retting of jute by C. G. Jarman Download PDF EPUB FB2

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.

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.

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.
