Wireless power transmission for technical textiles

© Fraunhofer ENAS

The trend towards the "Internet of Everything" is ongoing. Whether in industrial, medical or everyday applications, more and more electrical devices are connected to each other, record sensing values, exchange data and react to them. Due to smaller structures, new processing possibilities and new flexible materials, such systems are also being used more and more frequently in the textile sector. For example, medical measurements can be recorded directly on a garment, actuators such as EMS electrodes can be integrated directly into the textile or functions such as MP3 players, GPS receivers, fall detectors, heating structures and much more can be embedded simply and intuitively in textiles. Communication and data exchange usually take place wirelessly via WLAN, Bluetooth, RFID or, in the future, via the 5G network.
Electrical energy is required for such applications and functions. Despite the efforts to further minimize the energy demand of electronic circuits, it is not always possible to operate these systems completely energy autonomously. Therefore, energy storage devices such as batteries or rechargeable accumulators are necessary for operation.

Environmentally friendly Chitosan: Insects supply chitin as a raw material for the textile industry

© Fraunhofer IGB

Fossil-based chemicals are often used in textile processing. That is why the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is researching sustainable biobased alternatives. The Institute is working on utilizing side streams from the animal feed manufacture for the production of chitosan. The biopolymer is supposed to be used as a sizing agent in the processing of yarns or for the functionalization of textiles.

Simulating and optimizing industrial spinning process

Spinning polymer filaments, for example for personal care products, is highly complex: simulating the process involved is too much for currently available computing power to handle. Fraunhofer researchers have successfully applied new approaches to simplify te calculations necessary for simulation. Now for the first time complete spinning processes can be simulated, providing a better understanding of the processes and greatly simplifying their optimization.

Machine Learning in Textile Industry

© Fraunhofer ITWM

Dramatic changes are taking place in the demands placed on the textile industry. The trend is towards individualization in many areas, similar to car purchasing, for example. Consumers are increasingly demanding tailor-made products. This change in consumer behaviour is lucrative for European textile companies, since the customer-specific manufacture of products with small batch sizes leads to a relocation of production back to Europe. However, this requires the digitization of production, which the Fraunhofer Institute for Industrial Mathematics (ITWM) supports with hybrid simulation-based Machine Learning (ML) methods.

Simulation of fibers, knitted and warp-knitted fabrics - mathematics in technical textiles

The High Performance Center Simulation and Software Based Innovation hosted the Industrial Workshop Digital Technologies for Fibers, Nonwovens and Technical Textiles at the Fraunhofer Center. For two days, it offered experts from industrial development and application-oriented research the opportunity for practical exchange.

Recent developments such as the coupling of simulation techniques for the computer-aided investigation of the effects of the manufacturing process on the product properties were in the foreground. An equally important goal of the workshop was to focus on the views of experts from industry. This was achieved by interesting presentations from representatives of leading companies in the field of nonwovens and technical textiles such as BJS Ceramics, BSN medical, Sandler, OLU-Preg Composite Group, Oskar Dilo Maschinenfabrik or MANN+HUMMEL.
