Аннотация:The textile materials with polymeric coatings bearing rareearth element conjugates of variable color spectrum are obtained.The polymer basis in use is a new polyorganosilazane, which, onthe one hand, features high adhesion to the material fibers and, onthe other hand, hampers the hydrolysis of the REE conjugatesduring storage of the textile materials. It is shown that theduration of luminescent glow of the coatings on the surface of thetextile materials reaches 8 h at the REE conjugate content in themranging from 6 to 26 mmol.
