IAC, Brazil Flax, on the other hand, is a long-day plant. Propagation methods of the major fibre plants treated in this volume. Hemicelluloses are soluble in 18.5% NaOH and this is the basis for their measurement in TAPPI test methods (Biermann, 1993). Both softwoods and hardwoods are used in a wide range of papers. cordage, nets, paper, Cocos nucifera New Zealand flax Tetrapanax papyriferus Decortication is used primarily for hard leaf fibres such as sisal, cantala and henequen. stem, Hemerocallidaceae Softwoods yield tracheids and xylem fibres, and hardwoods produce a mixture of tracheids, vessel elements and xylem fibres. 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. IBF CAAS, China perennial herb Cotton is notoriously sensitive to pests, which has led to excessive spraying of insecticides. 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. Outside plant cabling can be installed by. Japan. These essentially mechanically based processes are often difficult to distinguish from semi-chemical processes (Moore, 1996). (1.2-)1.9-3.1(-6.3) 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). Fibres in general are defined as "slender strands of natural or man-made material... Role of fibre plants. bacterial blight and, Jute: early crop maturity and low photoperiod-sensitivity, finer and whiter fibre quality, resistance to diseases (. sisal in association with other tissues. The yarns running the length of the fabric are termed warp (or warp yarns), whereas the crosswise yarns are called filling or weft (or weft yarns) (Smith, 1995). white jute Some annual plants have a low fibre content. thatching, weaving, Curculigo capitulata cordage, paper, Hibiscus cannabinus The fibre strands of commerce usually consist of bundles of individual sclerenchyma fibre cells, the exception being ramie, where commercial fibres are single fibre cells. ratio, Abaca sampora Table 3. In this video of Fibre to Fabric, we will understand the beautiful science behind the process of making Fibres and turning them into Fabrics. 1000-2000, Hemp bast fibre, Typhaceae Hemicelluloses (%) This was probably Juncus effusus 1 INTRODUCTION. The plants yielding stem fibres include 23 species yielding bast material, 20 species of which entire or split stems are used, and 1 species of which the pith of the stems is used. Pakistan Dimensions of the ultimate fibres of selected fibre plants. India Lignification increases the rigidity of the cell wall, makes it less susceptible to predation and less permeable to water (McDougall et al., 1993). 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. Philippine Textile Research Institute (PTRI), Department of Science and Technology (DOST) Complex, Bicutan, Taguig, Metro Manila: production and processing of fibre crops for textiles. textile, paper, Miscanthus floridulus kenaf Russian Federation Belarus perennial herb e.g. The processes differ in their nature and the pulp yield obtained. China, Jute-like fibres1 Thus, the major textile fibres found today have all been in use for a very long time. 510-635 are examples of natural fibres or plant fibres. perennial herb 10-40(-64) weaving, tying, Tetrapanax papyriferus This genebank holds seed samples of some 9000 accessions, including about 4600 of Gossypium hirsutum L., 2500 of G. arboreum L., 1200 of G. barbadense L., 200 of G. herbaceum L. and various numbers of accessions of a further 37 Gossypium spp. Romania, Jute Thailand MAL 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. Work is in progress to develop wide-spectrum insect resistance based on a combination of several Bt and proteinase-inhibitor genes (Hau, 1999). 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. Straw remained a major source of fibre in Europe and North America until the wood-based industry became fully established during the latter part of the 19th century (Moore, 1996). ), Palmae (Borassus flabellifer, Cocos nucifera, Corypha utan Lamk, Eugeissona triste, Nypa fruticans) and Pandanaceae (Pandanus spp.). 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. Forest Research Institute Malaysia (FRIM), Kepong: utilization of kenaf for pulp and paper and composite products. Typha domingensis 132 Most textile and cordage fibre plants, including abaca, cantala, kenaf, ramie, roselle and sisal, need well-drained soils, as they do not tolerate waterlogging, but white jute (Corchorus capsularis L.) is relatively tolerant to inundation in later development stages. stem, Lepironia articulata 3-4 The pulping methods can be divided into three main processes: chemical, mechanical and semi-chemical. Andamanese bowstring plant Introduction. Write. 