Abstract
Abstract Laminate sheet materials having outer fabric layers and an intermediate non-woven fiberfill layer are provided, which are particularly suitable for use in making molded, one-piece, bra cups. The sheet materials are uniformly pre-shrunk, and include fabric outer layers that are securely rather than lightly bonded to an intermediate fiberfill layer by amounts of adhesive that substantially penetrate the intermediate layer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
A laminate composition suitable for molding into one-piece bra cups, comprising oppositely disposed outer fabric layers and an intermediate fiberfill layer of non-woven staple fibers disposed therebetween, said layers being held together with a separate and distinct adhesive composition which substantially penetrates said intermediate layer to securely bond said outer fabric layers to said intermediate fiberfill layer, said outer fabric layers and said intermediate fiberfill layer comprising fiber materials which shrink at approximately the same rate upon application of heat and pressure.
Claim 2
Dependent Claim
82 words
A laminate composition suitable for molding into one-piece bra cups, comprising oppositely disposed outer fabric layers and an intermediate fiberfill layer of non-woven staple fibers disposed therebetween, said layers being held together with a separate and distinct adhesive composition which substantially penetrates said intermediate layer to securely bond said outer fabric layers to said intermediate fiberfill layer, said outer fabric layers and said intermediate fiberfill layer comprising fiber materials which shrink at approximately the same rate upon application of heat and pressure.
Claim 3
Dependent Claim
21 words
The laminate composition of claim 1 wherein said laminate composition is uniformly pre-shrunk prior to complete drying of said adhesive composition.
Claim 4
Dependent Claim
37 words
The laminate composition of claim 1 wherein said adhesive composition penetrates said intermediate layer to a depth of between about 1/3 and 1/2 the overall thickness of said intermediate layer on each side of said intermediate layer.
Claim 5
Dependent Claim
48 words
The laminate composition of claim 3 wherein said outer fabric layers comprise polyester fibers having deniers in the range of about 20 to 70, and said intermediate fiberfill layer comprises random, non-woven, staple polyester fibers having average fiber lengths in the range of about 1 to 2 inches.
Claim 6
Dependent Claim
21 words
The laminate composition of claim 1 wherein said adhesive composition is an aqueous dispersion or emulsion of a carboxylic acrylic polymer.
Claim 7
Dependent Claim
12 words
A molded bra cup made from the laminate composition of claim 1.
Claim 8
Dependent Claim
121 words
A laminate composition suitable for molding into one-piece bra cups, comprising a first outer fabric layer and an intermediate fiberfill layer of non-woven staple fibers secured to said outer fabric layer, said layers being held together with an adhesive composition which penetrates said intermediate layer to a depth of between about 1/3 and 1/2 the overall thickness of said intermediate layer, said outer fabric layer comprising polyester fibers having deniers in the range of about 20 to 70, and said intermediate fiberfill layer comprising random, non-woven, staple polyester fibers having average fiber lengths in the range of about 1 to 2 inches, whereby upon application of heat and pressure said fabric layer and fiberfill layer shrink at approximately the same rate.
Claim 9
Dependent Claim
121 words
A laminate composition suitable for molding into one-piece bra cups, comprising a first outer fabric layer and an intermediate fiberfill layer of non-woven staple fibers secured to said outer fabric layer, said layers being held together with an adhesive composition which penetrates said intermediate layer to a depth of between about 1/3 and 1/2 the overall thickness of said intermediate layer, said outer fabric layer comprising polyester fibers having deniers in the range of about 20 to 70, and said intermediate fiberfill layer comprising random, non-woven, staple polyester fibers having average fiber lengths in the range of about 1 to 2 inches, whereby upon application of heat and pressure said fabric layer and fiberfill layer shrink at approximately the same rate.
Claim 10
Dependent Claim
31 words
A molded bra cup made from the laminate composition of claim 7 wherein a second outer fabric layer is secured to said intermediate fiberfill layer opposite said first outer fabric layer.
