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.
Claims19
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.
