Main exporting countries (in order of importance) Achigan-Dako. Weaving is the process of producing fabric by interlacing one set of yarn with another set at right angles, usually by means of a loom. Lignin is a complex aromatic polymer, often present in the middle lamella and the mature secondary wall (Biermann, 1993; McDougall et al., 1993). cordage, fishing nets, Corchorus capsularis The properties of paper-based products are to a large extent determined by the types of pulp from which they are manufactured, whereas the properties of the pulp are determined by the properties of the raw material (fibre dimensions, chemical composition) and the pulping process used (Hague, 1997). Apart from these parts of plants, we get plant fibers from grass, wood etc. Other potential uses include geotextiles for erosion control on slopes and for agricultural mulching. Often palm leaves are applied, either harvested from wild trees, e.g. In book: ... but gradually replaced due to short, coarse and weak fiber and undesirable boll and plant … January 1970; DOI: 10.1007/978-3-642-04796-1_1. It is naturally smooth and straight. perennial herb in Germany (Groot, 1996). Actinoscirpus grossus RUSSIAN JOURNAL OF PLANT PHYSIOLOGY Vol. It is also a natural fiber. These conditions accelerate degradation of the fibre in the composite. Particle board is manufactured by hot-pressing pre-formed mattresses consisting of fibrous particles blended with resin and wax. 270-400 × 75-100 (double rows; The use of timber for construction purposes has been dealt with in the Prosea volumes on timber trees. Pro Lite, Vedantu IND great bulrush Hemp, ramie, cotton, and rag fibres from plant or animal origin have been used for paper making for almost 2000 years (Croon, 1995; McDougall et al., 1993). Most rope consists of 3 strands twisted in a right-hand direction. weaving, Colona javanica Fibre Plants - seed, bast & hard fibres: Plant Fibre from cotton, linen, hemp & jute. Pandanus atrocarpus ex L.) J.F. The fibres, which form the subject matter of this lesson, are the basis of clothing and therefore their importance cannot be overemphasized. These include species producing the well-known plant fibres of international trade such as cotton (Gossypium spp. Lower yields, partly because of the lack of research and development work on lesser-known species. and packing. A special case is Enhalus acoroides, which is subaquatic. Introduction to Fibres, Lecture 1 . This introductory lecture is meant to bring the class to a common wavelength so future understanding of the course is built on coherent concepts. Albizia falcataria (L.) Fosb.) vol. The time required depends on temperature and varies widely. 4000-7200 Although naturally occurring plants have been important sources of fibre since the beginning of history, it is desirable for a viable industry to be able to obtain raw material from sustainable and well-managed farmers' plots or industrial plantations. Fibres in general are defined as "slender strands of natural or man-made material... Role of fibre plants. The specific combination of treatment time, temperature, the alkali type and its concentration, are usually proprietary information (McDougall et al., 1993; Wood, 1997). leaf fibre, Gramineae weaving, thatching, Pandanus odoratissimus If you want to know more about fibers then register yourself on Vedantu or download Vedantu learning app for Class 6-10 IIT- JEE & NEET. Important fibre plants treated in other PROSEA volumes. sucker shoots, stem cuttings, seed, Phragmites vallatoria Fibres to be used for textile production are often subjected to additional chemical treatment to remove these compounds. periuk kera CAM Many types of linkages between the monomers have been found, but the β-O-4 aryl ether is the most common. Thatches are roof coverings made from non-wood plant material such as leaves, straw and reeds. In general the most important textile and cordage fibre-yielding families are the Malvaceae (cotton, kenaf, roselle) and Tiliaceae (jute). Ressources végétales de l'Afrique tropicale. United States, Canada, India, China, Australia, Argentina, Jute and allied fibres Sisal bast fibre, Araliaceae have potential in the market for specialty papers. Monocarpic perennials such as sisal and cantala form fewer leaves per year and have a longer life cycle under dry conditions or at low average temperatures. Wool... Properties. Industrial plantations of major crops in South-East Asia include those of cotton, abaca, ramie, kenaf, roselle, jute, cantala and sisal, the extent of which differs from country to country and depends on the requirements of domestic and export needs. Heliconia indica Lamk). 