Main tasks of presented research are to impact the additional value on natural textiles by adding to them 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. Analysis of the metal coated textile surface realized by scanning electron microscope and using non-contact optical method based on the difference of uncoated and coated fabric surface reflection mechanisms that lend to get a detailed insight to the textile surface changes after it’s coating by metal and during it’s exploitation. The investigation results evince, that non-contact optical method measurements of reflected light intensity can be applied to trace the changes of the coated fabric surface without samples destruction.