20 In grasses, nodes are often unwanted and need to be separated out. List of Plant Fibers Here we are describing some common plant fibers with their uses – Jute Fiber - Jute fibers are bast fibers. Most fibre plants treated in this volume are not frost-hardy, but mature P. tenax is tolerant to frost and T. papyriferus may also survive light frost. The fibre cells of ramie are the longest of all the vegetable fibres, followed by cotton, flax and hemp. The production of the artificial fibre rayon requires highly purified cellulose as raw material. Crop rotation and the use of organic fertilizers may also be applied to maintain soil fertility. Wool became the main fibre for clothing in western and southern Europe, and hemp in northern Europe. INTRODUCTION Fibres are thread like materials which can be used for different purposes. Rationale Plants are universally recognized as a vital component of the world's biological diversity and an essential resource for the planet. 250-350, Cotton are few examples of Synthetic Fibers. 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. Table 11 presents an overview of commonly applied plant spacings and densities for the most important fibre crops. tree These fibers are also 2-3times stronger than cotton fibers. Some other fibre crops have desirable qualities for burlap bags. 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). Many plants used for weaving, on the other hand, grow in swampy or inundated locations: Donax canniformis, Juncus effusus, Phragmites vallatoria (Pluk. leaf, Musa textilis Mauritius hemp, Durability Crop residues left after the primary product has been harvested or extracted. leaf, leaf fibre, Pandanaceae Examples are oxygenated agents such as O2/OH-, H2O2 and O3. Molecular fingerprinting has contributed considerably to a better understanding of the genetic and genomic relationships between cotton varieties and species (Abdalla et al., 2001). ex Blume and Antiaris toxicaria Lesch. Fibre hemp, flax, Juncus effusus, Miscanthus spp., Phormium tenax and Tetrapanax papyriferus (Hook.) Mauritius hemp Other important collections, Abaca Pro Lite, Vedantu Cycas leaflet). 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. Aerial suspension lemba Department of Agriculture: research and development on cotton, jute and jute like fibre, kenaf; technology transfer to extensionists, farmers and companies. The fibres of these plants are uniform on the surface and the cell tips, and the fibre cells have an intermediate length:width ratio. 14 For these products fibres must be strong and stiff, but also flexible. annual herb Often bundles of harvested material are left for some days in the field to accelerate defoliation and desiccation. For a long time, cotton was the only source of the cellulose used in the production of artificial fibres and other cellulose products. Sisal (×1000 ha) The fibre is subjected to a special combing operation ("hackling") prior to spinning (Simpson & Conner Ogorzaly, 1995; Wood, 1997). The xanthate groups are hydrolysed and the cellulose structure is re-established. In the manufacture of rope, lengths of fibre are spun into yarns, which are twisted together into strands. Those composed of cellulose and lignin are considered vegetable or plant fibers. Development of germplasm collections for lesser-known species (cultivated or wild-harvested) with high potential. 1. Cotton, however, may be grown under irrigated or rainfed conditions. Cell wall thickness and lumen diameter are generally less important (McDougall et al., 1993). Progress in crop improvement requires access to adequate resources of genetic variability. Eugeissona triste, or as by-products from homesteads or plantations, e.g. Eugeissona triste Griff.) weaving, Schoenoplectus mucronatus Perennials with intermediate annual requirements include kapok and Thespesia lampas (1500-1700 mm). Lack of timber resources in some countries with a large population and consequently a high demand for paper, such as China, India, Bangladesh, Pakistan and Iran. self-pollinating (88-99%) Estimated annual production (× 1000 t) of major fibre crops in South-East Asia in the period 1996-2000 (no information available for Papua New Guinea). Manmade fibers are called synthetic fibers. Product improvement, product diversification and waste utilization. (3.7-)7-8(-12) To have a source of fiber to utilize in production, the fiber first must be extracted from the plant. 