HIGH-PERFORMANCE ABSORBENT STRUCTURE

摘要

Disclosed is an absorbent structure having wet in-tegrity higher than about 4.0 kN/gsm, softness higher than 8.0/J, pliability higher than about 70/N, and providing a sub-stantially dry liquid-accepting surface after receiving a quan-tity of liquid. The structure includes an upper ply (82) having an upper fluid receiving surface and a lower surface and in-cluding (i) a top stratum (6) including synthetic matrix fibers bonded with a binder, the matrix fibers having a length from about 2 to about 15 mm; (ii) a middle stratum (8) in fluid communication with the top stratum (6), the middle stratum (8) including natural fibers, superabsorbent particles and a binder; and (iii) a bottom stratum (10) in fluid communi-cation with the middle stratum (8), the bottom stratum (10) including natural fibers and a binder. The structure also in-cludes a lower ply (4) in fluid communication with the upper ply (2), the lower ply (4) having an upper surface and a lower surface and including at least one stratum (13) including nat-ural fibers, superabsorbent polymer particles, and a binder, wherein the lower surface of the upper ply (2) has a surface area less than about 80 % of the upper surface area of the lower ply (4).
