Linen

The word linen is of West Germanic origin and cognate to the Latin name for the flax plant, , and the earlier Greek (). This word history has given rise to a number of other terms in English, most notably line, from the use of a linen (flax) thread to determine a straight line. It is also etymologically related to a number of other terms, including lining, because linen was often used to create an inner layer for clothing, and lingerie, from French, which originally denoted underwear made of linen. == History ==

People in various parts of the world began weaving linen at least several thousand years ago. It was also recovered from Qumran Cave 1 near the Dead Sea. Early history The discovery of dyed flax fibers in a cave in Southern Caucasus, West Asia (modern-day country of Georgia) dated to 36,000 years ago suggests that ancient people used wild flax fibers to create linen-like fabrics from an early date. Fragments of straw, seeds, fibers, yarns, and various types of fabrics, including linen samples, dating to about 8,000 BC have been found in Swiss lake dwellings. Woven flax textile fragments have been "found between infant and child" in a burial at Çatalhöyük, a large settlement dating to around 7,000 BC. To the southeast, in ancient Mesopotamia, flax was domesticated and linen was produced. It was used mainly by the wealthier class of the society, including priests. The Sumerian poem of the courtship of Inanna mentions flax and linen. In ancient Egypt, linen was used for mummification and for burial shrouds. It was also worn as clothing on a daily basis; white linen was worn because of the extreme heat. For example, the Tarkhan dress, considered to be among the oldest woven garments in the world and dated to between 3482 and 3102 BC, is made of linen. Plutarch wrote that the priests of Isis also wore linen because of its purity. Linen was sometimes used as a form of currency in ancient Egypt. Egyptian mummies were wrapped in linen as a symbol of light and purity, and as a display of wealth. Some of these fabrics, woven from hand-spun yarns, were very fine for their day, but are coarse compared with modern linen. 's 4th-century maximum prices edict showing prices for three grades of linen across the Roman Empire The earliest written documentation of a linen industry comes from the Linear B tablets of Pylos, Greece. There are many references to linen throughout the Bible. material Middle Ages By the Middle Ages, there was a thriving trade in German flax and linen. The trade spread throughout Germany by the 9th century and spread to Flanders and Brabant by the 11th century. The Lower Rhine was a center of linen making in the Middle Ages. Flax was cultivated and linen used for clothing in Ireland by the 11th century. Evidence suggests that flax may have been grown and sold in Southern England in the 12th and 13th centuries. Textiles, primarily linen and wool, were produced in decentralized home weaving mills. Modern history Linen continued to be valued for garments in the 16th century and beyond. Specimens of linen garments worn by historical figures have survived. For example, a linen cap worn by Emperor Charles V was carefully preserved after his death in 1558. Among them was Louis Crommelin, a leader who was appointed overseer of the royal linen manufacture of Ireland. He settled in the town of Lisburn near Belfast, which is itself perhaps the most famous linen producing center throughout history; during the Victorian era the majority of the world's linen was produced in the city, which gained it the name Linenopolis. Although the linen industry was already established in Ulster, Louis Crommelin found scope for improvement in weaving, and his efforts were so successful that he was appointed by the Government to develop the industry over a much wider range than the small confines of Lisburn and its surroundings. The direct result of his good work was the establishment, under statute, of the Board of Trustees of the Linen Manufacturers of Ireland in the year 1711. Several grades were produced including coarse lockram. The Living Linen Project was set up in 1995 as an oral archive of the knowledge of the Irish linen industry, which was at that time still available within a nucleus of people who formerly worked in the industry in Ulster. The linen industry was increasingly critical in the economies of Europe in the 18th and 19th centuries. In England and then in Germany, industrialization and machine production replaced manual work and production moved from the home to new factories. The homespun movement encouraged the use of flax to make home spun textiles. Through the 1830s, most farmers in the northern United States continued to grow flax for linen to be used for the family's clothing. In the late 19th and early 20th centuries, linen was very significant to Russia and its economy. At one time it was the country's greatest export item and Russia produced about 80% of the world's fiber flax crop. == Uses ==

