The present invention concerns an extrusion formed reticulated web, mesh or netting
including reticulated hook fasteners for use with hook and loop fasteners the polymer
netting comprising two sets of strands at angles to each other. The first set of
strands are a plurality of oriented (molecular orientation created by stretching)
strands extending in a first direction and are generally mutually parallel and
linear. The second set of strands are a plurality of substantially parallel strands
attached only to a first face of the first set of oriented strands. The first set
of oriented strands occupy a first planar cross-sectional area in the thickness
direction of the formed netting. Said second set of oriented strands occupy a second
planar cross-sectional area in the thickness direction of the formed netting. Preferably,
these first and second planar cross-sectional areas are substantially mutually
exclusive and are abutting. The polymer netting is preferably made by extruding
a thermoplastic resin through a die plate, which die plate is shaped to form a
base film layer and spaced ridges or ribs projecting from a surface of the base
layer. The spaced ridges or ribs formed by the die form the first set of strands
forming the reticulated mesh or netting. The second set of transverse strands are
formed by transversely cutting the base layer at spaced locations along a length,
at a transverse angle to the ridges or ribs, to form discrete cut portions. Subsequently
longitudinal stretching of the ridges (in the direction of the ridges or the machine
direction) separates these cut portions of the backing, which cut portion then
form the second set of spaced apart strands of the reticulated mesh or netting.
