Gravity. 3-4 have only a 30% fibre fraction and flax a 20% usable bast fibre. About 450 plant species whose use as fibre plants is secondary to other uses are listed in Chapter 4. 663 3 2010 PLANT FIBERS: INITIATION, GROWTH, MODEL PLANTS 307 no such system for fibers (or sclereids). 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). pandan laut Forest Research Institute Malaysia (FRIM), Kepong: utilization of kenaf for pulp and paper and composite products. Species collected from the wild are sometimes over-exploited and may be threatened with extinction, especially those with restricted and endemic distribution such as some Pandanus spp. (10-)12-25(-44) Many trees used to supply pulp for paper making, including Acacia auriculiformis A. Cunn. Sometimes whole twigs, fine stems or roots are utilized; fibres are also obtained from leaf stalks of palms. Of the 72 major fibre plants treated in this volume, 44 mainly yield stem material, 25 are mainly exploited for their leaves (including leaf sheaths), and 5 provide seed or fruit fibres (Table 9). The fibre is subjected to a special combing operation ("hackling") prior to spinning (Simpson & Conner Ogorzaly, 1995; Wood, 1997). stem, Cyperus malaccensis leaf fibre, Furcraea foetida For many thousand years, the usage of fibre was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. broadcast bacterial blight and, Jute: early crop maturity and low photoperiod-sensitivity, finer and whiter fibre quality, resistance to diseases (. Machines of this type have been developed for kenaf in the United States. Wikstroemia spp. Rough fibres such as those of Furcraea spp., Abelmoschus esculentus (L.) Moench and Hibiscus radiatus Cav., as well as several other Agave spp., also have the desirable qualities (Maiti, 1997). The breeding plans applied to a particular crop species are very much determined by its life cycle (annual or perennial), mating system (self- or cross-pollinating) and methods of multiplication. Malaysian Institute for Nuclear Technology (MINT), Kajang: utilization of kenaf for pulp and paper and composite products. Recovery of the active chemicals is an important environmental and economic consideration. The cellulose molecule of purified cotton consists of at least 2000-3000 simple glucose sugar molecule residues, joined end to end in the form of a long chain (Kirby, 1963). Softwood ultimate fibres are 2.7-4.6 mm long and hardwood ultimate fibres have a length of 0.7-1.6 mm (Karakus et al., 2001). Most animals that produce textile fibers are mammals. By using our services, you agree to our use of cookies. Sugar-cane bagasse has been considered as a source of raw material in various Asian countries, including Thailand and India. All the 11 Cyperaceae are perennial herbs, whereas the 10 Malvaceae are herbs, shrubs or trees (Table 9). in Germany (Groot, 1996). Common plant spacings and densities for selected fibre crops. Semi-chemical pulping processes consist of a chemical and a mechanical pulping stage. 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. 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. parasitica) on kenaf and roselle, Fusarium wilt on cotton, abaca, kenaf and roselle, and Verticillium wilt on cotton. Department of Agriculture: research and development on cotton, jute and jute like fibre, kenaf; technology transfer to extensionists, farmers and companies. Different fibre crops and the fibres obtained from them are mentioned below: Many plants that are a ch source of fibres produce bast fibres, seed fibres and leaf fibres. Department of Agricultural Extension: development and transfer of the fibre plant production practices to farmers. leaf, leaf fibre, Hydrocharitaceae Hardwoods are commonly pulped using the NSSC process, with the pulps particularly suitable for use in packaging grades of paper, e.g. platters, packing, Helicteres isora Current applications of non-wood plant fibres in building material include particle board, fibreboard, especially medium density fibreboard (MDF), and inorganic matrix composites (IMCs). 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. Statistics on the production of flax and hemp in South-East Asia are not available, but fibre production of these crops is limited in the region. 