Laminate of nonwoven fabric having unique properties suitable especially for use as a recreational fabric in the manufacture of tents, outer garments, tarpaulins and the like. The laminate includes, as essential components, an outer spunbonded layer treated for resistance to ultraviolet radiation and intended as the exposure surface, an inner microporous meltblown layer, preferably densified for resistance to liquid strike-through, and, on the unexposed surface, another nonwoven layer treated for flame retardancy. The combination optionally includes additional pigments in the exposed surface layers for desired appearance as well as pigments and/or ultraviolet radiation resistance treatment in the inner meltblown layer. As additional options, further layers of meltblown or spunbonded nonwovens may be included to attain desired physical properties. The resulting material provides a unique combination having excellent properties for recreational fabric uses, especially water repellency, breathability, resistance to degradation by ultraviolet radiation and flame retardancy.

A pattern bonded nonwoven fabric having a basis weight in the range of from about 2.5 to 10 oz/yd2 with permeability, water repellency and flame retardant properties comprising, a multi-layer structure of thermoplastic polymer nonwoven fabrics including continuous filament outer layers having a basis weight of about 0.5 to 5 oz/yd2 each, and a microfibrous intermediate layer having a basis weight of about 0.5 to 2.0 oz/yd2, wherein the melting points of the thermoplastic polymers used for each layer are similar and wherein the properties of the fabric result from forming or treating the component layers prior to combination including imparting ultraviolet light radiation resistance to one outer layer and flame retardancy to the other outer layer.
