Wool is a sustainable and renewable natural fibre that has been grown by sheep for thousands of years and processed into textiles before Roman times. Each year a sheep grows a fleece of wool which is harvested by a practice called shearing. From here the raw wool is scoured (washed) and made available to processors to be combed, carded, spun, woven or felted into a large range of yarns or textiles. Wools many unique characteristics include:

Crimp: The natural crimp of each individual wool fibre enables ease of spinning, greater bulk and heat insulation that many synthetic fibres can not achieve.
Elasticity: Enables wool fibres to be stretched and crushed yet allow wool garments and products to return to their natural shape after stress and hard wearing.
Hygroscopic: Wool can readily absorb moisture without actually appearing or feeling wet.
Fire Resistance: Wool is harder to ignite than cotton and nearly all synthetic fibres making it a great choice in sleepwear, childrens clothes, bedding and industrial applications.
Static Resistance: Wools ability to retain some moisture helps prevent a build up of static electricity.
Allergy Prevention: Wool fibres produce yarns and products that allow air to circulate and breath and therefore can provide health benefits for allergy sufferers.

These and other characteristics enable wool to be processed into many forms, used in many different products and marketed as a sustainable and environmentally friendly textile fibre.
