发明名称 METHOD OF PREPARATION OF A CELLULOSIC PULP, CELLULOSIC PULP TO BE USED IN ABSORBENT PRODUCTS, AND SUCH ABSORBENT PRODUCT
摘要 The invention relates to preparation of cellulosic pulp capable of being defibrated (fluffed) for the manufacture of an absorbent material intended to be incorporated as a component in absorbent products. The invention is characterized therein that a stock of cellulosic fibres in aqueous suspension is pH-adjusted to 4<pH<8, that at least any water-soluble, non-polymeric aluminium salt is added to the stock, said salt in aqueous solution at said pH forming at least any hydrocomplex with aluminium of the type A1(OH)n x, where n is a number between 1 and 3, and x is 0, + or 2+, that said salt in aqueous solution is caused to act on the cellulosic fibres in said suspension at said pH during a period of time of at least 2min, and that the fibre pulp thereafter is formed to a web, which is dewatered and dried. The invention also relates to the prepared cellulose pulp as such and to its use in absorbent products.
