From the Sector

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, received the prestigious Technical Innovation Award from the Flexographic Technical Association (FTA) for its recently introduced SteadyPrint print-stabilization technology. This award was presented May 5, 2019, at the FTA Forum 2019 awards banquet held in New Orleans.

SteadyPrint, now part of PCMC’s Fusion and ELS Max flexographic presses, couples innovative patented mechanical designs with cutting-edge disturbance-cancelling algorithms that suppress disturbances associated with the hard edge, largely removing the impact of bounce in flexographic printing. The press automatically learns when the disturbance occurs on each job and implements the cancellation algorithm to minimize or eliminate the impact on print quality.

“We are extremely excited to be a recipient of the 2019 FTA Technical Innovation Award,” said Rodney Pennings, PCMC’s Printing, Coating and Laminating Sales Director. “The entire PCMC team has worked very hard in developing SteadyPrint over the past couple of years. It is an innovation that we are quite proud of, and we appreciate the accolades that showcase SteadyPrint within the package-printing industry. Winning this award in the year we are celebrating our 100-year anniversary is also incredibly meaningful.”

A wide range of new technologies will be demonstrated by Vandewiele at the ITMA 2019 textile machinery show in Barcelona from June 20-26, including the latest RCE2+ digital carpet weaving machine.

All Vandewiele technologies are now being equipped for machine-to-machine interaction and learning, as part of the company’s comprehensive TEXconnect programme.

Meeting new industry needs
As a leader in complete carpet manufacturing systems – including BCF extrusion lines, heat setting systems and carpet weaving and tufting machines – Vandewiele has rapidly responded to the evolving needs of the textile industry for smaller and customised production runs, the most challenging of designs, and faster and more sustainable manufacturing.

The company’s sensors, software programmes and servers have become increasingly sophisticated as part of the TEXconnect program, and the real-time data from different machines – across connected manufacturing sites and across different countries and even continents – can be collected and shared. Digital models of both machines and production processes can be created and analysed for the optimisation of production settings, to vastly improve scheduling and planning and also make considerable savings in raw materials and energy consumption.

Virtual and remote control now allows for the Big Data analysis that is propelling the industry forward and will pave the way for AI applications. For carpet manufacturers, all of this is leading to the creation of truly Smart Factories.

RCE2 carpet weaving
The new RCE2+ Rug and Carpet Expert weaving machine is a truly digital workhorse, with all yarns continuously controlled and measured and the difficult bobbin changes of the past completely eliminated. This is as a result of Vandewiele’s latest Fast Creel, with the feed and tension of each pile yarn controlled by individual servomotors.

The pile yarns are now fed directly into the machine without having to pass pile-stop motions, to both increase efficiency and eliminate any waste yarns, while achieving previously unreachable industrial speeds.

The filling enters the machine smoothly via the latest IRO X3 winders, heavy duty filling brakes with multi lamellas, an active yarn recuperator and a high speed weft mixer, where again, all tensions are set electronically. Vandewiele’s servo-driven heddle frames (Smart Frames) are meanwhile already well proven in the industry.

TEXconnect further provides readily-available data on all yarn consumption, tension and threading, and then will supply the predictive maintenance that is paving the way to self-learning carpet weaving machines.

All of this would be unnecessary, if it didn’t result in allowing manufacturers to make the highest quality carpets at the most economic prices ever, with savings on the highest-bulk pile yarns from the Vandewiele extrusion lines, reduced waste yarns in the creel and industrial production speeds that have never before been attained.

• Hexcel’s Composite Innovations For Aerospace, Automotive, Energy And Marine Applications At JEC World 2019 Hall 5 - Stand J41

STAMFORD, Conn. – At this year’s JEC World taking place in Paris on March 12-14, Hexcel will promote a wide range of composite innovations for customer applications in aerospace, automotive, energy and marine markets.

Aerospace Innovations

Hexcel’s HiTape® and HiMax™ dry carbon reinforcements were developed to complement a new generation of HiFlow™ resin systems, producing high quality aerospace structures using the resin infusion process. HiTape® was developed for the automated lay-up of preforms and HiMax™ is a range of optimized non-crimp fabrics (NCF). Both products incorporate a toughening veil to enhance mechanical properties, meeting the structural requirements for aerospace parts.

