Environmental Data

Quantity Value Unit
Environmental remarks Jute fiber production takes mainly place in India, Bangladesh, China and Thailand. The jute plant can be harvested after four months growing. On average the jute plant is composed of 12,5% leaves, 48% wood and 39,5 % ribbon. Jute fibers are gained from the ribbon by retting the the bast in water for about 5 to 22 days. Some pesticides and fertilisers are applied. on the jute fields, but jute cultivation causes no soil erosion, because of the short growing period and crop rotation with rice and potatoes. During the retting process the water is polluted with organic substances, which causes depletion.

General

     
Remarks Bast fiber. One of the cheapest natural fibres. Poor resistance against moisture, brittles under influence of light, absorbs paint easily. Jute consists of very short elementary fibers (lenth 0,7-6 mm) wich are stuck together by lignin to form long brittle fibers (length of 300-400 mm).
