A fibrous blanket material is provided having a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof and a layer of meltblown polypropylene fibers. In an alternative embodiment the blanket may also include a second fibrous layer made of the same material as the first layer where the layer of meltblown polypropylene fibers is sandwiched between the two fibrous layers.

What is claimed is: 1. A fibrous blanket material, comprising: a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof wherein said fibers have an average diameter of between about 10.0 and about 30.0 microns and a thickness of between about 0.5 and about 8.0 cm; and a layer of meltblown polypropylene fibers having a thickness of between about 0.0127 to about 0.254 cm wherein said first fibrous layer and said layer of meltblown polypropylene fibers are bonded together by means of heat, spray adhesive or both. 2. A fibrous blanket material, comprising: a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof wherein said fibers have an average diameter of between about 10.0 and about 30.0 microns and a density of between about 0.5 and about 8.0 lbs/ft3; and a layer of meltblown polypropylene fibers having a thickness of between about 0.0127 to about 0.254 cm wherein said first fibrous layer and said layer of meltblown polypropylene fibers are bonded together by means of heat, spray adhesive or both. 3. A fibrous blanket material, comprising: a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof wherein said fibers have an average diameter of between about 10.0 and about 30.0 microns; a layer of meltblown polypropylene fibers; and a second fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof, wherein said layer of meltblown polypropylene fibers is sandwiched between said first and second fibrous layers wherein said first fibrous layer, said layer of meltblown polypropylene fibers and said second fibrous layer are bonded together by heat, spray adhesive or both; said first fibrous layer having a thickness of between about 0.5 and about 5.0 cm, said layer of meltblown polypropylene fibers having a thickness of between about 0.0127 and about 0.254 cm and said second fibrous layer having a thickness of between about 0.5 and about 5.0 cm. 4. The fibrous blanket material of claim 3, wherein said layer of meltblown polypropylene fibers has a weight of between about 0.5 to about 10.0 ounces/sq. yard. 5. The fibrous blanket material of claim 3, wherein said layer of meltblown polypropylene fibers has a weight of between about 0.5 to about 3.0 ounces/sq. yard. 6. The fibrous blanket material of claim 3, wherein said meltblown polypropylene fibers have an average diameter of between about 2.5 to about 50.0 microns. 7. The fibrous blanket material of claim 3, wherein said meltblown polypropylene fibers have an average diameter of between about 5.0 to about 25.0 microns. 8. A fibrous blanket material, comprising: a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof having an average fiber diameter of between about 10.0 and about 30.0 microns, a density of between about 0.5 and about 8.0 lbs/ft3 and a thickness of between about 0.5 and about 8.0 cm; and a layer of meltblown polypropylene fibers having a thickness of between about 0.0127 to about 0.254 cm, an average fiber diameter of between about 2.5 to about 50.0 microns and a weight of between about 0.5 to about 10.0 ounces/sq. yard wherein said first fibrous layer and said layer of meltblown polypropylene fibers are bonded together by means of heat, spray adhesive or both. 9. A fibrous blanket material, comprising: a first fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof; a layer of meltblown polypropylene fibers having an average fiber diameter of between about 2.5 to about 50.0 microns and a weight of between about 0.5 to about 10.0 ounces/sq. yard; and a second fibrous layer selected from a group of fibers consisting of polyester, polypropylene, polyethylene, fiberglass, natural fibers, nylon, rayon and blends thereof, wherein said layer of meltblown polypropylene fibers is sandwiched between said first and second fibrous layers wherein said first fibrous layer, said layer of meltblown polypropylene fibers and said second fibrous layer are bonded together by heat, spray adhesive or both; said first fibrous layer having a thickness of between about 0.5 and about 5.0 cm, said layer of meltblown polypropylene fibers having a thickness of between about 0.0127 and about 0.254 cm and said second fibrous layer having a thickness of between about 0.5 and about 5.0 cm.
