An Investigation on Natural UV protective finishes on cotton fabrics

There is increasing interest in the many beneficial aspects of green tea and pomegranate to human such as anti-carcinogenic, antiaggregant, anti-allergic, anti-bacterial, anti-mutagenic and anti-oxidant activities. Besides these
beneficial aspects, it has been reported that green tea & pomegranate ingredients especially polyphenolic families (i.e., catechin), have some UV protection property both in vivo and topical applications. In this study cotton fabric was taken and it is treated with both green tea & pomegranate extracts in the presence of three different mordants like alum, tartaric acid & chitosan. The effect of phenolic moiety, i.e. catechin on both green tea & pomegranate was studied. From this investigation it is clearly evident that, the cotton fabric treated with green tea using alum as mordant shows significant improvement in the %UV radiations blocked compared with the cotton fabric treated with pomegranate.
