Ramie fibers consist of a very high proportion of pure cellulose. Therefore, treatment with iodine and sulfuric acid turns the fiber pure blue, but treating it with aniline sulfate gives no color. Treatment with zinc chlor-iodide reagent gives the fiber a blue color, while the fiber color is rose red when treated with calcium chlor-iodide [108].
