From the Sector

Over 600 delegates from 58 countries subscribed to the latest VDMA textile machinery webinar on sustainable dyeing held on February 3rd, 2022 – a record since the monthly online series started in June 2020. The webinar, entitled ‘Resource-saving in Textile Processing – Continuous Dyeing and Washing’, involved the three companies Monforts, DyStar® and Goller.

In outlining the capabilities of Monforts Thermex hotflue lines for the Econtrol® continuous dyeing process, the company’s Textile Technologies Engineer Jonas Beisel observed that the current industry focus is very much on cleaner processes and products in accordance with the Corporate Social Responsibility (CSR) commitments of the major fashion brands, and with further regulations to be expected.

Cellulosics
Econtrol® is a continuous process for the dyeing of woven cellulosic fabrics that has already been well proven on the market, with over 150 Monforts Thermex lines already in operation at mills worldwide.

Reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes at a temperature of between 120-130°C and a relative humidity volume of 25-30%.

Benefits
The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step.

Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

Complementary services and systems
Complementing the Monforts presentation during the webinar, Bertram Seuthe, Global Business Development Manager at DyStar, outlined the importance of specific Levafix® /Remazol® reactive dyes and Dianix® disperse dyes for sustainable dyeing processes such as Econtrol®, Cadira® Continuous and CPB knit. In these processes Sera® auxiliaries are also employed for optimised wash-off results.

Guido Seiler, Area Sales Manager at Fong's Europe, also introduced the latest developments of the Goller brand for the washing process, which can reduce water consumption by between 10 to 20%, as well as reductions in both heating energy and waste generation, depending on the specific fabric construction and required shade.

For the second time in a row, the speciality viscose fibre manufacturer Kelheim Fibres was awarded a place on the podium at the Cellulose Fibre of the Year Awards. The concept for sustainable menstrual underwear made from Kelheim’s functionalised speciality fibres achieved third place. Kelheim Fibres thus emerges from the competition as the most innovative fibre manufacturer.

Project manager New Business Development Natalie Wunder presented the promising concept from Kelheim at the International Conference on Cellulose Fibres: "We have been able to use our experience as a long-established supplier for the tampon industry to develop further sustainable solutions in the feminine hygiene sector, in this case reusable menstrual underwear. As an innovation pioneer, we are thus helping to break the taboos that surround the topic of menstruation. We offer women the choice between different environmentally friendly products which also offer high levels of performance - depending on what fits their lifestyle."

For the next step, the commercialisation of the concept, Dr Marina Crnoja-Cosic, Director New Business Development at Kelheim Fibres, puts her trust in the proven open innovation approach: "We want to bring partners from the entire value chain together. By bringing in our joint expertise, we can significantly accelerate the path from idea to finished product in the market. At the same time, through open dialogue, we ensure that the concept works seamlessly from fibre through processing to the final product.

Over 400 employees work hard every day to improve the environmental performance of Radici Yarn’s site. Through teamwork and continuous improvement in energy efficiency, Radici Yarn has obtained ISO 50001 Energy Management Systems certification, which attests to the organization’s commitment to contain and progressively reduce energy consumption.

Radici Yarn, one of the companies in the RadiciGroup Advanced Textile Solutions Business Area, is engaged in the production and sale of polyamide 6 polymer, PA6 and PA66 continuous filament and staple yarn, and other synthetic fibres, including products made of recycled or bio-based materials.

All the processes - polymerization and spinning (Villa d'Ogna plant), as well as warping and draw-warping (Ardesio plant) - are run under constant monitoring with the goal of achieving maximum energy efficiency and lower consumption. Both sites are powered by two hydroelectric power plants owned by Geogreen, a RadiciGroup partner and energy supplier. The share of energy consumption from renewable sources and reduced environmental impact (natural gas) sources  is constantly increasing.

The energy issue has always been a priority for Radici Yarn, whose products serve numerous sectors, including automotive, clothing and furnishings.

"Already at the beginning of the 1990s, Radici Yarn started investing in cogeneration, the simultaneous production of electricity and steam,” pointed out Laura Ravasio, energy manager of Radici Yarn SpA. “We have recently started up an advanced trigeneration plant – a highly efficient system that produces not only electricity and steam, but also chilled water for our production processes. One of the first results recorded in 2021 was a 30% reduction in water consumption. Thus, ISO 50001 certification seemed like the next logical step to take in formalizing a long-term approach to energy.”

