The chemical surface composition accompanying UV‐laser induced surface structuring of fibrous materials such as poly(ethylene terephthalate) (PETP) is discussed. Only a few real chemical changes have been investigated up to now (formation of carboxylic groups on PETP, formation of C=O bonds on polypropylene). Much more data exist on the formation of yellow layers on the laser‐treated samples, consisting of debris derived from the ablation process. Analysis by laser desorption mass spectroscopy (LD‐MS) and XPS confirm the composition of those layers as highly carbonaceous. Methods for using LD‐MS for fibre identification and methods for avoiding debris‐layer formation are described together with some surface grafting experiments. In some cases excimer irradiation may be used to remove fabrication agents from polymer surfaces. © 1998 SCI.
