The Agave plant is native to Mexico and Central America, where its fiber has been used since pre-Columbian times. Each leaf contains an average of approx. To knot the fiber, each fiber is separated and knotted to the end of another fiber manually. The fibers are also used for making nonwovens for the application, for example, in the automotive industry. Sisal pulp and paper – As sisal biomass contains a high proportion of cellulose its pulp is a substitute for wood fibres and adds bulk to paper and cardboard as well as being absorbent and having high fold endurance characteristics making it a high quality input for paper products. ... 2.2 The Sisal Leaf The plant is characterized by its leaves which grow to a length of over one metre and yield a long, creamy-white and very strong fibre. During sisal leaf decortications, only 2.7-7.3% of the leaf produces the fiber. When composted however the pH value rises. Pineapple fibre is extracted from the leaves of the pineapple plant in a similar way to the extraction of sisal fibre, the difference being that pineapple leaves are narrower and shorter than sisal leaves. The lifetime of the plant is about 7–10 years and on maturity the fibers are extracted from the leaves; each leaf has about 1000 fiber bundles of which only 4% is fiber (Mukherjee and Satyanarayana, 1984).

They have a roughly thickened-horseshoe shape and seldom divide during the extraction processes. As received sisal, banana, and naturally woven coconut sheaths underwent a surface treatment separately using NaOH. They are also prone to microbial attack when wet and degrade when exposed to heat, light and ultraviolet radiation. It is important in the manufacture of such items as matting, rough handbags, ropes, cordage, especially marine rope (where good resistance to sea water is needed), and carpeting. Sisal is produced in South America (e.g. G.H. Ongoing evaluation of the plant indicates that 75% of the energy produced could be distributed to rural homes and 25 percent used in sisal processing. Sisal, (Agave sisalana), plant of the family Asparagaceae and its fibre, the most important of the leaf fibre group. 19.2 shows some production stages in the cordage industry that generate residues of sisal. The sisal fiber and its composites have been reviewed by many researchers (Mishra et al., 2004; Joseph et al., 1999). Competition from synthetics has weakened demand for sisal in these traditional applications, however new consumer demands for natural fibres are expanding the markets for sisal in more high-value applications such as in paper, reinforcing composites and plastic composites. Residues from sisal extraction can be used for making biogas, pharmaceutical ingredients, and building material (Li et al., 2000). China is also a major producer and consumerMarket outlookSisal has a promising future not only because of the new uses of this fibre but also because of growing public awareness that natural fibres, like sisal, are environmentally friendly. Central American countries also produce small amounts of this fibre. World production is about 300,000 tonnes. Production and trade Sisal is cultivated for fibre in Angola, Brazil, China, Cuba,  Haiti, Indonesia, Kenya, Madagascar, Mozambique,  Mexico, South Africa. During processing, a further 10% of fibres are lost as residues. CIRCULAR 186, V. S. DEPARTMENT OF AGRICULTURE The peel is clamped between a wooden plank and knife and hand-pulled through, removing the resinous material. From Savastano Jr., H., Santos, S.F., Agopyan, V., 2009. Keywords: Composites, Leaf Spring, Natural Fibers, Sisal. It yields a stiff fibre used in making rope and various other products. tonnes sisal fibre for the year 2007, it means generation of 4.5 million m 3 of sisal decortications wastewater and 1,125,000 tonnes of solid sisal decortications residues, of which about 900,000 tonnes is sisal leaf decortications residues (SLDR), the rest being short fibres residues. Textile - A major use of the fibre is in buffing cloth – because sisal is strong enough to polish steel and soft enough not to scratch it.Sisal reinforcing composites- Sisal can substitute or enhance fibre-glass used to reinforce plastic in automobiles, boats, furniture, water tanks and pipes. Table 4.13. Sisal also continues to make the best material for dart boards. The fiber bundles can be as long as the leaf itself and show generally a diameter between 100 and 300 µm, but can be even more than 400 µm. Brazil has benefited from China's growing import demand. The growth of sisal for use in non-traditional markets indicates that sisal is becoming increasingly recognized as a valuable and diverse resource material. Environmental benefitsSisal is a renewable resource par excellence and can form part of the overall solution to climate change. The sisal plant and its products have proved, over centuries of natural and commercial production, that they can serve mankind as a sustainable renewable resource; the plant is used for cordage and for woven, pharmaceutical and building products. Sisal is a fiber yielding plant whose botanical name is Agave Sisalana. The biomass left after fibres have been removed represents as much as 98 percent of the plant, and most is now flushed away as waste. In Tanzania and Kenya sisal is predominantly a plantation crop, while production in Brazil is largely small-scale. Fig. Sisal (Agave sisalana) is a commonly used leaf fiber in agricultural, shipping, and industrial applications (Roul, 2009). 19.3.
