What is Jute Fabric: Properties, How its Made and Where
The Plant Jute is extracted from the bark of the white jute plant Corchorus capsularis and to a lesser extent from tossa jute C. It is a natural fibre with golden and silky shine and hence called the Golden Fibre. Jute is a rain-fed crop with little need for fertilizer or pesticides. Yields are about 2 tonnes of dry jute fibre per hectare. Jute is one of the most affordable natural fibres and considered second only to cotton in amount produced and variety of uses of vegetable fibres.
The fibre Jute is long, soft and shiny, with a length of 1 to 4 m and a diameter of from 17 to 20 microns. Jute fibres are composed primarily of the plant materials cellulose major component of plant fibre and lignin major components of wood fibre. The fibres can be extracted by either biological or chemical retting processes. Given the expense of using chemicals to strip the fibre from the stem biological processes are more widely practices.
After the retting process, stripping begins. In the stripping process, non-fibrous matter is scraped off, leaving the fibres to be pulled out from within the stem. A hectare of jute plants consumes about 15 tonnes of carbon dioxide and releases 11 tonnes of oxygen. Cultivating jute in crop rotations enriches the fertility of the soil for the next crop. Jute also does not generate toxic gases when burnt. Uses of Jute Jute is a versatile fibre.
During the Industrial Revolution, jute yarn largely replaced flax and hemp fibres in sackcloth. Today, sacking still makes up the bulk of manufactured jute products. A key feature of jute is its ability to be used either independently or blended with a range of other fibres and materials. While jute is being replaced by synthetic materials in many of these uses, some take advantage of jute's biodegradable nature, where synthetics would be unsuitable. Examples of such uses include containers for planting young trees, geotextiles for soil and erosion control where application is designed to break down after sometime and no removal required.
Advantages of jute include good insulating and antistatic properties, as well as having low thermal conductivity and moderate moisture retention. Textiles The major manufactured products from jute fibre are: Yarn and twine, sacking, hessian, carpet backing cloth and as well as for other textile blends. It has high tensile strength, low extensibility, and ensures better breathability of fabrics.
The fibres are woven into curtains, chair coverings, carpets and area rugs and are also often blended with other fibres, both synthetic and natural. The finest threads can be separated out and made into imitation silk. Jute can also be blended with wool. By treating jute with caustic soda, crimp, softness, pliability, and appearance is improved, aiding in its ability to be spun with wool. Packaging Jute is extensively used for sacking for agriculture goods as well as being used increasingly in rigid packaging and reinforced plastic and is replacing wood in pulp and paper.
By-products Diversified by-products from jute include its use in cosmetics, medicine, paints, and other products. Jute sticks are used as fuelling and fencing materials in the rural areas of jute producing countries. These are good substitute for forest wood and bamboo for production of particle boards, pulp and paper. Nepal and Myanmar also produce a small amount of jute.
Pakistan, although it does not produce much, imports a substantial amount of raw jute, mainly from Bangladesh, for processing. Production and trade Jute production fluctuates, influenced by weather conditions and prices. Annual output in the last decade ranges from 2. India exports nearly tonnes of jute products, the remainder being consumed domestically. Market Outlook As the demand for natural fibre blends increases, the demand for jute and other natural fibres that can be blended with cotton is expected to increase.
Although currently diversified jute products account for a small percentage of total consumption this segment could expand rapidly with further investment in resources and expertise.
In terms of conservation agriculture, jute also has a set role and is now accepted as an environmental, cost effective material for various soil applications. Jute Developments Several projects are being carried out in Bangladesh by the Common Fund for Commodities CFC to improve the capacity of jute producers and support industry diversification. Jute Reinforced Polyolefines for Industrial Applications, Phase II: Material Optimization and Process Up-Scaling for Commercialization T he project aims at developing and industrially testing jute fibre reinforced thermoplastic composites for various uses to replace glass fibre and other products.
Materials optimization and process up-scaling is expected to promote investment and greater use of jute fibre in various industries thereby opening up new market niches for jute fibre. Entrepreneurship Development in Diversified Jute Products The project involves poor women and other rural and urban unemployed and underemployed: hence significant alleviation of poverty is expected from the project.
The project pilots the application of new physico-chemical treatments for jute dyeing, bleaching and proofing, and the integrated production of value-added jute blended products through small-scale spinning and weaving employing small-scale hand looms and power looms and the manufacturing of home textiles.
Model chemical treatment plants in India and Bangladesh are used to demonstrate the treatment of chemical effluent to minimize the polluting effects of dyes and other chemical applications. Other projects have been commissioned to examine the markets for geo-textile applications and projects to improve efficiency of production for various jute uses.
Together these projects build capacity in jute processing and help position the fibre more strongly on international markets and increase awareness of the fibres potential. FAO Home. Economic and Social Development Department. Future Fibres.

