US 8,133,825 B2 · Dispersible wet wipes

Abstract

A wet wipe comprises a nonwoven material. The nonwoven material comprises a fibrous material and a binder composition. The binder composition includes a cationic ion-sensitive emulsion polymer, which can comprise the emulsion polymerization product of at least one hydrophobic monomer which has been stabilized by a solution-polymerization-derived cationic ion-sensitive polymer stabilizer. In some aspects, a solution-polymerization-derived cationic ion-sensitive polymer binder can be solution blended with the already-formed cationic ion-sensitive emulsion polymer to provide additional benefits. In other aspects, the solution-polymerization-derived cationic ion-sensitive polymer binder is the same as the s-solution-polymerization-derived cationic ion-sensitive polymer stabilizer.
