From the Sector

The “Cellulose Fibres Conference 2024” held in Cologne on 13-14 March demonstrated the innovative power of the cellulose fibre industry. Several projects and scale-ups for textiles, hygiene products, construction and packaging showed the growth and bright future of this industry, supported by the policy framework to reduce single-use plastic products, such as the Single Use Plastics Directive (SUPD) in Europe.

40 international speakers presented the latest market trends in their industry and illustrated the innovation potential of cellulose fibres. Leading experts introduced new technologies for the recycling of cellulose-rich raw materials and gave insights into circular economy practices in the fields of textiles, hygiene, construction and packaging. All presentations were followed by exciting panel discussions with active audience participation including numerous questions and comments from the audience in Cologne and online. Once again, the Cellulose Fibres Conference proved to be an excellent networking opportunity to the 214 participants and 23 exhibitors from 27 countries. The annual conference is a unique meeting point for the global cellulose fibre industry.  

For the fourth time, nova-Institute has awarded the “Cellulose Fibre Innovation of the Year” Award at the Cellulose Fibres Conference. The Innovation Award recognises applications and innovations that will lead the way in the industry’s transition to sustainable fibres. Close race between the nominees – “The Straw Flexi-Dress” by DITF & VRETENA (Germany), cellulose textile fibre from unbleached straw pulp, is the winning cellulose fibre innovation 2024, followed by HONEXT (Spain) with the “HONEXT® Board FR-B (B-s1, d0)” from fibre waste from the paper industry, while TreeToTextile (Sweden) with their “New Generation of Bio-based and Resource-efficient Fibre” won third place.

Prior to the event, the conference advisory board had nominated six remarkable innovations for the award. The nominees were neck and neck, when the winners were elected in a live vote by the audience on the first day of the conference.

First place
DITF & VRETENA (Germany): The Straw Flexi-Dress – Design Meets Sustainability
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

Second place
Honext Material (Spain): HONEXT® Board FR-B (B-s1, d0) – Flame-retardant Board made From Upcycled Fibre Waste From the Paper Industry
HONEXT® FR-B board (B-s1, d0) is a flame-retardant board made from 100 % upcycled industrial waste fibres from the paper industry. Thanks to innovations in biotechnology, paper sludge is upcycled – the previously “worthless” residue from paper making – to create a fully recyclable material, all without the use of resins. This lightweight and easy-to-handle board boasts high mechanical performance and stability, along with low thermal conductivity, making it perfect for various applications in all interior environments where fire safety is a priority. The material is non-toxic, with no added VOCs, ensuring safety for both people and the planet. A sustainable and healthy material for the built environment, it achieves Cradle-to-Cradle Certified GOLD, and Material Health CertificateTM Gold Level version 4.0 with a carbon-negative footprint. Additionally, the product is verified in the Product Environmental Footprint.

Third Place
TreeToTextile (Sweden): A New Generation of Bio-based and Resource-efficient Fibre
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn’t exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.

The next conference will be held on 12-13 March 2025.

Dibella will present its circular bed linen “Versailles” at the Sustainable Design Summit and the Cruise Ship Interiors Design Expo in London. Dibella is thus once again underpinning its reputation as a pioneer in the field of sustainability.

The Bocholt-based company is presenting its new innovation for the first time at the Sustainable Design Summit on 28 November 2023 at the Museum of London Docklands. International visitors from the cruise, hotel and aviation sectors will have the opportunity to find out more about the first circular bed linen "Versailles".

At the subsequent Cruise Ship Interiors Design Expo from 29 to 30 November 2023 at ExCeL in London, Dibella will be exhibiting for the second time after a successful start in 2022. Under the motto "Almost too good to get out of bed", Dibella will be presenting its new innovation "Versailles", its multi-certified products, the company and its customised services and benefits.

With "Versailles", Dibella is realising its vision of a closed-loop economy. The specialist for sustainable contract textiles has succeeded in recycling old, no longer usable bed linen into new fibres and weaving them into new bed linen.

Avantium N.V., a leading technology provider in renewable chemistry, announces that it has signed an offtake agreement with Kvadrat A/S, a leader in design innovation, producing quality contemporary textiles and textile related products for architects, designers, and private consumers across the world.

