- Abstract
Kapok (Ceiba pentandra) is a highly lignified organic seed fibre, containing 22-45% of cellulose, 22-45% of hemicelluloses, and 15-22% of lignin. In its primary cell wall kapok contains, in addition to waxes, a high percentage of inorganic substances, which, in combination with a high percentage of acetyl groups, imparts excellent hydrophobic properties to kapok even after removal of waxes. Low fibre density, i.e. 0,348 gcm-3, is attributed to a wide lumen, which occupies approximately 74% of a kapok fibre. Due to such wide lumen, kapok has an exceptional capability of liquids retention. Kapok boasts with good anti-microbial properties. It is distinguished from other cellulosic fibres by its excellent thermal and acoustic insulating properties, high buoyancy, and good oil and other non-polar liquids absorbency. Kapok is mainly used in the form of stuffing and nonwovens; it is rarely used in yarns, mostly due to low cohesivity of its fibres and their resilience, brittleness, and low strength. New potentials of kapok have been opening in the field of technical textiles, yachts and boats furnishing, insulating materials in refrigeration systems, acoustic insulation, industrial wastewaters filtration, removal of spilled oil from water surfaces, and reinforcement components in polymer composites. Kapok is physiologically inert. It is also used in nutrition for selective elimination of fats.
