Flax is the plant, while “linen” is the textile made from its fibre. The word flax is used for the plant and raw fibre, whereas linen refers to the yarn, fabric, and finished products produced from flax fibre. Linen is the world’s oldest documented fiber, and some evidence dates as far back as 6,000 BC. It is a natural cellulose fiber that comes from the flax plant and gains the name Linen once the fibers have been through the proper industrial preparation process. It is one of the strongest natural fibers, and it is considered luxurious – requiring care during each stage of careful textile production, which is a costly process. Consequently, linen is quite commercially expensive.
Flax can be grown for either the fiber for textile manufacturing use or for the seed to produce linseed oil, which is used in paints, varnishes, wood protection applications etc. Flax for textiles is grown in a wide range of countries, including Austria, France, Poland, Germany and Denmark, but the highest quality flax comes from Belgium, Ireland and Italy.
Linen is a natural bast fiber, it comes from a plant stem, with a staple length that varies from 25 cm to 150 cm; the shorter fibers are used for coarse, heavyweight fabrics, which are generally inexpensive, and the longer fibers are used for fine linens and sheer fabrics. The fabrics are very distinctive as they have a visible natural slub texture in the weave.
The fabrics are seldom 100% linen in knitted garments because the fibers have a natural stiffness and resistance to form the required loops of the knit structure, but they may be blended with other fibers to produce knitted fabrics with specific performance properties.

Properties of Linen Fiber
Absorbency: Linen has a much higher absorbency rate than cotton, and it dries quickly, hence its traditional household use for tea towels and handkerchiefs. It can absorb 20% moisture without feeling wet, and its strength increases by 20% in wet processing conditions. It has a much better wicking ability than cotton, which makes it more comfortable to wear in warm humid conditions. Linen absorbs dyes, but the colors have a slight tendency to fade in the wash.
Strength: Linen is very strong – almost three times as strong as cotton and almost as strong as natural silk.
Conductivity: Linen conducts heat efficiently and is therefore suitable for hot climatic conditions.
Flammability: Linen is a cellulose fiber, which means it is highly flammable and smelling of burning paper.
Shrink-Resistant: There is little shrinkage in linen due to the extensive processing the fibers undergo during production.
Resistance: Linen is resistant to insect attacks and alkalis under normal conditions. However, alkali perspiration may cause discoloration. Linen has a natural inherent ability to be antifungal, antibacterial, dust-resistant and stain-resistant so is often used in the medical textile industry for its natural healing properties. Fabrics made from linen will resist high temperatures so white linen can be laundered as high as 90°C although it will scorch if excessive ironing heat is applied for too long in one place.
Susceptible: Linen has no elasticity and little resilience, which causes it to crease easily during regular wear. If a linen fabric has creases pressed into it, the stiff, brittle fiber can crack over extended use. Due to the stiffness of the fiber, linen has poor draping qualities (though it drapes better than cotton). Linen can be damaged by a variety of acids, including acidic perspiration and bleach during improper care. Like cotton, linen is susceptible to mildew if it is kept in damp storage conditions. Although linen is highly absorbent, it does not have a strong affinity for dyes. Vat-dyed linen has a greater chance of retaining its color through repeated wash cycles. Linen should be ironed while damp or with a steam iron.
Sustainability: Linen is a renewable, sustainable resource derived from natural agriculture. It is biodegradable and can be recycled easily. During the retting process flax was traditionally a dew and water process which was costly but now manufacturers use an enzyme-based method which causes the woody structure to break down quicker and inhibits excessive bacterial and fungal growths which occurred with the traditional retting process.
Production Process of Linen Fiber
Flax plants are produced in Australia, Austria, Belgium (which produces the finest quality flax), Czech Republic, France, Germany, Ireland (which is known for its textile workmanship), and the Netherlands.
Cultivation
Seeds are sown in April or May on well-cultivated land that has been enriched for several years. Weeding is essential in order to avoid stunted growth during early development. The flowers are blue (the finest fiber), white or purple (coarse but mechanically stronger fiber).
Harvesting
At the end of August, the brownish color of the plant indicates that it is ready to be harvested at optimal maturity. Harvesting early is important to prevent the fiber from losing its natural surface luster. The stalk must be kept intact to prevent sap loss, which will affect the final quality of the fiber. Bundles of flax, called beets, are tied and prepared for safe transportation.
Rippling
The leaves and seeds are removed when they are passed through coarse combs during mechanical separation. The by-product of the seeds is linseed for industrial use.
Retting
The stems are retted, which allows for the removal of the phloem and xylem (fibers) through controlled decomposition. There are numerous ways to steep the stems:
Dew: The stems are spread out on a field for three to four weeks under natural conditions.
