Today, textiles are used for more than just clothes or bags – they are high tech materials for high-tech applications. High-tech textiles must fulfill a number of functions and meet many requirements. That is why the Fraunhofer Institute for Silicate Research ISC dedicated some major developing work to this most intriguing research area. The result can now be seen at Techtextil trade show in Frankfurt from 4 to 7 May. On display will be novel textile-integrated sensors, a unique multifunctional coating system for textiles and fibers, and textile processing of glass, carbon, and ceramics fibers to fiber preforms.
Thin materials and new kinds of sensors now make it possible to integrate silicone elastomer sensors in textiles. They are suitable for applications in medical devices, sports equipment or even furniture and automotive parts, without interfering with the base material or the user.

For example, a special stocking was designed for diabetics so they can monitor the pressure load on their feet while walking. The in-stocking sensors provide three-dimensional pressure readings and will warn the wearer whenever the pressure builds up too high at just one spot.
The Fraunhofer ISC pressure sensors are combined with the wireless electronics unit developed by the Fraunhofer Institute for Integrated Circuits IIS and the technology provided by the Zentrum für Telematik ZfT so that readings can be transmitted to smartphones or tablets for easy monitoring. So far, a three-dimensional pressure measurement with comparably high number of sensors, good comfort and reduced costs is not yet available on the market.
In addition to active sensor functions, the call is on for equipment with additional passive functions. In order to provide textiles with other functions than just mechanical strength, they must undergo different refinement processes. Up to now, multiple coatings with different coating systems had to be used to provide a product with more than just one function, and the selection of property improvements was limited.
At Techtextil, the Fraunhofer ISC now presents the novel coating system »InnoSolTEX®« which enables the combination of up to six functions in just one processing strep. Several partners teamed up with the Fraunhofer ISC to jointly realize the new refinement solution »InnoSolTEX®«: The Saxonian Textile Research Institute STFI (STFI), the T_O_P Oberflächen GmbH and industry partners Schneider Textilveredlung GmbH, Alterfil Nähfaden GmbH and ROWO Coating Gesellschaft für Beschichtung mbH. »InnoSolTEX®« is based on ORMOCER®s, a class of environment-friendly materials developed at the Fraunhofer ISC.
The properties of ORMOCER®s can easily and precisely be controlled to meet given requirements. The water-based coating system allows to provide textiles with hydrophobic, abrasion resistant, flame retardant, antimicrobial, antistatic and washproof properties, in any combination. So, the textile industry is now provided with a finishing system of modular design which can integrate up to six functions in one single coating to meet manifold requirements. The coating can be equally applied onto threads or web fabrics.
Apart from textile integrated pressure sensors and textile finishing with ORMOCER®s the processing of textile fibers into two and even three-dimensional structures with new technologies becomes more and more important. The innovative production processes can be applied to inorganic fibers to create new applications.
On the Techtextil fair show the Fraunhofer Center for High Temperature Materials and Design HTL and the Application Center for Textile Fiber Ceramics present their projects and services for the development of ceramic fiber composites. Their work involves all stages of processing, from the base fibers to the final CMC components, so that both material manufacturers and material users are addressed. Moreover the Application Center investigates, tests and processes ceramic fibers with a view to different questions, and provides training and seminars on textile processing methods as well.
You can find the Fraunhofer HTL and Applied Center at the booth F23 of Bayern Innovativ in exhibiton hall 3.1. The Fraunhofer ISC with the topics textile integrated sensors and textile coatings is at booth E29 in exhibition hall 6.1, Messe Frankfurt, Germany.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
