Wool has many appealing properties; it is durable, able to filter air-borne properties, odour resistant, and is naturally flame retardant. Thanks to this, not only is it a popular material in the clothing and fashion industry, but it has also become an increasingly popular insulating material for homes and is widely used in commercial buildings. The ability of wool to improve indoor air quality makes it a useful textile in the homes of allergy sufferers. Wool also meets many international flammability regulations without any need for further treatment which makes it a very convenient material for carpets in commercial buildings. If it does ignite, it will not melt, drip or spread noxious fumes, unlike many man-made fibres.
Wool can be considered a “weatherproofed” material thanks to its exposure to the elements during its time on the sheep. This gives it unique qualities when compared to other textiles, and means it can last much longer than many alternatives. Despite this durability, wool is also naturally biodegradable in both soil and marine environments. This releases valuable nutrients back into the environment, with the additional benefit that 100% wool products will not contribute to any plastic or micro-fibre pollution. Thanks to this, there has been an increase in the popularity of wool coffins!
