Abstract: There is provided a new nonwoven material for personal care products made of fibers, binder in an amount between 1 and 6 weight percent and superabsorbent in an amount between 1 and 80 weight percent, where the superabsorbent is contained in micro-pockets in the nonwoven.

These materials exhibit good permeability to liquid in the pre- and post-wetted conditions, thus avoiding gel blocking and other negative effects of superabsorbent swelling within a fabric. Such a fibrous material is useful in personal care products, like diapers, training pants, incontinence garments and feminine hygiene products.
