From the Sector

Freudenberg Performance Materials is introducing Freudenberg Friction Inserts to trade visitors at WindEnergy, the leading trade fair for the international wind energy industry. Freudenberg Friction Inserts is a unique technology aimed at increasing the power density of wind turbines.

The Freudenberg Friction Inserts (FFI) technology is based on a special very thin nonwoven carrier material coated on one side with hard particles. The FFI are customized to fit each application, in terms of both the geometry and the construction parameters of the connection. As they do not create a gap they can be applied exactly where they are needed.

When placed in the joint, these hard particles penetrate into the surfaces of the two joining parts creating a micro interlock, thus reliably increasing the friction coefficient and achieving higher torque transmission in connections. This results in higher performance and a significant improvement in the efficiency of wind turbines. In addition, it enables the downsizing of components without compromising performance, reducing weight and material.

FFI help to improve the reliability of connections and thus of the entire wind turbine. Furthermore, they eliminate slipping and prevent fretting of connections.

Other examples of applications for FFI are highly loaded flange connections between the rotor shaft and gearbox, connections between the main bearing and the machine carrier housing, the gearbox to generator, or at the pitch gear or ring gear. They increase the friction co-efficient between two components.

International technology group ANDRITZ will be presenting its nonwovens production solutions at CINTE 2022 in Shanghai, China – one of the main trade fairs for technical textile and nonwoven products in Asia. ANDRITZ will show its product portfolio covering state-of-the-art nonwovens and textile production technologies such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing.

ANDRITZ supports nonwovens producers in the move to sustainability with the aim of reducing or eliminating plastic components while maintaining the high quality of the desired product properties. This applies to all types of sustainable wipes, such as flushable, biodegradable, bio-sourced, carded pulp or standard carded wipes. The latest development in this field is the ANDRITZ neXline wetlace CP line, which integrates the carded-pulp (CP) process. This is a fully engineered production line combining the benefits of drylaid and wetlaid technologies to produce a new generation of biodegradable wipes.

The neXline wetlaid aXcess targets smaller and medium production volumes and has been devised for new and existing lines. The line is easy and fast to ship due to the compact design, which also fits perfectly into containers. An operator-friendly configuration and versatile design ensure efficient production at affordable investment costs.

The aXcess range was specially developed at ANDRITZ (China) Ltd. Wuxi Branch to handle medium capacities. The facility in Wuxi has an experienced platform for production and service specially geared to serve the Asian nonwovens industry. With the aXcess range, ANDRITZ has developed a hybrid line combining European and Chinese machines, which is the ideal combination to obtain the best added value from each component in the line and be very flexible to accommodate different business cases.

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces of certain materials at different temperatures within a single pass through the machine.

To achieve this, the first two chambers of the stenter are fitted with special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

International technology group ANDRITZ has established a new inline Wetlace™ CP pilot line with an original design at its center of competence in Montbonnot, France. The line combines both spunlace and wetlaid technologies.

From now on, partners will be able to conduct trials and test all options available for wipes production – from carded staple fibers to pulp and various combinations thereof. The combination of both spunlace and wetlaid technologies offers to move forward to more sustainable options while maintaining a high level of product quality, in particular by achieving high CD strength and good linting properties.

Over the past few decades, ANDRITZ has continued to innovate with various nonwoven processes, like spunlace, WetlaceTM and Wetlace™ CP, with the aim of optimizing the use of raw materials and focusing on sustainability by reducing the synthetic fiber content. Facing the growing demand for bio-wipes in parallel with enforcement of the EU’s single-use plastics directive last year, ANDRITZ has decided to support its customers making their investment decisions.

The Montbonnot pilot line has been rebuilt to integrate the new headbox inside the spunlace line. Pulp can be fed in directly and entangled with carded staple fibers to produce unique nonwoven fabrics designed for end uses as bio-wipes.

