摘要：
The object of the invention is a method for manufacturing in a foam medium a sheet of paper or non-woven. In the invention, the surfactant used to form the foam is a nonionic compound of an ethoxylated alcohol of the Formula I:R--(OCH.sub.2 CH.sub.2).sub.n --OH (I)wherein n is an integer from 2 to 22 and R is a linear or branched alkyl group having 6 to 20 carbon atoms or where R is in the form of R'--X wherein X is an aromatic nucleus and R' is a linear or branched alkyl group having 2 to 16 carbon atoms. In particular, the invention applies to making household papers such as paper towels.
