A sheet of loop material adapted to be cut into pieces to form loop portions for fasteners of the type comprising releasably engageable hook and loop portions, or to be incorporated into items such as disposable garments or diapers or into sheets of abrasives. The sheet of loop material includes a sheet of longitudinally oriented fibers having anchor portions and arcuate portions projecting in one direction away from the anchor portions, and a layer of thermoplastic backing material extruded onto the anchor portions to bond to the anchor portions and form at least a portion of a backing for the loop material. The thermoplastic backing material can also bond the sheet of fibers to a sheet of backing material.
