Nature Fiber - Sisal 苎麻

Sisal fiber is obtained from Agave sisalana, a native of Mexico. The hardy plant grows well in a variety of hot climates. Including dry areas unsuitable for other crops. After harvest, its leaves are cut and crushed in order to separate the pulp from the fibers.

.

Sisal is used in twine and ropes, but competition from polypropylene has weakened demand.

.

But other markets are emerging. Today, sisal can be found in speciality paper, filters, geotextiles, mattresses, carpets, and wall coverings.

.

It is used as reinforcement in plastic composite materials, particularly in automotive components, but also in furniture. Another promising use is as a substitute for asbestos in brake pads. It is also the best material for making dartboards.

.

By-products from sisal extraction can be used for making bio-gas, pharmaceutical ingredients and building material.

.

Sisal is cultivated for fiber in Brazil, China, Cuba, Kenya, Haiti, Madagascar, and Mexico. Production patterns differ between countries. In Tanzania and Kenya, sisal is predominantly a plantation crop, while production in Brazil is largely small-scale.

.

World production of sisal and a similar agave fiber, henequen ( from Agave fourcroydes ) is estimated around 300,000 tonnes. The major producers are Brazil, Tanzania and Kenya.
