A nonwoven substrate for an absorbent article including a layer of fibers is provided. The nonwoven substrate has a low surface tension fluid strikethrough time to basis weight ratio in the range of about 0.37 s/gsm to about 5 s/gsm. A plurality of the fibers each include fibrils extending outwardly from a surface of the fibers. The plurality of the fibers are made from a composition including a polyolefin and about 11% to about 35% of glycerol tristearate by weight of the composition. The nonwoven substrate has a specific surface area in the range of about 1 m/g to about 4 m/g.

Absorbent articles with nonwoven substrates having fibrils

An absorbent article to be worn the lower torso is provided. The absorbent article comprises a chassis comprising a topsheet, a backsheet, an absorbent core, and a pair of longitudinal barrier cuffs attached to the chassis. Each of the longitudinal barrier cuffs comprises a web of material. The web of material comprises a first nonwoven component layer, and a second nonwoven component layer. Each of the longitudinal barrier cuffs comprises a longitudinal zone of attachment where each of the longitudinal barrier cuff attaches to the chassis, a longitudinal free edge, and a plurality of mechanical bonds disposed between the longitudinal zone of attachment and the free edge. The plurality of mechanical bonds attach one of a first portion of the web of material to a second portion of the web of material, and the web of material to a portion of the absorbent article.

Absorbent article with bonded web material

A wipe comprises a nonwoven substrate comprising a layer of fibers. A plurality of the fibers comprise fibrils extending outwardly therefrom only after a time period. The time period is greater than about 24 hours post-nonwoven substrate formation under ambient conditions.

The present disclosure is directed, in part, to an absorbent article comprising a liquid pervious material, a liquid impervious material, and an absorbent core disposed at least partially intermediate the liquid pervious material and the liquid impervious material. The absorbent article comprises one or more nonwoven substrates each comprising one or more layers of fibers. A plurality of the fibers each comprise a plurality of fibrils extending outwardly from a surface of the fibers. The plurality of fibrils comprise a lipid ester.

An absorbent article to be worn about the lower torso, the absorbent article comprising a chassis comprising a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinal barrier cuffs attached to the chassis. Each longitudinal cuff is formed of a web of material, the web of material having first and second opposing surfaces. The web of material comprises a nonwoven component layer comprising fibers having a number-average diameter of less than about 1 micron, a mass-average diameter of less than about 1.5 microns, and a ratio of the mass-average diameter to the number-average diameter less than about 2. The absorbent article further comprises a hydrophobic coating disposed on at least one surface of the web of material such that a coated web of material is formed, the hydrophobic surface coating comprising a solventless, multicomponent silicone composition including at least two silicone polymers and being substantially free of aminosilicones.

Absorbent article with containment barrier

The present disclosure is directed, in part, to a method of forming an absorbent article. The method comprises providing a nonwoven substrate comprising a plurality of fibers. At least some of the plurality of fibers comprise a plurality of fibrils extending outwardly from a surface of the fibers. The fibrils comprise a lipid ester having a melting point greater than 35&#xb0; C. The method comprises incorporating the nonwoven substrate into the absorbent article.

Methods for forming absorbent articles with nonwoven substrates

An absorbent article comprising a chassis comprising a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinal barrier cuffs attached to the chassis. Each longitudinal cuff is formed of a web of material having first and second opposing surfaces and comprising a nonwoven component layer comprising fibers having a number-average diameter of less than about 1 micron, a mass-average diameter of less than about 1.5 microns, and a ratio of the mass-average diameter to the number-average diameter less than about 2. The absorbent article further comprises a hydrophobic coating disposed on at least one surface of the web of material.
