• Patterning from the cloud
• SwapKnit – KARL MAYER's first Smart Machine function revolutionizes the way of guide bar control

A view of machine data from anywhere and at any time, service support as if on site but from far away, patterning from the cloud: digitalization offers completely new possibilities in warp knitting, which KARL MAYER is using to offer its customers a wide range of advantages for their business. In doing so, the world market leader is pursuing a well thought-out strategy: coordinated innovation activities are being used above all to rethink aftersales support and machine maintenance, and to develop coordinated offers in three areas. These are Care Solutions, Digital Solutions and Smart Machine.

Smart Machine comprises special functions that are backed by KARL MAYER's expertise and enable customers to maximize their productivity. In addition, a previously unattainable reproducibility of quality is possible.

A first solution for this is SwapKnit. The new patterning concept manages completely without pattern discs, but still enables the high operating speeds typical of mechanical guide bar drives. The basis for this is the networking of the machine via the k.ey device with the KM.ON cloud.

• Speed of operation and pattern change
• Lapping procurement per individual purchase or flat rate
• Best article reproducibility

Further steps to follow
As the first Smart Machine offering, SwapKnit marks the start of digital innovations with which KARL MAYER offers its customers more benefits from its machines. Further innovations will follow.
"In our development activities, in addition to the important topics such as more speed and flexibility, we also have simplified handling and the possibilities of automation in mind. We want maximum efficiency with minimum operating effort," says Kay Hilbert.

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.

This E. Schneider has informed the Board of Directors that, after 13 years of membership, he will not stand for re-election as a member of the Board of Directors and Vice Chairman of Rieter Holding AG at the next Annual General Meeting on April 7, 2022.

The Board of Directors of Rieter Holding AG will propose Sarah Kreienbühl and Daniel Grieder for election to the Board of Directors at the Annual General Meeting on April 7, 2022.

Sarah Kreienbühl has been a member of the Executive Board of the Federation of Migros Cooperatives since 2018 and heads among other things Human Resources and Communications of the Migros Group. Before that, she spent 14 years at Sonova as Group VP Corporate Human Resources, where she was also responsible for Corporate Communications from 2012.

Kai-Chieh Kuo, PhD student at the Institut für Textiltechnik (ITA) of RWTH Aachen University, was awarded the German Textile Mechanical Engineering 2021 Best Master's Thesis Award for his master's thesis entitled "Modification of the tube weaving process of fine yarns for the production of woven ultra-low profile stent grafts". The prize is endowed with 3,500€. Peter D. Dornier, Chairman of the Board of the Walter Reiners-Stiftung (Foundation), virtually presented the award on the occasion of the ADD International Textile Conference on 9 November 2021.

Minimally invasive endovascular aortic repair (EVAR) with textile stent-graft systems is nowadays a clinically established therapy procedure for the treatment of abdominal aortic aneurysms (AAA) – pathological bulges of the aorta. Due to the thick profile of the folded stent graft systems, there is currently a high risk of injuring narrowed or highly angulated access vessels from the inside during implantation. Stent graft systems with smaller profiles could provide an improvement, which could overcome complicated access routes through a lower bending stiffness. One possible approach for reducing the system profiles is the use of thin-walled tubular woven fabrics made of ultrafine multifilament yarns (≤20 dtex) as graft material.

Up to now, it has not been possible to process the fine yarns with the required high thread density (>200 threads/cm) and the available weaving technology in order to guarantee sufficient tightness against blood.

In his master's thesis, Kai-Chieh Kuo made high-density tubular weaving of ultra-fine filament yarns possible for the first time by means of suitable modifications to a shuttle loom as well as adaptations in the weaving preparation. In particular, he developed a new innovative reed technology that reduces warp thread friction during the shedding process and thus improves the process stability of the dense tube weaving process of fine yarns.

