Abstract: Eucalyptus (Eucalyptus camaldulensis) bark powder (un-irradiated and irradiated) has been used as natural colourant for dyeing un-irradiated and irradiated cotton fabric using different absorbed doses of Co-60 gamma irradiation to study the effect of radiation treatment on the colour strength of dyed fabrics. The data colour report is used for the evaluation of un-irradiated and irradiated dyed cotton using Spectra Flash (SF- 650) in CIE Lab system. Pre- and post-mordanting has also been carried out using chrome alum, potassium dichromate, copper sulphate, ferrous sulphate and stannous chloride as mordants. It is found that gamma irradiation has a potential to improve the fastness properties such as washing, light and rubbing of cotton dyed with Eucalyptus powder.
