Sisal (/ËsaÉªsÉl/ , [siËsal]), with the botanical name Agave sisalana, is a species of Agave native to southern Mexico but widely cultivated and naturalized in many other countries.t is sometimes referred to as sisal hemp, because for centuries hemp was a major source for fibre, and other fibre sources were named after it.
Traditionally sisal was the leading material for agricultural twine (binder and baler twine) but the importance of this has now diminished (with competition from polypropylene and other techniques) although there is still a major business between Brazil and the United States.raditionally sisal was the leading material for agricultural twine (binder and baler twine) but the importance of this has now diminished (with competition from polypropylene and other techniques) although there is still a major business between Brazil and the United States.
