Abstract

The present disclosure relates to stranded elastomeric laminates (including bi-laminates and tri-laminates) comprising beamed elastics and may have inventive Dtex-to-Nonwoven-Basis-Weight-Ratios, Dtex-to-Spacing-Ratios, and/or Void-Area-to-Strand-Area-Ratios. The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.

Claims (24)

1. An elastomeric laminate, comprising:

a plurality of elastic strands between of first and second nonwovens;

wherein the plurality of elastic strands has an Average-Strand-Spacing from about 0.25 mm to about 4 mm;

wherein the plurality of elastic strands has an Average-Dtex from about 10 to about 400;

wherein the plurality of elastic strands has an Average-Pre-Strain from about 50% to about 300%; and

wherein a Dtex-to-Nonwoven-Basis-Weight-Ratio of a first elastic strand and of at least one of the first and second nonwovens is from about 1.5 to about 15.

2. The elastomeric laminate of claim 1 , wherein a first elastic strand of the first plurality of elastic strands comprises from about 2 to about 40 filaments, including first and second filaments, wherein the first and second filaments are disposed cross-sectionally side-by-side of each other, and wherein at least one discrete bond surrounds at least the first and second filaments.

3. The elastomeric laminate of claim 2 , wherein the at least one discrete bond overlaps at least 10 elastic strands of the first plurality of elastic strands.

4. The elastomeric laminate of claim 3 , wherein the at least one discrete bond surrounds at least 20 filaments of the at least 10 elastic strands.

5. The elastomeric laminate of claim 1 , wherein the plurality of elastic strands has an Average-Strand-Spacing from about 0.5 mm to about 2.5 mm.

6. The elastomeric laminate of claim 1 , wherein a Dtex-to-Spacing-Ratio of the plurality of elastic strands is from about 65:1 to about 150:1.

7. The elastomeric laminate of claim 1 , wherein the plurality of elastic strands comprises at least 100 elastic strands, and wherein each of the at least 100 elastic strands comprises at least 3 filaments.

8. The elastomeric laminate of claim 1 , further comprising at least one of:

a) a Percent-Contact-Area of at least one of: a) greater than about 10% at 100 um, b) greater than about 20% at 200 um, and c) greater than about 30% at 300 um;

b) a Force-Relaxation-Over-Time from about 5% to about 30%;

c) a Cantilever-Bending of less than about 40 mm;

d) a 2%-98%-Height-Value of <2.2 mm;

e) a Pressure-Under-Strand from about 0.1 to about 1 psi; and

f) a Section-Modulus of from about 2 gf/mm to about 15 gf/mm.

9. The elastomeric laminate of claim 1 , wherein the elastomeric laminate forms at least a portion of at least one of the group consisting of a belt, a chassis, a side panel, a topsheet, a backsheet, an ear panel, and combinations thereof, wherein the plurality of elastic strands comprises from about 40 to about 1000 elastic strands, wherein each of the elastic strands making up the about 40 to about 1000 elastic strands are overlapped by and partially surrounded by a plurality of discrete bonds.

10. The elastomeric laminate of claim 1 , wherein a third nonwoven is joined to the second nonwoven such that a tri-laminate is formed, and wherein an exterior surface of the third nonwoven and an exterior surface of the first nonwoven have different Percent-Contact-Areas.

11. The elastomeric laminate of claim 10 , wherein the third nonwoven is joined to the second nonwoven via adhesive.

12. The elastomeric laminate of claim 1 , wherein the first nonwoven layer has a basis weight from about 6 grams per square meter to about 35 grams per square meter, and wherein the second nonwoven layer has a basis weight from about 6 grams per square meter to about 35 grams per square meter.

13. The elastomeric laminate of claim 1 , wherein a Peel-Strength between the first and second nonwovens is from about 1 N/cm to about 15N/cm.
