The present invention relates to anti-static lightweight nonwoven fabric of ultrafine fibers for a dust collecting filter, capable of effectively removing static generated by fine dust and electrificating particles contained in the fine dust, wherein the anti-static nonwoven fabric of ultrafine fibers for a dust collecting filter has a triple layered structure where a scrim and a reversed layer are integrated by needle punching in a weight ratio of 0.25-0.65:0.3-0.7:1 with respect to a surface layer in which 95-98 wt% of polyester fiber of 0.7-0.8 denier and 2-5 wt% of metal fibers of 1-2 denier are mixed. The metal fiber of the surface layer is made up of stainless steel fibers. The scrim is woven from polyester of 300-500 denier and stainless steel yarn, wherein the stainless steel yarn is included as a part of weft or warp. In the reversed layer, 2-5 wt% of metal fiber of 1-2 denier made up of stainless steel fiber is mixed with respect to 98-95 wt% of polyester fiber of 2-3 denier. |
