FIELD: paper manufacturing.
SUBSTANCE: invention provides a composition for increasing the strength of paper, which includes a dialdehyde-modified polyacrylamide strength agent, a water-soluble compound containing one or more hydroxyl or amide moieties, and water. The water-soluble compound has a solubility in water of approximately 5 wt.% or more at 25°C and is contained in the composition in a mass amount that exceeds the mass amount of the strength-imparting agent.
EFFECT: proposed invention makes it possible to increase the strength of paper in dry and wet conditions.
