Abstract: The present invention disclose a multi-layer waterproof seam (100) comprising a first component (10), and a second component (20); the first component (10) comprising a layer of outer shell fabric (15); and the second component comprising at least one layer of adhesive (25) disposed onto a layer of water barrier membrane (30); the said layer adhesive (25) permits fusion or bonding between the first component (10) and the second component (20).

Abstract: A seam comprising a first piece of laminated fabric, a second piece of laminated fabric, a layer of adhesive hydrostatic polymer, and a seam tape wherein the first and second pieces of laminated fabrics are coupled together at a common border with the layer of adhesive hydrostatic polymer to form a seam, and wherein the seam tape is at least partially coupled along the seam. A method of forming a seam comprising stacking, in order, a first piece of laminated fabric, at least one strip of adhesive hydrostatic polymer, and a second piece of laminated fabric, ultrasonically coupling the first piece of laminated fabric, strips of adhesive hydrostatic polymer, and second piece of laminated fabric together, wherein at least a portion of adhesive hydrostatic polymer from the strips of adhesive hydrostatic polymer is extruded through the seam, and applying a seam tape along at least a portion of the seam.

Abstract: A zip fastener (30) comprised of a long strip of two thermoplastic support tapes (35); two rows of coupling elements (40), each row being attached to its own support tape (35); and a slider body (45) comprising a puller (50) attached to the slider body (45). Portions of the two support tapes (35) are shaped to cause the two rows of coupling elements (40) to rest higher or lower than the shaped portions of the support tapes (35). At least one end portion of the zip fastener (30) is curved downward and in a closed position the curved portion (75) accommodates at least one slider body (45).

Abstract: A process of providing ventilation points on a flexible substrate includes treating the flexible substrate with a chemical or a combination of chemicals that react to an environmental factor; and using that reaction to the environmental factor to regulate functioning of the ventilation points prepared on the substrate. A ventilated substrate includes ventilation points in the substrate; and a chemical or combination of chemicals applied to the substrate that regulate the ventilation points in response to an environmental factor.
