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. | Bast fibers obtained from the stems of the fast-growing ''Hibiscus cannabinus'' plant.

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.
Synonyms and Related Terms
Hibiscus cannabus; mesta (India); meshta; Guinea hemp; Deccan hemp (India); Java jute (Indonesia); paco-paco (South America); ambary hemp; ambari hemp; awasthe hemp; bimli patam; bimli jute (India); gambo hemp; gombo hemp; Billipatam jute (India); sunee (India); brown Indian hemp (India); kenaf (Esp.); javajute; Jave jute; deccanhennep (levert juteachtige vezel) (Ned);
Physical and Chemical Properties
- Plant height = 1.5-3.5 m with woody base
- Stems=1-2 cm in diameter.
- Leaves=lobed (10-15 cm long)
- Fruit = capsule (2 cm) containing several seeds
- Fiber cross section = polygonal
Paper fiber type: non-woody/bast. Using transmitted light microscopy, fibers appear long, flat and thin. Faint dislocations, variable ends and lumens can also be seen. Vessels are profuse if whole plant is pulped. Appearance with Graff "C" stain: grey-blue. Average dimensions of fibers: length 5mm, width 21μm. Common pulping method: retting.
