Abstract
Methods for the use of laser beams in the case of plastic monofilaments are proposed. For the optical marking of extruded monofilaments or individual monofilaments of a monofilament union, at least the monofilament to be marked, accompanied by the addition of additives reacting with a color change under laser action, are extruded and treated with laser beams in the areas corresponding to the desired marking.
