From the Sector

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.

Exhibitors from eight countries have already confirmed to participate in the fair’s European Zone. They join an expected 500-plus total exhibitors from around the world. The 2018 edition of this biennial fair takes place from 4 – 6 September in halls N1 – N3 of the Shanghai New International Expo Centre.

While China retains its edge in terms of technical textiles and nonwovens production capabilities, in the eyes of Chinese buyers, European suppliers are still the leaders when it comes to technology and innovation. This was widely reported by European exhibitors at the previous edition in 2016 of Asia’s leading biennial trade event for the industry: Cinte Techtextil China.

“In the Chinese market, buyers want good quality products, so overseas companies, and products with recognised quality certifications, have a lot of potential,” Ms Ping Chen, General Manager of IBENA Shanghai Technical Textiles commented. “As a leading German company in the industry, our products are welcomed by many buyers at this fair. It is also important to be in the German Pavilion as this signals to buyers that we have quality products, and it attracts more attention.” Swiss firm Sanitized AG had the same experience. “As a Swiss company in the European Zone I believe it’s an advantage, as some local buyers have more confidence towards imported products,” Mr Steven Liu, Sales Manager said.

Other exhibitors commented on the long-term trends in the Chinese market. “There’s a definite shift to more high-quality machinery in China that isn’t affected by what’s happening in the overall economy. Moreover, there are opportunities for overseas suppliers as there is still a gap between us and what Chinese companies produce,” Dr Joachim Binnig, Vice President, Head of Development & Technology, Autefa Solutions Germany GmbH explained.

Mr Roger Zhang, Sales Manager for German firm J.H. Ziegler Nonwovens and New Materials commented: “Our products are mainly for high-end Chinese customers, such as BMW and Audi. The Chinese market has gradually matured, but the production capability for high-performance products which are energy efficient and eco-friendly is still developing, so there is a lot of space for overseas brands to develop here.”
