Abstract
A mechanical fastener is disclosed. The mechanical fastener generally comprises the male component of a hook and loop fastening system. The male component contains a plurality of protrusions that have been surface modified. In particular, the protrusions have been surfaced modified in a manner that prevents damage to a female component during engagement and disengagement but yet still forms a firm attachment with the female component.

A mechanical fastener comprising:
- a backing material;
- a plurality of protrusions extending from the backing material, the protrusions being formed from a polymeric material;
- wherein each protrusion has an outer surface;
- wherein at least a portion of the outer surface of the protrusions have been modified in an amount sufficient to decrease surface forces between the outer surfaces of the protrusions and a corresponding material, that has not been modified, during engagement and disengagement between the protrusions and the material.
