| 摘要 |
A composite water-vapour-permeable fabric used in garments, footwear, hats, gloves, etc., comprises a laminate of a sheet of expanded polytetrafluoroethylene (PTFE) membrane (2) and a layer of non-expanded porous PTFE (4) formed thereon. The non-expanded PTFE is preferably a sintered network of granular-type PTFE particles fused together and formed in situ on the expanded PTFE membrane. |
