From the Sector

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

Iluna Group comes back to Milano Unica with a great and important goal: to relaunch the qualities and dimensions of sustainability by going beyond the ingredient.

Iluna’s new path, which was born in a moment when the market seems to speak about “fragility”, begins with the investment in the renewal of machines, which allow it to fly ever higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. Including cord yarn, shiny threads and an expansion of the range of GRS yarns, previously available only opaque. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.

The printing processes are also born from this constant search for innovation towards new materials and new techniques, becoming more and more sustainable: Global Recycle Standard (GRS)-certified sublimation printing and register printing carrying Global Organic Textile Standard (GOTS) certification. This one overlap exactly on the design and color the details, reaching where the dye cannot reach.

Diversification has become essential in today’s competitive market and the fragility of the moments experienced in 2020 was the stimulus to return to being here again, to return to action. Flexibility is the watchword today, along with research. And Iluna has managed to go further: starting from the ingredients at the base of the materials, last year launched a collection with natural dyes made with GOTS certified plant-based dyes, up to proposing magnificent prints with extraordinary effects for this edition of the Milanese fair.

The three dimensions of sustainability, design and innovation are thus finally linked thanks to valuable partnerships with expert and excellent reference companies that have allowed these new developments and these unique results thanks to advanced technologies designed specifically for Iluna, which is today the only company to offer ingredients, natural colors and prints, all three strictly certified.

• Organic cotton project with thriving prospects

Dibella is participating in a joint project to promote organic cotton cultivation in India. The project aims to protect organic cultivation through targeted training measures and by paying premiums to small farmers, to support the conversion from conventional to organic cotton, to increase crop yields and at the same time to achieve better fibre quality.

The demand for organically grown organic cotton is growing rapidly, but crop yields are lagging well behind global demand. The Alliance for Sustainable Textiles (Berlin), initiated by Development Minister Dr. Gerd Müller, therefore wants to increase organic cotton volumes for its member companies with practical solutions. In cooperation with the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), it is now promoting a forward-looking project for which Dibella provided the impetus.

"In India, it is mainly micro-farms and village cooperatives that are active in organic cotton cultivation. Conversion of additional land and sustainable management could increase yields and fibre quality of organic cotton. The Chetna Organic initiative, with which we have been working successfully for many years, advises the farmers in these processes. It supports the farmers and village communities with targeted education, training and practical assistance in organic farming, thus preparing the ground for better income and living conditions for the families," says Ralf Hellmann, Managing Director of Dibella.

Several alliance partners - Dibella, Fairtrade Germany, GIZ, Organic Cotton Accelerator (OCA) and Tchibo - have taken the exemplary initiative as an opportunity to promote the cultivation and expansion of organic cotton in India. In cooperation with Chetna Organic, they focus on supporting Indian women's cooperatives, women farmers and families in the production of organic cotton as part of the "Organic Cotton Pilot Project". Tchibo and Fairtrade subsidise micro-farms during the conversion phase of the fields (the fibres are only recognised as organic cotton four years after conversion) and contribute to the provision of GMO-free seeds, which have become a scarce commodity in India. Together with Dibella, they finance training courses that teach the optimal use of natural rainfall as well as efficient, ecological cultivation methods, which subsequently lead to improved fibre quality. In addition, they commit to purchasing Fairtrade organic cotton for many years.

Ralf Hellmann: "The pilot project enables us to expand our Dibella Good Textiles collection because it guarantees us long-term access to fair-trade organic cotton. At the same time, it improves the living conditions of the small-scale farmers and their families. We therefore hope that "Organic Cotton" will also set a precedent in other cotton growing regions and bring organic farming forward in India."

International technology Group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at ANEX/SINCE 2021 in Shanghai, China, from July 22 to 24, 2021. The product portfolio covers state-of-the-art nonwovens and textile production technologies such as air-through bonding, needlepunch, spunlace, spunbond, wetlaid/Wetlace, converting, textile finishing, airlay, recycling, and bast fiber processing.

Among the largest end-use markets for nonwoven products are materials for durable uses. Interior linings for cars, materials for construction, geotextiles, synthetic leathers for clothing and furniture, carpeting, filtration and many other industries rely on the use of nonwovens produced using the needlepunch method.

ANDRITZ Nonwoven’s processes play a pioneering role in the production of biodegradable materials. For many years, ANDRITZ has offered different processes, like spunlace, Wetlace and Wetlace CP, all with one goal in mind: Elimination of plastic components while maintaining the high quality of the desired product properties. Such processes achieve high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo or linen, without chemical additives results in a 100% sustainable fabric, thus meeting customers’ needs exactly as well as supporting the strong tendency to move away from plastics and synthetics.

The latest development in this field is the ANDRITZ neXline wetlace CP line. This process combines the benefits of two forming technologies (inline drylaid and wetlaid web forming process) with bonding by hydroentanglement. Natural fibers, like pulp or viscose, can be processed smoothly and generate a high-performance and cost-efficient wipe that is fully biodegradable and plastic-free.

