It is related to flax and hemp and can be used to produce a fine linen-like cloth. www.tlist-journal.org Textiles and Light Industrial Science and Technology (TLIST) Volume 2 Issue 4, October 2013 Study on Extraction of Bamboo Fibres from Raw Bamboo Fibres Bundles Using Different Retting Techniques Varinder Kaur1, D P Chattopadhyay2, Satindar Kaur3 1Department of Applied Chemical Sciences & Technology, Guru Nanak Dev University, Amritsar 2Department of Textile … A huge benefit of using bamboo as the organic base for textile fibres is that there is no need for pesticides or fertilisers when growing bamboo. Natural retting is considered to be impractical for modern industrial purposes, but this low technology will always be appropriate somewhere, and never completely obsolete. Jute is a long, soft, shiny vegetable fibre that can be spun into strong threads. Naturally Advanced Technologies Inc. (NAT), Vancouver, Canada, has granted licence to Tuscarora Yarns Inc. under which Tuscarora will design and manufacture specialty yarns containing blends of NAT's CRAILAR� Flax fibre with cotton or other fibres. NAT expects the partnership will open avenues for the fiber's use in underexplored clothing markets such as couture fashion, sports performance and extreme weather gear. The common stinging nettle has great potential for fibre crop production; it is far stronger than cotton and finer than other bast fibres. 2013). Hemp is an ecologically and sustainably important plant, running in tandem with ‘green future’ objectives and is often referred to as the World’s most useful plant. Along with flax, this fast-growing plant is now the basis for a new textile woven on conventional cotton-machinery, called CRAILAR� Organic Fibres. Chemical retting is more expensive and does not produce the superior quality fibre obtained from the biological retting process. Very little bamboo is irrigated and there is sound evidence that the water-use efficiency of bamboo is twice that of other trees. Kenaf has a long history of cultivation dating back over 4000 years in parts of Africa it was also cultivated in India and Thailand. In Bangladesh it was called the “golden fibre,” as trade in jute brought the largest amount of foreign currency into the country. Flax is the only commercial cellulosic textile plant indigenous to Western Europe; it is also the strongest of all the vegetable fibres being two to three times stronger than cotton. Example:Jute is associated with the process of Retting. It is high in both tensile and ductile strength. ting. A new process has recently been developed that makes it possible to use the same machinery as cotton when weaving hemp. Linen refers to yarn and fabric made from the fibres of the stem of the flax plant.

With crop rotation it is not necessary to use chemical fertilisers and pesticides when growing flax. 3.1 ~ Retting Hemp bast fiber must be separated from the woody core by mechanical means (decortication) or by the process of "retting" (rotting). Chemical retting involves immersion of the dried plants in a tank with a solution of chemicals, such as sodium hydroxide, sodium carbonate, high pH agents, pectinolytic enzymes or mineral acids. The production is concentrated in Bangladesh and some in India, mainly Bengal. The bast fibres are stuck together with a ‘glue’ formed of pectins and lignins. It is commonly used in regions of low water supply. Dew retting is a more sustainable process where the stalks are left out in the field for 6 weeks, and are acted upon by the dew, sun and fungi. Retting is a controlled ‘rotting’ to remove the gummy (pectinous) substances which glue the bast fibres together, and this can be achieved with different methods: Water retting involves leaving the stalks in tanks or ponds of water (or in a running river), and are acted upon by bacteria, rotting the stalk which separates the fibres from the woody core. Plantation-grown kenaf is capable of growing from seedlings to 5 m at maturity in five months. Linen, or flax is the most luxurious of all the bast fibres and has a very specific tactile appeal; it is smooth and lustrous to both the eye and hand, the fibre is almost silky in texture, yet embodies a springy freshness. Bamboo is also extremely efficient at minimising CO2 and generates up to 35% more oxygen than equivalent stands of trees. Even when these are used flax requires only one fifth of the pesticides and artificial fertilisers that is required for commercially grown cotton. The world’s premier institute for the development of hemp is still situated in The Ukraine where it develops new varieties with improved fibre content, increased yield and low THC. Bacteria are economically important as these microorganisms are used by humans for many purposes. Dutch company Brennels, in consultation with the De Montfort STING project is currently cultivating nettles in Holland's North-East Polder region. Not all bacteria 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- … The penetration of water into the stems causes the detachment of the bast fibres, thus allowing the entry of retting bacteria, which demolish the fibre‐binding pectins (Donaghy et al. The process involving the recognition of phage to bacterium is called landing. In addition it controls topsoil erosion and produces great amounts of oxygen. 1) Meaning of retting = 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. The most widely practiced method of retting, water retting, is performed by submerging bundles of stalks in water. The extensive root system of bamboo and the fact that it is not uprooted during harvesting means bamboo actually helps preserve soil and prevent soil erosion. It is reported to yield ~6–10 tons of dry matter per acre, nine times the yield of wood. The water‐retting process is initiated by aerobic bacteria; as the air in the rettery … Field retting is an industrial process for extracting valuable bast fibres from hemp. The two varieties of jute are white jute corchorus capsularis or Indian jute and Tossa jute corchorus olitorius, which is Afro-Arabic jute. These include linseed oil for linoleum, soap, fuel and cattle feed. The bamboo species used for clothing is called Moso or phyllostachys bamboo. This is the most important bamboo type in China, where it covers about 3 million hectares. Fabric made from ramie has a thick and thin horizontal appearance giving it many of the visual characteristics of linen and it is often used as a linen alternative, as it costs far less to produce. One hectare of bamboo can sequester 62 tonnes of carbon dioxide per year while one hectare of young forest only sequesters 15 tonnes of carbon dioxide per year. Years of selective breeding have produced many different varieties. Microbes are also important in agriculture for the compost and fertilizer production. Bast fibres, like linen and flax are obtained from the phloem, or inner bark (or skin) of a plant. Today the major producers are China and India. The fibers are loosened in a few hours, but close control is required to prevent deterioration and damage to the fibres. It is used in areas of internal body parts where its strength and lightness of weight make the vehicles more fuel-efficient and thus a better ecological proposition.
