Kapok fibre

It has a hollow tube structure consisting of about 35% cellulose and nanocellulose, 22% xylan and 21.5% lignin in the dry fibre.

[3] A kapok fibre is a thin-walled hollow tube with a diameter of about 15 to 35 μm (0.59 to 1.38 mils) and wall thickness about 1 to 2 μm (0.039 to 0.079 mils), filled with up to 80% air by volume, giving it a density of about 1⁄8 that of cotton fibre.

[4] Kapok is grown and exported from Nigeria, Mozambique, and Tanzania in Africa, Sri Lanka, Indonesia, Thailand, and the Philippines in Asia, and Ecuador in South America.

[1] The product is transported in bales of about 100 kg (220 lb), but at low compression to prevent excessive compaction.

Kapok fibers can be used as fill for pillows, quilts and other bedding, upholstery, and soft toys.