1000-3000, Roselle To begin the extraction of the vascular bundles, a variety of stems need to be soaked in water for around a week. Many of the species treated in this volume are important only at a very restricted or local level. They include most commercial textile fibres and many local fibres such as Colona javanica (Blume) Burret, Curculigo spp. Sri Lanka Yeah! Cotton is basically a perennial plant with an indeterminate growth habit, but it is usually grown as an annual, with the formation of nodes on the main stem arrested by fruit load, temperature, soil moisture, photoperiod, or a combination of these factors. <1 textile, paper, Miscanthus floridulus clones (rhizome cuttings). Where temperature and humidity are high and there is little wind, stems can be dew-retted in the field. cordage, mats, brushes, thatching, weaving, Crotalaria juncea Brazil The state of art on vegetable fibre treatments and the description of processes constitute Section 3. flax), and during the early stages of development for most crops. (%). from Borassus flabellifer, Cocos nucifera, Metroxylon sagu and Nypa fruticans. Examples are bamboo, and textile and cordage fibres, e.g. LAO In the case of fibre plants, active collection and conservation of genetic resources is limited to the economically most important crops. Old hemp clothing was one of the earliest materials to be used for paper making (Wood, 1997). The principal semi-chemical pulping process is the neutral sulphite semi-chemical process (NSSC), which involves chemical pretreatment followed by refining (Hague, 1997; Moore, 1996). suckers, corms, seed, in vitro culture, Pandanus spp. Coir and the leaf stalks of Cocos nucifera and Borassus flabellifer, for instance, possess fibres characterized by low length:width ratio of fibre cells and thick cell walls (Maiti, 1997). Development of mechanical harvesting methods, preferably combined with fibre extraction. Cotton, jute, flax etc. Long strands of molecules interwoven to form a linear, string-like structure are known as ‘Fibres’. The choice of material for thatching depends on local availability: cogon grass (Imperata cylindrica (L.) Raeuschel) is widespread and is often used. Other sources of barkcloth in South-East Asia include Artocarpus elasticus Reinw. Sources: FAO databases; estimations by various authors. Environmental concern has resulted in a renewed interest in bio-based materials. High-quality fibres like cotton, ramie, flax and hemp contain very little (less than 5%) lignin, whereas jute, kenaf and roselle generally contain 10-20% lignin, making them inferior for fine fabrics (Palit et al., 2001). Table 11. textile, Heliconia indica Pectin Some advantages of non-wood fibres over wood fibres are (Moore, 1996): Disadvantages of non-wood fibres compared to wood fibres include (Moore, 1996): Potential paper-making species for South-East Asia include jute, kenaf, roselle, paper mulberry, Arundo donax, Helicteres isora, and Miscanthus spp. perennial herb cotton and kapok. In sisal, for instance, about 20-25 leaves are left on the plant at the first cutting, which is usually decreased to 15-20 leaves at subsequent cuttings. Eugeissona triste Griff.) fruit fibre, Cyclanthaceae leaf, Cyperaceae The pectin content of important fibres is for unretted flax 4%, retted flax 2%, ramie 2%, sisal 1%, hemp 0.8% and jute 0.2% (Table 6). thatching, weaving, Curculigo capitulata Phormium tenax For a yield of about 1.7 t/ha seed cotton, the uptake is about 105 kg N, 18 kg P and 66 kg K per ha (Halevy & Bazelet, 1989). Russian Federation Belarus Physical properties of selected plant fibres. In grasses, nodes are often unwanted and need to be separated out. The majority of the fibre plants treated in this volume, including abaca, cantala, coir, Congo jute, cotton, jute, kapok, roselle and sisal, grow best at average temperatures of about 25 °C. Principal germplasm repository