WE CLAIM:

1. A retractive composite web comprising:
a) an extensible, fluid permeable substrate having at least one direction of extensibility in an XY plane;
b) a pattern of untensioned coalesced elastomeric stripes contained on an XY plane surface of the substrate in an add-on amount of between about 2.5 weight percent to about 100 weight percent of the composite web;
c) each longitudinal axis of the coalesced elastomeric stripes being oriented in the direction of substrate extensibility; and
d) the retractive composite being fluid permeable.

2. The retractive composite web according to claim 1 further comprising: the extensible, fluid permeable substrate having a basis weight of about 0.6 osy.

3. The retractive composite web according to any of the preceding claims 1-2 further comprising: the pattern being a regular pattern of 1 mm wide stripes spaced 1 cm apart.

4. The retractive composite web according to any of the preceding claims 1-2 further comprising: the pattern being a regular pattern of 4 mm wide stripes spaced 1 cm apart.

5. The retractive composite web according to any of the preceding claims 1-2 further comprising: the coverage area of stripes being between about 10.0 and about 40.0 percent of the surface area of the substrate.

6. The retractive composite web according to any of the preceding claims further comprising: the coalesced elastomer being provided in an add on amount of between about 2.5 weight percent to about 10.0 weight percent.

7. The retractive composite of Claim 6 having a modulus of elasticity of between about 31 psi and about 44 psi.

8. The retractive composite web according to any of the preceding claims 1-5 further comprising: the coalesced elastomer being provided in an add on amount of between about 35.0 weight percent to about 40.0 weight percent.

9. The retractive composite of Claim 8 having a modulus of elasticity of about 51 psi.

10. The retractive composite web according to any of the preceding claims 1-5 further comprising: the coalesced elastomer being provided in an add on amount of between about 60.0 weight percent to about 65.0 weight percent.

11. The retractive composite of Claim 10 having a modulus of elasticity of between about 64 psi and about 70 psi.

12. The retractive composite web according to any of the preceding claims 1-5 further comprising: the coalesced elastomer being provided in an add on amount of about 100.0 weight percent.

13. The retractive composite of Claim 12 having a modulus of elasticity of about 121 psi.

14. The retractive composite web according to any of the preceding claims 1-5 further comprising: the coalesced elastomer being provided in an add on amount of up to about 100.0 weight percent.

15. The retractive composite web according to any of the preceding claims further comprising: the coalesced elastomeric stripes being provided in an amount sufficient to provide less than about 81.8% first cycle hysteresis.

16. The retractive composite web according to any of the preceding claims further comprising: the coalesced elastomeric stripes being provided in an amount sufficient to provide less than about 61.2% second cycle hysteresis.

17. The retractive composite web according to any of the preceding claims further comprising: the coalesced elastomeric stripes being provided in an amount sufficient to provide less than about 35.0% first cycle immediate set.

18. The retractive composite web according to any of the preceding claims further comprising: the coalesced elastomeric stripes being provided in an amount sufficient to provide less than about 36.0% second cycle immediate set.

19. The retractive composite web according to any of the preceding claims 1-5, 6, 8, 10, 12, and 14-18 further comprising: the coalesced elastomeric stripes being provided in an amount sufficient to provide a modulus of elasticity greater than 21 psi.

20. The retractive composite web according to any of the preceding claims further comprising: the composite having a fluid intake time of between about 15 seconds to about 30 seconds for each cycle of a 3 cycle FIFE test.