Visitors to JEC will see an Integrated Wing Panel demonstrator and an I-beam, both made with HiTape® reinforcements, and an Opticoms rib made with HiMax™ NCF. The Opticoms rib and I Beam were both manufactured using C-RTM (Compression Resin Transfer Molding). They were injected with Hexcel’s RTM6 resin in a process taking less than 5 minutes. The total manufacturing cycle for both parts was just 4.5 hours.

Also among the Aerospace exhibits, Hexcel will display a composite petal for a satellite antenna, manufactured by Thales Alenia Space Italia. The petal is part of a set of 24 deployable structural elements that form the large area reflector assembly used on board Low Earth Orbit (LEO) observation satellites. Thales Alenia Space Italia selected Hexcel’s HexPly® M18 prepreg for this application, acknowledging the superior mechanical and outgassing properties provided.

Another Hexcel prepreg application on show is a “zero” frame, manufactured by Aerofonctions for the engine area of Daher’s TBM 910/930 single-engine turboprop aircraft. Hexcel’s HexPly® M56 prepreg was selected by Daher for the “zero” frame – a product developed for Out of Autoclave applications that provides the same high quality and performance as autoclave-cured prepregs, from a simple vacuum bag cure in an oven.

With 50 years of experience behind its comprehensive range of high-strength, high-strain PAN-based carbon fibers, Hexcel continues to innovate, and is introducing two new fibers to its portfolio. HexTow® HM50 combines high modulus and high tensile strength, making it ideal for commercial and defense aircraft and engines. HexTow® 85 was developed specifically to replace rayon-based carbon fiber for ablative applications.

HexTow® carbon fiber holds the most qualified carbon fiber positions on aerospace programs in the industry and is the best unsized fiber available on the market. It provides excellent bonding interfacial properties with thermoplastic matrices and is the best-performing fiber for 3D printing applications.

Additive manufacturing is another area of expertise for Hexcel, using PEKK ultra-high performance polymers and HexAM™ technology to manufacture carbon-reinforced 3D printed parts. This
innovative process provides a weight-saving solution for intricate parts in highly demanding aerospace, satellite and defense applications. HexPEKK™ structures offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts with a new technology.

Hexcel is well known for its range of weight-saving, stiffness-enhancing honeycombs and the company adds value by providing a range of engineered core solutions to customers from facilities in the USA, Belgium and the newly opened Casablanca plant in Morocco. Hexcel’s engineered core capabilities enable highly contoured parts with precision profiling to be produced to exacting customer specifications. An example of such a part will be on display at JEC. Made from Aluminum FlexCore®, the part is CNC machined on both sides, and formed and stabilized with both peel ply and flyaway layers of stabilization. Aircraft engines benefit from a number of Hexcel core technologies including HexShield™ honeycomb that provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with unique heat-shielding capabilities that allows for the potential re-use of material after a fire event.

Hexcel’s Acousti-Cap® broadband noise-reducing honeycomb significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core, or can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees Of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.

HexBond™ – the new name in Adhesives

Hexcel’s range of high performance adhesives has expanded considerably following the company’s acquisition of Structil. The company has now decided to unite the range by marketing all of its adhesive products using HexBond™ branding. The comprehensive range of HexBond™ structural film adhesives, foaming adhesive films, paste adhesives, liquid shims, epoxy fillets and Chromium free liquid primers is suitable for a wide range of applications in combination with Hexcel’s prepreg and honeycomb products.

Automotive Innovations

Hexcel’s carbon prepreg patch technology provides an innovative way of locally stiffening and reinforcing metal parts, providing noise and vibration management functionality. HexPly® prepreg patches consist of unidirectional carbon fiber impregnated with a fast curing epoxy matrix that has self-adhesive properties, enabling it to bond to metal in a highly efficient one-step process. These key technology properties are demonstrated in an 18.5kg aluminum subframe (that is 50% lighter than steel equivalents), which was reinforced with 500 grams of HexPly® prepreg and tested by Saint Jean Industries. The part demonstrates a significant reduction in noise, vibration and harshness (NVH). Other benefits include lower production costs, energy savings, increased driver comfort, production flexibility and part count reduction. With this technology Hexcel is a finalist in the JEC Innovation Awards 2019 in the Automotive Applications category.

