Abstract: The possibility of the simultaneous bleaching and anti-pilling of cotton fabric using UV radiation on hydrogen peroxide impregnated knitted samples was studied. The effect of a photoinitiator or sensitiser, sodium hydroxide as an activator, sodium silicate as a stabiliser for H2O2, and the irradiation time on the samples’ whiteness, yellowness, pilling rate and strength loss was investigated. Comparisons of the results with the conventional pad steam process indicate that adequate whiteness can be obtained, while keeping the strength loss within acceptable limits, by padding cotton fabric with pad-steam pad bath components under UV irradiation. In addition, the reduction in pilling tendency is comparable with Biopolished samples on an industrial scale.