Kvadrat will purchase the 100% plant-based and fully recyclable polymer PEF (polyethylene furanoate) from Avantium’s FDCA (furandicarboxylic acid) Flagship Plant, currently under construction in Delfzijl (the Netherlands) and with commercial production set to start in 2024.

The offtake agreement shall offer Kvadrat the advantage of being first mover in creating PEF-based textiles for both commercial and residential interiors.

At Heimtextil Frankfurt 2022, Devan, will launch novel technologies to the Home Textiles market. The first innovation is a range of bio-based and biodegradable microcapsules. With increased sustainability and circularity requirements in Europe and beyond, Devan is pushing the limits further of its encapsulation methods, also in terms of wash durability. The capsules are biodegradable and hence no harm for risk of microplastics. The new R-Vital NTL range includes evergreen Aloe Vera, waste-material based avocado seed oil with very high hydration abilities! and Vitamine E.

Devan, as part of the Pulcra Chemicals Group, co-launches the new Pulcra TEC-SU, a new biobased C0 DWR. This hydrophobic agent has a bio-content above 60% and contains no APEO or formaldehyde. It keeps performing very good after multiple washings.

The Devan bio-based thermoregulation range, like Tones of Cool Bio which is already several years on the market, is having a positive effect on carbon footprint. Devan is now expanding its cooling range with a specific foam-solution. In the Home Textile industry new (bio)foam types are introduced the last 1,5 years to comply with the EU GreenDeal and circularity / recycling requirements. A good enough reason for Devan to develop a foam-specific cooling system. After all, research shows that our bedroom interiors get warmer every year, partly due to better insulation but also due to global warming. On top of that Devan thermoregulation solutions can save Energy and Water during application: low curing solutions are available next to cooling products to that can be applied, using less water.

The acoustic performance of components for the vehicle interior such as inner dashes or carpets depends on the noise-reducing quality as well as the geometrical adaptability and fill power of their material. With Flexi-Loft, Autoneum offers a new felt-based technology that thanks to a unique blend of recycled cotton and functional fibers reduces product weight and allows for accurate adaptation even to complex shapes. The textile material therefore provides a versatile and more sustainable alternative to foam.

In order to achieve high acoustic performance at minimum weight and maximum sustainability, Autoneum is continuously advancing its textile product portfolio. When it comes to components for the vehicle interior, for example, standard thermoplastic felts excel through their acoustic absorption, robustness and environmental friendliness. However, since felt-based materials are generally less voluminous and moldable as foam components, they require more weight to thoroughly fill the areas of varying thickness between the surface of the component and the vehicle’s body-in-white. In contrast, Autoneum’s Flexi-Loft technology is significantly lighter, more flexible and more adaptable than standard felts. In addition, the fiber-based material is versatile and clearly outperforms current foam products in terms of sustainability.

Thanks to its blend of recycled cotton and polyester fibers, Flexi-Loft substantially reduces component weight while improving geometrical adaptability and acoustic performance, especially in areas of low thickness. Thanks to the specific properties of the fibers, Flexi-Loft enables a precise adaptation to a wide variety of vehicle bodies, thereby improving the noise-insulating qualities of the respective product. Even at low weight, Flexi-Loft covers a wide range of material thicknesses, thus proving to be an ideal decoupling material for interior components with complex shapes such as inner dashes and automotive carpets. As a lightweight, flexible and sustainable alternative to both standard felts and foam, Flexi-Loft distinguishes itself by its versatile application in combination with existing Autoneum technologies such as Hybrid-Acoustics and Prime-Light. Moreover, the material helps to reduce odor and dust inside the vehicle.

Flexi-Loft consists of at least 50% recycled cotton fibers, and cut-offs generated during the manufacturing process are reclaimed, processed and then reused in the production of new felt blanks.

Autoneum is already using Flexi-Loft worldwide as an insulator for various carpets, inner dashes and other acoustic components based on its Prime-Light technology. The application of the material as an effective decoupler in inner dashes made of Hybrid-Acoustics will be launched on the European market in 2023.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

As your development partner, vombaur facilitates innovative composites projects for challenging applications. In innovative and safety-sensitive industries such as automotive and aviation, chemical and plant engineering.  The composites experts at vombaur develop, create samples of and manufacture woven tapes and seamless round or shaped woven textiles by vombaur – in collaboration with the customer's enterprise development teams and individually for the respective projects. This is how novel and unique lightweight components made of high-performance textiles are created for visionary lightweight construction projects.

