• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer 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 projects.

Elleti Group, an Italian manufacturer specialized in denim treatments and garment making, will present an innovative approach: how we experience denim and its transformation processes.

Elleti Group will display its “Green Replicants” project in a new and improved “Lighter. Better. Wiser.” edition.  This project, inaugurated a few years ago, recreates some of the iconic pieces from the Elleti Group Museum of Denim (dating back to the 19th century) with today’s most advanced environmentally sustainable technologies. This special edition replicas are fully developed using the latest addition to the sustainable tools of the company: the “Wiser Wash” technology, a patented washing method that eliminates the use of all potentially harmful chemicals and pumice stone, while drastically reducing the water consumption throughout the process.
 
Moreover, at the Immaterial M.O.D.E. booth, a special project designed by Denim Première Vision and realized in collaboration with Elleti Group and Sense – Immaterial Reality will take visitors through an Augmented Reality installation to explore a selection of legendary pieces from M.O.D.E., Museum of Denim by Elleti Group. By downloading the app, available on every digital store, on your phone or tablet and looking out for the signage on site, unique denim masterpieces will be at everyone’s fingertips.

Itema, a worldwide manufacturer of weaving solutions, will be for the first time at the Denim Première Vision fair. The company is renowned in the industry to be one of the only manufacturers to produce all the top three weft insertion technologies – rapier, air-jet and projectile.

The company will highlight the iSAVER® technology: designed by Itemalab®, the Itema advanced innovation company. Thanks to iSAVER®, one thousand kilos of cotton per loom a year will be saved – i.e. 3% of total raw materials – which will prevent wasting 20 million litres of water, while saving costs for about €2.000 a year on each loom. iSAVER® significantly contributes in making the denim production greener.

Recycling is the key factor in achieving the EU climate targets. This is shown by the results of the "resources SAVED by recycling" study published today, which Fraunhofer UMSICHT prepared on behalf of the ALBA Group, one of the ten leading recycling companies worldwide. According to the study, 3.5 million tons of greenhouse gas emissions and 28.8 million tons of primary resources could be saved in 2020 alone. Further potential could be raised, for example, through minimum quotas for the use of recycled raw materials.

“Fit for 55” thanks to the circular economy: the recycling of raw materials leads to a systematic reduction in the greenhouse gas emissions of our civilisation – and can therefore make a key contribution to achieving the EU climate goals. This is the outcome of the “resources SAVED by recycling” study presented today, which the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT prepared on behalf of the ALBA Group. Thanks to the closed-loop circulation of 4.8 million tonnes of recyclable materials, the ALBA Group succeeded in preventing some 3.5 million tonnes of climate-damaging greenhouse gas emissions in the year 2020 alone. This amount is equivalent to the emissions from some five million return flights between Frankfurt am Main and Mallorca. At the same time, recycling also secures valuable raw materials for the industry: in 2020, in comparison with primary production, recycling saved 28.8 million tonnes of resources, such as crude oil and iron ore.

“The circular economy is one of the strongest pace-setters on the journey to achieving climate neutrality,” highlights Dr. Axel Schweitzer, CEO of the ALBA Group. “We will only achieve the goal of reducing greenhouse gas emissions by at least 55 per cent throughout Europe by 2030 if we make consistent use of recycled raw materials.” This includes the area of plastics, for example: compared with primary plastics made from crude oil, the use of high-quality recycled plastics achieves a reduction of greenhouse gas emissions of more than 50 per cent. “It is now necessary to lever this potential,” explains Schweitzer. “We are expecting the new Federal Government in Germany to act decisively and push ahead directly with the transition to a circular economy. The environmental benefits of recycling due to its clearly superior CO2 balance should also find reflection in prices. As immediate climate protection measures, clear industry standards for recyclates combined with minimum quotas on the use of recycled raw materials in products and packaging are also urgently necessary. Last but not least, the state sector is also called upon to prioritise resource protection in the area of procurement. Sustainable procurement can ultimately provide a significant boost to the circular economy”.

Plastics, metals, waste electrical (and electronic) equipment, wood, paper, cardboard, cartons or glass: the Fraunhofer UMSICHT has now been researching the specific benefits of recycling for 14 years. Detailed comparisons have also been made of the primary processes and recycling processes for the various material flows. “This means we can precisely quantify the extent to which the recycling activities of the ALBA Group can contribute to reducing the burden on the environment,” explains Dr.-Ing. Markus Hiebel, Director of the Department for Sustainability and Participation at Fraunhofer UMSICHT. Hiebel believes that the greatest savings can be achieved if the entire value chain is aligned consistently with the circular principle: “The transformation towards a genuine circular economy requires completely new thinking. Products should be designed and managed to ensure that they contain recycled raw materials right from the start – which enables them to be recycled appropriately.”

