A modern technique for a controlled surface modification of synthetic fibres consists of irradiation with a pulsed UV laser, which can be used to execute submicrometre surface treatment on polymers. Many types of synthetic fibres, e.g. poly(ethylene terephthalate), polyamides and aramides, show a characteristic surface modification when irradiated by ArF and KrF lasers. The originally smooth surface of these fibres changes its morphology to a rather regular roll‐like structure perpendicular to the fibre axis after this treatment. A phenomenological report on the dependence of structure formation on polymer and laser conditions is given. © 1997 SCI.
