Jute

Jute “Golden Fiber” of Calcutta. These can be woven together to make bags, floor mats, wall, the list never ends…. Jute was once the economic engine of the country. Its share of the world export market peaked in the Second World War and the late 1940s at 80% and even in the early 1970s accounted for 70% of its export earnings. However, polypropylene products began to substitute for jute products worldwide and the jute industry started to decline. In recent years jute has come back into favor because it is a tough fiber, widely available, and bio-degradable.
My good friend Wikipedia contributes the following:
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, which has been classified in the family Tiliaceae, or more recently in Malvaceae.
Jute is one of the most affordable natural fibres and is second only to cotton in amount produced and variety of uses of vegetable fibers. Jute fibres are composed primarily of the plant materials cellulose (major component of plant fibre) and lignin (major components of 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. The fibres are off-white to brown, and 1–4 metres (3–12 feet) long.
Jute fibre is often called hessian; jute fabrics are also called hessian cloth and jute sacks are called gunny bags in some European countries.