and/or coordinator1 China Design and Development of Natural Plant Fibre Extracting Machine INTRODUCTION. Hutch. It is used in numerous fields in various ways. Various developments during the 20th Century have led to a decline in the importance of non-wood fibres other than cotton: the mechanization of production and thus increased market share of cotton, the development of synthetic fibres from petroleum (nylon, acrylic, terylene, polyester) or from cellulose contained in living plants (viscose, acetate, tri-acetate), and a decline in the use of sacking for the transport of agricultural products due to the advent of transport in containers (Lewington, 1990; Wood, 1997). In flax, kenaf and roselle, for instance, stems are left to defoliate in the field after harvesting. Cotton, kapok, and coir are examples of fibres originating as hairs borne on the seeds or inner walls of the fruit, where each fibre consists of a single, long, narrow cell. globular fimbristylis Paper can be made from any natural fibrous material, including wood fibres, cereal straw, bamboo and textile fibres used in either the raw or manufactured state. World paper consumption rose steadily from 40 million t in 1950 to 226 million t in 1988, an average increase of 4.7% per year. A simple method is to pass dried stems through a sloping rotating cylinder with bars that abrade the material as it passes through the cylinder. Fabrics include cloth for clothing and domestic use, and also coarser materials such as burlap for sacking. Control of diseases and pests includes cultural, chemical and biological methods. The cultivars are clones developed from single plants selected within open-pollinated seedling progenies of existing varieties, or populations following intra- and interspecific hybridization. 1.1 Introduction Food, clothing and shelter are the three basic needs of human beings. ex Blume and Antiaris toxicaria Lesch. We get plant fibers from plants such as from jute plants we get jute fiber and we obtain cotton fiber from cotton plants etc. In general, jute and kenaf require about 100-125 mm per month, flax 150-200 mm, Congo jute 160-210 and roselle 150-270 mm. 1000-2000, Hemp In the 18th and 19th centuries, the Industrial Revolution encouraged the further invention of machines for use in processing various natural fibres, resulting in a tremendous upsurge in fibre production. Strength or tenacity is a measure of resistance to steady forces, and is the appropriate quantity to consider when material is subject to a steady pull, for instance in the case of a rope used for hoisting heavy weights (Morton & Hearle, 1993). The "hard fibres" include fibres from the vascular bundles in the leaves of, Entire leaves or leaf strips: used for plaiting and weaving (, Cotton: photoperiod-insensitivity, early crop maturity, adaptation to mechanical harvesting (in industrialized countries), high quality lint fibre (length, fineness and strength), seed quality (oil content and low gossypol content by glandless plants), resistance to diseases (e.g. Large stocks and adequate storage at constant quality by drying or ensilage may be necessary to service large-scale operations. Spain CSIRO, Australia IMCs find application in plaster boards, tiles, concrete, mortars and plasters. (1.2-)1.9-3.1(-6.3) After drying, the fibres are brushed mechanically to remove dust and other matter and to increase the lustre. This is done in different ways depending on the fiber classification. Plant fibres are elongated most commonly sclerenchyma supportive plant cells with thick cellulose walls with a well-organised structure. The resulting pulp contains cellulose, hemicelluloses and lignin. (1991) and uses a wider definition of fibre plants, which are considered to comprise: In the present Prosea volume 72 species are described in detail in the 45 major treatments of Chapter 2. ), but many other plant fibres are useful as filling material, such as Bombax anceps Pierre, B. ceiba L., the straw of cereals and other grasses, and the husks of maize. Various parts of plants like woody core, bast, leaf, cane, straw from cereals, grass and seed can be used in applications like building materials, particleboards, insulation boards, human food and animal feed, cosmetics, medicine and sources of other bio-polymers and "fine chemicals". shrub Thailand, Ramie collection and characterization of abaca germplasm, production and processing. It is soft, fluffy fiber. akar katam Most annual fibre plants, including cotton, flax, hemp, jute, kenaf, roselle and sunn hemp, are propagated by seed. The present volume follows the commodity grouping adopted for the Prosea Handbook as presented in Jansen et al. These processes are characterized by high yields. Softwoods yield tracheids and xylem fibres, and hardwoods produce a mixture of tracheids, vessel elements and xylem fibres. 