摘要
The model of structure formed by randomly arranged crossed fibres is proposed. The model makes it possible to calculate the number of contacts between the fibers and to estimate the mechanical characteristics of a structure, provided that contact adhesion forces are known. Within the framework of this model, experimental data obtained by the author and his coworkers on the forces of adhesion and friction between individual cellulose fibers as well on macroscopic rheological parameters of aqueous suspensions of these fibers, including those obtained in the presence of surface-active additives such as poly(ethylenimine) and tetraalkylammonium halides are analyzed.
