Abstract
Abstract The present invention provides a composite elastic necked-bonded material including at least one necked material joined to at least one elastic sheet. The composite elastic necked-bonded material is stretchable in a direction generally parallel to the direction of constriction or necking of the necked material. Also disclosed is a method of producing a composite elastic necked-bonded material by necking a neckable material and then joining the necked material to an elastic sheet.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
55 words
A method of producing a composite elastic necked-bonded material comprising: providing at least one neckable nonelastic material; applying a tensioning force to the neckable nonelastic material to neck said material; superposing the necked nonelastic material on an elastic sheet; and joining said tensioned, necked nonelastic material and said elastic sheet at least at two places.
Claim 2
Independent Claim
55 words
A method of producing a composite elastic necked-bonded material comprising: providing at least one neckable nonelastic material; applying a tensioning force to the neckable nonelastic material to neck said material; superposing the necked nonelastic material on an elastic sheet; and joining said tensioned, necked nonelastic material and said elastic sheet at least at two places.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein said elastic sheet is an elastic web of meltblown fibers.
Claim 4
Dependent Claim
49 words
The method of claim 1 wherein said elastic sheet comprises an elastomeric polymer selected from the group consisting of elastic polyesters, elastic polyurethanes, elastic polyamides, and elastic A-B-A' block copolymers wherein A and A' are the same or different thermoplastic polymer, and wherein B is an elastomeric polymer block.
Claim 5
Dependent Claim
12 words
The method of claim 2 wherein said meltblown fibers includes meltblown microfibers.
Claim 6
Dependent Claim
24 words
The method of claim 1 wherein said neckable material is a material selected from the group consisting of knitted fabrics and loosely woven fabrics.
Claim 7
Dependent Claim
45 words
The method of claim 1 wherein said neckable material is a web selected from the group consisting of a bonded carded web of fibers, a web of spunbonded fibers, a web of meltblown fibers, and a multilayer material including at least one of said webs.
Claim 8
Dependent Claim
21 words
The method of claim 6 wherein said fibers comprise a polymer selected from the group consisting of polyolefins, polyesters, and polyamides.
Claim 9
Dependent Claim
29 words
The method of claim 7 wherein said polyolefin is selected from the group consisting of one or more of polyethylene, polypropylene, polybutene, ethylene copolymers, propylene copolymers, and butene copolymers.
Claim 10
Dependent Claim
38 words
The method of claim 8 wherein said neckable material is a composite material comprising a mixture of fibers and one or more other materials selected from the group consisting of wood pulp, staple fibers, particulates and super-absorbent materials.
Claim 11
Dependent Claim
12 words
The method of claim 6 wherein said meltblown web includes meltblown microfibers.
Claim 12
Dependent Claim
18 words
The method of claim 1 wherein said elastic sheet is formed directly on said tensioned, necked nonelastic material.
Claim 13
Independent Claim
121 words
A method of producing a composite elastic necked-bonded material comprising: providing at least one neckable nonelastic nonwoven web selected from the group consisting of a bonded carded web of fibers, a web of spunbonded fibers, a web of meltblown fibers, and a multilayer material including at least one of said webs; applying a tensioning force to the neckable nonelastic nonwoven web to neck said material; superposing the necked material on a pressure sensitive elastomer adhesive sheet; and joining said tensioned, necked material and said pressure sensitive elastomer adhesive sheet by winding them together onto a wind-up roll so that the tensioning force from said necked material activates the pressure sensitive elastomer adhesive sheet and bonds the necked material to the sheet.
Claim 14
Independent Claim
121 words
A method of producing a composite elastic necked-bonded material comprising: providing at least one neckable nonelastic nonwoven web selected from the group consisting of a bonded carded web of fibers, a web of spunbonded fibers, a web of meltblown fibers, and a multilayer material including at least one of said webs; applying a tensioning force to the neckable nonelastic nonwoven web to neck said material; superposing the necked material on a pressure sensitive elastomer adhesive sheet; and joining said tensioned, necked material and said pressure sensitive elastomer adhesive sheet by winding them together onto a wind-up roll so that the tensioning force from said necked material activates the pressure sensitive elastomer adhesive sheet and bonds the necked material to the sheet.
Claim 15
Dependent Claim
26 words
The method of claim 12 wherein the pressure sensitive elastomeric adhesive nonwoven web of meltblown fibers is formed directly on the tensioned, necked nonelastic nonwoven web.
Claim 16
Dependent Claim
