Abstract:
A layered pad comprising a bottom impervious layer, a top layer of a fibrous high loft non woven capable of entrapping small or large particles and preventing their scatter, optionally combined with a middle layer of fibers and super absorbent agent, wherein liquids pass through the top layer, become absorbed by the middle layer, and evaporate; and a method for manufacturing a non-woven pad layer having an at least partially open-ended configuration. The method of manufacturing the open-ended non-woven layer includes cutting at least one surface of the non-woven layer and then abrading the cut surface with an abrading tool.