HexPly® prepreg patch technology was also applied to a hybrid side sill demonstrator developed with Volkswagen and Dresden University to address future crash test requirements, specifically for electric cars. Combining fiber-reinforced plastic (FRP) with metal, the hybrid construction allows for optimum performance including weight savings, enhanced safety, increased energy absorption, battery protection in a crash situation and production flexibility.

Hexcel will also display a lightweight CFRP transmission crossmember produced from Hexcel’s high performance HexMC®-i 2000 molding compound. The transmission crossmember was developed in partnership with the Institute of Polymer Product Engineering (at Linz University), Engel and Alpex. As the part connects the chassis together and supports transmission it has to be stiff and strong, resisting fatigue and corrosion. Hexcel’s HexMC®-i 2000 was selected as the best-performing molding compound on the market, curing in as little as two minutes to produce lightweight, strong and stiff parts.
To produce the transmission crossmember HexMC®-i 2000 preforms are laid up in Alpex molds and compression-molded in a v-duo press that was tailored for the application by Engel. Ribs, aluminum inserts and other functions can be molded into the part using the single-stage process, reducing component-count. Any offcuts from the preforms can be interleaved between the plies of material to provide additional reinforcement in key areas - meaning that the process generates no waste.

Other Automotive promotions on Hexcel’s stand at JEC World include a composite leaf spring manufactured by ZF using HexPly® M901 prepreg. In contrast to steel leaf springs, composite versions offer many advantages including weight savings of up to 70%, high corrosion resistance, optimized system integration and superior performance. HexPly® M901 prepreg reduces the cure cycle to below 15 minutes and provides 15% higher mechanical performance, with enhanced fatigue properties. It also operates at high temperatures, providing a Tg of up to 200°C following a post cure.

Marine Innovations

Hexcel has a comprehensive range of products aimed at racing yacht and luxury boat builders that include America’s Cup, IMOCA class and DNV GL-approved prepregs, woven reinforcements and multiaxial fabrics for hull and deck structures, masts and appendages.

At JEC World Hexcel will display an IMOCA yacht mast manufactured by Lorima using HexPly® high modulus and high strength carbon fiber prepreg from Hexcel Vert-Le-Petit. Lorima is the exclusive official supplier of masts for IMOCA 60 class racing boats.

Hexcel’s HexTow® IM8 carbon fiber has been selected as the highest performing industrial carbon fiber on the market and will be used by spar and rigging manufacturer Future Fibres to manufacture their AEROrazr solid carbon rigging for all the teams in the 36th America’s Cup.

Hexcel’s HiMax™ DPA (Dot Pattern Adhesive) reinforcements are non-crimp fabrics supplied pre-tacked, allowing multiple fabrics to be laid-up more easily in preparation for resin infusion. Providing an optimal, consistent level of adhesion, they allow a faster and more consistent resin flow, as well as eliminating the use of spray adhesive for a healthier working environment and lower risk of contamination. Simply unrolled and applied to the mold or core layer before the introduction of resin, HiMax™ DPA fabrics are widely used in boat building, where lay-up times can be reduced by up to 50%.

Wind Energy Innovations

Hexcel has developed a range of HexPly® surface finishing prepregs and semi-pregs for wind turbine blades and marine applications. Providing a tough, durable and ready-to-paint surface without using in-mold coats, these products shorten the manufacturing cycle and reduce material costs. HexPly® XF2(P) prepreg is optimized for wind blades and has a ready-to-paint surface, straight from the mold, saving at least 2 hours of takt time.

Polyspeed® pultruded carbon laminates were developed for load-carrying elements in a blade structure and are manufactured with a polyurethane matrix that provides outstanding mechanical performance in terms of stiffness and durability. The blade manufacturing process is optimized, with increased throughput. The pultruded laminates are supplied in coils as continuous cross section profiles.
HiMax™ non-crimp fabrics using E-glass, high modulus glass and carbon fibers are also available in a wide range of unidirectional, biaxial and triaxial constructions. HiMax™ fabrics have applications throughout the turbine, from the stitched carbon fiber UDs used in the main structural elements, to glass fabrics and hybrids for blade shells and nacelles. There are also specialist applications such as lightweight fabrics for heated leading edge de-icing zones.

