There are more than 40 species of jute that are found all over the world. Out of these, eight species are cultivated commercially for producing fibre. Of these eight, two species Corchorus capsularis L and Corchorus olitorius L belonging to the Tiliaceae family, are more widespread in India. Jute fibre is extracted from the bark of the stem of these commercial species of jute. The fibre of Olitorius is finer, stronger and more lustrous than that. The fibre of Olitorius is yellowish and that of Capsularis is white, thus they are called White jute and Tossa jute respectively.
