Abstract (en)

[origin: US4632730A] Paper, especially wet- or dry-creped paper, is manufactured with a high rate of absorption of aqueous media by using carboxylic acid esters of carboxylic acids with 8 to 30 carbon atoms and at least one of ethoxylated and/or propoxylated primary and/or secondary alcohols with 12 to 40 C atoms, ethoxylated and/or propoxylated alkyl phenols, ethoxylated and/or propoxylated amines, and ethoxylated and/or propoxylated amides, with a degree of ethoxylation or propoxylation of 3 to 50; and/or by using polyethers obtained from the reaction of long-chain epoxides with 8 to 30 carbon atoms and at least one of ethoxylated and/or propoxylated primary and/or secondary alcohols with 12 to 40 C atoms, ethoxylated and/or propoxylated alkyl phenols, ethoxylated and/or propoxylated amines, and ethoxylated and/or propoxylated amides, with a degree of ethoxylation or propoxylation of 3 to 50.
