• Circular economy at Kelheim Fibres: Examples of innovation from raw material, product design and all the way to “end of life”

Kelheim Fibres, the world's first viscose fibre manufacturer with an EMAS-certified environmental management system, is continuously working on optimising its special fibres. These can be functionalised as needed - in many cases to save further processing steps (such as dyeing or coating) and thus energy, water and chemicals - and are completely biodegradable at the end of their product life in a short time (according to OECD Test 301 B).

Currently, the specialists in Kelheim are working on the development of alternative raw materials for the production of viscose fibres, such as recycled cellulose as well as other cellulose-containing starting materials. One approach to closing the product cycle in the textile sector is the use of pulp produced from recycled post-consumer waste materials.

In production, Kelheim Fibres focuses on resource conservation by minimising emissions and waste through closed-loop recovery systems, as well as through highly efficient energy generation and the corresponding operation of the plants.

Dr. Roland Scholz, Project Manager Fibre and Application Development at Kelheim Fibres, will present details of this on Wednesday, 15 September, at 5.50 p.m., in Hall B of the 60th Dornbirn GFC WEBINAR WEEK.

• Long-term partnership between the Austrian textile producer FEINJERSEY and the German textile machinery manufacturer BRÜCKNER

The Feinjersey Group is an internationally operating textile company and supplies the "global players" of the textile industry worldwide. The value chain of the company, which is based in Götzis, Austria, ranges from yarn processing to the finished product.

As a fully integrated production company, the internationally active textile company Feinjersey attaches great importance to a high quality standard and guarantees care at every step in the process chain. With approx. 250 employees and annual sales of around 45 million euros, the company knits, dyes and finishes top-quality knitted fabrics as well as elastic woven fabrics for a wide range of applications.

Products are made for the fashion, sports, workwear and technical textiles sectors. Among other things, fabrics for the automotive industry, laminating backings and coating substrate for artificial leather or foils, construction textiles or fabrics for medical technology are all produced.

The Austrian textile manufacturer has been certified with the Bluesign textile seal and ensures efficient use of resources with modern machinery. Water and energy consumption as well as pollutant emissions are to be reduced to a minimum.

In textile finishing in particular, the focus is on minimising energy consumption as this process is the most energy-intensive in the entire process chain. Feinjersey uses its own photovoltaic system for this purpose, as well as the heat recovery and exhaust air purification systems on the stenter frames. By using the waste heat from production, the company's buildings are heated. All six stenter frames at Feinjersey are made by BRÜCKNER and produce with three-stage heat recovery and exhaust air purification systems.

The latest BRÜCKNER line has a working width of 4.20 m and is mainly used for the finishing of high-ly elastic and extremely sensitive knitted fabric. In order to avoid yellowing on the fabric, the stenter is equipped with an indirect gas heating system. The knitting oil vapours coming from the fabric during the heat-setting process are extracted from the dryer and cleaned in a BRÜCK-NER ECO-AIR exhaust air cleaning system before being extracted to atmosphere. The complete exhaust air treat-ment on the newest stenter is carried out by a multistage BRÜCKNER ECO-HEAT and ECO-AIR system.

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.

Composites Evolution Ltd has teamed up with leading natural fibre reinforcement specialists Bcomp to launch a new range of flax-epoxy prepreg materials, designed to offer enhanced sustainability without compromising on performance.

Evopreg ampliTex™ prepregs combine Composites Evolution’s high-performance Evopreg epoxy resin systems with Bcomp’s award-winning ampliTex™ flax reinforcements, to deliver a family of materials which offer outstanding performance for component applications.

To reach the full performance of natural fibres, Evopreg ampliTex™ prepregs have been tailored to be compatible with Bcomp’s powerRibs™ reinforcement grid, enabling the same stiffness and weight as thin-walled monolithic carbon fibre parts while decreasing the CO₂ footprint by 85% and improving safety thanks to a blunt braking behaviour without dangerous debris or sharp edges.

