Abstract
Official abstract text for this publication.
A radioprotective unwoven fabric is a sheet in which metal fibers are three-dimensionally and randomly stacked, the metal fibers each comprising a metal material having a specific gravity higher than a specific gravity of lead. The metal fibers may comprise a tungsten wire.
First claim
Opening claim text (preview).
What is claimed is: 1. A radioprotective unwoven fabric, which is a sheet in which metal fibers are three-dimensionally and randomly stacked, the metal fibers each comprising a metal material having a specific gravity higher than a specific gravity of lead, wherein the metal fibers make up the radioprotective unwoven fabric, and each of the metal fibers consists of metal wire. 2. The radioprotective unwoven fabric according to claim 1 , wherein the metal fibers comprise a tungsten wire. 3. The radioprotective unwoven fabric according to claim 2 , wherein the metal fibers further comprise a molybdenum wire. 4. The radioprotective unwoven fabric according to claim 1 , wherein the metal fibers are only tungsten wires. 5. The radioprotective unwoven fabric according to claim 1 , which is felt. 6. The radioprotective unwoven fabric according to claim 1 , wherein each of the metal fibers is not a monofilament. 7. The radioprotective unwoven fabric according to claim 1 , wherein each of the metal fibers has a diameter of at most 1 mm and a length of at least 20 mm and at most 80 mm. 8. A fiber product, which is obtained by sewing the radioprotective unwoven fabric according to claim 1 . 9. A radioprotective product, which is a quilt including a front cloth, a back cloth, and padding including metal fibers and disposed between the front cloth and the back cloth, wherein the metal fibers are three-dimensionally and randomly stacked, the metal fibers each comprise a metal material having a specific gravity higher than a specific gravity of lead, and the metal fibers are woolly and make up the radioprotective unwoven fabric, and each of the metal fibers consists of metal wire. 10. The radioprotective product according to claim 9 , wherein the metal fibers comprise a tungsten wire. 11. The radioprotective product according to claim 10 , wherein the metal fibers further comprise a molybdenum wire. 12. The radioprotective product according to claim 9 , wherein the metal fibers are only tungsten wires. 13. The radioprotective product according to claim 9 , wherein each of the metal fibers is not a monofilament. 14. The radioprotective product according to claim 9 , wherein each of the metal fibers has a diameter of at most 1 mm and a length of at least 20 mm and at most 80 mm.
