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.

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.

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.

Ence and ShareTex begin initial testing of the ATENEA innovation project to promote textile recycling in Spain

Ence and ShareTex are making progress on the Atenea R&D project, which aims to develop a complete value chain for textile recycling in Spain. Specifically, the goal of the ATENEA project—which is funded by the Center for Technological Development and Innovation (CDTI)—is to connect all the necessary stages for the recovery of textile waste, from collection and management, through recycling and transformation into new raw materials, to their incorporation into new textile products.

DePoly Inaugurates its Showcase Plant in Monthey Switzerland

What if used plastic bottles, PET packaging material and polyester textiles could become raw materials just as high performing as virgin resources? That is the ambition of DePoly, a circular materials company based in Sion, Switzerland which inaugurated its Showcase Plant in Monthey on July 6th & 7th. The first depolymerization facility of its kind and scale in Switzerland, this industrial Showcase Plant represents a major milestone in the company's growth and its journey toward commercialization.

Commission clarifies rules on plastic bottles recycling

The European Commission today adopted new rules on recycling of single-use plastic beverage bottles made primarily of polyethylene terephthalate (PET bottles). These rules establish, for the first time, a methodology to calculate, verify and report chemically recycled content. This is part of the Commission’s December 2025 plastics package.
