Abstract

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article also includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a laminate formed from a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds; and the first nonwoven includes an exterior surface having an average TS750 value of 5 db V2rms or less.

Claims (35)

1. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and

an ear joined to the chassis and comprising:

a laminate comprising a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens, wherein the laminate further comprises a plurality of ultrasonic bonds;

wherein the first nonwoven comprises an exterior surface having an average TS750 value of 5 db V 2 rms or less; and

wherein the laminate comprises a first inelastic region and an elastic region, wherein the first inelastic region is void of elastomeric material and wherein the exterior surface of the first nonwoven in the elastic region comprises an average TS7 value of 12 db V 2 rms or less.

2. The absorbent article of claim 1 wherein the exterior surface of the first nonwoven in the elastic region comprises an average TS750 value of 100 db V 2 rms or less.

3. The absorbent article of claim 1 wherein the exterior surface of the first nonwoven in the first inelastic region comprises an average TS750 value of 10 db V 2 rms or less.

4. The absorbent article of claim 1 wherein the laminate comprises an Average Load at Break of 25N or greater.

5. The absorbent article of claim 1 wherein the first nonwoven comprises a spunbond noncrimped fiber nonwoven.

6. The absorbent article of claim 5 wherein the first nonwoven comprises an Average Normalized Peak Force of at least 0.160 (N/cm)/(g/m 2 ).

7. The absorbent article of claim 5 wherein the first nonwoven comprises an Average % Strain at Peak Force of 60% or less.

8. The absorbent article of claim 7 wherein the Average % Strain at Peak Force of 40% or more.

9. The absorbent article of claim 1 wherein the first nonwoven has an average bond area of about 12% or less.

10. The absorbent article of claim 1 wherein the first nonwoven comprises an average bond major dimension of at least 1.25 mm.

11. The absorbent article of claim 10 wherein the first nonwoven comprises a bond site area of 0.5 mm 2 or greater.

12. The absorbent article of claim 1 wherein the second nonwoven comprises a second exterior surface having an average TS750 value of 5 db V 2 rms or less.

13. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and

an ear joined to the chassis and comprising:

a laminate comprising a first spunbond nonwoven and an elastomeric material, wherein the laminate further comprises a plurality of ultrasonic bonds, an inelastic region void of the elastomeric material and an elastic region;

the first spunbond nonwoven has an Average Bond Area of 12% or less and an Average Normalized Peak Force of at least 0.160 (N/cm)/(g/m 2 ); and wherein the first spunbond nonwoven comprises an exterior surface having an average TS750 value of 10 db V2rms or less in the inelastic region.

14. The absorbent article of claim 13 wherein the first spunbond nonwoven is void of crimped fibers.

15. The absorbent article of claim 13 wherein the first spunbond nonwoven comprises an average bond width of 1.25 mm or greater.

16. The absorbent article of claim 15 wherein the first spunbond nonwoven comprises an average bond height of 1.25 mm or greater.

17. The absorbent article of claim 13 wherein the first spunbond nonwoven comprises an average TS750 value of 5 db V 2 rms or less.

18. An absorbent article comprising:

a first waist region, a second waist region, a crotch region disposed between the first and second waist regions;

a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and

an ear joined to the chassis and comprising:

a laminate comprising a first spunbond nonwoven and an elastomeric material, wherein the laminate further comprises a plurality of ultrasonic bonds, an elastic region, and an inelastic region void of the elastomeric material; and

the first spunbond nonwoven has an Average Bond Area of 12% or less and an average bond major dimension of 1.25 mm or greater; and

wherein an exterior surface of the first spunbond nonwoven in the elastic region comprises an average TS750 value of 100 db V 2 rms or less.
