Highlighting the benefits of wool with Hettie

Hettie and the Campaign for Wool

Hettie are proud members of the Campaign for Wool and champion this wonderfully friendly fabric , using it for many of our product collections.

This week we join the campaign in highlighting the many benefits of wool for the future of our planet. And our children's future.

Against a background of misleading anti wool lobbying currently orchestrated by global giants of fast fashion, the Campaign for Wool decided to engage with leading academic experts in the field of land management and carbon sequestration to demonstrate the positive pastoral contribution the grazing of ruminants, particularly sheep, makes to the continued wellbeing of the planet.

These peer reviewed findings add to already well documented research revealing wool’s unique renewable and biodegradable end of life attributes and the contribution the fibre makes to the circular economy.


Ten reasons why wool matters

Pure wool is 100% natural, 100% renewable, 100% sustainable, 100% biodegradable, if you love the planet - use more wool

It is warm but it is cool too because it adapts to the wearer - that’s why sheep are so snug and content! 

Wool is flame retardant and will often self-extinguish. Fire-fighters like it because it produces less smoke and toxic fumes - making it a safer choice for the home. 

Strong and long lasting - wool carpets and rugs can take lots of heavy wear and are known to look better for longer - quality always lasts! 

Sleep well with a wool bed, pillow, duvet and blanket - scientific tests show that wool will create a sleep climate perfect for you... deeper sleep, lasting comfort and sweet dreams. 

Wool has hypoallergenic and anti-bacterial properties - it makes the air that we breathe cleaner and better. 

Wrap your babies in wool so they breathe easy... wool will keep them cosy and warm but not too hot as it cleverly changes to their temperature needs and is good for their skin. 

Insulate with it, soundproof with it, wear it, walk on it, wrap things with it. The world’s oldest renewable fibre is also the most versatile and modern. 

Sheep are amazing - they graze peacefully, grow wonderful wool, we use it to make beautiful textiles and the whole process begins again... no depletion, just sustainable and sensible. 

Wool is smarter than any other fibre - it travels a long way on its journey from the sheep to finished product but it never loses any of its remarkable qualities and it looks and feels fabulous too.


Why wool matters


Wool grows naturally on sheep, it is a keratin protein fibre, similar to human hair and is 100% natural and not man-made.


As long as there is grass to graze on, water to drink, air and sunshine sheep will produce a new fleece every year, making wool a renewable fibre source.


At the end of its useful life, wool can be returned to the soil or the marine environment where it decomposes, releasing valuable nitrogen-based nutrients into the ground/ocean.When wool is disposed of in soil or water, it takes a very short time to break down, whereas most synthetics and plastics are extremely slow to degrade, if at all.


Wool has a large capacity to absorb moisture vapour (up to 30 per cent of its own weight) next to the skin, making it extremely breathable, and comfortable to wear in extremes and changes of temperature.

Wool fibres are crimped, and when tightly packed together, in yarn or fabric, form millions of tiny pockets of air. This unique structure allows wool to absorb and release moisture vapour either into the atmosphere or via perspiration from the wearer - without compromising its thermal efficiency.


Whether it’s hot, cold, humid or dry, wool garments are one of the most breathable. Wool can absorb and release twice as much moisture vapour as cotton and thirty times as much as polyester.

When worn next to the skin, wool works as a dynamic buffer in the micro-climate between the fabric and the skin, regulating humidity and temperature.

Thanks to its hygroscopic abilities, wool constantly reacts to changes in body temperature, maintaining its wearer’s thermophysical comfort in both cold and warm weather.While the exterior layer of a wool fibre is hydrophobic (water-resistant), its inner layer, its cortex, is hydrophilic (water-loving). The cortex can absorb about to one-third of its weight in moisture without feeling damp.


Due to wool fibres being like a coiled spring they return to their original shape during wear and have a natural resistance to wrinkles. They resist tearing and are able to be bent back and forth on themselves over 20,000 times without breaking.


Since the Stone Age, wool has been appreciated as one of the most effective forms of all-weather protection known to man, and science is yet to produce a man-made fibre which matches its unique properties.

For thousands of years, sheep have been able to adapt to even the harshest of environments, as their wool protects them through hot , cold , dry and damp seasons.


Due to its crimped, zig-zag, structure, wool has a natural elasticity so wool garments have the ability to stretch comfortably with the wearer and then return to their natural shape, making them resistant to wrinkling and sagging. 

Wool maintains its appearance in the longer term, adding value to the product, reduces the requirement for excessive laundering and extending its lifespan.


The protective outer layer on a wool fibre makes wool products resistant to staining. Many wool products can now be machine-washed and tumble dried.

Recent innovations, in white goods and wool treatments, mean wool items are no longer hand-wash only. 


Merino wool is naturally anti-static which means it also attracts less dirt, dust and lint.


Wool is far more efficient than other textiles at absorbing sweat and releasing it into the air, before bacteria has a chance to develop and produce unpleasant body odour.

As wool absorbs the sweat moisture vapour it leaves less perspiration on the skin and is easily refreshed by airing. With wool's natural ability to shed dirt and bacteria it can be worn longer between washes


High in water and nitrogen content, wool is naturally flame-retardant. Wool does not melt, drip or to stick to the skin causing burns, and when subject to extreme heat it produces less smoke and less noxious 

fumes.Wool's requires high levels of oxygen in order to burn and has a far higher ignition threshold compared to other fibres which prevents the spread of flames. 


Wool provides good protection from the sun and has a naturally high level of UV protection, which is much higher than most synthetic fibres and cotton.

As a natural fibre, evolved over millions of years to protect sheep against the elements, wool absorbs UV radiation providing protection from the sun, making it a good choice for a wide range of outdoor activities.



Recently published research has demonstrated that wearing superfine wool next to the skin istherapeutic for eczema sufferers, challenging misconceptions that all wool is prickly and itchy.Medical professionals from across the world have reviewed research papers published during the past100 years to critically assess scientific studies claiming wool causes allergy. Debunking the ‘Myth of Wool

Allergy’ the researchers conclude that there is no credible evidence wool is an allergen. It found that if a fabric does cause sensations of itch and prickle on the skin then it is because of the large diameter/coarseness of the fibres and not due to the fibre type being wool.


It may surprise you to learn that wool could be the solution to a better night’s sleep. Wool is a naturalsleeping aid, so if you’re not sleeping well, switching to wool bedding is one way to improve your sleep quality.

The 7 Surprising Sleep Benefits of Wool - It keeps you cool, It keeps you warm, It stops you getting sweaty, Wool defeats dust mites, It defends against fungal spores, naturally safe and is naturally sustainable.


Sheep consume organic carbon by eating plants and store this in their fleece. Fifty percent of a fleece's weight is pure organic carbon stored in a durable, wearable form.
