ABSTRACT:
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 SiO2or SnO2or a combination/mixture of the two substances, and such coating is hard and is superior in protection against contamination.
