Claims18
A multi-ply fibrous structure comprising a first fibrous structure ply and a second fibrous structure ply bonded together at one or more thermal bond points, wherein each of the first and second fibrous structure plies comprises two or more regions not present within the one or more thermal bond points, wherein the two or more regions exhibit different density values relative to one another, wherein the first and second fibrous structure plies comprise a plurality of filaments comprising a thermoplastic polymer selected from the group consisting of:
- polypropylene, polyethylene, polyester, polylactic acid, polyhydroxyalkanoate, polycaprolactone, styrene-butadiene-styrene block copolymer, styrene-isoprene-styrene block copolymer, poly-urethane, and mixtures thereof and a plurality of solid additives, wherein the multi-ply fibrous structure comprises one or more z-direction void volumes of at least 20 μm between the first and second fibrous structure plies.
