Wool & Microclimates
When used in bedding, wool creates a micro climate which
assists in regulating body temperature and humidity, providing
a more rested night's sleep.
(A) Thermal Comfort
Wool provides a high level of thermal comfort due to its outstanding
insulating properties. Wool offers warmth under cool conditions
because the natural crimp of the fibre allows air to be trapped.
The thermal resistance of air means it is six to ten times
as insulating as any fibre.
This insulating property of wool ensures that temperature
changes are slow and gradual when wool is used in a bedding
situation, avoiding rapid temperature changes.
(B) Moisture Absorption
Wool can absorb up to 30% of its own weight in water without
feeling wet (hydrophilic). The reason for this is that its
constituent keratin is very rich in amino acids which easily
bind together with water molecules. Wool is particularly hydrophilic
when water is present in the form of vapour.
As humidity levels rise, wool fibres absorb and store the
moisture, keeping the humidity at skin surface relatively
low. The absorbed moisture in the wool fibre can also be diffused
into the atmosphere.
This property ensures that damp, clammy feeling will never
be experienced with wool.
