Kapok/Capok fiber is one of the natural cellulosic fibers which grow on the kapok plant. It has a hollow body and a sealed tail, which are desirable features of candidates for functional textiles of this nature. However, the low volume weight of kapok is (specific density 0.29g/cm3), and the short length and smooth surface of the fibers, causing poor inter-fiber cohesion, have prevented kapok from being processed by modern spinning machines.

Kapok is silky fibers that clothe the seeds of the ceiba tree of the family Bombacaseae. Kapok fibers have rich oiliness and do not have high strength and, therefore cannot be spun economically. It is conventionally used as a stuffing, especially for life preservers, bedding, and upholstery, and for insulation against sound and heat.

The Kapok fiber has a hollow structure with an external radius around 8.25 (±4) _m, internal diameter around 7.25 (±4) _m, and length around 25 (±5) mm. Combined with the specific material density of 1.3 g/cm3 , the large pore volume in Kapok assembly is available for NAPL sorption. Typical analyses indicate that the Kapok fibers comprise 64% cellulose, 13% lignin and 23% pentosan. Besides these constituents, they also contain wax cutin on the fiber surface which makes them water repellent notwithstanding they are preponderantly composed of cellulose

•The Kapok tree is a deciduous tree that can be found in the forests of Asia and Middle America.

•It grows up to 70m and it has capsular fruits, which are picked and opened by hand.

•The fibers of the fruits are air-dried and not treated with chemicals.

•Kapok is a natural fiber that is completely biodegradable.

•The natural bitter constituents of the Kapok fiber are anti-bacterial and anti-microbial therefore

•Moths, mites and other microorganisms cannot infest the toy
