In the HOT lab we research textiles made of solid wood. The continuous filament made of solid wood is developed here. We design processing equipment for wood thread production and finishing and build dobby and jacquard weaving processes adapted to the wood thread with a weaving width of 80 cm and any length. The HOT Lab researches the interaction of design-forming influencing variables of the wood thread and wood thread fabrics. The interrelationships between the technical factors of production and processing as well as the technical and aesthetic functions of material and form are investigated. The HOT lab researches the occurrence of the raw material willow wood in Europe.
