From the Sector

Together with the Johann Jacob Rieter Foundation, the Rieter Group is supporting a new Endowed Professorship for Industrial Artificial Intelligence (AI) at the ZHAW School of Engineering. The Professorship is dedicated to teaching and research in the field of industrial applications of Artificial Intelligence and will be announced later this year.

The new Endowed Professorship will be established at the Center for Artificial Intelligence (CAI) of the ZHAW in Winterthur. It will focus, in particular, on the application of machine learning methods and knowledge-based systems in connection with processes in production and service.

For Rieter, the commitment is related to the implementation of its technology leadership strategy. The contribution of the Johann Jacob Rieter Foundation to sponsoring the Professorship is in line with the Winterthur Cluster Initiative. The increasing digitalization of production processes opens up new perspectives for Winterthur as a business location.

Building Expertise in the Field of Industrial AI
The Endowed Professorship will serve to build expertise in the field of Industrial AI and will oversee a group that will focus on teaching and research pertaining to trustworthy machine learning. This involves, for example, the deployment of artificial intelligence with the aim of optimizing production processes in relation to the use of raw materials and energy, and making expert knowledge more readily available.

In addition to research, for the purpose of knowledge transfer, the new professorship will also be active in teaching, in the bachelor's degree programs in Computer Science and in Data Science, in the Master of Science in Engineering, and in continuing education.

The annual commitment of CHF 300 000 over a period of six years will be financed equally by the Rieter Group and the Johann Jacob Rieter Foundation.
“The use of artificial intelligence in industry is becoming increasingly important, especially with regard to the potential of data for evaluation and control of complex processes. The support of the Johann Jacob Rieter Foundation and the Rieter Group will allow us to further expand AI research in the field of industrial applications,” explains Prof. Dr. Dirk Wilhelm, Director of the ZHAW School of Engineering.

“The use of Artificial Intelligence will make a significant contribution to automation and process optimization, and thereby advance sustainability in the textile industry. This makes it an important element of the leading technology that Rieter offers,” emphasizes Rieter CEO Dr. Norbert Klapper.

“The Smart Machines cluster is growing in importance,” says Thomas Anwander, member of the Foundation Board, and adds: “The Endowed Professorship for Industrial AI at the ZHAW aims to promote Winterthur as a technology location by pooling locally available strengths in mechanical engineering and Industry 4.0.”

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.