2.6.1 Introduction. Polyester Plant manufacturing operations are staggered in three production lines located within the same premises, at 38th K.M. An important bacterial disease is bacterial blight (Xanthomonas campestris pv. Created by. 1 Including kenaf, roselle, Congo jute, China jute, other Malvaceae, and sunn hemp. Breeding objectives for the most important fibre crops include, in addition to the general aim of higher yields: Plant biotechnology is providing powerful new tools for plant breeding with the potential to increase selection efficiency and creating new approaches to hitherto unattainable objectives. In the manufacture of rope, lengths of fibre are spun into yarns, which are twisted together into strands. Species also used as fibre plants in addition to their primary use are treated in other Prosea volumes, for instance pineapple (Ananas comosus (L.) Merrill) in Prosea 2 (Edible fruits and nuts), Talipariti tiliaceum (L.) Fryxell (syn. Mauritius hemp. brushes, thatching, Of these, CTMP, using a pretreatment with 1-4% sodium sulphite, has become the most widely used. 5 Risks of early breakdown of host resistance due to the occurrence of new biotypes of the pest appear lower than assumed initially (Tabashnik et al., 2000). The fibre cells of ramie are the longest of all the vegetable fibres, followed by cotton, flax and hemp. Industrial Applications of Natural Fibres examines the different steps of processing, from natural generation, fibre separation and fibre processing, to the manufacturing of the final product. Leaf fibres – the natural fibres that can be collected from the leaves of certain plants. Examples are nylon, rayon, polyester, and acrylic. Chemical properties of selected plant fibres. Direct burial 3. perennial grass Various sources. Examples are oxygenated agents such as O2/OH-, H2O2 and O3. These monomers are based on coumaryl alcohol and may have 1 or 2 methoxyl groups at C-3 and/or C-5 on the benzenoid ring (McDougall et al., 1993; Palit et al., 2001). A prerequisite to such a QTL analysis is the availability of a saturated genetic linkage map (Mohan et al., 1997). Many pulping processes have been developed to convert raw materials into separated fibres suitable for use in paper making. Fibre Industry Development Authority (FIDA), Department of Agriculture (DA), Quezon City: all aspects: propagation, production, utilization, etc. Jute and similar fibres are traditionally used for carpet backing, carpet underlays and for the manufacture of felt. Cotton, however, may be grown under irrigated or rainfed conditions. Width For annual fibre crops, the rainfall during the growing season is more important than the total annual rainfall, with cotton, for instance, needing at least 500 mm during the growing season. Tolerance to herbicides (e.g. ratio, Abaca The brush fibres include African piassava (from Raphia hookeri G. Mann & H. Wendl. Wikstroemia spp. IAC, Brazil Environmental concern has resulted in a renewed interest in bio-based materials. Annual bast fibre plants are usually harvested manually, by cutting or pulling. This latter collection is regularly evaluated and rejuvenated in grow-outs at a seed multiplication centre in Costa Rica (Hau, 1999). 