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 nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.
Claims20
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 V2rms or less, and wherein the exterior surface of the laminate in the elastic region comprises an average TS750 value of about 115 db V2rms or less,
- wherein at least one of the first nonwoven and the second nonwoven are hydroentangled.
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/m2), and
- wherein the laminate comprises an exterior surface having an average TS750 value of about 115 db V2rms or less in the elastic region.
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 first spunbond nonwoven is hydroentangled,
- wherein the laminate comprises a plurality of ultrasonic bonds, an elastic region, and an inelastic region void of the elastomeric material,
- wherein the first spunbond nonwoven has an Average Bond Area of about 12% or less and an average bond major dimension of about 1.25 mm or greater, and
- wherein an exterior surface of the lamiante in the elastic region comprises an average TS750 value in the range of about 50 db V2rms to about 115 db V2rms.
