This also reduces environmental pollution to a great extent. Results indicated that storage modulus was decreased for all composites with increases the temperature and pattern of slopes for all composites had almost the same values of E' at glass transition temperature (Tg). The new method of retting launched has been recognized as ribbon retting. Genera of bacteria and fungi isolated in jute fibre samples from both the jute mills are mostly similar which indicates that only a small group of microorganisms is active in jute bins/piles and they originate from the common source, i.e. Most of the defects arising from conventional retting could be overcome by ribbon retting. The retting process consists of bundling jute stems together and immersing them in slow running water. It seems that steaming in combination of compressing at high temperature would enhance the properties of OPTs. Bamboo culms were processed using microorganisms, and fibre bundles were obtained. This may lead to the formation of several decomposition products like organic acids (acetic, lactic, galacturonic and butyric acid). A publication of the Indian Jute Industries Research Associa-tion, Calcutta. The revision step is a process of its own and there’s no “right” number of revisions that produces strong writing. Calcium ions adsorb in a large quantity Pulp yield of conventional retted jute fiber and jutestick was higher at any kappa number. In biological retting, the stalks which are harvested are arranged in bundles and allowed to soak in water for about 20 days, ... Based on pectinolytic and xylanolytic activities 10 bacterial isolates were selected for retting consortia. Therefore, Bangladesh Government has introduced ribbon retting method in different areas of the country to ease peeling of jute fiber. Retting microbes consume the non-fibrous cementing materials mainly pectin and hemicellulose. Training provided to develop human resources and economic capacity were not useful for fishers or had little lasting effects on fisheries development due to poor monitoring and a disconnection with the needs of local users. Jute became an important export from the countries that produced it. • Conventional retting practice emits a little bit more nutrients, biogas and residues to the air and water A total of 451 bacterial colonies have been isolated from five jute retting water samples in Bangladesh. Though they are very effective as far as their end application is concerned, the availability of those fibres in the near future may get reduced due to depletion of natural resource, i.e., petroleum oil. Also, it advocates farmers for growing okra plant for additional income generation, while preventing the production of greenhouse gases during burning (commonly practiced). There are two types of retting: stem and ribbon. Results inferred that 15 days retting gives better quality of fibers. developed jute retting techniques, covering jute ret with water hyacinth, ribboning and ribbon- retting technique (for water scarce areas) etc. Ribbon retting conducted in cement retting tank was faster than that in polythene tank. But use of efficient pectinolytic microbial inoculum improves quality of fibre, further reduce the time of retting and the environmental pollution. Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. The fibers are first extracted by retting. Founded in pragmatism and viewing co-management through a governance lens, a comparative case study method was used that combined both qualitative and quantitative research approaches for data collection and subsequent analysis. were comprehensively reviewed to find out suitable methodology. The retting process is completed in 8 to 30 days, when the barks separate out easily from the stick or wood and the fibres are ready for extraction. The vertical and horizontal UL-94 test conducted and showed pure phenolic is highly fire resistant. Moreover the wash water arising due to rinsing of retted fibre was recycled, thereby achieving a zero discharge concept. It has been widely used as seasoning and condiments in food preparation. The optimum retting period was judged based on the characteristics of the retted fibre with respect to fibre fineness, tenacity, modulus, strain at break and linear density. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. The objective of this work was to prepare a steamed treated compressed OPT lumber and evaluate the physical, chemical and biological properties of modified wood. Jute - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. The retting of jute and mesta */a review. It answers the question of how supportive were the capacity development tools used in implementing co-management. In our study, a mixed bacterial retting culture, developed in our institute, was inoculated during ribbon retting of jute. Jute and kenaf are among the annually renewable fibre crops mainly grown over tropical and subtropical Asian countries. When the jute stalk is well retted, the stalk is grabbed in bundles and hit with a long wooden hammer to make the fiber loose from the jute hurd or core. The farmers are involved in jute cultivation and majority of them use the traditional method and time consuming approach of retting in ponds/canals. After the retting process, stripping of the fibre begins After the requisite period, the stems and ribbons were washed to extract the fibres. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography etc. