Abstract:
The use of photoprotection products is indispensable today, due to the potential harmful effects of ultraviolet (UV) rays. Textiles are a natural barrier against UV radiation and can be made more effective by applying UV blockers. The present study investigates the photoprotection properties arising from dyeing cotton fabric with pomegranate peel extract. The extract was characterized by TPC, TFC, THT, color, pH, HPLC-UV and including its antiradical activity. The dyed fabric samples were evaluated for color, color fastness to light, rubbing, washing and sweating, along with a determination of SEM, EDS, ATR-FTIR, and UPF properties. The chemical analyses of the P. granatum peel aqueous extract by HPLC-UV indicated the presence of ellagic acid, punicalagin and punicalin derivatives. The extract showed antiradical activity (11.1 ± 0.4 CI50 (mg L− 1) which is consistent with a high amount of total phenols 307 ± 26 (mg GAE/g extract), total flavonoids 150.3 ± 2.3 (mg RE/g extract), and condensed tannins 632.6 ± 84.1 (mg TAE/g extract). The dyed fabric samples showed yellowish colors and good.
