Jute Jute Products Assignment. Anm Emtiaz. It is the cheapest vegetable fibre procured from the bast or skin of the plant's stem and the second most important vegetable fibre after cotton, in terms of usage, global consumption, production, and availability. It has high tensile strength, low extensibility, and ensures better breath ability of fabrics.
It is one of the most versatile natural fibres that have been used in raw materials for packaging, textiles, non-textile, construction, and agricultural sectors. It helps to make best quality industrial yarn, fabric, net, and sacks. Jute is second only to cotton in world's production of textile fibers. The first jute mill started production in Bengal in After more than years, the jute industry is now challenged by competition from alternative materials, by the recession in the international markets and by low awareness among consumers of the versatile, eco-friendly nature of jute fabric itself.
It is a golden bond with the Earth; its use is a statement about ecological awareness as it is a fully bio- degradable and eco-friendly fibre. It comes from the earth, it helps the earth and once its life is done it merges back into the earth. Physical Properties: Jute, as a natural fibre, has many inherent advantages like lusture, high tensile strength, low extensibility, moderate heat and fire resistance and long staple lengths. It is a biodegradable and eco-friendly.
It has much advantage over synthetics and protects the environment and maintains the ecological balance. The best quality fibres are pale white or silvery grey, common qualities are brownish and greenish are inferior, roots are usually darker without any luster. Better quality fibres shows matt and pitted surface with very poor strength.
Better quality fibres have fairly high luster but inferior quality fibres shows matt and pitted surface with very poor strength. It is attacked and damaged by the action of micro-biological agents like bacteria, fungus, moths, insects etc.
Yellowing of the fibre is observed due to the effect of sunlight. Advantages of Jute: Advantages of jute include good insulating and antistatic properties, as well as having low thermal conductivity and moderate moisture regain. Jute has the ability to be blended with other fibres, both synthetic and natural, and accepts cellulosic dye classes such as natural, basic, vat, sulfur, reactive, and pigment dyes. Cultivating Area and Producing Countries: Jute is a rain-fed crop.
India is one of the largest importers of Jute in South Asia and also produces processed jute products in the world, while Bangladesh is the largest producer and exporter of raw jute. India, Bangladesh, China and Thailand are the leading producers of Jute.
It is also produced in southwest Asia and Brazil. The jute fiber is also known as Pat, kosta, Nalita, Bimli or Mesta kenaf. It is cultivated in Indian subcontinent, Thailand, China and Africa. The two main types of jute, white jute Corchorus Capsularies and dark jute or tossa Corchorus Olitorius are grown in India, Bangladesh, Thailand, China, south Asian countries and Brazil. India is the largest producer of jute goods in the world, while Bangladesh is the largest cultivator of raw jute.
Nearly 50 percent of total raw jute production in India alone figures in West Bengal. End Uses of Jute and Jute Products: During the era of the great Mughal Emperor Akbar — states that the poor villagers of India used to wear clothes made of jute. History also states that Indians, especially Bengalis, used ropes and twines made of white jute from ancient times for household and other uses.
Chinese papermakers from very ancient times had selected almost all the kinds of plants as hemp, silk, jute, cotton etc.
Jute is not only a major textile fibre but also a raw material for nontraditional and value added non-textile products. Jute is used extensively in the manufacture of different types of traditional packaging fabrics, manufacturing Hessian, saking, carpet backing, mats, bags, tarpaulins, ropes and twines. The fibres are also woven into curtains, chair coverings, carpets, area rugs, hessian cloth, and backing for linoleum. Jute Diversification: Recently jute fibres are used in a wide range of diversified products: decorative fabrics, chic-saris, salwar kamizes, soft luggage's, footwear, greeting cards, molded door panels and other innumerable useful consumer products.
Supported by several technological developments today jute can be used to replace expensive fibres and scare forest materials. Very fine threads of jute can be separated out and made into imitation silk.
As jute fibres are also being used to make pulp and paper, and with increasing concern over forest destruction for the wood pulp used to make most paper, the importance of jute for this purpose may increase. Jute has entered various diversified sectors, where natural fibres are gradually becoming better substitution. Among these industries are paper, celluloid products films , non-woven textiles, composites pseudo-wood , and geotextiles.
Diversified jute products are becoming more and more valuable to the consumer today. Among these are espadrilles, floor coverings, home textiles, high performance technical textiles, Geotextiles, composites, and more.
