Victor B. Kuznetsov Doctor of Technical Science, Director of Research Institute for Textile Chemistry Fundamental Problems “IVNITI” The field of the research includes the following trends: theoretical bases of fabrics ablution after dyeing and printing; artistic and dyeing design improvement methods. The investigations are aimed to mathematical description and physicochemical study of hydrodynamic phenomena during textile materials ablution in aqueous or water-organic media regarding to solvation and solubility effects; application of physicochemical methods of influence on textile materials and dyes for improving artistic and dyeing design of the fabrics because of imparting to them special effects. The interrelation of colorimetric and photometric characteristics of dyed material under the change of dye state in fibers has been determined. Physicochemical mechanism of alkalis, acids and oxidizing agents action on fibers of various nature have been studied in order to obtain special effects on the fabric.
