Abstract
The present disclosure relates to an absorbent garment comprising an absorbent core having a nonwoven core cover that offers improved performance on holding back fine particulate material after having been exposed to external strain.
Claims20
An absorbent garment comprising:
- an absorbent core, including a superabsorbent polymer material, a hot melt adhesive, and a core cover;
- wherein the core cover surrounds at least a part of the absorbent core and includes a nonwoven web;
- wherein the nonwoven web has:
- a layer of meltblown fibers sandwiched between two nonwoven layers of spunbonded fibers, and a weight of the spunbond fibers ranges from 80% to 95% of a basis weight of the nonwoven web;
- the basis weight ranging from 8 to 20 g/m2 before being subjected to a first prescribed strain;
- an initial air permeability of less than 60 m3/(m2·min) before being subjected to a first prescribed strain;
- and
- a subsequent air permeability that is less than 18% greater than the initial air permeability after the nonwoven web is subjected to the first prescribed strain;
- and
- wherein the first prescribed strain is at least 10%.

An absorbent garment comprising:
- an absorbent core comprising a superabsorbent polymer material, a hot melt adhesive, and a core cover, wherein the superabsorbent polymer material is more than 80% by weight of the absorbent core, wherein the core cover surrounds at least a portion of the absorbent core and includes a nonwoven web, and wherein the nonwoven web has:
- a layer of meltblown fibers sandwiched between two nonwoven layers of spunbonded fibers, and a weight of the spunbond fibers ranges from 80% to 95% of a basis weight of the nonwoven web;
- the basis weight ranging from 8 to 20 g/m2 before being subjected to a prescribed strain;
- an initial air permeability of less than 60 m3/(m2·min) before being subjected to a prescribed strain;
- and
- a subsequent air permeability that is less than 18% greater than the initial air permeability after the nonwoven web is subjected to the prescribed strain;
- wherein the prescribed strain is at least 10%.
4 more elements
An absorbent garment comprising:
- an absorbent core comprising a superabsorbent polymer material, a hot melt adhesive, and a core cover, wherein the superabsorbent polymer material is more than 80% by weight of the absorbent core, wherein the absorbent core has less than 5% by weight of airfelt material, wherein the core cover surrounds at least a portion of the absorbent core and includes a nonwoven web, and wherein the nonwoven web has:
- a layer of meltblown fibers sandwiched between two nonwoven layers of spunbonded fibers, and a weight of the spunbond fibers ranges from 80% to 95% of a basis weight of the nonwoven web;
- and
- an air permeability that is less than 70.8 m3/(m2·min) after the nonwoven web is subjected to a prescribed strain of at least 10%.
