| 摘要 |
A porous belt or filter cloth comprises a woven or nonwoven textile substrate (11), which is coated on at least one surface with a coagulated polymer layer (12). The layer (12) preferably substantially impregnates the substrate, and the textile substrate, if nonwoven, may be supported on a mesh membrane (23), or a spiral link fabric (32). Alternatively, a layer of sintered particles (42) may be incorporated over the substrate which is covered by and impregnated by the coagulated polymer layer. |
