As part of the research project ´Absorber systems for the laser welding of textiles´, scientists at the Hohenstein Institute (Bonnigheim) and the DWI Leibnitz Institute for Interactive Materials (Aachen) have developed new absorber systems for laser welding technical textiles in the infrared spectrum. The researchers have already used them to weld all kinds of different textile materials.
With the results of their research, the scientists have overcome one of the main challenges of laser welding: only a few textiles absorb laser radiation in the near-infrared light spectrum and are therefore intrinsically suitable for laser welding. To join other textiles successfully, you have to apply absorber materials to the proposed locations of the seams which absorb the near-infrared light.
