Elastic diaper component

1. A method of making an elastic diaper component, comprising the steps of:

providing an elastic laminate including an elastic layer and a first fabric layer, wherein the elastic laminate has a recoverable extension of at least 20% when an extension force E1 is applied; and

integratively pre-stretching in an amalgamated manner across a width of the elastic laminate so that the elastic laminate will stretch to the same recoverable extension when a reduced extension force E2 is applied; manner wherein the integratively pre-stretching step comprises urging the elastic laminate laterally outward to temporarily widen its span, causing the elastic laminate to travel through a curved route to temporarily widen its span, and/or conveying a portion of the elastic laminate through an offset path to temporarily widen its span;

whereby, when the elastic laminate is used in the elastic diaper component, a lesser fitting force F fit is required to extend the elastic component to a desired length during an initial fitting of a diaper on a wearer, compared to the fitting force required to extend an elastic diaper component comprising a laminate that has not been prestretched.

2. A method as set forth in claim 1 , wherein the integrative pre-stretching step comprises an at least 100% extension of the elastic laminate.

3. A method as set forth in claim 2 , wherein the first fabric layer is an inelastic nonwoven layer.

4. A method as set forth in claim 3 , wherein the elastic laminate comprises a second fabric layer and wherein the elastic layer is positioned between the two fabric layers.

5. A method as set forth in claim 4 , wherein the second fabric layer is an inelastic nonwoven layer.

6. A method as set forth in claim 4 , wherein the first fabric layer and/or the second fabric layer is mechanically manipulated prior to said integrative pre-stretching step to allow it to extend/retract with the elastic layer.

7. A method as set forth in claim 4 , wherein the first fabric layer and/or the second fabric layer have interruptions formed therein prior to said integrative pre-stretching step; wherein:

the interruptions extend partially through the layer thickness of the fabric layer and tendons extend through the rest of the layer thickness;

the interruptions extend 50% to 99% through the thickness of the fabric layer;

the interruptions comprise die-cuts, kiss-cuts, slits, scores, laser-cuts, and/or ultrasound-cuts;

the interruptions are distal interruptions and the tendons are proximal interruptions;

and wherein said integrative pre-stretching step comprises rupturing at least some of said tendons.

8. A method as set forth in claim 7 , wherein said rupturing step results in the fabric layer being divided into separable fabric segments which diverge upon elongation and converge upon recovery.

9. A method as set forth in claim 1 , wherein said integratively stretching step comprises stretching the elastic laminate in an amalgamated manner across portions of its width.

10. A method as set forth in claim 1 , further comprising the step of separating the elastic laminate into side panel shapes, fastener tape shapes, or belt shapes.

11. A method as set forth in claim 10 , wherein said separating step is performed after said integrative stretching step.

12. A method comprising incorporating a pre-stretched component made by the method set forth in claim 11 into a diaper, wherein said integrative pre-stretching step is performed prior to said incorporation.

13. A method comprising the steps of providing an elastic laminate and integratively pre-stretching in an amalgamated manner across a width of the elastic laminate; wherein the integratively pre-stretching step comprises urging the elastic laminate laterally outward to temporarily widen its span, causing the elastic laminate to travel through a curved route to temporarily widen its span, and/or conveying a portion of the elastic laminate through an offset path to temporarily widen its span;

wherein the laminate comprises an elastic layer and at least one fabric layer laminated thereto;

wherein the fabric layer has interruptions formed therein prior to said integrative prestretching step;

wherein the interruptions extend partially through the layer thickness of the fabric layer and tendons extend the rest of the way through the fabric thickness; and

wherein said integrative pre-stretching step comprises rupturing at least some of said tendons and dividing the fabric layer into separable fabric segments which diverge upon elongation and converge upon recovery.

14. A method as set forth in claim 13 , wherein the interruptions extend 50% to 99% through the thickness of the fabric layer; wherein the interruptions comprise die-cuts, kiss-cuts, slits, scores, laser-cuts, and/or ultrasound-cuts; and wherein the interruptions are distal interruptions and the tendons are proximal interruptions.
