Abstract

Conventional non-stationary artificial heating methods, such as infrared radiators, have various deficits: The heat fields are small, their range is short, and the installation options are limited. In addition, they are environmentally harmful due to high emissions. To make in- and outdoor areas usable at lower temperatures, an energy consumption-optimized heat transfer is required. In this work we are investigating on an innovative, intelligent, modular textile for indoor and outdoor use. The use of conductive wires, sensors and a data-driven control circuit in the textile enables targeted heat radiation, which can be expanded as required thanks to its modular design. This reduces emissions and precisely controls energy consumption. By developing a demonstrator, the concept of the layered structure of the textile module, including unidirectional radiation and sensor technology, is being investigated. The conductive wires are incorporated into a flexible carrier material using a modified embroidery machine. In the process, the carrier material must meet the previously defined design requirements that are based on the material investigation and preliminary tests on embroidery feasibility. The structure of the intelligent textile is constructed, realized as a prototype, and validated. Through the combination of a heat source and flexible support material, it is possible to bring a competitive product to the market.
