From the Sector

With its current position paper, the Industrievereinigung Chemiefaser e.V. takes a stand on the intense discussions about an embargo against Russian natural gas supplies. The association believes that Germany's economic and global political future can only be secured with a strong industrial base and therefore, weighing up all positions and influencing factors and assessing the consequences for labour and the market economy, cannot support a short-term natural gas embargo on Russia.

An interruption of the continuous supply of natural gas would result in immense losses for the chemical fibre companies, which could even lead to the destruction of the industry in Germany. The losses are made up of technical damage caused by an uncoordinated shutdown of plants on the one hand and market-related consequential damage caused by lost production and a lack of product sales on the other.

Depending on the location and size of the plants, a short-term outage due to a lack of natural gas would result in average losses of EUR 5 million/plant. In addition, an ongoing daily loss would have to be expected which could be in the order of e.g. 250 000 EUR/day/plant, depending on the location. Furthermore, restarting the plants is questionable if supply chains could no longer be serviced and customers globally look for other suppliers in the meantime. Thus, entire sites would be at risk. With China's global market share in man-made fiber production already exceeding 70 %, a scenario is more than realistic that China will also take over these supply chains, thus leading to an even greater dependence on China.

The vast majority of power plants used for the production of man-made fibers, especially the highly efficient combined gas-and-steam power plants based on the principle of cogeneration with efficiencies of 90 %, are designed exclusively for the use of natural gas. Quite often, there are no technical facilities for operating gas turbines or steam boilers with fuels other than natural gas. Only in exceptional cases could a switch be made to mineral oil. However, even in these cases, the necessary stockpiling of mineral oil is designed only for a short-term failure of the gas burners. A change to base-load supply with mineral oil could take a time window of between 3 and 56 months, depending on the type of plant and taking into account licensing requirements. The use of hydrogen as an energy source is only possible in the very long term. In the few cases where natural gas can be substituted, investment costs of EUR 250 million/plant can be incurred, depending on the emission level of the converted plant.

A natural gas embargo imposed by the European Union on the Russian Federation would not only mean the cessation of production and the end for man-made fiber producers, but also for other industries such as basic chemicals, paper, metal production and glass and ceramics manufacturing, as well as their related sectors. As the German economic institute Institut der Deutschen Wirtschaft Köln e. V. (IW Köln) concluded in its summary report 40/2022 of April 2022: "No one can accurately predict what future these businesses would then still have in Germany. That would be an unprecedented development."

Carbon dioxide-based fibre for climate protection and interdisciplinary training with novel Smart Textiles test rig

The Wilhelm-Lorch-Stiftung, based in Frankfurt am Main, Germany, honours a project of the Institut für Textiltechnik of RWTH Aachen University, short ITA, and awards a sponsorship prize to the ITA graduate Ricarda Wissel on 25 June 2020. She is awarded for her outstanding bachelor thesis " Implementation of elastic yarns made from carbon dioxide based thermoplastic polyurethane in socks " with funding for a subject-specific continuation of her education. The ITA receives the project sponsorship prize for the project "Smart Textiles - an interdisciplinary training course to promote young scientists in future technologies", which was submitted to the Wilhelm-Lorch-Stiftung by ITA´s PhD candidate Simon Kammler.

Carbon dioxide-based fibre from industrial waste contributes to climate protection

ITA scientist Dr.-Ing. Pavan Manvi has developed a melt spinning process at ITA for the production of elastic yarn from thermoplastic polyurethane, in which carbon dioxide is used as one of the raw materials. In her bachelor thesis, Ricarda Wissel successfully developed a process chain for the CO2-based yarn in a textile end product for the first time. In cooperation with the company FALKE and Dr Manvi, who supervised Ms. Wissel's work, the yarn was used to produce a sock (see figure "FALKE sock with carbon dioxide filaments").

