| 摘要 |
The invention concerns a laminate for use in a garment for a clean room environment where formation of static charge on clothing worn by a worker in the clean room may deleteriously affect work being conducted therein. The laminate has a high rate of water vapour transmission, thus providing a comfortable garment, blocks transmission of bacteria and submicron size particles, sheds particles, and does not form particles itself. The laminate comprises a layer of porous polymeric film and adhesively bonded to it an electrically conductive textile fabric capable of dissipating static electric charge. The preferred porous polymer layer is of expanded polytetrafluoroethylene. The preferred electrically conductive textile fabric has a sufficient content of fibres containing electrically conductive carbon particles to dissipate static electric charges. |
