Appl. No.:

11/463122

Inventors:

Jayshree Seth - Woodbury MN, US
Katherine A. Graham - Roseville MN, US
Brandy S. Nolan - Austin TX, US

Assignee:

3M Innovative Properties Company - Saint Paul MN

International Classification:

B32B 3/26

US Classification:

428 80, 428172, 4281951, 428201

Abstract:

There is provided an elastic laminate of a base layer with one or more attached elastic elements forming an elastic region. The elastic region width varies from a terminal end of the elastic tab to a proximal end of the elastic tab such that a width adjacent the terminal end is 20 to 80 percent narrower than a width adjacent the proximal end. The elastic region is defined by a plurality of segments, having differing average widths in the length direction of the elastic tab elastic region. The one or more elastic elements vary in one or more properties such that a plurality of the segments having different widths have substantially the same degree of elongation at a given elongation of the shaped elastic tab laminate.

International Classification:

B32B003/06

US Classification:

428/100000

Abstract:

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.

International Classification:

B32B003/26

US Classification:

428/315700, 428/316600, 428/100000

Abstract:

The invention is directed in part to an article that includes a polymer foam having a surface with surface microstructures, the surface microstructures have at least one extent or dimension of about 10 microns or more, preferably 50 microns or more. A maximum extent (unless it is a continuous rib-like structure) the microstructure is about 300 microns or less, preferably 200 microns or less, and generally a maximum height of 1000 microns or less, preferably 750 microns or less and a minimum height of 200 microns or more, preferably 300 microns or more. The foamed article may be provided in a variety of shapes, including a rod, a cylinder, a sheet, etc. In a preferred embodiment where the foam is provided in the form of a sheet, the foam has a pair of major surfaces, one or both of which can be provided with surface microstructures. The foam backing and microstructures include a plurality of voids, which voids are preferably of a mean size substantially less than the smallest cross-sectional dimension or extent of the microstructures.
