Spinning head series SP8x First-class spinning heads make first-class yarns make first-class profits! The quality of the thread is determined during spinning. The manifold in an Oerlikon Barmag spinning line is specially optimized regarding melt residence time, drop in pressure and shear rate. It is characterized by: - flow-favorable melt distribution for excellent yarn uniformity along the spinning line; - high surface quality of the pipes ensures favorable melt flow behavior for superior quality right from the first day of production; - absolute dead spot-free design is a precondition for low break levels and high yields; - the overall distribution system is virtually maintenancefree. Oerlikon Barmag’s spinning head series covers the processes for textile and industrial yarns as well as home textiles even for processing critical materials like PA6.6 and new materials like PTT. In all cases the spinning head steam heating ensures excellent temperature uniformity. e-save with SP8x The Oerlikon Barmag SP8x spinning head concept unites the advantages of high-end melt quality. The design of the spinning head has considerably reduced the heat-radiating surface and simultaneously significantly improved the insulation. This has resulted in a more than 40% reduction in the heat-radiation in comparison to the SP5x system. In trials, this has revealed, for example, energy savings of more than 200,000 kWh/year for a 36-position system. 22 POY solutions – Oerlikon Barmag The SP8x spinning head ensures economic spinning processes with high product quality through its very even melt guidance system with optimized residence time. Furthermore, the shroud – which can be specifically adapted to the respective product on request – ensures an extremely high level of flexibility. The shroud is part of the heat transfer medium (HTM)-heated spinning head and guarantees extremely high temperature evenness without the additional energy requirements of an electrically-heated concept. This system also enables the production of microfilaments without loss of quality and productivity and excellent productivity for standard titers. Needless to say, the well-known self-sealing Oerlikon Barmag spin packs can also be used for this system. The rheologically-optimized melt distribution and uniform heating ensures that the good melt quality in the spinning head is also continued within the spin pack. Reduced spacing with zigzag In combination with the EvoQuench radial inflow quenching unit in zigzag layout, the SP8x is also available in a zigzag design. The reduced spacing in comparison to a standard EvoQuench and SP8x spinning head allows for a higher number of spin packs or bigger packs in the same position pitch. This option is available for 88 and 104 mm spin packs.
Spin packs Advanced spin pack Through continual further development of the spin packs, the spinneret surface has been increased by up to 25% while maintaining the same external dimensions. The throughput required for the spinning process can hence be achieved with a smaller spin pack diameter. The spinning head melt residence time reduces by 10%. The new design offers the following process benefits: - increased filament distance on spinneret for better filament cooling and fewer yarn breaks, especially for microfiber and high count; - large filter surface for higher throughput, compared to other spin packs with the same outer spin pack diameter; - large filter surface for longer spin pack operation time; - increased filament count (microfiber) compared to other spin packs. The advanced spin pack is available as the proven self sealing version, however, for the production of polyamide 6.6 we supply a forced sealing version. Double-in-one When looking at throughput, POY systems for small titers require a relatively high level of investment. The 20-fold Double-in-one (DIO) spinning plant concept has been able to considerably reduce the investment costs while maintaining yarn quality. The DIO concept, with two completely-independent spinnerets in one base, allows manufacturers to use approx. 30% less space vis-à-vis single packages while retaining the titer evenness. Microfilaments with 20 ends can be efficiently manufactured if the DIO technology is combined with the EvoQuench system. Even yarn specialties can be economically manufactured with the optimal combination of DIO and quenching system. With two independently-operated take-up units and the systematic separation of the respective five DIO spinnerets within the quenching system and spin stack, each position is completely independent of the neighboring position in the same spinning head in the event of yarn breaks. This is evident in the fact that 20-end concepts can achieve full package rates which are the same as those for 10-end processes. POY solutions – Oerlikon Barmag 23
