The change in chemical composition due to alkali treatment was determined using Fourier transmission infrared spectroscopy and chemical composition analysis. June, 2015 Jute retting process: present practice and problemsin Bangladesh Vol. An 18 month study was conducted and six cases were investigated to understand the approaches to co-management programs used to develop local capacity. The retting process consists of bundling jute stems together and immersing them in slow running water. 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. Decreasing lignin in such plants holds significant commercial and environmental potential. Mechano-microbial Retting Mechano-microbial retting of jute involves two distinct operations viz. The retting process consists of bundling jute stems together and immersing them in slow running water. Indian Agriculturist 31 (I), 49 Á/52, Paul, N.B., Basak, M.K., 1987. These elements were sometimes observed to be confluent with fungal cells and to label for chitin. The pH of the post-retting water samples became acidic, and the electrical conductivity (Ec), chemical oxygen demand (COD) and hardness increased. 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. human resource and economic development) to enhance local capacities. quality fibres, but it is quite expensive. Calcium ions adsorb in a large quantity / Industrial Crops and Products 17 (2003) 183 Á/190, Effect of inoculation of harvested green jute plants with bacterial retting cultures on period of retting and quality of jute. The retting process consists of bundling jute stems together and immersing them in slow running water. Present study deals about dynamic mechanical, thermal analysis and flammability of treated and untreated pineapple leaf fibre (PALF) and kenaf fibre (KF) phenolic composites. Many fungal elements were bound by only a thin or defective lucent wall layer, practically unlabelled for chitin, or by a locally thick- ened, labelled one; labelling for this substrate was also frequently associated with the fungal cell outer opaque wall layer or with some outer extracellular matter. Environmental Scanning Electronic Microcopy of the fibre bundles (retted) showed great fibre sensibility towards moisture, which could significantly influence mechanical properties. This review highlights both conventional and latest biotechnological processes of white pepper production. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. 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. You can request the full-text of this article directly from the authors on ResearchGate. Malaysia is one of the biggest producers of palm oil in the world but the oil palm wood is considered as waste after final harvesting. Ribbon retting conducted in cement retting tank was faster than that in polythene tank. The fibers are first extracted by retting. The retting process consists of bundling jute stems together and immersing them in … A publication of the Indian Jute Industries Research Associa-tion, Calcutta. (/267 ((/266) (55) Figures in parenthesis indicate inoculation of mixed bacterial culture. Jute retting process is one of the important responsible factors for quality of jute fiber. The retting process consists of bundling jute callistephi race 3 are reported. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Consideration is given to external loading and molecular characterization and crystallography of pineapple fiber to better understand its mechanical and thermal behavior. or biologically (Rahman, 2010). The combined technology package for the extraction of fibre from pineapple leaf and utilization of the residual biomass debris from the pineapple leaf scratching machine forvermicomposting is economically viable and remunerative for the pineapple cultivators. During the storage of fish, dynamic primary changes are taking place in numerous parts of the fish, including the eyes, skin, gills and muscle characteristics of the fish. Bamboo culms were processed using microorganisms, and fibre bundles were obtained. The objective of this study was to investigate the effect of different extraction methods on the fiber morphology, density, chemical composition and tensile strength of kenaf bast fiber. In contrast with the ribbon retting of jute (Banik et al. Retting of green ribbon with microbial retting ormulatiof n 5.1.3. 