With the help of the process modification, it was then possible to produce high-density, thin-walled tubular woven fabrics, which were positively evaluated with regard to their suitability for a stent graft. Above all the potential of these tubular fabrics lies in their extremely thin-walled fabric profile, which seals well against blood. By using these new types of tubular fabrics as graft material for stent grafts, the system profile of the folded stent graft system can be reduced without having to compromise the blood tightness of the implant. The technology developed by Mr Kuo is not only applicable to stent graft systems, but also offers great possibilities for use in all other endovascular implants such as trans catheter heart valves, covered stents and small-lumen vascular prostheses.

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."   

Indorama Ventures Public Company Limited announced it has strengthened its Indorama Management Council (IMC) – the company’s highest operational management committee – by rotating experienced executives and adding the COOs of the Fibers and Integrated Oxides & Derivatives (IOD) segments.

The elevation of Mr Christopher Kenneally, COO of Fibers, and Mr Alastair Port, COO of IOD, to the IMC – will enable more agile decision making as they build their high-growth segments into self-sustaining organizations that maximize value for IVL stakeholders. The appointments are effective immediately.

In a rotation of roles, Mr Sanjay Ahuja, the current CFO of IVL, will switch to Interim COO of Combined PET (CPET) for a period of 2 years, effective January 2022, as part of a rotation of senior expertise across the IMC. He will report to Mr D K Agarwal as CEO, who will take on additional broader responsibilities as CFO. The CPET role rotation will enable new dynamism in this largest segment of IVL and establish a self-sustaining organization for the permanent successor that IMC selects over this period. Mr Agarwal will be supported by Mr Ashok Jain in an enhanced role as Controller, covering Banking & Finance, Global Consolidation, Taxation and M&A.

Further, Mr Klaus Holz will join the IMC as Chief Human Resources Officer, effective 1 January 2022. He replaces Mr Roberto Bettini who will retire at the end of 2021.

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.

• Rieter CAMPUS strengthens innovation strategy and technology leadership position
• Customer and technology center and administration building ready for occupancy in 2024
• Commitment to the Winterthur site and to Switzerland as a business location

On September 8, 2021, the foundation stone was laid for the Rieter CAMPUS on the western part of the Rieter site at the Winterthur location, which includes a customer and technology center as well as an administration building. The Rieter CAMPUS will make an important contribution to the implementation of the innovation strategy and to the enhancement of the company’s technology leadership position. At the same time, the investment of around CHF 80 million is a commitment to the Winterthur site and to Switzerland as a business location. 

With a floor area of over 30 000 m2, the Rieter CAMPUS offers space for around   700 ultra-modern workplaces. For this purpose, Rieter and a specialist in office architecture have developed a contemporary space concept for the “Open Space Office” that is tailored to the needs of the company, divided into meeting rooms, focus rooms and some individual offices. The underground car park provides   88 parking spaces, and a further 12 outdoor parking spaces are being created   in front of the technology center.  “In the course of its 225-year company history, Rieter has helped shape the city of Winterthur. The foundation for the future as a leading technology company is now being created with the new CAMPUS. In this way, Rieter is giving a clear indication   of its commitment to the Winterthur site and to Switzerland as a business location”, commented Bernhard Jucker, Chairman of the Board of Directors of Rieter Holding AG.

Innovation is an important part of Rieter’s strategy and crucial for the company’s success. For this reason, Rieter invests more than CHF 50 million annually in research and development. Thanks to this commitment, Rieter is making a   decisive contribution to the further development of systems for sustainable yarn production and their digitization. The Rieter CAMPUS will provide an attractive working environment that promotes creativity and innovation.  The new CAMPUS is a showcase project in terms of economic feasibility, energy efficiency and sustainability. Rieter relies on renewable energy for construction. This includes heat generation via geothermal probes and a photovoltaic system on around 1 300 m2 of roof area. “In this way, the entrepreneurial focus on sustainable and energy-efficient solutions for yarn production is reflected in the overall concept of the CAMPUS,” emphasized Rieter CEO Norbert Klapper.  The move into the new building is planned for 2024.
