1. A laminate comprising: (a) a first layer of a nonwoven fabric having a fire retardant additive applied thereto, wherein the nonwoven fabric is spunlace fabric; and (b) a second single layer containing a halogenated flame resistant polymeric film, wherein the film consists of one of polyvinyl chloride, polyvinyl bromide, and polyvinylidene chloride, wherein the laminate passes NFPA 701-1989, has at least 12.0 lbs of grab tensile according to INDA IST 110.3-92, and has a Suter hydrostatic head of at least 50 cm. 2. The laminate of claim 1, wherein the spunlace fabric comprises cellulose fibers and manmade fibers. 3. The laminate of claim 1, wherein the spunlace fabric comprises cellulose fibers and polyester fibers. 4. The laminate of claim 1, wherein the spunlace fabric comprises wood pulp fibers and polyester fibers. 5. A laminate comprising: (a) a first layer of a spunlace fabric containing cellulose and manmade fibers, the first layer having a fire retardant additive applied thereto; and (b) a second layer of a polyvinyl chloride film, wherein the laminate passes NFPA 701-1989, has at least 12.0 lbs of grab tensile according to INDA IST 110.3-92, and has a Suter hydrostatic head of at least 50 cm. 6. The laminate of claim 5, wherein said first and second layers are joined together by an adhesive. 7. The laminate of claim 5, wherein the laminate has a thickness ranging from about 0.001 to about 0.5 inches. 8. The laminate of claim 5, wherein the fire retardant additive is ammonium polyphosphate, ammonium dihydrogen phosphate, urea polyammonium phosphate, antimony trioxide, sodium antimonate, zinc borate, a zirconium oxide, a molybdenum oxide, a zirconium sulfide, or a molybdenum sulfide. 9. The laminate of claim 5, wherein the fire retardant additive is applied to the first layer at about 5 to about 45 percent by weight of the first layer. 10. A protective garment formed of the laminate of claim 5. 11. The laminate of claim 5, further comprising: a third layer of a polyethylene film. 12. A laminate comprising: a first layer of a nonwoven fabric having a fire retardant additive applied thereto, wherein the nonwoven fabric is chosen from spunlace fabrics, spunbond fabrics, resin bonded fabrics, thermal bonded fabrics, airlaid pulp fabrics, and stitchbonded fabrics; and a second layer of a halogenated polymeric film, wherein the laminate has a total thickness ranging from about 0.005 to about 0.05 inches.
