RoTac³ tangling unit with comprehensive modifications

Major technological changes to Oerlikon Neumag’s RoTac³ tangling unit produce even more efficient BCF yarn tangling. On the one hand, the tangling nozzle has been flow-optimized, allowing the air pressure to be lowered by approximately 10 percent compared to its predecessor, while maintaining the same knot strength. Furthermore, the nozzle bearing arrangements have been improved. Consequently, either higher speeds or nozzle rings with greater numbers of holes can be used, generating more knots in the yarn.

Efficient BCF yarn tangling

Even at high production speeds, tangling knots can be set considerably more evenly with the RoTac³ than in the case of other conventional tangling units. Frequent tangling dropouts are now a thing of the past. This ensures better yarn quality and has a positive impact on further processing. The result: the carpet has a visibly more even appearance.

Stable and efficient yarn production is hugely important to yarn manufacturers. Not only does the evenness of the tangling knots make the investment interesting, so too does the energy efficiency of the RoTac3. The tangling unit requires up to 50 percent less energy for generating compressed air. Against the background of rising energy prices, this represents an excellent prerequisite for optimizing production costs.

Oerlikon Neumag has been able to secure various retrofit contracts since the launch of the RoTac3 in 2015. And new systems are predominantly equipped with RoTac³. The RoTac³ is included in the standard scope of delivery for the newer BCF S8 system. The tangling unit is available as an option both for the single-end Sytec One system and the three-end S+ and it can also be retrofitted on request.

Even more efficient and economical – the modified RoTac³ is part of the BCF S8’s standard scope of delivery (c) 2020 Oerlikon

Oerlikon Manmade Fibers Solutions hosted successful Technology Day 2025 in India

Oerlikon Manmade Fibers Solutions recently hosted its highly anticipated Innovation and Technology Day at the Deltin Hotel in Daman by end of January 2025. The event attracted over 300 participants, including industry experts, partners, and stakeholders, who gathered to explore the latest advancements and trends in the manmade fibers industry in India.

Oerlikon reports third quarter 2024 results, highlights strong execution in a challenging market landscape

In the third quarter of 2024, Oerlikon reported a stable operational Group EBITDA margin, despite challenging market conditions, thanks to a focus on pricing, cost management, and efficiency across both divisions. Group order intake saw a 4% year-over-year decline at constant FX, attributed to temporary market softness in Surface Solutions, while orders in Polymer Processing Solutions showed signs of stabilization.

Temco launches a new DTY all-in-one solution

Temco introduces the DTY All-in-One Solution – a fully harmonized set of components engineered to give customers a highly stable, low maintenance and reproducible process environment. The solution reduces interruptions, extends component lifetimes and supports consistent yarn quality across all machine positions. All-in-One Solution – a fully harmonized set of components engineered to provide maintenance and reproducible process environment.

DIENES at Techtextil 2026: Flexible pilot lines for bio-based fiber development

The growing relevance of bio-based materials in technical textiles is accompanied by increasing demands for reproducibility, high-quality data, and scalable process routes. Especially when working with cellulose and its derivatives, chitosan, lignin-based approaches, or bio-based PAN as a carbon-fiber precursor, R&D teams face variable feedstock quality, tighter process windows, and the need for reliable comparability across trials. This calls for flexible, data-driven experimental setups that can be reconfigured efficiently when recipes, solvents, and raw-material batches change.

RETECH showcases high-precision godets for high-performance fiber processing at Techtextil 2026

RETECH designs and manufactures godets and draw frames for heated, ambient and cooled processes, enabling precise heat treatment and consistently high yarn quality for a wide range of polymers and applications, with process temperatures of up to 400 °C for high-performance fibers. The company’s key competence lies in exact and stable temperature and speed control, individually adapted to the specific material and process requirements.

New study shows low environmental impact by Cotton made in Africa Organic Cotton from Tanzania

Today, the Aid by Trade Foundation (AbTF) is announcing the results of a comprehensive life-cycle analysis (LCA) for cotton produced in Tanzania under the Cotton made in Africa Organic (CmiA Organic) standard. The study emphasises the small ecological footprint of CmiA Organic verified cotton. This can largely be traced back to the absence of synthetic pesticides, artificial fertilisers, and artificial irrigation. Consequently, CmiA Organic cotton can help the textile industry meet regulatory requirements as well as science-based targets. The results also show that the consequences of climate change threaten the livelihoods of these cotton farmers, even though the type of agriculture they practise barely contributes to climate change.

PERFORMANCE DAYS proves its relevance as the industry’s key meeting point

Held on March 18–19, 2026, PERFORMANCE DAYS once again confirmed its position as a leading international platform for functional textiles. A total of 3.366 trade visitors and around 560 exhibitors gathered in Munich, with the event already kicking off successfully on DAY 0, which received highly positive feedback for its interactive format. Despite challenging conditions caused by the public transport strike in Munich, the event saw strong attendance and a consistently high level of activity across both exhibition days.
