and a greater stitch length of the warp-knitting yarns increase the drapability and complicate at the same time the handling of the material. In this case, drapability is defined as the adaptation of laminar semi-finished material on curved three-dimensional surfaces without structural folds. Aiming at a serial production of preforms for the automotive industry a locally adjusted formability will ease the required automated production processes. In order to adjust the stitch type locally an electro-mechanical driven guide bar was integrated into a warp-knitting machine with multiaxial weft insertion. Furthermore the yarn run-in and therefore the yarn tension can be varied from stitch course to stitch course with a computer controlled beam control. Due to these technologies, non-crimp fabrics with locally adapted drapability - from stitch course to stitch course - can be produced.

In addition they show great advantages in comparison to artificial valves made of metal or plastic available on the market. They are distinguished by a reduced risk of rejection and thrombus. Furthermore, they are supposed to regenerate and to grow. Latter is especially important regarding the therapy of infants as they may outgrow the standard valves.

Currently the standard thermoplastic powders for selective laser sintering are based on polyamide 12 precipitated from a solution. This leads to restrictions for many applications and thus research on other polymers with enhanced and product related properties plays a major role for applying selective laser sintering to serial production of individual components. In this demonstrator the attempt to produce polymer powders by the conversion of man-made fibres is shown. Different methods of cutting semi- crystalline filament yarns could be realized. This is the first step to use more Page 2/2
materials within the laser sintering. The monopole of only polyamide 12 for technical sinter products is therefore banned and new products out of commodity polymers can be used.

A textile based conductive system allocates electric power supply. Active lighting components, like light-emitting diodes are placed into textile composite structures. Various LEDs with different light intensities are used. A specific conductive technology enables a reversible bonding between the illuminating components and the textile material. Insulation is solved by the use of a membrane. Functional and design lighting make the product interesting for active sportswear. Thus safety aspects can be implemented, for example the bicyclist can be seen in the dark. Furthermore functional aspects can be realized by using individual parts for an additional light source.

UMIC – Development of a wireless network for continuous and mobile health monitoring The UMIC research cluster was founded to develop a next generation high-speed mobile communication network. As part of this cluster, suitable application scenarios are explored and developed. Medical health care is one of the key scenarios. The HealthNet Vision scenario, involves several multi-disciplinary research institutes from textile technology, computer science to medical engineering. The HealthNet Vision describes a near- future patient-oriented network that connects the patients with medical professionals. This kind of homecare scenario is necessary to keep overall health care costs affordable and is therefore actively investigated by research groups around the world. Key feature is a wireless sensor network that obtains the patients vital parameters (e.g. ECG, respiration rate, and temperature) via an energy- aware, event-driven network. Additionally, peer-to-peer technology is used Page 3/3
