The Mechanical Engineering Industry Association (VDMA) has awarded two prizes to graduates of the Institut für Textiltechnik (ITA) of RWTH Aachen University - the dissertation prize and the creativity prize of the Walter Reiners Foundation of German Textile Machinery 2018. ITA alumnus Dr Benjamin Weise was awarded the dissertation prize for the development of novel fibres for textile charge storage devices. For their work on a guide to 4D product design, Jan Merlin Abram and Aalon Tal (both ITA students) were honoured with the creativity prize. The dissertation prize is endowed with €5,000 whilst the creativity prize contains a one-year scholarship of €250 per month. Peter D. Dornier, President of the Walter Reiners Foundation and Chairman of the Management Board of Lindauer DORNIER, presented the awards on the 18 September 2018 at the 18th Textile Machinery Forum in the Digital Capability Center in Aachen, Germany.

Graphene revolutionizes all-in-one - supercaps, reduction of terahertz radiation and antistatics

In his dissertation "Development of graphene-modified multifilament yarns for the production of textile charge storage devices", laureate Dr Benjamin Weise developed novel fibres made of polyamide and graphene and further processed them into textile surfaces. The newly developed polyamide graphene fibres are featuring a multitude of advantages:

• Due to their high performance in the charge storage area, they are predestined for use in double-layer capacitors, so-called super capacitors, or supercaps in short. Compared to lithium-ion batteries, supercaps offer significantly higher power density and a longer lifetime as no chemical reactions are taking place. towing to the graphene platelets in the filaments, it is now possible for the first time to integrate a charge storage device directly into a textile without having to sew in a rechargeable battery. This new fibre is therefore suitable for prospective use in smart textiles, for instance in a textile defibrillator.
• The new graphene-modified polyamide fibres can attenuate inident terahertz radiation up to 25 % of their original intensity. Terahertz radiation, for example, offers transmission rates of 100 Mbit/sec and is therefore of high interest for high-performance wireless communication. However, the radiation could damage sensible electronics as in aircrafts if this technology will be used widespread. Consequently, the shielding of the radiation is of high importance, e.g. in the form of fibre composite components in the aircraft, which protect the on-board electronics.
• As the fibres are showcasing a dissipative electrical conductivity, personal protective equipment is another prospective field of application.  

The development of a pilot process for graphene-modified fibres and the production of textile demonstrators are novel and disruptive attainments of Dr Weise’s PhD thesis and the reason for the award ceremony to him. Due to its outstanding properties, the European Union is funding research on graphene within the frame of the "Graphene Flagship" with an overall budget of one billion Euro (source: http://graphene-flagship.eu/project/Pages/About-Graphene-Flagship.aspx).

Modular product design of 4D products is now possible in simplified form

How can three-dimensional products change their shape over time and thus become "four-dimensional"? The students Jan Merlin Abram and Aalon Tal provide answers to this question in their project work "Leitfaden zur Auslegung hybrider morphender Textilien am Beispiel eines Scharniers" (Guidelines for the Design of Hybrid Morphing Textiles Using the Example of a Hinge), for which they were awarded the creativity prize. In their work, the students offer a guideline for the development of a four-dimensional textile from the idea to the demonstrator. Four-dimensional textiles, for example, consist of a hybrid material of elastic textile on which three-dimensional structures are printed. The fourth dimension describes the change in shape and/or a property over a defined period of time (= morphing).  This change is caused by external influences such as light and heat.

Every year, the Foundation of the German Textile Machinery awards prizes for the best dissertation, diploma or master's thesis and the creativity prize for the smartest student research project. Further prizes were awarded to Eric Otto, ITM Dresden, and Susanne Fischer, Reutlingen University.

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.

The Aachen Center for Integrative Lightweight Production (AZL) of RWTH Aachen University is installing a new ENGEL injection molding system in its technical center.

The research will address multi-material systems, continuous processes, process chains as well as self-optimizing processes.

Dr.-Ing. Michael Emonts, Managing Director of the Aachen Center for Integrative Lightweight Production (AZL) is looking forward to realizing new innovative lightweight production process with the new injection molding system: “This new injection molding system offers us as specialists for lightweight production technology in cooperation with the injection molding experts of the Institute of Plastics Processing – the IKV – the opportunity to establish hybrid processes for industrial lightweight applications. The system will expand our existing machinery in the AZL Technical Center and will be available as an important platform for lightweight production research at RWTH Aachen University.”

Being a Partner of the AZL, ENGEL has already been working closely with the AZL for many years as a Partner Company of the AZL Partner Network. Dr. Stefan Engleder, CEO of the ENGEL Group, emphasizes the importance of close collaboration with technical universities and especially with the AZL: “The AZL provides great conditions for industry-related research activities in the field of lightweight composites as it is characterized by a strong interdisciplinary approach. It benefits from the great infrastructure and the collaboration with well-known institutes of the RTWH Aachen University. ENGEL is looking forward to working together with the AZL on developing efficient lightweight composite mass production processes.”

In addition to the numerous composite and lightweight equipment at the RWTH Aachen Campus, the AZL Technical Center comprises large-scale equipment for the development of processes for lightweight production, such as a composite press from Schuler Pressen GmbH with 18,000 kN clamping force.

• Successful acquisition of Austrian plastics recycling company Ecoplast Kunststoffrecycling GmbH

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, announces today that it has fully acquired the Austrian plastics recycler Ecoplast Kunststoffrecycling GmbH (“Ecoplast”). Based in Wildon, Austria, Ecoplast processes around 35,000 tonnes of post-consumer plastic waste from households and industrial consumers every year, turning them into high-quality LDPE and HDPE recyclates, primarily but not exclusively for the plastic film market.

