PROSYS-Laser is dedicated to developing highly innovative “passive”
and “active” laser-protective clothing and curtains, hardly available on the market today, for use with hand-held laser processing devices (HLD) and with automated laser machines. Key developments are: passive functional multi-layer technical textiles, providing a high level of laser resistance, active system incorporating functional multi-layer smart fabrics which detect laser exposure and, by means of safety control, deactivate the laser beam automatically and test methods and testing set-ups to qualify passive and active functional technical textiles and tailored PPE.

Professor J.H. Johnston and Dr. K.A. Lucas have recently developed a novel approach for dyeing merino wool with gold nanoparticles by coupling the surface plasmon resonance and the chemistry of gold with that of wool fibres. In a related approach presented here, the research is carried out in three major steps: (a) formation of gold nanoparticles, (b) preparation of wool surface for dyeing process and (c) fabrication of nanogold-wool-composite. The synthesis of red colloidal gold uses reducing agents such as tannic acid. Purple and blue nanogold forms in the presence of other reducing agents and/or surfactants.

In this paper we would like to discuss the challenges of direct fabrication of electronic components onto the textile substrate, e.g. preparing energy harvesting devices by coating on monofilament level or using base coatings. There is an increasing amount of research being done to realise this direct fabrication. This has several advantages over the traditional method where the components were stitched, laminated or fixed by some other means onto the textile. The fixation techniques usually show problems with interconnects, the components used were of the traditional kind, having a rather low flexibility and stretchability, resulting in a loss of the inherent properties of the textile substrate.

Continuous weavable multifunctional carbon nanotube yarns are fabricated at one-step by spinning from a catalytic chemical vapor deposition reaction. The CNT yarn is formed through the direct assembling of carbon nanotubes in the gas flow as continuous integrated by mechanical winding. Kilometers of high-quality continuous yarn are spun from this process through the design of the CVD reaction with innovative spinning methods.

This paper introduces a series of design-led investigations exploring the
conceptualisation and materialisation of adaptive textiles for the home.
As modernism engaged architecture in a redefinition of its boundaries by promoting values of transparency and efficiency, the home became an environment primarily conditioned by technology, more and more disconnected from the exterior. Today, as we realize the consequences of our ability to engineer the world, this paper is asking: can the design of self-actuated textiles contribute to a domestic culture in which technology cultivates a relationship of interconnectivity with nature. By presenting parallel explorations into the material prototyping of lightresponsive textiles and design probes into the materialisation of immersive textile environments based on electro-active polymers, the paper will discuss, beyond the purely functional, the cultural and poetic potential of smart technologies, including thin film photovoltaics, light-induced liquid-crystals and dielectric elastomers.

During the last decade, research on intelligent textile systems progressed steadily. Today, science is focussing on full integration of electronics into textiles. E-textiles function like their rigid electronic companions but keep their textile properties. To interconnect components within the system, textile structures need to be equipped with electro-conductive properties. For flexible solar cells or fibrous transistors, electro-conductive coatings are applied. Transistors, acting as electrical switches, are essential for realizing fully integrated intelligent textile systems. By electroless deposition of pyrrole and copper on polyester fibres, conductivity is achieved. A DC conductive gate electrode is designed.

As electronics become more abundant and fulfill an increasing role supporting our life with communication, sensing, etc. integration into our world in an unobtrusive way is necessary. Integration into materials which are surrounding us like textile or thin, foil based, conformable systems, which can even be worn to the body, are possible options. Foil materials are thin and compatible with technologies like printing, lasering and (organic) electronic functionalities like light generation (Light Emitting Diodes, OLEDS), detection (organic photodiodes, OPD) can be incorporated) or organic photovoltaic cells, OPV). Interconnection of these elements to textile or stretchable carriers in order to create a conformable system is challenging.
