• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

Implementing visions – with composite textiles by vombaur
As your development partner, vombaur facilitates innovative composites projects for challenging applications. In innovative and safety-sensitive industries such as automotive and aviation, chemical and plant engineering.  The composites experts at vombaur develop, create samples of and manufacture woven tapes and seamless round or shaped woven textiles by vombaur – in collaboration with the customer's enterprise development teams and individually for the respective projects. This is how novel and unique lightweight components made of high-performance textiles are created for visionary lightweight construction projects.

"Fibre-reinforced composites are the ideal material for future-oriented construction projects," explains Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "Their outstanding technical properties and design possibilities open up new and fascinating perspectives for construction projects. From building construction to civil engineering, from bridge construction to interior design. As an experienced development partner for sophisticated lightweight components, we at vombaur contribute our seamless solutions to these kinds of future-oriented projects."

WEIDMANN GmbH in Süßen is known worldwide as a specialist for the finishing of fiber and down-proof articles and woven industrial fabrics. Customers particularly appreciate the company's reliability and flexibility with regard to their individu-al requirements, and consistently high quality of its products. The Swabian textile manufacturer finishes premium fabrics, mainly for the bedding industry, using the latest technology and in an environmentally conscious manner.

The complex production and finishing processes for high-quality fabrics require a reliable and efficient machine technology. With this in mind, WEIDMANN has always relied on the proven stenter technolo-gy from BRÜCKNER. For many decades, the German textile machinery manufacturer has been a world leader in the con-struction of production lines for the finishing of classical textiles, woven industrial  fabrics, nonwovens, glass fabrics and floor coverings. In addition to stenters, the company's production program also in-cludes coating lines, relaxation dryers, sanfor lines, continuous dyeing lines as well as ovens for the bonding of nonwovens and other special lines. All machines are produced 100% in-house in Germany.

Both companies continuously invest in new and innovative technology in order to be successful and competitive today and in the future. Only Recently, a completely newly developed BRÜCKNER stenter was installed in the ultra-modern plant at WEIDMANN. During the intensive project engineering phase it soon became clear which features are of special importance for their daily production requirements:

• uniform moisture distribution in the machine entry and during pick-up of the specialized   chemicals in the finishing padder before the thermoprocess
• weft-straight fabric flow with minimized residual distortion
• very good accessibility for maintenance and daily cleaning
• sensor technology and automation of setting parameters for energy optimization
• heat-recovery with hot water generation for the dye house
• the line must be fully Industry 4.0 capable

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.