2.1 Essential properties ; 2.2 Other important properties ; cotton-m3. India Pro Lite, Vedantu Usually older or otherwise tougher, less supple strands are used for mats, whereas more supple strands are used for baskets, chairs and other forms of wickerwork. leaf, Cyperaceae Export bast fibre, Thymelaeaceae The three most important fibre crops (cotton, jute and its allied fibres kenaf and roselle, flax) are predominantly self-pollinating annual species which are multiplied by seed. The explanation for the popularity of wood is its low cost and high fibre quality. bast fibre, Araliaceae Disadvantages of mechanical processes are the high energy demand and the damage caused to the fibres; they generally cause severe shortening of fibre length (Moore, 1996; Sabharwal et al., 1995). Non textile weaving encompasses a number of different techniques such as plaiting, twining, coiling and wickerwork. Forms include groundwood, lacebark, thermomechanical pulp (TMP), and bleached or unbleached kraft or sulfite pulps. Properties Jute is a long, soft, shiny vegetable fibre that can be spun into coarse, strong threads. Table 2. Traces of natural fibres have been located to ancient civilizations all over the globe. The most important cordage fibres are abaca (Musa textilis Née), sisal and hemp; lesser-known but nevertheless widely distributed cordage plants include Abroma augusta (L.) L.f., Helicteres isora L., Malachra capitata (L.) L., Sansevieria spp. Many fibre plants are propagated by seed but a range of vegetative methods are employed as well (Table 10). Decreased use of forest resources and, where fibres are extracted from agricultural wastes, less emissions of carbon monoxide and carbon dioxide arising from the burning of these waste products). The most valuable of all stuffing materials is kapok (Ceiba pentandra (L.) Gaertn. ), caulking (seams between planks, barrels etc.) (1-)10-40(-85) flax), and during the early stages of development for most crops. perennial grass The processes differ in their nature and the pulp yield obtained. The cellobiose chains are mutually connected by hydrogen bonds (McDougall et al., 1993). Plaits are wide, flat, pliable, fibrous strands that are interlaced to make hats, sandals, baskets, chair seats, mats, etc. Plant fibres are obtained from various parts of plants, such as the seeds (cotton, kapok, milkweed), stems (flax, jute, hemp, ramie, kenaf, nettle, bamboo), and leaves (sisal, manila, abaca), fruit (coir) and other grass fibres. Across all countries, the export fraction does not exceed 35% of total production; this means that the largest proportion of the fibres produced worldwide is consumed domestically. The resin most commonly used to bind particles together in particle board and MDF is urea formaldehyde (UF). brushes, thatching, great bulrush Of the 72 fibre plants, 39 are mainly used for cordage or tying, 28 for plaiting and weaving, 13 for thatching, 11 for textiles (including sacks), 10 for paper making, 3 for brushes and mats, 3 for miscellaneous uses (packing), 2 for natural fabrics and 1 for filling (stuffing). The retted stems of flax and hemp are dried, after which they are passed through fluted rollers to break the core into pieces of woody matter called "shiv" that remain attached to the fibre. giant bulrush Numerous species of rattan and bamboo are used in basketry, as are many Cyperaceae, Palmae and Pandanaceae. Indonesia Wheat, rice and sorghum, from which residues are used for paper making, are treated in Prosea 10 (Cereals). perennial grass Other sources of barkcloth in South-East Asia include Artocarpus elasticus Reinw. thatching, Nepenthes ampullaria The initial retting process aims to degrade the stem tissue that interconnects the fibre bundles, and this is done … abaca Those composed of cellulose and lignin are considered vegetable or plant fibers. weaving, Schoenoplectus litoralis weaving, thatching, Phormium tenax Once bleached, paper pulp, while still hydrated, may be beaten to give a fluffy, highly absorbent fibre suitable for sanitary products (McDougall et al., 1993). par M. Brink & E.G. It normally involves the immersion of bundles of stems in ponds or streams. Area Spain Current use of cotton hybrids is limited to South Asia and China, where seed production by manual emasculation and pollination is economically feasible due to low labour costs (Hau et al., 1997). 