RadiciGroup demonstrates the feasibility of industrial-scale production of polyamides (nylon) starting from bio adipic acid obtained from renewable raw materials, including waste oil and by-products of the oil industry. Potential application sectors for the process and products are textile/fashion, automotive, design, electrical and electronics.

The research was conducted through the Ulysses project and experimentation was performed in collaboration with research centres and universities. Partial funding was received from the Region of Piedmont, within the scope of the “Call for Proposals IR2 (Industrialization of research results)”. The ambitious, innovative multiyear project was launched in March 2018 and stemmed from RadiciGroup's desire to increase the sustainability of its products, whilst delivering the same quality and performance as required by product standards. What is more, the Group wanted to meet the demand coming from its various strategic sectors, in line with the European targets for the development of low-emission businesses and a circular economy.

• At this year’s INDEX from October 19th to October 22nd, Truetzschler Nonwovens, Truetzschler Card Clothing and Voith introduce new solutions for manufacturing a broad range of sustainable nonwovens for wipes, hygiene or medical textiles at booth 2327.

Plastic-free initiatives worldwide affect everyone: consumers, product developers, nonwoven producers and finally nonwoven machinery suppliers.

Truetzschler Nonwovens and Voith address the quest for more sustainable and affordable nonwovens in the wipes segment by two proven technologies for manufacturing pulp-based nonwovens. Firstly, WLS (Wet-Laid/Spunlaced) lines. More than a handful are in service worldwide and mainly target the flushable wipes market. At INDEX we’ll introduce our latest nextLevel/WLS baby and body wipes, a joint development by Voith and Truetzschler.

The second focus is on carded/pulp (CP) products. A CP line – including a TWF-NCT card placed between the HydroFormer and the AquaJet is already running to full capacity at customer site. Various CP materials, including innovative nextLevel/CP wipes, will be on display at the booth and invite visitors to discuss characteristics, benefits, line concepts and equipment.

When talking sustainable nonwovens, solutions for efficiently manufacturing biodegradable nonwovens from virgin cotton fibers, comber noils and viscose/lyocell fibers must not be missing. Visitors can look forward to directly comparing cotton nonwovens to a broad range of cellulose-based material.

Truetzschler Card Clothing, our in-house competence center with respect to card clothings and comprehensive service, presents its latest development, the Z wire for high-speed roller cards. A new geometry minimizes fiber fly and allows for better carding and more stable web forming.

Kornit Digital announced that the London-based LOVE HERO fashion label uses Kornit’s sustainable, digitized, on-demand production capabilities to deliver its complete line of nature-themed apparel.

All fabrics are traceable and certified via their blockchain platform, Retraced, to minimize their eco footprint. Cut-and-sew operations take place in Portugal.

LOVE HERO is currently engaged with Kornit on the mechanics of imprinting silk, biodegradable nylon, and other diverse materials. One such application involves two-sided fabrics—nylon on top, with cotton on the reverse.

“Kornit is committed to becoming the operating system for sustainable fashion fulfillment, on demand,” says Chris Govier, KDEU Managing Director. “With visionary creators like Joshua and LOVE HERO ready to test the bounds of our design and color capabilities, and our growing network of digitized producers ready to make those visions tangible with speed, economy, and quality from all corners of the globe, we’re changing the public percetion of what digital can do—meeting the global sustainability imperative, without demanding compromise from any actor in that value chain.”

Not only since 2021 has sustainability been a topic high on society’s agenda. And yet the importance of sustainability for consumers and companies has once again increased sharply as a result of the Corona pandemic, as numerous studies confirm. Then why is it often so difficult to implement this conviction in everyday life? One of the biggest obstacles to sustainable consumer behaviour is the lack of availability of alternatives.

In addition to changing consumer demands, the EU Commission's recent decision on the single-use plastics directive is also prompting many nonwovens manufacturers to look at alternative solutions. Kelheim Fibres is exhibiting at this year's INDEX in Geneva and online with bio-based fibers that offer an alternative to synthetic materials in a wide range of applications. The Bavarians have decades of experience in the nonwovens and hygiene sectors and work on individual customer-specific innovations.

