From the Sector

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.

ACG Kinna Automatic and ACG Nyström – members of TMAS, the Swedish textile machinery association – have delivered the first microfactory for the production of fully finished filter bags to an international filtration industry customer, in cooperation with JUKI Central Europe.

The microfactory’s configuration is based on two separate interconnecting modules – the Smart Filter Line (SFL) and the Filtermaster 2.0. The SFL handles the fabric feeding from rolls and its folding prior to seam construction, which can either be by automatic sewing, welding or with sewing and taping, depending on specifications. Very rapid changeover of the modular seaming methods can be achieved during product changes. The specific size of the now fully-tubular fabric is then precisely cut to size for each individual unit and further folded ready to be fed into the Filtermaster 2.0. The Filtermaster 2.0 then automatically attaches the reinforcement, bottom and snap rings onto the filter tube with a second Juki sewing head on a robotic arm, to form the fully finished filter bag ready for packaging.

Filter bags are employed in a wide range of industrial processes and while they may be largely under the radar as products, they represent a pretty significant percentage of overall technical textiles production.
They are used in foundries, smelters, incinerators, asphalt plants and energy production plants. Other key manufacturing fields – often where dust is generated – include the production of timber, textiles, composites, waste handling and minerals, in addition to chemicals, food production, pharmaceuticals, electronics and agriculture.

As a further example of the scale of the industry and the high volumes of fabrics involved, one supplier has delivered a single order of 30,000 filter bags to be used for flue gas cleaning at a European power plant. The bags can also be anywhere up to twelve metres in length and frequently have to be replaced.

Glen Raven hosted United States Trade Representative (USTR) Ambassador Katherine Tai in an important visit to the company’s yarn spinning manufacturing facility and headquarters for its Sunbrella® flagship brand in Burlington, N.C. followed by an industry supply chain roundtable.

Ambassador Tai’s visit coincides with USTR’s Federal Register notice for public input to inform the administration’s development of trade and investment policy initiatives related to a domestic supply chain resilience plan.

USTR has highlighted domestic textiles as a critical part of the supply chain. The textile sector, which includes yarns, fabrics, apparel and other finished goods, will be part of its fact-finding investigation into shaping policy tools that could be deployed to enhance supply chain resilience. The office is requesting input on policies that are currently working well for these sectors, and those that are not working well, in advancing domestic supply chains.

The Ambassador’s visit to Glen Raven included a tour of the Sunbrella facilities, a design and innovation center, and a roundtable discussion with several other textile executives based in North Carolina who highlighted the significant impact of the sector to the U.S. economy.

Glen Raven, a family-owned company founded in 1880, operates five manufacturing facilities in North and South Carolina employing 2,500 people, including their joint venture with Shawmut Corporation. The company is currently in the process of scaling a $250 million multi-phase U.S. capacity expansion plan of its facilities and infrastructure to meet customer demand.

The Lenzing Group has created an innovative concept that contributes to the sustainable protection of our glaciers while inspiring collective action for sustainable practices and a circular economy in the nonwovens and textile value chain. The concept, which was artistically staged by the Italian artist Michelangelo Pistoletto, was presented on March 21, 2024, as part of the International Day of Forests celebrations at the Palais des Nations, the headquarters of the United Nations Office at Geneva (UNOG).

The melting of glaciers is being severely impacted by global warming. Geotextiles are used to protect ice and snow. However, the nonwovens used for this are made of fossil-based fibers, which allow microplastics1 to enter the valley via streams and may enter the food chain through small organisms and animals. Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

The covering of a small area with the new material made from LENZING™ fibers was tested for the first time during a field test on the Stubai Glacier. Four meters of ice were saved from melting. This was confirmed in a study conducted by the University of Innsbruck and the Austrian glacier lift operators on the Stubai Glacier in Tyrol (Austria). In 2023, the pilot project was successfully extended to all Austrian glaciers used by tourists.

Last year, the project was also awarded first place in the prestigious Swiss BIO TOP Awards for wood and material innovations.

Lenzing takes this innovation project as an opportunity to inspire collaborative action towards sustainable practices and circularity in the textile value chain. Together with a network of innovative partners, Lenzing is working on processing geotextiles into new textile fibers giving them a second life as a garment. The use of geotextiles is usually limited to two years, after which the nonwovens would be disposed of. In the first phase of the pilot project, the recycling of nonwovens made for geotextiles use has been successfully tested and a fashionable “Glacier Jacket” has been produced, showcasing that the recycling of geotextiles is viable. Next to Lenzing, the network includes Marchi & Fildi Spa, a specialist in the field of mechanical recycling, the denim fabric manufacturer Candiani Denim and the fashion studio Blue of a Kind.

