Abstract:
1. A dryness indicator comprising: a wicking strip linearly continuous between a reservoir end and an opposed open end; a liquid-impermeable top layer disposed on one side of the wicking strip; a liquid-impermeable bottom layer disposed on the opposite side of the wicking strip, wherein the top layer is affixed to the bottom layer to only partially enclose the wicking strip such that the open end of the wicking strip extends beyond one of the top and bottom layers, and wherein the indicator is configured such that the open end of the wicking strip can be placed in liquid communication with an object or surface; and a reservoir including an oil-based colorant with the potential to be in liquid communication with the reservoir end of the wicking strip, wherein the reservoir is sealed against exposure to water-based fluid and wherein the wicking strip is configured such that colorant wicking from the reservoir end and an unreacted water-based fluid wicking from the open end meet to define a timing line.
