SUBSTANCE: invention relates to a nonwoven fabric containing an agent for breaking up a liquid film used for an absorbent article. The nonwoven fabric contains one or more compounds selected from the following compound (C1) and the next compound (C2), and one or more components selected from the following components (D2) and (D3), where (C1) is a compound having a spreading coefficient of 15 mN/m or more and 50 mN/m or less on a liquid having a surface tension of 50 mN/m and a water solubility of 0 g or more and 0.025 g or less; and (C2) a compound having a spreading coefficient greater than 0 mN/m and 50 mN/m or less on a liquid having a surface tension of 50 mN/m, a water solubility of 0 g or more and 0.025 g or less, and an interfacial tension phases greater than 0 mN/m and 20 mN/m or less on a liquid having a surface tension of 50 mN/m; and (D2) a compound having a surface tension of 42 mN/m or more and 60 mN/m or less, consisting of a structure containing a hydrophilic group, wherein the structure containing a hydrophilic group includes a structure containing a polyoxyethylene group or a structure containing a block copolymer of a polyoxyethylene group and a polyoxypropylene group; and (D3) bis-methoxypropylamidoisodocosane or nonwoven fabric contains one or more compounds selected from the following compound (C1) and the following compound (C2-1); and the next component (D1); where component (D1) is soluble in water, and when component (D1) is immersed in water for 20 minutes to prepare a 2.5 wt% aqueous solution of component (D1), the foam height is 10 mm or more and 20 mm or less; (D1) a nonionic surfactant having an HLB value of 10 or more and 20 or less and a melting point of 10°C or more and less than 25 °C; (C2-1) a compound having a spreading coefficient greater than 10 mN/m and 50 mN/m or less on a liquid having a surface tension of 50 mN/m, a water solubility of 0 g or more and 0.025 g or less, and a surface tension at the interface the interface is greater than 0 mN/m and 20 mN/ m or less on a liquid having a surface tension of 50 mN/m and a melting point of -220 °C or more and 40 °C or less.

EFFECT: technical result consists in creating a nonwoven material having improved properties of preventing surface liquid leakage and reducing the amount of residual liquid.
