LASER PLASTIC WELDING Laser Textile Welding

Basic principle laser transmission welding Laser radiation Joining pressure Most synthetic fibers in textile industry are made out of thermoplastic polymers and can be welded therefore. In laser transmission welding of thermoplastics a part transparent to the laser and one absorbing are joined together. The laser beam penetrates through the transparent material and impinges on the absorbing material, which melts due to the absorbed laser energy. By the applied external clamping force the transparent material is in physical contact with the absorbing one and melts as well. The polymer melts mix...
