1 Absorbency: Rayon is the most absorbent of all cellulose fibers, even more so than cotton and linen. 2  Because of this, rayon absorbs perspiration and allows it to evaporate away from the skin, making it an excellent summer fabric. 3  Its high absorbency applies equally to dyes, allowing beautiful, deep, rich colours.
When a solution of cellulose in cuprammonium hydroxide comes into contact with sulfuric acid, the cellulose begins to precipitate from the solution. The sulfuric acid reacts with a complex compound of copper and dissolves it. Thin blue fibers of rayon are formed. After some time, sulfuric acid reacts with the complex compound and washes out the copper salts from the fibers. The fibers become colorless. Rayon is a manufactured regenerated cellulose fiber.
