Transfer layer for absorbent article

摘要

A composite particularly suited for use as a transfer layer in an absorbent article has a first layer comprising a formed film having a plurality of capillary-sized apertured protuberances and a plurality of two-dimensional drains, and a second layer in intimate contact with an apertured end of said capillary-sized protuberances and spaced from the first layer in a z-direction, the second layer is either a three-dimensional apertured formed film or a nonwoven web. In embodiments where the second layer is a three-dimensional formed film, the film contains a plurality of capillary sized protuberances that are of smaller diameter compared to the protuberances in the first layer and optionally also contains a plurality of drains, which can be either two-dimensional or three-dimensional, or combinations thereof.

主权项

1. A formed film comprising:
a plurality of capillary-sized protuberances extending in a z-direction from a female side of the formed film toward a male side of the formed film, wherein the plurality of capillary-sized protuberances comprise a diameter of between 50 microns and 400 microns at the female side of the formed film; a plurality of two-dimensional drains formed between at least a portion of the plurality of capillary-sized protuberances at the female side of the formed film, wherein the plurality of two-dimensional drains lack a z-dimension beyond a nominal thickness of the formed film, and wherein the plurality of two-dimensional drains each comprise an average diameter greater than the diameter of the plurality of capillary-sized protuberances; and a plurality of apertures defined by ends of the plurality of protuberances at the male side of the formed film.
