The study was designed to apply and evaluate the colour fastness of natural dyes on cotton knitted fabric with references to four criteria, including colour fastness to washing, colour fastness to sweat, colour fastness to light, and colour fastness to rubbing. Test was carried out for 30min at 60o C and grading was done for color staining and color change by the respective grey scale. However, the rating of colour change was quite subpar; turmeric received the lowest score, and tea and henna

The Xenon Arc was used to conduct tests on colour fastness to light. Wet rub grade was 4, whereas Dry rub grade was 5. Rubbing fastness properties of these natural dyes were comparatively poor and the results of the grading for light fastness were very poor.
