发明名称 Sizing process.
摘要 A method of sizing cellulosic fibres materials for the formation of sheet products, e.g. paper, is carried out at a pH of 6-10 using a sizing agent and a cationic material, which is a powdered aluminium compound (preferably the hydroxide) on whose surface is a substance which is cationic at pH 6-10. The invention allows the use of rosin-based sizes at neutral-alkaline pHs and results in a paper with better aging and ink acceptance properties.
