The most difficult technological problem in the production of garments is the creation of the required complex geometric shape and ensuring its safety during operation. It is promising to carry out developments aimed at justi-fying methods for increasing the elastic-deformation properties of a garment package by forming three-dimensional self-organizing structures of a reinforced polymer-fiber composite (PFC) in the main material or a duplicating web. PFC is formed when a polymeric binder penetrates, as which polyacrylate, polyurethane and other dispersions can be used, into the interporous and nanopores space of the fibrous material. At the same time, the possibility of fine adjustment of the stiffness and elasticity parameters is provided by scientifically justified selection of components and application of complementary variants of nanoengineering of the interphase layer. An experimental estimation of the dispersion state of the prospective assortment of preparations as well as the effect of the dispersion degree of the binder on the basic elastic-deformation properties of PFC samples was carried out. It is established that the penetration of the reinforcing polymer component into the submicroscopic pores of the textile carrier is a techno-logically necessary condition for the organization of interfacial interaction in the structure of the composite material ensuring the provision of the cushioning material with the required set of functional properties: increasing rigidity while maintaining high resistance to crushing. The microlevel of the particle size of polymer dispersions determines the surface distribution of the reinforcing polymer with penetration into the inter-fiber spaces, which contributes to the formation of a rigid but brittle film that breaks down when a test crushing load is applied. An effective method of preliminary ultradispersing of reinforcing polymer dispersions is the use of cyclic rotor-pulsation influences with pauses of cooling the treated system to room temperature.
