Kapok
PROPERTIES OF KAPOK
Kapok not only is a very ecological solution, it also delievers an astounding performance in several ways:
- light weight
The hollow core makes kapok very light, up to 8 times lighter than cotton by volume.
- excellent oil absorber
Excellent absorbing capacities for apolar fluids like fuel, machine oil or coconut oil - making Kapok a good choice for oil absorbent products as Kapok also contains the oil effectively.
- quickdry
Thank to its hydrophic nature, Kapok dries quickly.
- hypoallergenic
- warm
The cell structure allows it to trap air making kapok a good fibre to use for insulation.
- biodegradable
- buoyant
The waxy coating helps repel water, and air bubbles are usually trapped in lumen, making kapok 5 times more buoyant than cork. Kapok can support as much as 30 times its weight in water. In the past, kapok was used to fill life jackets.
- bounciness
Kapok resists clumping (i.e. it does not become lumpy) it also bounces back to the original shape after washing, a useful property when stuffing soft toys. It is traditionally used for stuffing teddy bears, giving them quite a different feel to modern polyester stuffing.