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. Jute fibre is the second most important fibre next to cotton. In ribbon retting barks are removed from jute and kenaf plants mechanically or manually in the form of ribbon. Jahan et al. Jute retting process is one of the important responsible factors for quality of jute fiber. Ribbon retting of jute - a prospective and eco-friendly method for improvement of fibre quality. rice, wheat, maize, sunflower and mach more. Haque et al. Jahan et al. Present address: Crop Research Institute for Jute and Allied Fibre, ICAR, Barackpore, India. After the retting process, stripping begins women, children usually do this job. Throughout training sessions there were instances where technology was introduced without attention to its usefulness for farmers and fisher groups. However, few study on PALF have been done describing the interfacial adhesion between fibres and reinforcement compatibility of fibre but a detail study on PALF properties is not available. Transgenic lines exhibited reduced level of gene expression with ~ 16–25% reduction in acid insoluble lignin for the whole stem and ~13–14% reduction in fiber lignin content compared to the control lines. DCE-01 secretes key degumming enzymes: pectinase, mannase, and xylanase, which match well the main non-cellulosic components of jute bast. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. No significant change in strength and fineness of fibre has been observed due to 48 h of piling. Jute is an eco-friendly and bio-degradable natural product with no adverse effect on the environment. The change in chemical composition due to alkali treatment was determined using Fourier transmission infrared spectroscopy and chemical composition analysis. ... For bacterial degumming, some researchers have studied the screening and community structure of degumming bacterial strains of jute (Banik et al. Mechano-microbial Retting Mechano-microbial retting of jute involves two distinct operations viz. This article focusses on the microbial retting of jute bast fibres under aerobic condition using sequencing batch reactor. Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. By retting, the fibres are first removed. Even though fibers were almost detached from the corn leaves in case of 20 days of retting, the fibers were found to be weak. Jute retting process is one of the important responsible factors for quality of jute fiber. Transgenic generations, analyzed through Southern, RT-PCR and northern assays showed downregulation of the selected genes. The fibres are first extracted by retting. There are two types of retting: stem and ribbon. Chemical composition analysis of the fibre bundles obtained showed that the components are mainly cellulose, hemicelluloses and lignin. callistephi race 3 are reported. Ribbon retting reduces time of normal retting by 4–5 days. Traditional processes are outdated which should be modified according to the technological advancement. After the retting process, stripping begins. Science and Culture 44, 379 Á/381. The bacterial isolates are mostly Gram-positive rods of the genus Bacillus, Gram-positive coccus of the genus Micrococcus and Gram-positive filamentous rods of the genus Streptomyces. Retting is a microbiological process and, therefore, the end-point is determined by inspecting a few plants each day from the tenth day onward. Globally, white pepper fetches a higher price compared to black pepper due to its lighter colour, preferable milder flavour and pungency. This fertile geographic region is shared by both Bangladesh and India (mainly West Bengal). Pentosan, extractive and ash contentin ribbon retted jute fiber and jute stick were higher and lignin and �-cellulose content were lower thanthe conventional retted jute fiber and jute stick. The retting process consists of bundling jute stems together and immersing them in … Kena fbast fibers were extracted using different methods (crude, decorticated, water retted, 5% sodium hydroxide retted and 5% benzoate retted) and their physicochemical characteristics were investigated. This vermicompost from pineapple leaf agro-waste is found to be rich in plant nutrients. quality fibres, but it is quite expensive. Further explaining the process, a DAE official said that, firstly raw ribbon will be separated from the jute sticks with the help of ribbon retting machines. Direct penetration of host cell secondary walls by the pathogen occurred, but these were degraded to any extent only following intramural invasion. Characteristics of Jute Fibre: Jute is a long, soft, shiny fibre that can be spun into coarse, strong threads. All rights reserved. Amongst the bast fibre crops, kenaf apparently has some advantages such as lower cost of production, higher fibre yields, and greater flexibility as an agricultural resource, over the other bast fibres. Ribbon retting reduces time of normal retting by 4–5 days. This also reduces environmental pollution to a great extent. The retting process consists of bundling jute stems together and immersing them in slow running water. has apparent advantages over the retting processes by having significantly shorter retting time and acceptable The jute is taken from the stem and the skin of the stem, which is called the ribbon. Therefore, forgetting quality jute fiber, a low cost ribbon retting technique is essential and farmers could able to produce high quality jute fiber.

