Abstract
A waterproof seam for a garment is formed between two pieces of fabric, at least one of the pieces being a laminate. The laminate comprises a first layer (40, 50) comprising a waterproof water-vapour-permeable layer, and a second knitted or woven layer (30) laminated to the first layer. The second layer (30) comprises a first component and a second component, the first component being stable to a first temperature and a second component melting at a second temperature lower than the first temperature. The seam also comprises a thermoplastic seam seal tape (5) in contact with the second layer of the at least one piece of laminate, and sealing the seam. The seam seal tape is applied over the seam at elevated temperature and pressure, so as to melt the thermoplastic seam seal tape and also the second component of the knitted or woven layer, and form a waterproof seam.