0 It is a very good absorbent. Probably the best known of these barkcloths is "tapa cloth", obtained from the bark of paper mulberry (Broussonetia papyrifera (L.) L'Hér. weaving, thatching, Urena lobata The fibres are usually glass, carbon, or aramid, although other fibres such as paper or wood or asbestos have been sometimes used. Paper making spread from China to India, Persia and Arabia, and from there through Spain into Europe in the 12th Century (Hill, 1952; Simpson & Conner Ogorzaly, 1995). Product improvement, product diversification and waste utilization. For cordage, rough fibres are used in general, such as abaca and sisal. ex Blume and Antiaris toxicaria Lesch. ), Congo jute (Urena lobata L.), other Malvaceae, and sunn hemp (Crotalaria juncea L.). Principal germplasm repository and/or coordinator1 90-100 cm between rows of each pair) thatching, tying, weaving, Raphia hookeri This difference in chemical composition affects properties such as the resistance to washing in hot water and the acceptance of dyes. Fibre-reinforced polymer (FRP), also Fibre-reinforced plastic, is a composite material made of a polymer matrix reinforced with fibres. Wood fibres: the fibres occurring inside the vascular cambium of softwood or hardwood stems. New Zealand flax Do you know from where we get that? Bristle coir is the longest coir fiber. Chemical control is effective only if the timing is correct and often supplementary cultural methods are necessary. This was probably (%) Plants are good source of industrial inputs and among one is fibre industry (agroindustry). Enhalus acoroides Kapok is propagated by either seed or cuttings, and in Indonesia seedlings are grafted with high-yielding clones. Traces of natural fibres have been located to ancient civilizations all over the globe. It is also a natural fiber. width Brazil (Instituto Agronômico de Campinas (IAC), Campinas, São Paulo) has collections of ramie and sisal, the Philippines (Institute of Plant Breeding (IBP), College, Laguna; National Abaca Research Centre (NARC), Baybay, Leyte) of ramie and abaca, China (Institute of Bast Fiber Crops of the Chinese Academy of Agricultural Sciences (IBF-CAAS), Yuanjiang) of ramie, Tanzania (Mlingano Agricultural Research Station) of sisal and Indonesia (Indonesian Tobacco and Fibre Crops Research Institute (ITOFCRI), Malang) of kapok. The chemical processes separate the cellulose from the lignin, whereas the mechanical processes convert all the constituents present. paper, cordage, Wikstroemia ovata van der Vossen (genetic resources and breeding). Many kinds of cordage exist, including rope, twine, binder twine and fish lines. Ramie, for instance, contains a gummy pectinous material that is not broken down by retting, and separation of the fibre requires a chemical treatment. New Zealand flax Fibres are first spun into thread or yarn and then woven or knitted into fabrics. Another useful characteristic is the elongation at break, which is a measure of the resistance of material to elongation. 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. The fibre cells of ramie are the longest of all the vegetable fibres, followed by cotton, flax and hemp. Jute plant is cut and kept immersed in the water for Retting process during season. Table 3 shows that cotton is by far the most important fibre crop in terms of area under cultivation, production, and export value, followed by jute and flax. (3.7-)7-8(-12) leaf, Sterculiaceae Large stocks and adequate storage at constant quality by drying or ensilage may be necessary to service large-scale operations. University Putra Malaysia (UPM), Serdang: utilization of kenaf for composite products. plant .cotton fibre grows in the seed pod or boll of the cotton plant . Small amounts of wax are added to boards to improve their short-term resistance to thickness swelling in damp or wet environments (Hague, 1997). seed fibre, Hibiscus cannabinus Furthermore, weeds sometimes harbour diseases and pests that may be detrimental to the crop. Bast is the outer covering of stem in plants. This genebank stores and maintains about 6000 accessions, including some 4000 for jute alone (Corchorus capsularis, C. olitorius L. and other Corchorus spp.). Rooting is easily stimulated by application of growth regulators. perennial herb Brief descriptions of 129 minor species are given in Chapter 3. Juncus effusus Boehmeria nivea 14 Merr. Sometimes propagules are collected from the wild and planted in home gardens or fields, either as sole crops or as components of intercropping systems. Hat fibres are obtained from the leaves of the Panama hat palm (Carludovica palmata Ruiz & Pav.) After the Second World War, demand for plant fibres was high, but since then the demand for natural fibres (except cotton) has gradually decreased due to the development of synthetic fibres which are often cheaper to produce, more durable and easily converted into attractive designs and colours. ), Palmae (Borassus flabellifer, Cocos nucifera, Corypha utan Lamk, Eugeissona triste, Nypa fruticans) and Pandanaceae (Pandanus spp.). Softwoods are the preferred raw material for particle boards and MDF; jute and kenaf sticks are used as well. glyphosate or glufosinate) and insect resistance based on Bt genes (derived from Bacillus thuringiensis) are the main characters that have been successfully expressed and commercialized so far. Natural fabrics are often made from tree basts that are extracted from the bark in layers or sheets and pounded into rough cloth ("barkcloth"). seed (lines, F1 hybrids), Flax Brazil perennial herb Sisal is sometimes planted in a double-row system ("twin-row planting"), in which pairs of rows are alternated by wider spaces ("lanes"); the plants in the rows nearest to each other are staggered, so that they are as far apart as possible (Lock, 1969). Flax: resistance to lodging, fibre quality (fineness, strength and homogeneity), disease resistance (anthracnose. division, rhizome cuttings, seed, in vitro culture, Musa textilis The primary aim of pulping is to separate fibres and to produce a fibre surface suitable for bonding in the process of paper making (Moore, 1996). The term holocellulose refers to the entire carbohydrate fraction of the material, i.e. The Young’s modulus or modulus of elasticity is the ratio of the stress (force per unit area) or applied load to the strain or deformation produced in a material that is elastically deformed; the higher the value, the stiffer the material. 20-30 × 5-10 The soil requirements of fibre plants vary, but rich alluvial, sandy loams, loams and clayey soils are generally preferred. United Kingdom, Cotton (lint) Brazil 1494 i) Vegetable Fibres: Most of these are cellulose fibres and include cotton, linen, jute, flax, ramie, coir, sisal and hemp. clones (rhizome cuttings). Linum usitatissimum) or single as idioblasts (ex. An overview of important fibre plants with other primary use is presented in Table 2. 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). bast fibre, Corchorus olitorius weaving, Furcraea foetida Cotton is notoriously sensitive to pests, which has led to excessive spraying of insecticides. The chemical treatment typically involves the use of up to 15% sodium sulphite by mass of material, and approximately 4-5% sodium carbonate by mass. China In contrast to plant fibres, animal fibres such as wool mainly consist of protein. It was not until the introduction of wood pulp in 1843 that paper production was not dependent on recycled materials from ragpickers. seed fibre, Gossypium herbaceum It is generally considered to be pure cellulose, but it actually is 96-98% cellulose (Biermann, 1993). SE Asia perennial grass The length:width ratio is important, because it affects the paper's flexibility and resistance to rupture. PROTA, Introduction aux Plantes à fibres. Main importing countries (in order of importance), Abaca sisal textile, Gossypium herbaceum This paper highlights the physical and chemical surface modifications of plant fibre (PF) for attaining suitable properties as reinforcements in cementitious composites. 98 ... thereby contributing to a circular economy. To have a source of fiber to utilize in production, the fiber first must be extracted from the plant. Thatches are roof coverings made from non-wood plant material such as leaves, straw and reeds. lobster-claw 1.1 Introduction Food, clothing and shelter are the three basic needs of human beings. Plant Fibre is a crafting material used for furniture, blocks, and a variety of useful crafting recipes, including bandages and woven fabric.. Plant fibre is obtained by cutting vines in caves, cutting giant flowers from the Giant Flower Mini Biome, cutting thick growth in Jungle biomes, and by harvesting crops. depending on the plant. In the manufacture of rope, lengths of fibre are spun into yarns, which are twisted together into strands. suckers, bulbils, in vitro culture, Boehmeria nivea 2 These include species producing the well-known plant fibres of international trade such as cotton (Gossypium spp. (1.5-)2-3(-12) Australia Romania, Jute Fibers fall into two broad categories: natural and man-made (or synthetic). 