Method for the manufacture of a paper or non-woven sheet in a foam medium. According to the invention, the surfactant used to form the foam is a non-ionic ethoxylated alcohol-type compound of general formula (I): R-(OCH2CH2)n-OH wherein n is an integer from 2 to 22; and R is a straight or branched alkyl grouping having from 6 to 20 carbon atoms, or R is of formula R'-X in which X is an aromatic ring and R' is a straight or branched alkyl grouping having from 2 to 16 carbon atoms. The invention is useful, in particular, for the manufacturing of all-purpose paper such as kitchen wipes.
