Development and research of textile materials with UV protection

The article presents data on the development of technology for imparting UV-protective properties to cotton fabrics at the stages of final finishing. Increase of functionality of textile materials is provided at the expense of introduction of highly effective methods of processing with use of textile auxiliary substances possessing UV-absorbing properties, and also application of new chemical and physical methods of intensification of proceeding processes. Technological solutions for processing cotton fabrics aimed at achieving the required level of physical and mechanical characteristics and resistance to UV radiation have been developed. The optimal parameters of preparation of working solutions were selected: concentrations of UV stabilizers, ratio of components, temperature and duration of treatment. The qualitative characteristics of the treated fabric, including the uniformity of the protective layer application and UV-protection efficiency, as well as physical and mechanical parameters were investigated. Both periodic and continuous treatment methods are proposed, providing stable fixation of functional substances on the surface of textile fibers. Implementation of the developed technology will improve the quality of finished textile materials due to simultaneous improvement of hygienic and protective properties, reduction of energy consumption and processing time. The results of the research can be used in the creation of modern technological processes for the production of textiles from natural, chemical fibers and their mixtures with specified functional characteristics, including for products of special, medical and everyday use.