40-130, Sisal Examples include pineapple and banana leaf fibres. China India, Thailand, Indonesia, Ramie Lower capital investment requirements for non-wood pulp and paper mills, due to smaller size and fewer technical problems. 200-250 × 80-100 (single rows) Fibre plants in a broad sense, as defined for the present volume, can be tentatively divided into 11 main groups: textiles, cordage and tying, brushes, filling, plaiting and weaving, thatching, natural fabrics, artificial fibres, paper, building and construction material, and miscellaneous uses. Cantala also prefers semi-arid conditions, though it can be grown in higher rainfall areas as well. Wild Fibres natural fibres > plant fibres. INRA, France Trichogramma chilonis) and the use of synthetic insecticides when the pest population reaches a critical level, are applied to reduce pesticide use in cotton (Pascua et al., 1997). Table 8 presents typical values of the tensile strength, elongation at break and Young's modulus of selected plant fibres. Fibres extracted by retting are still encrusted with lignins and hemicelluloses, affecting the fibre quality. Netherlands It is a long, shiny and soft fiber. 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. INTRODUCTION Fibres are thread like materials which can be used for different purposes. Russian Federation, Kapok Thailand, Ramie α-Cellulose (%) Long strands of molecules interwoven to form a linear, string-like structure are known as ‘Fibres’. 1 IPGRI is the overall coordinator for most crops. Markets where plant fibres such as jute, kenaf, roselle and sisal may gain terrain over synthetic fibres include those for insulation, packaging, geotextiles, composites, filters, sorbents and active surfaces (Bolton, 1995). Heliconia indica Lamk). Mills in Africa and Latin America mainly use wood, whereas in Asia non-wood raw materials predominate, due to (Moore, 1996): Non-wood materials used for the production of pulp can be divided into 2 categories (Wood, 1997): In temperate climates the most important source of non-wood fibre for pulping is wheat straw; in Asia, rice and wheat straws and bamboo are important sources; and in Latin America sugar-cane bagasse is by far the main non-wood fibre (Moore, 1996). F1 hybrid cultivars with considerable hybrid vigour for yield have been successfully developed during the past two decades for cotton. MAL Waste-material and by-products may also be useful, for instance sisal short fibres, poles and boles for pulping, and leaf waste for animal feed. Several species, such as kenaf, ramie and paper mulberry, also grow well at somewhat lower temperatures. MAS enables early selection of important major genes (e.g. sacking, cordage, Corchorus olitorius Fibres from coir, sisal, jute and flax are made into biodegradable plant pots, e.g. Most of the silica dissolves during cooking and remains as an undesirable component in the spent pulping liquor. (0.5-)2-2.5(-6.5) The polymerized pentoses are called pentosans. 9.4-22.0 1 BUR = Burma (Myanmar); CAM = Cambodia; IND = Indonesia; LAO = Laos; MAL = Malaysia; PHI = Philippines; THA = Thailand; VIE = Vietnam In the case of fibre plants, active collection and conservation of genetic resources is limited to the economically most important crops. China Like jute fibre it is also a bast fiber. Natural fibres possess a high strength to weight ratio, non-corrosive nature, high fracture toughness, renewability, and sustainability, … Host resistance to diseases and pests may assume the highest priority in breeding, when these have become a threat to the profitability or even survival of the crop (Simmonds, 1979). kenaf Cotton Development Authority (CODA), Pasig City: cotton (all aspects). CSIRO, Australia Thus, the major textile fibres found today have all been in use for a very long time. cordage, Gossypium barbadense clones (suckers, bulbils) Ryszard Kozlowski Poland. The end uses of fibre plants have been grouped in various ways, also depending on the definition of fibre plants applied (Hill, 1952; Kirby, 1963; Kochhar, 1986; Lewington, 1990; Schery, 1972; Simpson & Conner Ogorzaly, 1995). Flax, hemp, jute, and ramie are bast fibres, occurring in the inner bast tissue of certain plant stems and made up of overlapping cells. Plant fibres have been used for many years to make fabric and rope and are actually the exposed vascular bundles of the plant. Flax 40-400, Kapok <1 90 Less stringent pollution requirements from governments, in an attempt to promote investment in domestic paper manufacture. Rayon, Cellulose Wadding and Alginate fibres), are also frequently used in wound management and surgical dressings. stem, Phragmites vallatoria Table 6 presents the chemical properties of selected plant fibres. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. PROTA 16, 2005. It is generally cultivated in cooler regions of the world. In the plants, the fibres are situated in bundles at the periphery of the stem, hence the name ‘bast fibres’. 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). Genetic resources for Linum usitatissimum (flax and linseed) totalling more than 3000 accessions, representing mostly landraces and cultivars, are conserved in genebanks of many countries including France (Institut National de la Recherche Agronomique (INRA), Versailles), the Netherlands (Centre for Genetic Resources (CGN), Wageningen), Germany (Bundesforschungsanstalt für Landwirtschaft (FAL), Braunschweig; Genebank, Institute for Plant Genetics and Crop Plant Research (IPK), Gatersleben), the Russian Federation (N.I. This is usually done in the spinning mill prior to the spinning operation. Annual production and trade of the most important fibre crops (except woods for paper making) in the period 1996-2000 in the world. sisal division, suckers, leaf cuttings, seed, in vitro culture. Natural fibers possess several advantages over synthetic fibers such as low density, appropriate stiffness and mechanical properties and also high disposability and renewability. sacking, cordage, paper, Linum usitatissimum IAC, Brazil Fibres to be used for textile production are often subjected to additional chemical treatment to remove these compounds. (5-)20-25(-55) & D.A. In cases where conventional breeding methods are difficult to use, breeding programmes should be complemented with research and development on a range of biotechnological techniques. Section 4 presents the pulp and pulping process. When hydrolysed, the hemicelluloses from hardwoods release products high in xylose, whereas the hemicelluloses contained in softwoods yield more hexoses. For many thousand years, the usage of fibre was limited by natural fibres such as flax, cotton, silk, wool and plant fibres for different applications. Often bundles of harvested material are left for some days in the field to accelerate defoliation and desiccation. Sisal The brush fibres include African piassava (from Raphia hookeri G. Mann & H. Wendl. Apart from these parts of plants, we get plant fibers from grass, wood etc. 65 perennial herb 20-50 2.6.1 Introduction. sunn hemp flax n.a. A fibre sample from the pocket of the bag for slingstones,1886.1.1535.1, from New Caledonia was identified as Hibiscus tiliaceus, fau (Figure 26). 2.0-2.5 The production of the artificial fibre rayon requires highly purified cellulose as raw material. Fibres have long been spun into yarns that were woven or knitted into fabrics for clothing. Hemicelluloses consist of short, highly branched chains of sugars. INTRODUCTION Cellulose is a skeletal polysaccharide, ubiquitous in the plant kingdom and one of the commonest naturally occurring fibrous materials. Albizia falcataria (L.) Fosb.) THA Particle board is manufactured by hot-pressing pre-formed mattresses consisting of fibrous particles blended with resin and wax. Chinese mat grass Arundo donax L., for example, grows at average annual temperatures between 9 and 29 °C and an annual rainfall of 300-4000 mm. Jute fibers are bast fibers. 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. Examples – jute, flax, hemp etc. thatching, weaving, Cannabis sativa Artificial fibres, prepared by processing or regenerating some tissue elements of plants such as wood cellulose (e.g. Kapok has a length:width ratio of about 1000, but the fibre cells are normally too smooth to be spun into yarns, and thus not suitable for the production of textiles. perennial herb are examples of natural fibres or plant fibres. Cotton alone accounts for 25% of the world use of insecticides and Bt-cotton has proven to be a most effective way of reducing pesticide use, particularly because host resistance to bollworms and other important insect pests have not been detected so far in cotton germplasm.
