When using lightweight fabrics of costume-dress assortment for manufacture of clothes, the most challenging problem is to correlate changes in properties of shell fabric and fusible interlining during its transformation from flat to volumetric state. Developed the reinforced interlining materials capable of forming in conjunction with the shell fabric composites, possessing optimum shaping characteristics. They are easily shaped, and after a final wet-heat treatment they obtain required rigidity and elasticity values, thus ensuring that volumetric shape of a garment will be preserved in the process of wearing it by a user. The technology realizes original methods of selecting precision values for elastic-deformation properties in the laminate of shell fabric and an interlining by forming in a duplicating cloth 3D self-organizing structures of a reinforcing polymer-fibrous composite. It was proved that there is a chemical interaction between acrylate copolymers and polyamide adhesive, discretely distributed on the surface of interlinings. This ensures the formation of a three-dimensional reinforcing structures of a unique bristle-like shape, encrusting the surface of the fibers and penetrating into their nanoporous system. The required values for elastic-deformation properties of polymer-fibrous composite materials for various kinds of textile carriers can be found by changing topology of applying polymeric modifiers and conditions of copolymerization. A wide range of variation in elastic-deformation properties makes it possible to adapt quickly the assortment of interlining materials to the individual customer requirements taking into consideration the purpose of the manufactured clothing and characteristics of the shell materials.
