<p>Provided is a dust collector filter cloth that provides both high dust trapping efficiency and low pressure loss, and has excellent durability. The dust collector filter cloth (1) has a fibrous filter cloth base material (10), and a microfiber layer (20) formed on a filtering surface (10a) side of the filter cloth base material (10) by microfibers (21) that are finer than the fibers of the filter cloth base material (10). The microfiber layer (20): is formed on the inside of the filter cloth base material (10) on the filtering surface (10a) side (i.e., the inside of a web layer (12)), or to the inside of the fibrous filter cloth base material (10) from the filtering surface (10a); has a finer network structure than the filter cloth base material (10); and functions as a surface filtration layer. The microfiber layer (20) is capable of reducing pressure losses due to being thinly formed only on the filtering surface (10a) side. Furthermore, the microfiber layer (20) is capable of improving the trapping efficiency of fine dust due to pore diameter, and is capable of both improving dust trapping efficiency and reducing pressure losses.</p> |
