From the Sector

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.”

• Diana, Giusy, Simona and Marina. The call to action of the fashion world was born from four women engaged in the field of sustainability. On the occasion of Fashion Revolution Week, we tell you their story and the results achieved

A task force of Italian textile companies active in our area supported the first call to action launched at the fashion world by four women who have always been involved in the field of sustainability. The appeal launched on March 19th by the green journalist Diana de Marsanich, Giusy Bettoni, founder and CEO of C.L.A.S.S. (Creativity Lifestyle and Sustainable Synergy)the eco multi-platform hub specialized in integrating a new generation of eco values into fashion, products and companies, Simona Roveda, Editorial Director and Director of Institutional Communication of LifeGate and Marina Spadafora, Italian Country Coordinator of Fashion Revolution and currently collaborating with Luxury Fashion Brands to implement responsible strategies in their companies have luaunched a call-to-action project which has brought together textile companies to manufacture PPE garments for the medical staff working in San Gerardo Hospital in Monza, near Milan.

The companies that answered the call-to-action are: Filo d’Oro, Mantero, ROICA™ by Asahi Kasei, C.L.A.S.S. (Creativity Lifestyle and Sustainable Synergy) e Zerobarracento, Iluna Group, Lg Electronics, Jimmy Lion, Personal Genomics, Isamar Holyday Village, Marcolin Eyewear, Maglificio Ripa.

During the last weeks the 4 women collected about 1,800 non-drip cotton and non-woven TNT gowns for sanitary use, about 400 protective masks for multipurpose washable, bacteriostatic, breathable and water-repellent prevention, 1,000 washable cotton surgical caps, 150 complete protective googles eye masks, two microwave ovens for hospital departments to offer support to medical and healthcare personnel by helping them in the few breaks during the grueling shifts of this period, a supply of samples of cotton socks, 300 cotton masks + polyester outer layer, water-repellent and antibacterial, and free weekly stays made available to doctors, nurses, civil protection personnel and families with related children involved in the Covid-19 pandemic.

In mid-March, CHT Germany GmbH, which specializes in specialty chemicals, took up production and distribution of hand disinfectant. Now the company is expanding its product portfolio by adding important medical supplies that can help fight Covid-19 (SARS-CoV-2). Starting immediately, CHT is providing its business customers with surface disinfectant, textile supplies for medical protective wear as well as supplies for test kits and face masks.

Following increased demand for disinfectant in the wake of the new coronavirus, the CHT Group began already a month and a half ago to produce hand disinfectant at its factory in Dußlingen. Since then, more of its factories around the world had joined in. Now the CHT Group is complementing this offering by producing its own surface disinfectant based on ethanol. As with the hand disinfectant, the production of the surface disinfectant received a special approval, based on the expanded general ruling by the German Federal Agency  for Chemicals (BAuA). Both types of disinfectant use publicly available standard formulas for alcohol-based disinfectant from the World Health Organization (WHO). The sale of CHT’s surface disinfectant, which is available in 5-, 10- and 30-liter canisters, is exclusively for use by industry customers.

In addition, the CHT Group is manufacturing a range of textile-relevant products that provide protection from Covid-19. These include functional supplies for face masks for medical protective wear, as well as flocking for test kits. Through these offerings, the CHT Group also wants to support the textile sector, which has been strongly affected by the crisis.

Staggered in terms of timing and with varying magnitude, the global spread of coronavirus is impacting the development of the regional economies in the core markets of the Manmade Fibers segment of the Swiss Oerlikon Group.
The sales markets for manmade fiber systems and equipment have been primarily located in China, India and Turkey for many years now. Together, these markets – above all China – make up the lion’s share of the project landscape at Oerlikon Manmade Fibers. And this is paying positive dividends at the moment. Because the production facilities of the major manmade fiber manufacturers in
China have been systematically fired up again over the past few weeks, with capacity utilization increasing consistently.

Going against the flow
The Segment CEO, Georg Stausberg explains the reason: “Long before the coronavirus situation developed, the major manmade fiber manufacturers in China had decided to reverse-integrate their production chains to include petrochemicals in order to expand their portfolios with targeted investments, to reduce their dependence on a ,single product’, to optimize their costs and ultimately to acquire greater control over margins in a global volume business”.
Similar processes and decisions – albeit not on the same scale as in China – have also
been detected at the large manmade fiber manufacturers in India and Turkey. Even though businesses in India and Turkey are presently still temporarily severely impacted by the coronavirus situation, their long-term commitment cannot however be questioned, as the company-internally-agreed plans will be systematically implemented moving forward.

