A coated nonwoven product used to make engine hood insulation material is produced by a method which involves needle punching a carded, cross-lapped web, then calendering the resulting web and then applying a foam coating. Rotary screen printing is used to apply a dot pattern of an acrylic emulsion to the dried, foam-coated web. Thermoplastic and/or thermoset material is deposited onto the acrylic coating and excess material is removed by vacuum, leaving a corresponding dot coating pattern of said material. The coated web is heated using infrared energy before cooling, cold calendering and winding-up.

A production process which provides advantages in terms of cost, lightness and health (carcinogenic effect) in the process of combining the two layers of the engine hood insulator positioned on internal combustion vehicles.
