PROBLEM TO BE SOLVED: To provide an aqueous composition for nonwoven fabric without generating formalin, having deposition property equal to the case with using a binder capable of becoming a generation source of formalin, excellent in metal mold releasability after thermal compression bond and film elasticity after the thermal compression bond and having non-deformation property before and after the thermal compression bond.SOLUTION: There is provided an aqueous composition for nonwoven fabric containing an acryl binder and an emulsion of a mold release agent having the melting point of 50°C or more, where the acryl binder has glass transition temperature of -50°C to +20°C, contains an epoxy group and a carboxylic acid group, a carboxylic acid group-containing monomer unit of less than 20 wt.% and an epoxy group-containing monomer unit of less than 5 wt.% and weight ratio of the carboxylic acid group-containing monomer unit and the epoxy group-containing monomer unit is 20:80 to 95:5.SELECTED DRAWING: None |
