FIELD: textile industry.
SUBSTANCE: filler is added into fibrous mass, and fibrous fabric is shaped from specified fibrous mass. Then fabric is dried on paper- or cardboard-making machine. Applied filler represents composite material, containing fibrils of cellulose or lignocellulose, onto which particles of light-scattering material are deposited. According to the present invention, filler is put in contact with dispersant prior to mixing with fibrous mass.
EFFECT: improved light-scattering properties of paper and cardboard without reduction in filler retentivity.