The DITF is leading the joint project "DACCUS-Pre*". The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO₂ from the atmosphere than is emitted during its production.       

In collaboration with the company TechnoCarbon Technologies, the project is now well advanced - a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO₂ balance of the material:

Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of stone dust. This is very reactive due to its large specific surface area. Silicate weathering of the rock dust permanently binds a large amount of CO₂ from the atmosphere.

Carbon fibers in the form of technical fabrics reinforce the side walls of the wall elements. They absorb tensile forces and are intended to stabilize the building material in the same way as reinforcing steel in concrete. The carbon fibers used are bio-based, produced from biomass. Lignin-based carbon fibers, which have long been technically optimized at DITF Denkendorf, are particularly suitable for this application: They are inexpensive due to low raw material costs and have a high carbon yield. In addition, unlike reinforcing steel, they are not susceptible to oxidation and therefore last much longer. Although carbon fibers are more energy-intensive to produce than steel, as used in reinforced concrete, only a small amount is needed for use in building materials. As a result, the energy and CO₂ balance is much better than for reinforced concrete. By using solar heat and biomass to produce the carbon fibers and the weathering of the stone dust, the CO₂ balance of the new building material is actually negative, making it possible to construct CO₂-negative buildings.

The third component of the new building material is biochar. This is used as a filler between the two rock slabs. The char acts as an effective insulating material. It is also a permanent source of CO₂ storage, which plays a significant role in the CO₂ balance of the entire wall element.

From a technical point of view, the already realized demonstrator, a wall element for structural engineering, is well developed. The natural stone used is a gabbro from India, which has a high-quality appearance and is suitable for high loads. This has been proven in load tests.  Bio-based carbon fibers serve as the top layer of the stone slabs. The biochar from Convoris GmbH is characterized by particularly good thermal insulation values.

The CO₂ balance of a house wall made of the new material has been calculated and compared with that of conventional reinforced concrete. This results in a difference in the CO₂ balance of 157 CO₂ equivalents per square meter of house wall. A significant saving!

KARL MAYER has already produced a wide range of electrically conductive warp-knitted items for a wide variety of applications in the TEXTILE-CIRCUIT division of its TEXTILE MAKERSPACE, including a sensor shirt, a gesture control system and a conductive charging station. In order to drive the topic of wearables forward, the textile machine manufacturer has signed a cooperation agreement with the Grabher Group and delivered an MJ 52/1-S to the specialist for high-tech textiles in Lustenau. Managing Director Günter Grabher officially inaugurated the key machine for project work in the smart textiles sector in May 2023.

The machine is involved in various research projects, but is also available for new projects and tasks. The smart textiles competence team at KARL MAYER and Grabher is looking forward to supporting the ideas and work of interested parties also outside the research network with its know-how and the possibilities of the MJ 52/1-S.

The MJ 52/1 S is also an extremely flexible project machine. The 138″ model in gauge E 28 produces a wide range of warp-knitted fabrics and incorporates conductive material directly into the textile surface - exactly where it is needed and with the structure that is required. The basis for the tailor-made fiber placement is KARL MAYER's string bar technology. The system for controlling the pattern guide bars ensures a fast, established textile production process and a high degree of pattern freedom.

Archroma has developed a new wet-fastness improver that helps brands and mills produce durable clothing, towels, linens and other textile products with long-lasting colors without compromising on quality or introducing hazardous chemicals.

ALBAFIX® ECO PLUS is a next-generation fixing agent that delivers a strong wet-fastness for all reactive dyes on cotton and other cellulosic fibers and polyester-cotton blends. It will not change the shade of the dyed fabric or negatively impact light-fastness. The product also avoids production challenges – such as foaming, acid hydrolysis and migration problems during drying – to promote efficiency and quality output.

ALBAFIX® ECO PLUS is suitable for jet applications, and for other dyeing and washing equipment with vigorous liquor circulation, and can also be applied by exhaustion, by padding or from the last bath of the soaping process after dyeing or printing.

Like ALBAFIX® ECO, the latest addition to the ALBAFIX® family has a positive influence on chlorine-fastness. When applied with double fixing, it achieves the same high performance on polyamide and PA/Elastane fabrics, as it does on cellulosic fibers. This makes it ideal for the production of swimwear, as well as sportswear and outdoor clothing.

ALBAFIX® ECO PLUS complies with global eco-standards and initiatives, including Global Organic Textile Standard (GOTS), bluesign® and the Zero Discharge of Hazardous Chemicals (ZDHC) Roadmap.
