Abstract
A method of manufacturing and compositions required to produce a pH indicating absorbent pad. The method includes preparing a pH indicating dye composition, preparing a binder composition containing an emulsion polymer and surfactant and a pH indicating dye composition, then at least partially immersing or otherwise saturating nonwoven fibers, including at least some cellulose or cellulose-derived fibers, into the pH indicating binder composition, producing a pH indicating nonwoven material. The method further includes bonding the pH indicating nonwoven material to an absorbent core to produce the pH indicating absorbent pad.
