FAQ on linen: we tell you everything!


Linen, an amazing natural fiber, ultra resistant. Indeed, more and more start-ups are interested in this fiber to manufacture all kinds of products. For example, skis, snowshoes or even boat hulls...

A little history

Flax is considered as the oldest textile in the world. Indeed, its age is estimated at more than 36 000 years. Everything leads us to believe that the men of this time worked this fiber to replace their clothes made of animal skins. However, we can imagine that their linen clothes were much less comfortable than today... Indeed, the processing of the flax plant into fiber is a complex operation.


The fabric is thermoregulatory. That is to say that it brings heat when it is cold. And conversely, it will bring freshness when it is hot.

Cultivation of flax

The culture requires a certain know-how and a very specific climate which make this plant a French heritage to be preserved.
First of all, the seeds are planted in mid-March, early April. The flax then takes 100 days to flower. It can then reach up to 1.2 meters in height. Finally, the flax delivers a blue flower whose life span does not exceed a few hours.
In July, the plant is firstly pulled up and not cut to preserve all the fibers that compose it. Secondly, it is deposited in a windrow on the ground to give way to the magic of retting. Thirdly, from July to September, the retting takes place, a key stage in the cultivation of flax. It is at the same time an alternation of rain and sun but also the action of certain micro-organisms present in the ground. These 2 natural phenomena make the flax turn red and give it its particular color and its specific characteristics.
In order to obtain a homogeneous retting, the swaths are turned over and then rolled up in bundles.


Powerful anti-allergic

In contrast to other fabrics, linen fibers retain almost no allergenic elements. In fact, the texture acts to prevent bacteria from attaching to it and provides a very effective antibacterial action. Flax is a proven bacteria repellent and that is why it is used so much in everyday life and is perfect for anyone suffering from allergies or eczema.


The linen chain, from the bale to the article made by Thieffry frères

First of all, the bales of linen are received by dyers. Then, they will undergo a succession of mechanical processes to separate its various components, including the famous flax fiber.
The fibers are then sent to a spinning mill whose role is to assemble the fibers together to form a thread.
The spools of yarn are then sent to a weaving mill. Here, the threads will be crossed to each other, the warp and the weft, to form a fabric, with or without pattern.
The rolls are then cut according to the pattern of the different articles and sewn by our seamstresses.
Tadaaaaam! Your item is ready to be sent to you!!!"

Noble and soft

Smell its scent and caress the linen, you will be won over!

Linen, an exceptional ecological product!

The culture of linen is naturally excellent for the environment. Indeed, its organic culture requires practically no fertilizer, nor pesticide thus preserving our grounds. Moreover, another advantage is that the fields do not need to be irrigated since rainfall often provides enough water for the plant.

The retting process is once again 100% natural, using the sun, the rain and the earth.
Finally, all the steps to go from the flax bale to the final product are mechanical events. As a result, water resources are saved. And besides, chemicals are forgotten...


Flax is an endemic plant of Normandy and the North. A great asset for our agriculture and the industry.

On the other hand, a paradox due to globalism, 80% of French linen is sent to Asia for treatment and manufacture. Choose well!

France, world champion!

France is the world's leading producer of linen. Indeed, the plant requires very specific growing conditions: a deep soil, a temperate and humid climate marked by alternating rain and sun. Thus, 80% of the world's flax production comes from the northern regions of France.
