The principal chemical component of vegetable fibers is cellulose, with varying amounts of lignin and hemicelluloses also usually present; thus, the fibers are also referred to as cellulosic or lignocellulosic. Examples include cotton, hemp, jute, flax, ramie, sisal, bagasse, and banana. Vegetable fibers are usually stiffer but less tough than synthetic fibers.
