From the Sector

Monforts textile technologist Jonas Beisel will outline the benefits of the company’s Econtrol® continuous dyeing process during the next free-to-attend VDMA Textile Machinery Webtalk which takes place on February 3rd 2022 at 13.00 (CET).

“Our customers are increasingly looking at shorter production runs and the more economical use of dyestuffs, as well as reducing water and energy consumption,” says Beisel. “We have gained many years of experience in the optimisation of dyeing processes through working with our customers, both at their own plants and in our Advanced Technology Centre (ATC) in Mönchengladbach, Germany.

“Our Thermex universal hotflue for continuous dyeing, curing and thermosoling achieves unrivalled reliability even at high fabric speeds, for exceptional cost-effectiveness when dyeing both large and small batches of woven fabrics. The Econtrol® process for reactive dyestuffs now has an impressive number of references on the market, as a quick and economical one-pass pad-dry and wash off process. This is the ideal process for fast change technology and operational savings.”

Among key benefits are the saving of resources compared to conventional continuous dyeing methods, excellent reproducibility of pale to dark shades, from lab to bulk, and greater flexibility in production planning due to a resulting dry fabric that does not need an immediate wash off.

Econtrol® is a registered trademark of DyStar® Colours Distribution GmbH, Germany, and Bertram Seuthe of DyStar® will be providing recommendations for dyes and auxiliaries for the process during the VDMA event.

A third speaker, Guido Seiler of Fong’s Europe, will explain how Goller washing ranges help to significantly reduce the water that is conventionally wasted in the washing off process, through a combination of process and chemistry know-how and advanced technologies.

On 27 November 2021, the Scientific Award for International Sustainable Aviation and Energy Society (SARES Award) was awarded to Professor Dr Thomas Gries from the Institut für Textiltechnik of RWTH Aachen University. The award ceremony took place during the closing ceremony of the International Symposium on Sustainable Aviation (ISSA) in a hybrid format online and simultaneously at Kasetsart University, Bangkok, Thailand.
 
With the award, the committee recognised the ongoing contribution of Pro-fessor Gries and the Institut für Textiltechnik to the digitisation and bio-transformation of the textile sector, as well as the Institute as a place of innovation for sustainable aviation.

Examples of this include the development of 3D braided ceramic matrix composite components for aircraft engines, which were researched together with partners in a Horizon 2020 project (EU project AllOxITD). The ongoing Chrysomallos research project as another example, funded under the national aeronautics research programme in Germany, aims to develop a completely new and sustainable high-performance insulator for aircraft cabins based on aerogels. These have a significantly lower weight than the glass fibre mats used up to now, while providing the same insulation performance, and solve the problem of the previously high manufacturing costs of aerogels. The aim of the project is to develop an insulation material with reduced density (reduction of more than 20 percent). To this end, a new type of insulation material based on aerogel is to be developed. The basis is an aerogel fleece (0.06 W/mK at 28 kg/m³), which has already been developed as part of a dissertation at the Institut für Textiltechnik of RWTH Aachen University (Mroszczok, J.: 2019).

The aviation industry is one of the fastest growing industries in the world. Due to this fact and its importance for society and the global economy, it needs to make special efforts towards sustainability. The ISSA, an international multi-disciplinary symposium, aims to address current issues in aviation such as improving aircraft fuel efficiency, promoting the use of biofuels, minimising environmental impact, mitigating greenhouse gas emissions and reducing engine and aircraft noise. ^

Through the award, SARES honours scientists and researchers whose work on sustainable aviation issues has made an important contribution at the international level. The selection is based on the scientific publications of the applicant or nominee, the h-index, i.e. the key figure for the worldwide perception of a scientist in professional circles, the project topics and the project results.

Travis Wells, JD, MBA, has been appointed as GOTS Protection Officer North America. In this newly created position, he will be identifying and advising companies that are making unsubstantiated claims regarding GOTS signage.

