Linen

Linen is a Textile material made up from the fibres of the flax plant. Linen is laborious to manufacture, but the fiber is very absorbent and garments made of linen are valued for their exceptional coolness and freshness in hot weather.

Products are made of linen
👉 Aprons,
👉 Bags,
👉 Towels
👉 Napkins,
👉 Bed linens,
👉Tablecloths, 
👉 Men's and women's wear.

History

The word linen is of West Germanic origin and cognate to the Latin name for the flax plant,linum, 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. Textiles in a linene weaves texture, even when made of cotton hemp and other non-flax fibers, are also loosely referred to as "linen".

👉 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 linen. In the past, "linens" also referred to lightweight undergarments such as shirts,waist-shirts, lingeria(a word also 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 jackets) was traditionally made of linen, hence the word lining.

Description

Linen is a bast fibres. Flax fibers vary in length from about 25 to 150 mm (1 to 6 in) and average 12-16 micrometer 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.

Structure

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 the touch. 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 has poor elasticity and does not spring back readily, explaining why it wrinkles so easily.

👉Linen fabrics have a high natural luster; their natural color ranges between shades of ivory,ecru, tan, or grey. Pure white linen is created by heavy bleaching. Linen fabric typically varies somewhat in thickness and is crisp and textured, but it can in some cases feel stiff and rough, and in other cases feel soft and smooth. When properly prepared, linen fabric has the ability to absorb and lose water rapidly. Linen can absorb a fair amount of moisture without feeling unpleasantly damp to the skin, unlike cotton.

👉 Linen is a very durable, strong fabric, and one of the few that are stronger wet than dry. The fibers do not stretch, and are resistant to damage from abrasion. However, because linen fibers have a very low elasticity, the fabric eventually breaks if it is folded and ironed at the same place repeatedly over time.Linen should not be dried too much by tumble drying, and it is much easier to iron when damp. Linen wrinkles very easily, and thus some more formal garments require ironing often, in order to maintain perfect smoothness. Nevertheless, the tendency to wrinkle is often considered part of linen's particular "charm", and many modern linen garments are designed to be air-dried on a good clothes hanger and worn without the necessity of ironing.

👉A characteristic often associated with linen yarn is the presence of "slubs", or small knots which occur randomly along its length. In the past, slubs were traditionally considered to be defects, and were associated with low quality linen. However, in the case of many present-day linen fabrics, particularly in the decorative furnishing industry, slubs are considered as part of the aesthetic appeal of an expensive natural product. In addition, slubs do not compromise the integrity of the fabric, and therefore they are not viewed as a defect. However, the very finest linen has very consistent diameter threads, with no slubs at all.

Measurement of Linen

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.

Producers

Flax is grown in many parts of the world, but top quality flax is primarily grown in Western European countries and Ukraine. In very recent years bulk linen production has moved to Eastern Europe and China, but high quality fabrics are still confined to niche producers in Ireland, Italy and Belgium, and also in countries including Poland, Austria, France, Germany, Sweden, Denmark, Lithuania, Latvia, the Netherlands, Spain, Switzerland, Britain and kochin in India. High quality linen fabrics are now produced in the United States for the upholstery market.

Uses

Over the past 30 years the end use for linen has changed dramatically. Approximately 70% of linen production in the 1990s was for apparel textiles, whereas in the 1970s only about 5% was used for fashion fabrics.

👉 Linen uses range from bed and bath fabrics (tablecloths, dish towels, bed sheets, etc.), home and commercial furnishing items (wallpaper/wall coverings, upholstery, window treatments, etc.), apparel items (suits, dresses, skirts, shirts, etc.), to industrial products (luggage, canvases, sewing thread, etc.). It was once the preferred yarn for handsewing the uppers of moccasin-style shoes but its use has been replaced by synthetics.

👉 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 with 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.
