jute retting ppt

The … Get the plugin now Attempts were made to evaluate changes in the physicochemical parameters of water caused by jute retting, and their impact Retting If hemp or flax (linen) fibers are to be used in textiles and other high-quality applications, the bast fibers must be separated from the rest of the stalk. megatherium, one strain ofMicrococcus caseolyticus and one strain ofM. B. Kundu, S. Dey & B. L. Ghosh Indian Jute Industries' Research Association, 17 Taratola Road, Calcutta 700088, India (Received 3 May 1990; revised version received 7 September 1990; accepted 27 September 1990) ABSTRACT Commercial enzyme preparations, viz. Pectinolytic microorganisms are also responsible for retting, the central step in the textile production of vegetal fibres, such as flax, hemp, ramie and jute. The plate count of the water was 3.5 x 106 bacteria/ml, more than ten times that of normal pond Different kinds of jute products are made in Bangladesh and the products are environmentally friendly as well. Jute retting impacted lower native fish diversity indices like Shannon-Wiener index values (1.94 to 2.68) clearly indicated poor to moderate pollution status of the transitory water body in that area during monsoon in particular and throughout the year in general. National Institute of Research on Jute and Allied Fibre Technology, Kolkata has evolved a cost effective retting technique by which the quality of jute bre has been possible to be up-graded at least by one grade. Jute fibre is the second most important fibre next to cotton. This study aims at focusing the effect of jute water-retting process on aquatic lives and hence developing a pilot-scale treatment process. Retting is a process employing the action of micro-organisms and moisture on plants to dissolve or rot away much of the cellular tissues and pectins surrounding bast-fibre bundles, and so facilitating separation of the fibre from the stem. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. The water, penetrating to the central stalk portion, swells the inner cells, bursting the outermost layer, thus increasing absorption of both moisture and decay-producing bacteria. The pH of the water after repeated retting had dropped to 6.0, but the quality and colour of the fibres was unaffected. 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. Carrying Jute To Home Or Ponds For Processing Rarely Soaking Jute PPT. Retting, process employing the action of bacteria and moisture on plants to dissolve or rot away much of the cellular tissues and gummy substances surrounding bast-fibre bundles, thus facilitating separation of the fibre from the stem. It is used in the production of fibre from plant materials such as flax and hemp stalks and coir from coconut husks. This paper is the first published report that a strain of B. polymyxa is capable of retting jute… isolated fromretted jute are responsible for theprocess, as for instance, seven species of aerobic bacteria were isolated fromretted jute but only oneof them, B. poly-myxa, was capable of retting jute in laboratory tests. It’s easily and widely popularized due to property that it … While there are a few different botanical varieties of jute, one of the main species used to make jute fabric is Corchorus olitorius (white jute). Keywords: Jute retting, fibre, accelerated retting, quality fibre, microbial retting Jute, also known as Golden fiber, is an internationally traded major commodity originating primarily from two developing countries-Bangladesh and India. The jute is taken from the stem and the skin of the stem, which is called the ribbon. different types of retting processes used for bast plants such as hemp, jute, flax, and kenaf, with an emphasis on kenaf. Breakthrough in Jute Retting by ICAR – CRIJAF through Genome Sequencing of Microbes of Microbial Retting Consortium India is the largest producer of raw jute and jute goods in the world, contributing about 60% of the global production and providing livelihood support to about 5 million people in farming, trade and industry. International Biodeterioration 27 (1990) 223-235 Enzymatic Retting of Jute Ribbons S. Majumdar, A. These fibers are strong and can be made into long threads and hence are very durable in carrying the heavy weight easily. Bacteria capable of retting jute are present in pond water, in the soil of jute fields, and on the surface of jute plants. Jute retting process is one of the important responsible factors for quality of jute fiber. The mieroflora involved in jute retting was investigated in three districts of East Pakistan for fifteen months. Academia.edu is a platform for academics to share research papers. Jute: Retting Process Jute: Fibre Extraction Jute: Fibre washing and drying RAMIE FIBRE Ramie is one of the oldest fibre crops, having been used for at … 48.6%. It is highly used in making of the handicrafts and bags and clothes. In ribbon retting, ribbons are stripped out mechanically from the stem of mature jute plants, coiled and allowed to ret under water. luteus were isolated and their action on jute stems studied. PPT – Opportunities and Constraints in adopting Technologies for Improving Jute production PowerPoint presentation | free to download - id: 2a503-ZjAyY. Jute retting process is one of the important responsible factors for quality of jute fiber. The Adobe Flash plugin is needed to view this content. However, another species of jute, called Corchorus capsularis (tossa jute) is considered to be superior even though it is harder to cultivate. A total of 451 bacterial colonies have been isolate … Three strains ofBacillus macerans, four strains ofB. subtilis, three strains ofB. This technique has been found easier and cost effective for jute retting by the jute growers in India. 1. S ummary: A total of 1,438 colonies of aerobic and anaerobic bacteria has been isolated from samples of retted jute stems collected from 12 districts of East Pakistan. The defoliated jute bundles are then transported to the nearby retting facilities, immersed in clean or stagnant water according to the availability in natural retting tank, road-side ditches, sometimes in … Retting time must be carefully judged;… 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. Amongst the bast fibre crops, kenaf apparently has some advantages such as lower cost of production, higher fibre yields, and greater flexibility as … In Bangladesh, Jute is a vital sector from economical, agricultural, industrial, and commercial perspectives.
