From the Sector

• ECOSENSOR™’s new references combine high-performance and innovation to empower people with the possibility to live life naturally both for mind and body.
• The new range is woven from certified ingredients, a completely traceable production process and highly certified suppliers               

"A New Eco high-tech force of Nature", a bold claim, a daring attitude and true facts. ECOSENSOR™ by Asahi Kasei has concentrated all its key values into a Nature-driven and high-tech fabric collection that respects the environment and human being.

Sustainability, active climate control, exquisite touch and extreme performance co-habit the textiles: the collection is made of wovens and knits where the main technology is represented by GRS - Global Recycle Standard certified polyamide and polyesters, sometime combined with ROICA™ recycled stretch yarns and dyed and finished with Oekotex Standard 100 certified processes and/or by BlueSign® partners’ companies.

But there is much more than it meets the eye.

Behind the new collection is a great story of sustainability.

"Our international team strives to innovate with a human-based approach to research and develop solutions that meet high-performance standards as well as the transparency and traceability of both the ingredients and the supply chain", says Mr. Hashimoto, Senior Managing Director of Asahi Kasei Advance, the global materials innovator and manufacturer.

Indeed, the company has set the high bar all its suppliers and partners must match. Such criteria include: thoroughly transparency and traceability of both materials and production, corporate responsibility at all levels and a strategic commitment granted by influential certifications such as GRS - Global Recycle Standard for recycled ingredients and processes, as well as Bluesign® and OekoTex Standard 100 certifications, which focus on environmentally-friendly impact of the dyeing and finishing processes.

The human, environmentally-friendly and cutting-edge imprint of ECOSENSOR™ ultimate collection reflects a vision for a more responsible way of fabric manufacturing.

A new force of nature, because story telling truly must match the story making.

The coronavirus pandemic and its massive impact on the automotive industry led to an un-precedented market slump in the first half of 2020 and a corresponding revenue decline at Autoneum. Revenue in local currencies fell by –32.7% compared to the prior-year period, and in Swiss francs by –36.8% to CHF 730.6 million. The turnaround program for the North American sites made further progress in the first six months and is showing the targeted results. However, they were clearly overcompensated by the massive impact of the corona-virus crisis, which led to a negative net result of CHF –54.9 million despite comprehensive cost flexibilization measures.

Like the entire automobile industry, Autoneum was massively impacted by the effects of the corona-virus pandemic in the first half of the year. The temporary plant closures at almost all customers in every region, especially in the second quarter of the year, not only led to an unprecedented market collapse, but also to a production stop at all 55 Autoneum sites. Starting in February in China and one month later in all other regions, vehicle manufacturers temporarily shut down production completely. The corresponding massive drop in global vehicle production led to a slump in revenue at Autoneum of –32.7% in local currencies. This reflects the development of the market in the first half of 2020, which contracted by –33.2% year-on-year. Revenue in Swiss francs at Autoneum fell by –36.8% to CHF 730.6 million (prior-year period: CHF 1 156.1 million). Revenue development in all Business Groups outperformed the respective markets, particularly in Asia and the SAMEA (South America, Middle East and Africa) region.

 Like the entire automobile industry, Autoneum was massively impacted by the effects of the corona-virus pandemic in the first half of the year. The temporary plant closures at almost all customers in every region, especially in the second quarter of the year, not only led to an unprecedented market collapse, but also to a production stop at all 55 Autoneum sites. Starting in February in China and one month later in all other regions, vehicle manufacturers temporarily shut down production com-pletely. The corresponding massive drop in global vehicle production led to a slump in revenue at Autoneum of –32.7% in local currencies. This reflects the development of the market in the first half of 2020, which contracted by –33.2% year-on-year. Revenue in Swiss francs at Autoneum fell by –36.8% to CHF 730.6 million (prior-year period: CHF 1 156.1 million). Revenue development in all Business Groups outperformed the respective markets, particularly in Asia and the SAMEA (South America, Middle East and Africa) region.

Autoneum promptly responded to the pandemic-related market slump by adopting extensive cost-cutting measures in all regions. These include the reduction of employee costs by, among other things, adjusting time accounts, introducing short-time work at eligible locations and temporary layoffs as well as headcount reduction, mainly among temporary workers. In addition, operating expenditures were limited to the absolutely necessary. The investment volume for 2020, already reduced from previous years, was downsized even further. Autoneum continues to benefit in this regard from the high level of investments undertaken in recent years.

 Although the coronavirus crisis and the measures taken to contain it dominated Autoneum’s course of business in the first half of 2020, the Company achieved necessary operational and financial im-provements during this period. The comprehensive turnaround program for the North American sites made further progress and is on track. Efficiency improvements already achieved there had a posi-tive effect on the figures of the first half-year, but were significantly overcompensated by the substan-tial impact of the COVID-19 crisis. Savings and cost flexibilization measures taken immediately and implemented worldwide in view of the revenue loss could not offset the ongoing, capacity-related fixed costs. This led at the Group level to a negative EBIT of CHF –31.8 million (prior-year period: CHF 16.4 million), which equates to an EBIT margin of –4.4% (prior-year period: 1.4%). The net result decreased because of the severe revenue shortfall to CHF –54.9 million (prior-year period: CHF –6.0 million).

Outlook
For 2020 Autoneum expects revenue to develop at market level. Although customers’ production volumes should increase again in the second half of 2020 compared with the first semester, latest fore-casts indicate that they will remain clearly below the level of the second half of 2019. Immediately implemented and ongoing cost reduction measures as well as further operational optimizations also within the turnaround program in North America will lead to improvements in the second half of the year. Due to the current uncertainties, a reliable statement on the net result for the full year 2020 thus cannot be made. With regard to the mid-term targets, a recovery of the profitability level is expected, but it will largely depend on the market development.

• Specialised in dye-sublimation printing, the Italian company has conquered the heights of the high fashion sector with its top-quality printed fabrics.
• With its recent investment in a direct-to-fabric printing line, Digitak is preparing to expand its range of printed products, focusing on fabric differentiation.

Dye sublimation printing of high fashion designs is the beating heart of Digitak, an Italian company specialised in digital textile printing. Operating in the textile district of Lombardy, Italy, the company has established itself among the main suppliers in the world of high fashion and sportswear in just under 15 years.

Making production versatility one of the cornerstones of its philosophy, Digitak has continued to invest in technology, as well as research and development its product portfolio. This forward-thinking approach has enabled the company to guarantee innovative, personalised products with meticulous attention to detail, with the highest – almost obsessive – standards of quality and maximum design flexibility. Over the years, the extensive experience gained by the company’s management in the field of sublimation with traditional and digital techniques, combined with their investment decisions have allowed Digitak to enhance its production performance, gradually implementing higher quality standards and differentiating itself from the competition in the complex and competitive sector of high fashion. An important feat, which has not, however, dampened its enthusiasm and willingness to continue growing and exceeding its goals. The company’s latest investment in a direct-to-fabric digital printing line with pigment ink propels the company into a new and promising production dimension.

Sublimation printing specialists

Since Digitak’s establishment, Filippo Taccani, the founder and current owner of the company, had set himself a clear and ambitious objective: “I wanted to take up the challenge of operating digitally - printing fabrics using this innovative technology to create products on a par with those  I had achieved with traditional sublimation textile printing methods during my previous work experience.”

The purchase of a Mimaki JV4 plotter, one of the first to be installed in Italy, marked the beginning of Digitak’s adventure. “To start the business, I needed a printing system that could operate with dispersed inks to print on polyester and I found the JV4 to be the best option,” explains Taccani. “It was an excellent decision, because I used these plotters to build the company and its success.”

The first Mimaki plotter was in fact followed by a second and a third. When it bought the fifth, the company moved to an industrial unit in Tradate (Varese) – Digitak’s current site – which now houses around fifteen Mimaki JV33 plotters, in addition to three Mimaki TS500-1800 wide-format sublimation printers, and a Mimaki TS300P-1800 high-speed sublimation printer. This Mimaki powered production facility – which is one of the company’s core strengths – was recently expanded with the addition of a Mimaki TX300P-1800B belt-type hybrid printing system, together with a Mimaki TR300-1850C textile coater and a Mimaki Tiger-1800.

“Naturally, over the years, we have also tested printing systems from other suppliers, but we have always returned to Mimaki. With high fashion as our key market, we need to guarantee our customers the highest levels of quality and, to date, we have never found solutions that beat the quality of this Japanese brand’s technology.”

According to Taccani, the difference lies in the “calligraphy” of Mimaki’s machines, that is the line of the ink on the fabric: “Unlike its competitors, Mimaki has focused on the ‘waveforms’, i.e. the electronics associated with the print heads. This attention paid to the way the ink jet is managed from the print head has allowed Mimaki to achieve unparalleled levels of accuracy, an aspect that has given my company a clear competitive edge.”

Moreover, at Digitak, quality comes before quantity: “We prefer to dedicate an extra day to production to guarantee the customer a final product that fully meets requirements and expectations. Mimaki’s technology not only suits this business model bult on top quality, but it crucially enables it.”

Operational and creative flexibility

Digitak currently prints around 2,000 linear metres of fabric per day. Its portfolio ranges from clothing and scarves, to beach and swimwear, with related personalised accessories, to sportswear, with technical properties such as breathability, comfort, resistance to external agents. The company have even added customised outdoor furniture to their offering of diverse and creative products.
The company’s machines operate continuously, 24/7. During the day, the machines are mainly used to develop and produce samples and colour proofs, while the actual production is carried out at night. “Thanks to our technology, we have developed an extraordinary operational flexibility. The fact that we have so many plotters allows us to work on multiple designs at the same time and to launch projects that are also very different from one another,” explains Taccani. “There are also some other crucial factors that have contributed, and continue to contribute, to increasing our production efficiency. The reliability of Mimaki’s solutions and the remote monitoring option offered is key. Once the standard start-up monitoring has been carried out and the machines are found to be printing correctly, we can let them work overnight without an operator. This is a great benefit for people who, like us, manage such a large and diverse fleet of machines.”

Digitak takes the same approach to customer service. Faced with an increasingly demanding market in terms of creativity, precision and completeness of service, the company wants to guarantee flexibility and customisation. “We decided to set up a department dedicated to the pre-press stage, in charge of preparing and checking the files supplied by customers. Seldom do our teams not need to do some editing of the files supplied, even if it’s only to make small changes that are essential for the print document to be as suitable as possible and to achieve the best final result.”

Technologies of the future

With a view to further enhancing production and customer service, Taccani has chosen to take on a new challenge, switching things up with some of the most recent investments.

While maintaining the focus on dye sublimation printing, Taccani has focused on technological diversification by installing a direct-to-fabric digital printing line. This consists of a Mimaki TX300P-1800B printing system with pigment inks and a TR300-1850C coater from Mimaki’s TR series. “The market continues to evolve and now requires even more flexibility regarding both processes and the fabrics supplied. This means that great opportunities exist for a print shop capable of simultaneously producing the same design – with minimal colour adjustment – on different fabrics, guaranteeing similar and accurate results. And this is precisely the path we are taking,” says Taccani. “Why have we opted for Mimaki again? Well, I had an opportunity to try out their new pigment inks and I immediately realised that they are a generation ahead of the other pigments available on the market. The cyan is very clean, the black is deep and there is a very interesting fullness of colour, suitable not only for furnishings, but also for other applications in the clothing sector.”

With its pigment inks, the new direct-to-fabric printing line allows Digitak to explore other related market segments. Thanks to the innovative automatic belt system, the TX300P-1800B guarantees good productivity and high-quality results. A standard of quality that is also boosted by the TR300-1850C fabric pre-treatment system: “This coater is essential for ensuring the best possible preparation of fabrics for printing. In fact, we are able to treat fabrics to make them suitable for the type of print they are intended for, sanitise them for specific applications and, in some cases, even dye them, with excellent quality.”