An increasing number of companies are eager to use GOTS certified materials and want to make claims regarding GOTS content on their finished products. However, the correct use of the trademarked logo is strictly regulated in CUGS 3.1. – The conditions for the use of GOTS signs. A GOTS claim on finished products guarantees the consumer that every single step in the textile processing supply chain was certified. As soon as one stage in the supply chain is not certified, a company may not label or mention GOTS on their final product.

As a Sustainable Supply Chain Director, Travis has more than 20 years of experience advising fashion and apparel-related businesses on sustainable sourcing, product development and manufacturing in domestic and global markets. He earned his Bachelor of Arts (B.A.) in International Studies from Vassar College, his Juris Doctorate (J.D.) in Corporate Law from George Washington University Law School and his Master of Business Administration (MBA) in Global Sustainability and Finance from the Gabelli School of Business at Fordham University.  

At the subsidiaries of the German Mahlo GmbH + Co KG, two branch managers are celebrating anniversaries this year. Alan Lavore, CEO of Mahlo America Inc., has been with the machine builder for 25 years. Michel Bruni, CEO of Mahlo Italia, has been part of the Mahlo family for 40 years.

Bruni began his career at Mahlo in 1981 as a service technician in the French branch Mahlo Ouest. Just one year later, he moved to Mahlo Italia, where he was appointed branch manager in 1996. He still holds this position today. Bruni is also sales manager for the Benelux countries, the Maghreb countries and Madagascar. The Mahlo Italia CEO's recipe for success includes expertise paired with experience and passion. To remain loyal to a company for so many years also testifies to a special relationship. "Then as now, I work with a dynamic and committed team. We also have a very good relationship with the employees of the parent company in Germany," says Bruni.

The culture and integrity with which business is conducted in the family-owned company were among the reasons why Mahlo America Inc. CEO Alan Lavore has also been with Mahlo for 25 years. "I just love working with all the great people at Mahlo." Lavore joined Mahlo in 1996 as a territory sales manager and took over as CEO in 2005. During this time, he drove the company's expansion from a textile specialist to a supplier for various production sectors such as film, paper, coating and converting or nonwovens.

Die Verleihung der Förder- und Kreativitätspreise 2021 der Walter Reiners-Stiftung des VDMA, Fachverband Textilmaschinen an Studierende und Nachwuchswissenschaftler:innen deutscher Universitäten für Spitzenleistungen in Studium und Promotion fand am 09. November 2021 im Rahmen der Aachen-Dresden-Denkendorf International Textile Conference 2021 statt. Die bundesweit ausgeschriebenen Förder- und Kreativitätspreise wurden erneut online durch Herrn Peter D. Dornier, Vorstandsvorsitzender der Walter Reiners-Stiftung, verliehen.

Dr.-Ing. Martin Hengstermann wurde mit dem mit 5.000 EUR dotierten Förderpreis beste Dissertation des Deutschen Textilmaschinenbaues 2021 für seine am Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik der TU Dresden erarbeiteten Dissertation „Entwicklung von Hybridgarnen aus recycelten Carbonfasern und Polyamid 6-Fasern für thermoplastische Verbundbauteile mit hohem Leistungsvermögen“ geehrt.

Gegenstand der Dissertation ist die Entwicklung und Umsetzung von neuartigen Hybridgarnen aus recycelten Carbonfasern (rCF) und Polyamid (PA) 6-Fasern für thermoplastische Verbundbauteile. Diese Hybridgarne können die hervorragenden mechanischen Eigenschaften der rCF im Gegensatz zu bisherigen Lösungen in hohem Maße ausnutzen. Bedingt durch deren spezielle Fasereigenschaften (insbesondere hohe Querkraftempfindlichkeit, Sprödigkeit und fehlende Kräuselung) wurde dafür die Prozesskette der konventionellen Stapelfasergarnherstellung, bestehend aus Krempel, Strecke und Flyer, umfangreich analysiert und technologisch-konstruktiv weiterentwickelt, wodurch erstmalig eine schonende und gleichmäßige Herstellung der Hybridgarne ermöglicht werden konnte.

