FIBROUS SHEET DISINTEGRATING IN WATER, PROCESS FOR MANUFACTURING SAID FIBROUS SHEET, USE OF SAID FIBROUS SHEET FOR THE MANUFACTURE OF A CORE

摘要

The invention relates to a fibrous sheet having a basis weight of between 20 and 1000 g/m2 being manufactured according to a wet papermaking process, and disintegrating in water in less than 120 seconds, said fibrous sheet comprising 10 to 70% starch and at least 30% of papermaking fibres on the basis of the total weight of the dry fibrous sheet. The sheet is used for instance for the manufacture of a water disintegrable core in a roll of tissue paper.
