The article in the textile research journal presents a very useful and thought-provoking subject. The increasing amount of infiltration of UV radiations onto the earth’s atmosphere caused by the ozone layer depletion have made it imperative to adopt preventive as well as protective measures. This study has been conducted with a precise and clear objective to calculate the ultraviolet protection factor (UPF) of the dyed fabrics and establish its importance as a protective covering. A set of organic compounds assumed to act as efficient UV absorbers previously have been opted as the elements of research. This assumption is validated by the fact that these compounds have been tested and have reported to demonstrate favorable outputs. But, since all of these UV absorbers are complex organic compounds the selection range can be considered as narrow.
A holistic research has been carried out on these compounds and their respective UPF and light fastness levels have been determined. Also, their structural formulae as well as the exact chemical composition in terms of carbon, nitrogen and hydrogen have been shown that facilitates understanding. The hypothesis is supported by a series of elaborate experiments and the results have been analyzed and explained in detail. The results are measurable and offer a good statistical base to the experimental results. Also, the reasons for variations and undulations in the data obtained from the experiments have been justified but in quite a broad sense. For instance, the reasons for higher UPF value detected in the case of 4c and 4d compared to that in the case of 4a have been attributed to halogen substitution. However, measurement of the absorption abilities of these compounds has been carried out only on the basis of UPF and light-fastness. Furthermore, there is no discussion on the intermolecular dynamics of these organic compounds under consideration. The accuracy and error rates of UPF calculation as well as the experiments are also missing making it difficult to assess the actual efficiency levels. Data obtained from the experiments adequately establishes the truth of many of the statements made in the introduction such as the effect of additives, UV absorbers, presence of cellulose on UPF. However, the positive impact of sulphonic acid group has only been introduced but not proved and left as a matter of mere possibility to be simply believed on. The conclusion summarizes the objective of the research and the final results obtained from the experiments.
In a nutshell, the article revolves around a very useful research which has the potential to attract everybody, especially the industrialists, environmentalists and the government. The results provide ample evidences in support of the hypothesis and generate belief. In future, it would be advisable to research more on the issue and develop simpler and easy to manufacture compounds with similar properties.
