Abstract

Technical textiles market worldwide is forecast to grow by 4 per cent per annum between 2002 and 2010. As a result, by 2010 the technical textiles and industrial nonwovens sector will consume some 23.8 million tones of fibre – up from 16.7 million tones in 2000 and a value of US $ 90 billion – and have a value of US $ 126 billion. Knitted fabric production for technical textiles showed on overall growth of 34.5 per cent from 1995 to 2002 in Western Europe. Over the last decade knitted fabrics and products have been increasingly designed and developed for a very wide spectrum of technical applications, including automotive textiles, medical textiles, geotextiles, sportswear, safety and protective textiles and environmental protection textiles, just to name a few major growth areas of technical textiles. Warp and weft knitted spacer materials are being commercially developed for a very wide range of technical textile products, because of a number of unique design opportunities that they offer. Knitted spacer fabrics are a single
composite of at least three different substrates integrated together during the knitting process. Continue reading Knitted Three-Dimensional Structures for Technical Textiles Applications

The PASTA project: “Integrating Platform for Advanced Smart Textile Applications”

J. DE BAETS,
imec-CMST, Gent, Belgium

PASTA is a FP7 integrated project on integration of electronics into fabrics, with partners from 5 different countries. Until now, many developments in the smart textile field have been focusing on textile technologies (conductive wiring, sensors, connectors.) in a combination with classic printed circuits with classic components.

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.

Nanoscience goes Pret-a-Porter: Novel Nanogold-Wool-Composite Fibres

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.

Challenges for Combining Semiconductor (Thin Film) Technology with Textile Substrates towards Textiles for Energy Production

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.

Adaptive Textiles for the Home

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.
