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. Spectroscopy discusses the interaction between materials and electromagnetic waves. Spectroscopy results provide the information about the amount of emitted or absorbed energy of samples. It is one way of detecting unknown components of a material. Two subcategories of spectroscopy are atomic and molecular. The latter one is used in the present project, since the case studies are fabrics. Using cotton-polyestere 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 werw considered constant so that the effect of metal in fabrics structure could be investigated better. Owing to some problems in preparing weaving machines, the use of metals i.e. copper and aluminum in warp direction was not feasible. Spectrophotometer, Jasco V-570, with its accessory, ARN-475, was applied to measure the amount of absorbed rays in ultraviolet region. The accessory part is nessary when the spectroscopy of solid samples is to be determined. 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. statistical software was utilized to determine the level of comparison significance. Two ANOVA and DUNCAN statistical tests were applied to make the comparisons meaningful.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 copper samples in comparison to aluminum ones. But experimental results showed that copper had no significant effect on ultraviolet protection factor of woven fabrics composed of cotton-polyester. Conversly 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 denoted, nylon 6 fabrics with copper metal as their wefts accounted for better ultraviolet protection. But the contrary situation was tue for cotton-polyester fabrics. As experimental results depicted, the project wish to produce protective textile was fulfilled employing copper in nylon 6 fabric structure.
