Abstract
A carded staple fiber nonwoven comprising three or more stratums. The carded staple fiber nonwoven has a basis weight of up to about 175 gsm and includes a blend of absorbing fibers, stiffening fibers and filler fibers. The carded staple fiber nonwoven is heat stiffened and the three or more stratums are integrated without adhesives.
Claims15
A sanitary napkin comprising a topsheet, a backsheet, and an absorbent core, the absorbent core comprising a fluid acquisition/distribution layer and a fluid storage layer comprising particles of absorbent gelling material, wherein the fluid acquisition/distribution layer is a single integrated layer formed of a staple fiber nonwoven comprising a plurality of strata including a wearer-facing stratum and a garment facing stratum, the staple fiber nonwoven comprising a combination of staple fibers including bicomponent fibers and cellulosic fibers, wherein the cellulosic fibers are present in greater weight percentage in the garment-facing stratum and lesser weight percentage in the wearer-facing stratum;
- wherein the bicomponent fibers have a PE/PET sheath-core configuration;
- wherein the staple fiber nonwoven is heat stiffened, wherein at least a portion of individual ones of the bicomponent fibers are bonded together via bonds between sheaths thereof;
- wherein the cellulosic fibers and the bicomponent fibers are integrated within the single integrated layer, wherein the wearer facing stratum comprises from about 10% to about 50% by weight of cellulosic fibers and from about 10% to about 50% by weight of bicomponent fibers, wherein the garment facing stratum comprises greater than 60% of cellulosic fibers, and wherein the fluid acquisition/distribution layer has a caliper of between about 2 millimeters and about 4 millimeters and a basis weight of 100 gsm to 175 gsm.
A sanitary napkin comprising a backsheet, a fluid acquisition/distribution layer having a body facing surface and a garment facing surface and a fluid storage layer comprising particles of absorbent gelling material, wherein the fluid acquisition/distribution layer is a single integrated layer formed of a staple fiber nonwoven comprising a plurality of strata including a wearer-facing stratum and a garment facing stratum, the staple fiber nonwoven comprising a combination of staple fibers including bicomponent fibers and cellulosic fibers, wherein the cellulosic fibers are present in greater weight percentage in the garment-facing stratum and lesser weight percentage in the wearer-facing stratum;
- wherein the staple fiber nonwoven is heat stiffened such that at least a portion of individual ones of the bicomponent fibers are bonded together via bonds between sheaths thereof;
- wherein the cellulosic fibers and the bicomponent fibers are integrated within the single integrated layer;
- wherein the fluid acquisition/distribution layer has a caliper of between about 2 millimeters and about 4 millimeters and a basis weight of 100 gsm to 175 gsm, wherein the cellulosic fibers have a linear density of between about 1 dtex and about 6 dtex, wherein the bicomponent fibers have a linear density of between about 5 dtex to about 15 dtex, wherein the wearer facing stratum comprises from about 10% to about 50% by weight of cellulosic fibers and from about 10% to about 50% by weight of bicomponent fibers, and wherein the garment facing stratum comprises greater than 60% of cellulosic fibers.
