From the Sector

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.

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.

• Finnish fashion and textile technology company Infinited Fiber Company plans to build its first commercial-scale Infinna™ fiber factory at Stora Enso’s Veitsiluoto industrial site in the city of Kemi in Finland’s northernmost region of Lapland. Infinited Fiber Company plans to convert a building currently housing a discontinued paper production line.
• The size of Infinited Fiber Company’s planned investment is around EUR 400 million.
• The planned factory is expected to create around 270 jobs at the Veitsiluoto industrial site.
• The factory is expected to operate at full capacity in 2025.

Fashion and textile technology company Infinited Fiber Company plans to build a commercial-scale factory to produce regenerated textile fiber for the world’s leading apparel companies at the site of renewable materials company Stora Enso’s closed Veitsiluoto paper mill in Kemi, a Finnish city on the northern shore of the Baltic Sea. The size of the investment is estimated at EUR 400 million, and it is expected to create around 270 jobs in the area. The annual fiber production capacity of the planned factory is expected to be 30,000 metric tons, which is equivalent to the fiber needed for about 100 million T-shirts.  

Infinited Fiber Company’s technology enables cotton-rich textile waste to be transformed into a versatile, high-quality regenerated textile fiber called Infinna™, which looks and feels like cotton. Major international fashion and apparel companies – including Zara’s parent company Inditex, PVH Europe, which is known for the Tommy Hilfiger brand, Patagonia, PANGAIA, H&M Group and BESTSELLER – have already committed to Infinna™ purchases through multi-year agreements as they look for materials that enable the industry to shift towards circularity. Infinited Fiber Company expects to export most of the output of its planned factory. This makes Kemi an ideal location as the city’s port serves as an efficient link to the rest of the world.

Infinited Fiber Company will convert a building housing a discontinued paper production line into an Infinna™ fiber factory. Both the factory engineering and project implementation as well as the related financing negotiations were commenced at the beginning of the year and are progressing well. Infinited Fiber Company has also agreed on the provision of energy and water related services with utility infrastructure company Nevel.

Once up and running, the factory is expected to provide direct employment for around 220 people, and for a further 50 through on-site support functions such as services, maintenance, and logistics. The additional indirect employment impact is estimated to be around 800 jobs. The construction and installation phase is expected to create jobs equaling around 120 person-years. The factory is anticipated to operate at full capacity in 2025.

With the purchase of the latest technology, iSAVER® by Itema, in weaving machines, ISKO pushes the envelope of technological performance and sustainability, making further progress in product and process efficiency.

This decision is an additional, important asset in ISKO’s journey towards a genuine Responsible Innovation™. It is part of other crucial investments made by the company, aimed at further reducing its environmental impact, among which stand out R-TWO™50+ – a new denim generation made with a minimum of 50% pre- and post-consumer recycled blend – and the Green Machine – a pioneering technology providing a 100% post-consumer recycling solution that fully separates and recycles cotton and polyester blends at scale.

After an intensive process, a selection was made where ISKO focuses on the development of technical solutions that enable greater resource savings and more sustainable production methods, always with the protection of workers at heart.

As a result, ISKO’s Headquarters extend the company's long-term relationship with Itema,
strengthening the company’s position as the mill with one of the world’s largest denim capacities. The new rapier machines are enhanced by the iSAVER® technology, a breakthrough mechatronic innovation that eliminates the waste selvedge on the left side of the fabric, allowing for saving in energy and raw materials, cutting in half the cotton waste that typically results from the weft yarn. All types of ISKO’s innovative fabrics, with a multitude of different constructions and fiber mixtures, can now be produced using these advanced weaving technologies, with a special focus given to the R-TWO™ technology in terms of its sustainable credentials.

The EREMA Group, which comprises EREMA Group GmbH and its subsidiaries EREMA, PURE LOOP, UMAC, 3S, KEYCYCLE and PLASMAC, closed the 2021/22 financial year with a 17 percent increase in revenue. Consolidated Group revenue amounted to EUR 295 million, and the number of employees increased to over 840. The EREMA Group remains on course for continued growth.

