Waterproof garment with invisible barrier seam
A waterproof invisible barrier seam is formed between two fabric laminates, an outer shell fabric laminate and an inner lining fabric laminate. The seam includes an invisible seam tape that forms a hydrostatic barrier within the seam. The design of the seam allows the formation of an effective hydrostatic barrier along the seams of a soft shell garment, while retaining flexibility, stretch, aesthetic appearance, and reversibility.
1. A textile product containing an invisible barrier fabric seam, comprising:
an outer garment, an inner garment, and a hydrophobic polymer membrane between the outer garment and the inner garment;
the hydrophobic polymer membrane including at least two pieces joined to form at least one seam disposed between the outer garment and the inner garment; and
a hydrophobic barrier across the at least one seam of the hydrophobic polymer membrane, the hydrophobic barrier comprising a continuous connection between surfaces of the hydrophobic polymer membrane across the at least one seam;
wherein the outer garment, the inner garment, and the hydrophobic polymer membrane are fused together over their surfaces areas to provide a laminated garment.
2. The textile product of claim 1 , wherein the hydrophobic barrier further comprises a seam tape comprising a single ply of an adhesive polymer, wherein the seam tape is disposed in alignment with the at least one seam of the hydrophobic polymer membrane, to provide a continuous hydrophobic barrier across the at least one seam.
3. The textile product of claim 1 , wherein the hydrophobic barrier further comprises a seam tape comprising a further hydrophobic polymer membrane layer and an adhesive layer on one side of the hydrophobic polymer membrane layer, wherein the seam tape is disposed in alignment with the at least one seam of the hydrophobic polymer membrane, and the adhesive of the seam tape is bonded to both the hydrophobic polymer membrane and the further hydrophobic polymer membrane layer of the seam tape to provide a continuous hydrophobic barrier across the at least one seam.
4. The textile product of claim 3 , wherein the seam tape includes a further adhesive layer on an opposite side of the hydrophobic polymer membrane layer, so that the hydrophobic polymer membrane layer is disposed between the adhesive layer and the further adhesive layer.
5. The textile product of claim 1 , wherein the hydrophobic polymer membrane comprises microporous or nanoporous polytetrafluoroethylene, expanded polytetrafluoroethylene, polyurethane, cross-linked polyurethane, polypropylene, or polyester.
6. The textile product of claim 1 , wherein the hydrophobic polymer membrane further comprises a reinforcing layer, a membrane protective fabric, a tricot, or a scrim.
7. The textile product of claim 1 , wherein the outer garment comprises at least two garment pieces joined at the at least one seam of the hydrophobic polymer membrane.
8. The textile product of claim 1 , wherein the inner garment comprises at least two garment pieces joined at the at least one seam of the hydrophobic polymer membrane.
9. The textile product of claim 1 , wherein one or both of the outer garment and the inner garment comprises a fabric laminate.
10. The textile product of claim 1 , wherein one or both of the outer garment and the inner garment comprise a fabric coated with silicone, polyurethane, polyester, or polypropylene.
11. The textile product of claim 1 , wherein the inner garment comprises a tricot, scrim, fleece, or thermal insulating material.
12. The textile product of claim 1 , further comprising an insulation zone between the outer garment and the inner garment.
13. The textile product of claim 1 , wherein each of the outer garment and the inner garment are formed of at least two garment pieces joined at a seam, at least one of the seam joining the inner garment pieces and the seam joining the outer garment pieces aligned with the seam of the hydrophobic polymer membrane.
14. The textile product of claim 1 , wherein each of the outer garment and the inner garment are formed of at least two garment pieces joined at a seam, at least one of the seam joining the inner garment pieces and the seam joining the outer garment pieces offset from the seam of the hydrophobic polymer membrane.
15. The textile product of claim 1 , wherein the product is selected from the group consisting of jackets, coats, parkas, raincoats, cloaks, ponchos, shirts, blouses, pants, vests, capes, gloves, hats, hoods, headwear, shoes, boots, socks, and undergarments.
16. The textile product of claim 1 , wherein the product is a reversible garment.
