From the Sector

Freudenberg Performance Materials (Freudenberg) is showcasing solutions for the automotive, building, apparel, filtration and packaging industries at this year’s Techtextil in Frankfurt am Main from April 23 – 26.

Sustainable nonwoven for car seats
One innovation highlight at Techtextil is a novel Polyester nonwoven material for car seat padding. Also available as a nonwoven composite with PU foam, it is not only easier for car seat manufacturers to handle during the mounting process, but also ensures better dimensional stability as well as providing soft and flexible padding. It has a minimum 25 percent recycled content, for example, by reusing nonwoven clippings and waste, and is fully recyclable. Full supply chain transparency enables customers to trace and verify the content of the nonwoven and thus ensures a responsible production process. The Freudenberg experts will also be presenting several other nonwoven solutions made of up to 80 percent recycled materials that can be used in car seat manufacturing.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

Freudenberg Performance Materials (Freudenberg) is extending its recently-introduced ECO range of sustainable nonwoven carpet backings: Lutradur ECO-R and Colback ECO-R backings contain high percentages of recycled raw materials. With its ECO portfolio Freudenberg supports carpet manufacturers in their transition towards an increasingly sustainable product offering.

The company launched its ECO range for sustainable primary backings earlier this year with the introduction of the ECO-RE resource-efficient backings that use less raw materials and support end product recyclability. To achieve this, Freudenberg R&D teams further developed the company’s proprietary yarn production technology allowing for extremely thin filaments.

ECO-R products
Freudenberg’s spunbond nonwoven primary and secondary carpet backings contribute to manufacturers’ easy and efficient production processes as well as to high-performance end products. The company is now extending its ECO range in Europe with Colback ECO-R and Lutradur ECO-R backings that contain a recycled content of between 51 and 90%. Replacing virgin raw materials with recycled polyester saves on natural resources and improves the carbon footprint of end products. The ECO-R backings are specifically suitable for carpet tiles, broadloom, dust control mats and automotive option mats.

Nylon 6, nylon 6,6, polypropylene, PET and calcium carbonate are available through the company’s proprietary carpet recycling process

Circular Polymers by Ascend, a market-leading recycler of post-consumer carpet, today the launch of Cerene™, a line of recycled polymers and materials made from the company’s proprietary carpet reclaiming technology. Cerene is available as polyamide 6 and 66, PET, polypropylene and calcium carbonate as a consistent,
sustainable feedstock for many applications, including molding and compounding.
Recycling experts from Circular Polymers will be showcasing Cerene at Compounding World Expo on June 14-15 at the Messe Essen in Germany.

Ascend Performance Materials, a fully integrated producer of durable high-performance materials and the majority owner of Circular Polymers by Ascend, is known for its innovations in nylon 6,6. Cerene will continue that legacy with offerings in nylon 6,6 while also bringing to market recycled polymers such as nylon 6, PET and PP.

“Customers around the globe are seeking consistent and reliable post-consumer recycled materials,” said Maria Field, business director of Circular Polymers by Ascend. “Cerene is mechanically recycled using a process that minimizes our carbon footprint and environmental impact.”

Circular Polymers by Ascend converts post-consumer carpet into fiber and pellets. The company uses a proprietary process in its California-based facilities to achieve high efficiency in recycling, successfully providing a new life for virtually every component of the carpet and backing. The company has redirected 85 million pounds of carpet from landfills into new goods since 2018.

Freudenberg Performance Materials (Freudenberg) announces the launch of sustainable carpet backing products for the flooring industry. Sustainable backings support customers in their transition towards producing more sustainable carpets. The range is introduced as Colback ECO and Lutradur ECO and is part of the Freudenberg portfolio of high-performance spunbond nonwoven technical textiles.

Reduced CO₂ footprint
Freudenberg follows a ‘less is more’ principle: the best raw materials are the materials that are not needed at all. For the ECO product range, Freudenberg R&D teams developed a solution to save raw materials in their carpet backings. Freudenberg redefined its proprietary yarn production technology allowing for extremely thin filaments with a diameter up to 30% smaller than the standard portfolio for carpet backings.  
The new thin yarn technology is one of Freudenberg’s sustainable initiatives benefitting the carpet industry. Other developments supporting sustainability include backings with a high recycled content and backings using alternative approaches to facilitate carpet recyclability. They will extend the ECO portfolio in the future.

ECO-CHECK-Label
The currently launched thin yarn ECO-backings have been awarded the ECO-CHECK label. Freudenberg introduced this label in early 2021 to identify particularly sustainable products within its portfolio.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

As an accredited testing and certification body, the “OETI - Institut fuer Oekologie, Technik und Innovation GmbH“ (OETI for short) has been successfully responding to prevailing market requirements for 55 years and, in the process, has made a name for itself worldwide. To mark its anniversary, this international centre of excellence with its origins in Austria is taking a look back at the most important milestones in its history as well as providing interesting insights into future developments.

