FIELD: textiles, paper.
SUBSTANCE: invention relates to pulp and paper industry and relates to a method and system of use of starches with a low content of fatty acids in the sizing composition for paper, to inhibit the precipitation of multivalent salts of fatty acids. The method of inhibiting the precipitation of multivalent saturated fatty acids on the equipment and/or devices for sizing of paper consists in using the composition for sizing the paper surface, containing elevated levels of starch solids for sizing the surface, and the source of polyvalent cations, such as drying salt of multivalent metal, by including (wholly or partially) one or more starches with low content of fatty acids for sizing the surface in the composition for sizing the paper surface.
EFFECT: invention provides a sized paper having improved properties.
