Kapok tree

Description

Short, lightweight cellulosic fibers obtained from the seeds of the silk cotton tree, Ceiba pentandra, primarily grown in Java, Africa, Brazil, India, and Central America. Kapok is composed of 43% Alpha cellulose, 24% pentose, 15% Lignin, and 6.6% uronic anhydride. The soft fibers have a smooth surface and are transparent. Kapok is buoyant and will support up to 30 times its own weight. The fluffy fibers are too brittle to spin and are used for filling mattresses, upholstery, and life jackets.