By reusing carbon dioxide from industrial waste as a raw material for textile and clothing products, the carbon dioxide balance can be improved and thus contributes directly to climate protection. The sponsorship prize of the Wilhelm-Lorch-Stiftung is endowed with 6,000 € for the specialist further training of Ms. Wissel.

Interdisciplinary training with development of a new type of measuring stand for the future-oriented research field "Smart Textiles

The development of textiles with additional digital functions, so-called "Smart Textiles", is considered a future-oriented field of research. In his project submission, ITA´s doctoral candidate Simon Kammler presented a concept for a lecture series on Smart Textiles at ITA and develops a new type of measuring stand for measuring the capacity and conductivity of fibres. The project is funded by the Wilhelm-Lorch-Stiftung with a prize money of 10,000 Euro.

Smart Textiles enable the textile to interact with the environment and the human user. Today they are therefore in demand in many areas of everyday life such as sport, health, living, life and mobility and offer completely new practical solutions. In combination with digital networked services, Smart Textiles promise support and innovation in almost all situations of daily life.

With the conception of a new lecture series, Mr. Simon Kammler is supporting ITA in its goal of providing the best possible training for young scientists. The focus is on imparting far-reaching interdisciplinary skills in order to master the challenges of current fields of research.

Background:

The Wilhelm-Lorch-Stiftung supports particularly talented young people from all areas of the textile industry. Its purpose is the promotion of subject-specific education and further education as well as the promotion of projects at universities, academic schools and vocational schools, which are characterised by the sustainable communication of innovative learning content in science and research. In total, thirteen sponsorship prizes were awarded in 2020. Due to the Corona crisis, the forum of TextilWirtschaft, which is normally the venue for the awards ceremony, unfortunately had to be cancelled in 2020.

Ein großer Erfolg war das 2. Fachgespräch Dialog in der Textilkette zu aktuellen PSA-Themen, zu dem WIRTEX, die Fachverbände IVGT e.V. und der GermanFashion Modeverband nach Frankfurt eingeladen hatten. Ein vielseitiges Programm bot Aktuelles von Trends im PSA-Design, über Normenfragen und Zertifizierungen bis hin zu Anforderungen im öffentlichen Beschaffungswesen.
Nach der Begrüßung durch WIRTEX-Geschäftsführer Dr. Andreas Marek eröffnete Sabine Anton-Katzenbach von der Textilberatung Hamburg die Vortragsreihe mit „Trends in der Persönlichen Schutzkleidung“. Dabei stellte sie fünf Trendthemen vor, die für die Entwicklungen in der Persönlichen Schutzkleidung von entscheidender Bedeutung sind: „Komfortgewinn“ durch elastische, leichte Fasermischungen und verschiedene Kleidungslagen, „Digitalisierung“ durch Smart-Textiles und Industrie 4.0, „Ende des Raubbaus“ durch Übernahme gesellschaftlicher Verantwortung, ein nach oben offener „Preis“ und „Normative Weiterentwicklung“ von Textilien und Pflegeprozessen.

Mehr als ein Jahr nach Veröffentlichung der neuen EU-PSA-Verordnung 2016 konnte Thomas Lange, stellvertretender Hauptgeschäftsführer im GermanFashion Modeverband, in dem auch die Hersteller von Arbeits-, Berufs- und Schutzbekleidung zusammengeschlossen sind, über aktuelle Probleme der PSA-Verordnung berichten. Er kommentierte Fragen mit weiterem Klärungsbedarf, die sich bei der Umsetzung der neuen Verordnung zeigen, gab wichtige Auslegungshinweise und erläuterte Urteile aus dem Produktsicherheits- und Produkthaftungsrecht. Auch Peter Heffels von der Berufsgenossenschaft der Bauwirtschaft befasste sich mit der Umstellung auf die PSA-Verordnung. Er setzte jedoch die Brille einer Zertifizierungsstelle auf und ermöglichte damit die Betrachtung dieser Thematik aus anderer Perspektive.