The viscose specialities manufacturer Kelheim Fibres has won the Techtextil Award in the "New Concept" category for their project "Cellulose-based nonwovens for highly absorbent reusable products".
This award is intended to make cutting-edge developments visible, promote unconventional thinking and intensify the dialogue between researchers, manufacturers.

The starting point for the innovation was the search for a washable and thus reusable absorbent pad made of completely bio-based materials for the cloth diaper of the Berlin-based start-up Sumo.
Two main requirements of the application are obvious: A fast and efficient liquid distribution and high absorbency should minimise rewetting and leakage. Both are ensured by speciality viscose fibres from Kelheim, which have been making this essential contribution to absorbent hygiene products such as tampons for many years. The obvious solution was therefore to optimally utilise the synergies between knitted and woven structures with nonwovens.

In doing so, the advantages of nonwovens in combination with speciality viscose fibres in terms of absorbency (through e.g. more open-pored structures) have been perfectly transferred from the field of disposable to the world of reusable products. For reusable products, however, there is another challenge to overcome: they must remain stable during washing and over several cycles of use. To ensure this, an innovative nonwoven construction was developed in close cooperation with the STFI. These nonwovens can be used as a stand-alone solution or integrated into a textile structure.

Freudenberg Performance Materials (Freudenberg) is endorsing further sustainable products with its ECO-CHECK label introduced last year. These products comply with various environmental criteria. With immediate effect, five more solutions bear the label making the company’s commitment to sustainability visible.

Leather goods
The newly-endorsed ECO-CHECK products include one Evolon® microfilament textile application. This is a reinforcement material for leather goods that is manufactured with no solvent and no binder. It contains up to 80 percent recycled PET and is suitable for a broad range of applications. The material is produced at Freudenberg’s facility in Colmar, France, where the manufacturing process is highly sustainable: it is certified to STeP by OEKO-TEX® and fully complies with the DETOX TO ZERO by OEKO-TEX® criteria.

Healthcare applications
In the field of healthcare, the bio-based M 1714 wound pad with superior absorption for more challenging wounds has now been endorsed with the ECO-CHECK label. The dressing consists of a mix of bio-based fibers derived from natural sources and exhibits a smooth wound contact layer. The product has been evaluated for industrial compostability and conforms to ISO 13432.

Architectural applications
The sustainable TF 400 Eco F mesh fabric for textile architecture from Mehler Texnologies® now also bears the ECO-CHECK label. Its yarn is made of 100% recycled PET bottles and its characteristics are very similar to those of conventional mesh fabrics. In 2021, it was awarded first place by the Architectural Membrane Association (AMA) in the “product” category in recognition of its properties.

Shoes
In the shoe industry, the binder-free strobel insoles have been endorsed as particularly sustainable. They contain a high percentage of recycled green bottle flakes. Moreover, the insoles themselves are fully recyclable.

Filtration applications
The two layered, needle-punched nonwoven filter medium that has just been endorsed with the ECO-CHECK label has impressive sustainability characteristics. Made entirely of polyester, more than half the fibers consist of recycled material.

Trützschler Nonwovens & Man-Made Fibers GmbH started a cooperation with the Italian textile machinery manufacturer Texnology S.r.l. in the field of needle-punching technology. With immediate effect, the companies will offer complete production lines for needle-punched nonwovens under the name of T-SUPREMA.

Web bonding with steel needles represent the largest production process in the drylaid nonwovens segment. The areas of application are predominantly of a technical nature, with the largest applications being durable geotextiles, automotive textiles and filter media. The high adaptability of the needling and finishing processes as well as the broad material base result in a large number of different end products. Needle-punching is suitable for a wide range of man-made and natural fibers including mineral and high-performance fibers.  

Trützschler Nonwovens contributes its many years of experience in fiber preparation and web forming to the cooperation. Texnology is mainly responsible for the needle-punching process. Joint projects can thus build on a broad application expertise.

A first joint project has already been successfully completed, implemented and put into operation.
