There is disclosed an nonwoven fabric suitable for use as, for example, an intake/distribution material for personal care products, made from nonwoven fabric where the fabric is made from directly formed, mixed size fibers. The fibers may be conjugate fibers. The fabric may have zones having larger fibers and zones having smaller fibers providing a means to vary the web properties, such as permeability, or the mixed size fibers may be uniformly distributed. The fibers may also be crimped. The process for making such a material is also disclosed. A zoned fiber fabric can provide rapid intake of an insult because of the placement of the high permeability zone in the insult target area and can also provide good distribution through the lower permeability but higher capillarity end zones.
A nonwoven fabric comprising direct formed fibers of mixed sizes larger than 7 microns and having a substantially uniform distribution of said mixed size fibers.
A nonwoven fabric comprising direct formed fibers of mixed sizes larger than 7 microns having a non-uniform distribution of said mixed size fibers such that said fabric has a high permeability zone and a low permeability zone in which the high permeability zone has a permeability of at least 1.5 times that of the low permeability zone.
