Haque et al. In 1855 Calcutta became the site of Bacterial population in raw C. capsularis jute is found to be in the order of 10 4 per gram of jute fibre and that in raw C. oliforius jute is in the order of 10 5 per gram of jute fibre. There are two types of retting: stem and ribbon. Jute is a cash crop of Bangladesh, which is extracted from jute plant by retting process. Basic methods include dew retting and water retting. In ribbon retting barks are removed from jute plants in the form of ribbon. Two forms of This improved retting technology can be adopted in industrial scale for the production of quality jute fibre in a controlled condition in reduced water quantity without polluting the environment. This study presents a post-facto evaluation of the local capacity development processes used under co-management of fisheries and other resources of southern Bangladesh. After … The ribbons are coiled and then allowed for retting in water. Eventually resulting in development of disease development and fruit decay in harvested longans during storage at 28°C. or biologically (Rahman, 2010). This indicates that the piling microbes might play a significant role in remoling residual pectin from the fibre during piling of jute. The organisms in different combinations of consortia reduced the ret-ting period from 11 to 13 days as compared to 19 days in the control. Throughout training sessions there were instances where technology was introduced without attention to its usefulness for farmers and fisher groups. This may lead to the formation of several decomposition products like organic acids (acetic, lactic, galacturonic and butyric acid). 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. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. S. Banik et al. For retting gently flowing, fairly deep, clear and soft water. In: Proceedings of International Seminar on Jute and Allied Fibres */Changing Global Scenario. 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. Bose, R.G., 1969. In contrast with the ribbon retting of jute (Banik et al. / 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. Microbial inoculation produced remarkable improvement in jute fibre strength (26.62–28.91 g/tex) and fineness (2.76–2.92 tex) over control. 2003), during jute degumming process of bacterial strain DCE-01, within 12 h, pH is kept acidic while ORP kept being greater than 0 namely under aerobic status, at 15 h, pH The retting process consists of bundling jute stems together and immersing them in slow running water. Transgenic generations, analyzed through Southern, RT-PCR and northern assays showed downregulation of the selected genes. The bleachability of jute fiber pulp was better than that of jute stick pulp.Conventional retted fibers showed slightly better bleachability. colour, lustre, fibre strength (27.0–28.1 g/tex, fineness (2.7–2.8 tex) and fibre recovery by 13.8–15.24 % over control. 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 physico-mechanical properties of the retted and alkali-treated corn leaf fibers were analyzed using various analytical and statistical methods. The present paper reviews the important attributes of underexploited okra plant as a fibre source for various textile applications. There are two types of retting: stem and ribbon. The retting process consists of bundling jute stems together and immersing them in slow running water. Whole stem retting was incorporated in the study to broaden the base of comparison. On the other hand, increased lumen diameter and a decreased cell wall thickness were observed with the decorticated and water retted bast fibers. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. (2011). Here, a review work has been done to get an eco-friendly fiber which Ribbon retted fibre with pectinolytic mixed bacterial culture in combination with urea obtained higher grade in comparison to uninoculated control. The traditional water retting and chemical semi-degumming methods restrict the development of the jute industry. Pulp yield of conventional retted jute fiber and jutestick was higher at any kappa number. The retting process consists of bundling jute Now-a-days a particular method is getting popular called ribbon retting which reduces time of traditional retting by around a week as well as requires less water where jute fibers are stripped out mechanically in ribbon form and then coiled and immersed in water, ... important factor in retting. 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. In addition, pineapple fiber is completely/partially biodegradable and recyclable, cheap to produce, and easy to make. 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 were comprehensively reviewed to find out suitable methodology. 17, No. It indicates that retting of corn leaves for longer periods leads to degradation of fiber, maybe because of microbial action, ... Extracted fibres are dried in hanging place by air. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. 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. The farmers are involved in jute cultivation and majority of them use the traditional method and time consuming approach of retting in ponds/canals. 2012;Haque et al. After the retting process, stripping begins; women and children usually do In the stripping process, non-fibrous matter is scraped off, then the workers dig in and grab the fibres from wit… 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. 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. June, 2015 Jute retting process: present practice and problemsin Bangladesh Vol. The residual green sludge has been used for vermicomposting after appropriate treatment using earthworm species African night crawler (Eudrilus eugeniae) as inoculums. Data book on jute. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. The retting process consists of bundling jute stems together and immersing them in slow running water. As jute made products are getting popular worldwide, steps are to be taken to comply with the demand of customers and conservationists. Basic methods include dew retting and water retting. The mechanical, physical strength and chemical compositions of natural fibers strongly depend on harvesting, climate, location, soil characteristics and weather circumstances. The enzymatic retting is now preferred over the traditional methods resulting in formulation of several commercial enzyme preparations like Flaxzyme and Viscozyme. India is the highest producer of Okra in the world, but after okra harvesting, the stem mostly remains underutilized. The predominant microbial species present in the jute retting liquor were found to be species of Bacillus, Clostridium, Aspergillus and Mucor. Similarly labelled opaque bodies occasionally occurred on vessel walls and lumina. Enzymatic retting of jute ribbons. The morphological characteristic were visualized based on the scanning electron microscope image. 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. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. 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. Bacterial population in laboratory bins is found to be in between 10 6 and 10 7 per gram of jute fibre while fungal population is in between 10 4 and 10 5 per gram of jute fibre. After the retting process, stripping begins. Chemical composition analysis of the fibre bundles obtained showed that the components are mainly cellulose, hemicelluloses and lignin. The retting process consists of bundling jute stems together and immersing them in slow running water. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. Ribbon retting requires lesser volume of water, lesser time, creates lesser environmental pollution, and produces improved quality fibre. Demerits of mechano-microbial retting 5.2. In most cases, the fiber extraction process of bast fibers in water retting is done by the farmers while standing under water. Jute is a natural fiber that is mainly grown across West Bengal in India and in Bangladesh with some also grown in Myanmar, Uzbekistan, Thailand and china. In-situ retting of jute & mesta with microbial formulation 5.2.1. Mechano-microbial Retting Mechano-microbial retting of jute involves two distinct operations viz. 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. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. Depending on samples, fibre strengths Stelometer are equal to or considerably greater than dew retted ‘cottonized flax or typical cotton fibres. A publication of the Indian Jute Industries Research Associa-tion, Calcutta. The well-explored natural fibres have limited availability in terms of quantity and those cannot fulfil the total requirement of fiber applications. Thermo-gravimetric analysis (TGA) results indicated that pure phenolic have better thermal stability than PALF and kenaf phenolic composites. In actual practice the fungal … Bangladesh: Ribon Retting of Jute and it’s importance. After bundles of jute are. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. The methods of retting have witnessed technological advances based on intervention of microbial enzymes resulting in better quality of fibers. 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. An increase in cellulose and hemicelluloses content was detected along with a decrease in lignin content after bio-processing. These differences were pronounced for jute stick. 12, Regent Park, Kolkata-700040, India. ultimately or left in the field unutilized. Three best combinations were identified that lowered retting period from 18–21 days to 10 days producing high quality fibre in both laboratory and field trial. In contrast with the ribbon retting of jute (Banik et al. Wettability of the steam compressed OPT was analysed by contact angle method and observed it was reduced as compared to simply compressed OPT. But acute shortage of water for retting and the environmental pollution created from conventional system of retting has demanded for new method of retting.The new method of retting launched has been recognized as ribbon retting. Retting Environment • Jute assimilates about 5.8 ton CO2 from the atmosphere in its lifetime (Rahman and Bala, 2009). Retting is the main challenge faced during the processing of bast plants for the production of long fibre. In addition, the inoculation treatment with P. longanae significantly promoted the activities of CWDEs including pectinesterase, polygalacturonase, β-galactosidase, and cellulase. 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. The fibers are first extracted by retting. The overall results showed that treated KF composites enhanced the dynamic mechanical and thermal properties among all PALF/KF composites. To read the full-text of this research, you can request a copy directly from the authors. Lignin, a cross-linked macromolecule of hydrophobic aromatic structure, provides additional rigidity to a plant cell wall. After the retting process, stripping of the fibre begins The change in chemical composition due to alkali treatment was determined using Fourier transmission infrared spectroscopy and chemical composition analysis. This is followed by spraying with a fungal culture powder. Ribbon retting of jute - a prospective and eco-friendly method for improvement of fibre quality. Mucor has been found only in Bharat Jute Mill and Chaetomium is found only in Budge Budge Jute Mill fibre samples. 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. Jute Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. However, these strategies have achieved mixed results with regard to developing governance that supports livelihoods. 