The new Pre-Cleaner CL-X: Higher productivity and lower energy consumption

Double the production rate, with lower energy consumption per kilogram of fiber material – that might sound like a contradiction, but the new Trützschler pre-cleaner CL-X makes it possible. It gently and reliably removes coarse contaminants like leaf debris, stalks or seeds from cotton with minimum loss of good fibers. The pre-cleaner CL-X provides more efficiency and lays the foundation for a high-quality end-product before the cotton is further processed in mixers and fine cleaners.

The new CL-X especially meets the urgent demand for lower energy consumption. Energy efficiency is not only important for environmental and regulatory reasons. Due to rising energy prices, it is becoming an increasingly decisive factor for the competitiveness of spinning mills.

"During the development process, our main focus was on optimizing the fiber air flows. This is the area where we achieved the breakthrough. By forcing the air flow over two rolls, we have found a solution that allows lower power consumption at the opening rolls,” says Robert Többen, Head of Mechanical Engineering at Trützschler. “The fact that this flow is in the form of a spiral is also reflected in the name CL-X: The ‘X’ comes from the Greek word for spiral, Helix.”

In comparison with the current benchmark, the CL-X saves up to 30 % energy (see chart 1). In addition to the optimized flow, an integrated air separator contributes to reducing the transport air by ensuring that only excess air has to be removed, rather than all of the air. Less exhaust air means less energy consumption.

The CL-X also provides significantly increased productivity. At a maximum of 1,600 kilograms per hour, the production rate from one CL-X corresponds to the rate achieved by two CL-P models. This gives customers the flexibility to operate at high or low productivity rates with one machine.

On top of this, the new CL-X is characterized by its excellent cleaning results. Trials conducted at a Turkish customer have shown that it reached a nearly three times better cleaning efficiency compared to the benchmark (US cotton, see chart 2). The improved grid geometry enables better separation and gentler tuft handling. Furthermore, a 2.60 m long cleaning section provides a maximum degree of opening and cleaning tufts.

The lot management system enables direct, automated coordination with the Bale Opener BO-P. The speeds of the opening rollers and the position of the grid bars – and thus the intensity of the cleaning – are automatically adjusted to the changing material fed (lot).

Due to the stepless and individual adjustment of grid devices for each opening roller, the machine can react to a wide variety of impurities. A 10 % higher speed of the second opening roller causes different speeds along the grids, while different sizes of waste can also be separated.

The WASTECONTROL waste sensor is now also integrated into the CL-X and makes sure that waste is reliably separated during production, which avoids unnecessary loss of valuable good fibers. The operator automatically receives a recommendation for the ideal setting via the machine's display and can implement it with just a few clicks.

The CL-X is the perfect and sustainable solution to meet today's demand for productivity, cleaning and energy efficiency.

STEELTOP®: A new benchmark in flat tops for spinning preparation

Modern carding generations achieve higher production performance, placing significantly greater stress on flat tops. Higher cylinder speeds and increased fiber density, combined with tighter carding gaps, create more demanding operating conditions. At the same time, poorer raw material quality and the increased use of recycled materials further intensify these challenges. With STEELTOP®, Trützschler introduces a new full steel flat top series developed for these demanding modern carding processes.

Ibrahim Fibres and Trützschler: A strong partnership enters its next phase with the TC 30Si

For more than two decades, Ibrahim Fibres and Trützschler have grown side by side, driven by a shared ambition to continuously improve spinning performance, strengthen technology leadership and set new benchmarks in the textile industry. Today, Ibrahim Fibres is a leading yarn and polyester staple fiber manufacturer in Pakistan. The company operates the largest number of Trützschler cards in the country, with more than 200 machines running across its mills in Faisalabad, and plays an important role in one of Asia’s largest textile industries.

Trützschler’s Integrated Draw Frame IDF 3: Unlocking the full potential of short fiber processing

Spinning mills worldwide are looking for solutions that combine higher productivity, stable quality and shorter processes, especially when processing short fibers. Trützschler’s integrated draw frame IDF 3 has proven to be a powerful answer to these requirements. Evaluations from several customer trials in Türkiye under real production conditions highlight the strong performance of the IDF 3, particularly when combined with the next-generation card TC 30i.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.

Georg Stausberg, CEO of Barmag Group, attended along-side the sales and R&D expert China team to jointly present integrated solutions covering the entire man-made fiber value chain.

Object Carpet tests production of rPET BCF yarn on Neumag BCF line

In a joint project with Object Carpet GmbH, Denkendorf; the Institute for Textile Technology (ITA), Augsburg; and Next Generation Recyclingmaschinen GmbH (NGR), Feldkirchen, Austria, Barmag investigated the processing of recycled polyester for BCF yarn. The goal was to evaluate the fundamental suitability of 100% recycled carpet material for reuse in carpet yarn production to create a closed-loop system in carpet manufacturing. To date, commercial rPET BCF processes have been based solely on rPET from bottle pellets.

New spinning package with two-step filtration for recycled yarns and more

At the ITM in Istanbul, BB Engineering unveiled its new, patented ValuePack spinning package for the first time, which features a two-stage filtration system. This is particularly beneficial for re-cycling processes. Until now, spinning packs have used either metal powder (“sand”) or filter candles as filter media. Both options are suitable for differ-ent applications, and each has its own specific advantages and dis-advantages.
