Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks.

Retting, process employing the action of bacteria and moisture on plants to dissolve or rot away much of the cellular tissues and gummy substances surrounding bast-fibre bundles, thus facilitating separation of the fibre from the stem. Basic methods include dew retting and water retting. Dew. Note: Citations are based on reference standards.

Jute cultivation in red soils may require high dose of manure and pH range between is best for its cultivation.

Plain land or gentle slope or low land is ideal for jute cultivation. Since the jute seeds are small in size, land should be prepared to fine tilling, which can be done by careful ploughing. Retting. Introduction. 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,Bose, ; Ray and Mandal, ).The fermentative microorganisms consume the cementing materials viz., the pectins, hemicelluloses and proteins Cited by: RETTING PROCESS OF SOME BAST PLANT FIBRES AND ITS Retting is the main challenge faced during the processing of bast plants for the production of long fibre.

The traditional methods for separating the long bast fibres are by dew and water retting. Both methods require 14 jute, flax, and kenaf, with an emphasis on kenaf. Amongst the bast.

Here the most common practice of retting is to immerse the jute bundles in lakes, rivers, canals, tanks,ponds or ditches in layers for about days to be extracted manually. Retting If hemp or flax (linen) fibers are to be used in textiles and other high-quality applications, the bast fibers must be separated from the rest of the stalk.

Retting is a microbial process that breaks the chemical bonds that hold the stem together and allows separation. The Complete Book On Jute & Coir Products (with Cultivation & Processing) by Npcs Board Of Consultants & Engineers, ISBN:Rs.

/ US$. 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. The. Jute (Corchorus olitorius) retting process after harvest of the crop has a vital role in producing quality jute fibre and consequently fetching high prices to the farmers.

The book discusses the overview of the Jute & Coir along with their Classification, Structure, Properties and Manufacturing Process of different products. Few major contents of the Book are Jute Cultivation, Coconut Cultivation, Jute Yarn, Sutli retting of jute book Hessian Cloth.

Many water bodies like rivers, canals and ponds are becoming polluted due to retting of jute plants in these water bodies as ribbon retting, a method for retting the plants with less water, is yet.

Sep 03,  · An ongoing dry spell has turned waterbodies in Jhenidah almost empty, leaving farmers without much option for retting jute. Finding no other alternative, many of Author: Azibor Rahman. Sep 01,  · Retting Environment • Jute assimilates about ton CO2 from the atmosphere in its lifetime (Rahman and Bala, ).

• Conventional retting practice emits a little bit more nutrients, biogas and residues to the air and water compared to ribbon retting. • Total methane generation from jute production is estimated to be x g/year.

• J Pectin and lignin bonds inherited in Raw Jute can rot or deteorate the quality of the Jute Fibre. However, this weakness can be overcome by proper retting, washing, drying process and modification of jute fibre.

Use of Jute Plant for Making Composites as Wood Substitute[4]. The effects of citrate phosphate buffer and EDTA singly on jute ribbons were also studied under identical conditions.

RESULTS AND DISCUSSION Efficacy of commercial enzymes in retting jute ribbons Table 1 depicts the polysaccharide degrading capabilities of the commercial enzyme preparations used in retting experiments with jute by: Jute retting process: present practice and problems in Bangladesh Abstract: Jute retting process is one of the important responsible factors for quality of jute fiber.

Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. The main purpose of this study was provided information about the Jute retting. Retting Practies: In general, the practice of retting jute plants in the jute growing regions is to immerse the jute bundles in clear slow flowing water, in canals, rivulets, tanks, ponds or ditches.

The minimum ratio of plant material to water in stagnant water should be May 08,  · A comparative study between conventional and improved retting of jute (Corchorus olitorius L.

and C. capsularis L.) with a talc based microbial formulation was carried out for three consecutive retting trials in the same water during Due to introduction of the microbial formulation consisting of three different strains of Bacillus pumilus in the improved method, retting duration Cited by: 2.

There are three main stages of producing fiber from industrial hemp – harvesting, retting and separation. Harvesting. The quality of hemp fibre depends greatly on whether the crop was grown primarily for textiles, or is dual-purpose.

Dual purpose crops produce fiber and seed; with the seed being used for food, biofuels and other applications. May 02,  · Short video showing retting and scutching of jute in fields near Kolkata. Jute - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting.

Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. Retting is a preferential rotting process to separate the fibre from woody stem without damaging the fibre by: This page was last edited on 21 Mayat Files are available under licenses specified on their description page.

Jute is one of the most affordable natural fibers and is second only to cotton in amount produced and variety of uses of vegetable fibers.

Jute fibers are composed primarily of the plant materials cellulose and lignin. Jute is the name of the plant or fiber that is used to make burlap, hessian or gunny cloth.

During the last 30 years, various new technologies have been developed and introduced in China for the cultivation and retting of fibre crops (jute and kenaf) which have definitely contributed to the high production of these crops.

Some of these technologies (crop rotation, intercropping, fertilizer management, spacing, and retting) are dealt M. Basak. Define retting. retting synonyms, retting pronunciation, retting translation, English dictionary definition of retting.

Much research has been done so far on retting of jute but still the jute growers face various practical difficulties in implementing the proper procedure for retting.

May 01,  · Decorticated kenaf stalks were retted by bacterial and chemical processes. Bacterial retting was done in troughs at a temperature of 30 ± 2°C. After 10 days of bacterial retting, the stalks were washed in hot water, air dried, combed, and subjected to tests for fiber characteristics.

The main constraint in jute retting is the lack of available retting water. A portable ribboner machine which can strip off the bark from the harvested jute plants before retting has been designed and developed so as to facilitate the retting of green ribbons in smaller volume of water conveniently and produced fibre of improved quality.

Jute is a rain-fed crop with little need for fertilizer or pesticides, in contrast to cotton's heavy requirements. Production is concentrated in India and some in Bangladesh, mainly Bengal. The jute fibre comes from the stem and ribbon (outer skin) of the jute plant.