"Fibre-reinforced composites are the ideal material for future-oriented construction projects," explains Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "Their outstanding technical properties and design possibilities open up new and fascinating perspectives for construction projects. From building construction to civil engineering, from bridge construction to interior design. As an experienced development partner for sophisticated lightweight components, we at vombaur contribute our seamless solutions to these kinds of future-oriented projects."

• Testing and development achieve rigidity and safety milestone

Basaltex, pioneers in innovative uses of basalt fibres, has achieved a significant milestone in developing and testing a new composite material solution comprising fibres of basalt combined with EconCore’s patented honeycomb technology.

This new material development has greatly improved fire resistance and is highly rigid, as well as the usual honeycomb properties of light-weighting.

The company has tested the composite of basalt fibres, a bio resin and rPET honeycomb.

Filaments of only stone fibres are extruded at a temperature of 1450°C, similar to glass but with a number of advantages, not least the absence of boric acid in the process.

Combining this ecological fibre with EconCore’s sustainable technology using rPET, and the bioresin polyfurfuryl alcohol - 100% derived from a waste stream of sugar cane - make this a very sustainable and environmentally friendly product, unlike the majority of thermoset solutions in this type of application.

Railway applications require materials with enhanced fire resistance and the testing has shown that the EconCore-Basaltex solution fits these needs well, at the same time offering the perspective of drastic weight reduction against traditional monolithic GRPs used rather widely in train interiors.

Such sandwich panel could be deployed in applications such as cladding panels, partitions, tables and flooring. The thermoset skin layers give a fast cure at elevated temperature, meaning short cycle time and enabling automated production’.

As well as the railway interior application, this new material combination could be used in any application that requires fire performance combined with a low weight.

Progressive material innovations presented digitally: following the cancellation of this year’s fair due to the corona pandemic, Heimtextil is extending its range of digital services and launching a new online materials library entitled ‘Future Materials Library’. 24 future-oriented materials for interior applications can now be found at www.heimtextil.messefrankfurt.com/future.

The curators of the new materials library are London-based futures-research agency, FranklinTill. “We are transitioning to a materials revolution that will help restore the balance in our relationship to our planet. As part of the Heimtextil Trends 21/22, we present a new selection of materials for interior applications with exciting innovations from all over the world”, says Caroline Till of FranklinTill.

A mix of commercially viable products and developments in an early stage

Imaginative designers and environmentally-aware manufacturers: the Future Materials Library 2021 offers materials pioneers a platform and presents a first-class mix of economically proven and revolutionary developments. FranklinTill has organised the materials in four themes: REGENERATIVE CROPS, REMADE FIBRES, HARVESTING WASTE STREAMS and SUSTAINABLE COLOUR.

Resources are running low

Thus, the new Heimtextil materials library tackles one of the main problems of the modern age: the shortage of resources on earth. In particular, textile production creates huge and continuously growing quantities of waste. And, over past decades, the design business has developed a ‘take, make and discard’ model of consumption that is incredibly harmful for our planet. In the climate-emergency era, however, future-oriented designers are learning from nature and working together with it. They endeavour to make use of the power of highly efficient natural circular systems to create textiles and materials that are better for both humans and the planet.

Heimtextil Trends: a guide for the international sector

The ‘Future Materials Library’ is part of the Heimtextil Trends that, for almost three decades, have been offering orientation for the sector by revealing design tendencies for the coming season. Even in the crisis, the Heimtextil Trends remain a vital part of the overall concept of the fair and provide important content for all target groups involved within the worldwide sector. Accordingly, Heimtextil aims to spotlight style-defining design developments taking place within the larger context of lifestyle trends. At the same time, the Heimtextil trend experts scan the exhibitors’ product world and identify unequivocal trends in the sector. In this connection, particular attention is paid to sustainable aspects along the entire value chain – in both the new digital library and live during the fair next January. 

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.
