Indutech to present innovations for coating & optical inspection at Techtextil

With eleven product groups and twelve areas of application, Techtextil covers the world market for technical textiles and nonwovens in its entirety. With over 500 exhibitors, 'Indutech' is the biggest area of application at this year's Techtextil in Frankfurt am Main. 'Indutech' stands for the use of technical textiles in industrial and technical fields, e.g., for materials, testing systems and research, for new developments, progress and cooperation.

Two examples of innovations of this kind have been announced during the run-up to the International Trade Fair for Technical Textiles and Nonwovens from 16 to 18 June 2009. They are a new type of coating system, which will be presented by a young company, and new and improved inspection systems for quality assurance. Additionally, the initial results of a European nano-research project will be presented exclusively at Techtextil 2009.

Young company develops new coating system
Cordus GmbH from Mühlhausen will be taking part in Techtextil for the first time this year because the company was only founded in the spring of 2007. Since mid-2008, it has been making polymer and glass cord at its factory in Mühlhausen, Thuringia. “Our products are primarily used as reinforcing materials by the rubber industry”, explains Manfred Heine, Head of Purchasing and Sales. “They are used, for example, in power-transmission elements and hoses for industrial and automotive applications, as well as for paper-machine clothing.”

On the basis of their technical properties, the glass cords are used as reinforcement for toothed drive belts, especially in the automotive sector. When it comes to reinforcement applications, the company works closely together with universities, research institutes and industrial companies to develop surface-treatment technologies that, according to the manufacturer, are characterised by outstanding strength and adhesion, and permit the surface adhesion of the fibres to be optimised in relation to the rubber systems of the individual customers.

“In addition to the use of the established wet-coating process for surface coating, Cordus has developed a new coating method, the CCVD system, in which the cords are no longer subjected to the wet-coating process. Instead, the new method uses complex chemical processes that change the chemical structure of the surface of the cord so the finished product is distinguished not only by mechanical adhesion but also by a chemical valency generated by the rubber compounds in which it is embedded”, explains Heine.

Besides a significant improvement in the adhesive qualities offered by the CCVD process, Cordus is also working with partners from research and industry to develop an extremely strong, hydrolysis-resistant glass fibre that will set new standards for toothed drive belts for automobiles.

The 'MeshInspector' series: optical inspection system for quality assurance
OSIF GmbH fromGarbsen near Hannover celebrates the fifth anniversary of its founding this summer and will present the 'MeshInspector' series at Techtextil. For OSIF customers, quality assurance is an important aspect of their business. In this connection, Joachim Imiela, Head of Marketing and Sales, says, “Despite or because of the difficulties on the world market, quality assurance has gained significantly in importance for our customers since the middle of last year. With the aid of our systems, they can achieve a considerable improvement in the quality of the products supplied and thus set themselves apart from their competitors, something that is particularly important in the current difficult market situation.”

The 'MeshInspectorLine' measures mesh materials in a production machine. A high-resolution matrix camera views the material using transmitted light. It registers information such as mesh size and angle and makes an analysis of any defects in the material. Faults found are recorded and, according to the manufacturer, shown clearly on the monitor. Additionally, faulty areas can be marked on the material or the position of the fault notified to overlaying control systems.