"We want to make it easy for consumers to choose an environmentally friendly option. That’s the case when bio-based solutions offer the same performance as synthetic products," said Matthew North, Commercial Director at Kelheim Fibres." Our fibre technology allows us to create just that: unlike natural fibres, which are available already in fibre form and can only be treated on the surface, we can engineer the properties of our fibres they need for specific applications by specifically intervening in the production process. That way we combine nature - our fibres are made of wood pulp - with performance."

Kelheim's special fibres are made of wood pulp from sustainably managed sources, are produced in Kelheim in an environmentally friendly way and are fully biodegradable at the end of their product life. Kelheim Fibres is the first viscose fibre manufacturer in the world with an EMAS validated Environmental Management System and was awarded a dark green/light green shirt in the most recent Canopy HotButton-Ranking.

Korteks, one of the world’s biggest yarn producers based in Bursa, Turkey, has started the production of recycled polyester filament yarn in its production facility using a Starlinger recycling line.

With the new recycling facility, which comprises a total closed area of 17,000 m² and has a monthly production capacity of 600 tons, Korteks was able to reduce the production waste at its virgin PES yarn site to zero.

The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of Korteks’ 10 million dollars investment in a new polymer recycling facility, took up operation in May 2021. It has a production capacity of 7,200 tons per year and currently processes clean in-house polyester fibers from production scrap together with washed post-consumer PET flakes at a ratio of 50/50. Korteks uses the polyester regranulate at a share of 100 % for its new polyester filament yarn line it is going to market under the name “TAÇ Reborn”. With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

The Starlinger recycling line is the first of its kind in Turkey and is equipped with special components for filament yarn recycling. A RSC (Rapid Sleeve Changer) candle filter developed by Starlinger ensures finest melt filtration down to 15 μm. It has been specially designed for polyester recycling and reaches an output of 1000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production, which significantly limits melt loss.

The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. This makes sure that the produced regranulate has the ideal properties required for filament yarn production. The technical configuration of the line does not only allow the processing of a polyester fiber/PET flake mix as input materials, but also 100 % polyester filament scrap or 100 % PET bottle flakes.

Korteks expects the recycling market in general to grow as there is increased acceptance for recycled products in the society, and predicts the need for recycling solutions also for other synthetic and natural fibers.

• New brand Trevira CS eco

After a challenging 2020 for Trevira CS®, a year in which the coronavirus crisis put pressure on the contract market, in particular on the hotel and event sector, and also on the cruise shipping industry, the market is starting to show some signs of improvement. Numerous new developments are seizing upon the trends that have emerged since the crisis began.

Although the coronavirus pandemic had a negative effect on individual business sectors, it also has the potential to open up new market opportunities for flame retardant Trevira CS fabrics in the long run. The increase in people working from home and the longer and more frequent stay within one’s own home have led to a change in perspective in terms of the relevance of interior design. The design of the living space has undergone a revaluation. Sustainability, durability, high quality, and the desire for safe products that contain little to no harmful substances are defining criteria for selecting a new textile interior. The colour range of the new Trevira CS developments is directed specifically towards this trend and often comes across as discreet and close to nature. After Trevira CS products have found their way more and more into private homes, the new Trevira CS collections include numerous attractive textiles not only for the contract sector but also for the residential sector.

In the contract sector, notably in the hotel industry, the trends towards sustainability and quality are likely to continue to grow. Moreover, there is an increase in awareness as far as hygiene requirements are concerned. Textiles that are easy to clean without losing their appearance or their functionality can excel here. Accordingly, products ordinarily used in the healthcare sector might start to be of interest to the hotel and catering industry, public spaces, the transport industry, and to offices. This will apply in particular to areas where there is a regular flow of visitors and where people come into direct contact with fabrics. Antimicrobial textiles provide additional protection in these situations. Besides their flame retardancy, many new Trevira CS products integrate additional functions such as noise or sun protection.

Trevira has launched the Trevira CS eco brand for flame retardant textiles that consist of recycled Trevira products.
The new Trevira CS eco brand unites sustainability and flame retardancy. Trevira offers products for this which have been manufactured through different recycling processes. The flame retardant filament yarns are based on the use of recycled PET bottles (post-consumer recycling). Textiles bearing the Trevira CS eco trademark consist of at least 50% recycled materials.

Trevira uses an agglomeration facility to recycle reusable waste materials from production to manufacture recycled fibres that, after further processing, retain the same quality and performance characteristics as the original products (pre-consumer recycling).
