PROBLEM TO BE SOLVED: To obtain a wiping nonwoven fabric sheet excellent in the using touch and capable of surely adsorbing fine dusts without impregnating the sheet with a dust-adsorbing agent, by blending a base material comprising hydrophilic extrafine fibers and oleophilic extrafine fibers having prescribed fiber diameters, respectively, with a superextrafine fibers to form the coarse mesh fabric high in a void degree. SOLUTION: A base material comprising hydrophilic extrafine fibers 2a having a fiber diameter of 10-30μm, such as extrafine rayon fibers, preferably in an amount of 20-40% and oleophilic extrafine fibers 2b, such as extrafine polypropylene fibers, preferably in an amount of 30-50% is blended with superextrafine fibers 3 having a fiber diameter of 1-9μm preferably in an amount of 20-40% to form the coarse mesh-like sheet high in the void degree. |
