Transition to digital models of garments is the first step in dig-itization of the light industry. Adequate digital models can be obtained by using precise parameters of stress-strain properties of a fabric and other materials. The study has revealed regression dependences of the stiffness index of the polymer – fibre composite on the stiffness of the suit fabric and the combination of fusible interlining parameters. The obtained equa-tions can be used to design composite materials of the required stiffness, depending on the form of clothing being created

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.

The aim of the study was to improve the range of adhesive interlining materials for clothes to add to the product a complex of improved consumer (shape stability, wear resistance) and special (protective, health-improving) properties. We have found that the modification of the adhesive coating of interlining materials with oligoacrylates provides a transition from the traditional discrete 2D glue interlayers between the bonded materials formation to the highly branched 3D structures of the interfacial layer of composites creation. Using dynamic light scattering method, IR spectroscopy, differential scanning calorimetry, gas adsorption, optical and scanning probe microscopy, methods of textile materials science, we have identified technological approaches that ensure the polymer coating penetration into the intrafiber nanopore spaces of the textile layers. We have identified ways to control the elastic-deformation properties of composites in the modifying the adhesive interlining material process in order to design its properties for the requirements of various garment models. We found a unique possibility of using graftable oligoacrylate dispersion to stabilize the nanodispersed state of functional fillers (silica, nanoferrites) and increase the uniformity of their distribution in the composite structure.
