(a) Explain the process of retting. (b) Mention the sources and uses of the following fibres.(i) Cotton(ii) Silk​

Answer»

the process of rettingWater rettingThe most widely practiced method of retting, water retting, is performed by submerging bundles of stalks in water. 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. Retting time must be carefully judged; under-retting makes separation difficult, and over-retting weakens the fibre. In double retting, a gentle process producing excellent fibre, the stalks are removed from the water before retting is completed, dried for several months, then retted again.Natural water retting employs stagnant or slow-moving waters, such as ponds, bogs, and slow streams and rivers. The stalk bundles are weighted down, usually with stones or wood, for about 8 to 14 days, depending upon water temperature and mineral content.Tank retting, by contrast, employs vats usually made of concrete, requires about four to six days, and is feasible in any season. In the first six to eight hours, called the leaching period, much of the dirt and colouring matter is removed by the water, which is usually changed to assure clean fibre. Waste retting water, which requires treatment to reduce harmful toxic elements before its release, is rich in plant minerals, such as nitrates, and can be used as liquid fertilizer.Dew rettingThis is a common method in areas with limited water resources. It is most effective in climates with HEAVY night time dews and warm daytime temperatures. The harvested plant stalks are spread evenly in grassy fields, where the combined action of bacteria, sun, air, and dew produces fermentation, dissolving much of the stem material surrounding the fibre bundles. WITHIN two to three weeks, depending upon climatic conditions, the fibre can be separated. Dew-retted fibre is generally darker in color and of poorer quality than water-retted fibre.After rettingThe retted stalks, called straw, are dried in open air or by mechanical means, and are frequently stored for a short period to allow "curing" to occur, facilitating fibre removal. Final separation of the fibre is ACCOMPLISHED by a breaking process in which the brittle woody portion of the straw is broken, either by hand or by passing through rollers, followed by the scutching operation, which removes the broken woody pieces (shives) by beating or scraping. Some machines combine breaking and scutching operations. Waste material from the first scutching, CONSISTING of shives and short fibres, is usually treated a second time. The short fibre or tow thus obtained is frequently used in paper manufacture, and the shives may serve as fuel to heat the retting water or may be made into wallboard and to make ropemention the sources and uses of the following fibres. cottonCotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost PURE cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.It is basically used for every type of clothing from jackets to normal shirts. In home,it finds its use in bed sheets and curtains. Its seed oil is used in food and cosmetics. It is also used in coffee filters.silkSilk is mainly used in the manufacture of clothing such as dresses, ties, shirts, trousers, pajamas, underwear and folk costumes. ... Silk is also used to make silk comforter or duvets which are lightweight and hypoallergenic. It is also used as fabric for upholstery, curtains, rugs and bedding such as sheets. Silk is sometimes used in the construction of parachute materials and cords, though it is more common for parachutes to be made from nylon. Silk Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity. The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors
