• BIONIC-FINISH®ECO Fluorine-Free, Water Repellent Finishes for Ultimate Performance

In recent years, many scientists have shifted from favoring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. Regardless what the real beginning really was, water was certainly involved in the process some 3,5bln years ago. And since then, Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by turning to those 3,5bln years of experience and by using natural design as springboard. That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Back in 2003, RUDOLF GROUP borrowed from Mother Nature the idea of dendrimers (from dendron, Greek word for ‘tree’), molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multicomponent systems. These hyper-branched polymers attach to the textile and embed fluorine-free, durable water-repellent performance.
In 2021 BIONIC-FINISH®ECO comes as a reviewed and extended family of unique nonhalogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs. Still very much based on patented dendrimer technology, the new and strengthened BIONIC-FINISH®ECO’s product portfolio:

• Provides non-fluorinated and highly durable water repellent textile finishes for high-performance, professional applications (e.g. when brushing resistance is required);
• Delivers highly efficient and durable performance with low application amounts thus not affecting fabric feel and appearance (e.g. when remarkable softness is important);
• Fulfills a range of challenging technical requirements (e.g. minimal impact on flame retardant properties of technical fibers);
• Is suitable for both sportswear and outdoor applications, as well as for casual apparel and fashion clothing;
• Is bluesign® approved, ZDHC chemical gateway certified and compliant with most RSLs;

BIONIC-FINISH®ECO new portfolio includes universal and versatile solutions targeting the most standard requirements, as well as customized solutions that meet more demanding and specific expectations such as improved resistance to dry-cleaning. “None of us can entirely predict where our voyage will lead” says Dr. Gunther Duschek, RUDOLF GROUP Managing Director. “However, BIONIC-FINISH®ECO of RUDOLF GROUP will always be the fluorine-free, durable water repellent for ultimate  performance. As it is today”.

Sächsische Mittelständler kämpfen mit Innovation und Know-how im Bereich der FFP2-Masken gegen minderwertige Qualität aus Asien.

„Den Mittelständlern wurden von der Bundesregierung viele Millionen für die Entwicklung von textiler Schutzausrüstung in der Pandemie versprochen. Doch angekommen ist bei den Textilern in Sachsen bis jetzt nichts“, stellt Dr.-Ing. Jenz Otto, Hauptgeschäftsführer des Verbandes der Nord-Ostdeutschen Textil- und Bekleidungsindustrie e.V. (vti), enttäuscht fest. Während die deutschen Bürger in den Apotheken nach wie vor Masken aus China mit teilweise fragwürdigen Kennzeichnungen auf die Gutscheine der Bundesregierung erhielten, würden für die Qualitätsmasken „made in Germany“ internationale Vertriebswege aufgebaut.

Sächsische Textilunternehmen aus dem vti-Verbandsgebiet, die den Aufrufen der Regierung zur Produktion von Schutzausrüstung im Frühjahr 2020 mit Euphorie, viel Enthusiasmus, hohen Investitions- und Entwicklungskosten gefolgt sind und den Versprechungen vertraut haben, seien bei der Förderung leer ausgegangen.

Das weltweit agierende Unternehmen Norafin Industries (Germany) GmbH (Norafin) führt die Tradition der Textil- und Vliesstoffindustrie fort.
Als die Corona-Pandemie im Frühjahr 2020 in Deutschland ankam, entstand ein neuer Produktionszweig bei Norafin.

Der Vliesstoffspezialist Norafin fand sich mit dem Anlagenbauer XENON Automatisierungstechnik GmbH aus Dresden zusammen. Beide Unternehmen entwickelten eine High-Tech-Maskenproduktionsanlage, die zertifizierte FFP2-Masken vollautomatisiert, ohne manuelle Arbeitsschritte produziert. Ab Juni waren 20.000 Alltagsmasken „Nora LIGHT“ pro Woche mit der ersten Pilot-Anlage möglich. Mittlerweile ist bereits der Nachfolgetyp mit einer Kapazität von 250.000 Masken pro Woche in Betrieb.

Die zertifizierte FFP2 Maske „Nora F“ filtert mindestens 94 Prozent der Partikel und Aerosole größer als 0,6 μm. Damit minimiert sie für den Träger und sein Gegenüber das Corona-Infektionsrisiko im geforderten Standard.Die Maske besteht aus vier Schichten Spezialvliesstoff. Die Außenlage (100 Prozent PET) sorgt für Stabilität und eine erste Filterung von Staub, die doppelte Mittellage (100 Prozent Polypropylen) sichert die Filtration der Aerosole ab und die Innenlage (ebenfalls 100 Prozent PET) transportiert die Feuchtigkeit der Atemluft nach außen.

Diese Masken können auch in der industriellen Anwendung in rauen Arbeitsumgebungen für den sicheren Arbeitsschutz im Umgang mit Glasfasern, Metall, diversen Kunststoffen und Ölnebel sorgen.

Die nächste Innovationsstufe der „Nora F“ ist mit drei Schwerpunkten bereits fest geplant. Dabei stehen die Nachhaltigkeit mit recyclingfähigen und kompostierbaren Materialien, die antivirale und bakterielle Funktionalität sowie der Tragekomfort im Blickpunkt des Entwicklungsteams um Marc Jolly, Head of R&D und Johannes Loos, Business Unit Manager bei Norafin.

André Lang, Geschäftsführer von Norafin, und sein Team sind hochmotiviert an die Entwicklung und Herstellung der Masken gegangen, haben viele Zusatzschichten mit den XENON-Ingenieuren für die Maske „made in Saxony“ aufgebracht und jeweils hohe sechsstellige Summen investiert. Umso enttäuschter war das Team als der Ablehnungsbescheid für die Förderung der sächsischen Maskenproduktion vom Bundeswirtschaftsministerium einen Tag vor Weihnachten ankam.
Norafin geht daher jetzt auch eigene internationale Vertriebswege.

Dr.-Ing. Jenz Otto vom vti plant für die Unterstützung der Vertriebsaktivitäten der Unternehmen aus dem Verband auch in diesem Jahr wieder eine Präsentationsveranstaltung mit Anwendern textiler Gesundheits- und Schutzausrüstung am 28. September 2021 in Chemnitz.

Hexcel announces its latest HexPly® XF surface technology that reduces shell manufacturing time within the wind blade surface finishing process. HexPly XF increases overall blade manufacturing efficiency by reducing time in the mold by up to two hours and by banishing surface defects that require rework before painting.

Hexcel’s HexPly XF surface technology has been formulated to address the limitations of current blade shell surfacing techniques whereby pinholes and other surface defects have to be repaired by hand to achieve the perfectly smooth surface required for painting.

HexPly XF surface technology introduces a new material format as the surface finishing layer, eliminating the need for a traditional in-mold gel coating process. HexPly® XF for infused rotor blades, is a lightweight non-woven semi-preg construction, comprising an epoxy resin matrix, that co-cures with standard epoxy infusion systems. The product has a successful track record in prepreg blades and has now been adapted for infusion processes.

Easy to handle and supplied in a ready to use roll form, HexPly XF can be quickly applied by hand or with semi-automated layup equipment. It features one self-adhesive, surface finishing side - indicated by a removable protective foil. This side of the prepreg is placed against a release agent treated mold surface. Once the material has been positioned, the lay-up of the blade shell structure can start immediately, and the laminate can be infused. After curing, the blade is de-molded with the manufacturer benefitting from a pinhole-free surface that needs minimal preparation before painting.

HexPly XF material is less than half the weight of a typical gel coat per square meter, reducing the overall weight of the blade. Additionally, the consistent areal weight and thickness of the prepreg film provide a completely uniform surface coating, ensuring blade weight distribution and balance are maintained, which is critical as rotor diameters continue to increase. With no need to handle or mix liquid chemicals as in the gel coat process, HexPly® XF also improves the health and safety working conditions on the shop floor.

The material has a shelf life of six weeks at ambient temperature, which also minimizes cold storage requirements and helps to reduce scrap.

Order Intake Continued to Recover in the Fourth Quarter of 2020:

• Order intake increased to CHF 215.1 million in the fourth quarter of 2020 and reached a total of CHF 640.2 million in the 2020 financial year
• As expected, sales of CHF 573.0 million in the 2020 financial year were significantly down on the previous year
• EBIT margin of around -15% and net profit of around -16% of sales expected
• First half of 2021 still heavily impacted by the COVID-19 pandemic
• Change to the Group Executive Committee

Rieter posted a globally and broadly supported order intake of CHF 215.1 million in the fourth quarter of 2020. Thus, the recovery that began in the third quarter of 2020 after the slump in demand in the second quarter continued (order intake second quarter: CHF 45.7 million, third quarter: CHF 174.4 million). Overall, Rieter’s annual order intake for the 2020 financial year totaled CHF 640.2 million, which corresponds to a decrease of 31% compared to the previous year.

At the end of 2020, the company had an order backlog of about CHF 560 million (December 31, 2019: about CHF 500 million).

As expected, as a consequence of the economic effects of the COVID-19 pandemic, the Rieter Group closed the 2020 financial year with considerably lower sales than in the previous year. According to the first, as yet unaudited figures, total sales of CHF 573.0 million were achieved, which corresponds to a decrease of 25% compared to the previous year (2019: CHF 760.0 million).

Order Intake by Business Group
All three business groups were affected by the slump in demand in the second quarter of 2020 due to the COVID-19 pandemic. Despite the recovery in order intake in the third and fourth quarters of 2020, the weak second quarter was only partially offset.

The Business Group Machines & Systems was particularly hard hit by the effects of the pandemic, with a year-on-year decline of 35%. The Business Groups Components and After Sales each recorded a 24% reduction in order intake.*

Sales by Business Group
The exceptional market situation in 2020 gave rise to a significant decline in sales in all three business groups. Accordingly, reluctance to invest and deferred deliveries by customers caused sales in the Business Group Machines & Systems to decline by 24% compared to the previous year.

Due to COVID-19, a large number of spinning mills stopped production worldwide. This led to low demand for spare parts and wear parts, especially in the second and third quarters of 2020. Accordingly, compared to the previous year, sales in the Business Groups Components and After Sales fell by 24% and 27% respectively in the 2020 financial year.*

Sales by Region
With the exception of Turkey, all regions were affected by the low demand as a consequence of the COVID-19 pandemic.*

EBIT Margin and Net Profit
In the 2020 financial year, Rieter anticipates an EBIT margin of around -15% (2019: 11.2%) and net profit of around -16% of sales (2019: 6.9%). As of December 31, 2020, Rieter had liquid funds of exceeding CHF 280 million and unused credit lines in the mid three-digit million range.

First Half of 2021 Still Heavily Impacted by the COVID-19 Pandemic
Thanks to the improved capacity utilization, Rieter is planning short-time working in only a few areas in the first half of 2021. Nevertheless, Rieter expects sales in the first half of 2021 to be below the break-even point.*

Change to the Group Executive Committee
With effect from March 1, 2021, the Board of Directors of Rieter Holding Ltd. has appointed Roger Albrecht as Head of the Business Group Machines & Systems and a member of the Group Executive Committee.*

Annual General Meeting April 15, 2021
The 2021 Annual General Meeting of Rieter Holding Ltd. will take place in Winterthur on April 15, 2021.*

From the drinking water and food industries through water management and mining to the automotive and aviation sectors, mechanical filtration processes are used in almost every industry. As different as the methods, dimensions and special requirements of the filtration process are in each case – technical textiles and often tubular filters are almost always used. This means that tubular filters and narrow textiles by vombaur contribute to the safe and reliable separation or treatment of substances in the widest variety of filtration processes.

Individual solutions
The requirements placed on the textile, the material, the flow rate and the loading capacity of the filters depend on the respective use: a tubular for dewatering soil needs to withstand different forces than a tubular filter for the beverages industry. On the other hand, the latter needs to meet the highest hygiene standards. Because the requirements are so individual, vombaur develops customised filtration textiles for its customers all over the world.

Seamless tubular filters
At vombaur, filter media are round woven seamlessly on unique looms. As a result, they have identical surface properties all around and over the entire length, such as flow rate, loading capacity, shrinkage behaviour or material thickness

Narrow textiles for fabricating filter media
"We manufacture our narrow textiles from a wide variety of high-tech yarns. Sometimes monofilament yarn is used, sometimes multifilament, sometimes spun yarn. Like the type of weave, we select the raw materials depending on the function they need to fulfil," emphasises Gert Laarakker, Sales Manager at vombaur. "So that our filtration textiles reliably perform the job they are supposed to perform. Clean. Safe. Sturdy."

Sorpol Ltd., a leading importer and distributor of industrial raw materials in Israel, has launched a website to sell Acteev Protect™ masks, made in the USA by polyamide manufacturer Ascend Performance Materials. The two companies also plan to partner in the distribution of Acteev surgical masks, N95 respirators, nonwoven media and textile fabrics as they become available.

Laboratory tests have demonstrated Acteev fabric effective at deactivating 99.9% of the viruses SARS-CoV-2, the cause of COVID-19, and H1N1, a flu virus. Acteev technology also eliminates bacteria and fungi.

Ofer Soreq, Sorpol’s marketing director, said the Acteev Protect line fits in neatly with the mission of the company.

Recent testing on Acteev fabric completed at the University of Cambridge has demonstrated that Acteev technology deactivates the virus that causes COVID-19, SARS-CoV-2, with 99.9% efficacy on contact. Ascend has submitted several masks designs to the U.S. Environmental Protection Agency and the U.S. Food and Drug Administration to obtain the appropriate regulatory clearances to make specific claims regarding the technology’s antiviral properties in the United States.

In addition to antiviral, antifungal and antibacterial protection, the washable, reusable masks are lightweight, breathable and odor-fighting, making them comfortable to wear during a long shift at work or for outdoor workouts.

Acteev Protect shows promise for use beyond masks, according to Ascend. The technology was originally developed for workout wear, and now the company is working on textile applications ranging from gloves to scrubs to high-end athleisure

• World Congress on Textile Coating, to take place on 11-12 & 18-19 February 2021.

The conference organisers have developed a well-structured programme of five sessions over four days with live discussion forums following each session for maximum attendee participation.

“The programme aims to be inspiring and informative, and will showcase the best innovations and collaborative actions in the industry. Functionality can be added to textiles and nonwovens at the beginning or the end of the supply chain, with an increasing range of raw materials, offering many options when designing and realizing a high-performance fabric. At the other end, there are many ways, such as applying a coating, to add functionality to an otherwise finished product. For example, the current pandemic has prompted new commercial anti-viral processes and four such presentations will outline the impact on industry and its response to the global pandemic,” says Dr Nick Butler, head of the conference organising committee.

World Congress on Textile Coating will feature time dedicated to networking, encouraging attendees to interact with conference speakers and industry peers throughout the online programme, offering the opportunity to expand professional networks. All the presentations and discussion forums will be recorded for post-event viewing. Event sponsors imogo AB, Lamberti SpA, JX Nippon ANCI and Weitmann & Konrad GmbH & Co. KG will give individual presentations and host Q&A during the four days of the event.

First edition of JEC Summit Sports & Health – Connect, an online event platform devoted to medical and sports equipment manufacturers using composites, ended last week going above and beyond its set goals. JEC Summit Sports & Health – Connect brought together professionals from the whole composites value chain and allows decision-makers to evolve and inspire through a subsequent event program. This summit was the first in a long line of events devoted to composites in the Sports and Health industry that are to come within the next two years.

The three-day event was conceived as a forum to gather composites professionals, affiliates, and high-profile speakers to share their expertise in composites materials involved in creating state-of-the-art medical devices and sports equipment.

“Following the enforced postponement of many trade shows, we took the step of becoming the first organizer to stage an online event dedicated to composites in the sports and health industry. We put together a high-level conference agenda and speaker roster, and devised some great ideas for virtual networking, said Christian Strassburger, Event Director at JEC Group. “I could not be prouder of what we achieved with many delegates from Europe and Americas tuning in, including representatives from more than 36 countries. I would also like to take this opportunity to thank all our sponsors and partners. Their trust, support, and input were a crucial part of both the quality and success of the summit.”

