    Abstract: A roll of wiping paper is obtained by winding a sheet of multi-ply absorbent paper around a core. The sheet includes at least a first and a second ply of absorbent paper, each with a grammage of between 15 and 30 g/m2 and at least one of the plies incorporating a wet strength additive. The thickness of the sheet Ep being between 0.02 and 0.07 cm, the diameter of the core being less than 3.5 cm, the diameter of the roll being between 4.5 cm and 11 cm for a volume V of absorbent paper per unit length of the roll, and the absorbency A of the sheet in cm3 of water per gram of paper being greater than 6 cm3/g. The ratio E=A/(Ep*V) of the roll is greater than or equal to 3.2.

    Abstract: The invention relates to a substantially rectangular multi-ply disintegratable absorbent sheet based on tissue which comprises at least three plies, and which has a coefficient KNOVE=RSM×RST×A×G×Exp(12×(E+Ep))×(1/Exp (SP))>75 000 where RST=strength in the cross direction of the sheet, in N/m RSM=strength in the machine direction of the sheet, in N/m G=basis weight of the sheet in kg/m2 E=thickness of the sheet in mm Sp=flexibility of the sheet in N A=absorption of the sheet in kg/m2 EP=mean thickness of one ply of the sheet in mm, EP being greater than 0.115 mm. The invention is also aimed at the process for manufacturing such a sheet and at rolls consisting of said sheets.

    Abstract: An embossed sheet is composed of at least a first and a second ply of creped tissue having a basis weight between 12 and 30 g/m2 according to which the first ply has a first embossed pattern composed of a series of first aligned protrusions of frustoconical overall shape, the tops of which are oriented towards the inside of the sheet, and the second ply has a first and a second series of protrusions, the tops of which are oriented towards the inside of the sheet, the second series having a height greater than that of the first series of protrusions. The protrusions of the first ply and the highest protrusions of the second ply are nested inside one another, and the lowest protrusions of the second ply are arranged between the protrusions of the first ply so as to create empty spaces between the two plies and promote a rapid absorption of liquid.
