Further, the quality jute fibre extraction from repeated retting in the same stagnant water was possible by using the highly efficient microbial formulation. The retting process consists of bundling jute stems together and, immersing them in slow running water. [C G Jarman] Home. Retting: the stem of jute is dried and stripped of unwanted leaves and is put in water and allowed to rot. The other consideration for early harvesting is to accommodate rice … Ret definition, to soak in water or expose to moisture, as flax or hemp, to facilitate the removal of the fiber from the woody tissue by partial rotting. Jute is an eco-friendly and bio-degradable natural product with no adverse effect on the environment. megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. the retting period particularly in West Bengal, jute growers were forced to ret their jute in muddy water leading to the inferior quality jute fibre and less net income. The traditional methods for separating the long bast fibres are by dew and water retting. Of these, 169 isolates have been purified and characterized. Search. Some machines combine breaking and scutching operations. [1], Natural water retting employs stagnant or slow-moving waters, such as ponds, bogs, and slow streams and rivers.

Harvesting, Retting and Extraction of Jute: Harvesting: Jute may be harvested at any time between 120 and 150 days after seeding. Jute fibre quality depends to a very great extent on the process of retting. It is obtained from the bark of plant through microbial retting process. If the fiber can easily be removed from the Jute hurd or core, then the crop is ready for harvesting. (2009). A total of 451 bacterial colonies have been isolate … The fibres are first extracted by retting. However, the quality of retting water is of great concern because of the scarcity of available water bodies for retting. Jute retting process is one of the important responsible factors for quality of jute fiber. Find answers and explanations to over 1.2 million textbook exercises. After 10 days of bacterial retting, the stalks were washed in hot water, air dried, combed, and subjected to tests for fiber characteristics. Final separation of the fibre is accomplished by a breaking process in which the brittle woody portion of the straw is broken, either by hand or by passing through rollers, followed by the scutching operation, which removes the broken woody pieces (shives) by beating or scraping. Not all bacteria isolated fromretted jute are responsible for theprocess, as for instance, seven species of aerobic bacteria were isolated fromretted jute but only oneof them, B. poly- myxa, was capable of retting jute … Faridpur, Comilla, Jessore, Dhaka, Kushtia, Jamalpur, Tangail, Pabna. Main content area. It is biodegradable, absorbs CO2 and releases O2 and N2 in the atmosphere. Waste material from the first scutching, consisting of shives and short fibres, is usually treated a second time. The bast fibres are stuck together with a ‘glue’ formed of pectins and lignins.

The bundles are steeped in water at least 60 cm to 100 cm depth. The retted stalks, called straw, are dried in open air or by mechanical means, and are frequently stored for a short period to allow "curing" to occur, facilitating fibre removal. Bundling jute stems together and immersing them in slow running water consists of the retting process. Retting operation was carried out for varying time period namely 10, 15, 20, 25, 30 and 35 days respectively. Early harvesting gives finer fibre of good quality and late harvesting gives larger yield of coarser fibre. To overcome problems of retting, the ICAR-Central Research Institute for Jute and Allied Fibres (CRIJAF), Barrackpore has developed an "in-situ retting tank based farming system model" to … However, during jute cultivation, jute plants are soaked in water for several days (a process called retting) in order to separate the fibres. i) Mechanical extraction of green ribbons through either power operated bast fibre extractor suitable for jute, mesta, sunnhemp and ramie or manually operated jute fibre extractor and.

Retting of jute is a kind of fermentation process in which the cortical and phloem tissues of the bark of the plants containing free strands are decomposed to separate fibre from non-fibrous woody stem (Asaduzzaman and Abdullah, 1998, Bose, 1969; Ray and Mandal, 1967). Water retting is a century old but the most popular process in extracting fine fibres. Retting Retting is a process in which the tied bundles of jute stalks are taken to the tank by which fibres get loosened and separated from the woody stalk.
