When the jute plant is in the flowering stage, it is harvested. Amongst the bast fibre crops, kenaf apparently has some advantages such as lower cost of production, higher fibre yields, and greater flexibility as … Jute fibre quality depends to a large extent on the bio-chemical process of retting. ... Retting process: Retting is the bacterial decomposing of natural glues that adhere the bast fiber to the herd. Retting is a process in which the tight bundles of jute stalks are taken to the tank by which the fibres get separated from the wooden stalk. The soft tissues are removed from the fibre plant with the help of bacteria. Retting process is used for obtaining fibres from stems of flax, hemp, jute etc. The retting process is completed in 8 to 30 days, when the barks separate out easily from the stick or wood and the fibres are ready for extraction. It is thus a lignocellulosic fiber that is partially a textile fiber and partially wood. Why the process of retting is needed in process of harvesting jute? The hard fibres are obtained by decortication and the soft fibres by ginning process as the machines remove the product from the plant. Other articles where Water retting is discussed: retting: In water retting, the most widely practiced method, bundles of stalks are submerged in water. mdfarooq78 mdfarooq78 16.09.2018 The fate of a good jute and mesta crop in the field for quality fibre production depends fully on the proper retting carried out in good quality water. 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. different types of retting processes used for bast plants such as hemp, jute, flax, and kenaf, with an emphasis on kenaf. A development in recent years is adoption of ribbon retting technology in jute growing trade of the country. Fibre to Fabric Class 6 Extra Questions Value Based (VBQs) Question 1. Microbes are used in retting to obtain bast fibres. Answer: Process of retting helps in separation of pulpy material of the stem from the jute fibres. The ideal climate for growing jute is warm and wet, which is offered by the monsoon climate during the fall season, immediately followed by summer.. Jute requires 2–3 inches of rainfall weekly with extra needed during the sowing period. Class VI students were going to a picnic in the month of June. Retting softens the stalks and makes it possible to separate the fibrous material from the unusable material by hand. Example:Jute is associated with the process of Retting. Jute fibers are composed primarily of cellulose (a major component of plant fiber) and lignin (major component wood fiber). Retting is facilitated by anaerobic butyric acid bacteria such as Clostridium botulinum, Clostridium tetani and Clostridium perfringens. A process called retting is used to remove the non-fibrous material from the stem and skin of the jute stalk. 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. If retting is properly carried out, the extracted fibre should exhibit genetic quality of … For this purpose, stems of fibre yielding plants are immersed in water for long period where decomposition sets in.