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. human resource and economic development) to enhance local capacities. : Retting of green jute ribbons (Corchorus capsularjs var ribbons An 7 days, rrjchoderma and Qurvujana took longer period of time (11 days) and other fungi showed insignificant progress of retting (Table IL Fiber strength of If ribbons are retted it is called ribbon retting. 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. Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. quality fibres, but it is quite expensive. The retting process consists of bundling jute stems together and immersing them in low, running water. Jute is one of Bangladesh’s main cash crops. After the retting process, stripping begins. Enzymatic retting has apparent advantages over other retting processes by having significantly shorter retting time and acceptable quality fibres, but it is quite expensive. Although it is an integral part of the plant cell, presence of lignin considerably reduces the quality of the fiber of fiber-yielding plants. Effect of efficient pectinolytic bacterial isolates on retting and fibre quality of jute, A proposal of sustainable and integrated plant for jute fiber extraction in an eco-friendly manner, Chemical characteristics of ribbon retted jute and its effect on pulping and papermaking properties, Bio-degumming technology of jute bast by Pectobacterium sp. 3. Jute became an important export from the countries that produced it. A number of other alternative methods such as mechanical decortication, chemical, heat, and enzymatic treatments have been reported for this purpose with mixed findings. Some of this material labelled for pectin, often in association with tyloses, as did other opaque matter in paratracheal, Access scientific knowledge from anywhere. 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. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Jute is an eco-friendly and bio-degradable natural product with no adverse effect on the environment. Higher pectinolytic bacterial isolates were predominant in the later stage of jute retting. Process The process of manufacturing a particular kind of thread can vary widely, from the spinning of silk to the carding and processing of wool. different agriculture based biowaste sources. Bundle strength, elongation, and moisture properties were found to improve after chemical treatment. 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 … The fibers are first extracted by retting. Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. It has been widely used as seasoning and condiments in food preparation. The ditches may be filled with clear water from tube well or from any other water sources. One hundred twenty-day-old plant was found most suitable for ribbon retting. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials. This work shows that optimized degumming processes could be achieved using this model by avoiding time‐consuming and costly trial‐and‐error tests. After the retting process… In turn, resulting in the degradation of pericarp cell wall, reduction of pericarp mechanical strength, and subsequently leading to the breakdown of longan pericarp tissues. Jute retting process is one of the important responsible factors for quality of jute fiber. 16 s ribosomal gene sequencing analysis identified 2 phyla- Firmicutis (80.55%) and Proteobacteria (19.45%). This study provides empirical evidence that co-management programs have applied a number of strategies (e.g. Retting is a microbiological process and, therefore, the end-point is determined by inspecting a few plants each day from the tenth day onward. There are two types of retting: stem and ribbon. introduced ribbon retting in Bangladesh for jute-retting process. • Raw jute bales from jute fields or suppliers, carried by trucks are unloaded are stacked in the jute mills godown. Environmental Scanning Electronic Microcopy of the fibre bundles (retted) showed great fibre sensibility towards moisture, which could significantly influence mechanical properties. ii) Retting of green ribbons with microbial consortium. Interestingly, the extraction methods used in this study produced bast fibers with high cellulose content and low sugar and starch due to the removal of wax, oil, pectin and hemicelluloses. processes, namely, dew, water, enzymatic, mechanical, and chemical retting, mechanical and alkali methods There are two types of retting: stem and ribbon. The stalk stays submerged in water for 20 days. It seems that steaming in combination of compressing at high temperature would enhance the properties of OPTs. from the stem. 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 … Retting is a preferential rotting process to separate the fibre from woody stem without damaging the fibre cellulose. 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. The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. This was due to longer time of retting in the conventional retting process removed more pentosan. Corn leaves were collected after harvesting corn and the fibers were extracted by water retting. The retting experiment was carried out in artificial plastic retting tanks during 2009 and 2010. Synthetic hydrocarbon-based biostable polymeric fibres contribute about 60% of the global fibre production. 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. 