are rayon fibers natural
More Info: Though rayon may start out as a natural fiber, the chemicals through which it is processed transform it to a synthetic fiber. Natural fibers include those produced by plants, animals, and geological processes and can be classified according to their origin: 1  Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, ramie, sisal, bagasse, and banana. Rayon is neither an entirely natural fiber nor an entirely synthetic one. This is because the cellulose from which rayon is originally derived is a natural fiber, but rayon requires extensive synthetic processing to be done to the cellulose in its production. The cellulose is extracted from wood or cotton pulp, although wood pulp is most common. Six of these seventeen groups are made from natural material. They include rayon, acetate, glass fiber, metallics, rubber, and azion. The remaining eleven fabrics are synthesized solely from chemical compounds. They are nylon, polyester, acrylic, modacrylic, olefin, spandex, anidex, saran, vinal, vinyon, and nytril. Fiber classification in reinforced plastics falls into two classes: (i) short fibers, also known as discontinuous fibers, with a general aspect ratio (defined as the ratio of fiber length to diameter) between 20 to 60, and (ii) long fibers, also known as continuous fibers, the general aspect ratio is between 200 to 500. There are two main categories of man-made fibers: those that are made from natural products (cellulosic fibers) and those that are synthesized solely from chemical compounds (noncellulosic polymer fibers). Rayon is a natural-based material that is made from the cellulose of wood pulp or cotton. This natural base gives it many of the characteristics—low cost, diversity, and comfort—that have led to its popularity and success. Cellulose fibers are a subset of man-made fibers, regenerated from natural cellulose. The cellulose comes from various sources: rayon from tree wood fiber, Modal from beech trees, bamboo fiber from bamboo, seacell from seaweed, etc. Rayon is a fabric that has the pros of being comprised of natural materials, but its cons stem from its impuissant structure. Rayon has been inexpensively produced from the natural cellulose of plants as an alternative to silk for centuries. It is easily dyed, drapes well and is incredibly versatile. A bundle of optical fibers. Fiber or fibre (from the Latin fibra) is a natural or synthetic string used as a component of composite materials, or, when matted into sheets, used to make products such as paper, papyrus, or felt. Regular or viscose rayon is the most prevalent, versatile and successful type of rayon. It can be blended with man-made or natural fibers and made into fabrics of varying weight and texture. It is also highly absorbent, economical and comfortable to wear. Regular viscose rayon does have some disadvantages.
