The present invention is directed to an air-laid composition comprising absorbent, binder, and synthetic fibers, wherein the synthetic fibers have a modulus greater than about 2 grams per denier, and a percent crimp of less than about 30%. The absorbent comprises about 40 to 80% of the weight of the composition. The binder comprises about 3-15% of the weight of the composition. The synthetic fibers comprise about 10-50% of the weight of the composition. The binder is selected from the class comprising conventional latex systems, hot melt adhesive, or binder fibers, or a mixture of these. The absorbent comprises natural absorbents or super absorbent polymer, or a combination of these. The natural absorbent materials are selected from the class consisting of wood pulp fluff, cotton, cotton linters, and regenerated cellulose fibers. The super absorbent polymer is selected from the class of agar, pectin, guar gum and synthetic hydrogel polymers. The synthetic fibers are selected from the class of polyolefins, such polyethylene, polypropylene and the like; polyesters such as polyethylene terephthalate and the like; polyamides such as nylon 6, nylon 6,6, and the like; acrylics; as well as mixtures and copolymers thereof. The synthetic fibers have an average length of from about 3-18 mm.
