The burning test for rayon involves holding a small piece of the fiber to a flame. Rayon will ignite easily and burn rapidly, producing a bright flame and a smell similar to burning paper. The chemical test for rayon can include dissolving it in sodium hydroxide, which will cause rayon to disintegrate, as it is a regenerated cellulose fiber. Both tests help differentiate rayon from other fibers, such as polyester or acrylic, which have different burning and solubility characteristics.
