FIELD: textiles, paper.
SUBSTANCE: method of manufacturing paper resistant to moisture and dirt comprises processing of the porous paper web on both sides with the composition based on an aqueous dispersion of polymers, imparting to paper resistance to moisture and dirt, removing the excess of aqueous dispersion from the porous paper web, and drying. Processing of the porous paper web with the said aqueous dispersion is carried out in an impregnating bath. Removing the excess of aqueous dispersion from the web is carried out by passing the impregnated web between the squeezing press shafts, on the surface of which the coating is preliminary applied, comprising telomers obtained by free-radical polymerization of tetrafluoroethylene.
EFFECT: obtaining of paper with increased moisture resistance and dirt resistance.