The ISO 50001 certification, which is voluntary and valid for a period of three years, was added to the ISO 14001 Environmental and ISO 9001 Quality Management system certifications previously achieved by Radici Yarn.

• Hexcel HexPly® XF Selected for High-Quality, Paint-Ready Parts for Sunseeker 90 Ocean Luxury Yacht
• Hexcel’s innovative surface technology yields parts with paint-ready surfaces for builder of luxury yachts

Yacht builder Sunseeker has chosen Hexcel’s HexPly® XF surface technology to produce prepreg parts with high-quality, paint-ready surfaces quickly and efficiently for its 90 Ocean luxury yacht, one of its newest models.

The lightweight composite hardtop for the Sunseeker 90 Ocean yacht is manufactured from a combination of HexPly® XF and Hexcel's HexPly® SuperFIT® semi-preg. The hardtop is lighter in weight than versions made using resin-infusion processes, and it de-molds with a pinhole-free surface that needs minimal preparation to be ready for paint. Sunseeker has recorded an overall reduction in process time of around 30%, saving three days of manufacturing time per hardtop.

The hardtop provides shade and protection for the yacht’s uppermost deck space. Its reduced weight helps to ensure the stability of the vessel, and the paint-ready finish with HexPly XF provides Sunseeker with more options for customizing its color to the individual needs of its clients.
 
HexPly XF is a lightweight, non-woven semi-preg that eliminates the need to use a traditional in-mold gel coat. The innovative surface technology significantly reduces the costly and time-consuming refinishing work typically required to impart a paint-ready finish to prepreg or semi-preg parts, and yields lightweight, consistent components in short cycle times.

Working with Sunseeker, Hexcel developed a material format, a laminate ply sequence, and a production process that satisfied the structural requirements for the hardtop and enabled the yacht builder’s production team to lay up and cure the part in a single shot – slashing cycle times.

Hexcel supplies Sunseeker with a HexPly XF product that comprises both the surface layer and the first structural reinforcement ply, eliminating the need for a cosmetic barrier coat. Neither the HexPly XF surface layer nor the following layers of HexPly SuperFIT require time-consuming debulking steps – significantly reducing lay-up time – and both are based on Hexcel's rapid-curing M79 epoxy resin system. Adhesive resin films are not needed to bond the hardtop’s foam core, as the resin content of the SuperFIT plies has been adjusted to further reduce overall process time.

Once de-molded, the cured hardtops are inspected before they are passed to Sunseeker’s finishing and painting technicians for final preparation and painting. The HexPly XF resin surface allows the yacht builder’s quality technicians to inspect the laminate below quickly and easily, ensuring the quality and consistency of the structural reinforcement plies.

“Composite materials that improve our production processes, as well as great technical support, are what makes working with Hexcel such a success story," said Stuart Vaughan-Jones, Composite Development Manager, Sunseeker. "With the switch from gel coat and resin infusion to HexPly XF and SuperFIT in the new hardtops, we are now building lighter, more consistent parts, more quickly than before, with a higher quality surface finish. XF really has ticked all the boxes.”  

Garth Thomas, Account Manager – Marine, Hexcel, said: "With the HexPly XF surface technology now well established, XF will soon be used in other large moldings where minimizing weight is critical, as well as additional hardtops across the Sunseeker model range."

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.

That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.

• The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free* PURE INDIGO ICON dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.
• The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.
• The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as INDIGO REFLECTION or PURE UNDERTONES.

Umberto Devita, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, comments: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”

For Jean-Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”

Kornit Digital Ltd. announced that Portuguese textile specialist Blur has installed the Kornit Presto S with Softener solution for sustainable, single-step direct-to-fabric production of multiple fabrics in any quantity. The print services provider, which supports the production needs of high fashion brands has previously installed multiple Kornit Atlas and Avalanche systems for industrial-scale digital direct-to-garment (DTG) production on demand.

Using Kornit’s efficient, eco-conscious, proprietary technology and consumables, Blur provides rapid fulfillment of orders ranging from a single piece to mass production, with an average order of about 500 items. Since implementing the Kornit Presto S, the system has been in operation day and night, producing samples during normal business hours and fulfilling diverse incoming orders overnight.

