The thesis is devoted to finding ways to improve the rationale and durability of leather clothes with a film coating is in operation or dry clean and systematization of scientific views and the development of a conceptual methodology and practical approach to its identification and merchandising expertise. For the accumulation and synthesis of a priori knowledge of the object of study selecting criteria for the identification and determination of the values of indicators of consumer properties of the object of investigation used systematic procedure and physic-mathematical methods. To simulate and optimize the properties of the inventive composition to restore the film coating on the skin for clothing used method Maclean-Andersen and desirability function. Identification of species of the polymer coating leather for clothing, as well as identification and merchandising expertise of the research object held by the developed methods of copyright. Investigated physical and mathematical properties of the films and restore film coating on the skin for clothing, formed composition modified alhycarboksienthonolatum mixture of synthetic fatty acids C7-C9 fraction, formed on the basis nitro varnishes NC-573 and the metal complex dye (azopolyhexamethyleneguanidine-beta-naftolsulfanyl acid cobalt chloride), which allows estimate the resistance of the coating operation and significantly improve the durability of the object of study. The mathematical modeling methods set the optimum formulated to restore the film coating on the skin for clothing at a ratio of ingredients: nitro varnishes NC-573 - 0,1825, MCC - 0,1825, ethylacetate - 0,5248, alcohol - 0,0852, synthetic fatty AKEA and fraction C7-C9 - 0,0250. The obtained based on the skin to clothing is resistant to weather and mechanical influences so that enhances its durability. First developed: methodological and practical bases merchandising expertise of the research object, based on the systematization of research results, and the accumulation of the new data on the skins for clothing, identification polymer film former in coating composition for natural lather its defects, digital and data bases on which an electronic toolkit as a component merchandising expertise to ensure the object of study and methodology for its merchandising expertise. The proposed user information content recommendations for the operation and maintenance of clothing made of leather, is the basis for developing a standard: "Leather clothing. Consumer Information. General requirements". Instructions symbols and improved care will ensure operation of leather clothes on purpose, its proper care, periodic restoration coating on the chemical cleaning, which is key to the life of the leather on purpose, thus increasing its durability. The research can be used by manufactures, consumers, the chemical cleaning solutions for the problem of improving the durability of leather clothes film-coated, and will enable consumers properly labeled, will reduce the burden on the environment by reducing the amount of materials used in dry cleaning.
