Oerlikon Barmag makes the mother yarn process profitable

Chemnitz, Remscheid, June 1st, 2016 – in conjunction with the WinFors winder, the Oerlikon Barmag spinning system configuration, designed especially for manufacturing mother yarn, guarantees profitable mother yarn production. The monofilaments produced from this are also extremely convincing in terms of their excellent yarn quality. The perfectly coordinated steps – from the spinning process all the way through to take-up – ensure optimum results in the subsequent, downstream splitting process. 
When manufacturing mother yarn made from polyester (PET) or polyamide (PA) – the preliminary product for monofilaments – the later separation of the filaments must be monitored even during the spinning process. The yarn guide and take-up are attributed a central role: a good splitting process is dependent on the yarn path within the draw unit and the package build.
For this challenging PET or PA process, Oerlikon Barmag technology provides the necessary precise and gentle yarn handling. The spinnerets and quenching unit – whose design has been especially tailored to the requirements of mother yarn – prepare the evenly-cooled filaments for further processing by the system. A special yarn guide in the system supports successful splitting of the yarn. For take-up, the yarn is transferred to the WinFors winder, which has been developed specifically for sensitive yarns. Its cam shaft guarantees excellent package build and stable edges for packages even in the case of the critical, high single dpf in mother yarn filaments. The precise and gentle yarn displacement of the cam shaft concept in conjunction with the tried-and-tested Oerlikon Barmag ribbon breaking process ensures that the downstream splitting process is carried out efficiently and without any loss of yarn quality.
The Oerlikon Barmag FDY mother yarn concept has been optimized for the typical monofilament thicknesses of 15, 20 and 30 dpf and the associated mother yarn types such as 180 den F12, 240 den F12 and 360 den F12. Proven components are deployed: from the extrusion unit, the type SP8 spinning system with its special design and long quenching unit for high single filament titers all the way through to the FDY draw unit with 4 godets (PET) or with 5 godets (PA).
