A fiber sheet composed of knitted, woven, or non-woven fiber, which is resistant against contamination, and such contamination is easily washed off, and is durable, and suitable for use as materials to make curtains, tapestries, screens, flags, wallpaper, and sliding screen door (fusuma), for both indoor and outdoor environments. The fiber sheet is coated on its both sides of the fiber by ceramics composed of oxidized, nitrogenous, or carbonized forms of metals such as tin, titanium, aluminum, and other metals, forming a thin contamination resistant coating. Typically, the contamination resistant coating comprises SiO2 or SnO2 or a combination/mixture of the two substances, and such coating is hard and is superior in protection against contamination.

What is claimed is: 1. A contamination resistant fiber sheet comprising: a vapor deposited contamination resistant ceramic coating disposed on a front and a back side of the fiber sheet, wherein a breathable, water-repellent undercoating is disposed on the front side of the fiber sheet underneath the contamination resistant coating, wherein the ceramic coating is of sufficient thickness to inhibit adherence of contaminants to the fiber sheet and wherein the coated fiber sheet coating comprises a mixture of SiO2 and SnO2 having a thickness between 1-500 nm and exhibits a tactile feel analogous to an uncoated fiber, and wherein the fiber sheet is used for curtains, tapestry, heavy curtains, flags, wall paper, or shoji paper. 2. The contamination resistant fiber sheet as claimed in claim 1, wherein the contamination resistant ceramic coating has a thickness between 1-200 nm. 3. The contamination resistant fiber sheet as claimed in claim 1, wherein the contamination resistant fiber sheet is hydrophilic. 4. The contamination resistant fiber sheet as claimed in claim 1, wherein the contamination resistant ceramic coating is transparent to allow designs or patterns on the fiber sheet to be viewable. 5. The contamination resistant fiber sheet as claimed in claim 1, wherein the fiber sheet comprises knitted, woven, or non-woven fiber. 6. The contamination resistant fiber sheet as claimed in claim 1, wherein the fiber sheet comprises synthetic fiber material. 7. The contamination resistant fiber sheet as claimed in claim 1, wherein the contamination resistant ceramic coating is applied by vacuum vapor deposit, sputter vapor deposit, ion beam deposit or ion plating. 8. The contamination resistant fiber sheet as claimed in claim 1, wherein the contamination resistant ceramic coating comprises a non-continuous amorphous structure. 9. The contamination resistant fiber sheet as claimed in claim 6, wherein the synthetic fiber material is nylon fiber, polyester fiber, polyacrylonitrile fiber, or aramid fiber.
