摘要:
A two-layer bonded highloft nonwoven particle entrapment pad, for entrapping soils tracked by pets, comprises an open, porous, bonded highloft nonwoven top layer and an otherwise solid, impenetrable bottom layer or structure secured to its underside. The highloft top layer is manufactured from a synthetic material consisting of numerous matrices or cross-over connections which create open porous sieve-like varieties, wherein a web structure of the highloft layer comprises a distinct top, middle, and bottom that is capable of allowing the particles and the litter to enter and be entrapped therein via gravity when stepped upon. A sticky, tackified adhesive maintained on a complex of bonded fibers of the highloft, said adhesive increases its holding capacity as does mechanical abrasion to the top surface of the highloft nonwoven. The present bonded, highloft pad can be manufactured from a variety of densities, deniers and depths from an airlaid, a drylaid, or a wetlaid process.