• Company to showcase innovation while marking its 100th anniversary

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, will showcase its extensive nonwovens converting experience at IDEA19, held March 25 to 28, 2019, in Miami. Attendees may visit booth #1660 to learn how PCMC’s modular equipment serves a variety of market needs, as well as join the festivities when the company commemorates its 100th anniversary with a cake celebration from 2 to 5 p.m. on Wednesday, March 27.

With the compact footprint of the Marlin Pro, crossfold wipe customers can save space, while also reducing waste and achieving the lowest cost per wipe.

New products for photopolymer and laser sinter printing methods from BASF 3D Printing Solutions GmbH (B3DPS) are on show from November 13 to 16 at Stand F20 in Hall 3.1 at this year’s formnext fair in Frankfurt. The BASF subsidiary is also announcing several new partnerships for the development and distribution of groundbreaking 3D printing solutions and products.

B3DPS has entered into a strategic partnership with the US company Origin, San Francisco, California for the further development of photopolymer printing processes. “Within the framework of an open business model, we are combining BASF’s material know-how with Origin’s expertise in printer software programming and the manufacture of the corresponding hardware,” explained Volker Hammes, Managing Director BASF 3D Printing Solutions GmbH. The collaboration has already shown the first signs of success. Origin has developed a new printing method where BASF’s new Ultracur3D photopolymers can be processed particularly well. The technology offers an optimal combination of a good surface finish and high mechanical stability, while also allowing for high material throughput.

B3DPS is working together with Photocentric, a manufacturer of 3D printers and their corresponding software and materials, on the development of new photopolymers and large-format photopolymer printers for mass production of functional components. Based in Peterborough, UK and Phoenix, USA, Photocentric has developed and optimized the use of LCD screens as image generators for its own printing systems. The two partners plan to offer the industry 3D printing solutions that replace parts of traditional manufacturing processes such as injection molding for small series, as well as enabling the production of large components.

The objective of the cooperation with Xunshi Technology, a Chinese printer manufacturer headquartered in Shaoxing, and operates in USA under the name Sprintray, will be opening new fields of application in 3D printing for the Ultracur3D product range of B3DPS.

Ultracur3D specialties for photopolymer printing processes
B3DPS has grouped well-established and new photopolymers designed for the respective 3D printing processes under the brand name Ultracur3D. BASF has developed unique raw materials for its new products that enable special part properties.
“Our Ultracur3D portfolio enables us to offer customers various UV-curable materials for 3D printing that provide far better mechanical properties and higher long-term stability than most available materials,” explained András Marton, Senior Business Development Manager at B3DPS. He added: “These materials have been developed for functional components that are subject to high stress.”

Expansion of distribution network for filaments
Innofil3D, a subsidiary of B3DPS, is entering into a partnership with Jet-Mate Technology, based in Tjanjin, China, for the distribution of plastic filaments in China. In parallel, a distribution agreement has been concluded with M. Holland in Northbrook, USA for the distribution of filaments in USA. “Since the USA is the largest market for filaments, we intend to strengthen our activities there,” said Jeroen Wiggers, Business Director 3DP Solutions for Additive Extrusion at B3DPS, adding: “Asia is another important market for us. We will be developing further distribution channels there and putting our Ultrafuse filaments on the Asian market in 2019.”

BASF’s portfolio of filaments for 3D printing are comprised of two categories; the well-established Innofil3D filaments based on generic polymers for conventional applications and polymer-based Ultrafuse filaments for advanced formulations used in demanding technical applications. One of the broadest filament selections on the market, this portfolio covers customer requirements ranging from prototype to industrial-scale production.

