From the Sector

• RadiciGroup and DKB introduce the first “circular” ski suit
• A garment made of yarn obtained from recycled materials and designed with end-of-life recyclability in mind, without compromising style, design and technical performance.
• RadiciGroup Ski Club athletes will be the first ambassadors of this sustainability project

The first truly sustainable ski suit, featuring Italian style and design and a zero-kilometre supply chain, is finally here. Two Bergamo companies of excellence played the leading roles in the conception and realization of this highly innovative fashion-sport garment: RadiciGroup, a world leading producer of chemical intermediates, polyamide polymers, high-performance engineering polymers and advanced textile solutions, and DKB, a company specializing in technical sportswear with the same brand name.

The ski suit, consisting of jacket and trousers, is fashioned with a fabric made of RENYCLE, a RadiciGroup yarn obtained from mechanically recycled polyamide (nylon), which affords notable savings in energy and water consumption, as well as lower CO2 emissions. In addition, the suit’s padding and numerous accessories, such as zippers, Velcro, buttons and thread, are also made of polyamide.

This achievement was made possible by the great teamwork of RadiciGroup and DKB on the research and development of chemically compatible materials that can be used in special applications requiring high technical performance. The end result is an almost mono-material garment that significantly facilitates end-of-life recycling. It can be more easily converted into polymers for use in the manufacture of ski boot components and bindings, in addition to applications in the automotive and furnishing industries, or in any other sector requiring the characteristics of high performance polyamides.

The ski suit by RadiciGroup is thus an all-round application of ecodesign and circular economy principles to fashion and garment making, which justifies the claim “Una sostenibilità all’altezza delle nostre montagne” [Sustainability worthy of our mountains] written in a logo patch on the inside of the jacket.

“I am particularly proud of this achievement, a synthesis of my passion and effort,” said Angelo Radici, president of RadiciGroup. “I’ve always loved mountaineering and skiing, and, together with my collaborators, I work hard at our company day in and day out to find innovative solutions that improve the sustainability of our industry. This ski suit is concrete proof of the fact that textiles and apparel can be made sustainable without compromising on comfort, design, looks or performance. I will never get tired of repeating that collaboration among the firms along the production chain is crucial to manufacturing goods with an ecodesign approach, considering their end-of-life recyclability and, thus, potentially giving them unlimited durability. Upstream producers, like us, gladly share our know-how in materials chemistry and experience in recycling with our downstream partners, so that, together, we can find sustainable and viable solutions in the various sectors where we operate.”

The Chairman of the Walter Reiners-Stiftung foundation of the VDMA Textile Machinery Association, Peter D. Dornier has awarded prizes to three successful young engineers. The award-winning works provide practical solutions on the topic of circular economy. For example, the recycling of carbon fibres, which are used to produce lightweight components for the automotive industry. Or the environmentally friendly production of yarns from crab shells. Another topic was medical applications: The processing of ultra-fine yarns into stents for aortic repair. The award ceremony took place online on 9 November as part of the Aachen-Dresden-Denkendorf International Textile Conference.  

With a creativity prize, endowed with 3,000 euros, the foundation honoured the diploma thesis of Irina Kuznik, TU Dresden. She used a creative approach to realise solutions for processing chitosan into fibre yarn.

Mr Kai-Chieh Kuo was awarded the diploma/master's thesis promotion prize of 3,500 euros. With his master's thesis, which was written at RWTH Aachen University, Mr Kuo contributes to the production of vital components used in medicine. The stents made of ultra-fine yarns are made possible by an innovative modification of the classic tube weaving process.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."

• 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

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."

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.

• 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.

Combinations of variable levels of twisting and air entanglement, using up to 6 colors at once, elevate design possibilities beyond current limitations.

The ColorMind color bank features predefined colors, always in stock, meaning short lead times. Manufacturers can also benefit from customized lot sizes and bobbin length, creating even more flexibility and design freedom. To preview a taster of the potential directions opened up for loop-pile carpets, B.I.G. Yarns has used the technology to achieve its own “Optica” dot effect and “Illusion” wave effect as inspiration for customers’ design explorations.

“ColorMind offers never-seen yarn diversity to support a new level of design sophistication in high-end carpet segments. We’re very proud and excited to enter into two steps yarns with a solution offering something truly special, the result of intensive dedication from our design and development teams,” comments Emmanuel Colchen, General Manager, B.I.G. Yarns. “ColorMind combines our strengths in delivering high-performance, more sustainable yarns to fit the evolving demands of these segments, underpinned by our expertise in color sequencing and color mixing. We’re looking forward to exciting collaborations and innovative, eye-catching designs for future loop-pile carpets.”

