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. They include most commercial textile fibres and many local fibres such as Colona javanica (Blume) Burret, Curculigo spp. The main non-wood sources of paper are Gramineae (bamboos, cereal straw). India Vavilov Research Institute of Plant Industry, St Petersburg), United States (United States Department of Agriculture (USDA), Beltsville), Canada (Plant Gene Resources of Canada (PGRC), Saskatoon), India (National Bureau of Plant Genetic Resources (NBPGR), Akola Regional Station), China (Institute of Crop Germplasm Resources, Chinese Academy of Agricultural Sciences (CAAS), Beijing), Australia, eastern European countries and Argentina (Fu et al., 2002; IPGRI, no date; Marshall, 1989). Both recycling and plantation forestry can be expected to lead to increases in the cost of pulp, which in turn is expected to increase the competitiveness of non-wood fibre plants as a source of pulp and paper (Wood, 1997). Four samples were taken of the dark and lighter coloured cords made from plant fibres used for stringing the teeth of object 1886.1.1586 from New Zealand. In Germany, for instance, the use of plant fibres in the automotive industry grew from 4000 t in 1996 to about 14 000 t in 1999. toddy palm ), 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. sago palm Examples – jute, flax, hemp etc. The plants yielding seed or fruit fibres are 4 species yielding seed fibres and 1 species yielding fruit fibres. 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). lemba self-pollinating (88-99%) Cantala also prefers semi-arid conditions, though it can be grown in higher rainfall areas as well. annual herb Common plant spacings and densities for selected fibre crops. When the flower is fecundated it loses its petals and within 25 days a capsule surrounded by a leaf called bract grows. Ribboning machines are used for green stem material, in which the bark separates easily from the stem. Excessive processing, whether microbial, chemical or mechanical, results in degradation of the cellulose fibrils and a decrease in fibre quality (McDougall et al., 1993). These fibre crops are very high in its length, width, tenacity, uniformity, spinning pliability and flexibility. The processes rely on the action of one or more radicals acting on the lignin compounds. Material for thatching is often obtained from Gramineae (Imperata spp., Miscanthus spp. Often hardwood and softwood pulps are blended to make a particular product (Hague, 1997). Scientific name Fibres and fibrous material are obtained from various plant parts, mainly from the stems, leaves and fruits or seeds. It is used in making doormats, brushes, mattresses, packaging, bedding and flooring. 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). Rice straw is used in rice-growing areas such as Bali (Indonesia). Fibres are first spun into thread or yarn and then woven or knitted into fabrics. Some fibre plants tolerate a wide range of ecological conditions. Therefore, non-chlorinated bleaching agents, producing less toxic waste, are very much in demand nowadays. The size of operation also has an impact on the chemical recovery problem. Polyester Plant manufacturing operations are staggered in three production lines located within the same premises, at 38th K.M. Friday // 2.4.2011. Test. abaca Cultural methods may be sufficient in small-scale agriculture, but they are often uneconomic in large-scale industrial plantations. Albizia falcataria (L.) Fosb.) e.g. Many kinds of cordage exist, including rope, twine, binder twine and fish lines. Supply problems. fishing nets, Fimbristylis umbellaris pith, Bombacaceae Section 4 presents the pulp and pulping process. Crop residues left after the primary product has been harvested or extracted. thatching, cordage, weaving. 89 tying, weaving, Sansevieria roxburghiana However, some "pectins" have only 20% galacturonic acid and 80% neutral sugar residues, which is one of the reasons for combining them with hemicelluloses in the non cellulosic polysaccharides. However, apart from woody species for paper making, only a few of them, such as cotton, abaca, jute, kenaf, roselle, sisal and Wikstroemia spp. annual or perennial (under)shrub or tree United Kingdom, Cotton (lint) Table 11. jute, Tensile strength of fibre strands These plant fibers we get from the seeds of the plants. Predominant mating system 0.5 PLAY. The collection, conservation and characterization of germplasm has developed into a highly specialized activity carried out in genebanks established by national and international agricultural research organizations (FAO, 1996). 40-130, Ramie (10-)12-25(-44) Indonesia (1.2-)1.9-3.1(-6.3) ex Vent.). sacking, cordage, Corchorus olitorius The strands are twisted in the opposite direction to the yarns to form a rope. Medium density fibreboard (MDF) is manufactured by defiberizing softened wood chips at elevated temperatures (170 °C) using disc refiners, blending the resulting fibres with resin and wax, followed by drying, mattress forming and hot-pressing. perennial herb Fibres in general are defined as "slender strands of natural or man-made material usually having a length of at least 100 times their diameter and characterized by flexibility, cohesiveness and strength" (Lipton, 1995). Outside plant cabling can be installed by. Fertilizer recommendations depend on soil characteristics and nutrient uptake of the fibre crop. 2.1 Essential properties ; 2.2 Other important properties ; cotton-m3. In the manufacture of rope, lengths of fibre are spun into yarns, which are twisted together into strands. the outer surface is covered with a protective wax like coating which gives fibre an adhesive quality. 