This indicates that the piling microbes might play a significant role in remoling residual pectin from the fibre during piling of jute. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. Retting and extraction of jute problems and prospects. Increasing global demand of the spice outpaced the supply as the conventional production method used is laborious, lengthy and also less hygienic. Paul, N.B., Bhattacharyya, S.K., 1978. 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. This treatment, Light and transmission electron microscope studies of naturally infected or inoculated staghorn sumac plants by Fusarium oxysporum f. sp. June, 2015 Jute retting process: present practice and problemsin Bangladesh Vol. The retting process is done either with the help of chemicals (N 2 H 8 C 2 O 4 , Na 2 SO 3 , etc.) Pectobacterium sp. The bleachability of jute fiber pulp was better than that of jute stick pulp.Conventional retted fibers showed slightly better bleachability. Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances. In: Mitra, B.C. After the retting process, stripping begins ; women and children usually do this job. 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. These elements were sometimes observed to be confluent with fungal cells and to label for chitin. Pulp yield of conventional retted jute fiber and jutestick was higher at any kappa number. The retting process consists of bundling jute stems together and immersing them in slow running water. is ideal. Review paper also reveals about properties of fiber extracted from Indian Agriculturist 31 (I), 49 Á/52, Paul, N.B., Basak, M.K., 1987. Ribbon retting reduces time of normal retting by 4–5 days. Calcium ions adsorb in a large quantity Jute fibre is the second most important fibre next to cotton. The retting process consists of bundling jute stems together and immersing them in low, running water. White pepper is the dried seeds obtained from pepper berries (Piper nigrum L.) after the removal of the pericarp. This paper reviews different types of retting processes used for bast plants such as hemp, jute, flax, and kenaf, with an emphasis on kenaf. Conventional retting process is not environmental friendly and requires large amount of water. Microbial inoculation produced remarkable improvement in jute fibre strength (26.62–28.91 g/tex) and fineness (2.76–2.92 tex) over control. There are two types of retting, stem and ribbon. A detailed study of chemical, physical and mechanical properties will bring out a logical and reasonable utilization of PALF for various applications. Present study deals about dynamic mechanical, thermal analysis and flammability of treated and untreated pineapple leaf fibre (PALF) and kenaf fibre (KF) phenolic composites. Traditional processes are outdated which should be modified according to the technological advancement. 2007;Das et al. In this technique OPT samples were steamed at temperature 130 °C for 2 h before being compressed at high temperature. Improved retting technology for quality jute fiber production has been introduced where ribbon retting is done instead of stem retting and retting is done with a very small volume of water [16]. Ribbon retting reduces time of normal retting by 4–5 days. They're also a Christmas craft that is simple to make, and the style options are endless.. First, choose a good-quality ribbon. 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. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Retting is a microbiological process and, therefore, the end-point is determined by inspecting a few plants each day from the tenth day onward. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. The traditional methods for separating the long bast fibres are by dew and water retting. Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality. quality fibres, but it is quite expensive. Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. After the retting process, stripping begins. Most of the defects arising from conventional retting could be overcome by ribbon retting. ABSTRACT The jute industry is facing severe competition from synthetic packaging materials in the present situation. 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. Jute - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Basic methods include dew retting and water retting. There are two types of retting: stem and ribbon. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. Cultivation is dependent on the climate, season, and soil. Synthetic hydrocarbon-based biostable polymeric fibres contribute about 60% of the global fibre production. Water retting is a century old but the most popular process in extracting fine fibres. The retting process consists of bundling jute stems together and immersing them in low, running water. The hemp fibres contain 56.1wt.% of cellulose, 20.1wt.% of pectin, 10.9wt.% of hemicellulose and 6wt.% of lignin. solution. Pineapple leaf fibre of certain varieties is widely used in Philippines for making apparels. 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. Even though fibers were almost detached from the corn leaves in case of 20 days of retting, the fibers were found to be weak. In ribbon retting barks are removed from jute and kenaf plants mechanically or manually in the form of ribbon. Bundling jute stems together and immersing them in slow running water consists of the retting process. fibre quality through retting. Most of the defects arising from conventional retting could be overcome by ribbon retting. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. Diverse extrinsic material (including latex in some instances) or elements occurred in vessel lumina. Different factors that influence the production of quality jute fibers are presented. The retting of jute and mesta */a review. After the retting process… Moreover the wash water arising due to rinsing of retted fibre was recycled, thereby achieving a zero discharge concept. 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. Samples were exposed to outdoor conditions to evaluate their resistance against biological deterioration. The fibers are first extracted by retting. 17, No. The retting process consists of bundling jute stems together and immersing them in … Modle No: 786-06 Fabric: Natural laminated 13*13 jute. Cole-Cole analysis was carried out to understand the phase behaviour of the composite samples. processes, namely, dew, water, enzymatic, mechanical, and chemical retting, mechanical and alkali methods After the retting process, stripping begins. 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. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features ... One percent alkali solubilities of jute fiber and jute stick in both retting processes were almost similar (31% for jute stick and 21% for jute fiber). Mechano-microbial Retting Mechano-microbial retting of jute involves two distinct operations viz. In contrast with the ribbon retting of jute (Banik et al. So there is a global need to search and explore new underexploited, but commercially important natural fibres. Retting is the main challenge faced during the processing of bast plants for the production of long fibre. To read the full-text of this research, you can request a copy directly from the authors. The Tan delta peak height was low for pure phenolic and maximum for 60% PALF phenolic composites. 