<p>The invention relates to methods for using laser beams in monofilaments made of plastic material. For example, in a method for connecting extruded plastic monofilaments along their surface area, monofilaments with different absorption coefficients for laser beams (LS) are used, which are contacted along their surface area at least in certain sections and which are melted together by penetration of the laser beams in the contact area. In order to optically mark extruded monofilaments or individual monofilaments of a monofilament assembly, at least the monofilament that is to be marked is extruded by adding additives which can react with color change under the effect of the laser and the corresponding areas for the desired marking are then treated with laser beams. In order to structurally modify monofilaments of individual monofilaments of a monofilament assembly, the monofilament that is to be structurally modified is extruded with laser beam absorbing additives and subsequently treated with laser beams.</p> |
