Jute
Description
Long bast fibers obtained from the stems of linden plants, Corchorus capsularis (white jute) or Corchorus olitorius (Tossa jute). Jute probably originated in the Mediterranean region and was taken to India and southeast Asia where it flourished. Jute has been used by man since prehistoric times. The pale brown fibers are soft, lustrous, and coarse ranging in length from 4 to 10 feet. Microscopically, the fibers exhibit irregular, long cells with a visible lumen. Jute is composed of Cellulose (69%), Lignin (18-20%) with some uronic anhydride (4.5%). The brittle fibers are used to produce a thread called hessian. Jute becomes so weak when wet that a thin twine can be broken by hand. It turns brown and degrades with time, sunlight, Water, acids, alkalis, and bleach. Jute is used to make sackcloth, burlap cloth, gunnysacks, Twine, Paper, and Carpet backing. It was also used to make brown paper in Europe in the mid-19th century.
See also Brazilian jute, Paco-paco, pita, and Curana.

Other Properties
Resistant to alkalis and dilute acids. Degraded by concentrated acids.
Fiber length = 1.5-3.0 m; Fiber width = 7-18 microns; cross section = polygonal with 5 or 6 sides. Moisture regain = 13.75%; Elongation = 1.7% (dry); Striations tend to be fine and often stop in the middle of the fiber; Fibers often are found in bundles.

Paper fiber type: Non-woody/bast. Using transmitted light microscopy, fibers appear short and narrow with thick walls. Dislocations are present but faint. The ends of fibers can be spoon-shaped with widened lumen. Appearance with Graff "C" stain: Orange-red, but greys with bleaching. Average dimensions of fibers: length, 2mm, width 20μm. Common pulping method: soda.
Hazards and Safety
Combustible. Poor resistance to sunlight, microorganisms and insects. Deteriorates rapidly when wet.