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. There are two types of retting: stem and ribbon. However, the retting process may require less time if the quality of the jute is better. The paper also reviews the methods of extraction of okra fiber by retting, and its physical, chemical and tensile properties were compared with similar well-explored lignocellulosic jute fiber. The retting process consists of bundling jute stems together and immersing them in low, running water. The retting process consists of bundling jute stems together and immersing them in low, running water. All the isolated bacteria as well as fungi possess pectinolytic activity. Some jute was brought to Dundee, Scotland where eventually a process was designed to spin jute yarn in large volumes. Merits of mechano-microbial retting 5.1.4. Composition of the lignin building blocks was found to alter and this alteration resulted in a pattern, different from other plants where the same genes were manipulated. fibre quality through retting. The retting of jute and mesta */a review. Retting microbes consume the non-fibrous cementing materials mainly pectin and hemicellulose. Jahan et al. Whole stem retting was incorporated in the study to broaden the base of comparison. Natural fibre based composites are under intensive study due to their eco-friendly nature and peculiar properties. were comprehensively reviewed to find out suitable methodology. Eventually resulting in development of disease development and fruit decay in harvested longans during storage at 28°C. Fine filamentous structures, connected to fungal cells, to the vessel lining matter, and to these other elements, extended into host walls. In ribbon retting barks are removed from jute and kenaf plants mechanically or manually in the form of ribbon. Christmas tree ribbon decorations are just the finishing touch to make your tree holiday-ready. Ribbon retting reduces time of normal retting by 4–5 days. In-situ retting of jute & mesta with microbial formulation 5.2.1. Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. Merits of in-situ 6. Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. Retting is the main challenge faced during the processing of bast plants for the production of long fibre. Ribbon retting reduces time of normal retting by 4–5 days. The traditional water retting and chemical semi-degumming methods restrict the development of the jute industry. Both over retting and under retting which are very difficult to control causes production of low grade jute fibre. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. The, The main goal of this study was to investigate the influences of Phomopsis longanae Chi infection on activities of cell wall-degrading enzymes (CWDEs), and contents of cell wall components in pericarp of harvested “Fuyan” longan (Dimocarpus longan Lour. They're also a Christmas craft that is simple to make, and the style options are endless.. First, choose a good-quality ribbon. In 2011 Bangladesh Government has introduced ribbon retting method in different areas of the country to ease peeling of jute fibre. The well-explored natural fibres have limited availability in terms of quantity and those cannot fulfil the total requirement of fiber applications. In order to decrease kenaf chemical residues and environmental pollution caused by conventional degumming methods, the present work used a biological enzyme degumming technique to degum kenaf, where the enzyme was the secretion from Aspergillus niger‐kenaf. The results showed that, compared with the control samples, P. longanae-inoculated, Chemical reactivity of hemp fibres placed into a cimentitous matrix was studied by using a lime solution as a simplified cement Ribbon retting reduces time of normal retting by 4–5 days. Most of the defects arising from conventional retting could be overcome by ribbon retting. Efficient pectinolytic bacteria as well as fungi could be used in retting process. The predominant microbial species present in the jute retting liquor were found to be species of Bacillus, Clostridium, Aspergillus and Mucor. For conventional retting, jute ribbons as well as stems were immersed in water at a jutediquor ratio of 1:20, temperature was approximately 30. The fibres are then covered by Ca(OH)2 nodules after immersion in a lime solution. 5 Proofreading When you feel confident about your revisions, move on to the last writing process step: proofreading. Retting is a microbiological process and, therefore, the end-point is determined by inspecting a few plants each day from the tenth day onward. The fibers are first extracted by retting. The bleachability of jute fiber pulp was better than that of jute stick pulp.Conventional retted fibers showed slightly better bleachability. They are possibly the world's largest source of lignocellulosic bast fibre which is extracted from plants by a natural microbial process known as retting. In the conventional retting, jute plant is immersed in clear slow flowing water for 14–28 days to degrade the pectic materials, hemicellulose, and lignin. Raw jute in the form of bales are processed in jute mills to produce hessian, sacking, jute yarn, bags, and other useful products. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. Peak of loss modulus of pure phenolic showed very less, after the addition of kenaf/PALF peaks were higher and shifted towards high temperature. So there is a global need to search and explore new underexploited, but commercially important natural fibres. / Industrial Crops and Products 17 (2003) 183 Á/190 References Alam, A., 1998.

