| dc.description.abstract | The study was planned to assess the efficacy of pomegranate and onion peel extracts on cotton and silk fabrics with respect to microbial resistance. Pomegranate and onion peel extract in two concentrations i.e. 3g/l and 5g/l were prepared. Desized and scoured cotton and degummed silk fabric were finished with these two pure extracts of pomegranate and onion peels and their three standardized combinations by two methods i.e. exhaust and pad dry cure method. SEM analysis was also done for visual analysis of extract absorbed by the fabrics. To study the efficacy of pure pomegranate and onion peel extracts and their combinations, the finished samples were tested for microbial resistance activity quantitatively by AATCC-100 test method before and after washing. Physical properties were assessed before and after application of finish. Change in physical properties regarding fabric weight, thickness, air permeability, moisture regain, bending length, tensile strength, elongation and wicking property were assessed and effect of washing on all these properties was examined. It was found that percentage yield of extract was 17.27% for pomegranate peel and 7.46 % for onion peel. Three combinations i.e. 50:50, 25:75 and 75:25 were standardized and selected on the basis of their bacterial reduction from five different combinations of pomegranate and onion peel extracts i.e. 50:50, 25:75, 75:25, 35:65 and 65:35 for the research work. Bacterial reduction of cotton and silk finished fabric with pure pomegranate and onion peel extracts and their three combinations by exhaust method were found to be more effective bacterial reduction as compared to pad dry cure method. As the concentration of extracts increased, bacterial reduction of all finished samples also increased. Among all the treatments, cotton and silk fabric finished with combinations of 50:50 was found to be more effective against bacterial reduction as compared to other combinations i.e. 25:75 and 75:25 and pure pomegranate and onion peel extracts. It was 98.58% bacterial reduction in cotton fabric with 5g/l concentration of extract and 98.06 % bacterial reduction in silk fabric with 5g/l concentration. The efficacy of the finish was analyzed and found that cotton and silk fabrics finished with the 50:50 combination of extract of pomegranate and onion peels showed the maximum wash durability up to 5 washing cycle. Bacterial reduction was found to be more in both finished cotton and silk fabric with 50:50 combination of extract in 5g/l concentration after one washing cycle as compared to five wash cycles. The percent change in weight, thickness, bending length and elongation of all finished samples were increased after treatment. The increase in these physical properties of finished samples was found with increase in concentrations of extracts while air-permeability, moisture regain and tensile strength decreased. After washing, weight, thickness, bending length and tensile strength decreased whereas there was increase in air-permeability, moisture regain and elongation in all finished samples. Thus, 50:50 combinations of pomegranate and onion peel extracts with 5 g/l concentration applied by exhaust method exhibited excellent bacterial resistance. | en_US |
