The physicochemical foundations of surface phenomena and dispersed systems are outlined. Examples of the manifestation of surface phenomena and the use of dispersed systems in the production of textile materials and their refining are given.

The textbook is intended for students studying in the areas of “Technology and design of textile products”, “Technology of light industry products”, “Chemistry” , “Chemical technology.”

Surface phenomena Surface tension and adsorption. Surface of condensed phases. interphase tension and adhesion. Interphase surface "solid - gas". Electrosurface properties. Adsorption from solutions on the surface of solid adsorbents. Disperse systems Theory of formation of colloidal systems. Properties of disperse systems and determination of particle size. Stability and coagulation of disperse systems. Fundamentals of physical and chemical mechanics dispersed systems. Solutions of high molecular weight compounds. Solutions of colloidal surfactants (lyophilic colloidal systems). Coarsely dispersed systems. Colloid chemistry and environmental problems. Dictionary of colloid chemical terms and definitions.
