Laser Welding
Laser
welding technology uses the energy of lasers to heat up the material and join them together. It is not often used in apparel production. The prerequisite for this technology is also to use thermoplastic synthetic materials. This technology is in the development phase and requires further research and development.
One of the leading laser technology developers who are working on laser-welded textiles is Leister Technologies AG based in Switzerland. They work with IR laser systems. Here the optical characteristics of the textile material in the invisible spectral range are relevant. Both an IR-absorbing and a non-IR-absorbing textile material are needed to create seams of high quality. Working with 2 non-IR-absorbing fabrics is possible as well. However, an IR absorber applied either by means of inkjet printing or manually is in part required in this case. Furthermore, the two thermoplastic materials being welded have to be the same. This means PET only joins reliably with PET, PP only with PP, and so on. Leister has done well with PA6.