Mariano Dias, CEO at Blur, believes Kornit technology empowers his business to adapt quickly to the constantly evolving needs of his clients, which include both larger established brands seeking large quantities and ambitious designers seeking to build a brand with limited risk or investment. In many cases, they are fulfilling different types of designs for clients serving both Europe and North American markets.
“The quality is just outstanding, and some clients only want to print with Kornit technology”, said Dias. “We are extremely happy with Kornit’s collaboration, and our printers are working perfectly around the clock. Any textile printing company looking to move into fashion and work with famous brands will need both roll-to-roll and DTG capabilities. Our recommendation for success is to buy the Kornit Atlas and Kornit Presto printers.”

He added that Blur’s success with its current Kornit systems, as well as increased demand for sustainably-produced textiles, has the business considering the addition of a second Kornit Presto S to accommodate additional volumes.

“As with many of our customers, Blur was built around more traditional textile operations—in their case embroidery—before discovering the vast potential for growth and versatility offered by quick, efficient, digital production on demand,” said Chris Govier, Kornit Digital Europe, Middle East, and Africa President. “Whether you’re serving an internationally-known fashion house looking for more agile fulfillment and simpler supply chains, or the independent creator hoping to bring unique inspirations to life, Kornit’s product portfolio offers continuous opportunities to answer market needs, create new markets, and scale upwards under any conditions.”

• The Green Revolution: How Microfactories Can Change the Face of Fashion by Mark Sollman, Product Manager EMEA, Mimaki Europe

With the all-important COP26 Climate Change Conference having taken centre stage in November, there is no time like the present for the fashion world to rally together in stepping up sustainability efforts and getting carbon emissions under control. Globally, the fashion industry is now estimated to account for around 10 percent of greenhouse gas emissions and 20 percent of wastewater , making the pursuit of greener production methods more pertinent than ever before. Thankfully, we are seeing a new era of production enter the fashion arena, with the increasing emergence of technologically advanced, highly automated microfactories.

Along with reducing unnecessary waste through on-demand production, microfactories have a smaller ecological footprint than traditional garment production and require no water use during the production process, making it not only a faster solution, but a greener one too.

Last year’s FESPA saw Mimaki team up with fashion designer Carolina Guzman to bring her designs to life in real time at the show, setting up its own working microfactory live on-site to take her designs from screen to garment within just a day. Guzman’s designs were created using Mimaki’s TS100-1600 Sublimation Printer, before being transferred to textile, digitally cut and finally pieced together. Devised with a string of ethical and environmental objectives threaded throughout, the microfactory also exclusively utilised eco-friendly Greentex fabric, and any remaining material was donated to Sheltersuit: a wind- and waterproof coat that can be transformed into a sleeping bag, which is provided free of charge to homeless people and refugees.

Through working with a number of strategic partners – including transfer printing expert, Klieverik; paper solutions specialist, Neenah Coldenhove; and digital cutting equipment provider, Summa – Mimaki was able to produce a collection of unique, high-quality garments live on the stand during the tradeshow, demonstrating to visitors from more than 100 countries some of the key reasons that microfactories seem set to change the future of fashion…

Unparalleled speed and versatility
Where traditionally, apparel manufacturing has centred on a production chain model of sourcing materials and producing garments in bulk, microfactories are now enabling on-demand, on-location production, making it possible to create everything from unique, one-off pieces and samples right through to entire product lines – all at unprecedented speeds. This means greater flexibility and customisation, enabling designers to modify or update designs and respond to market trends as they occur.

Simplified supply chains and minimised risk
The microfactory setup brings production in-house and on-demand, minimising the cost of not only storing stock, but also of shipping it and responsibly disposing of unsold items. Where recent geopolitical events have highlighted the fragility of global supply chains, microfactories offer a unique independence from these systems, empowering garment manufacturers to future-proof their businesses, become less reliant on external systems and suppliers, and reduce the risk of disruptions.

A boosted bottom line and a greener future
Facilitating savings in a whole line of resources, from physical storage and production space to time and energy, microfactories ultimately have the potential to significantly increase profitability for garment manufacturers, with the additional benefit of being easily scalable as production increases. Perhaps even more compelling, however, are the environmental considerations. Demonstrated on a small scale through Mimaki’s recent project, the environmental benefits inherent to microfactory production will have an even greater impact as it becomes more prolific and commonplace throughout the fashion world, with the potential to effect meaningful environmental change as adoption increases in the years to come.

