Bast fibre (fiber) or skin fibre is fibre collected from the Phloem (the "inner bark" or the skin) or bast surrounding the stem of a certain mainly dicotyledonic plant. Most of the technically important bast fibers are botained from herbs cultivated in agriculture, as for instance flax, hemp or rhamie, but also bast fibers from wild plants, as stingin nettel, 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 seprated from the xylem material ("woody core"), and somtimes also from epidermis. The process for this is called retting, and can be perfomred my 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 occure in bundels that are glued together by pectin and calcium ions. More intense retting separate the bfiber bundels into elemntary fibers, that can be several cm long. The bast fibres have often higher tensile strength than other kinds, and are therefore used for textiles (not seldom very excusive textiles, sometimes in blends with cotton or synthetic fibers) ropes, yarn, paper, composites and burlap. A special property with bast fibers are that the fiber contain a special strucuture, the fiber node, that represents a weak point. Fibernodes seems not to be present in seed hairs as cotton. For the meaning of fiber in nutrition, see dietary fiber. ... Bast are the strong fibers in the phloem of some plants. ...