659 p. Choix des espèces . It involves crushing the plant material and scraping the non-fibrous material from the fibres. Netherlands 18 684 vol. It is naturally smooth and straight. Forms include groundwood, lacebark, thermomechanical pulp (TMP), and bleached or unbleached kraft or sulfite pulps. Table 13. In this process, the leaves are trimmed to remove the spines and subsequently passed through decorticating machines that crush them between rollers and scrape them against a bladed drum. brushes, thatching, stem, Lepironia articulata 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. malvacearum) on cotton. By using our services, you agree to our use of cookies. liana Fibre can be of two types. in association with other tissues. cattail Examples – cotton, kapok etc. Created by. The preferred propagation methods for perennial fibre plants are mostly vegetative, for example using rhizome cuttings (ramie), suckers (cantala), bulbils (sisal, Furcraea foetida) and corms (abaca). Fibers are natural or man-made such as cotton, silk, jute, etc. Molecular marker technology is applied in many crops for germplasm characterization and management, accelerating gene introgression from related species and for marker-assisted selection (MAS). Indonesian Tobacco and Fibre Crops Research Institute, Malang: various aspects (agronomy, breeding, ecophysiology, plant protection), mainly of cotton, but also of jute, kapok, kenaf, ramie and roselle. ricepaper, Typha domingensis Because there is no such system, many genomic, proteomic, and metabolomic studies of fiber development result in data representing averaged developmental stages and cell types that were pooled together. It is also known as coconut cotton. Adequate spacing between plants is required to allow for weeding and harvesting. Abaca, on the other hand, needs 2000-3000 mm of rainfall per year. It is used in the twine, rope, bags, doormats etc. Sansevieria roxburghiana parasitica) on kenaf and roselle, Fusarium wilt on cotton, abaca, kenaf and roselle, and Verticillium wilt on cotton. INTRODUCTION History of fibres is as old as human civilization. The plants yielding leaf fibres include 18 species of which the entire leaf or leaf strips are used, and 13 of which leaf fibres are separated. The present volume follows the commodity grouping adopted for the Prosea Handbook as presented in Jansen et al. Cotton, however, may be grown under irrigated or rainfed conditions. <1 perennial herb In general the most important textile and cordage fibre-yielding families are the Malvaceae (cotton, kenaf, roselle) and Tiliaceae (jute). These have already led to the release of GM cultivars with resistance to herbicides in Canada (Trouvé, 1996). perennial herb 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). RUSSIAN JOURNAL OF PLANT PHYSIOLOGY Vol. Plantes à fibres. PROTA 16, 2005. Actinoscirpus grossus Portugal The weedy behaviour of many species such as, Unwanted morphological characters of species, such as the irritating hairs of. Annual production and trade of the most important fibre crops (except woods for paper making) in the period 1996-2000 in the world. Ibrahim Group is one of the leading business groups in Pakistan with businesses spanning over Textile, Banking & Energy. Length Softwood fibres became dominant with the advent of the sulphite pulping process, developed in 1857 (McDougall et al., 1993; Simpson & Conner Ogorzaly, 1995). Molecular fingerprinting is also applied here to establish genetic diversity in flax and linseed germplasm (Fu et al., 2002). éd. This usually requires the simultaneous selection for plant type and vigour, ecological adaptation, yield, quality and other characters. Lower product quality and more difficult processing techniques needed for them, thereby increasing production costs. textile, Gossypium herbaceum stem, Scirpodendron ghaeri 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. After the fabric is formed, it is ... detailed classification of fibres is as shown in Figure 6. Chinese mat grass Romania For these products fibres must be strong and stiff, but also flexible. Fibres to be used for textile production are often subjected to additional chemical treatment to remove these compounds. cross-pollinating (8-)19-22(-35) perennial grass Fibre Industry Development Authority (FIDA), Department of Agriculture (DA), Quezon City: all aspects: propagation, production, utilization, etc. They are usually included in the "jute-like fibres", a group also including China jute (Abutilon theophrasti Medik., synonym: A. avicennae Gaertn. round-leaf salago Heliconia indica leaf fibre, leaf, Curculigo latifolia stem, Schoenoplectus lacustris Mauritius hemp (10-)20-25(-60) 90 The general objective of plant breeding is the development of cultivars with the potential to provide maximum economic benefits to the growers. NARC, Philippines width Australia If the technical problems of chemical recovery in non-wood pulping are solved along the lines of today's pulping process technology, the size and cost of chemical recovery, effluent treatment and other control measures will increase, which will reduce much of the financial advantage non-wood fibre pulping has had in some regions. Tanzania Fibres, are defined by the Textile Institute as units of matter characterized by flexibility, fineness and a high ratio of length to thickness (refer to Textile Terms and Definitions). 