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
【課題】 ホルマリンを発生させない不織布用水性組成物であって、ホルマリンの発生源となり得るバインダーを用いた場合と同等の成膜性を有し、熱圧着後の金属離型性および熱圧着後のフィルム弾性に優れ、および熱圧着前後における非変形性を有する不織布用水性組成物を提供する。【解決手段】 アクリルバインダーと、融点が50℃以上の離型剤のエマルジョンとを含む不織布用水性組成物であって、前記アクリルバインダーは、ガラス転移温度が−50℃〜+20℃であって、エポキシ基とカルボン酸基とを含み、カルボン酸基含有モノマー単位を20重量%未満含有し、エポキシ基含有モノマー単位を5重量%未満含有し、前記カルボン酸基含有モノマー単位と前記エポキシ基含有モノマー単位の重量比率が20:80〜95:5である。【選択図】 なし