Many products can be made with linen, such as clothing, bed sheets, aprons, bags, towels (swimming, bath, beach, body and wash towels), napkins, runners, and upholstery. It is used especially in sailcloth and lent cloth, sewing threads, handkerchiefs, table cloth, sheets, collars, cuffs etc.. Today, linen is usually an expensive textile produced in relatively small quantities. It has a long staple (individual fiber length) relative to cotton and other natural fibers. Linen fabric has been used for table coverings, bed coverings and clothing for centuries. The significant cost of linen derives not only from the difficulty of working with the thread but also because the flax plant itself requires a great deal of attention. In addition, flax thread is not elastic, and therefore it is difficult to weave without breaking threads. Consequently linen is considerably more expensive to manufacture than cotton. The collective term "linens" is still often used generically to describe a class of woven or knitted bed, bath, table and kitchen textiles traditionally made of flax-based linen but today made from a variety of fibers. The term "linens" refers to lightweight undergarments such as shirts, chemises, waist-shirts, lingerie (a cognate with linen), and detachable shirt collars and cuffs, all of which were historically made almost exclusively out of linen. The inner layer of fine composite cloth garments (as for example dress jackets) was traditionally made of linen, hence the word lining. The uses for linen changed dramatically from the 1970s, when about 5% of linen produced was used for fashion fabrics, to the 1990s, when about 70% was for clothing textiles. Linen uses range across bed and bath fabrics (tablecloths, bath towels, dish towels, bed sheets); home and commercial furnishing items (wallpaper/wall coverings, upholstery, window treatments); apparel items (suits, dresses, skirts, shirts); and industrial products (luggage, canvases, sewing thread). In 2005 researchers were working on a cotton/flax blend to create new yarns to improve the feel of denim during hot, humid weather. Conversely, some brands such as 100% Capri specially treat the linen to look like denim. Linen fabric is one of the preferred traditional supports for oil painting. In the United States cotton is popularly used instead, as linen is many times more expensive there, restricting its use to professional painters. In Europe, however, linen is usually the only fabric support available in art shops; in the UK both are freely available, cotton being cheaper. Linen is preferred to cotton for its strength, durability and archival integrity. Linen is also used extensively by artisan bakers. Known as a couche, the flax cloth is used to hold the dough into shape while in the final rise, just before baking. The couche is heavily dusted with flour which is rubbed into the pores of the fabric. Then the shaped dough is placed on the couche. The floured couche makes a "non stick" surface to hold the dough. Then ridges are formed in the couche to keep the dough from spreading. In the past, linen was also used for books (the only surviving example of which is the Liber Linteus). Due to its strength, in the Middle Ages linen was used for shields, gambesons, and bowstrings; in classical antiquity it was used to make a type of body armour, referred to as a linothorax. Additionally, linen was commonly used to make riggings, sail-cloths, nets, ropes, and canvases because the tensility of the cloth would increase by 20% when wet. Irish linen is very popular for wrapping pool and billiard cues, subject to absorption of sweat from hands—the linen maintains its strength when wet. In 1923, the city of Bielefeld in Germany issued banknotes printed on linen. United States currency paper is made from 25% linen and 75% cotton. ==Flax fiber==

Description stem cross-section, showing locations of underlying tissues. Ep = epidermis; C = cortex; BF = bast fibres; P = phloem; X = xylem; Pi = pith Linen is a bast fiber. Flax fibers vary in length from about 25 to 150 mm (1 to 6 in) and average 12–16 micrometers in diameter. There are two varieties: shorter tow fibers used for coarser fabrics and longer line fibers used for finer fabrics. Flax fibers can usually be identified by their "nodes" which add to the flexibility and texture of the fabric. The cross-section of the linen fiber is made up of irregular polygonal shapes which contribute to the coarse texture of the fabric. Properties Linen fabric feels cool to touch, a phenomenon which indicates its higher thermal conductivity (the same principle that makes metals feel "cold"). It is smooth, making the finished fabric lint-free, and gets softer the more it is washed. However, constant creasing in the same place in sharp folds will tend to break the linen threads. This wear can show up in collars, hems, and any area that is iron creased during laundering. Linen's poor elasticity means that it easily wrinkles. Mildew, perspiration, and bleach can damage the fabric, but because it is not made from animal fibers (keratin) it is impervious to clothes moths and carpet beetles. Linen is relatively easy to take care of, since it resists dirt and stains, has no lint or pilling tendency, and can be dry-cleaned, machine-washed, or steamed. It can withstand high temperatures, and has only moderate initial shrinkage. Measure The standard measure of bulk linen yarn is the "lea", which is the number of yards in a pound of linen divided by 300. For example, a yarn having a size of 1 lea will give 300 yards per pound. The fine yarns used in handkerchiefs, etc. might be 40 lea, and give 40x300 = 12,000 yards per pound. This is a specific length therefore an indirect measurement of the fineness of the linen (i.e. the number of length units per unit mass). The symbol is NeL. The metric unit, Nm, is more commonly used in continental Europe. This is the number of 1,000 m lengths per kilogram. In China, the English Cotton system unit, NeC, is common. This is the number of 840 yard lengths in a pound. Production method Linen is laborious to manufacture. of flax in Belgium. On the left side, cut flax is waiting to be baled. The quality of the finished linen product is often dependent upon growing conditions and harvesting techniques. To generate the longest possible fibers, flax is either hand-harvested by pulling up the entire plant or stalks are cut very close to the root. After harvesting, the plants are dried, and then the seeds are removed through a mechanized process called "rippling" (threshing) and winnowing. The fibers must then be loosened from the stalk. This is achieved through retting, a process which uses bacteria to decompose the pectin that binds the fibers together. Natural retting methods take place in tanks and pools, or directly in the fields. There are also chemical retting methods; these are faster, but are typically more harmful to the environment and to the fibers themselves. After retting, the stalks are ready for scutching, which takes place between August and December. Scutching removes the woody portion of the stalks by crushing them between two metal rollers, so that the parts of the stalk can be separated. The fibers are removed and the other parts such as linseed, shives, and tow are set aside for other uses. Next the fibers are heckled: the short fibers are separated with heckling combs by 'combing' them away, to leave behind only the long, soft flax fibers. After the fibers have been separated and processed, they are typically spun into yarns and woven or knit into linen textiles. These textiles can then be bleached, dyed, printed on, or finished with a number of treatments or coatings. ==See also==