According to Taccani, another beneficial factor of direct-to-fabric pigment printing technology is the eco-sustainability of the process and its lower environmental impact. “We are proud to be able to offer our customers excellent printing results using little water and printing in ‘green mode’, with both the technologies we have available. I consider them winning technologies for the future, as both dye sublimation printing and direct-to-fabric printing with pigment inks use little water while mainly requiring the use of energy. Therefore, if you use renewable energy, then you’re done.”

Digitak’s other trump card is the Tiger-1800 installed in 2019. With this industrial printing system, the company aims to increase production volumes while maintaining its high-quality standards and further optimising costs. “We are excited to have these promising technologies available to us in-house. We are currently experimenting with these solutions, testing new opportunities and evaluating which paths to take to stay ahead of the game,” concludes Taccani.

Sustainable solutions that pack a punch  

With over 6,500 visitors and more than 2,000 participants at a total of 720 minutes of live presentation sessions and with many potential new customers in the live info chat, the virtual interpack conference organised by Sappi was a resounding success. Sappi presented its latest developments, future prospects and current range of packaging and speciality papers at the event. In addition to further networking opportunities, the visitors took full advantage of the chance to get in contact with the Sales team.

• For the packaging of the future: sustainable, high-quality paper
• Second-generation barrier papers ensure optimal protection of goods as food packaging

Shanghai – Sateri has unveiled FinexTM as its new product brand for recycled fibre. FinexTM, short for ‘Fibre Next’, is an innovative next-generation cellulosic fibre containing recycled content. Internationally known outdoor brand Lafuma has produced FinexTM apparel ahead of 618, China’s major mid-year online shopping festival, while independent China designer Rico Lee will launch his FinexTM apparel next month.

Since its announcement in March this year of a breakthrough in commercial production of viscose using recycled textile waste, Sateri has worked closely with its downstream yarn and garment manufacturing partners to bring the recycled fibre product to the consumer market.

“We’re pleased to collaborate with Sateri as one of their first brand partners for FinexTM. Sateri’s dedication to this partnership made it possible for Lafuma to produce T-shirts with this fine quality fibre in a short time. T-shirts made with FinexTM will be among the offerings Lafuma has in store for the 618 festival as we look to support environmentally-friendly and excellent performance solutions to strengthen our position as a leading outdoor apparel brand,” said Wu Qian, General Manager of Lafuma China.

Echoing similar sentiments is Rico Lee who established his own independent label in 2014, “I jumped at the opportunity to collaborate with Sateri when they approached me because FinexTM encapsulates what my brand stands for – Beautiful Technology that combines function and fashion.”

Tom Liu, Sateri’s Commercial Vice President said, “Like our flagship brand EcoCosy®, FinexTM is made from bio-based natural fibres. Innovation and technology has made cellulosic textile fibre recycling possible and FinexTM represents how nature not only renews itself but that products made from nature can also be regenerated. This, at its heart, is what circular fashion looks like. Our brand promise to customers remains constant– Sateri’s products are sustainable, high quality, efficient, and cost-effective. The FinexTM tagline ‘Together For A Better Next’ expresses our aspiration to be the partner of choice for next-generation fibre - we thank Lafuma and Rico Lee for pioneering with us on this quest.”

Last month, Sateri announced its entry into China’s Lyocell fibre market. The recent string of product portfolio expansion announcements is underpinned by Sateri’s business strategy to capture value. Allen Zhang, President of Sateri said, “Being the world’s largest viscose producer gives us the advantages that come with volume, but value is what we hope differentiates us. By this, we don’t only mean higher value products like Lyocell or FinexTM but also the value we bring to communities, country, climate and customers.”