The Chairman of the Walter Reiners-Stiftung foundation of the VDMA Textile Machinery Association, Peter D. Dornier has awarded prizes to three successful young engineers. The award-winning works provide practical solutions on the topic of circular economy. For example, the recycling of carbon fibres, which are used to produce lightweight components for the automotive industry. Or the environmentally friendly production of yarns from crab shells. Another topic was medical applications: The processing of ultra-fine yarns into stents for aortic repair. The award ceremony took place online on 9 November as part of the Aachen-Dresden-Denkendorf International Textile Conference.  

With a creativity prize, endowed with 3,000 euros, the foundation honoured the diploma thesis of Irina Kuznik, TU Dresden. She used a creative approach to realise solutions for processing chitosan into fibre yarn.

Mr Kai-Chieh Kuo was awarded the diploma/master's thesis promotion prize of 3,500 euros. With his master's thesis, which was written at RWTH Aachen University, Mr Kuo contributes to the production of vital components used in medicine. The stents made of ultra-fine yarns are made possible by an innovative modification of the classic tube weaving process.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."   

It looks like a normal shirt, but it has it all: The new SmartTex shirt uses integrated sensors to transfer physiological data from astronauts to Earth via a wireless communication network. In this way, the effects of the space environment on the human cardiovascular system will be evaluated and documented, especially with regard to long-term manned space missions. Developed by the German Aerospace Center (DLR) in cooperation with DSI Aerospace Technology, the Medical Faculty of Bielefeld University and textile research partner Hohenstein, SmartTex will be tested for the first time as part of the Wireless Compose-2 (WICO2) project by German ESA astronaut Dr. Matthias Maurer, who will leave for his ‘Cosmic Kiss’ mission on the International Space Station (ISS) for six months on October 30, 2021.

"We were already able to gain valuable insights into the interaction of the body, clothing and climate under microgravity conditions during the previous projects Spacetex (2014) and Spacetex2 (2018)," explains Hohenstein Senior Scientific Expert Dr. Jan Beringer. The insights provided at the time by the mission of ESA astronaut Dr. Alexander Gerst have now been directly incorporated into the development of the new SmartTex shirt at Hohenstein. "Matthias Maurer can wear his tailor-made shirt comfortably on his body during his everyday work on the International Space Station. For this, we used his body measurements as the basis for our cut development and the production of the shirt. We integrated the necessary sensors as well as data processing and communication modules into the shirt's cut in such a way that they interfere as little as possible and are always positioned in the right place, regardless of the wearing situation. This is the prerequisite for reliably measuring the relevant physiological data." The SmartTex shirt is intended to provide a continuous picture of the vital functions of astronauts. This will be particularly relevant for future long-term manned space missions to the Moon and Mars.

For example, during the BEAT experiment (Ballistocardiography for Extraterrestrial Applications and long-Term missions), Matthias Maurer will be the first astronaut to wear a T-shirt equipped with sensors that measure his ballistocardiographic data such as pulse and relative blood pressure. For this purpose, the sensors were calibrated in the :envihab research facility at the DLR Institute of Aerospace Medicine in Cologne. Details on the contraction rate and opening and closing times of the heart valves, which are normally only accessible via sonography or computer tomography, can also be read from the data material. The goal is to study the effects of the space environment on the human cardiovascular system. To be able to analyse these effects realistically, Matthias Maurer's ballistocardiographic data will be recorded before, during and after his stay on the ISS. For the future, a technology transfer of the SmartTex shirt for application in the field of fitness or even in telemedicine is conceivable.

Wireless Compose-2 (WICO2)
The project was planned and prepared by the German Aerospace Center (DLR) and its cooperation partners DSI Aerospace Technology, Hohenstein and the University of Bielefeld. The wireless communication network reads sensor data and can determine the position of people and objects in space by propagation times of radio pulses. It is also available as a platform for several experiments on the ISS. The determined data is temporarily stored within the network and read out at regular intervals by the astronauts. These data packets are then transferred to Earth via the ISS link and analysed by the research teams. It can generate its own energy from artificial light sources via solar cells.

