Textiles can be used for heating, cooling and lighting. They can measure the heart rate, as well as monitor soil erosion on slopes, and can even be launched into space for use as space reflectors – as long as they are electrically conductive.
The electrical conductivity of warp-knitted textiles is the subject of extensive development work at KARL MAYER. In this project, entitled “textile-circuit”, multibarraschel machines are used with and without a jacquard facility to incorporate conductive yarns directly into the textile during manufacture.
The first results are now available and show what can be achieved, including the use of textiles for remote control.
The original control tool and its production principles were both successfully shown at the IDTechExShow in Santa Clara and at the Aachen-Dresden-Denkendorf International Textile Conference, both of which were held in November 2018.
The pattern provides electrical conductivity. Electrically conductive structures with a virtually unlimited range of designs can be produced on multibarraschel machines. This is possible, thanks to multibar patterning using Karl Mayer’s innovative string bar system, with which the yarns can be positioned individually and as required onto a ground – following the principles of tailored fiber placement. The ground can be produced with a wide variety of different designs, and jacquard patterns can also be worked, depending on the type of machine.
