Abstract (en)
[origin: WO9833982A2] The invention relates to the use of an aqueous sizing dispersion containing a cellulose-reactive sizing agent and a hydrophobically modified dispersing agent for sizing cellulosic fibres by addition of the sizing dispersion to a stock containing cellulosic fibres, and optional fillers, and dewatering the stock on a wire to obtain a web containing cellulosic fibres, wherein the stock has a cationic demand of at least 50 mu eq/litre stock filtrate. The invention further relates to an aqueous dispersion containing a cellulose-reactive sizing agent and an anionic hydrophobically modified cellulose-derivative, its preparation and use in the production of paper. The invention also relates to a substantially water-free composition containing a cellulose-reactive sizing agent and an anionic hydrophobically modified cellulose-derivative, its preparation and use in the preparation of an aqueous dispersion of cellulose-reactive sizing agent.