The event attracted an audience of more than 1,100 professionals from the composites industry, from 36 countries, and helped organize 216 pre-arranged one to one meetings between buyers and sellers via our dedicated online meeting rooms, this without mentioning informal networking between participants. It reached these numbers, as participants logged on in considerable numbers to learn from the insights and ideas of the unparalleled line-up of high-level speakers who took part in the summit’s twenty-track conference.

The agenda for the JEC Summit Sports & Health – Connect featured tracks on current trends and Innovations in sports & health composite applications, with keynotes delivered by Dominic LeBlanc Senior Concept Engineer, at Callaway Golf, Christophe Lecomte, Director of Biomechanical Solutions R&D, at Össur, Fleur Jong, Professional Sprinter, and Co-founder of the Para Athletics Foundation and Damiano Salvatori, Materials Research Engineer, at the Straumann Group.

The panel of high-profile experts from Europe and America offered perspectives and inspiration for the next generation of medical and sports devices made of composites materials. The line-up included Bjorn Ivar Austrem, Technical Director, at Madshus, Laurine Calistri, Research Engineer, at Proteor, Anatole Gilliot, CEO of Suprem, Julien Duplay, Composites Methods Engineer, at Decathlon, Eric Jackson, President of Apex Watercraft, Stéphan Vérin, General Secretary, at EuraMaterials, Maximilian Segl, Principal Expert Composites, and Johannes Wölper, Development Engineer, both from Ottobock, and Matthew Dickinson, Senior Lecturer in Engineering, at University of Central Lancashire. Christos Karatzias, at Mitsui Chemicals Europe and Anthony Bert, at Helicoid Industries.

And one cannot omit the international startups that pitched all through the three-day event: ProsFit (Bulgaria), Alchemy (Greece), moi composites (Italy), Mercuris (Germany), Arevo/Superstrata (USA), Checkerspot/WNDR Alpine (USA), Ambrocio (Finland) Nairoby (Argentina). All gave inspiring and promising perspectives in the sector and what to look for in the near future.

• Leading Turkish textile printing company Hamle has installed a new Monforts Thermex dyeing range as part of its ongoing strategy of continuous investment.

“Investment in new technology and capacity expansions are very important to us, in order to stay ahead in terms of sustainable, high quality production,” says general manager Gürkan Uzuner. “We carefully assess the benefits of each advanced new technology in order to thrive in a sector that is constantly changing.

“The Zara Group is a major European customer for us, along with well-known Turkish brands such as LCW and De-Facto, and it’s no accident that Çorlu, due to its proximity to Istanbul and the ease of supplying to Europe, has become the epicentre of Turkish textile production. The quality of textiles coming from the region is now very well proven.”

Integration

Hamle’s plant in Çorlu already houses a Monforts ten-chamber Montex stenter and two Monforts sanforizing ranges on which the company carries out an extensive range of finishing processes. The new Thermex range further integrates a number of processes on technology all from a single supplier. The Thermex universal hotflue for continuous dyeing, condensing and thermosoling achieves unrivalled reliability even at maximum fabric speeds, for exceptional cost-effectiveness when dyeing both large and small batches of woven fabrics. The new range installed for Hamle benefits from the Econtrol® process* for reactive dyestuffs. This is quick and economical one-pass pad-dry and wash off process, with drying in the hot flue at 120-130°C and controlled humidity (25-30% by volume) to obtain fixation in 2-3 minutes.
Econtrol® ensures excellent reproducibility of all colours, improved dye penetration on difficult fabrics and no risk of the browning of cotton or other cellulose fibres due to the low fixation temperature.

As such, it is the ideal process for fast change technology and operational savings. “The new Thermex range has some very advanced automation features which ensure our machine operators have full control over the entire system,” Mr Uzuner concludes. “ As the Monforts representative in Turkey, Neotek has been our solution partner in the installation and commissioning and has been with us every step of the way.

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."
