Abstract
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 m2/g to about 4 m2/g.
Claims16
A nonwoven substrate for an absorbent article comprising a layer of fibers, wherein the nonwoven substrate has a specific surface area in the range of about 0.62/g to about 3.5 m2/g, wherein a plurality of the fibers each comprise fibrils extending outwardly from a surface of the fibers, wherein the fibrils comprise glycerol tristearate, wherein the plurality of fibers are free of droplets of the glycerol tristearate, wherein the plurality of the fibers are formed from a composition comprising a polyolefin and about 11% to about 35% of the glycerol tristearate by weight of the composition, and wherein the nonwoven substrate has a low surface tension fluid strikethrough time to basis weight ratio in the range of about 0.35s/gsm to about 5.0s/gsm.
A nonwoven substrate for an absorbent article comprising a layer of fibers, wherein the nonwoven substrate has a low surface tension fluid strikethrough time to basis weight ratio in the range of about 0.37s/gsm to about 5s/gsm, wherein a plurality of the fibers each comprise fibrils extending outwardly from a surface of the fibers, and wherein the plurality of the fibers are directly made from a composition comprising a polyolefin and about 11% to about 35% of glycerol tristearate by weight of the composition, and wherein the nonwoven substrate has a specific surface area in the range of about 1 m2/g to about 4 m2/g.
