The topic of sustainability and bioeconomy will be the focus of the ITA's presentation at the Techtextil from June 21-24, 2022 in Frankfurt/Germany. The Institut für Textiltechnik of RWTH Aachen University (ITA) will showcase the various research areas of the institute at the Elmatex joint stand with the following exhibits.
3D printing robot on textiles
The 3D printing robot is a mobile and size-independent 3D printer for large-area components on textiles. For the first time, a 2.5D support structure can be printed on a textile with such a printer.

Recycling rope
The recycled rope is a climbing rope that consists of 50% recycled rope production waste and is available on the market. It is an example of textile-to-textile recycling in PPE. The ITA has developed 100% recycled, high-strength filament yarns for the rope.
CO2 sock
The CO2 Sock is made of elastic TPU fibers, which are produced on the basis of CO2. This results in a reduction of the carbon footprint. ITA has developed a melt spinning process for this special polymer, which is currently being scaled up to industrial scale. By reusing carbon dioxide from industrial waste as a raw material for textile and clothing products, the carbon footprint is improved.
Teddy bear with scarf made from recycled acrylic waste
The teddy bear wears a knitted scarf around its neck that is made of 50% recycled waste from blanket production using PAN fibers. In addition, intermediate products from all process steps of the solvent-based reprocessing of the waste are used in the production of this knitted fabric.
Bioresorbable stent
The most common materials for wire-based vascular stents Nitinol or Elgiloy can cause long-term problems such as thrombosis and other complications. In contrast, bioresorbable stents can perform their structural function for the required time (e.g. a few months) and then be resorbed without causing adverse reactions in the patient.
Recycling Atelier
In addition, the new Recycling Atelier of the ITA Augsburg and the Augsburg University of Applied Sciences will be presented. The Recycling Atelier in Augsburg/Germany represents a center for research and development along the entire textile production chain for textile recycling and thus makes a decisive contribution to the transformation of the linear economy to the circular economy.