• Fraunhofer, SABIC, and Procter & Gamble join forces
• The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE and its Institute for Environmental, Safety and Energy Technology UMSICHT have developed an advanced recycling process for used plastics.
• The pilot project with SABIC and Procter & Gamble serves to demonstrate the feasibility of closed-loop recycling for single-use facemasks.

Due to COVID-19, use of billions of disposable facemasks is raising environmental concerns especially when they are thoughtlessly discarded in public spaces, including - parks, open-air venues and beaches. Apart from the challenge of dealing with such huge volumes of essential personal healthcare items in a sustainable way, simply throwing the used masks away for disposal on landfill sites or in incineration plants represents a loss of valuable feedstock for new material.

“Recognizing the challenge, we set out to explore how used facemasks could potentially be returned into the value chain of new facemask production”, says Dr. Peter Dziezok, Director R&D Open Innovation at P&G. “But creating a true circular solution from both a sustainable and an economically feasible perspective takes partners. Therefore, we teamed up with Fraunhofer CCPE and Fraunhofer UMSICHT’s expert scientists and SABIC’s Technology & Innovation specialists to investigate potential solutions.”

As part of the pilot, P&G collected used facemasks worn by employees or given to visitors at its manufacturing and research sites in Germany. Although those masks are always disposed of responsibly, there was no ideal route in place to recycle them efficiently. To help demonstrate a potential step change in this scenario, special collection bins were set up, and the collected used masks were sent to Fraunhofer for further processing in a dedicated research pyrolysis plant.

“A single-use medical product such as a face mask has high hygiene requirements, both in terms of disposal and production. Mechanical recycling, would have not done the job”, explains Dr. Alexander Hofmann, Head of Department Recycling Management at Fraunhofer UMSICHT. “In our solution, therefore, the masks were first automatically shredded and then thermochemically converted to pyrolysis oil. Pyrolysis breaks the plastic down into molecular fragments under pressure and heat, which will also destroy any residual pollutants or pathogens, such as the Coronavirus. In this way it is possible to produce feedstock for new plastics in virgin quality that can also meet the requirements for medical products”, adds Hofmann, who is also Head of Research Department “Advanced Recycling” at Fraunhofer CCPE.

The pyrolysis oil was then sent to SABIC to be used as feedstock for the production of new PP resin. The resins were produced using the widely recognized principle of mass balance to combine the alternative feedstock with fossil-based feedstock in the production process. Mass balance is considered a crucial bridge between today’s large scale linear economy and the more sustainable circular economy of the future, which today is operated on a smaller scale but is expected to grow quickly.

“The high-quality circular PP polymer obtained in this pilot clearly demonstrates that closed-loop recycling is achievable through active collaboration of players from across the value chain”, emphasizes Mark Vester, Global Circular Economy Leader at SABIC. “The circular material is part of our TRUCIRCLE™ portfolio, aimed at preventing valuable used plastic from becoming waste and at mitigating the depletion of fossil resources.”

Finally, to close the loop, the PP polymer was supplied to P&G, where it was processed into non-woven fibers material. “This pilot project has helped us to assess if the close loop approach could work for hygienic and medical grade plastics”, says Hansjörg Reick, P&G Senior Director Open Innovation. “Of course, further work is needed but the results so far have been very encouraging.”

The entire closed loop pilot project from facemask collection to production was developed and implemented within seven months. The transferability of advanced recycling to other feedstocks and chemical products is being further researched at Fraunhofer CCPE.

We aRe Spin Dye (WRSD) AB (publ) (“WRSD”) enters into a collaboration agreement with the international premium brand, Hugo Boss.

Hugo Boss has a clear agenda for how they will gradually become even more sustainable. One of the company's intermediate goals is to have reduced total water consumption by 40% by 2025 - where WRSD is expected to be involved and contribute with competence and technology. The long term goal for Hugo Boss is to be completely climate neutral by 2050.

In November, Hugo Boss Ag entered the Dow Jones Sustainability Index (DJSI) World for the fourth year in a row. Hugo Boss is thus one of the four companies in the textile, clothing and luxury segment that have qualified for the index this year. Hugo Boss is also listed in the Dow Jones Sustainability Index (DJSI) Europe for the first time. In the assessment carried out by S&P Global, HUGO BOSS improved significantly compared with the previous year and received, among other things, the assessment “best in class” in several categories.

International technology Group ANDRITZ has always been at the forefront in providing innovative and sustainable solutions for the global nonwovens industry. Optimization of resource management, especially reducing the consumption of raw materials and other substances used and also keeping resources in use for as long as possible, are decisive factors in enabling nonwovens producers to offer competitive and sustainable products.

As a world market leader for nonwovens production equipment and services, ANDRITZ offers a full range of products to meet these challenging demands.

