摘要： A method for forming a dispersible nonwoven substrate in an aqueous medium comprising, consisting of, or consisting essentially of contacting a fibrous substrate with an aqueous nonwoven binder comprising an emulsion polymer having a polydispersity index of at least 10, a weight average molecular weight of less than 1,000,000 and from 8 weight percent to 22 weight percent acid monomer, based on the weight of the emulsion polymer, is disclosed. The aqueous nonwoven binder can be prepared by a method comprising the steps of: a) emulsion polymerizing at least one mono-ethylenically unsaturated monomer and at least one acid monomer in an aqueous solution using an initiator wherein the initiator is present in the aqueous solution in an amount in the range of from 0.5 weight percent to 1.5 weight percent, based on the total weight of the monomers, to form the emulsion polymer; and b) neutralizing the emulsion polymer with a neutralizer selected from the group consisting of an amine having a pKb of 4 to 7, an alkali hydroxide, and combinations thereof to form the aqueous nonwoven binder. The dispersible nonwoven substrates can be used to produce dispersible wipes, such as baby wipes, personal care wipes, cleaning wipes, or any other wet nonwoven containing lotion having a pH of below 5 or 6.
