Abstract: This paper reports a standardised method termed as Stain Degradation Assessment (SDA) method, developed for the quantitative evaluation of self-cleaning efficiency of the finished fabric. The method involves (i) a standardized staining procedure to apply a uniform stain on the fabric, (ii) instrumental evaluation of photodegradation of stain in terms of K/S using a template to reduce error, and (iii) analysis of K/S values to evaluate stain degradation in percentage and its comparison with visual assessment. This method has been found to give a reproducible and comparable assessment of stain degradation on the textile material with respect to UV exposure.
