To mark this year’s 125th anniversary, the VDMA has put together a series of multimedia reports on a new website – – in which the major topics facing the world today, including work, energy, health, urbanization and materials, are examined.

“Since the beginning of time, humans have longed to take their future into their own hands,” says Thomas Waldmann, managing director of the VDMA Textile Machinery Association, “and since then, humans have been designing, building and using machines for this purpose. Humans, machines and progress are thus intrinsically linked. Humans use machines to improve the lives of all on this planet, but what are the biggest challenges facing mankind and what contribution are machines and mechanical engineers already making today to solve them?

“Throughout the year, we will publish more reports on the major challenges of our time. What will work look like in the future and what roles will robots play in it? How will energy be used tomorrow? These are a few of the questions we will seek to address.”

Future health

The textiles manufactured on modern textile machinery have a major role to play in addressing many modern challenges.

In fighting disease, for example, advanced textiles impregnated with insect-repellents are vital in regions where malaria poses a risk, while protective clothing is used is vital in the fight against all arising contagious epidemics.

The use of textile-based implants such as stents, heart valve replacements and artificial cartilage or tissue is also growing strongly in modern surgical techniques and materials are also getting smarter.

“Intelligent textiles can now heat up, be luminescent, generate energy and communicate,” says Waldmann. “Garments with integrated sensors are already commercially available, including shirts that can measure pulse, breathing and body movement, heatable underwear, heatable jackets with communication and lighting systems. There are even inlay soles with GPS tracking devices or smart shoes that can be opened up, closed or heated up using an app, while also counting steps and calculating calorie consumption. Smart textiles are already very useful in the medical field, whether for the preventive monitoring of breathing and heart rate or for keeping track of wound healing processes.”

Energy savings

As reinforcements for composites, textiles perhaps have an even bigger role to play in meeting the demand for more efficient transport, infrastructure and energy.

Enormous savings potential in aerospace have triggered major developments in lightweight construction, where along with aluminium and titanium, fibre-reinforced plastics are the dominant lightweight construction materials, based on knitted, woven or nonwovens fabrics.

An increasing proportion of carbon fibre reinforced plastic (CFRP) is incorporated in wide-bodied aircrafts such as the Airbus A380 and the Boeing 787 Dreamliner. About 25 per cent of the overall structure of the A380 consists of CFRP and the proportion in the Airbus A350 XWB is to be increased to more than 50 per cent.

Fibre reinforced composite also now play an important role in automotive construction. In its development of the i3 and i8 electric and hybrid vehicles, BMW has used CFRP and developed a passenger compartment in series production for the first time. Mechanical and plant engineering companies played a significant role in the process development and automation of the production steps. The boundaries of what is feasible have been continuously pushed and important lessons have been learned for the future use of fibre composites.

Better buildings

Carbon fibre-reinforced concrete, recently developed in Germany, will be another important material in maintaining buildings, bridges and towers going forward.

“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 building material crack,” explains VDMA publicity officer Nicholai Strauch. “Textiles offer a robust alternative by replacing the steel with carbon. Carbon concrete is durable, environmentally friendly 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 in half.”

Rapid changes

Work, of course, is changing too, as a result of digitisation and Industry 4.0, and both textile machinery builders and their fabric manufacturing customers can expect rapidly-changing environment in the next decade or so, as a result of Industry 4.0.

Robotics are increasingly replacing hard, repetitive and unhealthy manual labour, but more than ever, we will need human expertise in respect of both production and customer requirements,” says Strauch. “History has shown that every revolution in production and every new level of automation has ultimately created more new and higher-value jobs.

“In modern production sites, workers also need professional and protective clothing to protect them from injury and safeguard against hazardous environment. Air conditioning is meanwhile becoming more and more widespread in the modern working world – even in regions with no weather extremes. Air and dust filters made of nonwovens are already playing an essential role in protecting workers, as well as sensitive equipment, in production plants.”

Around 120 of the most important manufacturers of textile machinery and accessories from all sectors of the trade are affiliated within the VDMA Textile Machinery Association and exhibit regularly at ITMA. Collectively, they are responsible for annual sales of around €3.4 million, the lion’s share of which is achieved via exports.
