Most of the technically important bast fibers are obtained from herbs cultivated in agriculture, as for instance flax, hemp or rhamie, but also bast fibers from wild plants, as stinging nettle, and trees as the lime tree, have been used to some extent. Since the valuable fibers are located in the phloem, they must often be separated from the xylem material ("woody core"), and sometimes also from epidermis. The process for this is called rettingRetting Retting is a stage in the manufacturing of vegetable fibers, especially the bast fibers.... , and can be performed by microoganisms either on land (nowadays the most important) or in water, or by chemicals (for instance high pH and chelating agents) or by pectinolytic enzymes. In the phloem bast fibers occur in bundles that are glued together by pectin and calcium ions. More intense retting separate the fiber bundles into elementary fibers, that can be several cm long.
