A Comparison between UV Protection Factor of Fabrics composed of Aluminum and Copper

Radiation is energy emission in electromagnetic waves such as, Gamma, ultraviolet, visible, infrared or corpuscle. People are surrounded by things always emitting and absorbing radiative energy at the same time. The past decade has witnessed an alarming increase in the incidence of skin cancer worldwide because of ultraviolet radiation. Therefore protective textiles against ultraviolet radiation seem essential. This paper purpose is to compare the effect of Aluminum to that of Copper on UV protection factor. Using Cotton-Polyester and Nylon 6 as warps and Aluminum, Copper, Cotton-Polyester and Nylon 6 as wefts, six sample fabrics were woven and coded as Cotton-Polyester, Nylon 6, Cotton- Aluminum, Cotton-Copper, Nylon-Aluminum and Nylon-Copper. F44 and Smith were two machines with which samples were woven. Warp and weft density of fabrics were considered constant so that the effect of metal in fabrics structure could be investigated better. Cotton-Polyester and Nylon 6 fabrics were considered as main samples to which other fabrics composed of metal were compared. In other word, Nylon-Aluminum alongside Nylon-Copper and Cotton-Aluminum alongside Cotton-Copper were compared to Nylon 6 and Cotton-Polyester, respectively. Appling two ANOVA and DUNCAN in SPSS statistical software, the level of comparison significance was determined. Regarding the fact that Copper emissivity coefficient is higher than that of Aluminum, results were supposed to indicate more amount of electromagnetic waves absorption in all Copper samples in comparison to Aluminum ones. However, experimental results showed that Copper had no significant effect on ultraviolet protection factor of woven fabrics composed of Cotton-Polyester. By contrast, for Nylon 6, applying Aluminum metal didn’t cause any significant influence on improving ultraviolet protection factor. Mentioned results could be attributed to different cover factors of woven samples. As results showed, Nylon 6 fabrics with Copper metal as their wefts accounted for better ultraviolet protection
