Polyamide (nylon 6) fabrics were irradiated with a 193 nm argon fluoride excimer laser and the effects on the dyeing properties of the fabrics were studied. Chemical analysis indicated that carbonisation occurred in the laser-irradiated samples. The laser treatment breaks the long chain molecules of nylon, increasing the number of amine end-groups which change the dyeing properties of acid and disperse dyes. The results suggest that laser treatment could be used to improve the dyeing properties of nylon fabric with a disperse dye.