The expectation of Borealis is that the recycled PO market will grow substantially by 2021, which is the strategic rationale behind the acquisition. The company has made PO recycling a key element of its overall PO strategy because of its potential to support both growth and sustainability. Borealis has been an industry frontrunner in making polyolefins more circular. In 2014, it began offering high-end compound solutions to the automotive industry, consisting of 25% and 50% post-consumer recycled content. Borealis was also the first virgin PO producer to explore the possibilities of mechanical recycling, by acquiring one of Europe's largest producers of post-consumer polyolefin recyclates - mtm plastics GmbH and mtm compact GmbH – in July 2016. Since then it has continued to invest into the development of technology and new products in the area of circular polyolefins.

“Borealis recognises the increasing need for plastic recycling and sees the Circular Economy as a business opportunity. Borealis already has a long-term collaboration with Ecoplast and this acquisition is the next logical step in building our mechanical recycling capabilities. As an important complement to mtm in Germany, Ecoplast will help us address critical sustainability challenges and become a polyolefin recycling leader. Eventually, we want to use our experience to develop an effective blueprint for the end-of-use phases for plastics that can be applied in other parts of the world,” says Borealis Chief Executive Alfred Stern.

“We are very happy that the transaction with a strong and reliable partner such as Borealis has been successfully concluded and are looking forward to our common future activities on the recycling market. We have located potential synergies in many operative and strategic areas, especially in product quality R&D and future applications of polyethylene-film-recyclates. The combination of Ecoplast and Borealis holds the potential to be groundbreaking for the market,” says Ecoplast’s Managing Director Lukas Intemann.

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.

This September’s Cinte Techtextil China will once again provide a strong barometer of the state of the global technical textiles industry, and in particular which sectors in Asia as a whole, and China specifically, are performing well. Two of these for certain are Buildtech and Mobiltech, with a number of leading global and Chinese brands exhibiting to eager buyers from these sectors.

Cinte Techtextil China is Asia’s leading biennial fair for the technical textiles and nonwovens sector, and will feature an expected 500-plus total exhibitors from around 20 countries & regions from 4 – 6 September. The fair offers products and technologies for 12 application areas* which cover the entire industry.

Buildtech benefits from Belt & Road and other infrastructure investment

With a huge boom in national and regional infrastructure projects, the market for Buildtech products, especially geotextiles and construction textiles, is rapidly expanding. In particular, the government’s global Belt & Road project, as well as continued investment at home in highways, high-speed rail and more, is fuelling this expansion. According to CNITA, in 2017 China started 35 new railway projects, with additional private capital investment in this sector totalling some USD 53 billion that year. The same investment in highway construction increased 17.7%, while water conservation project investment by private firms reached a new record of USD 105 billion.

With this potential in the Asian market, it’s no surprise a number of new exhibitors will feature in the Buildtech sector at the fair, including FPC Technical Textile from Saudi Arabia, Kobe-cz from the Czech Republic, as well as Lenzing Plastics, while Johns Manville are one of the returning exhibitors this year.

• FPC Technical Textile (Saudi Arabia) produce high-end specialty fabrics including PVC coated fabrics and fibre glass PTFE fabrics, and will focus on the latter at the fair.

Trevira, one of the market leaders in polyester yarn manufacture, and the development services company imat-uve have together achieved a milestone in textiles design: the use of 3D flat knitting technology for automotive interiors. In a jointly developed process that unites innovative yarn technologies with cutting-edge connection and finishing techniques, Trevira and imat-uve have found a way of producing anatomically contoured seat covers and trim components for vehicle interiors. Why is this important? The answer lies in the way it's done. Because the technology uses just one knitting process rather than several, manufacturers can reduce their production and materials costs, as it's no longer necessary to cut and assemble the fabrics. But the new invention is not just cost-effective – the flat knitting technique means that it's now possible to personalise design and function to a much greater degree, representing another important step in the direction of on-demand production.

Trevira and imat-uve are the first companies to develop such a sophisticated application of the knitting process for use in vehicles, thanks to imat-uve’s innovative processing and finishing technique which deploys a low-melt yarn specifically developed by Trevira. The collaboration has resulted in a high-performing knitted product which satisfies even the most demanding criteria in terms of quality and comfort. The VDA 230-210 standard velcro test carried out by imat's testing laboratory found that the product was extremely abrasion resistant. The 3D flat knitting technology even means that areas known to be vulnerable, such as the seams on seat covers, can be strengthened in the course of the same single knitting process. Another benefit of the technology is its contribution to sustainable manufacturing. Not only does it work on the zero waste principle, but the knitted fabric itself is manufactured entirely from yarn made from PES recyclates.

Thomas Rademacher, Head of Development at Trevira, explains why the collaboration was so successful. "The development company imat-uve came up with a new breakthrough technology, while here at Trevira, we contributed our own recycled yarns and a new low-melt yarn we've developed based on synthetic fibres, which provides a stabilising effect. Together we have created a highly sought-after, top quality product for automotive interiors. Flat knitting will now be the go-to technology for vehicle interiors – in the future, it will be impossible to imagine life without it."

Hans Peter Schlegelmilch, imat-uve’s CEO, pointed out the especial benefits of the new technology for vehicle manufacturers and their suppliers. "The 3D flat knitting technology doesn't just make it possible to save time and money on production. It also opens up a whole new world of personalisation for end consumers. We are extremely pleased that with Trevira as our partner, we have been able to take this significant step towards the future of automotive interiors."
