| Techtextil and Avantex Symposiums for the entire sector  Techtextil, International Trade Fair for Technical Textiles and Nonwovens, is the communication platform where specialists obtain comprehensive and new insights into state-of-the-art developments in the fields of technical textiles and textile technologies. In particular, the wide-ranging programmes of lectures of the Techtextil and Avantex Symposiums – at which numerous top speakers present market-ready research results or discuss tomorrow's research projects – are 'input generators' for the entire sector. The symposiums will be held at Congress Centre Messe Frankfurt on all three days of Techtextil, from 24 to 26 May 2011.The wide range of lectures covers, inter alia, the results of intensive research on the subject of "Virtual Examination of the Geometry and Permeability of Fabrics for Filtration". In this connection, the lecture by Jakob Barth, Kaiserslautern University of Technology, Germany, will focus on the demands placed on woven filtration and protective textiles in everyday use. The properties required of the textile are a specific combination of particle restraint, permeability to liquid or gas and resistance to wear. Today, the parameters for the design (type of yarn, fabric density) and the production (weave) of a woven fabric are generally set on an experimental basis. Kaiserslautern University of Technology is currently researching into ways to show the behaviour of real fabrics on the basis of virtual fabrics. William Blackwood, Dow Corning, Midland, USA, will discuss, "Relating the characteristics of silicone to the properties of coated fabrics" against the background of the unique range of properties of silicone that no other plastic has achieved to date. As the global market leader in the fields of innovative silicones and silicone-based technology, Dow Corning offers over 7,000 products and services. 'Insecta' is a product line made by Devan, Ghent, Belgium, with which textiles can be coated to repel insects. After three years of intensive research, this technology, which is based on environmentally friendly materials, is now ready to be marketed. The research results will be presented by Alain Langerock in a lecture entitled "Insecta: An innovative and sustainable solution for insect control management". Fibre-reinforced plastics have the advantage of being very light yet strong and stress-resistant. However, low thermal conductivity limits their use. In electrical appliances, for example, heat cannot be dissipated, which could result in damage to electrical components. Nevertheless, the heat and surface conductivity can be increased eight-fold through the use of special carbon fibres. The latest research results show that special yarn designs can achieve a conductivity of over 15 W/mK (thermal conductivity). Michael Glowania, ITA at RWTH Aachen, Germany, will talk about this phenomenon in his presentation on "Carbon fibre-reinforced plastics with increased thermal conductivity". The separation of multiple emulsions is important to split oil and other organic components from waste water and to remove water from petroleum and kerosene. Multiple emulsions contain very small droplets, which calls for the use of very fine filter media with diverse nano-coatings to produce different levels of wettability on the surfaces of the individual fibres. It has been shown that the quality of emulsion separation in the case of oil-water emulsions is particularly influenced by three factors – pore size, porosity and different interfacial energies. "Nanoparticles coated filter media for effective separation of secondary emulsions" is the title of the lecture by Swarna Bansal, ITV Denkendorf, Germany. High-performance textiles with nano-technology is the theme of the lecture by Prof. Jesse S. Jur of North Carolina State University, USA, on metal oxide coatings for surface modification of textile fibres. Dr. Helga Thomas, DWI of RWTH Aachen e. V., Germany, will report on a research project focusing on the generation of polypropylene nano-fibres by melt electro-spinning for the development of new high-performance filters on the basis of nano-scale pulp. In his lecture, Dr. Volkmar von Arnim, also from ITV Denkendorf, Germany, will discuss polythiophene-based nano-particulate antistatic textile finishes with high wash fastness in conjunction with electrically conductive nano-particles and linkage systems. write your comments about the article :: © 2011 Construction News :: home page |
