Rayon While rayon is man-made, it is not considered a synthetic fiber, but a manufactured regenerated cellulosic fiber. Made from cellulose, rayon is a very versatile fiber and exhibits the same comfort properties as other natural fibers. It can imitate the feel and texture of silk, wool cotton and linen. The fibers are easily dyed in a wide range of colors. Rayon drapes well, has a soft, silky hand, and has a smooth, napped, or bulky surface. Rayon is highly absorbent but does not insulate body heat, hence making rayon garments ideal for use in hot and humid climates. The durability and appearance retention of regular rayon are low and will wrinkle easily and may stretch when wet and shrink when washed. Rayon also has the lowest elastic recovery of any fiber.
