Abstract

Claims (41)

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 the first and second nonwovens, wherein the laminate comprises a plurality of ultrasonic bonds;

wherein the laminate comprises a first inelastic region and an elastic region,

wherein the first inelastic region is void of elastomeric material, wherein the exterior surface of the laminate in the elastic region comprises an average TS7 value of about 12 db V 2 rms or less, and wherein the exterior surface of the laminate in the elastic region comprises an average TS750 value of about 115 db V 2 rms or less,

wherein at least one of the first nonwoven and the second nonwoven are hydroentangled.

2. The absorbent article of claim 1 , wherein the exterior surface of the laminate in the elastic region comprises an average TS7 value of at least 2 db V 2 rms.

3. The absorbent article of claim 1 , wherein the exterior surface of the laminate in the elastic region comprises an average TS750 value of at least 50 db V 2 rms.

9. The absorbent article of claim 1 , wherein the first nonwoven comprises an Average % Strain at Peak Force of from about 40% to about 60%.

10. The absorbent article of claim 1 , wherein the absorbent core comprises at least one channel.

11. The absorbent article of claim 1 , wherein the first nonwoven has an average bond area of about 8% to about 12%.

12. The absorbent article of claim 1 , wherein the first nonwoven comprises an average bond major dimension of about 1.25 mm to about 8 mm.

13. The absorbent article of claim 1 , wherein the first nonwoven comprises a bond site area of about 0.5 mm 2 to about 2.0 mm 2 .

14. 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 an elastomeric material, wherein the first nonwoven is hydroentangled,

wherein the laminate comprises a plurality of ultrasonic bonds, an inelastic region void of the elastomeric material and an elastic region,

wherein the first nonwoven has an Average Bond Area of about 14% or less and an Average Normalized Peak Force of at least 0.160 (N/cm)/(g/m 2 ), and

wherein the laminate comprises an exterior surface having an average TS750 value of about 115 db V2rms or less in the elastic region.