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. Moreover, requirement of water for ribbon retting is almost half in comparison to conventional whole plant retting under normal condition. Jute is a rain-fed crop with little need for fertilizer and pesticides. 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. Retting operation was carried out for varying time period namely 10, 15, 20, 25, 30 and 35 days respectively. An increase in cellulose and hemicelluloses content was detected along with a decrease in lignin content after bio-processing. The microorganisms in dif-ferent combinations of consortia showed synergistic effect resulting in increased PG (35.52–46.61 IU/g cell wet weight), PNL (39.79–72.12 U/ml), xylanase (0.705–0.840 mol/ml/min) and little cellulase (0–0.153 mol/ml/min) activities. The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. Among the two transgenic plant types one exhibited an increase in cellulose content and concomitant improvement of glucose release. The retted fibres were then degummed and bleached for better processibility and aesthetic look. Chemical composition analysis of the fibre bundles obtained showed that the components are mainly cellulose, hemicelluloses and lignin. In: Proceedings of International Seminar on Jute and Allied Fibres */Changing Global Scenario. Scarcity of jute retting water in some areas of Bangladesh is one of the major issues. Enzymatic retting has apparent advantages over other retting processes by having significantly shorter retting time and acceptable quality fibres, but it is quite expensive. Fungal isolates are mainly of the genera Aspergillus and, to a lesser extent, of the genus Penicillium and Dendrophoma. After the particular thread for ribbon has been spun, dyed, and Improved method of upgrading barky jute at farmer's level with Penicillium corylophilum Dierckx. In conventional retting, a huge biomass undergoes decomposition in stagnant water, so retting causes environmental pollution. Retting is a preferential rotting process to separate the fibre from woody stem without damaging the fibre cellulose. Quantitative as well as qualitative evaluation of microorganisms associated with piling of jute has been studied using raw jute fibre, jute fibre from laboratory bins and fibre samples collected from two jute mills (M/s Bharat Jute Mill and M/s Budge Budge Jute Mill). You can request the full-text of this article directly from the authors on ResearchGate. After harvesting the vegetable crop, i.e., Lady Finger, the effort was made to use the leftover plant biomass to extract fiber, following a similar process of bast fiber extraction. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. A slight increase in fiber density was observed for NaOH and benzoate retted bast fibers indicating cell wall densification. The fibers are first extracted by retting. This crop residue are one of the biggest component of all agriculture bio waste which either left in field or its large amount, 140 million tones is burnt on the field primarily to clear the remaining straw and stubble after the harvest. / 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. in jute field covering the ditches with polythene sheets. After the retting process, stripping begins; women and children usually do Retting Environment • Jute assimilates about 5.8 ton CO2 from the atmosphere in its lifetime (Rahman and Bala, 2009). Jute is one of the important natural fibers after cotton in terms of cultivation and usage. ultimately or left in the field unutilized. Higher pectinolytic bacterial isolates were predominant in the later stage of jute retting. PEER-REVIEWED ARTICLE bioresources.com Tahir et al. The ditches may be filled with clear water from tube well or from any other water sources. Environmental Scanning Electronic Microcopy of the fibre bundles (retted) showed great fibre sensibility towards moisture, which could significantly influence mechanical properties. The most common conventional method is water retting but can also include pit soil, chemical, boiling, steaming and mechanical methods. In contrast with the ribbon retting of jute (Banik et al. 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 fibres produced from kenaf using chemical retting processes are much cleaner but low in tensile strength. It has been widely used as seasoning and condiments in food preparation. 16 s ribosomal gene sequencing analysis identified 2 phyla- Firmicutis (80.55%) and Proteobacteria (19.45%). The study shows that corn leaf fiber has good potential in technical textile applications. Some of this material labelled for pectin, often in association with tyloses, as did other opaque matter in paratracheal, Access scientific knowledge from anywhere. has apparent advantages over the retting processes by having significantly shorter retting time and acceptable The pH of the post-retting water samples became acidic, and the electrical conductivity (Ec), chemical oxygen demand (COD) and hardness increased. / Industrial Crops and Products 17 (2003) 183 Á/190 References Alam, A., 1998. This work shows that optimized degumming processes could be achieved using this model by avoiding time‐consuming and costly trial‐and‐error tests. Peak of loss modulus of pure phenolic showed very less, after the addition of kenaf/PALF peaks were higher and shifted towards high temperature. 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). This review highlights both conventional and latest biotechnological processes of white pepper production. For minimizing the problems of jute retting process, the farmers are now more interested on ribbon retting process. longans showed higher fruit disease index, lower content of pericarp cell wall materials (CWMs), as well as lower contents of pericarp cell wall components (chelate-soluble pectin (CSP), sodium carbonate-soluble pectin, hemicelluloses, and cellulose), but higher content of pericarp water-soluble pectin (WSP). The retting time was optimized at 7 days. • Conventional retting practice emits a little bit more nutrients, biogas and residues to the air and water Effectof ribbon retting on kraft pulping was also studied. water are also used for retting. Corn leaves were collected after harvesting corn and the fibers were extracted by water retting. 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. This also reduces environmental pollution to a great extent. 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 presented alkaline status while ORP was negative namely under anaerobic status. 5 Proofreading When you feel confident about your revisions, move on to the last writing process step: proofreading. Mostly, raw materials are being sourced carefully in terms of its decomposition after use but its cultivation and processing stages should be controlled as a manner to ensure that environment is being taken care of. Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Throughout training sessions there were instances where technology was introduced without attention to its usefulness for farmers and fisher groups.
