PROBLEM TO BE SOLVED: To provide a non-woven fabric which can control that foreign matters or the like penetrate or break through the non-woven fabric and is suitable for packaging materials, wipers, decorative sheets such as wall paper, agricultural or civil engineering materials such as weed-preventing sheets, and separators for batteries. SOLUTION: This method for producing the non-woven fabric having excellent thrust resistance, characterized by dispersing modified cross-sectional synthetic fibers (1) in an amount of at least 10 mass % based on the total amount of all fibers in water to prepare the slurry, subjecting the slurry to a wet paper-making process by the use of a paper machine, or subjecting the slurry to the wet paper-making process by the use of the paper machine and then jetting high pressure water flows having the maximum water pressure of <=3 MPa on the prepared wet paper. Each of the modified cross section synthetic fibers (1) has two or more protuberances (4) each having a flat ratio (the length of the long side/the length of the short side) of at least 1. 2, wherein the long side (2) is the largest diameter portion of the cross section of each fiber, and the short side (3) is the largest diameter portion crossing the long side (2) in the cross section. |
