Linen Creases Because of Exactly What Makes It Good, and Most of the World's Crop Grows in One Corner of France

Linen is the fabric people reach for when the temperature passes forty, and it is also the fabric people complain about most. It creases the moment you sit down. It costs more than cotton for what looks like a coarser cloth. Half the linen on the high street turns out to be a blend. All three complaints have the same answer, which is that linen is an unusual fibre made by an unusual process, and once you understand the process the buying decisions make themselves.

A fibre from a stem, not a boll

Cotton is a seed hair. Linen is a bast fibre: it comes from the stem of the flax plant, Linum usitatissimum, where long bundles of cellulose run the length of the stalk just under the skin and hold the plant upright. Getting them out is the whole difficulty of linen, and it has not fundamentally changed in five thousand years.

The plant is pulled rather than cut, roots and all, to keep the fibres at full length. It is then left lying in the field for several weeks in a process called retting, in which dew, rain and soil microbes rot away the pectin that glues the fibre bundles to the woody core. Ret too little and the fibre will not separate. Ret too long and it weakens. Judging it is the skill of the grower, and it is why the same field can produce a different quality of linen in a wet year and a dry one.

After retting the dried stalks are scutched, which breaks and beats away the woody core, and hackled, which combs the fibres parallel and separates the long line fibres from the short tow. The long fibres are spun into the yarn for shirting and tailoring. The tow goes into coarser cloth, rope and paper.

All of this is slow, most of it is mechanised only partially, and it explains the price. It also explains where linen comes from. FAOSTAT figures for 2022 put world production of raw flax fibre at a little under 876,000 tonnes, of which France grew almost 653,000, roughly three quarters, with Belgium a distant second. The strip of coastal Europe between Normandy and the Netherlands has the mild, damp climate that dew retting needs, and the European industry certifies its fibre through the Alliance for European Flax-Linen and Hemp. A garment carrying that certification was made from European-grown fibre, although it may have been spun and woven anywhere.

Why it behaves the way it does

Flax fibre is cellulose in a highly ordered, crystalline arrangement, which gives it two properties that matter to the wearer.

The first is strength. Linen is stronger than cotton, and unusually it is stronger wet than dry, which is why linen sheets survive a century of laundering and why a linen shirt outlives the cotton one bought the same summer.

The second is stiffness. The fibre has very little elasticity. Bend it and it does not spring back; it takes a set, and that set is a crease. There is no finishing process that removes this without damaging the fibre, and a linen garment that does not crease is either a blend or has been resin-treated. The creasing is the fibre being what it is. Buy linen on the understanding that it will look lived in by lunchtime, or buy something else.
