Oerlikon Neumag promises more flexibility in the color pattern design of carpets with the latest carpet yarn system BCF S8 at DOMOTEX 2020 in Hanover. All trade fair visitors can convince themselves of the possibilities for product differentiation in Hall 11, Booth A36.
Multi-coloured carpets are becoming increasingly popular and the desire for significantly more flexible colour 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 colour separation of tricolor yarns – from mélange to strongly separated.
Over 200,000 different shades out of three colours
The core component in this process is the new, patent-pending Colour Pop Compacting Unit (CPC-T) for an even more flexible and even colour separation. Individually controllable air pressures per colour in the CPC-T provide a pretangling, which results in an accentuation of the colours and thus enables over 200000 different shades.
Color Pop Compacting also for PA6 yarns
Until now, it was difficult to produce highly colour-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.
