Wool, an eco-friendly material

Laine_EcoResponsable_1

Tricolor is an original, collaborative and transversal project exploring the heart of the French wool sectors. The Tricolor project was initiated by Made in France Première Vision.

Wool is a noble and precious fibre.

Wool is warm, resistant, insulating and has many uses…

UIT Sud has fully investigated this fibre by compiling technical studies, and shares its natural technical characteristics and its many positive qualities in a particularly rich and educational tool: « Wool, a quality material. »

Discover these qualities in a series of 3 articles investigating wool’s performance features:

Today, a spotlight on its eco-responsible aspects!

Natural

Wool gets a green light! Of animal origin, fully renewable, recyclable, whose collection is vital for healthy sheep … every aspect of the lifecycle of wool makes it an eco-responsible resource. A perfect score!

It’s no secret that sheep re-constitute their coats yearly, making wool a 100% renewable natural resource whose collection is, moreover, important for the life of the animals. And to complete the circle, wool fibre is also 100% recyclable.

Respectful of landscapes

Blending in with a landscape is good – protecting it is even better. Wool goes all the way in this perspective, as it is produced through farm practices that contributes to the development of its environment. In fact, sheep farming plays an important role in maintaining French landscapes and the biodiversity of our countryside.

Sheep farming, together with its accompanying agricultural practices, is a key player in the care and maintenance of open and diversified landscapes. It contributes to soil quality by promoting the storage of carbon and enhances environmental balance by alternating hedges, groves, embankments, ponds and meadows rich in flowers, thus providing resources and habitats for a whole tribe of invertebrates, insects, birds and small wildlife (foxes, rabbits, etc.).

Biodegradable

Everything must go! With wool, waste is no problem – it’s biodegradable.

While synthetic materials can take 30 or 40 years to decompose, wool is biodegradable within just a few years.

A material is said to be biodegradable when it breaks down into simple molecules that can be used by plants through the action of living organisms such as bacteria and fungus. Such is the case with wool, which decomposes rapidly, particularly due to its high nitrogen content, and can therefore even be used to fertilize the soil.

Durable

Times change but wool remains. Wool products are strong and can be kept for a long time. A longer lifespan is a good way to fight waste and overconsumption.

Wool fibre has a macromolecular structure that is very resistant to twisting and bending (torsional stiffness: 200 10 N / m2) and a high elasticity in wet (50%) and dry (30%) conditions, allowing it to return to a state close to its original state in the event of deformity, and thus keep its shape much longer.

Dirt resistant and easy care

White is easily soiled … or maybe not. You may not know it, but even though wool is machine washable using the right programs, wool requires very little care. In fact, it’s almost wrinkle-free, attracts little dust and resists grease stains.

And limiting care means limiting the expenditure of water, electricity and chemical products… meaning limiting environmental impact.

Wool’s ability to avoid creasing, and smooth out easily is explained by the high degree of elasticity in wool fibre (30% and 50% in a wet environment). Its ability to retain water (15- 35%) allows it to produce less static electricity than other fibres, and therefore attract and retain less dust. Its oil-resistant nature also makes it less vulnerable to greasy soiling.
