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.
