With the use of surfactants the properties of hydrophobic polypropylene (PP) nonwovens have been altered such that they are more conducive to carrying the liquid away from the skin for use in personal care products. The nonwovens were topically treated with various surfactants and the breakthrough pressures, wettability and vapor sorption properties were determined. The wettability testing did not show a significant decrease in the hydrophobic tendencies of the nonwovens. The breakthrough pressure study showed that the surfactants displayed promising improvements in not only allowing water to spread over the surface so that it could reach the absorbent layers underneath the PP more readily, but also in continuing to show these effects after several rewettings.
