Abstract: A core intended to support a reel of paper, particularly toilet paper, is formed by winding at least one web of cellulose wadding. The core is formed by winding at least one web of cellulose wadding having at least 0.51 g of water-soluble material per gram of cellulose wadding, the water-soluble material being designed to make the web of cellulose wadding more rigid and easier to disintegrate. Thus configured, the core that has both mechanical strength fit for the intended purpose and is far easier to disintegrate than a core mad of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.

Abstract: A fibrous sheet having a basis weight of between 20 and 1000 g/m2 that disintegrates in water, has 10% to 70% starch on the basis of the total weight of the dry fibrous sheet. The disintegration time in water, measured in accordance with standard NF Q34-020 applied to a specimen of the sheet of 9×8 cm2, is less than 50 seconds. A loss of strength of the sheet measured in accordance with a defined table test corresponds to a loss of strength of a specimen of said sheet forming an angle of at least 85° after having being wetted with water for a duration of 6 seconds, and/or a residual wet strength of the sheet relative to its dry strength, as measured according to a defined ring crush test, is less than 1%. The fibrous sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.

Abstract: 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, has 10 to 70% starch and at least 30% of papermaking fibers on the basis of the total weight of the dry fibrous sheet. The sheet may be used for the manufacture of a water disintegrable core in a roll of tissue paper.
