Jute fiber develops in the phloem or bast region of the stem of the plants; in transverse sections of the stem. 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).In these dicotyledonous plants, the commercial fibres are sclerenchyma cells with copious secondary wall thickening (Kundu, 1944; Fahn, … It supports the conductive cells of the phloem and provides strength to the stem.

INTRODUCTION Phloem (or bast) fibres are a common source of commercial fibres and are produced from several plant species, includ-ing Corchorus capsularis and C. olitorius (jute), Linus usitatissimum (flax), Boehmeria nivea (ramie) and others Degumming by chemicals and retting in water have negative environmental effects. The straight slender stems can grow up to 4m tall. Jute" is the name of the plant or fiber used to make burlap, hessian or gunny cloth. 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. 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. As all bast fibres contain non-cellulose matter such as pectin, lignin, and hemicellulose, degumming or retting is needed to remove the non-cellulose matter. Jute is a bast fibre obtained from the secondary phloem. The industrial term for jute fiber is raw jute. 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. 3.

They appear as wedge-shaped bundles of cells intermingled with parenchyma cells and other soft tissue. Define bast fiber. 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. Bast, also known as phloem fiber, is produced from the inner bark, or bast, portion of the stem of certain plants. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells. Fibre from C. olitorius, an upland species with long pods, is but little inferior. The colour of the stem, petiole, leaf and pod varies in different forms. 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 , ramie, etc. It supports the conductive cells of the phloem and provides strength to the stem. Most bast fibers are quite strong and are widely used in the manufacture of ropes and twines, bagging materials, and heavy-duty industrial fabrics.

Extraction of Jute Fibers. Jute is one of the most affordable 100% natural fibers and it is second only to cotton in amount produced. is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall. They support the conductive cells of the phloem and provide strength to the stem. The bast fibre is obtained from C. capsularis, a species with round pods which is grown in lowland areas subject to inundation. The fiber is around the outside of the plant and comprises one-third of the weight. Commercially useful bast fibers include flax, hemp, jute, kenaf, ramie, and nettle. A. Ramie Related Posts. Key words: Jute, Corchorus capsularis , vascular development, mutant, secondary phloem fibre, lignin. Contact Share. Such fibres, usually characterized by fineness and flexibility, are also known as “soft” fibres, distinguishing them from the coarser, less flexible fibres of the leaf, or “hard,” fibre group. Jute is a herbaceous, little branched annual plant. It is a chief fibre-yielding annual shrub. C. Yu, in Textiles and Fashion, 2015. Botanically, the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. common sources of jute are hemp, flax etc. 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 , ramie, etc. Bast fibre, soft, woody fibre obtained from stems of dicotyledonous plants (flowering plants with net-veined leaves) and used for textiles and cordage. The industrial term for jute fiber is raw jute. It has a taproot system with lateral branches. Jute fiber is a secondary phloem fiber or bast fiber obtained from the bark of the stem.

The best fibres occur in the outer portion of the stem, interspersed with thin-walled tissues of phloem. Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. The secondary phloic fibres, which are the derivatives of vascular cambium, are found lacking, though there is formation of secondary phloem pyramids from the cambial tissue. 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. " We generated the bast transcriptomes of a deficient lignified phloem fibre mutant and its wild-type jute (Corchorus capsularis) using Illumina paired-end sequencing.
