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.

• This Spring Summer Season 2018 Graciela Huam's second knit collection takes us to the Gray Beach…

Northern Europe is known for its short summer, the cool wind during the morning and evening and its unpredictable climate. Those countries are not warm even during the summer season.

Therefore, many people often travel to the south: Spain, Italy, Portugal or Asia longing for sun, sand and sea. And there is Lima, a coastal city with a good climate and a characteristic grey sky throughout the year, where the sun is hidden among the dense clouds, but despite this detail, its strong presence is still felt. If we move to Lima, we lie on the sand and cast our gaze to the sky as it teleports us to the cold northern European sky with the difference that our presence is on that warm gray beach.

Graciela Huam takes its heritage and inspiration from The Netherlands and Peru, those are the countries that influence and guide her work. The designer combines the vibrant Peruvian culture with the Dutch avant-garde design and her favorite colours are powered by the landscapes of both.

The products are designed in the Netherlands and created in the Andes of Peru, using only the most exclusive Peruvian materials such as the luxurious Alpaca and the famous Pima Cotton. All garments are made by passionate and skilled Peruvian craftspeople. This results in beautiful and high quality garments and a contemporary, prêt-à-porter style, creating versatile collections of knitwear.

Graciela Huam follows the principles of responsible and sustainable production, using traditional methods in order to achieve quality that is superior to industrially made products.

The brand is committed to partnering with local entrepreneur artisans and is working in association with a group certified with the principles of fair trade. Knitwear will always be a good investment and just like a work of art can create a truly iconic end result.

The choice of fabrics and production of Graciela Huam's knitted garments combined with this unique technique will reveal to you the high dedication and passion the designer feels for her work.
