Abstract

An absorbent pad is provided which includes an absorbent layer which serves as a reservoir for liquid and has a liquid impervious barrier over one surface thereof. The liquid is applied to the opposite surface of the barrier and is conducted by means of wicking material to the sides of the barrier and into the absorbent layer. This arrangement enhances drying of the upper surface of the barrier and wicking material shortly after application of the liquid. A hydrophobic porus of open weave material can be provided over the wicking material to protect it and to provide a surface through which the liquid can reach the wicking material and the barrier sheet. The barrier sheet can have multiple channels formed in the liquid receiving surface thereof to disperse the liquid toward the edges thereof.