Long-term investments of global market players
All this has recently resulted in increased demand for spinning and texturing systems – just like those supplied by total solutions provider Oerlikon Manmade Fibers with its
Oerlikon Barmag, Oerlikon Neumag and Oerlikon Nonwoven product brands.
“The investments in petrochemical systems are based on long-term strategic considerations and are resulting – even during the coronavirus pandemic – neither in short- and medium-term economic dips, nor in changed customer behavior. (...)”, states Segment-CEO Georg Stausberg.
As a result of Oerlikon Manmade Fibers delving into the digital age years ago, the segment has experienced the intensive and short-term benefit from all the measures, in part also in its processing of customer projects.

• Antiviral properties of Sanitized® products on synthetics validated

Tests conducted by independent laboratories have now confirmed that a treatment with Sanitized® T 99-19 and Sanitized® T 11-15 reduces the viral load on PES textiles by
up to 99 %.

Swiss company SANITIZED AG announces the validation from impartial labs that Sanitized®T 99-19 and Sanitized®T 11-15 are also effective against viruses (in accordance with ISO 18184:2019). Tests were performed using a feline coronavirus with structures and mechanisms reminiscent of SARS-Cov2. Patented technology featuring an ammonium silicate compound  is employed in Sanitized®T 99-19 and Sanitized®T 11-15 utilizes tried and tested silver technology.

These additives are the perfect tool for an antiviral and antibacterial treatment of face masks, protective professional medical clothing, bed linens, or mattresses. The formulation of both products remains completely untouched, thus ensuring that it will continue to offer outstanding protection against bacteria.

Before a final product’s antiviral properties can be publicly promoted, viral tests must be performed in specialized laboratories. Compliance with local legal regulations is essential here. SANITIZED AG explicitly points out that this is standard procedure and has composed a preliminary Guide for Treating PPE (personal protective equipment) with biocide products.

Die aktuell geltenden behördlichen Vorschriften, die zur Eindämmung der Ausbreitung des neuen Coronavirus und zum Schutz der Gesundheit und des Wohlbefindens des Personals und der Kunden erlassen wurden, erfordern von Einzelhändlern die Einführung von Maßnahmen zur Wahrung von sozialer Distanz und von neuen Belegungsregeln.
Checkpoint Systems,  Anbieter von Source-to-Shopper-Lösungen, bringt mit „Smart Occupancy“ ein neues System auf den Markt, mit dem Einzelhändler die Kundenanzahl in ihren Läden in Echtzeit erfassen und darauf reagieren können.

Das System zählt die Anzahl der ein- und ausgehenden Personen und sendet eine Warnung an das Personal, wenn das Geschäft fast die maximale Kapazität erreicht hat. Filialleiter können Schwellenwerte festlegen und ändern, verschiedene Zonen mit unterschiedlichen Ein- und Ausgängen sowie Konzessions- oder Toilettenbereiche einrichten.
Dadurch können die Mitarbeitenden in Echtzeit auf die gegenwärtigen Belegungszahlen reagieren und so zu einer sichereren Umgebung für Angestellte und Kunden des Ladens beitragen.

Rot, gelb oder grau signalisiert die aktuelle Ladenbelegung
Mitarbeitende und Filialleiter können online oder über ein Tablet im Laden auf die Belegungsinformationen zugreifen. Visuelle Farbanzeigen auf dem Tablet ermöglichen dem Personal, auf einen Blick einen möglicherweise überschrittenen Schwellenwert zu erkennen: Rot zeigt an, dass das Geschäft seine Kapazität erreicht hat. Gelb bedeutet, dass die Belegung fast erreicht ist, bei grau sind keine Belegungswarnungen notwendig. Bei zu hoher Belegung wird eine zusätzliche Warnung an das Ladenpersonal gesendet, damit dieses angemessen reagieren kann.

SmartOccupancy verwendet Visiplus 3D, den genauesten Overhead-Personenzählsensor, der mit dem Cloud-basierten Softwareportal HALO von Checkpoint Systems verbunden ist. Dank dieser Verknüpfung können Einzelhändler auf Berichte über die Ladenbelegung in einer bestimmten Region zugreifen sowie die Belegung in den Läden überwachen, um den festgelegten Schwellenwert beizubehalten oder zu ändern.

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.“