As renowned flooring manufacturers founded the Austrian Carpet Institute on 25th of September 1967, no one could have imagined how successful the company would become. But even back then, one thing was clear to the experts: the need to establish a carpet research and testing centre in the form of an association. Today, over five decades later, OETI is a testing and certification services provider for OEKO-TEX® certificates and labels, textiles, leather, due diligence along the textile and leather supply chain as well as for personal protective equipment (PPE), flooring technology, furnishings and indoor air quality.

In 1992, OETI was a founding member of the ‘International OEKO-TEX® Association for Research and Testing in the Field of Textile and Leather Ecology’ with independent certifications and product labels. Ever since, OEKO-TEX® has enabled companies along the textile and leather supply chain and every consumer to make responsible decisions for safe, environmentally friendly and fairly manufactured products.

In line with its focus on sustainability, OETI and its Swiss parent company, TESTEX AG, wanted to build the new OETI headquarters using low energy construction techniques and ensure its carbon-neutral operation. To achieve these goals, the highest possible thermal insulation and energy optimisation standards were applied, while the carbon-neutral power supply is generated by its in-house photovoltaics system as well as domestic renewable energy.

The new headquarters, which the company moved into in 2021, provides space for 75 employees over 2,500m2 and boasts bright and perfectly equipped office areas. The laboratory areas, the analytical/chemical laboratory and the physical / fire laboratory were also designed based on the latest methods and technologies. This makes OETI, alongside its Swiss parent company TESTEX, the second fully fledged laboratory site in the entire, global TESTEX Group.

BB Engineering GmbH (Germany) delivers a melt filter for recycling PET flakes to polyester manufacturer Indorama Polyester Industries (Thailand). Indorama will be using the type NSF38 filter in its recently assembled recycling system in order to produce rPET granulate from flake PET bottle waste. The NSF38 filter enables continual filtering – in other words, the system switches from one filter to the other during the process without the need for conversion shut-downs. The filter allows the processing of consumer waste for example, in the form of shredded PET bottles into new, high-quality rPET granulate. This granulate is subsequently processed into manmade fibers in spinning systems.

The NSF38 is a switchable filter with a filter surface area of ap-prox. 16 m2 on each side, with throughputs of between 1,000 and 1,900 kg/h. The filter inserts each contain 19 pleated filter candles (60 x 1,000mm Ø). The filter medium comprises a sin-tered metal fiber nonwoven with a filtration fineness of 25 μm. This ensures that the melt remains free of contaminants and gel particles, which in turn enables the production of high-quality end products.

AMUT’s strategic partnership with EREMA contributes to accelerate the transition towards a greener world.  In summer 2021, EREMA in collaboration with AMUT  has finalized the installation and commissioning of ALTO packaging ́s first extrusion line for food grade PET sheets in New Zealand market. At the ALTO Plastic Packaging site, in Albany, the plant now processes 100 % washed post-
consumer flakes into 100 % food contact grade monolayer thermoforming sheet. In New Zealand, this milestone represents the first system to be installed for this special application.

The plastic packaging company ALTO, a division of PACT Group, invested for this new food grade PET sheet extrusion line as a part of Pact Group ́s vision to lead Circular Economy through Packaging in Australia and New Zealand.

Thanks to the direct combination of VACUREMA® PET recycling technology and the AMUT Inline Sheet production technology there is no longer any extra process stage. This is, because the melt goes straight from the VACUREMA® 1716 T Basic to the AMUT plant without the detour of pelletising. The post-consumer PET material is already decontaminated and pre-dried prior to extrusion in the vacuum reactor of the VACUREMA® Basic, with a throughput of up to 1,500 kg per hour. After high capacity filtration by EREMA SW-RTF backflush filter and online IV measurement, the melt goes directly into the AMUT Inline Sheet plant where it is processed into thermoforming sheet from 0.15 mm till 1.2 mm thickness. The monolayer thermoforming sheet produced from pure rPET is not only 100 % food contact compliant, it also fulfils the FDA and further regulations. At ALTO it is further processed into trays and food containers.

AMUT played its part by providing a full range of downstream equipment ranging from the Automatic Tdie, three rolls stack calender with automatic gap control and motorized cross axing unit, lamination unit for welding and barrier films, thickness control gauge to anti-static silicon coating unit, fully automatic two shafts turret winder and in line edge trims grinding and recycling.

The special features of this extrusion line come from the complete automatic and easy management of the line. This is due to the new Amut`s software including the Easy Start and Easy Change functions that will allow the operator to start the extrusion line and change product formats in automatic mode.

EREMA and AMUT are long-term partners in the Inline Sheet sector. EREMA ́s VACUREMA® technology is currently in use in more than 100 Inline Sheet facilities around the world, also for PACT Group companies in Australia.