The modern manufacturing industry is facing a great number of challenges to establish green sustainability to lessen the threats formed by decadent civilization gradually for years, is the issue itself to solve with proposed solutions from all over the world can invite further unrecognized problems which may leave the situation unbearable. June, 2015 Jute retting process: present practice and problemsin Bangladesh Vol. The bacterial isolates are mostly Gram-positive rods of the genus Bacillus and fungi mainly of the genera Aspergillus and occasionally Penicillium. The residual green sludge has been used for vermicomposting after appropriate treatment using earthworm species African night crawler (Eudrilus eugeniae) as inoculums. This work shows that optimized degumming processes could be achieved using this model by avoiding time‐consuming and costly trial‐and‐error tests. from the stem. Jute is one of Bangladesh’s main cash crops. The retted fibres were then degummed and bleached for better processibility and aesthetic look. The fibres are then covered by Ca(OH)2 nodules after immersion in a lime solution. Ribbon retting requires lesser volume of water, lesser time, creates lesser environmental pollution, and produces improved quality fibre. In the retting tank, use of pectinolytic microbial inoculums could be introduced to improve quality of fiber and reduce the time of retting, ... Additionally, polluted water containing chemicals as pesticides and fertilizers increases the risks. ABSTRACT The jute industry is facing severe competition from synthetic packaging materials in the present situation. A microbial consortium consisting of three bacterial strains isolated from jute retting water with very high polygalacturonase (PG) (5.1–6.0 IU/ml), pectin lyase (PNL) (185.7–203.7 U/ml), xylanase (15–16.2 IU/ml) activity, but devoid of any cellulase activity was used for jute and mesta retting under controlled and farmers’ field conditions. Both over retting and under retting which are very difficult to control causes production of low grade jute fibre. In contrast with the ribbon retting of jute (Banik et al. But use of … The retting process consists of bundling jute stems together and immersing them in slow running water. The presence of theses acids in retting water may lead to the reduction of pH, ... To get the average lignin value of a plant, only the mid-section (~16 cm) of the stem was used in this study. Modle No: 786-06 Fabric: Natural laminated 13*13 jute. Tables of content are generated automatically and are based on records of articles contained that are available in the TIB-Portal index. The main purpose of this study was provided information about the status of present jute retting process as well as mentioned the advantages and disadvantages of different jute retting processes. The organisms could be adopted in industrial application for extraction of jute fibre. Jute is a natural fiber that is mainly grown across West Bengal in India and in Bangladesh with some also grown in Myanmar, Uzbekistan This treatment, Light and transmission electron microscope studies of naturally infected or inoculated staghorn sumac plants by Fusarium oxysporum f. sp. Bangladesh: Ribon Retting of Jute and it’s importance. In 1855 Calcutta became the site of Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. This is called ribbon retting. Effectof ribbon retting on kraft pulping was also studied. Decreasing lignin in such plants holds significant commercial and environmental potential. There are two types of retting: stem and ribbon. Paul, N.B., Bhattacharyya, S.K., 1978. Natural fibre based composites are under intensive study due to their eco-friendly nature and peculiar properties. The retting of jute and mesta */a review. Its various mechanical testing characterization values, including tensile strength, spilt tensile strength, flexural strength, impact strength, peeling test, and compressive strength, represent benchmarks compared with other, currently available natural fibers. Usually mature stems of harvested jute plants are … Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. The well-explored natural fibres have limited availability in terms of quantity and those cannot fulfil the total requirement of fiber applications. Furthermore, it summarizes the recent work reported on physical, mechanical and thermal properties of PALF reinforced polymer composites with its potential applications. