FIELD: chemistry.
SUBSTANCE: invention relates to organic fibres having a mineralised surface, which includes organic fibres having a length in the millimetre range, the surface of which is at least partially coated with finely dispersed nanoparticles alkali-earth metal carbonates using binding materials based on copolymers which contain, as monomers, one or more dicarboxylic acids or one or more monomers from a group of diamines, triamines, dialkanolamines or trialkanolamines, and epichlorohydrin, a method of producing such organic fibres having a mineralised surface, aqueous suspensions thereof, use thereof in paper production, in finishing paper surfaces, plastic surfaces, cement and clay, in paint and lacquer, and use of binding substances according to the present invention to coat organic fibres with nanoparticles of alkali metal carbonates.
EFFECT: providing fibre-pigment or filler composites, as well as aqueous suspensions thereof, which not only have good optical properties and good printing properties, but also have an insignificant or no tendency to segregate in treatment conditions thereof, and also enable to obtain paper or cardboard having high content of filler of nanoparticles which are otherwise hard to hold due to their fineness.
