A high-strength non-woven fabric comprises 100 parts by weight of a non-woven fabric having an apparent fiber diameter of 0.1-15 mu m; and 0.3-10 parts by weight of an N-methylol or N-alkoxymethyl nylon resin applied to the non-woven fabric, the N-methylol or N-alkoxymethyl nylon resin being cross-linked. The high-strength non-woven fabric has high mechanical strength with small maximum pore diameter. It is suitable for battery separators.