300 For the production of burlap bags jute is superior in quality to kenaf, because it possesses fibre cells with more uniform morphology. Lignification increases the rigidity of the cell wall, makes it less susceptible to predation and less permeable to water (McDougall et al., 1993). & D.A. It is also a seed fiber like cotton fiber. An overview of important fibre plants with other primary use is presented in Table 2. It is generally considered to be pure cellulose, but it actually is 96-98% cellulose (Biermann, 1993). Arundo donax L., for example, grows at average annual temperatures between 9 and 29 °C and an annual rainfall of 300-4000 mm. The main components of plant fibres are cellulose, non-cellulosic polysaccharides (NCP), often subdivided into hemicelluloses (mainly composed of neutral sugar residues) and pectin (characterized by a high content of D-galacturonic acid residues), and lignin (Biermann, 1993; McDougall et al., 1993). sacking, cordage, Corypha utan It is one of the most affordable fibers. Sri Lanka Examples are cereal straw, bamboo, bagasse from sugar cane, and the stems of reeds such as, Entire or split stems: used for plaiting and weaving (many, Pith: sometimes used for paper making, e.g. The main fibre used in 1999 was flax (11 000 t), but kenaf (1100 t), hemp (1100 t), jute (700 t) and sisal (500 t) were also used (Karus & Kaup, 1999). Fertilizer recommendations depend on soil characteristics and nutrient uptake of the fibre crop. The resin most commonly used to bind particles together in particle board and MDF is urea formaldehyde (UF). These characteristics usually vary widely within species, even between fibre strands within the same plant. Modern cotton cultivars are generally photoperiod-insensitive. The choice of the appropriate pulping process depends on the raw material to be pulped and the grade of paper or board product to be made from it (Moore, 1996). Linum usitatissimum China, Jute-like fibres1 Germplasm collections are maintained by national agricultural research systems in the main producing countries for each of the remaining 4 fibre crops. to include those plants from which fibres are extracted and used to make textiles, cordage, and sometimes also paper (Lipton, 1995; Wood, 1997). Pro Lite, Vedantu Fibre hemp, flax, Juncus effusus, Miscanthus spp., Phormium tenax and Tetrapanax papyriferus (Hook.) Thailand Each step is linked to fibre properties and characterization, highlighting how different fibres influence the product properties through a discussion of their chemical and structural qualities. The pulping methods can be divided into three main processes: chemical, mechanical and semi-chemical. Originally cotton was used, because of its high cellulose content, but it has almost entirely been replaced by wood fibres (McDougall et al., 1993). Knowing the identity of the fibre(s) is also helpful in planning appropriate conservation treatment(s) and/or storage methods. Many plant species are traditionally used for tying without much processing, for instance the stems and branches of lianas such as Bauhinia and Gnetum spp. Important physical properties of plant fibres include strength, durability, cohesiveness (the ability of individual fibres to stick together when spun into yarn), pliability (the quality enabling the filaments to be wrapped around each other during spinning), and colour (Weindling, 1947). Domin, Scirpodendron ghaeri (Gaertn.) annual or perennial (sub)shrub The fibre is subjected to a special combing operation ("hackling") prior to spinning (Simpson & Conner Ogorzaly, 1995; Wood, 1997). pandan laut wine palm Main producing countries (in order of importance) Non textile weaving encompasses a number of different techniques such as plaiting, twining, coiling and wickerwork. Sometimes ferulic and p-coumaric esters are found (McDougall et al., 1993). Jute, for instance, is harvested at mid-flowering; earlier harvesting results in lower yields of fine fibre, whereas later harvesting results in higher yields, but a coarser and lower-quality fibre. The physical properties of plant fibres are a function of the properties of the individual fibre cells and those of the matrix of intercellular cementing materials in which the fibre cells are embedded (Mukherjee & Radhakrishnan, 1972). All the above-mentioned options of molecular breeding are being applied to cotton with considerable success (Hau, 1999; Kohel et al., 2001). toddy palm Ginning is applied to seed fibres such as those from cotton. and R. palma-pinus (Gaertn.) Plants are good source of industrial inputs and among one is fibre industry (agroindustry). The nutrient uptake of flax, for instance, is relatively low: for a crop yielding 5-6 t straw and 0.6-0.8 t seed per ha it is 50-75 kg N, 10-16 kg P and 40-60 kg K.