Jute fabric is a type of textile fiber made from the jute plant. 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. However, another species of jute, called Corchorus capsularis tossa jute is considered to be superior even though it is harder to cultivate. Cotton takes the title of most-produced plant-based fiber, but jute is a close second. Jute plants grow to be over 10 feet high, and the fibers derived from these plants are harvested in a single long string.

Yarn is a long continuous length of interlocked fibres , suitable for use in the production of textiles , sewing , crocheting , knitting , weaving , embroidery , or ropemaking. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Yarn can be made from a number of natural or synthetic fibers. Many types of yarn are made differently though.
Mechanical processing using enzymes, which are eco-friendly in nature, would be an alternative to the chemical processing of regenerated bamboo fiber production. For information on health risks see The use of chemicals in processing, such as in the Lyocell process, are factors which can lead to side reactions and the introduction of hazardous chemicals into the environment. Processing is time consuming. This review discusses cotton textile processing and methods of treating effluent in the textile industry.

We have been manufacturing fibers from the renewable raw material wood for about 80 years. We have also secured a leadership position in the 21st century thanks to a passion for our products and technological know-how. We have adapted it to the ecological demands of the 21st century by achieving high recovery rates for chemicals. On the other hand, we implement the most advanced closed-loop lyocell production process. The pulp has to be converted and matured, then further complicated chemical processing steps follow. Finally a honey-like mass is formed which is pressed through micro-fine nozzles and the fibers are spun.

Yarn consists of several strands of material twisted together. Each strand is, in turn, made of fibers, all shorter than the piece of yarn that they form. These short fibers are spun into longer filaments to make the yarn. Long continuous strands may only require additional twisting to make them into yarns.

Bulky is a term used to describe yarns which are of large cross-section in relation to their weight per unit length. Yarns of wool are bulky generally speaking because wool fibers are not essentially straight, but have a natural crimp or curl. Thus, Wool yarns do not consist of essentially linear parallelized fibers but the natural curl in the wool fibers causes wool yarns to be of lower density and higher covering power than would be the case if the fibers were essentially linear and parallelized.

Synthetic fibers of acrylonitrile polymers are widely used because they embody a number of outstanding properties, one of the more important of which is their wool-like character. Various methods of producing yarn have been adopted with a view to providing textile articles of these fibres with the bulk and feel of wool. For example, if shrinkable and fully shrunk staple fibres are spun together and the yarn is subjected to a shrinkage-initiating treatment by dyeing or steaming, the yarn "bulks up" through shrinkage of the shrinkable staple fibre and acquires a bulky, wool-like feel. Another commercially important possibility is the breaking conversion by breaking of tows, in which a tow is broken into slivers of shrinkable fibres which, if desired, may be converted into non-shrinkable fibres by steaming. Under these circumstances, any processor is able to produce his own bulk yarn by suitably selecting the degree of shrinkage and the proportion of shrinkable fibres in the mixture as a whole.