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 - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Conventional retting process is not environmental friendly and requires large amount of water. Cultivation is dependent on the climate, season, and soil. ), A National Institute of Research on Jute and Allied Fibre Technology (ICAR) Special Publication, p. 62. The ribbons are coiled and then allowed for retting in water with or without using a microbial inoculum. In this review, author covered the basic information of PALF and compared the chemical, physical, and mechanical properties with other natural fibres. Calcium ions adsorb in a large quantity But … This article focusses on the microbial retting of jute bast fibres under aerobic condition using sequencing batch reactor. Merits of mechano-microbial retting 5.1.4. Bag Size: Height-37cm, Width-35cm, Gusset-18cm. ... For bacterial degumming, some researchers have studied the screening and community structure of degumming bacterial strains of jute (Banik et al. These observations are discussed in compari- son with similar observations made regarding other wilt diseases that we have studied. The fibers are first extracted by retting. are mostly recommended in the jute growing countries. However, the retting process may require less time if the quality of the jute is better. 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 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. The study shows that corn leaf fiber has good potential in technical textile applications. There are two types of retting: stem and ribbon. The retting time was optimized at 7 days. Among industrial fiber crops, jute is ranked second to cotton in terms of yield and planting area worldwide. Jahan et al. A publication of the Indian Jute Industries Research Associa-tion, Calcutta. There are two types of retting, stem and ribbon. Ribbon retting conducted in cement retting tank was faster than that in polythene tank. In this paper ,a plant is proposed to set up a sustainable and environment friendly jute extraction unit, integrated with updated technique and technology with a view to control raw jute fiber quality to support the fast moving industries and its benefits over the traditional method. Women and children usually do this Cole-Cole analysis was carried out to understand the phase behaviour of the composite samples. A total of 451 bacterial colonies have been isolated from five jute retting water samples in Bangladesh. The advantage of natural fibres is their continuous supply, easy and safe handling and biodegradable nature. We use cookies to help provide and enhance our service and tailor content and ads. Bamboo culms were processed using microorganisms, and fibre bundles were obtained. S. Banik et al. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. The most common conventional method is water retting but can also include pit soil, chemical, boiling, steaming and mechanical methods. This technique involves the application of microorganisms and/or enzymes. The fibers are first extracted by retting. • Conventional retting practice emits a little bit more nutrients, biogas and residues to the air and water 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. Great news!！！You’re in the right place for jute ribbon. Traditional processes are outdated which should be modified according to the technological advancement. Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality. 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. This fertile geographic region is shared by both Bangladesh and India (mainly West Bengal). 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. All rights reserved. Our results suggested that the bio-processing presented herein contributes to the possible development of a new means of bamboo bio-processing that can be regarded as a primary process to separate fibre bundles from non-cellulosic tissue in the culm. Jute fibre is the second most important fibre next to cotton. White pepper is the dried seeds obtained from pepper berries (Piper nigrum L.) after the removal of the pericarp. Retting and extraction processes have a profound effect on the quality of fiber and on the cost of fiber production. 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. All rights reserved. Bundling jute stems together and immersing them in slow running water consists of the retting process. The fibres are first extracted by retting. The fibers were subjected to alkali treatment in order to enhance the mechanical as well as handle properties. The new method of retting launched has been recognized as ribbon retting. The bacterial isolates are mostly Gram-positive rods of the genus Bacillus and fungi mainly of the genera Aspergillus and occasionally Penicillium. The jute is taken from the stem and the skin of the stem, which is called the ribbon. The optimum temperature is around 34°c, ditches, tanks, beels-haor or in vast. PEER-REVIEWED ARTICLE bioresources.com Tahir et al. developed jute retting techniques, covering jute ret with water hyacinth, ribboning and ribbon- retting technique (for water scarce areas) etc. 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. ... Ribbon retting reduces the requirement of water from 1:20 to 1:10 substrate liquor ratio, decreases the length of retting time and controls the level of environmental pollution to almost onefourth in comparison to that of whole plant retting. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography etc. A huge and inexpensive availability of oil palm trunk (OPT) can be a sustainable source of alternative wood for various structural applications, if it can be utilized. Abstract BBS.2008. The organisms could be adopted in industrial application for extraction of jute fibre. 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. Ribbon retting reduces time of normal retting by 4–5 days. These include the soil, retting, and jute genotype. The retting process consists of bundling jute stems together and immersing them in slow running 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.
