Abstract
Currently, the main objective of many investment programs for the development of pulp and paper enterprises is both to reduce the level of environmental pollution and to improve the quality of products, including at enterprises that have introduced elements of the best available technologies. Analysis of the results of numerous studies shows that the effectiveness of cellulose technologies for chemical processing and for paper production, as well as the high level and stability of the quality of artificial fibers, paper and cardboard products can be achieved only if the specifics of the processes of structure formation in dispersed systems in which the dispersion medium is water are taken into account. The apparent dualism in the behavior of water was formed under the influence of different points of view on the nature of the bonds in the structure of cellulose fibers and products made from them. In the theoretical foundations of the physico-chemistry of polymers, water is assigned the role of a plasticizer, and in the fundamentals of physico-chemical mechanics, water is considered as a coagulant in a dispersed system. The article discusses the state and prospects of applying the theoretical views of scientific schools of polymer physics and chemistry and physico-chemical mechanics of dispersed systems in the modernization of the pulp and paper and textile industries.
