Use of the dispersion for binding particles of zeolite to fibers. Production of paper or paperboard by forming and dewatering a suspension of cellulosic fibers wherein dewatering is carried out in the presence of particles of a zeolite, the dispersion being added to the suspension prior to dewatering. Production of dry-laid paper, nonwoven or fluff pulp, in which cellulosic fibers are carried by a gas stream, in which the dispersion is sprayed onto the fibers while they are carried by the gas stream.