A closer look at the post consumer segment clearly shows a trend towards larger plants, both for PET recycling and for processing polyolefins. For example, the first VACUREMA® Basic 2628 T machine with an annual capacity of up to 40,000 tonnes was recently commissioned at a customer's site in Brazil. This plant features a ten-meter-long special geometry screw with a diameter of 280 millimetres and a weight of 3.5 tonnes. The screw was developed and manufactured by 3S, a subsidiary of EREMA GmbH.

Demand for previously-owned machines at UMAC also remained high during the past financial year. In addition to the general trend towards plastics recycling, the decisive factor here is that customers are more frequently opting for previously-owned systems available at short notice due to the tense situation on the procurement markets. At the same time, businesses that have so far had little contact with recycling are also becoming increasingly interested in this topic. Their need for feasibility studies, consulting and engineering services, project management and turnkey projects are now also very successfully catered for by KEYCYCLE, an EREMA Group company. KEYCYCLE has also acquired from Cadel Deinking the patent, technology and distribution rights for an innovative ink removal technology, which is now being further developed using the know-how of the EREMA Group and shaped into a product that meets industrial standards.

The initiative launched four years ago to modernise and expand existing EREMA Group sites was continued during the past financial year with the expansion and construction of a dedicated machine demonstration centre for PLASMAC in Milan. Equipped with additional production floor space and new and enlarged customer centres, all companies within the group are now well prepared to meet rising demand, and with the new research and development centre under construction in Ansfelden, the framework for further outstanding plastics recycling milestones from EREMA is currently being optimised.

Cobra International, a leading manufacturer of advanced composite products for the watersports, automotive, marine, and industrial sectors, will highlight recent diversification into new composite markets at JEC World 2022, with exhibits ranging from VTOL drones to carbon fibre prosthetics.  Cobra will also demonstrate how it is working alongside automotive and water sports customers to further enhance the sustainability of products in these sectors.

High Volume Production Capacity for the UAV sector
Cobra will display a wing from the Swiftlet UAV. This compact tactical fixed wing UAV platform has a 5.5m wingspan and was developed by the Royal Thai Air Force and National Science and Technology Development Agency (NSTDA) for survey, monitoring and search and rescue operations. Cobra manufactured the 32kg Swiftlet composite airframe using a combination of CNC cut carbon sandwich internal structure and PVC foam sandwich skins using both high grade glass fibre and carbon fibre reinforcements.  

Sustainability Options for Automotive and Watersports
Sustainability has a been a key focus for the Cobra Waterports division and CAC, the Cobra automotive business unit. At JEC World 2022, Cobra will showcase the increasing material and process options it has developed with both bio-resin and natural fibre reinforcements variants presented alongside more traditional carbon fibre parts.

Visitors will be able to get up close to a new Bio SUP Wingfoil board featuring a basalt, flax, bamboo and GreenPoxy bio-epoxy construction created for partners NSP, as well as state-of-the-art compression moulded prepreg foils. Cobra’s first fully recyclable surfboard incorporating the Recyclamine® resin technology that Cobra was recognised for in the 2020 JEC Innovation Awards will also be on display alongside a new Audi e-tron foil by Aerofoils – the world’s safest electric hydrofoil board.

The CAC team (Automotive Business Unit of Cobra) will present a set of OEM mirror cap parts that showcase a range of carbon SMC, woven visual carbon, pure woven visual flax, hybrid flax-carbon and painted flax construction options for the same component.  Clear carbon aesthetic and structural parts including CAC made M-carbon components for the BMW S 1000 RR Motorcycle will furthermore underline the high quality and eye-for-detail for which CAC is renowned.

Carbon Prosthetics
An entirely new composite application for the company, Cobra will also show two composite prosthetic devices at JEC which were productionised by the in-house design and development team. Working alongside a leading Thai university and a medical device OEM, Cobra created a rapid and cost effective series production process for a lightweight carbon fibre prosthetic foot. In another example of lightweight composites creating major quality of life improvements, Cobra has also designed and manufactured a carbon and glass fibre prepreg foot support for Elysium Industries.