SLS: new 3D printing material with fire protection classification
New flame-resistant Ultrasint Polyamide PA6 Black FR meets UL94 V2 fire protection standards and is a new material class for use in selective laser sintering (SLS) processes, distinguished by high stiffness and thermal stability. In cooperation with one of the global leaders of public transportation vehicles, B3DPS has developed new components that meet vehicle fire protection requirements. “Together with our partner, we are currently producing prototypes, spare parts, and small series components, and are working to further improve flame resistance to meet additional certification specifications,” explained Hammes.
BASF introduced Ultrasint Grey PA6 LM X085 at AMUG this spring and now is followed by another product on show at formnext. Ultrasint PA6 Black LM X085 is based on polyamide 6, and can be processed at 175-185 degrees Celsius therefore making it suitable for most current SLS machines.

B3DPS adds polypropylene to its 3D printing portfolio
Through the acquisition of Advanc3D Materials GmbH in July 2018, B3DPS has expanded its range with numerous materials for use on laser sinter machines, including polyamide Adsint PA12, Adsint PA11, Adsint PA11CF and Adsint TPU flex 90.
Ultrasint PP is a special highlight. This polypropylene-based product exhibits outstanding mechanical properties and is frequently used in standard industrial production as it offers a good balance between price and performance. Ultrasint PP is distinguished by excellent plasticity, low moisture uptake, and resistance to liquids and gases. Prototypes and small batches can now be produced from the same material as used for traditional serial production. Post treatments such as thermoforming, sealing, and dyeing can be performed after printing.

At the Composites Europe in Stuttgart /06 - 08 November 2018), the Institut für Textiltechnik of RWTH Aachen University, short ITA, will be showing products, components and machines along the fibre composite process chain. The ITA will present itself at the booth of the Aachen Center for Integrative Lightweight Construction (AZL) in hall 9, booth E70. Various demonstrators will be used to present selected innovative processes and products over the individual steps. The exhibits come from different fields of application: From mobility applications to the construction sector. Here is an example from the field of "construction composites":

With the concrete bar stool with hybrid carbon reinforcement, the ITA demonstrates that textiles as reinforcement structures for concrete elements allow a enormous geometrical freedom of Design. So far, manual positioning of the textile reinforcement used to be time-consuming and complex, as permitted tolerances are in the millimetre range. Thus the production mainly contributed to the high costs of textile concrete.

At the ITA, the two industrial partners Albani Group GmbH & Co. KG and DuraPact 2.0 Kompetenzzentrum Faserbeton GmbH developed a new hybrid reinforcement with integrated spacer. This hybrid reinforcement reduces the time required to position the reinforcement by up to 60 percent and thus makes the material significantly more

The new, cost-effective hybrid reinforcement contains an integrated spacer and thus faciliates the positioning of dry and coated reinforcements. The integrated spacer allows several layers of reinforcement to be stacked quickly, allowing the desired degree of reinforcement to be set. The hybrid reinforcement consists of a carbon or glass fibre grid joined with a permeable polyamide mat and will be available in roll form from industrial partners in the near future.

Because aircraft engine noise contributes to environmental noise around airports and populated cities, the aerospace industry has been working on new aircraft designs that will emit less noise so they can meet the ever-increasing requirements imposed on the industry to reduce noise pollution. Shielding and absorbing aircraft engine noise at the source represents one of the most effective ways to address this issue.

Hexcel, a global leader in advanced composite technology, has been at the forefront of acoustic technology development with its Acousti-Cap® broadband sound-reducing honeycomb, which enables engine designers to reduce the noise from takeoffs and landings yet without adding significant weight to the aircraft.
 
“Hexcel has continued investing in the evolution of Acousti-Cap® product technology to improve performance and reduce cost,” said Imad Atallah, Group Product Manager for Honeycomb at Hexcel. “Collaboration with industry leaders, including NASA and Boeing, has been key to that development,” he added.
 
The 2DOF (Two Degrees of Freedom) honeycomb core acoustic liner was introduced in 2008 and was subsequently adopted and installed on the Boeing 787 Dreamliner inlet, the Boeing 747-8 inlet and transcowl, and more recently on the Boeing 737 MAX inlet. This success enabled continued technology development and evolution in MDOF (Multi-Degrees of Freedom) where the acoustic septum is inserted in the honeycomb cell at different heights, as well as having two septums in honeycomb chambers. This type of technology allows for improved acoustic attenuation at a broader frequency range, as well as increased absorption.
 