• More than 30 leading pioneers of the chemical and material sector welcome the latest political papers from Brussels, Berlin and Düsseldorf

The political situation for renewable carbon from biomass, CO2 and recycling for the defossilisation of the chemical and materials industry has begun to shift fundamentally in Europe. For the first time, important policy papers from Brussels and Germany take into consideration that the term decarbonisation alone is not sufficient, and that there are important industrial sectors with a permanent and even growing carbon demand. Finally, the need for a sustainable coverage of this carbon demand and the realisation of sustainable carbon cycles have been identified on the political stage. They are elemental to the realisation of a sustainable chemical and derived materials industry.

The goal is to create sustainable carbon cycles. This requires comprehensive carbon management of renewable sources, which includes carbon from biomass, carbon from Carbon Capture and Utilisation (CCU) – the industrial use of CO2 as an integral part – as well as mechanical and chemical recycling. And only the use of all alternative carbon streams enables a true decoupling of the chemical and materials sector from additional fossil carbon from the ground. Only in this way can the chemical industry stay the backbone of modern society and transform into a sustainable sector that enables the achievement of global climate goals. The Renewable Carbon Initiative’s (RCI) major aim is to support the smart transition from fossil to renewable carbon: utilising carbon from biomass, CO2 and recycling instead of additional fossil carbon from the ground. This is crucial because 72% of the human-made greenhouse gas emissions are directly linked to additional fossil carbon. The RCI supports all renewable carbon sources available, but the political support is fragmented and differs between carbon from biomass, recycling or carbon capture and utilisation (CCU). Especially CCU has so far not been a strategic objective in the Green Deal and Fit-for-55.

This will change fundamentally with the European Commission's communication paper on “Sustainable Carbon Cycles” published on 15 December. The position in the paper represents an essential step forward that shows embedded carbon has reached the political mainstream – supported by recent opinions from members of the European parliament and also, apparently, by the upcoming IPCC assessment report 6. Now, CCU becomes a recognised and credible solution for sustainable carbon cycles and a potentially sustainable option for the chemical and  material industries. Also, in the political discussions in Brussels, the term “defossilation” is appearing more and more often, complementing or replacing the term decarbonisation in those areas where carbon is indispensable. MEP Maria da Graça Carvahlo is among a number of politicians in Brussels who perceive CCU as an important future industry, putting it on the political map and creating momentum for CCU. This includes the integration of CCU into the new Carbon Removal Regime and the Emission Trading System (ETS).

As the new policy documents are fully in line with the strategy of the RCI, the more than 30 member companies of the initiative are highly supportive of this new development and are ready to support policy-maker with data and detailed suggestions for active support and the realisation of sustainable carbon cycles and a sound carbon management. The recent political papers of relevance are highlighted in the following.

Brussels: Communication paper on “Sustainable Carbon Cycles”
On 15 December, the European Commission has published the communication paper “Sustainable Carbon Cycles” . For the first time, the importance of carbon in different industrial sectors is clearly stated. One of the key statements in the paper is the full recognition of CCU for the first time as a solution for the circular economy, which includes CCU-based fuels as well. The communication paper distinguishes between bio-based CO2, fossil CO2 and CO2 from direct air capture when addressing carbon removal and it also announces detailed monitoring of the different CO2 streams. Not only CCU, but also carbon from the bioeconomy is registered as an important pillar for the future. Here, the term carbon farming has been newly introduced, which refers to improved land management practices that result in an increase of carbon sequestration in living biomass, dead organic matter or soils by enhancing carbon capture or reducing the release of carbon. Even though the list of nature-based carbon storage technologies is non-exhaustive in our view, we strongly support the paper’s idea to deem sustainable land and forest management as a basis for the bioeconomy more important than solely considering land use as a carbon sink. Surprisingly, chemical recycling, which is also an alternative carbon source that substitutes additional fossil carbon from the ground (i.e. carbon from crude oil, natural gas or from coal), is completely absent from the communication paper.

Berlin: Coalition paper of the new German Government: “Dare more progress – alliance for freedom, justice and sustainability”
The whole of Europe is waiting to see how the new German government of Social Democrats, Greens and Liberals will shape the German climate policy. The new reform agenda focuses in particular on solar and wind energy as well as especially hydrogen. Solar energy is to be expanded to 200 GW by 2030 and two percent of the country's land is to be designated for onshore wind energy. A hydrogen grid infrastructure is to be created for green hydrogen, which will form the backbone of the energy system of the future – and is also needed for e-fuels and sustainable chemical industry, a clear commitment to CCU. There is a further focus on the topic of circular economy and recycling. A higher recycling quota and a product-specific minimum quota for the use of recyclates and secondary raw materials should be established at European level. In the coalition paper, there is also a clear commitment to chemical recycling to be found. A significant change for the industry is planned to occur in regards to the so-called “plastic tax” of 80 cents per kilogram of non-recycled plastic packaging. This tax has been implemented by the EU, but most countries are not passing on this tax to the manufacturers and distributors, or only to a limited extent. The new German government now plans to fully transfer this tax over to the industry.

Düsseldorf: Carbon can protect the climate – Carbon Management Strategy North Rhine-Westphalia (NRW)
Lastly, the RCI highly welcomes North Rhine-Westphalia (NRW, Germany) as the first region worldwide to adopt a comprehensive carbon management strategy, a foundation for the transformation from using additional fossil carbon from the ground to the utilisation of renewable carbon from biomass, CO2 and recycling. For all three alternative carbon streams, separate detailed strategies are being developed to achieve the defossilisation of the industry. This is all the more remarkable as North Rhine-Westphalia is the federal state with the strongest industry in Germany, in particular the chemical industry. And it is here, of all places, that a first master plan for the conversion of industry from fossil carbon to biomass, CO2 and recycling is implemented. If successful, NRW could become a global leader in sustainable carbon
management and the region could become a blueprint for many industrial regions.

Over the past 14 days, the wholesale cost of natural gas in Germany has risen by more than 50%. This increase presents an extraordinary challenge for industry, and there is no sign of support or intervention from the Government. Indeed, recent statements are destined to provoke a worsening of the situation.

Kelheim Fibres is entirely dependent on natural gas for the generation of electrical energy and steam and has no viable short-term alternatives. In addition, the raw materials used by the company often consume high levels of energy in their production and are also increasing significantly in cost. These increases in cost jeopardise the future of the business if they cannot be passed on though the supply chain.

Kelheim Fibres is calling on the Government of Germany to take immediate steps to mitigate the impact of the cost increases for natural gas and is committed to work to implement alternative sources of energy in the medium term.

In parallel, the disruption to global logistic networks that has been seen throughout 2021 is now expected to continue throughout 2022. Massive increases in shipping rates – in some cases in excess of 80% – are being imposed without notice and with no opportunity for negotiation. These costs must also be passed on though the supply chain if businesses are to remain viable.

To address these issues, Kelheim Fibres is implementing the following measures with immediate effect:

• The increased cost of energy and freight will be passed on in prices to customers at the soonest opportunity;
• If necessary, changes or adjustments to existing agreements will be negotiated to reflect the increased cost levels;
• If the necessary increase in fibre prices cannot be secured, cuts to production will be implemented with the objective of minimising losses until the cost increases can be mitigated.

As the drivers for the increases in natural gas prices appear to be temporary in nature, we will maintain any price adjustments under review and pass on any relief to customers.

Craig Barker, CEO of Kelheim Fibres, describes the current situation as critical. “The cost increases we are facing are unprecedented and call for swift and decisive action. We are determined to take the necessary steps to preserve the future of our business and provide security of supply for our customers. At the same time, we are relying on the support of our customers to help us conquer the challenges our business is facing.”

Kornit Digital Ltd. announced that France-based Brodelec has recently complemented its existing Kornit Avalanche direct-to-garment (DTG) and Kornit Presto S direct-to-fabric print systems with Kornit Atlas MAX technology. The print services provider, which produces personalized markings on textiles, luggage, and promotional pieces, has used Kornit Digital production technologies for more than 15 years.

Tourism accounts for 30% of Brodelec’s business, and clients include zoos, museums, and tourist attractions, as well as communication agencies. They established an on-demand web platform enabling small brands and YouTube users to order and receive custom gear quickly. By investing in a broad cross-section of Kornit’s technologies for single-step, eco-friendly, just-in-time production, Brodelec creates new opportunities and sales channels, which proved fortuitous when the pandemic economy suddenly impacted consumer behaviors.

Using Kornit’s Oeko-Passport and GOTS-certified inks, these systems produce consistent, high-quality impressions within minutes, giving Brodelec the flexibility to produce a variety of applications, in multiple materials, with a single ink set. The business complemented Kornit’s quick, efficient production capabilities with a laser cutting system and several sewing machines, empowering them to offer finished pieces such as imprinted cushions, tote bags, aprons, and towels.
