| titleOfInvention |
Apertured films having durable wettability and processes for making them |
| abstract |
This invention relates to a process for forming a single-layer, durably wettable polymeric web having a plurality of apertures. This process comprises melting a mixture of at least one thermoplastic polymer and at least one migratable surfactant and extruding the mixture to form a single-layer, substantially continuous polymeric film. The film is then apertured using high pressure fluid flows. Aperture formation is conducted when the single-layer polymeric film has a contact angle of at least about 30~, to minimize wash-off of the surfactant impregnated in the polymer web. The invention also relates to durably-wettable apertured webs. |