Jute became an important export from the countries that produced it. Retting microbes consume the non-fibrous cementing materials mainly pectin and hemicellulose. Bundling jute stems together and immersing them in slow running water consists of the retting process. Bag Size: Height-37cm, Width-35cm, Gusset-18cm. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. However, the bio-degumming of jute does not require strong acid and strong base and is characterized by gentle degumming technological conditions, high efficiency, high quality, and low pollution. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. 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. 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. Indian Agriculturist 31 (I), 49 Á/52. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. Other thin elements, often enclosing opaque material, vesicular structures, or occasionally particles of riboso- mal appearance were also delineated by similar but frequently infolded bands. Fungal isolates are mainly of the genera Aspergillus and, to a lesser extent, of the genus Penicillium and Dendrophoma. In conventional retting, a huge biomass undergoes decomposition in stagnant water, so retting causes environmental pollution. A number of other alternative methods such as mechanical decortication, chemical, heat, and enzymatic treatments have been reported for this purpose with mixed findings. In most cases, the fiber extraction process of bast fibers in water retting is done by the farmers while standing under water. The mechanical, physical strength and chemical compositions of natural fibers strongly depend on harvesting, climate, location, soil characteristics and weather circumstances. Ribbon retted fibre with pectinolytic mixed bacterial culture in combination with urea obtained higher grade in comparison to uninoculated control. Advantages of Ribbon Retting • Lesser amount of water is required for retting. • Conventional retting practice emits a little bit more nutrients, biogas and residues to the air and water So, ribbon retting is a great promise to produce high quality jute fibre in one hand and a more eco-friendly measure on the other. The farmers are involved in jute … Mechanical properties of thread were found to be suitable to make sustainable novelty fabrics for apparel. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. introduced ribbon retting in Bangladesh for jute-retting process. This study aimed at reducing the lignin content in jute-a fiber crop, by introducing hpRNA-based vectors for downregulation of two monolignoid biosynthetic genes- cinnamate 4-hydroxylase (C4H) and caffeic acid O-methyltransferase (COMT). The study shows that corn leaf fiber has good potential in technical textile applications. 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. Haque et al. Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances. L6 (GQ891097), Bacillus pumilus strain EK-17 (GQ891098), B. pumilus strain Geo-03-422 (GQ891103) and B. pumilus strain IK-MB12-518F (GQ891105). The results suggested that the P. longanae stimulated-disease development of harvested longans was due to increase in activities of pericarp CWDEs, which might accelerate the disassembly of pericarp cell wall components. [] introduced ribbon retting in Bangladesh for jute-retting process. Even though the fibres produced from water retting can be of high quality, the long duration and polluted water have made this method less attractive. Out of these, 168 isolates have been screened by both semi-quantitative and quantitative pectinase, xylanase and cellulase enzyme assay. Data book on jute. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. Jute fiber can be extracted from jute bast through mechanical rolling (preprocessing), culture of bacteria, soaking fermentation (liquor ratio = 10, inoculum size = 1 %, temperature = 35 °C, and time = 15 h), inactivation, washing, and drying. Pineapple leaf fibre of certain varieties is widely used in Philippines for making apparels. These include the soil, retting, and jute genotype. Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process. The retting of the ribbon is called ribbon retting. 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. To read the full-text of this research, you can request a copy directly from the authors. Whole sterns were retted for 14 days and ribbons for 9 days. The morphological characteristic were visualized based on the scanning electron microscope image. 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. Bundle strength, elongation, and moisture properties were found to improve after chemical treatment. To check the synergistic and antagonistic effect 10 selected isolates were tested in 167 different combinations. After the retting process, stripping begins. As jute made products are getting popular worldwide, steps are to be taken to comply with the demand of customers and conservationists. Compared with the traditional water retting degumming, the bio-degumming cycle is shortened from more than 10 days to 15 h. The proposed bio-degumming achieved higher efficiency and lower pollution than water retting and chemical semi-degumming. Ribbon retting of jute - a prospective and eco-friendly method for improvement of fibre quality. They were air dried … The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. In ribbon retting, barks are removed from jute in the form of ribbon. 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. Almost 85% of the world's jute cultivation is concentrated in the Ganges Delta. The process of retting is further accelerated by the application of a chemical accelerator formulated by National Institute of Research on Jute and Allied Fibre Technology, Kolkata. The most common conventional method is water retting but can also include pit soil, chemical, boiling, steaming and mechanical methods. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. The retting of jute and mesta */a review. In this technique OPT samples were steamed at temperature 130 °C for 2 h before being compressed at high temperature. The microbial enzymes predominately pectinases are becoming popular for retting of fibers owing to the fact that it results in high quality fiber, save time and is also ecofriendly. 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. Similarly labelled opaque bodies occasionally occurred on vessel walls and lumina. Future research needed in this respect has been expressed. 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. The fibres produced from kenaf using chemical retting processes are much cleaner but low in tensile strength. is ideal. Among industrial fiber crops, jute is ranked second to cotton in terms of yield and planting area worldwide. Lignin, a cross-linked macromolecule of hydrophobic aromatic structure, provides additional rigidity to a plant cell wall. In water retting, the stalks are dipped in tanks filled with freshwater, where a pectin degrading bacterial community influences the retting process [32].
