Comparison ofUVProtection Properties of Cotton Fabrics Treated with Aqueous and Methanolic Extracts ofAchyranthes asperaandAlhagi maurorumPlants

Abstract

UV radiations are high-energy radiations present in sunlight that can damage human skin. Protection against these radiations becomes vital especially in those areas of the globe where UV index is quite high that makes the inhabitants more prone to dangerous effects of UV radiations. Clothing materials are good blockers of UV radiations, particularly when the fabric cover factor is high and/or the fabrics contain suitable UV-blocking finishes. In this study, effect of application of aqueous and methanolic extracts of two different plants, i.e., Achyranthes aspera and Alhagi maurorum on UV protection properties of cotton fabric was investigated. The results showed that the fabric samples treated with extracts of both the plants have excellent UV protection properties as indicated by their ultraviolet protection factor. It was concluded that both the aqueous and methanolic plant extracts are very effective in blocking UVA and UVB radiations, when applied on cotton fabrics. The UV protection performance of Achyranthes aspera extracts was much better as compared to that of Alhagi maurorum, and methanolic extracts of both the plants outperformed the aqueous extracts in terms of UV protection.

Comparison of UV protection properties of cotton fabrics treated with aqueous and methanolic extracts of Solanum nigrum and Amaranthus viridis plants

“…In our previous work, we successfully achieved excellent UV protection on fabric by treating it with colorless plant extracts rich in flavonoids and phenolic contents . Current research is also a continuation of the same concept.…”

“…In our previous work, we successfully achieved excellent UV protection on fabric by treating it with colorless plant extracts rich in flavonoids and phenolic contents. 41 Current research is also a continuation of the same concept. In this work, Amaranthus virdis and Solanum nigram were selected from 12 plants subjected to screening tests for identification of phenolic and flavonoid contents.…”

A review of UV radiation protection on humans by textiles and clothing

“…The British Standards institute has also developed a standard for evaluating the photo-protection by children clothing. However, the standards developed for evaluation of UV protection of textiles mostly focus on Protection from UV radiation through clothing unstretched dry fabric, which is not the situation in practical wearing (Morison, 2003;Saleem et al, 2019;Nazir et al, 2016).…”

Optimizing the Salt-Processing Parameters of Achyranthes bidentata and Their Correlation with Anti-Osteoarthritis Effect

“…The chemical constituents of A. bidentata include oleanolic acid glycosides, saponins, ecdysterone, ketosteroids, and flavonoids [6]. Although modern pharmacological studies have shown that A.bidentata has a plethora of bio-activities, including anti-osteoarthritis [7], improving memory [8], regulating blood sugar level [9], preventing apoptosis [10], promoting angiogenesis, UV protection [11], anti-convulsion [12], anti-osteoporosis [13], improving xerophthalmia [14], and alleviating acute kidney injury [15], this herb is commonly used in the clinical treatment of osteoarthritis. After being salt-processed, the effects will be dramatically enhanced.…”
