Jute? Here ya go ->
Jute is a long, soft, shiny
vegetable fibre that can be spun into coarse, strong threads. It is produced from plants in the genus
Corchorus, family
Malvaceae.
Jute is one of the cheapest
natural fibres, and is second only to cotton in amount produced and variety of uses. Jute fibres are composed primarily of the plant materials,
cellulose (major component of plant fibre) and
lignin (major components wood fibre). It is thus a ligno-cellulosic fibre that is partially a textile fibre and partially wood. It falls into the
bast fibre category (fibre collected from bast or skin of the plant) along with
Kenaf,
Industrial Hemp,
Flax (
Linen),
Ramie, etc. The industrial term for Jute fibre is
Raw Jute.

Jute plants (
Corchorus olitorius and
Corchorus capsularis)
Jute fibre is often called
hessian, jute fabrics are also called hessian cloth, and jute sacks are called gunny bags in some European countries. The fabric made from jute is popularly known as
burlap in
North America.
After the procurement of jute fibre through the
Retting Process, jute is graded (rated) according to its colour, strength, and fibre length. The fibres are off-white to brown, and 1-4 meters (3-12 feet) long. Jute is pressed into bales for shipment to manufacturers. From there, a typical processing sequence may include cutting, carding, drawing, spinning, reeling, plying, and twisting.
Here we go Mr. Wizard, into the organic chemistry of lignins and cellulose. You know, I actually thought it WAS hemp. Hemp is clearly different but related. Won't go there.