1494 leaf fibre, Gramineae They are widely used in South-East Asia, despite the growing popularity of zinc roofs. Examples – coir from hard shell of coconuts. and packing. University Putra Malaysia (UPM), Serdang: utilization of kenaf for composite products. Sometimes whole twigs, fine stems or roots are utilized; fibres are also obtained from leaf stalks of palms. 65 As the leaf emergence rate depends on ecological conditions (mainly temperature and rainfall) the lifespan of a sisal plant may vary from 3 to 20 years. First of all, any fiber produced by plants, animals and geological processes is considered natural fibers. The principal business is manufacture and sale of polyester staple fibre and yarn. The bark ribbons may subsequently be retted in the usual way (Wood, 1997). cordage, barkcloth, Boehmeria nivea 270-400 × 75-100 (double rows; Lower yields, partly because of the lack of research and development work on lesser-known species. 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. However, bagasse is also an important source of fuel for boilers of sugar mills, and for that reason in short supply for alternative applications (Moore, 1996). The primary structure of all celluloses is a β-1,4-linked polymer of D-glucopyranose residues (Figure 1). Many of those that are harvested for leaf fibres are monocarpic: they flower only once after a certain number of leaves have formed, and die after flowering. China (12-)18-28(-38) Taxonomic and morphological data on the major fibre plants treated in this volume. Table 12 presents an overview of genebanks with germplasm collections of 9 major fibre crops. These fibres may then be reorganized as paper or they may be further treated with chemicals. Irrigation of fibre crops in industrial plantations occurs in Indonesia for roselle, but most fibre plants are planted at the onset of the rainy season and grown under rainfed conditions. (mm) 57 No. cotton and kapok. thatching, weaving, Curculigo capitulata leaf, Cyperaceae It is a process during which seeds are pulled free from the fibres covering them, in the case of cotton followed by extensive further cleaning and combing of the fibres (Simpson & Conner Ogorzaly, 1995). annual or perennial shrub An overview of the 72 major fibre plants is presented in Table 1. division, seed, in vitro culture, Sansevieria spp. It is used to make rope, shoes, food paper, bioplastics, biofuel etc. Work is in progress to develop wide-spectrum insect resistance based on a combination of several Bt and proteinase-inhibitor genes (Hau, 1999). bast fibre, Typhaceae thatching, weaving, brooms, Raphia farinifera tying, weaving, Raphia vinifera Aerial suspension Wet decorticated fibre is usually washed before being dried. Environmental and ecological factors restricting massive production: some species are suited only for a specific region with specific environmental conditions. 100-150, Sugar-cane bagasse Many types of linkages between the monomers have been found, but the β-O-4 aryl ether is the most common. Various sources. and Myrtaceae (Eucalyptus spp.). Hylander, R. hookeri and R. vinifera P. Beauv. bast fibre, Anodendron oblongifolium stem, Miscanthus sinensis This paper highlights the physical and chemical surface modifications of plant fibre (PF) for attaining suitable properties as reinforcements in cementitious composites. As the breaking load depends on the cross-sectional area of the fibre, a more useful characteristic is the tensile strength: the breaking load or force per unit area of cross-section, usually expressed in N/mm2 (106 Pa) or in kg/mm2. Separate statistics for kenaf and roselle are not available. seed, suckers, rhizomes, Corchorus spp. Substitution of established products by those from lesser-known species; e.g. ), for example on cotton and kenaf. and Para piassava (from Leopoldinia piassaba Wallace). It is especially important in plants with little competitive ability (e.g. Thailand, Ramie cordage, mats, brushes, thatching, weaving, Crotalaria juncea It is also a seed fiber like cotton fiber. China produces about half of the world's non-wood pulp (Croon, 1995; Wood, 1997). Environmental concern has resulted in a renewed interest in bio-based materials. The perennial fibre crops sisal, ramie and abaca are cross-pollinating species. flax The major South-East Asian fibre plants treated in Chapter 2 comprise 72 species belonging to 25 plant families. Various sources. 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. 