| Abstract [eng] |
The thesis analyzes the work of researchers from different countries, demonstrating their intensive search for new possibilities in recycling and reusing textile waste. Therefore, this thesis presents relevant research in this context, aiming to provide new functional properties to waste fibers of various types and nonwovens made from textile waste with unknown exact fiber composition, through chemical modification. The rapid pace of technological development in recent decades has resulted in a significant increase in the number of electrical devices, leading to a fundamental change in the extent of electromagnetic radiation in the human body. The relevance of this problem is evident through numerous published scientific papers that explore the development of new materials capable of partially or fully suppressing the effects of electromagnetic fields. Copper selenide is a p-type semiconductor material that has been extensively studied for the deposition of films on glass surfaces. However, a literature review did not yield any research on coating textile materials with copper selenide. Hence, this study investigates the modification of waste textile fibers of various types and nonwovens with different fiber compositions using copper selenides. Specifically, the cyclic sorption-diffusion method under selected uniform conditions was employed to coat the surface of the structural elements of these materials with CuxSe crystals throughout the entire volume of the material. In this thesis, nine fibers of different types and seven nonwovens with various fiber compositions from textile waste were modified with copper selenides. |