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. The traditional methods of retting namely water retting and dew retting suffered from several limitations like poor quality of fibers, comparatively large space and time requirement, dependence on weather conditions, huge manpower involvement, pollution and high cost of drying. You can request the full-text of this article directly from the authors on ResearchGate. Advantages of Ribbon Retting • Lesser amount of water is required for retting. 2003;Munshi and Chattoo 2008). In contrast with the ribbon retting of jute (Banik et al. The retting process consists of bundling jute stems together and immersing them in slow running water. Here all possible methods of fiber extraction like different retting ii) Retting of green ribbons with microbial consortium. Retting microbes consume the non-fibrous cementing materials mainly pectin and hemicellulose. The three isolates were identified as different strains of Bacillus pumilus, which were designated as PJRB1, PJRB2 and PJRB3 by ribotyping of a 977 bp fragment. The retting process consists of bundling jute stems together and immersing them in low, running water. Peak of loss modulus of pure phenolic showed very less, after the addition of kenaf/PALF peaks were higher and shifted towards high temperature. Retting operation was carried out for varying time period namely 10, 15, 20, 25, 30 and 35 days respectively. Fine filamentous structures, connected to fungal cells, to the vessel lining matter, and to these other elements, extended into host walls. A post-retting treatment has also been developed at this Institute to upgrade lower qualities of jute fibre produced by the ribbon retting route and freshly extracted from the retting tank. water are also used for retting. The present paper reviews the important attributes of underexploited okra plant as a fibre source for various textile applications. The variability in types of natural fibers, different retting methods, intervention of microbial enzymes for retting of fibers, parameters for efficient retting aresome of the important highlights of this review. These differences were pronounced for jute stick. The alkali treatment resulted in the removal of lignin, fats, and waxes as well as the disintegration of individual fibers from the retted fiber bunch.

It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. Among industrial fiber crops, jute is ranked second to cotton in terms of yield and planting area worldwide. The fibers are first extracted by retting. It is expected that successful COMT-hpRNA and C4H-hpRNA transgenesis in jute will have far-reaching commercial implications leading to product diversification and value addition. processes, namely, dew, water, enzymatic, mechanical, and chemical retting, mechanical and alkali methods The stalk stays submerged in water for 20 days. Bacterial and fungal populations in piled jute samples of Bharat Jute Mill are found to be in the order of 10 8 and 10 5 per gram of fibre, while the same in Budge Budge Jute Mill are in the order of 10 5 and 10 3 per gram of jute fibre respectively. Microbial inoculation produced remarkable improvement in jute fibre strength (26.62–28.91 g/tex) and fineness (2.76–2.92 tex) over control. Cultivation is dependent on the climate, season, and soil. The introduction of biotechnology approach has gain a lot of interests, as it is a more rapid, convenient and hygienic method of producing white pepper. In: Proceedings of International Seminar on Jute and Allied Fibres */Changing Global Scenario. In Indian subcontinent, pineapple leaves are wasted after harvesting the fruit, because of technology gap exists in the efficient extraction and lack of knowledge of subsequent processes for value addition to the fibre. “Review of bast fiber retting,” BioResources 6(4), 5260-5281. After the retting process, stripping begins; women and children usually do Ribbon retted fibre with pectinolytic mixed bacterial culture in combination with urea obtained higher grade in comparison to uninoculated control. Retting of green ribbon with microbial retting ormulatiof n 5.1.3. From the present study it is understood that inoculation of a specific mixed bacterial culture in combination with 0.5% urea as N-supplement caused faster ribbon retting of jute and kenaf. Ribbon retting has the following advantages over conventional retting: (1) It requires lesser volume of water, (2) it is faster, (3) it produces lesser environmental pollution, and (4) it produces improved quality fibre. Out of these, 168 isolates have been screened by both semi-quantitative and quantitative pectinase, xylanase and cellulase enzyme assay. Women and children usually do this Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. The retting process consists of bundling jute stems together and immersing them in slow running water. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. Ribbon retting reduces time of normal retting by 4–5 days. The overall results showed that treated KF composites enhanced the dynamic mechanical and thermal properties among all PALF/KF composites. Indian agriculture is producing very large quantity, approximately 500 million tonnes of crop Depending on samples, fibre strengths Stelometer are equal to or considerably greater than dew retted ‘cottonized flax or typical cotton fibres. Bundling jute stems together and immersing them in slow running water consists of the retting process. Ribbon retting reduces time of traditional retting by 4-5 days as well as reduces requirement of water, 55) Figures in parenthesis indicate inoculation of mixed bacterial culture Retting and extraction of jute problems and prospects. Such ribbon retted fibres produced standard and regular quality yarn. This was due to longer time of retting in the conventional retting process removed more pentosan. Mucor has been found only in Bharat Jute Mill and Chaetomium is found only in Budge Budge Jute Mill fibre samples. The 16S rDNA analysis revealed that the organisms were: Bacillus sp. The fibers were subjected to alkali treatment in order to enhance the mechanical as well as handle properties. In this process the defoliated jute bundles (50kg) are immersed in a tank or confined water bodies with ratio of plant to water is 1:2. (Ed. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. Indian Agriculturist 31 (I), 49 Á/52, Paul, N.B., Basak, M.K., 1987. After the retting process… Jute - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Vessel walls, at all stages of infection, were lined with variously structured matter: in their thinnest forms, by single or paired, equidistant or widely spaced opaque bands, and in their thickest forms as alternating opaque and less opaque layers. These elements were sometimes observed to be confluent with fungal cells and to label for chitin. Merits of in-situ 6. Raw jute in the form of bales are processed in jute mills to produce hessian, sacking, jute yarn, bags, and other useful products. Retting Process | Methods of Retting | Advantages and Disadvantages of Retting Methods Flax |Production Region of Flax | Cultivation of Flax | Chemical composition of Flax Morphological structure of Jute … Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process. In actual practice the fungal … The farmers are involved in jute cultivation and majority of them use the traditional method and time consuming approach of retting in ponds/canals. Our findings indicate a needsbased approach to capacity building is needed in order to support the livelihoods of local users through co-management. There are two types of retting, stem and ribbon. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances. Whole plant retting of jute and mesta with microbial consortium under controlled conditions reduced the retting duration by 7 days for jute, with improved fibre quality i.e. Jute retting process is one of the important responsible factors for quality of jute fiber. 5th and 6th February 1998, Calcutta, A NIRJAFT publication. Today, pineapple fiber is enormously popular among the composite research community due to its various advantages including its smoothed and scaled morphology, low thickness, firmness, reduced weight, and superior mechanical properties. Data book on jute, 1999. Present study deals about dynamic mechanical, thermal analysis and flammability of treated and untreated pineapple leaf fibre (PALF) and kenaf fibre (KF) phenolic composites. • Raw jute in the form of bales are processed in jute mills to produce Hessian, sacking, jute yarn, bags, and other useful products. This also reduces environmental pollution to a great extent. Ribbon retting … As jute made products are getting popular worldwide, steps are to be taken to comply with the demand of customers and conservationists. different agriculture based biowaste sources. leads also to the decrease of the cristallinity index of the cellulose. Similarly labelled opaque bodies occasionally occurred on vessel walls and lumina. would be the product of extraction of all possible agriculture based bio-waste, crop residues, stalks, straw etc of The jute fiber comes from the stem and ribbon (outer skin) of the jute plant.