Construction machinery rolls into action again. The ground-breaking ceremony at the EREMA site in Ansfelden on April, 6 signals the start of work on a new R&D centre. Two halls with a total area of 1,550 square metres and a new office building with 50 workplaces will be built. The R&D centre will offer cross-departmental and cross-company test machines and laboratory for research and development of plastics recycling technologies to further advance the circular economy. Completion is scheduled for February 2023.

Plastics recycling is currently evolving very rapidly from a niche to a trend. This is driven by the legislative targets for plastics recycling that the European Union and many countries around the world have enacted, as well as by the European Green Deal, which aims to make Europe the first climate-neutral continent and in which the circular economy plays a very central role.

However, there is not just one recycling solution for all types of plastic waste, but rather different solutions depending on the type of plastic, the product and the application intended for the recycled plastic. While some plastics processing loops, such as for PET bottles, have already been closed, many other plastic waste streams still require a great deal of R&D in cooperation with everyone involved in the value chain to produce recycled pellets that meet the very highest standards for the production of new products. More space will be available for this in the new centre.

R&D is decentralised at EREMA. In recent years, approximately 5 percent of turnover was reinvested annually in research and development. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology, and special technologies with a view to further improving the quality of recycled pellets. They also focus on new recycling technologies for waste plastic materials for which there is currently no satisfactory circular economy solution. The decisive factor here is also to exploit the potential of digitalisation. By collecting and analysing machine data, not only can recycling processes and product quality be further improved, but we can also develop our digital service offering for our customers. Such offerings include customer-specific information tools that feature plant and process data, predictive maintenance and online support as well as commissioning via remote access.

For material tests, which are necessary for research and development work, an expanded machine park will be available following completion of the new R&D centre. Here, the recycling process can be evaluated end-to-end, including upstream and downstream processes such as shredding and further processing of the recycled pellets. The material tests are supported by detailed analysis in the professionally equipped laboratory, which will be relocated to the new premises and upgraded where necessary with the very latest lab equipment.

Up to the age of three, a baby uses around 5,000 diapers. Despite the convenient handling of common disposable diapers, parents are increasingly looking for a healthy and sustainable alternative to these products to avoid waste. In Germany alone, 10 million diapers are disposed of every day.

Ways to solve this dilemma, would be disposable products that are made from bio-based or biodegradable materials, or reusable products with a longer life span replace disposable products.

Founding team Luisa Kahlfeldt and Caspar Böhme combine both with their "Sumo Diapers." These cloth diapers are made entirely of sustainable materials while offering high performance and innovative design.

The Sumo Diaper is a fitted cloth diaper that consists of a waterproof cover and absorbent inserts. The cover is sewn in such a way that a pocket is formed: this is where the absorbent pad is inserted to prevent slipping.

To further enhance the performance of this absorbent pad, the Sumo team partners with the viscose special fibre manufacturer Kelheim Fibres, who brings decades of experience from the hygiene sector, especially for sensitive applications where high absorbency is required (such as tampons). Together, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that uses no fossil materials.

The basis are functionalised specialty viscose fibres with adapted cross-sections. Needle-punched / thermobonded nonwovens with a blend of specialty viscose and PLA bicomponent fibres were chosen to ensure the product's washability. PLA stands for polylactic acid made from natural and renewable raw materials. By combining nonwovens, usually found mainly in the single-use sector, with reusable products, Sumo and Kelheim Fibres have chosen a completely new approach.

Inside the pad, the speciality fibres from Kelheim score with their special properties: In the distribution layer (ADL), the trilobal cross-section of the Galaxy® fibre forms capillary channels that enable efficient and optimized liquid distribution and thus optimum use of the capacity of the absorbent core, offering the lowest rewet values.

In the absorbent core, the segmented hollow fibre Bramante stores liquid not only between but also inside the fibre. The liquid remains there even when pressure is applied to the construction, providing excellent rewet values. Bramante can absorb up to 260% of its own weight in liquid. Cotton only achieves values of around 50% here.

