Prestrained stretched laminates
Stretched laminates with prestrained elastics.
1. A process for making a prestrained stretched laminate, comprising:
prestraining at least one elongate elastic element at least 10% in a primary direction to form a prestrained elongate elastic element;
attaching the prestrained elongate elastic element, while the elongate elastic element is prestrained, to an inelastic layer to form a precursor laminate; and
extending the precursor laminate at least 35% in the primary direction to form the prestrained stretched laminate, wherein the inelastic layer of the precursor laminate is extended inelastically.
2. The process of claim 1 , wherein the prestraining includes prestraining the at least one elongate elastic element at least 50% in the primary direction to form the prestrained elongate elastic element.
3. The process of claim 1 , wherein the prestraining includes prestraining the at least one elongate elastic element at least 100% in the primary direction to form the prestrained elongate elastic element.
4. The process of claim 1 , wherein the prestrained elongate elastic element is one of a plurality of elongate elastic element and the prestraining includes prestraining the plurality of elongate elastic element.
5. The process of claim 1 , wherein the extending includes extending the precursor laminate at least 33% in the primary direction to form the prestrained stretched laminate.
6. The process of claim 1 , wherein the extending includes extending the precursor laminate at least 50% in the primary direction to form the prestrained stretched laminate.
7. The process of claim 1 , wherein the extending includes extending the precursor laminate at least 100% in the primary direction to form the prestrained stretched laminate.
8. The process of claim 1 , wherein the extending includes extending the precursor laminate at least 200% in the primary direction to form the prestrained stretched laminate.
9. The process of claim 1 , wherein the inelastic layer is a first inelastic layer and the attaching includes attaching the prestrained elongate elastic element, while the elongate elastic element is prestrained, to a second inelastic layer to form the precursor laminate.
10. The process of claim 1 , wherein the prestrained stretch laminate is configured to be at least one of a leg band and a waist band.
11. The process of claim 1 , wherein the prestrained stretch laminate comprises an overall relaxed thickness from greater than about 1 mm.
12. The process of claim 1 , wherein the prestrained stretch laminate comprises shirrs.
13. The process of claim 1 , further comprising the step of attaching the prestrained stretch laminate to a chassis of an absorbent article.
14. The process of claim 1 , wherein the inelastic layer is a nonwoven.
15. The process of claim 1 , wherein the inelastic layer is a film.
16. A process for making a prestrained stretched laminate, comprising:
prestraining at least one elongate elastic element at least 10% in a primary direction to form a prestrained elongate elastic element;
attaching the prestrained elongate elastic element, while the elongate elastic element is prestrained, to a first inelastic layer and a second inelastic layer to form a precursor laminate; and
extending the precursor laminate at least 35% in the primary direction to form the prestrained stretched laminate, wherein the first inelastic layer and the second inelastic layer of the precursor laminate are extended inelastically.
17. The process of claim 16 , wherein the first inelastic layer is at least one of a nonwoven and a film.
18. The process of claim 17 , wherein the second inelastic layer is at least one of a nonwoven and a film.
