Disclosed is a polyester synthetic fiber treatment agent that contains a silicone (A), a silicone (B), a nonionic surfactant, an anionic ingredient, and optionally a silicone (C). The amount of the silicone (C) contained in the polyester synthetic fiber treatment agent is less than 10% by mass. The silicone (A) is a silanol-modified silicone with a number average molecular weight of not less than 50,000 but less than 200,000. The silicone (B) is a silane coupling agent having at least one functional group selected from the group consisting of a methoxy group, an ethoxy group, an amino group, and an isocyanate group but not including an epoxy group in the molecule. The silicone (C) is at least one selected from the group consisting of silicone resins, dimethyl silicones, and alkyl-modified silicones but excluding those corresponding to being the silicone (A).

A first layered product for extinguishing fire, including: a pair of substrates; and a fire-extinguishing agent-containing layer between the pair of substrates, the layer containing a fire-extinguishing agent component generating an aerosol, and a binder resin, in which a water vapor transmission rate the substrate is 12 g/m.sup.2/day or less, a second layered product, including: a fiber layer containing an organic fiber or an inorganic fiber having a high strength-heat resistance; and a resin layer, in which at least any one of the fiber layer and the resin layer contains a fire-extinguishing agent component generating an aerosol, or a third layered product, including: a pair of substrates; and a fire-extinguishing agent-containing layer between the pair of substrates, the layer containing a fire-extinguishing agent component generating an aerosol, and a binder resin, in which a water vapor transmission rate of the substrate is 15 g/m.sup.2/day or less.

A barrier fabric suitable as a backsheet for an underpad configured for a low air loss bed, in which the barrier fabric comprises a first nonwoven fabric including outermost spunbond layers and two or more fine-fiber containing nonwoven layers. Each of the nonwoven layers being treated with a non-fluorinated barrier coating (NFBC).
