Light Reflection of Cu-sputtering-coated Cotton Fabrics and Effect of Sputtering Time, Acetone Pre- treatment and Fabric Structure

Abstract- The present research aims to vary the additional value on natural textiles by adding new properties with metal nano-scale coatings and evaluate magnetron sputtering coating technology suitability for natural textile coating. The paper describes the process of magnetron sputtering of copper coatings on six types of cotton textile materials. The analysis of the metal coated textile surface was carried out by scanning electron microscope and using a non-contact optical method. The method was based on the measurement of the difference of uncoated and coated fabric surface reflection mechanisms that allow getting a detailed insight in the textile surface changes after metal coating and during its exploitation. The research results demonstrate, that non-contact optical method can be applied to trace the changes of the textile surface relief, texture, trim after metal coating, as well to trace changes in coating evenness and deposited copper amount after exploitation process without the destruction of samples
