Abstract

A laminated article having elastic strands or filaments contained therein for providing elasticity to the article, are provided. The particular adhesive pattern bonds the relatively inelastic nonwoven layers to the more elastic continuous filaments in a pattern that allows adhesive-to-adhesive, adhesive-to-nonwoven layer, and adhesive-to-elastic filament bonding.

Claims

1. An laminated fabric article comprising:

(a) a facing layer;

(b) a plurality of elastic filaments adjacent to a surface of the facing layer; and

(c) an adhesive component, wherein the adhesive component is applied to the surface of the nonwoven layer in adhesive lines, the adhesive lines intersecting both the elastic filaments and themselves to form a bonding network comprised of adhesive-to-elastic bonds, adhesive-to-facing layer, and adhesive-to-adhesive bonds.

2. The laminated fabric article of claim 1 wherein said adhesive lines intersect said elastic filaments at an angle of greater than 45°

and less than 90°

.

3. The laminated fabric article of claim 1 wherein said adhesive lines intersect said elastic filaments at an angle of between about 50°

and about 90°

.

4. The laminated fabric article of claim 1 wherein said adhesive lines intersect said elastic filaments at an angle of between about 60°

and about 90°

.

5. The laminated fabric article of claim 1 wherein said adhesive lines intersect said elastic filaments at an angle of about 60°

.

6. The laminated fabric article of claim 1 comprising an additional facing.

7. The laminated fabric article of claim 1 wherein said adhesive component is about 3 to about 5 gsm in weight.

8. The laminated fabric article of claim 1 wherein said article has a basis weight of between about 2 to about 4 osy.

9. The laminated fabric article of claim 1 wherein said facing layer comprises a spunbonded nonwoven web.

10. The laminated fabric article of claim 6 wherein said additional facing comprises a spunbonded nonwoven web.

11. The laminated fabric article of claim 6 wherein said continuous filaments and said adhesive component are between said facing layers.

13. The method of claim 12 further comprising the steps of:

providing a second facing layer and applying an adhesive component to said second facing layer to bond said elastic filaments to said facing layer in adhesive lines that intersect both the elastic filaments and themselves to form a bonding network comprised of adhesive-to-elastic bonds, adhesive-to-facing layer, and adhesive-to-adhesive bonds.

12. A method of manufacturing a laminated fabric article comprising:

(a) providing a facing layer;

(b) providing a plurality of elastic filaments adjacent to a surface of the facing layer; and

(c) applying an adhesive component to bond said elastic filaments to said facing layer in adhesive lines that intersect both the elastic filaments and themselves to form a bonding network comprised of adhesive-to-elastic bonds, adhesive-to-facing layer, and adhesive-to-adhesive bonds.
