Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. [1] Philippine natural fibers. Fiber crops are characterized by having a large concentration of cellulose, which is what gives them their strength. The fibers may be chemically modified, like in viscose (used to make rayon and ...
The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India.
Natural fibers are also used in composite materials, much like synthetic or glass fibers. These composites, called biocomposites, are a natural fiber in a matrix of synthetic polymers. [ 1 ] One of the first biofiber-reinforced plastics in use was a cellulose fiber in phenolics in 1908. [ 1 ]
Flax fiber is extracted from the bast beneath the surface of the stem of the flax plant. Flax fiber is soft, lustrous, and flexible; bundles of fiber have the appearance of blonde hair, hence the description "flaxen" hair. It is stronger than cotton fiber, but less elastic.

Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Cotton is the primary natural fibre used by humans today, amounting to about 80% of world natural fibre production. [5] Where cotton is cultivated, it is a major oilseed crop and a main protein source for animal feed.
Sisal (/ ˈ s aɪ s əl /, [2] Spanish:; Agave sisalana) is a species of flowering plant native to southern Mexico, but widely cultivated and naturalized in many other countries.It yields a stiff fibre used in making rope and various other products.
Mats made from woven abacá fibers from the Philippines. Due to its strength, it is a sought after product and is the strongest of the natural fibers. [11] It is used by the paper industry for such specialty uses such as tea bags, banknotes [32] and decorative papers. [11]
