The second filament has a material different from that of the first filament.

A non-woven fabric composite and an article including the same are provided. The non-woven fabric includes an electrostatically treated meltblown non-woven fabric layer and a spunbond non-woven fabric layer on one or both sides thereof, and has a fine dust removal performance retention ratio, represented by Equation 1, of 80% or more:
Fine dust removal performance retention ratio (%)=(fine dust removal efficiency after accelerated aging treatment)/(fine dust removal efficiency before accelerated aging treatment)100[Equation 1]
wherein, in this equation, the fine dust is an aerosol containing sodium chloride dispersed in air, and the accelerated aging treatment refers to a case where the non-woven fabric composite is stored at a temperature of 70 C. for 3 days.

A mat structure includes a main body. The main body has a property of toughness. The main body includes a first face and a second face. The main body is formed with a cut line in a middle. The cut line is formed through cutting from the second face of the main body. The cut line has a depth that is smaller than a thickness of the main body. The main body is further provided with at least one surface layer. With the depth of the cut line being smaller than the thickness of the main body and the main body having a property of toughness, the main body can be folded without causing damage. Further, when a die cutter is applied to cut and make the cut line, an allowable tolerance range for the die cutter is enlarged.

There is provided a woven fabric that can suppress a thickness reduction due to abrasion even under high-load and high-speed sliding conditions, has an excellent tribological property when used as a sliding material, hardly causes play between members, and can be used by being bonded to the base material; and also provided a woven fabric and a sliding material in which at least one of warp yarns and weft yarns includes doubled and twisted yarns of fluororesin fibers and para-aramid fibers, and the roughness on at least one surface where the doubled and twisted yarns are exposed is 1150 m or less.