“Hexcel’s Acousti-Cap® technology has shown great performance benefits over competing technologies from the beginning” said Clark Smith, Director of Technology -- Core Products at Hexcel. “We have continued to improve the technology through taking advantage of the single cell treatment concept, by adding capability that the industry was looking for,” he added.   
 
Hexcel’s latest Acousti-Cap® technology was recently tested in a joint NASA-Boeing flight test on a B737 MAX test platform, and the results beat expectations as reported by Aviation Week. Collaboration between Hexcel and NASA over several years on the development of MDOF technology led to the successful test results on this latest flight test.
 
The ability to attenuate a broader noise frequency range and increase acoustic absorption with the Hexcel liner has allowed an optimized design of the overall inlet that reduces drag and improves noise attenuation. Hexcel continues to invest in acoustic liner technology and is proud of the positive results of this NASA-Boeing flight test.

Cinte Techtextil China opens its doors next week, with around 480 exhibitors from 22 countries and regions preparing for another successful showcase of the world’s leading textile innovations. Leading international and domestic brands will feature in halls N1 – N3 at Shanghai New International Expo Centre from 4 – 6 September, making Cinte Techtextil the ideal place to make connections and gain insight into Chinese and Asian market trends.

The technical textile industry in the Asia region, and China in particular, has been growing steadily and is predicted to continue doing so. China’s total output of technical textiles and nonwoven products is estimated to account for 30% of global production by 2020, and double that of 2013. This high potential for growth, achieved through investments worth billions of dollars, has drawn attention from European exhibitors, who are set to travel to the region for Cinte Techtextil.

Belt and Road: a success story for Buildtech
Following higher regulations and quality standards that aim to exceed Western levels, demand is high in China for production machinery. What’s more, with the national nonwovens market displaying particularly fast growth, Cinte Techtextil has attracted some of the world’s leading nonwoven and weaving machinery brands.

The fair will showcase leading global exhibitors across 12 application areas. Two areas to watch out for include Buildtech and Mobiltech, which are both performing well in Asia and specifically in China. The Belt and Road initiative brings Buildtech a great deal of benefits through China’s enormous investments in global infrastructure. Adding to this, China’s automobile production has been increasing 3% year-on-year, with particularly high growth seen in new-energy vehicles, SUVs and commercial vehicles. China has become the world’s largest auto producer, and this has been boosting progress in the Mobiltech category.

Cinte Techtextil fringe programme a hub of industry insight
A comprehensive fringe programme will keep Cinte Techtextil fairgoers up to date with industry news, with standout events including the 7th China International Nonwovens Conference. Focusing on the global nonwovens industry, topic highlights include the latest innovations in China’s nonwovens industry, an insight into the North American nonwovens market, future trends in the global hygiene product market, and more. The conference will also discuss innovations and developments in filter materials and the wipe industry.

The first day of the fringe programme will see a panel discussion in hall N1, moderated by the Taiwan Technical Textiles Association (TTTA), with confirmed panellists including DuPont, IBENA Textilwerke and SGS-CSTC Standards Technical Services. The panel will focus on current trends, developments and standards in the protective textile industry.

Other fringe programme events will include seminars and product presentations led by industry leaders on the latest global technologies and market trends, and an Innovation Showcase Area in a variety of application categories. 

The global antimicrobial market is big business. Demand is strong due to increasing public awareness about contamination and infections, and by consumers’ desire for protective solutions. At Cinte Techtexil China 2018, taking place Sept. 4-6 in Shanghai, SANITIZED (China) Ltd. will be showcasing on Booth D25, Hall N1, its long-lasting Sanitized® Swiss antimicrobial protection for flexible polymer applications.

In recent years, regulatory developments have limited the available types of biocides that can be used to protect polymers and textiles from bacterial and fungal growth. For example, the biocide OBPA was widely used to protect PVC and other plastics from such issues in the past, but the European Union blocked OBPA from sale in January 2013, prompting producers to seek other options. Commonly used alternatives such as DCOIT, BBIT, zinc pyrithione or IBPC have their own limitations, related to their use in various flexible polymer applications.

