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]
Fiber (also spelled fibre in British English; from Latin: fibra) [1] is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials.
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.
The major constituents of natural fibers (lignocelluloses) are cellulose, hemicellulose, lignin, pectin and ash. The percentage of each component varies for each different type of fiber, however, generally, are around 60-80% cellulose, 5–20% lignin, and 20% of moisture, besides hemicellulose and a small percent of residual chemical components.
At one time it was the country's greatest export item and Russia produced about 80% of the world's fiber flax crop. [11] In December 2006, the General Assembly of the United Nations proclaimed 2009 to be the International Year of Natural Fibres in order to raise people's awareness of linen and other natural fibers.

One cup (138 grams) of cherries with pits contains about 87 calories, 22 grams of carbohydrates, 19 grams of natural sugar, 3 grams of fiber, 1.5 grams of protein and almost no fat.
Rayon is a classified as a semi-synthetic fiber, made with natural polymers. Monomers are the building blocks of polymers. Polymers in fibers are of two types: additive or condensation. Natural fibers, such as cotton and wool, have a condensation polymer type, whereas synthetic fibers can have either an additive or a condensation polymer type.
Switch to a healthy diet:Eating a diet rich in fruits, vegetables, and grains, along with adequate amounts of protein and fiber can help you feel stronger and fight off infections.
