spinning technology is becoming more and more
attractive. Some of the latest Oerlikon Barmag IDY lines are
already operating successfully in a direct spinning process of
this kind. For this technology, Oerlikon Barmag can engineer,
design and provide the complete system for high IV melt
distribution.
