Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.

• ANDRITZ receives an additional order for a high-speed spunlace line from Zhejiang Kingsafe, China

International technology Group ANDRITZ has received an order from Zhejiang Kingsafe Hygiene Materials Technology Co., Ltd. in Hezhou, China, to supply a complete new neXline spunlace line. The line is scheduled for installation and start-up during the second quarter of 2022.

This high-capacity spunlace eXcelle line will process either 100% biodegradable fibers or blends of polyester and viscose. It is dedicated to the production of hygiene and medical fabrics. The final products will have fabric weights ranging from 30 to 100 gsm, and the annual production capacity will be up to 18,000 tons.

ANDRITZ will deliver a complete line, from web forming to drying, also integrating two high-speed TT cards, the well-known JetlaceEssentiel hydroentanglement unit and the neXdry through-air dryer equipped with a neXecodry S1 system for energy saving. This combination is becoming the market benchmark for the production of lightweight spunlace fabrics dedicated to the hygiene market.

“We are proud to operate ANDRITZ nonwoven lines, which are very reliable and efficient. It helps us a lot in producing top-of-the-range, nonwoven roll goods, thus enabling us to be recognized as a key player among nonwovens producers worldwide,” says Kingsafe’s president, Mr. Huarong Yan.

Zhejiang Kingsafe Hygiene Materials Technology Co., Ltd., founded in 1987, is one of the largest companies in China producing spunlace and spunbond nonwoven roll goods, with several spunlace lines already in operation. The final products are exported all over the world and used in many fields, such as the medical sector, health care, high-tech agriculture, and high-quality consumer and household products.

The new line is now the ninth spunlace line supplied by ANDRITZ and the third with high-speed TT cards, thus confirming the successful, long-term partnership between ANDRITZ and Zhejiang Kingsafe. The order also proves that the solution provided by ANDRITZ is recognized as the benchmark for production of premium spunlace roll goods and contains the perfect combination for wipes converting machines.

International technology Group ANDRITZ has always been at the forefront in providing innovative and sustainable solutions for the global nonwovens industry. Optimization of resource management, especially reducing the consumption of raw materials and other substances used and also keeping resources in use for as long as possible, are decisive factors in enabling nonwovens producers to offer competitive and sustainable products.

As a world market leader for nonwovens production equipment and services, ANDRITZ offers a full range of products to meet these challenging demands.

Maximizing the evenness of the product across the entire production line is one of the key success factors. The weight profiling product range of ANDRITZ – consisting of ProDynTM and ProWidTM – has been extended by ProWinTM. This new development is the combination of the two existing systems ProDynTM and ProWidTM. It allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15% at the same time. ProWin combines the long-term process experience and in-depth knowledge ANDRITZ has on needlepunch lines with innovative software to synchronize action across the line. Guillaume Julien, Head of Needlepunch Sales at ANDRITZ Nonwoven, explains,

“We have developed a self-regulating, advanced technology to reduce fiber deposits at the edges of the web and eliminate the “smile” effect across its width. ProWin enables producers to optimize the CV ratio autonomously and precisely while also generating significant fiber savings of up to 10% and increasing production speed. Thus, it also provides a faster ROI.“

When it comes to the spunlace process, a better product quality can be obtained by ensuring that the different equipment units in the production line are consistent with one another. The TT card, the Jetlace hydroentanglement unit, and the neXdry through-air dryer are the perfect combination to obtain premium visual quality and characteristics in the web. For an equivalent amount of fibers, this set-up is designed to produce an even web with significant bulkiness and an excellent MD:CD ratio without impacting the production capacity.

Maximizing performance by minimizing the raw material input and the amount of waste produced is a real driver of cost optimization. This is why ANDRITZ has created and integrated a solution that allows nonwovens producers to retrieve the wasted edges of their spunlace fabric and re-use it as recycled fibers. As a result, roll-good producers can even obtain the same web characteristics as when using virgin fibers, and most importantly, the exact same quality.

