Kapok Fiber










Kapok is the most used common name for the tree and may also refer to the cotton-like fluff obtained from its seed pods. The tree is cultivated for the seed fibre, particularly in south-east Asia, and is also known as the Java cotton, Java kapok, silk-cotton or  ceiba.

The word kapok refers both to the tree and to the fibre it produces, which is also known as silk cotton or Java cotton. The hair-like fibres that surround the kapok seeds are best used as a stuffing, where they have several advantages over more commonly used materials. Kapok fibres on their own are not suitable for spinning into yarn, as they are too smooth, slippery and brittle. Kapok is similar to cotton in that both fibres are found around the plant seeds, rather than extracted from the stem or leaves.

Kapok fibres are lustrous, yellowish brown and made of a mix of lignin and cellulose. Each fibre is about 2.5 cm long, has a wide lumen (central cavity) and thin walls covered with waterproof wax.



  • Light weight: the hollow core makes kapok very light, 8 times lighter than cotton by volume.
  • 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.
  • Packs down firmly: this characteristic makes kapok useful to stuff meditation cushions.
  • Slippery: the waxy coating also makes kapok slippery, it therefore easily adjusts to shape, for example of the head on a pillow.
  • Hypoallergenic
  • Warm: the cell structure allows it to trap air making kapok a good fibre to use for insulation.



  • It is irritant: as the fibres are designed to disperse seeds on the wind, it is advisable to wear a dust mask when stuffing items with kapok, as the fibres fly in all directions and can irritate the lungs.
  • It is inflammable: the trapped air makes kapok highly inflammable, and if it catches fire it is difficult to put the fire out. Special precautions are needed to transport kapok in the hull of ships. One advantage of this characteristic is that kapok can be used as tinder.

Environmentally friendly: unlike polyester stuffing, kapok is a natural biodegradable fibre. It can be reused many times without developing mould or decaying.



Kapok finds use in bedding and upholstery industries, in the production of life-saving equipment, and in the construction of thermally insulated and soundproof covers and walls. On account of its buoyancy, freedom from water-logging and weight-bearing capacity, it is the material par excellence for the manufacture of lifebuoys and belts, waistcoats and other naval life-saving appliances. The buoyancy of kapok is about five times as great as that of cork and about three times that of reindeer hair. During the war, kapok was employed for insulating tanks, for lining aviation suits, for filling floats of army assault-bridges, and generally for replacing cork wherever lightness, moisture-resistance and floating power were needed.

The kapok fiber once used in floatation vests and has been used as building insulation has a hollow fiber and looks like glass fiber under the microscope. The hollow fiber has air inside allowing combustion deep inside the material. Smoldering fire and open flame travel quickly within the material.

  • Kapok was considered unsuitable for textile purposes, because the fibre is brittle, smooth and slippery.
  • Refined kapok seed oil is used for the same purposes as refined cottonseed oil. The wood is light and soft and is suitable for making canoes and toys. It is used for matches. The root bark yields a fibre.

The market for kapok fiber or kapok fibre used as stuffing has declined considerably over the last 30 years, as it is replaced by polyester stuffing and foam plastics. There is, however, renewed interest in kapok fiber especially for textile applications or textile industries.
