摘要： This invention provides absorbent products, having a permeable cover made of a microperforated fibrillated thermoplastic film that has improved properties such as intimate, but nonoccluding contact with the body, yet providing comfort and resilience and immediate fluid acceptance and distribution. The cover is characterized by having non perforate regions and perforate regions, the perforate regions having a plurality of microholes defined by a network of fiberlike elements, the perforate regions being, at least in part, at elevations that are higher than the nonperforate regions. The perforate regions are caused to be at higher elevations by methods such as tensioning the cover or by partly adhering the cover to the absorbent body of the product or by combinations thereof. The microholes may be of different sizes and shapes. One embodiment provides an absorbent product having a cover with apertures larger than microholes, alone or in addition to microholes, and greater open area, so that viscous fluids such as menses can readily flow through, the cover having for example at least one group of large apertures or at least two different size groups of apertures, Additional improvement of fluid acceptance and distribution properties is obtained by corona discharge treatment of one side of the film before microperforating and by treating the microperforated film with surfactant.