ANDRITZ also offers – under the brand Metris – ANDRITZ digital solutions – a variety of several service apps for optimum customer benefit. The Metris Cost Management app is used to track raw material consumption. It is an advanced system aimed at monitoring fiber consumption and allowing in-depth diagnoses to investigate raw material losses and savings grouped by different process areas. Thanks to this Metris application, ANDRITZ customers are able to optimize their system’s consumption of raw materials.

All these innovations are available in ANDRITZ’s technical centers, where ANDRITZ process experts will be glad to welcome customers in order to discuss and define their product expectations.

Paper Converting Machine Company (PCMC) has announced its industry-leading wet wipes folding machines the Rx200 and Mako Clipper are now available with high-content alcohol, measuring as much as 70 percent.

Previously, PCMC wet wipes machines operated with less than 20 percent alcohol, producing disinfectant wipes for personal, home, industrial and automotive use. However, the COVID-19 pandemic has created a spike in demand for sanitizing wipes that contain at least 70 percent alcohol, the key component in killing or deactivating viruses.

To help manufacturers meet the increased demand, PCMC redesigned its Rx200 and Mako Clipper to safely operate with high-content alcohol. The new designs feature increased air exchange for better ventilation and additional sensors to eliminate the risk of flash points and fires. The machines also include IDS 150/300 integrated dual stackers and a redesigned Mako saw to meet more stringent regulations and higher machine performance expectations.

International technology Group ANDRITZ has received an order to supply four new needlepunch lines for nonwoven production from Chongqing Double Elephant Microfiber Material Co., Ltd., China. These lines are scheduled for installation and start-up in the fourth quarter of 2021.

The needlepunch lines by ANDRITZ are designed to process islands-in-the-sea fibers dedicated mainly to the production of high-quality synthetic leather products. Once completed, the lines will produce 30 million meters a year of microfiber nonwoven materials.

The production lines are equipped with an ANDRITZ carding machine and the newly developed Profile® crosslapper as well as the advanced-technology ProWid closed-loop system from ANDRITZ. The system can monitor the weight uniformity (CV%) of the entire product online and predict the weight distribution changes caused by the bonding process. In addition, the web weight can be reduced by controlled stretching, which solves the issue of fiber accumulation at the edges caused by traditional crosslapping methods. Both the weight and the uniformity of the product can be automatically adjusted via the closed-loop function as set on the ANDRITZ gauge.

Chongqing Double Elephant Microfiber Material Co., Ltd., wholly owned by listed Wuxi Double Elephant Microfiber Materials Co., Ltd., is located in the Changshou National Economic and Technological Development Zone of Chongqing City. The company is active in the research, development and manufacture of microfiber materials, polyurethane synthetic leather and polyurethane resin.

• 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”.

Patients as well as air-condition and ventilator systems spread SARS-CoV-2 virus as aerosols which settle on surfaces and remain there infective for more than 72 hours. That‘s why the pandemic has triggered an intensive search for Personal Protective Equipment PPE whose surfaces have antiviral properties, e.g. are able to bind and inactivate adhering virus.

In this context the chemical stability of the materials being used for PPE, polypropylene PP and/or polyester PET, is a challenge. More precisely, the absence of so-called ‘functional groups‘, like -OH, -COO-, -NH3+ at the material‘s surface. These groups are the fundamental basis for surface chemistry – specifically for attaching antiviral compounds onto the surfaces of man-made fibers.

Antiviral surface modification with the basic amino acid Arginine Arg is a new approach to inactivate SARS-CoV-2. - bionic surfaces‘ - development was tested according to ISO 18184:2019 „Determination of antiviral activity of textile products“ at Institute for Virology and Immunology at University Wuerzburg, Germany. - The finding: „[Six hours] incubation on [Arginine] coated NW reduced viral infectivity by more than five orders of magnitude.“ In other words: An amount of, for example, 10.000.000 virus is reduced to 100 (by five orders of magnitude).

- bionic surfaces – has more than 30 years experience in wet-chemical surface modification of man-made polymers like PDMS, PP, PE, PTFE.
