Polyamide (nylon 6) fabrics were irradiated with 193 nm ArF Excimer Laser and then dyed with commercially available acid, disperse and reactive dyes. The morphology of the irradiated surfaces was examined by scanning electron microscopy (SEM). Chemical surface changes of the materials were characterized by X-ray photoelectron spectroscopy (XPS) and change in crystallinity was examined by differential scanning calorimetry (DSC). Polyamide materials irradiated with laser developed ripple-like structures of micron size on the surface. These structures are strictly perpendicular to the stress direction of the fiber. It is worth noting that the dyeing properties of all dyes on polyamide fabrics changed remarkably after the treatment. The change in color is believed to be closely related with the appearance of ripple-like structures. Changes in chemical properties of the treated materials may also be one of the reasons for dyeability changes. This work suggests that the dyeing properties of disperse and reactive dyes on nylon can be improved after laser modification.
