Abstract

Disclosed herein is a composite comprising at least one heat shrinkable adhesive layer stitch-bonded with yarns, which shrink less than the adhesive layer or do not shrink, when the adhesive layer is exposed to heat. The stitch-bonded yarns form loops upstanding from the shrunk adhesive layer and the loops create a textured surface on the composite, and the composite is substantially inelastic after the adhesive layer is shrunk. The composite may further comprise at least one fibrous layer stitch-bonded to the shrinkable adhesive layer, and the fibrous layer is less shrinkable than the adhesive layer or is substantially non-shrinkable.

Claims (22)

1. A method of making a composite comprising:

providing a heat shrinkable layer;

stitch-bonding the heat shrinkable layer with stitching yarns that are less shrinkable than the heat shrinkable layer;

exposing the stitch-bonded heat shrinkable layer to heat to shrink said layer; and said shrinkage causing loops emanating from the shrunk layer to form from the stitching yarns.

2. The method of claim 1 , wherein the step of providing the heat shrinkable layer comprises the step of selecting said layer to be shrinkable by about 10% to about 50% in at least one direction.

3. The method of claim 2 , wherein the heat shrinkable layer is shrinkable in two directions.

4. The method of claim 1 , wherein the step of providing the heat shrinkable layer comprises the step of selecting said layer to be shrinkable by at least about 20% in at least one direction.

5. The method of claim 4 , wherein the heat shrinkable layer is shrinkable in two directions.

6. The method of claim 1 , wherein the step of stitch-bonding the heat shrinkable layer comprises stitching in two or more distinct stitching patterns.

7. The method of claim 1 , wherein the composite is laminated to a backing layer.

8. The method of claim 1 , wherein the composite is embossed to a backing layer.

9. The method of claim 1 , further comprising the steps of selecting a fibrous layer and stitch-bonding the fibrous layer with the heat shrinkable layer.

10. The method of claim 9 , wherein the fibrous layer comprises a spunlaced nonwoven.

11. The method of claim 9 , wherein the step of selecting the fibrous layer includes selecting a fibrous layer that is substantially non-shrinkable.

12. The method of claim 9 , wherein the step of selecting the fibrous layer includes selecting a fibrous layer that is less shrinkable than the heat shrinkable layer.

13. The method of claim 9 , further comprising the step of forming second loops created from the fibrous layer.

14. The method of claim 1 , wherein the heat shrinkable layer is an adhesive layer.

15. The method of claim 1 further comprising the steps of providing an adhesive layer and bonding the adhesive layer to the heat shrinkable layer.

16. The method of claim 15 , wherein the adhesive layer is shrinkable.

17. The method of claim 15 , wherein the adhesive layer is substantially non-shrinkable.

18. The method of claim 14 , wherein the step of exposing the stitch-bonded adhesive layer includes the step of bonding the stitching yarns to the adhesive layer.

19. The method of claim 15 , wherein the step of exposing the stitch-bonded adhesive layer includes the step of bonding the stitching yarns to the adhesive layer.
