Kenaf Hibiscus cannabis

Description

Bast fibers obtained from the stems of the fast-growing Hibiscus cannabinus plant. The plant is found throughout the world and the fibers have a wide variety of names: It is called paco-paco in South America; Java jute in Indonesia; and Billipatam jute, sunee, brown Indian hemp, Deccan hemp in India. Kenaf fibers were introduced to Europe in the late 18th century, but did not become widely used until the 20th century. Kenaf is a light colored fiber that is resistant to water. It is similar to jute and was used as a substitute during World War II. Kenaf is still used in burlap coffee bags and for ropes and cords. The woody core of the plant is used in paper products and particleboard. The oil from kenaf seeds is used for lamps.
