SEPARABLE MULTI-PLY ABSORBENT SHEET, ASSOCIATED ROLL AND MANUFACTURING METHOD

摘要

The invention relates to an approximately rectangular, separable multi-ply absorbent sheet based on cellulose wadding that includes at least three plies and that has a coefficient K_NOVE = R_SM X R_ST X A X G X Exp (12 x (E + E_p)) x (1/Exp (Sp)) > 75 000 where; R_ST = strength across the width of the sheet in N/m; R_SM = strength along the length of the sheet in N/m; G = grammage 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 E_p = average thickness of one ply of the sheet in mm, where E_P is greater than 0.115 mm. The invention also relates to the method of manufacturing such a sheet, and rolls composed of said sheets.
