    • Disclosed is an absorbent structure having wet integrity greater than about 4.0 mN/gsm, softness greater than 8.0/J, pliability greater than about 70/N, and providing a substantially dry liquid-accepting surface after receiving a quantity of liquid. The structure includes an upper ply having an upper fluid receiving surface and a lower surface and including (i) a top stratum including synthetic matrix fibers bonded with a binder, the matrix fibers having length from about 2 to about 15 mm; (ii) a middle stratum in fluid communication with the top stratum, the middle stratum including natural fibers, superabsorbent particles and a binder; and (iii) a bottom stratum in fluid communication with the middle stratum, the bottom stratum including natural fibers and a binder. The structure also includes a lower ply in fluid communication with the upper ply, the lower ply having an upper surface and a lower surface and including at least one stratum including natural fibers, superabsorbent polymer particles, and a binder, wherein the lower surface of the upper ply has a surface area less than about 80% of the upper surface area of the lower ply.
    • 公开了一种具有大于约4.0mN / gsm,柔软度大于8.0 / J,柔软度大于约70 / N的湿度完整性的吸收结构,并且在接收一定量的液体之后提供基本干燥的受液表面。 该结构包括具有上流体接收表面和下表面的上层,并且包括(i)包含与粘合剂结合的合成基质纤维的顶层,所述基质纤维的长度为约2至约15mm; (ii)与顶层流体连通的中间层,中间层包括天然纤维,超吸收颗粒和粘合剂; 和(iii)与中间层流体连通的底层,底层包括天然纤维和粘合剂。 该结构还包括与上层流体连通的下层,下层具有上表面和下表面,并且包括至少一层包括天然纤维,超吸收性聚合物颗粒和粘合剂的层,其中, 上层具有小于下层的上表面积的约80%的表面积。