ColorMind PA6 yarns are based on a unique Solution Dyed Nylon yarn and are suitable for Class 33 certification (heavy commercial use). The EqoCycle yarn version is mainly based on post-industrial waste and supports contract and automotive carpet manufacturers with a drop-in circular solution to reduce the ecological footprint of their end carpets.

• 75% recycled content yarn with no performance compromise
• A circular, endlessly recyclable solution for contract, automotive and residential carpets
• Significant resource efficiency in EqoCycle production compared to virgin-based PA6 yarn: 58% reduction in fossil fuel use; 27% less energy consumption; 37% CO₂ emission reduction

B.I.G. Yarns announces its latest development, EqoCycle, a fully recyclable PA6 yarn with 75% recycled content, offering the same high-quality performance of virgin PA6 yarn. The new recycled yarn mainly based on post-industrial waste supports contract, automotive and residential carpet manufacturers with a drop-in circular solution to reduce the ecological footprint of their end products.

EqoCycle is made with recycled granulates derived from pre-consumer recycled and regenerated PA6, certified by Control Union for Global Recycled Standard (GRS) Certification. The use of less virgin materials implicates a decrease of fossil fuels by 58% and a 27% decrease in energy consumption. On top, EqoCycle yarns allow a reduction of 37% of CO₂ eq./kg compared to the fossil based yarns. The environmental impacts of EqoCycle with 75% recycled content were calculated through an LCA analysis, verified according to ISO 14025 and EN 15804+A1 and published in an Environmental Product Declaration (EPD registration number S-P-02415).

Customers have the assurance that for every 1.000 tons of EqoCycle yarn, 13,562 barrels of oil are saved and 2.700 tons of CO₂ emission are reduced, compared to PA6 traditionally made from virgin materials.

Emmanuel Colchen, General Manager Yarns Division, comments: “EqoCycle is a perfect example of how higher resource efficiency in our industry can promote greater circularity in our customers’ industries. Minimizing waste, re-using materials, and saving energy and carbon emissions in production, it provides our customers and carpet brands with a new sustainable alternative that won’t compromise their end-product performance but will support their increasing focus on CO₂ reduction and global warming potential. All part of our wider commitment to encourage decoupling from the need for only virgin feedstocks and moving towards a circular economy for yarns and soft flooring industries.”

EqoCycle is the latest circular solution in B.I.G. Yarns’ PA6 portfolio, joining EqoBalance PA6, based on biomass balance renewable resources, which offers up to 75% CO₂ reduction. Both exemplify the company’s on-going investment in developing new products that better serve customers’ needs in a sustainable way. B.I.G. Yarns fully pursues opportunities to support and solve the global environmental challenges through innovation, investment and collaboration, as part of its sincere belief in, and broader commitment to, Social Responsibility.

The innovation of EqoCycle and EqoBalance PA6 aligns with the company’s active integration of the UN Sustainable Development Goals (SDGs) into its business activities, creating value for customers and engaging employees and value chain partners.

Flax has accompanied people for thousands of years, in linen fabrics, in ropes, as insulation material. And until the present day. With woven tapes made of flax, vombaur makes the functional and ecological advantages of natural fibres available for lightweight design.

Lightweight and firm
Flax fibres are particularly rigid and tear-proof. Textiles made of the natural material therefore give natural fibre reinforced plastic (NFP) special stability. Additionally, flax has a low density. The components thus combine high rigidity and strength with low weight. Another functional plus: natural fibre reinforced plastics are less prone to splintering than glass fibre reinforced plastics.

Sustainable material
The cultivation of flax binds CO2 and the production of NFP generates 33 percent lower CO2 emissions than conventional fibre reinforced plastics. The energy consumption is 40 percent lower. This reduces production costs and improves the material's CO2 footprint. Punch-packing arguments for natural fibre tapes – like flax tape by vombaur – in lightweight design applications.

Circular Economy
Circular Economy – this also works in lightweight design. The number of recycling cycles without loss of quality is higher for natural fibre reinforced plastics than for glass or carbon fibre reinforced plastics: the thermoplastic matrix of the composite can be melted and recycled after a product life cycle. The natural fibres can "live on" in other products – injection moulded products for example.

Versatile applications
"Composites from our flax tapes are used to reinforce high-tech skis as well as for extruding state-of-the-art window sections – the applications are countless," explains Tomislav Josipovic, Sales Manager with vombaur. "As a development partner, we support applications for the automotive, wind energy, construction, sports and many other industries with our composite textiles."

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.
