Oerlikon Neumag promised more flexibility in the color pattern design of carpets with the latest carpet yarn system BCF S8 at DOMOTEX 2020 in Hanover.
Multi-colored carpets are becoming increasingly popular and the desire for significantly more flexible color mixing variants for product differentiation is increasing. Oerlikon Neumag has focused on this and developed the BCF S8, a platform that leaves nothing to be desired when it comes to the color separation of tricolor yarns.
Over 200,000 different shades out of three colors
The core component in this process is the new, patent-pending Color Pop Compacting Unit (CPC-T) for an even more flexible and even color separation. Individually controllable air pressures per color in the CPC-T provide a pre-tangling, which results in an accentuation of the colors and thus enables over 200,000 different shades.
Color Pop Compacting also for PA6 yarns
Until now, it was difficult to produce highly color-separated or accentuated BCF yarns from polyamide 6, but in the future, this will be possible thanks to the CPC-T. Thanks to the new design, the CPC-T is now also suitable for processes with low thread tensions.
RoTac³ tangle unit with extensive modifications
Significant technological changes to the RoTac³ tangle unit lead to even more efficient BCF yarn tangling. On the one hand, the nozzle has been optimised flow-wise so that the air pressure can be reduced by approx. 10% compared to the previous version with the same knot strength. Furthermore, the nozzle bearing arrangements have been improved. As a result, either higher speeds or nozzle rings with a higher number of holes can be driven, which results in even more knots in the yarn.
The RoTac³ is part of the standard scope of delivery for the newer BCF S8. The tangle unit is optionally available for the single-thread Sytec One plant as well as for the three-thread S+ and can be retrofitted on request.
Oerlikon Manmade Fiber solutions for PET carpet applications now cover a range from 0.5 to 30 dpf
In addition to the BCF S8 technology described above, Oerlikon Manmade Fibers offers another system concept based on a POY and texturing process. This configuration is designed for a carpet and home textile product range, which is based on a very soft and puffy polyester thread with BCF-like properties due to the small dpf. The target is yarns with a titer up to a maximum of 1300dtex and typically over 1000 filaments. Typical products are, for example, a 1300dtex f1152 or 660dtex f1152 and 990dtex f768. The machine concept consists of the well-known WINGS HD POY winder and the new eAFK Big-V texturing machine.
Oerlikon Nonwoven showcases convincing meltblown and spunbond technology
The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA, taking place between February 26 and 28.
Meltblown technology for filtration applications
Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam. Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.
Electro-charging for superior filter separation performance
The filter efficiency can be considerably increased by means of so-called electro-charging – where the nonwovens are electrostatically charged. With its extreme flexibility when charging the most diverse nonwovens, the Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.
Spunbond technology for filtration applications
And spunbonds are frequently also being deployed in liquid and air filtration. Here, the nonwovens are predominantly used as carrier materials in order to provide both filter stability and the necessary pleatability. Furthermore, they are also deployed as preliminary filters in automobile and HVAC applications (heating, ventilation, air conditioning).
It is in this area that Oerlikon Nonwoven stands out with its segmented spin packs, which guarantee even melt distribution and polymer dwell time. The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.
