Mastering the heat in synthetic filament production

Threads made of polyamide, polyester, polypropylene, aramid, carbon, bio-based and many other polymers, categorized as technical yarns and high-performance fibers are a special field of Retech. The Swiss company is the expert in heat treatment and drawing man-made fibers of any material. They present their latest developments at Techtextil Germany 2022 in Hall 12.0, Booth B11.

Retech presents its latest innovations at Techtextil

Identifying a strong demand for technical yarns with maximum strength, Retech addressed this with the newly-launched godet roll, with an ideal length of 420 mm to process eight or twelve threads at a time. Its extended diameter of 250 mm allows a significantly increased speed with the same dwell time. Additionally, the higher motor torque guarantees the very best results in yarn tenacity. Further technical parameters are as remarkable: speed can be ramped up to 6500 m/min and the temperature reaches 250°C with an excellent temperature profile of +/- 1.5 °C.

High-temperature godet rolls are invented for high-performance fibres. Some unique yarn characteristics are made possible by impressive temperatures. High-performance fibres require temperature at extremely high levels, since fibres such as para-aramids have high glass transition temperatures nearing 370 °C. Retech high-temperature godet rolls have a heating power of up to 400 °C. They also offer outstanding performance in terms of precision within 0.5°C – guaranteed by the established Retech temperature controller – and repeat accuracy from 1 to 100 godets.

Retech’s innovations for godet roll temperature management are precise, reliable, easy to handle, and durable. One of these innovations is the temperature transmitter which proves to operate in the harshest electromagnetic environment at highest precision. The system’s key part, the co-rotating sensor fork was recently revolutionized. Latest electronic and new materials compensate for disturbing influences which could tamper with the measuring signal.

Last but not least, the UTL monitoring device analyses the data and integrates it in the communication protocol for perfect data security. The UTL guides filament yarn producers toward Industry 4.0.

50 years of Swiss precision - Retech highlights latest technology to produce high-quality synthetic fibers

High-quality synthetic fiber production requires uncompromising precision and process stability. Godet rolls play a key role in ensuring exact temperature control and maximum reliability. As a Swiss pioneer in thermal treatment for filament fibers, Retech has been setting benchmarks for five decades – with technologies that make production processes smarter, more efficient, and more sustainable.

Retech will present advantages of its leading godet rolls at Techtextil

Godet rolls are essential components in the production of synthetic fibres. These heated, ambient or cooled rolls help achieve the perfect yarn quality for a range of materials and applications when it comes to heat treatment for filament fibre applications. Retech's heated godet rolls are designed to meet critical requirements: delivering precise temperature control tailored to each material and maintaining consistent temperature levels throughout the process.

MUNICH FABRIC START: Between Attitude and Sensuality

The future begins where we reimagine it. After seasons of restraint, Spring.Summer 27 marks a conscious counter-trend: optimism, sensuality, and creative freedom are replacing pragmatism and neutrality. Physical presence and individuality are regaining importance – as a response to uncertainty, exhaustion, and algorithmic predictability. The overarching theme of PLEASURE stands for fashion as an emotional space, as an expression of attitude and cultural reflection. Colours, surfaces, and materials become vehicles for self-confidence and joie de vivre.

organIQ seek: smart alternative to potassium permanganate

CHT Group announces new technical findings within its organIQ seek platform that significantly advance the transition toward permanganate-free denim bleaching. Through extensive industrial testing and application research, CHT confirms that organIQ seek can now be used with remarkable effectiveness as a substitute for potassium permanganate in spray bleach, while remaining aligned with sustainability expectations and cost realities in the European market. At the COLOMBIATEX in Medellín as well as at the Exintex in Puebla and the Kingpins Show in Amsterdam the CHT Group will present organIQ seek as an alternative to potassium permanganate.

PERFORMANCE DAYS: Focus topic shifts to the beginning of the value chain

Following the last Focus Topic in October 2025, which placed Textile-to-Textile Recycling at its core, PERFORMANCE DAYS continues to drive the conversation around circularity – this time with an expanded and more upstream perspective. The upcoming Focus Topic, “Textile to Textile: The Role of Collectors and Sorters,” presented during the spring edition on March 18–19, will spotlight one of the most essential yet often overlooked components of a functioning circular textile system: the efficient collection and sorting of post-consumer textiles.

Proven performance, optimised costs – the new RE 6 EL

Nowadays textile companies increasingly need to produce small production runs and respond to market changes with instantaneous pattern changes in order to operate profitably – meaning they require machines that offer maximum flexibility, reliability and cost efficiency. KARL MAYER understands the challenges of the market and is launching its new RE 6 EL. The Raschel machine offers the core strengths of the classic RSE 6 EL and essentially the same performance parameters, but has been further cost-optimised largely due to local production advantages. This makes the newcomer an efficiency champion in production, especially when it comes to frequent pattern changes.
