Influence of dispersity of reinforcing polymer to the polymer-fiber composite materials’ rigidity

Abstract

Abstract This research aims at validation of the technological approaches to the provision of penetrating the polymer binder into the structure of the filament carrier in order to construct a developed interfacial layer in the form of molecular brushes. Brush “bristles”, enshrined by the outer end in the layer of the copolymer binder, can give elastic properties to the composite material obtained by duplicating the shell material with reinforced adhesive interlining materials. As a large part of the interlining materials range comprises a mixture of polyester fiber with cotton or viscose, the problem of accessibility of textile liner web for reinforcing polymer is originally considered in relation to the cellulosic component, which has a developed system of pore spaces. This work defines the technical possibility of regulating the elastic-deformation properties of the fused panels of garment by changing the degree of reinforcing polymer (RP) dispersion fineness, providing different terms for penetration into the structure of fiber material. To change the capacity of the RP to penetrate into the fiber structure a method of ultra-dispergation was used by the mechanical activation of hydrosols in a colloid mill. There is an experimental prove of the decisive role of the reinforcing polymer penetration into the pore spaces of the cellulose component of the interlining material for the formation the branched comb structure of interfacial layer, which provides a comprehensive improvement in the ability of materials to form the bulk shape of the garment and its preservation while distorting.
