摘要： An absorbent article having improved handling of body exudates. The absorbent article can minimize the amount of body exudates in contact with a wearer's skin and can minimize the incidence of leakage of body exudates from the absorbent article. The benefits of the absorbent article are achieved, in part, by a body facing material having features that help minimize contact of body exudates with the wearer's skin while also being constructed so that the body facing material does not stick to the wearer's skin in use. The body facing material includes a plurality of hollow projections, a plurality of apertures and bonded areas. The bonded areas may be formed with adhesive or by mechanical bonds.

摘要： The present invention is directed to a process and apparatus for formation of a fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. The laminate web also includes a plurality of apertures interspersed with the projections. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in a forming surface thereby forming the hollow projections. The force of the entangling fluid also causes the fibers of the two layers to be moved around protrusions present in the forming surface thereby forming the apertures.
