| 摘要 |
The present invention is directed to a protective outdoor fabric comprising one or more layers of fine denier spunbond filaments and at least one layer of barrier material, wherein said protective outdoor fabric has a significant barrier performance as measured by the hydrostatic head to barrier layer basis weight ratio being of about at least 4.9 cm/gsm. In the preferred practice of the present invention, first and second outer fabric layers are formed, each comprising continuous filament spunbond layers of thermoplastic fibers, with the size of the continuous filaments between about 0.7 and 1.2 denier, preferably less than or equal to 1 denier. The barrier layer preferentially comprises microfibers of finite length, wherein the average fiber diameter is in the range of about 1 micron to about 10 microns, and preferably between about I micron and 5 microns, said layers being consolidated into a composite fabric. |
