Flax
Description
Any plant of the genus Linum, especially Linum usitatissimum that is native to Europe. Flax plants are grown for both their fibers and seeds. Flax fibers are believed to be the first vegetable fiber used by man (about 5000 CBE). They have been found in prehistoric cave dwellings in Switzerland. Ancient Egyptian pictographs detail the process for making flax into cloth and linen mummy cloths have been found. By the 17th century, linen manufacturing was an important industry in Western Europe. The soft, flexible fibers are produced by retting the stem of the plant, then washing and cleaning the fibers. Flax fibers of thinner and longer than cotton, but the fiber tube has thicker walls resulting in a stronger thread. Additionally, flax fibers are used to make shoe thread, bookbinding thread, fish line, twine, and paper. Waste flax fibers are used in banknotes, cigarette covers, and writing paper. The seeds from the flax plant are used to produce linseed oil. Linseed oil is used for cooking and as a paint medium.
