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.
Sisal fibers are extracted from the Agave plant; the leaves of the plant are cut and then taken to a machine that splits them apart and extracts the sought after fiber (this process is called decortication). The fibers are then fluffed and brushed out before being washed and then left to dry for 24 hours.