Outdoor applications in particular have seen an increase in performance requirements –– especially as regards antimicrobial effectiveness after exposure to water and ultraviolet light. Such additives also should not contribute to yellowing after UV exposure, but the available alternatives often fall short in this regard. And antimicrobial additives need to be able to meet the requirements for heat stability during the application process, while also avoiding initial discoloration and demonstrating compatibility with other additives in the formulation.

SANITIZED AG has developed a solution that addresses all these issues. Sanitized® PL 14-32 offers highly effective, long-lasting antimicrobial protection for flexible polymer applications. Besides thermal stability and compatibility with most formulations, Sanitized PL 14-32 provides high UV resistance and no yellowing after UV exposure, as well as good water resistance. It protects the target material against the unwanted effects of microbes such as bacteria, mold, mildew, yeast, pink stain and algae – all of which can destroy material, while also causing unsightly stains, cross contamination, odor development and biofilm formation. The product has been proven to deliver thermal and color stability, and efficient antimicrobial protection in several formulations. Further, it is supported under the EU`s Biocidal Products Regulation (BPR), and the U.S. Environmental Protection Agency has approved its active substances.

Aachen researchers have developed the adaptive textile facade green.fACade, which was presented on 2^nd August 2018 in the Aachen Faculty of Architecture of RWTH Aachen University, Germany. green.fACade is installed in front of a building like a second skin and can permanently reduce nitrogen oxide pollution in cities.

The researchers achieve the reduction of harmful nitrogen oxides (NO and NO2) by coating the facade with titanium dioxide. Titanium dioxide acts as a photo catalyst and enables the oxidation of nitrogen oxides to form washable nitrate (NO3-). Since the facade is also greened, it contributes to the conversion of carbon dioxide into oxygen by photosynthesis. In addition, a green facade creates an optical resting point in the cityscape and reduces urban heat through evaporation cooling. The enclosed pictures demonstrate how the introduction of green.fACade can have an effect. Picture 1 shows the Aachen Central Bus Station after, picture 2 before the possible introduction of green.fACade.

green.fACade is part of the innovative research project "adaptive textile facades", which uses the special properties of textiles. Thanks to its design, textiles can let sunlight and air through, thus contributing to a modern, aesthetic building design. A new feature of the research project is that further elements such as the titanium oxide coating or sun protection elements are integrated into the textile facade and placed in front of the existing building facade. The adaptive textile facade acts independently and thus reduces energy consumption through the positive climatic effects on the building facade.

"Adaptive Textile Facade" is part of a current research series with the aim of developing innovative facade constructions that are climate-neutral and increase the comfort of local residents. The research team consists of the three RWTH fields of architecture (Faculty of Architecture, PhD student architect M.Sc. Jan Serode), medicine (University Hospital RWTH Aachen, Clinic for Ophthalmology, Prof. Dr Walter) and textile technology (Institut für Textiltechnik, Prof. Dr Gries) and was able to contribute its expertise in the best possible way.

This summer the research team was supported for the first time by the Munich architectural office Auer Weber, represented by managing director Philipp Auer: "For us architects, developments in the field of textile outer shells are a special challenge. Here, highly developed textile materials and processing methods are combined with the lightness and grace of fabrics. Adaptive textile facade elements will increasingly turn the "building shell" into a "building skin", a system that not only offers weather, heat and sun protection, but is in constant intelligent exchange with its environment".

The great importance of these topics for the public was documented by the presence of Kirsten Roßels, representative of the Department of Economics, Science and Europe of the city of Aachen.  Ms Roßels explains: "As the city of Aachen, we are delighted with the innovative and future-oriented project ideas that are being developed at Aachen University, such as the adaptive textile facade. These developments underline the importance of Aachen as a city of science and I would appreciate it if these and other technologies could also become visible in Aachen in the future".

Prof. Dr Gries from the Institut für Textiltechnik sums up: "As textile researchers, we see a great opportunity to develop concrete solutions for our urban living spaces together with renowned experts from other disciplines. I'm sure we can make the urban climate more pleasant and reduce pollution."