Schoeller Textil AG, the Swiss textile and technology company, announces a shift in leadership as Joachim Kath takes over as CEO. Following a 10-year career at the global textile solutions brand, CEO Siegfried Winkelbeiner is moving into his retirement later this month. Joachim Kath, who comes from the chemical industry, has been working closely with Winkelbeiner as COO at Schoeller for the past year and a half.

The transition comes after long-term planning. Since February 2020, and in close partnership with Siegfried Winkelbeiner, Joachim Kath (on the left) has been preparing as Schoeller COO to take over its management. Joachim Kath originally comes from Flensburg (DE) and, following his studies of Chemical Engineering in Karlsruhe, shaped his professional career in the chemical industry with Ciba (-Geigy) / BASF in Basel (CH). His career over 30 years has incorporated engineering, production and marketing & sales in diverse management functions – in a wide range of business segments for various industries and areas of application around the globe. Joachim Kath spent 12 years of his career dedicated to textile finishing, with a period of intensive travel in Asia and a 3-year stay in the USA.

Asked how he sees himself, Joachim Kath said: “The common thread running through all my assignments and business activities is process orientation, interest in new paths, and an instinct for what is feasible – with the goal of achieving customer benefits and satisfaction. Kath aims to ensure that Schoeller can continue to face the challenges of changing market requirements with outstanding and exceptional products, while evolving and innovating to stay ahead of consumer needs for the future. High performance capability, sustainable product development, premium quality, reliability, productivity, and keeping the customer as the central focus of all activities continue as essential keys to Schoeller’s continued business success.

• Excellent project to encourage ingenuity among young students
• Experiment on biodegradability of textiles and nonwovens produces impressive results
• EUR 30,000 in prize money for a total of 209 participating schools in and outside Austria
• Lenzing views supporting these kinds of projects as part of its sustainability mission

Lenzing – The Association of Chemistry Teachers in Austria – known by its German abbreviation, VCÖ – has been holding project competitions that thrill students and take them beyond the traditional syllabus for 30 years. Every two years, it highlights a key topic for ninth- and tenth-graders to explore by conducting special experiments and learning from their observations and conclusions.

This year, the 16th installment of the competition is called, “Achieving a cleaner climate and a circular economy with chemistry”. These topics are also near and dear to the heart of globally active fiber manufacturer Lenzing. That’s why the company promptly announced that it was prepared to support this project competition in several different ways. First, Lenzing made a contribution toward the sponsorship fund totaling EUR 30,000. Second, it initiated a special prize on biodegradability – a topic of growing importance given the huge challenges involved in reducing plastic waste. Finally, Lenzing placed a recognized expert at the students’ disposal to provide assistance and answer questions: Michaela Kogler, Project Manager Nonwovens & Technical Products.

Teaming up with rainworms

Two teams were tasked with biodegrading different fibers – just like those used to produce textiles and nonwovens – with the active participation of worms. Students at BRG solarCity in Linz buried fiber nonwovens, a basic material used in wet wipes and other products, in soil that was populated with numerous rainworms, while students at Vöcklabruck Junior High School for Sports and Integration layered textiles into a vermicomposting bin. Both experiments intended to determine the extent to which certain materials would biodegrade quickly. As it turned out, both projects showed that wood-based fibers, like those that Lenzing manufactures for the textile and nonwoven industry, break down very rapidly into natural constituents that swiftly pass into the soil. In contrast, fossil-based plastics such as polyester or polyethylene cannot be decomposed by worms or bacteria but remain in the soil, sometimes for hundreds of years.

The prizes for this year’s competition were awarded on June 11. The competition attracted entries from no fewer than 209 schools, including 11 from outside Austria. For more information on the projects and the winners, visit www.vcoe.or.at.
