Wool - the ultimate eco-fibre
Wool is considered the premium eco-friendly carpet fibre for
very good reason. Wool carpets use 100% sustainable wool and
have a luxury and warmth that is not easily matched by synthetic
and corn/synthetic blend fibres.
Are you really buying 100% sustainable
carpet?
There are certainly some glamorous sounding 'eco-bling' fibres
in the market but a closer look at their fibre content shows that
most are around two-thirds synthetic to one-third corn starch - so
not a 100% sustainable or renewable fibre at
all, despite what their names may suggest. The
addition of corn content simply makes them less
synthetic. Be sure to ask your carpet retailer for
details on the fibre content of any carpet you are thinking about
buying. This should be visible on any sample labels or
marketing material. Wool vs synthetic and synthetic blend
carpets
For many people, the key reason to choose wool over synthetic is
for its eco-friendly and healthy properties. Cavalier Bremworth's
wool carpets, made right here in New Zealand, are 100%
sustainable and biodegradable unlike synthetic products which are
made from petrochemical products. And all Cavalier
Bremworth wool carpets carry Environmental Choice
accreditation, meaning we have met best practice environmental
standards in its production.
However we accept that both wool and synthetic has strengths and
weaknesses that need to be carefully considered when choosing your
carpet. Neither fibre is perfect and a good general rule to
follow is that you will get what you pay for in terms of quality
and performance.
The table below has been compiled from independent comparisons
of wool vs synthetic.
| Properties |
Wool |
Synthetic |
| Environmental friendliness - wool is a 100%
natural, renewable, eco-friendly resource that is
biodegradable. Synthetic carpets are derived from a
petrochemical source and the corn/synthetic fibre carpets have
majority synthetic content. |
√
|
|
| Ability to regulate humidity - ability to
absorb & release moisture - regulates atmospheric
humidity. Wool carpet can absorb up to 30% of its own weight
without feeling damp. Synthetics will start to fee damp
with only 2-3% moisture. |
√
|
|
| Resilience - The ability of the carpet to resist
or recover from crushing. A unique spiral crimp built into
wool fibre gives it natural bounce-back abilities. Some
better quality synthetic carpets with a mix of fibres will
reduce the likelihood of them flattening or matting. |
√
|
|
| Abrasion resistance - The ability of the carpet to
resist abrasion from very heavy traffic flows. |
|
√
|
| Insulation - the thicker the carpet the better the
insulation provided. Wool carpet can significantly reduce the
costs for heating and cooling - in some case by up to
12%. |
√
|
|
| Fire resistance - wool is naturally
flame-retardant, so it assists in meeting fire regulations.
Synthetic carpet has poor resistance to burning (it melts) and
gives off toxic and flammable gases. |
√
|
|
| Appearance retention - the ability of
the carpet to maintain its original good looks. This is
very much a case of you get what you pay for - better quality
carpets will last longer. |
√
|
√
|
| Stain removal - the ability to resist
& remove stains (good quality synthetics will have been treated
with stain blocking and anti-soiling chemicals). Prompt attention
to spills and stains and regular vacuuming can keep wool carpets
looking great for longer. No carpet fibre is completely
stain-resistant, despite the claims made on warranties - read the
fine print to see the key exclusions. |
√
|
√
|
| Resistance to soiling - The ability
of the carpet to resist general day to day, 'tracked in'
soiling. Wool's scaly structure means that dirt sits
more on the surface and can be vacuumed up easily. |
√
|
√
|
| Colourfastness - The ability to
resist fading by sunlight. No carpet, wool or synthetic,
is completely immune from sunlight fade. We recommend
the use of UV filters on windows where possible. |
|
√
|
| Contributes to air purity in buildings
- by absorbing & filtering VOC's (volatile organic
compounds). |
√
|
|
| Antistatic - Lifetime anti-static
guarantee (when anti static chemicals applied). |
|
√
|
| Comfort & ambience - softer feel,
natural bulk & resilience. |
