Abstract
Methods to modify an engaging surface of a fibrous landing layer of a mechanical fastener are generally disclosed, along with products made from the same. For instance, the engaging surface of the landing layer can be mechanically modified to increase the fuzziness of the layer, which allows more fibers to engage the other surface of the mechanical fastener. For example, the improved engaging surface of the landing layer can increase the shear resistance of a mechanical fastener comprising a foam layer and a landing layer.
