PROBLEM TO BE SOLVED: To provide a curtain made of a disposable nonwoven fabric capable of trapping an aldehyde-based poisonous gas. SOLUTION: This curtain made of a nonwoven fabric is obtained by coating and impregnating a nonwoven fabric with an agent for trapping the aldehyde- based poisonous gas. The coating and impregnating of the trapping agent is carried out by dipping the nonwoven fabric in a 0.5-20% aqueous solution of the trapping agent, and drying the dipped nonwoven fabric. If necessary, the nonwoven fabric is dipped in an emulsion of a water-soluble resin (having 40-50% solid content) containing 0.5-5% above trapping agent, and the dipped fabric is subjected to predrying, and thereafter heat treatment to provide the objective nonwoven fabric.