11. The material is then passed through a "scutching" machine, which removes the shiv from the fibre by beating and scraping. Artocarpus elasticus weaving, Furcraea foetida Important pests include various bollworms on cotton, the jassid leaf hopper (Amrasca biguttula) on roselle, and the Mexican sisal weevil (Scyphophorus interstitialis) on sisal. It is thus a ligno -cellulosic fibre that is partially a textile fibre and partially wood. 3.1 The cellulosic fibers ; 3.2 The polymer system of cotton; bast fibers-m4. 200-250 × 80-100 (single rows) This introductory lecture is meant to bring the class to a common wavelength so future understanding of the course is built on coherent concepts. The breeding methods commonly applied include line and pedigree selection - starting from landraces, older cultivars, or segregating progenies after crossing and backcrossing - all leading to uniform, homozygous cultivars. Thus, the major textile fibres found today have all been in use for a very long time. 371 Mauritius hemp stem, leaf, Urticaceae Table 5. A range of mechanical processes have been developed involving chemical pretreatment (mostly with sodium sulphite), either alone or in combination with a temperature pretreatment. perennial grass flax The stiff competition offered by fibre crop producing countries outside South-East Asia limits the scope for industrial plantations in the region. bast fibre. 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). Cotton is notoriously sensitive to pests, which has led to excessive spraying of insecticides. 40-130, Sisal Scientific name Nylon, Rayon, Polyester etc. perennial herb Diseases and pests of fibre crops in South-East Asia include fungi, bacteria, viruses, nematodes, insects and parasitic plants. The brush fibres include African piassava (from Raphia hookeri G. Mann & H. Wendl. Bt-cotton was first released in Indonesia in 2001 and India is likely to follow soon (James, 2001). Plant fibres consist of primary and secondary cell walls (Figure 1). Table 1. Annual bast fibre plants such as jute, kenaf, roselle and flax are usually not allowed to complete their life cycle, because the fibres are located in the vegetative parts, and optimum fibre quality is obtained by harvesting immature plants. Most chemical pretreatments do not affect pulp yields, but only soften the chips prior to fibre separation. 1000-2000, Hemp Crop sucker shoots, stem cuttings, seed, Phragmites vallatoria These plant fibers are collected from leaves of the plants. In perennial fibre crops such as sisal the leaves are also cut manually. Cell wall thickness and lumen diameter are generally less important (McDougall et al., 1993). Examples are cotton, jute, wool, and silk. Softwood fibres are ideal for paper making, because their long, thin, flexible structure allows them to pack closely together into non-porous, tightly bonded sheets. Type of plant Plants used for basketry are primarily found in the Cyperaceae, Gramineae, Palmae and Pandanaceae. It is used in numerous fields in various ways. Sorry!, This page is not available for now to bookmark. textile, paper, Miscanthus floridulus Following the introduction, a review of the studied fibres including plant description, chemical and morphological characterizations of vegetable fibres are presented in Section 2. Natural fibres conduct heat, can be properly dyed, resist mildew, have natural antibacterial properties, block UV radiation and can be easily made flame retardant. Introduction. 34 and Enhalus acoroides (L.f.) Royle in South-East Asia. In a break-in, fibers ... Plant fibers, such as cotton, may be more ribbon shaped and may contain twists at irregular . After the end of the growing season, the plants are harvested (Fig. Life cycle, mating system and multiplication of selected fibre crops. Ibrahim Fibres Limited is an industrial company in Pakistan having diversified business activities including Polyester Yarn production, Polyester Staple Fiber production, Financial Services and Energy. 4.1 Jute ; 4.2 Fibre Composition and Morphology ; 4.3 Properties of Jute Fibre seed (lines), self-pollinating (95-100%) self-pollinating (97-100%) stem, Fimbristylis umbellaris & D.A. Table 3 presents statistics on the production and trade of the most important fibre crops (excluding woods for paper making) from 1996 to 2000. The length:width ratio is important, because it affects the paper's flexibility and resistance to rupture. This difference in chemical composition affects properties such as the resistance to washing in hot water and the acceptance of dyes. Where wood-based fibres dominate, non-wood fibres usually only occupy small niche markets providing specialist properties to a range of high added-value products. 