1-119. (canceled)
A multilayer absorbent composite comprising a first cohesive layer selected from the group consisting of a nonwoven fabric and a film, and an absorbent layer overlying the first cohesive layer, the absorbent layer comprising a blend of meltblown fibers and a solid additive, wherein the multilayer absorbent composite exhibits a wet Mullen Burst Strength from about 10 psi or greater.
A product assembly adapted to absorb liquids exuded from a product, comprising:
- a substantially rigid support member having an upper surface upon which a product may be placed, and an opposing lower surface;
- and
- an multilayer absorbent composite positioned overlying said support member, the multilayer absorbent composite comprising a first cohesive layer selected from the group consisting of a nonwoven fabric and a film, and an absorbent layer overlying the first cohesive layer, the absorbent layer comprising a blend of meltblown fibers and a solid additive, wherein the multilayer absorbent composite exhibits a wet Mullen Burst Strength from about 10 psi or greater.
A method of preparing a multilayer absorbent composite comprising the steps of:
- providing a cohesive layer selected from the group consisting of a nonwoven fabric and a film;
- depositing an absorbent layer comprising a blend of meltblown fibers and a solid additive overlying the cohesive layer, wherein the multilayer absorbent composite exhibits a dry/wet Mullen Burst Strength greater than 10 psi.
