SURFACE DEGRADATION OF LINEN TEXTILES INDUCED BY LASER TREATMENT: COMPARISON WITH ELECTRON BEAM AND HEAT SOURCE

Abstract

Surface degradation of linen fabric induced by laser treatment with the aim of reproducing an image was investigated and compared with the degradation induced by an electron beam and a heat source. The results confirm that the brown shades obtained by the laser beam are mainly due to surface tar formation, and that the degradation pattern is similar to that observed by treatment with an electron beam. Surface thermal treatment, however, showed different fibre behaviour.
