11 Facts About Rayon

Rayon is a semi-synthetic fiber, made from natural sources of regenerated cellulose, such as wood and related agricultural products.

Rayon production involves solubilizing cellulose to allow turning the fibers into required form.

Rayon is produced by dissolving cellulose, then converting this solution back to insoluble fibrous cellulose.

Rayon was produced only as a filament fiber until the 1930s when methods were developed to utilize "broken waste rayon" as staple fiber.

Rayon fabrics are soft, smooth, cool, comfortable, and highly absorbent, but they do not always insulate body heat, making them ideal for use in hot and humid climates, although making their "hand" cool and sometimes almost slimy to the touch.
