Abstract

A nursing pad of multi-ply construction that is conformable and comfortable with a high resistance to strike-through and low sticking properties. The pad includes a lightweight layer of thermoplastic polymeric microfibers on one side of an absorbent middle layer containing thermoplastic polymeric fibers and, on the opposite side of the middle layer, a lightweight spun-bonded continuous filament thermoplastic polymer layer. The microfiber layer provides resistance to strike-through and will tend to cling to many fabrics preventing displacement of the pad during normal use. The continuous filament layer provides comfort and strength with a reduced tendency to stick. The combination is bonded by embossing wherein the embossing pattern on the microfiber side occupies a lower percentage of the surface area than the bonding pattern on the continuous filament side.

Dependent claims

A flexible, breathable nursing pad having low stick properties, consisting essentially of, a layer having a basis weight of from about 0.2 oz/yd.sup.2 to 1.5 oz/yd.sup.2 of synthetic polymeric microfibers having an average fiber diameter of up to 10 microns and a tendency to cling to garments containing natural fibers and a resistance to the passage of aqueous liquids of at least 60 min. according to the Mason jar test, an absorbent middle layer comprising 30 to 50% polymeric fibers by weight and having a basis weight from about 150 g/yd.sup.2 to about 250 g/yd.sup.2, and

a spunbonded continuous synthetic polymeric filament layer having a basis weight of from about 0.25 oz/yd.sup.2 to 1.5 oz/yd.sup.2 on the other side of said absorbent layer opposite from said microfiber layer,
said combination being bonded by means of embossments wherein the embossing pattern on the microfiber side occupies from about 1% to 5% of the surface area and the embossing pattern on the continuous filament side occupies from about 10% to 20% of the surface area.
