The terms graphite and carbon fiber have become interchangeable to some extent. However, graphite in lead pencils and graphite in a tennis racket are obviously not the same material. The material that makes a strong racket is actually made of carbon fibers.
Dietary fiber is a plant-based nutrient that is sometimes called roughage or bulk. It is a type of carbohydrate but, unlike other carbs, it cannot be broken down into digestible sugar molecules. Therefore, fiber passes through the intestinal tract relatively intact.
So what exactly is the difference between marijuana and hemp? Let’s start with semantics. Hemp refers to strains of Cannabis sativa that have been bred specifically for fiber used for clothing and construction, oils and topical ointments, nutritional benefits and a wide and growing variety of other purposes that don’t involve intoxication.
Indian hemp, also called Hemp Dogbane, (species Apocynum cannabinum), North American plant of the dogbane family Apocynaceae (order Gentianales). It is a branched perennial that grows up to 1.5 m (5 feet) tall and has smooth opposite leaves and small greenish white flowers.
Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the Malvaceae family also called Deccan hemp and Java jute. Hibiscus cannabinus is in the genus Hibiscus and is native to southern Asia, though its exact origin is unknown. The name also applies to the fibre obtained from this plant.
Synthetic fibres have not dominated the market since the 1950s and 1960s. As of 2008, nylon continued to represent about 12% (8 million pounds) of the world’s production of synthetic fibres. Although pure nylon has many flaws and is now rarely used, its derivatives have greatly influenced and contributed to society.
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu.
Polypropylene fibre burns and presents much the same risks as most other man-made textile fibres. It is difficult to ignite, and is defined as combustible but not highly inflammable. It can, however, be rendered flame-retardant by the incorporation of additives.
Rayon is a manufactured regenerated cellulose fiber. It is made from purified cellulose, primarily from wood pulp, which is chemically converted into a soluble compound. It is then dissolved and forced through a spinneret to produce filaments which are chemically solidified, resulting in synthetic fibers of nearly pure cellulose.
Roselle, also called rosella, Jamaican sorrel, or java jute, (Hibiscus sabdariffa), plant of the hibiscus, or mallow, family , and its fibre, one of the bast fibre group. Roselle is probably native to West Africa and includes H. sabdariffa variety altissima, grown for fibre, and H. sabdariffa variety sabdariffa, cultivated for the edible external portion of its flower (calyx).