Diversified byproducts which can be cultivated from jute include uses in cosmetics, medicine, paints, and other products. Geotextiles: Geotextiles is more popular in the agricultural sector. It is a lightly woven fabric made from natural fibres that is used for soil erosion control, seed protection, weed control, and many other agricultural and landscaping uses.
The Geotextiles can be used more than a year and the bio-degradable jute Geotextiles left to rot on the ground keeps the ground cool and is able to make the land more fertile. In s and s, major share of national income and manufacturing employment was largely contributed by Jute sector. But the demand had to be filled. As the use of polythene and other synthetic materials as a substitute for jute increasingly captured the market, the jute industry in general experienced a decline.
During some years in the s, farmers in Bangladesh burnt their jute crops when an adequate price could not be obtained. Many jute exporters diversified away from jute to other commodities.
Jute-related organizations and government bodies were also forced to close, change or downsize. The long decline in demand forced the largest jute mill in the world Adamjee Jute Mills to close in Bangladesh. In the year , this sector accounted for a more 3. Farmers in Bangladesh have not completely ceased growing jute, however, mainly due to demand in the internal market. Jute has entered many diverse sectors of industry, where natural fibres are gradually becoming better substitutes.
Many small entrepreneurs are now getting interest in jute and jute products. They are engaging themselves in the production of many diversified products. Growing international interest for diversified and lifestyle jute products have prompted Bangladeshi jute manufacturers and exporters to develop value-added jute products like jute gunny bag or sack bags, jute yarn and twine, handicrafts, shopping bags, beach bags, sports and travel bags, wine bags and other jute textiles.
Jute is one of the most valuable natural resources of Bangladesh and is truly ruled the world market. Bangladeshi Jute bags are available in neutral and earthy colors like olive green and different shades of white. These quality jute bags made their way into almost every nature lovers home. Export Performance of Jute: Please see the below figures, here are data of jute and jute products export share percentage for last four decades of Bangladesh.
This had come down to 23 per cent by FY, whilst in FY the share came down to 4. It is notable; however, that share began to rise over the next year to reach 4. Total export of raw jute and jute goods did not increase significantly; it rose from USD It is important to mention here that, raw jute and jute goods export increased significantly and almost doubled in FY compared to FY by about In FY, Bangladesh exported 4, thousand bells of raw jute and thousand tonnes of jute goods.
Major jute items that were exported included — raw jute, jute yarn and twine jute carpet, jute ropes, and other jute items. Prospect of Jute in Bangladesh: A ban on the use of plastic bags in different countries -- from the US to Europe, Africa, Asia and Australia -- has opened new opportunities to export diversified jute products.
The US, Europe and China would be the biggest markets for shopping bags, once the ban on the use of plastic bags would fully come into force in a few years. India exported more than 70 million jute shopping bags in , against around 1 million by Bangladesh. Moreover, Jute sticks are very useful material for various purposes as fencing and roofing materials for making sheds.
These are also used as important industrial raw material for making particle board whose demand is increasing in national and international Market. Moreover, the quality of the raw material is the best available in the world. Bangladesh is the natural abode of jute cultivation on account of its climatic situation and soil condition. Bangladesh is recognized as one of the major jute producing countries. In addition, Jute and Jute products are renewable, biodegradable, eco-friendly, easily disposable and natural commodity.
The activities pertaining to the traditional jute industries do not require much skilled labour. Again, the skill that is required can be improved through simple training on the job itself. There are educated and professionally experienced people in the country to run industries including jute industries.
New technologies for production of diversified jute products are now available. Bangladesh is in jute business for decades. There are adequate arrangements for facilitation of jute trade inside and outside the country. An elaborate system exists for procurement and disposal of raw jute. Some jute products are naturally fire resistant.
Constraints-Delaying the Take-off of this sector: The cost of producing quality yarn is 40 percent higher in Bangladesh than India because of technological disadvantages. India has set up composite jute mills with modern machinery and technologies to make fabric, dyeing or lamination under one roof, he said.
Bangladesh has nearly jute mills, but none with dyeing and lamination facilities, which are essential to producing diversified products. To meet the demand farmers motivate to take up high earning agricultural activities resulting in decreased Jute production.
Water is necessary for Jute retting. Scarcity of water will threat jute retting in future resulting motivates farmers to take up other agricultural activities. Indian, Chinese and Vietnamese jute diversified goods are more popular because of their product range and depth, colours, designs and quality.
Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about B. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth.
Textile manufacturing by pre-industrial methods
Fibers derived from bio-based sources such as vegetables and animal origin are termed as natural fibers. This definition includes all natural cellulosic fibers cotton, jute, sisal, coir, flax, hemp, abaca, ramie, etc. There are also man-made cellulose fibers e. Natural fibers being cost effective and abundantly available yields high potential in various industrial and commercial applications such as in the interior applications of the passenger cars, panels for partition and false ceiling, partition boards, roof tiles, coir fibers in packaging, furniture applications, as insulating materials in low energy houses, geo-textiles for soil protection and erosion control, enhancing barrier properties, composites etc.
Natural Fibers: Applications
They do not damage the ecosystem, they can grow in different climatic zones and they recycle the carbon dioxide for the atmosphere. These plants can contribute to a better agricultural balance in Europe and they will contribute to the growing demand from an expanding population for cellulosic pulp in the next millennium. Some of these green plants like flax and hemp can be used for cleaning soil, polluted by heavy metals, by extracting and removing cadmium, lead, copper and others. The estimated world-wide production of fibrous raw materials from agricultural crops is provided in Table 1. Other possible sources of straw, which could be used as raw materials for applications such as composites and as energy crops are given in Table 2. Table 1: Estimated global tonnage of fibrous raw materials from agricultural crops Crop Plant component Availability ' tonnes Cereals straw: barley straw There are two parallel textile fibre technologies: 2. Though difficult in handling, traditional long flax, ramie and hemp are still produced and processed by slightly modernised methods. These products include: percent linen or ramie knitted apparels.

The sub-title of this little volume indicates that practically all the processes involved in the cultivation of jute plants, the extraction of the fibre, and the transformation of the fibre into useful commodities, have been considered. In addition, every important branch of this wide industry is liberally illustrated, and the description, although not severely technical, is sufficiently so to enable students, or those with no previous knowledge of the subject, to follow the operations intelligently, and to become more or less acquainted with the general routine of jute manufacture. As a matter of fact, the work forms a medium of study for textile students, and a suitable introduction to the more detailed literature by the authors on these textile subjects. Advertisement: J.

Bast fibers are the fibrous part of the plant just below the bark. They are a family of fibers that allow for the entire plant to be used. These fibers are annually renewable crops that come off of the stalks rather than the leaves and grow in 90 to days. These low maintenance, high-quality fibers do not require chemicals or pesticides, they put nutrients back into the earth similar to nitrates, take up less space and water, and erosion is nonexistent. For these reasons, bast fibers are quickly becoming the millennial alternative for environmental responsibility. Jute is extracted from the bark of the white jute plant and tossa jute. Jute is a rain-fed crop with almost no need for fertilizer or pesticides, making it environmentally friendly. These fibers are primarily composed of the plant materials cellulose, which is a major component of the plant fiber, and lignin, which are major components of the wood fiber. Jute, being one of the most affordable fibers, has a number of benefits associated with it.
THE JUTE INDUSTRY
Услышав слова: "Слуги Учителя приветствуют. Мы ждали вашего прихода", Элвин понял, что барьеры рухнули. И в тот же миг Шалмирана и необычайные пришельцы исчезли, и он вновь стоял в глубинах Диаспара перед Центральным Компьютером.
Через короткое время Олвину и Хилвару станет известно, не проделали ли они его впустую. Планета, к которой они приближались, находилась теперь от них всего в нескольких миллионах миль -- красивый шар, испещренный многоцветными пятнами света. На ее поверхности нигде не могло быть темноты, потому что, по мере того как планета поворачивалась под Центральным Солнцем, по ее небу чередой проходили все другие светила системы.
Сумеют ли они вернуться к самому основанию города и проникнуть сквозь занавес отделяющий непреложно известную историю от мифов и легенд Начала?. Они погрузились в прошлое уже на пятьсот миллионов лет. За пределами стен Диаспара, неизвестная мониторам, лежала совсем иная Земля.
То было что-то слишком огромное и слишком уж далекое по времени для понимания, а вот всхлипывания ребенка пронзали сердце насквозь. В Диаспаре Олвин познал, что такое любовь, но теперь перед ним было что-то равно драгоценное, что-то такое, без чего сама любовь никогда бы не могла достигнуть полного своего расцвета, навечно оставаясь ущербной.
