The advantage of natural fibres is their continuous supply, easy and safe handling and biodegradable nature. As the retting period increased the fineness of the fibre improved; however based on the tenacity (0.468 N/tex) and modulus (50.23 N/tex) a 25-day retting period was found to be optimum in this present study. ... 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). These observations are discussed in compari- son with similar observations made regarding other wilt diseases that we have studied. Although it is an integral part of the plant cell, presence of lignin considerably reduces the quality of the fiber of fiber-yielding plants. This may lead to the formation of several decomposition products like organic acids (acetic, lactic, galacturonic and butyric acid). The morphological characteristic were visualized based on the scanning electron microscope image. Cultivation is dependent on the climate, season, and soil. Usually mature stems of harvested jute plants are allowed to ret in pond or ditch water. in jute field covering the ditches with polythene sheets. processes, namely, dew, water, enzymatic, mechanical, and chemical retting, mechanical and alkali methods The ermicomposting process was complete within 45 days. This is followed by spraying with a fungal culture powder. 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. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. Christmas tree ribbon decorations are just the finishing touch to make your tree holiday-ready. 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 variation of papermaking properties of the produced pulp onretting process was insignificant. 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. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. Jute - an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. 5260 RETTING PROCESS OF SOME BAST PLANT FIBRES AND ITS EFFECT ON FIBRE QUALITY: A 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. Tables of content are generated automatically and are based on records of articles contained that are available in the TIB-Portal index. This also reduces environmental pollution to a great extent. Data about traditional jute retting process and ribbon retting process were collected through personal interview of jute growers. Here we report optimized microbial retting protocol that can lower retting period and produce high fibre quality. This technique involves the application of microorganisms and/or enzymes. 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. Different aspects of retting, right from quality and quantity of retting water, microorganisms with balanced pectinolytic and xylanase activities with minimal or low cellulase activities, largely determine fiber quality. 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. 17, No. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. Even though fibers were almost detached from the corn leaves in case of 20 days of retting, the fibers were found to be weak. Bangladesh: Ribon Retting of Jute and it’s importance. 3. June, 2015 Jute retting process: present practice and problemsin Bangladesh Vol. So there is a global need to search and explore new underexploited, but commercially important natural fibres. soil and water during retting. The optimum temperature is around 34°c, ditches, tanks, beels-haor or in vast. rice, wheat, maize, sunflower and mach more. 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. introduced ribbon retting in Bangladesh for jute-retting process. 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. 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. The retting process consists of bundling jute stems together and immersing them in low, running water. 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). This study concludes that comanagement can facilitate local capacity but in order to realize the full potential of this approach we must address the issues of inappropriate technologies for training, the financial barriers to fishers with low cash income, and uneven power relationships among stakeholders, to create an enabling environment for effective modern governance of the fisheries commons. Both methods require 14 to 28 days to degrade the pectic materials, hemicellulose, and lignin. or biologically (Rahman, 2010). India is the highest producer of Okra in the world, but after okra harvesting, the stem mostly remains underutilized. 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 low, running water. Jute retting process is one of the important responsible factors for quality of jute fiber. The structure of the homogalacturonic part of pectin forms The fibers are first extracted by retting. We use cookies to help provide and enhance our service and tailor content and ads. This treatment, Light and transmission electron microscope studies of naturally infected or inoculated staghorn sumac plants by Fusarium oxysporum f. sp. JUTE BAG 3 The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. would be the product of extraction of all possible agriculture based bio-waste, crop residues, stalks, straw etc of The most common conventional method is water retting but can also include pit soil, chemical, boiling, steaming and mechanical methods. Synthetic hydrocarbon-based biostable polymeric fibres contribute about 60% of the global fibre production. By now you already know that, whatever you are looking for, you’re sure to find it on AliExpress. The retting process consists of bundling jute stems together and immersing them in low, running water. Pulp yield of conventional retted jute fiber and jutestick was higher at any kappa number. 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. Direct penetration of host cell secondary walls by the pathogen occurred, but these were degraded to any extent only following intramural invasion. The retting process consists of bundling jute stems together and immersing them in low, running water. Jute Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. The fibers are first extracted by retting. This article is protected by copyright. After the particular thread for ribbon has been spun, dyed, and It is produced from plants in the genus Corchorus, family Tiliaceae. Therefore, Bangladesh Government has introduced ribbon retting method in different areas of the country to ease peeling of jute fiber. 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 residual gum content and weight‐loss ratio obtained from experimental results were consistent with those given by the model, and the average errors between them were 2.15% and 4.3%, respectively. Mucor has been found only in Bharat Jute Mill and Chaetomium is found only in Budge Budge Jute Mill fibre samples. 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. Improved method of upgrading barky jute at farmer's level with Penicillium corylophilum Dierckx. Jute is one of the bast fibers which has been proposed widely to accept and marketed as eco-friendly raw material for finished goods production, especially textiles. In: Mitra, B.C. This is called ribbon retting. The retted fibres were then degummed and bleached for better processibility and aesthetic look. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. 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. Jahan et al. In ribbon retting barks are removed from jute plants in the form of ribbon. This review highlights both conventional and latest biotechnological processes of white pepper production. Pineapple leaf fibre of certain varieties is widely used in Philippines for making apparels. Jute retting process is one of the important responsible factors for quality of jute fiber. 2003;Munshi and Chattoo 2008). There are two types of retting: stem and ribbon. Retting microbes consume the non-fibrous cementing materials mainly pectin and hemicellulose. 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. Jute is one of the important natural fibers after cotton in terms of cultivation and usage. is ideal. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.