20-30 × 5-10 Particle board is manufactured by hot-pressing pre-formed mattresses consisting of fibrous particles blended with resin and wax. Table 8. white jute Yeah! Wood chips are initially cooked in a digester, and then defibrated with disc refiners. These plant fibers are collected from the inner bark or blast of plants. Cotton, flax and ramie generally have a length:width ratio of 1000 or higher. Sisal 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). Annual bast fibre plants are usually harvested manually, by cutting or pulling. This page was last modified on 29 April 2016, at 11:32. Long strands of molecules interwoven to form a linear, string-like structure are known as ‘Fibres’. Cotton Development Authority (CODA), Pasig City: cotton (all aspects). perennial herb Width An overview of important fibre plants with other primary use is presented in Table 2. The inner stem and outer gets separated and the outer plant gets individualized to form fibers. We get cotton fiber from the seeds of plants. Flax was probably first cultivated before 1000 BC, and linen from flax was used by the ancient Egyptians, Greeks and Romans. broadcast Andamanese bowstring plant Families with the greatest number of species are the Cyperaceae (11 species), Malvaceae (10 species), Palmae and Pandanaceae (5 species each), Tiliaceae, Gramineae, and Thymelaeaceae (4 species each) and Agavaceae (3 species) (Table 9). When fibre plants are defined in a broad sense, by far the most important fibre plants on a world scale are woody species used for paper making, with an estimated annual production in the early 1990s of about 1750 million t (Bolton, 1995). We get jute fibers from the stem of jute plants. 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. division, suckers, seed, in vitro culture, Juncus effusus fruit fibre, Cyclanthaceae Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Wikstroemia indica These characteristics usually vary widely within species, even between fibre strands within the same plant. These fibres have higher tensile strength than other fibres. Russian Federation Other potential uses include geotextiles for erosion control on slopes and for agricultural mulching. Processes with biological pretreatments (biomechanical pulping) are mainly based on the use of fast-growing lignin-degrading white rot fungi (Phanerochaete chrysosporium and Phlebia tremellosa). 0 abaca, hemp, jute, kenaf, New Zealand flax (, Bast fibres ("soft fibres"): the soft and flexible fibres extending through the inner bark ("bast") of stems of dicotyledonous plants. 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. shrub-tree Lower capital investment requirements for non-wood pulp and paper mills, due to smaller size and fewer technical problems. Difficult chemical recovery. "Natural Fibers: Many different natural fibers originating from plants and animals are used in the production of fabric.Cotton fibers are the plant fibers most commonly used in textile materials, with the type of cotton, fiber length, and degree of twist contributing to the diversity of these fibers. 7873 The principal organizations and institutes conducting research and development on fibre plants in South-East Asia are the following: In South-East Asia, as in the rest of the world, many plants are available that produce fibres suitable for various end uses. The explanation for the popularity of wood is its low cost and high fibre quality. Flax, on the other hand, is a long-day plant. In addition, plant fibres were widely used for making rope, twine and fishing nets. Abroma augusta China MAL Forest Products Research and Development Institute (FPRDI), Department of Science and Technology (DOST), College, Laguna: research and development on fibre crops for pulp and paper, composite boards, furniture and handicrafts. Phormium tenax Smaller quantities of hardwood are also used, especially for particle board, but generally not preferred, because the higher dust levels associated with their processing can increase resin consumption and processing costs, and can increase the risk of fire and explosion in the factory (Hague, 1997). 10-40(-64) The fibres of these plants are uniform on the surface and the cell tips, and the fibre cells have an intermediate length:width ratio. 132 Many fibre plants, especially those with small seeds, are broadcast directly in the previously prepared field, but other crops are raised first in nursery seedbeds before being planted out. Hibiscus tiliaceus L.) in Prosea 5 (Timber trees), toddy palm (Borassus flabellifer L.), sago palm (Metroxylon sagu Rottboell) and nipa palm (Nypa fruticans Wurmb) in Prosea 9 (Plants yielding non-seed carbohydrates), hemp (Cannabis sativa L.) in Prosea 12 (Medicinal and poisonous plants), and coir (Cocos nucifera L.) in Prosea 14 (Vegetable oils and fats). Jute is the most important fibre for coarse fabrics for sacking. IMCs find application in plaster boards, tiles, concrete, mortars and plasters. The variation in photoperiod-sensitivity among cultivars can be exploited by choosing sowing dates and cultivars in such a way that the duration of the vegetative period and yield are optimal. % of world. CGN, Netherlands seed fibre, Gossypium herbaceum 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). The polymerized pentoses are called pentosans. Philippines tree Spain perennial herb Day length influences growth and development of several fibre plants, indirectly affecting growth and yield. Molecular fingerprinting has contributed considerably to a better understanding of the genetic and genomic relationships between cotton varieties and species (Abdalla et al., 2001). Machines of this type have been developed for kenaf in the United States. Artificial fibres such as viscose, acetate and tri-acetate are obtained from cellulose contained in living plants.