Composites Evolution’s Sales & Marketing Director, Ben Hargreaves, explains further.
“Sustainability is an increasingly important factor for many of our customers - particularly those involved in motorsports and high-performance automotive applications. As you’d expect in these sectors though, sustainability can’t come at the expense of performance the two must go hand-in-hand. This is something that other prepreggers can struggle with, as natural fibres behave very differently to carbon or glass, for example.”

Customers would be able to understand the strengths and weaknesses of natural fibre composites, and to show where and how they can be adopted without the need for significant changes to existing composite component production processes.

One such customer is Retrac Group, whose composites division is one of the UK’s most experienced composites engineering companies across motorsports, automotive and aerospace. It recently used Evopreg ampliTex™ + powerRibs™ to produce a demonstrator bonnet panel for a race-bred supercar. Project Manager Alan Purves explains.

“We’re seeing a growing interest in flax fibre composites, particularly in the motorsports and niche vehicle sectors. It is therefore essential that we have developed an in-depth understanding of the processing requirements and performance capabilities of these materials, and are ready to respond to our customers' requirements. Being able to tap into the combined expertise and experience of both Composites Evolution and Bcomp is proving invaluable.”

• 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.

100% sustainability lives in the smallest detail, starting with the label, the element that can tell the story of responsibility. This is why Nastrificio di Cassano has created NDC Green, Made in Italy and fully traceable range that guarantees high quality standards while respecting the planet.
 
NDC Green comprises 4 categories:

• LABìO ECO-SOFT®: made using TENCEL™ lyocell  yarn which is compostable and biodegradable (as attested by TUV Austria), this product boasts performances and is resistant up to 10 domestic washings at 30°. The reference is produced with fifteen times less water consumption than cotton production and the resins used are GOTS certified.
• LABìO HANGreen is the smart solution for the creation of hard tags, hangtags, shopping bags and garment covers and, as LABIO ECO-SOFT® range, it’s made with  compostable and biodegradable TENCEL™ lyocell yarn and the resin is compostable, too. These peculiarities make this product unique.

This production will be independently verified by Textile Exchange audit bodies.

This achievement is made possible using ISKO’s R-TWO™ technology which is created through a patented and exclusive yarn spinning technique that retains the unique properties and benefits found in ISKO’s statement fabrics. ISKO’s R-TWO™ is the embodiment of its Responsible Innovation™ mindset and aligns with the principles of a circular economy espoused by the Ellen MacArthur Foundation – to ensure durability, material health, recyclability and traceability. R-TWO™ positions ISKO as a sustainability leader and enables it to exceed the project guidelines to create denim that is designed to be used more, made to be made again and made from safe and recycled or renewable inputs.

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.

100% sustainability lives in the smallest detail, starting with the label, the only element that can tell the story of responsibility. This is exactly why, to be a truly credible 'ambassador', the label or tag must itself be responsible. This is why Nastrificio di Cassano has created NDC Green, the premium, Made in Italy and fully traceable range that guarantees the highest quality standards while respecting the planet.

NDC Green comprises 4 categories, all with influential international certifications that attest to Nastrificio di Cassano's responsible imprinting. Many new sustainability values are woven into the collection. Particular attention is given to end-of-life, but also to the choice of natural and high-tech materials with a low environmental impact.

A wide choice that speaks of responsible innovation, beauty and functionality: characteristics that have led C.L.A.S.S. (www.classecohub.org) to integrate NDC Green into its Material Hub which "contains a selection of fibres, materials and fabrics that share a DNA linked to research that since 2007 has been raising the bar of standards in order to offer innovations in step with the demands of the contemporary consumer" says Giusy Bettoni CEO of C.L.A.S.S.
NDC Green includes:

• LABìO ECO-SOFT®: made using compostable and biodegradable ingredients (as attested by TUV Austria), this product boasts performances and is resistant up to 10 domestic washings at 30°.
