On the occasion of its 125th anniversary, the VDMA has put together a series of multimedia reports. Published on the new website https://humans-machines-progress.com the reports show: Machines are not an end in itself for the machinery engineering industry. Regina Brückner, Vice-Chairperson of the VDMA Textile Machinery Association and Managing Associate of Brückner Trockentechnik, explains: “Machines are the means to make progress come true for people and to meet challenges like energy, mobility, infrastructure and health. Textiles and textile machinery play – sometimes hidden – a major role in improving daily life.”
Textile machinery is, for example, a starting point for resource-efficient construction. Lightweight construction materials based on knitted, woven or nonwovens fabrics enable enormous savings potential in aerospace. 1,974 litres of kerosene can be saved per aircraft per year with 20 kg less weight on the A320.
Infrastructure maintenance is currently time consuming and costly because the reinforced concrete that has been used in many structures, contains steel reinforcing bar that can corrode, making the concrete structure crack. Textiles offer a robust alternative by replacing steel with carbon. Carbon concrete is durable and versatile in its uses. The carbon used to reinforce concrete is even stronger than steel, but at the same time much lighter and more durable since it does not corrode. Building elements made of carbon concrete can thus be thinner, reducing demand for raw materials and, as a result, energy use and CO2 emissions are cut almost by half. These materials that help maintaining bridges and buildings are made on warp knitting machines, where yarn is processed into net-like cores or even three-dimensional spacer fabrics.
In medical technology, textiles play a vital part, too. The use of textile-based implants, such as stents, heart valve replacements and artificial cartilages or tissues, is growing strongly in modern surgical techniques. Garments with integrated sensors are already commercially available, including T-shirts that can measure pulse, breathing and body movement.
In the working world, textiles are both ubiquitous and practically invisible: Even in modern production sites, workers need professional and protective clothing to protect them from injury and safeguard against hazardous environments. Air conditioning is meanwhile becoming widespread in the modern working world – even in regions with no weather extremes. Air and dust filters made of nonwovens are most of the time not visible but they are there and help to protect staff, as well as sensitive equipment, in production plants.