Pool/Dam: The stems are put into stagnant pools of water and left for ten to fifteen days under controlled soaking. This method darkens the fibers and turns them bluish-grey in final appearance.
Vat/Mechanical: The stems are submerged in wooden vats of warm water for a few hours to speed up the retting process. The stems are then passed between rollers to crush the bark as clean water flushes away the pectin and other impurities that are present. This process can cause mildew to form under poor control.
Chemical: Soda ash, oxalic soda, and caustic soda in warm water is used to shorten the overall process. Chemicals can affect the strength and color of the fiber if improperly applied.
Breaking
Once the stalks have become partially separated from the fibers in the retting process, the stalks are crushed between iron rollers, which also remove the liquid during mechanical action. The broken stalks are called shives in textile terminology.
Scutching
A machine removes the shives, leaving the fibers behind in a clean form.
Hackling or Combing
The fibers are combed to straighten them and separate the short fibers from the long ones for further processing.
Short-fiber Route
Short Fibers: These fibers are made into a tow that will be carded (combed again) to produce a sliver for coarse yarn production.
Dry Spinning: This is carried out to produce an irregular, rough yarn that is not very strong for low-cost applications.
Usage: Coarse, heavy fabrics are inexpensive and used to create cheaper items for general utility purposes.
Long-fiber Route
Long Fibers: These fibers are put into machines called spreaders. They separate the fibers and make them parallel at the same time for uniform alignment. The fibers have a slight twist to hold them together and maintain fiber cohesion. They are called slivers. These slivers are spun to produce a smoother, stronger yarn, which is used for high-quality fine linens.
Wet Spinning: The slivers pass through water at 50°C to remove any gum and are pulled into thinner strands called rovings during controlled spinning. These rovings are drawn and spun into a fine yarn for premium fabrics.
Usage: Sheer fabrics and fine linens (often called line or dressed flax) are created from these fibers for luxury textiles.
Finishes of Linen
Scouring to prepare the fabric for dyeing and other wet finishes.
Bleaching can be done with natural sunlight, which is very time consuming but less harmful to the fabric fibers. Chemical bleaching is achieved by boiling the material in a lime solution, rinsing it in water, bleaching it again with hydrochloric acid, rinsing it once more, and finally treating it with caustic soda through chemical treatment. There are various grades for bleached linen that range from full to ¾ to ½ to ¼ to unbleached. The strength of the fabric is affected by these processes; fully bleached is the weakest and unbleached is the strongest in fabric integrity.
A crease resistant finish is costly and only carried out on very luxurious fabrics for high-end products.
Calendering for added luster and surface smoothness through mechanical pressure.
Sizing to add body and stiffness to the fabric for better handling.
Beetling for flexibility and creating uniform thickness across the fabric for enhanced quality.
Types of Linen Fabrics
Linen fabrics are categorized based on weave structure, yarn fineness and intended end use. Each type of linen fabric offers distinct performance characteristics, surface appearance, and durability, making linen suitable for a wide range of textile applications.
Most Common: Batiste, cambric, damask, glass towelling, lawn and sheeting. These types of linen fabrics are widely used in apparel and household textiles due to their breathability, strength, and comfort. They range from lightweight, smooth fabrics suitable for garments to heavier constructions used for bed linen, table linen, and kitchen textiles.
Less Known: Barras, Holland, Venisse and butchers’ linen used in specialized textiles. These fabrics are produced in smaller quantities and are typically used for industrial, professional, and home furnishing purposes where higher durability, firmness, or decorative structure is required.
The variation in linen fabric types reflects differences in yarn quality, spinning method, weaving technique, and finishing processes, allowing linen to meet both everyday and high-performance textile needs.
Uses of Linen
Linen is valued across the textile industry for its strength, breathability, absorbency, and natural comfort. Because of these properties, linen is used in a wide range of apparel, household, industrial, and medical textile applications.
Tablecloths, suits, skirts, trousers, dresses, tops, blouses, shirts, upholstery, curtains, canvasses (for artwork), handkerchiefs, tea towels and traditional bed linen. It also has some medical uses in healthcare textiles.
In apparel, linen is especially popular for warm-weather clothing due to its excellent moisture absorption and cooling effect. In household textiles, linen is widely used for table and bed linens because of its durability and resistance to high washing temperatures. Linen canvasses are preferred by artists for their strength and long-term stability, while upholstery and curtains benefit from linen’s natural texture and aesthetic appeal.
In medical textiles, linen is used for bandages, surgical garments, and hospital linens because of its antibacterial properties, breathability, and ability to withstand frequent laundering at high temperatures.
