    摘要: The object of the invention is an additive for paper making by means of which the dusting tendency of paper can be reduced. The agent is based on starch, the molecular size of which has been reduced, and which has been cationized to a charge of less than 1.5 meq/g with a quaternary nitrogen compound. The agent is added to the fiber pulp for paper making prior to web formation.

    摘要: The invention relates to a method for reducing the amount of interference substances in the water circulations of processes involving wood-based fibre suspensions by binding the disturbance substances to the fibres by means of cationic starch. The amount of the said starch added to the fibre suspension is approximately 0.04-0.5% of the fibre weight.