The innovative nonwoven construction with the speciality fibres from Kelheim performs significantly better in tests in terms of air permeability, liquid absorption and rewetting than commercially available solutions made of synthetic fibres or cotton in knitted structures, and has earned Sumo diapers a place among the finalists for the IDEA® Long-Life Product Achievement Award.

The launch is scheduled for the first of May.

Over 600 delegates from 58 countries subscribed to the latest VDMA textile machinery webinar on sustainable dyeing held on February 3rd, 2022 – a record since the monthly online series started in June 2020. The webinar, entitled ‘Resource-saving in Textile Processing – Continuous Dyeing and Washing’, involved the three companies Monforts, DyStar® and Goller.

In outlining the capabilities of Monforts Thermex hotflue lines for the Econtrol® continuous dyeing process, the company’s Textile Technologies Engineer Jonas Beisel observed that the current industry focus is very much on cleaner processes and products in accordance with the Corporate Social Responsibility (CSR) commitments of the major fashion brands, and with further regulations to be expected.

Cellulosics
Econtrol® is a continuous process for the dyeing of woven cellulosic fabrics that has already been well proven on the market, with over 150 Monforts Thermex lines already in operation at mills worldwide.

Reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes at a temperature of between 120-130°C and a relative humidity volume of 25-30%.

Benefits
The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step.

Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

Complementary services and systems
Complementing the Monforts presentation during the webinar, Bertram Seuthe, Global Business Development Manager at DyStar, outlined the importance of specific Levafix® /Remazol® reactive dyes and Dianix® disperse dyes for sustainable dyeing processes such as Econtrol®, Cadira® Continuous and CPB knit. In these processes Sera® auxiliaries are also employed for optimised wash-off results.

Guido Seiler, Area Sales Manager at Fong's Europe, also introduced the latest developments of the Goller brand for the washing process, which can reduce water consumption by between 10 to 20%, as well as reductions in both heating energy and waste generation, depending on the specific fabric construction and required shade.

Strict protective measures will make the industry meeting possible at the International Conference on Cellulose Fibres in Cologne on February 2 and 3, 2022. The latest innovations will be shocased: from hygiene and textiles to non-wovens and carbon fibre alternatives to lightweight construction applications. Online participation is also possible.

Cellulose fibres show an increasingly expanding wide range of applications, while at the same time markets are driven by technological developments and political framework conditions, especially bans and restrictions on plastics and increasing sustainability requirements. The conference provides rich information on opportunities for cellulose fibres through policy assessment, a session on sustainability, recycling and alternative feedstocks as well as latest development in pulp, cellulose fibres and yarns. This includes application such as non-wovens, packaging and composites.

Live at the conference, host nova-Institute and sponsor GIG Karasek GmbH will grand the “Cellulose Fibre Innovation of the Year” award to one of six highly interesting products, ranging from cellulose made of orange and wood pulp to a novel technology for cellulose fibre production. The presentations, election of the winner by the conference audience and the award ceremony will take place on the first day of the conference.

The conference sessions reflect the current topics of industry and research. “Strategies and Market Trends” provides an overview of the rapid development of cellulose fibres and their technological progress across the fibre market. An analysis of the key cost components of these fibres to benchmark against current cost levels will highlight future opportunities and challenges for novel textile fibres. The session will conclude with an overview of the industry's recent strategies to defossilize the fibre market.

The session “New Opportunities for Cellulose Fibres in Replacing Plastics”, focusses on questions such as: “What impact does the ban on plastics in single-use products have on the industry?” and “What are the latest regulatory issues and policy opportunities for cellulose fibres?”. This part of the conference presents new opportunities for the replacement of fossil-based insulating materials with cellulose-based technologies suitable for use in a variety of applications, from aerospace to mobility and construction.
Institutefor Ecology and Innovation

“Sustainability and Circular Economy” highlights crucial issues with regard to the overall goal of keeping the environmental impact of cellulose fibres low. A core theme of the session is the responsible use of wood and forests. With this objective, the five speakers discuss the importance of circular concepts for cellulose feedstocks. Exciting insights into the important “Hot Button Report” are offered by Canopy. The “Hot Button” report enables the producers of cellulose fibres to better understand the impact their raw materials have on forests and the climate development worldwide.
