Moreover, the fibre filaments were stronger, improved coloured and finer textured compared to conventional stem retted jute fibres. This study provides empirical evidence that co-management programs have applied a number of strategies (e.g. is ideal. 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. S. Banik et al. ABSTRACT The jute industry is facing severe competition from synthetic packaging materials in the present situation. 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. 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. 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. Usually mature stems of harvested jute plants are … Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances.

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. Retting may be defined as the separation of bast fibres from the core tissues of the stem. In: Mitra, B.C. They were air dried … 12, Regent Park, Kolkata-700040, India. Cultivation is dependent on the climate, season, and soil. Even though fibers were almost detached from the corn leaves in case of 20 days of retting, the fibers were found to be weak. India is the highest producer of Okra in the world, but after okra harvesting, the stem mostly remains underutilized. A neural network model was established based on the experimental results, and the optimal processing parameters of degumming were determined finally with genetic algorithm through a fuzzy relationship between the processing parameters and degumming effects. From the socio-economic prospective, PALF can be a new source of raw material to the industries and can be potential replacement of the expensive and non-renewable synthetic fibre. The ribbon retted jute fibres are absolutely free from bark and were of higher grade. The change in chemical composition due to alkali treatment was determined using Fourier transmission infrared spectroscopy and chemical composition analysis. Over retting causes degradation of fibre cellulose while under retting causes incomplete removal of gummy materials viz., pectic substances. 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. Copyright © 2021 Elsevier B.V. or its licensors or contributors. As jute made products are getting popular worldwide, steps are to be taken to comply with the demand of customers and conservationists. The ribbons are coiled and then allowed for retting in water. Pronounced alterations of pit membranes of bordered pits occurred, with their outer portions disrupted into bodies of opaque matter, strongly labelled for cellulose, and their middle portions as unlabelled shreds. Although natural fibres exhibit admirable physical and mechanical properties, it varies with the plant source, species, geography etc. 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. The jute fiber comes from the stem and ribbon (outer skin) of the jute plant. Jute—an important cash crop of eastern India is traditionally grown for extraction of fibre by a natural microbial process known as retting. Haque et al. 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 well-explored natural fibres have limited availability in terms of quantity and those cannot fulfil the total requirement of fiber applications. The farmers are involved in jute … has apparent advantages over the retting processes by having significantly shorter retting time and acceptable 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. Though ribbon retting is more advantageous over the traditional method in terms of retting duration, water content and environmental pollution, ... Quality of fiber depends on nature of retting. Most of the defects arising from conventional retting could be overcome by ribbon retting. Addition of efficient pectinolytic microbial inoculum may further boost up or improve the ribbon retting process. A slight increase in fiber density was observed for NaOH and benzoate retted bast fibers indicating cell wall densification. • Raw jute bales from jute fields or suppliers, carried by trucks are unloaded are stacked in the jute mills godown. Synthetic hydrocarbon-based biostable polymeric fibres contribute about 60% of the global fibre production. would be the product of extraction of all possible agriculture based bio-waste, crop residues, stalks, straw etc of 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 … The retting process consists of bundling jute stems together and immersing them in low, running water. But use of efficient pectinolytic microbial inoculum improves quality of fibre, further reduce the time of retting and the environmental pollution. solution. There are two types of retting: stem and ribbon. 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. Whole sterns were retted for 14 days and ribbons for 9 days. 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. In: Proceedings of International Seminar on Jute and Allied Fibres */Changing Global Scenario. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. After the retting process… 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.
