The market in technical textiles has been a growth market for years and includes many niche segments related to individual applications. Every day sees the constant emergence of new groups of products thanks to tailor-made fibres, new processing technologies and ultra-modern textile machinery.
Because of the increasing importance of technical textiles, there is now a huge need for technology, quality and precision in the production of fibres, yarns, wovens and nonwovens as a first stage in the textile manufacturing process. The development of new high-tech fibres and the need to process them with care require all sorts of things from flexible re-structuring of the production process to user-friendly working procedures. That places high demands on both researchers and engineers.
The challenge of the efficient use of energy and resources The efficient use of energy, materials and resources continues to be the current major topic in textile machinery development and manufacture. Effective energy management increases competitiveness! So more and more textile manufacturers are undertaking checks of their input streams and processes with regard to energy efficiency and sustainability. Suppliers of manufacturing technologies will be showcasing large numbers of solutions to these issues at this year's Techtextil (24 to 26 May 2011), the international trade fair for technical textiles and nonwovens. The Business Units of Oerlikon Textile, for example, offer comprehensive all-round solutions in the field of textile machinery and plant construction and are constantly setting new standards for global textile production with their innovations. Accordingly, research and development play an important role in the company, which, for years, has ploughed back into it more than seven per cent of its revenues. One consequence of this is the energy-efficiency programme 'e-save' which stands out because of the exceptionally sparing use of resources in its production processes.
Oerlikon Neumag offers the world's largest portfolio of technology for the production of nonwovens. Nonwoven fabrics are attached mechanically by means of needles, which move vertically in and out of the fabric. Then the machine moves the fabric forward and the needles drop down once again. This process seals the fibres into the cloth. Up until now, the needles have been arranged manually, based on values derived from experience. With the help of a new kind of software tool, the geometry of the needle penetration can be simulated and the needle patterns optimised. That way, for instance, the stiffness and elasticity of the nonwoven fabric can be controlled. Recently, Oerlikon Neumag Austria have built numerous new needle beds on the basis of the software results (Techtextil, Hall 3, Stand A01).
