Jute fibers are composed primarily of the plant materials cellulose and lignin. Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the "inner bark", sometimes called "skin") or bast surrounding the stem of certain dicotyledonous plants.It supports the conductive cells of the phloem and provides strength to the stem. It is produced from flowering plants in the genus Corchorus, which is in the mallow family Malvaceae.The primary source of the fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis.. “Jute” is the name of the plant or fiber used to make burlap, hessian or gunny cloth. 33. A) Ginning done clear. Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the 'inner bark', sometimes called 'skin') or bast surrounding the stem of certain dicotyledonous plants. Bast fibres from phloem are called jute. Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. Jute fibers are composed primarily of the plant materials cellulose and lignin. The bast constitutes 40% of the plant. is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall. Which of the process is used to extract fibre from flax and jute . The industrial term for jute fiber is raw jute. Kenaf is cultivated for its fiber in India, Bangladesh, U.S., Indonesia, Malaysia, South Africa, Viet Nam, Thailand, and parts of Africa, and to a small extent in southeast Europe. C) ... the bast fibre or phloem fibres are obtained from [BHU 1979, 89; AIIMS 1982; MP PMT 1989; CPMT 1991] A) ... Bast fibres from secondary phloem done clear. It is produced from flowering plants in the genus Corchorus, which is in the mallow family Malvaceae.The primary source of the fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis. " Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. Java Jute (Indonesia) Ambari (Taiwan) Roselle (Africa) The fiber in Kenaf is found in the bast (bark) and core (wood). B) Laping done clear. Chlorosis is produced in the leaves due to the deficiency of Fe, Mg, Mn, S or N of View Solution play_arrow; Jute is an annual herbaceous dicotyledonous plant that grows to a height of 1.5–4.5 m. The stems are about 1–2 cm in diameter with few branches. The two species differ in the quality of fibre they yield. Jute fibre is obtained from the bast or phloem layer of the stem. It supports the conductive cells of the phloem and provides strength to the stem. Jute" is the name of the plant or fiber used to make burlap, hessian or gunny cloth. Phloem (or bast) fibres are a common source of commercial fibres and are produced from several plant species, including Corchorus capsularis and C. olitorius (jute), Linus usitatissimum (flax), Boehmeria nivea (ramie) and others (Kirby, 1963). Bast fibre development in jute (Corchorus spp.) It falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax (linen), ramie, etc. The colour of the stem, petiole, leaf and pod varies in different forms. There are secondary phloem cells. The bast fibers can be used to make textiles that are 100% hemp, but they are commonly blended with other fibers, such as flax, cotton or silk, as well as virgin and recycled polyester, to make woven fabrics for apparel and furnishings. The industrial term for jute fiber is raw jute. Botanically, the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. (D) Bast fibre from primary phloem Solution: (C) Fibres are elongated cells with usually lignified, walls. It falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax (linen), ramie, etc.