Globally, less than 1% of material used to produce clothing is recycled into new clothing. This presents a big opportunity for textile fibre recycling, particularly in China which is the largest textile producing country in the world. Last month, Sateri became a council member of the China Association of Circular Economy (CACE). The company will work closely with CACE’s Textile Waste Comprehensive Utilisation Committee to establish standards and promote industrial-scale textile waste recycling. Sateri is part of the Singapore-based RGE group of companies which has committed USD200 million into next-generation textile fibre innovation and technology.

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

In der Corona-Krise ist eine Entwicklung des Thüringischen Instituts für Textil- und Kunststoff-Forschung (TITK) derzeit besonders gefragt: die antimikrobiell wirksame Cellulose-Faser mit Silber-Ionen. Die smartpolymer GmbH, ein Unternehmen der TITK-Gruppe, stellt sie auf einer Pilotanlage unter dem Namen Cell Solution bioactive her. Abnehmer sind unter anderem die Hersteller von Atemschutzmasken.

Die natürliche antibakterielle Wirkung von Silber wird seit Jahrhunderten zur Entkeimung genutzt. Durch Anreicherung mit dem Edelmetall – bis zu 6 Prozent Silbergehalt sind einstellbar – kann die Cellulose-Faser aus Rudolstadt gerade in Krankenhäusern oder Hygienebereichen einen wertvollen Beitrag zum Schutz vor unerwünschten Keimen leisten. Nach der Verarbeitung zu einem Vlies lässt sie sich unter anderem als eine Lage in Atemschutzmasken integrieren.

„Die Faser wirkt antibakteriell und fungizid – tötet also Keime und Pilze sehr zuverlässig ab“, erläutert Dr. Frank Wendler, der bei smartpolymer die Forschung und Entwicklung der Cell Solution-Funktionsfasern verantwortet. Hierbei handelt es sich um Lyocell-Fasern*, die mit verschiedensten Zusatzfunktionen ausgestattet werden können. Das Besondere: Die Wirkstoffe werden durch ein patentiertes Verfahren direkt in die Faser eingebracht. „Dadurch erreichen wir einen Depot- und einen so genannten Release-Effekt. Das bedeutet, der Wirkstoff bleibt in der Faser gespeichert und wird kontinuierlich über einen längeren Zeitraum nach außen abgegeben“, betont Wendler.

Bei der Verwendung in Atemschutzmasken kommt der Faser noch ein besonderes Merkmal zugute: Lyocell absorbiert Feuchtigkeit sehr gut. Damit wird ein großer Nachteil von Schutzmasken abgeschwächt: Die Ausatemluft durchfeuchtet das Filtermaterial mit der Zeit und macht es so zu einem idealen Nährboden für das Überleben und die Vermehrung von Keimen. Nicht so mit der Entwicklung aus Rudolstadt. Dank der natürlichen Eigenschaften der Lyocell-Faser kann das Vlies bis zu 50 Prozent seines Materialgewichts an Feuchtigkeit aufnehmen. Und die in der Faser gebundenen Silber-Ionen machen die Bakterien rasch unschädlich. Daher können solche Atemschutzmasken vergleichsweise länger getragen und mehrfach verwendet werden.

Die Nachfrage nach Cell Solution bioactive steigt gerade stark an: smartpolymer konnte die Produktion vom großen Labormaßstab erfolgreich auf den Technikumsmaßstab übertragen. Mit Einführung eines Drei-Schicht-Systems soll das Volumen nun kurzfristig so weit wachsen, dass bis zu 10 Tonnen Textil pro Monat mit der Faser ausgerüstet werden können. An einem weiteren Scale-up wird bereits mit Hochdruck gearbeitet.

Die Faser Cell Solution bioactive ist bei der Prüfgemeinschaft Oeko-Tex gelistet und für den Einsatz in Textilien zugelassen. „Zudem erfüllt sie im Stoffkreislauf alle Anforderungen der Nachhaltigkeit“, ergänzt Wendler. „Die Faser wird besonders umweltverträglich hergestellt und ist biologisch abbaubar.“
