Oerlikon Segment Manmade Fibers aims to pave the innovative way to the future of BCF technology, with the introduction of the rotating tangle unit RoTac3 at the Domotex 2015 that takes place from 17-20 January in Hanover.

Oerlikon Neumag’s exhibition highlight enables substantial energy savings and creates many further advantages for the production of BCF carpet yarn with the 3-end plant S+, according to the manufacturer.

“The RoTac tangle unit has been the effective solution for the single-end BCF plant Sytec One since 2012. In the meantime, practically all Sytec Ones are sold with the RoTac. However in order to use this technology for our flagship S+, a considerable amount of detailed work was necessary,” commented Mathias Stündl, Head of BCF Development at Oerlikon Neumag.

Production of BCF yarns

The tangling or intermingling plays a decisive part in the production of BCF yarns. Through the tangle knots, loop formations are prevented when tufting and weaving the carpets.

Furthermore, they also define the colour mixtures of tricolour yarns and thus enable a homogenous appearance of so-called tricolour carpets.

Offering the constant increase of productivity respectively, the process speeds implicated increasing demands on the tangling, resulting in higher air pressures and a double tangling unit. 

A further plus for the S+

The new RoTac3 is tuned for the 3-end BCF plant S+. In comparison to conventional tangle units, the RoTac technology forms the tangle knots with a pulsating instead of a continuous air current. The core element of the RoTac is a rotating nozzle jacket, which has several holes with a corresponding spacing according to the required number of knots.

If a hole is positioned over the compressed air opening, an air blast is released and tangles the yarn. Therefore, compressed air is only consumed if a tangle knot is to be formed. The necessary volume flow and therefore the energy consumption are significantly reduced. In comparison to conventional tangle units, the compressed air consumption is reduced by up to 50%.

Therefore, the RoTac3 has been granted the e-save label for particularly energy-efficient and eco-friendly technologies. This principle enables the RoTac³ to generate tangle knots with defined distances and controllable strengths. Tangle dropouts are reduced and downstreaming performance improved, according to the manufacturer.

Also on showcase

Oerlikon Neumag will also be showing the company’s BCF product portfolio, S+ and Sytec One, at the Domotex 2015. The three-end S+ is said to produce high-quality BCF yarns and serve a very wide titer range (600 to 4000 dtex).

According to the company, all polymers, from polyester to polypropylene up to polyamide 6, can be processed on these multi-polymer plants without conversions being necessary, whereby the machine utilizes the applied raw material to 99%.

“Whereas the S+ is convincing for commercial applications, the Sytec One is particularly suitable for the demanding production processes because of the one-end application. With the S+ and Sytec One, we are excellently positioned on the global BCF market and can practically fulfil nearly all the customers’ requests,” said Martin Rademacher, Sales Director BCF.
