Abstract:
1. A method of making a garment comprising an invisible barrier fabric seam, the method comprising the steps of: (a) providing an outer shell fabric laminate, an inner liner fabric, and a seam tape, the outer shell fabric laminate comprising a shell fabric and a hydrophobic polymer membrane, and the seam tape comprising an adhesive layer and a hydrophobic polymer membrane, wherein the hydrophobic polymer membrane of the seam tape is disposed adjacent to the adhesive layer; (b) cutting a plurality of outer garment pieces from the outer shell fabric laminate according to an outer garment pattern; (c) cutting a plurality of inner garment pieces from the inner liner fabric according to an inner garment pattern; wherein seam locations of the inner garment pattern overlap with seam locations of the outer garment pattern; (d) assembling one or more seams of an inner garment from the inner garment pieces and assembling one or more seams of an outer garment from the outer garment pieces; (e) attaching the seam tape to the outer shell fabric laminate along one or more of the assembled seams of the outer garment using heat or ultrasound energy, whereby the adhesive layer of the seam tape adheres to the hydrophobic polymer membrane of the outer shell fabric laminate; (f) aligning one or more of the assembled seams of the inner garment inside of the outer garment to form a composite garment, whereby the assembled seams of the inner garment are aligned with the seam tape attached to the outer garment; and (g) applying heat and/or pressure to one or more seams of the composite garment so as to seal the seams of the garment and join the inner and outer garments at one or more seams.
