Background and Aim

Despite enormous benefits of UV radiation, it is a threat to human health. Clothing is major equipment to protect. Although cotton fabrics are mainly used due to their excellent properties, they can pass the UV radiation. So, the modification of them is a significant to overcome this problem. Nanotechnology has an important role in this line. So, the aim of this study is investigation of ZnO nanoparticle size effect on UV-protection for nano-cotton fabrics.

Method

This study was conducted based on Cochrane systematic review guideline. Main databases such as PubMed, Scopus and Web of science databases were searched for achieving to relevant articles. The search strategy was completed with main search terms of “ultraviolet protection factor (UPF)”, “Textile”, “Fabric” combined with the terms of “Nanostructures” and “nanomaterials”. Preferred Reporting Items for Overviews of Reviews (PRIOR) was used as a method for analyzing the articles. After data extraction, by using of Minitab software version 21.1.0, detecting and removing of outlier's data was done by outlier boxplot at a 95% confidence level. Also, the Kolmogorov-Smirnov test was used for normality. Fit Regression Model was predicted to describe the relationship between size and UPF. At the end, the Monte Carlo simulation was applied by using Crystal Ball software. According to wavelength 310nm is responsible for the peak of the erythema and redness susceptibility of the skin, the particle size calculated via the formula proposed by Brus et al and appropriate UFP for fabrics was simulated.

Results

317 article were firstly achieved. Because ZnO can almost completely absorb the harmful UV wavelengths, relevant articles to ZnO were selected. After applying PRIOR and considering the limitations, 45 studies were regarded as appropriate, until January 30, 2022. The results showed that smaller particles provide the least transmission of UV radiation and therefore provide the highest UV-protection. Fit Regression Model was predicted as follows; "UPF=80-0.059size" for nanoparticles whose size ranges from 3.11 to 897 nano-meters. So, the highest UPF was 79.8 (Excellent protection) for nano-cotton fabrics. Mont Carol simulation showed that with more than a 50% certainty (53.71%), UPF is the ranges between 72.1 to 73.19. Therefore, if we use an approximately size of 3 nm for modification of fabrics, we can achieve a UPF rating of 79.8 at a wavelength of 310 nm.

Conclusion

Computational estimates show that the size of nanoparticles plays an important role in the estimating UPF value. Therefore, by optimizing the particle size in the synthesis process, the highest level of UPF value can be achieved. Moreover, the results of this study can help to develop experimental studies and achieve better results.