Maximizing the evenness of the product across the entire production line is one of the key success factors. The weight profiling product range of ANDRITZ – consisting of ProDynTM and ProWidTM – has been extended by ProWinTM. This new development is the combination of the two existing systems ProDynTM and ProWidTM. It allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15% at the same time. ProWin combines the long-term process experience and in-depth knowledge ANDRITZ has on needlepunch lines with innovative software to synchronize action across the line. Guillaume Julien, Head of Needlepunch Sales at ANDRITZ Nonwoven, explains,

“We have developed a self-regulating, advanced technology to reduce fiber deposits at the edges of the web and eliminate the “smile” effect across its width. ProWin enables producers to optimize the CV ratio autonomously and precisely while also generating significant fiber savings of up to 10% and increasing production speed. Thus, it also provides a faster ROI.“

When it comes to the spunlace process, a better product quality can be obtained by ensuring that the different equipment units in the production line are consistent with one another. The TT card, the Jetlace hydroentanglement unit, and the neXdry through-air dryer are the perfect combination to obtain premium visual quality and characteristics in the web. For an equivalent amount of fibers, this set-up is designed to produce an even web with significant bulkiness and an excellent MD:CD ratio without impacting the production capacity.

Maximizing performance by minimizing the raw material input and the amount of waste produced is a real driver of cost optimization. This is why ANDRITZ has created and integrated a solution that allows nonwovens producers to retrieve the wasted edges of their spunlace fabric and re-use it as recycled fibers. As a result, roll-good producers can even obtain the same web characteristics as when using virgin fibers, and most importantly, the exact same quality.

ANDRITZ also offers – under the brand Metris – ANDRITZ digital solutions – a variety of several service apps for optimum customer benefit. The Metris Cost Management app is used to track raw material consumption. It is an advanced system aimed at monitoring fiber consumption and allowing in-depth diagnoses to investigate raw material losses and savings grouped by different process areas. Thanks to this Metris application, ANDRITZ customers are able to optimize their system’s consumption of raw materials.

All these innovations are available in ANDRITZ’s technical centers, where ANDRITZ process experts will be glad to welcome customers in order to discuss and define their product expectations.

Sappi is expanding its product range for corrugated board applications with Fusion Nature Plus.

With Fusion Nature Plus, Sappi is launching an uncoated, fully bleached and completely recyclable virgin fibre liner. The company provides a unique variety of packaging and speciality papers. The specialist in paper-based solutions also offers a wide range of products in relation to labels. Fusion Nature Plus offers excellent printing results in flexographic, digital and offset printing processes.

• Ultra-bright, uncoated virgin fibre paper with excellent printing results
• Ideal for attractive corrugated board as well as premium shopping bags
• Can be used as topliner, liner or fluting
• Available in grammages of 80 to 130 g/m²

The virgin fibre liner is based on the concept of the successful Fusion Topliner. In contrast to the double-coated Fusion Topliner, Fusion Nature Plus has a natural, uncoated surface with a more tactile feel, in response to the growing market appetite for this type of product. The liner is also provided in very low grammages.

Fusion Nature Plus enhances brand appearance

Brand owners, corrugated board processors, manufacturers of display cartons and folding cartons as well as designers all benefit from the versatility of the new Fusion Nature Plus. In contrast to conventional uncoated liner papers, the material offers high brightness, brilliant colour reproduction and consistently high quality. These features make the product the perfect choice for corrugated board or solid board packaging, where a very bright appearance is needed for topliners, inner liners and corrugating applications. Whether used as an inlay in cosmetics or confectionery packaging, or as a liner in shipping packaging to ensure an exceptional unboxing experience, Fusion Nature Plus is called upon wherever an enhanced appearance is desired.

Another area of application is paper carrier bags, where uncoated paper qualities are often preferred.

Fusion Nature Plus is ideally suited to a range of printing processes: the product achieves outstanding results in flexographic and offset printing. The pre-treated surface and high brightness offer clear advantages with regard to primer requirements and print behaviour, especially for inkjet-based digital printing. Bernd Gelder, Head of Sales Containerboard at Sappi Europe: ‘With its exceptional print quality and impressive colour reproduction, Fusion Nature Plus particularly appeals to packaging customers who value a natural look and feel in paper. The response from the market, in which packaging based on corrugated board still needs to take on a bigger role, is enormous, of course, with the result that we have succeeded in completing a number of interesting end applications and customer projects with Fusion Nature Plus shortly after market launch.’

Virgin fibre vital for recycling

In continuous recycling use, fiber that has already been recycled is subject to a progressive weakening of quality, resulting in a weakness in the products that incorporate them, but also, crucially, over time they will ultimately degrade to a point where they become unrecoverable. As a result, a certain amount of virgin fibre needs to be introduced into the cycle on a regular basis. Without continuous virgin fibre contribution to the pulp cycle, recycled producers will in the end run out of raw material. The premium virgin fibre liner Fusion Nature Plus from Sappi plays an important role here in maintaining the quality of the recycling substrate.

Thanks to the central location of Sappi’s production site in Ehingen, Fusion Nature Plus can be supplied quickly throughout Europe. The shorter transportation distances reduce transport related fossil emissions and protect the environment. The shorter production cycles in turn ensure high availability and rapid supply.

Fusion Nature Plus is currently available in six grammages from 80 to 130 g/m² in both sheet and roll form. Sappi can also provide Fusion Nature Plus with FSC or PEFC certificates on request.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.
