Methods for controlled application of adhesive and garments formed thereby
A method of manufacturing a garment is provided that includes applying an adhesive layer to a first ply and/or a second ply in a first amount in a first zone where structural support is desired and in a second amount in a second zone where breathability is desired; arranging the first and second plies with respect to one another so that the adhesive layer is therebetween; and activating the adhesive layer to secure the first and second plies to one another.
1. A method of manufacturing a garment, comprising:
providing a first ply of material and a second ply of material, the first ply and the second ply being shaped to form at least a portion of a garment;
applying an adhesive layer to at least one of the first ply or the second ply with the adhesive layer in powder form, the adhesive layer residing in a first zone and a second zone, wherein the adhesive layer in the first zone has a first thickness and a first weight per unit area, the adhesive layer in the second zone has a second thickness greater than zero thickness and a second weight per unit area, and applying the adhesive layer comprises scatter coating the adhesive layer in powder form;
arranging the first ply and the second ply with respect to one another so that the adhesive layer is disposed therebetween; and
activating the adhesive layer to secure said first ply and said second ply to one another.
2. The method of claim 1 , wherein the adhesive layer is continuous between the first zone and the second zone and transitions in thickness between the first zone and the second zone.
3. The method of claim 1 , wherein the first thickness is greater than the second thickness and the first weight per unit area is greater than the second weight per unit area.
4. The method of claim 1 , further comprising applying none of said adhesive layer to said first ply or said second ply in a third zone where flexibility is desired.
5. The method of claim 1 , wherein the adhesive layer in the first zone has a thickness of between about 0.002 inches and about 0.006 inches.
6. The method of claim 5 , wherein, said thickness is about 0.004 inches.
7. The method of claim 1 , wherein the adhesive layer in the second zone has a thickness at or under about 0.002 inches.
8. The method of claim 1 , wherein activating the adhesive layer comprises curing the adhesive layer.
9. A garment comprising:
a first ply;
a second ply; and
an adhesive layer comprising a powder adhesive, a plurality of different zones of said powder adhesive disposed in the plurality of different zones, wherein said adhesive layer adheres said first ply and second ply to one another, wherein said plurality of different zones comprises:
a first zone having a first thickness of said adhesive greater than zero thickness and a first weight per unit area of the powder adhesive, and
a second zone having a second thickness of said adhesive greater than zero thickness and a second weight per unit area of the adhesive.
10. The garment of claim 9 , wherein each zone of the plurality of different zones comprises a different thickness of the adhesive layer.
11. The garment of claim 10 , wherein the adhesive layer comprises a transition area positioned between the plurality of different zones, the adhesive is disposed continuously in the plurality of zones, and the transition area is contiguous with the first zone and the second zone.
12. The garment of claim 10 , wherein the second thickness is less than the first thickness, and the second weight per unit area is less than the first weight per unit area.
13. The garment of claim 10 , wherein:
the first thickness is in a range of about 0.002 inches to about 0.006 inches, and the
second thickness is greater than zero and less than about 0.002 inches.
14. The garment of claim 13 , wherein said first thickness is about 0.004 inches.
15. The garment of claim 10 , wherein the adhesive in the first zone has a weight of between about 20 g/m 2 and about 40 g/m 2 , and the adhesive in the second zone has a weight of about 40 g/m 2 .
16. The garment of claim 15 , wherein adhesive in the first zone has a weight of about 30 g/m 2 .
17. The garment of claim 9 , wherein the garment defines a brassiere, the first zone extends at least partially around and partially defining a lower periphery of a breast cup of the brassiere, and the second zone comprises a band portion of the brassiere.
18. The garment of claim 17 , wherein said breast cup comprises a portion of said first ply and a portion of said second ply, wherein a portion of the breast cup having the portion of said first ply and the portion of said second ply excludes adhesive.
19. The garment of claim 17 , wherein said first zone further extends along and at least partially defines a lower edge of the band portion.
20. The garment of claim 9 , further comprising a plurality of perforations extending through said adhesive layer.
