Abstract:
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.
Abstract:
The invention relates to a core intended to act as a support for a reel of paper, particularly of toilet paper, said core being formed by winding at least one strip of cellulose wadding, said strip being at least locally impregnated with starch so as to improve its rigidity. Configured in this way, the invention is capable of providing a core that has both the mechanical strength needed for the envisaged use and a friability that is vastly improved over a cardboard core so that it can be disposed of directly into a toilet bowl without the risk of blocking the waste pipe.