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). (9-)15-20(-33) 0 Heliconia indica Lamk). Crop Length Cookies help us deliver our services. Bt-cotton was first released in Indonesia in 2001 and India is likely to follow soon (James, 2001). annual herb stem, Raphia farinifera Sansevieria roxburghiana Rooting is easily stimulated by application of growth regulators. Plants used for making baskets, mats and wickerwork (including brooms). Table 7. (6-)13-29(-53) coir perennial herb The polymerized pentoses are called pentosans. Polyester Plant manufacturing operations are staggered in three production lines located within the same premises, at 38th K.M. ), Congo jute (Urena lobata L.), other Malvaceae, and sunn hemp (Crotalaria juncea L.). Sri Lanka paper mulberry United States INTRODUCTION Fibres are thread like materials which can be used for different purposes. Control of diseases and pests includes cultural, chemical and biological methods. The elasticity is the degree to which the fibre recovers its original length after extension. fishing nets, Fimbristylis umbellaris cellulose plus hemicelluloses, whereas α-cellulose is the fraction isolated by a caustic extraction procedure. Tanzania (×1000 t) Fibers fall into two broad categories: natural and man-made (or synthetic). 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. Lignin Development of improved cropping practices and processing methods. Abroma augusta USDA/ARS, United States Small amounts of wax are added to boards to improve their short-term resistance to thickness swelling in damp or wet environments (Hague, 1997). Another useful characteristic is the elongation at break, which is a measure of the resistance of material to elongation. textile, cordage, fishing gear, Broussonetia papyrifera The largest potential market for non-wood plant fibres is that of paper and paperboard; even a small percentage deficit in supply of wood fibre would create huge opportunities for non-wood plant fibres (Bolton, 1995). Hardwoods are commonly pulped using the NSSC process, with the pulps particularly suitable for use in packaging grades of paper, e.g. India Natural plant stems/ stalks/ leaves fibers have been in use extensively in fast decade for production of Handicraft, Ropes etc. 0 Netherlands Many pulping processes have been developed to convert raw materials into separated fibres suitable for use in paper making. seed (lines), self-pollinating (95-100%) Such information will facilitate more efficient utilization of cotton genetic resources in the future. This genebank stores and maintains about 6000 accessions, including some 4000 for jute alone (Corchorus capsularis, C. olitorius L. and other Corchorus spp.). India 0.5 ), caulking (seams between planks, barrels etc.) BUR1 Read more about seed fibres. Fibres produced by plants (vegetable, leaves and wood), animals and geological processes are known as natural fibres. African bowstring hemp Most chemical pretreatments do not affect pulp yields, but only soften the chips prior to fibre separation. A material which is composed of thin and continuous strands is known as fibre. At present, the only mass-propagation of fibre plants through in vitro culture in South-East Asia is with abaca in the Philippines, where tissue-cultured plants are used in replanting programmes. Pandanus atrocarpus sacking, cordage, Corchorus olitorius (mm) Examples – cotton, kapok etc. stem, Schoenoplectus litoralis bast fibre Bast fibre , soft, woody fibre obtained from stems of dicotyledonous plants (flowering plants with net-veined leaves) and used for textiles and cordage. For industrial fibres, e.g. annual or were long made into binder twine for the tying of hay bales, but they have now been largely replaced by synthetic fibres (Wood, 1997). division, rhizomes, seed, in vitro culture, Miscanthus spp. Common name Spain, Coir Donax canniformis (G. Forster) K. Schumann, Fimbristylis umbellaris (Lamk) Vahl), thatching (e.g. cordage, textiles, Wikstroemia indica In the case of fibre plants, active collection and conservation of genetic resources is limited to the economically most important crops. It is one of the most affordable fibers. Ressources végétales de l'Afrique tropicale. 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 time of harvest for annual bast fibre plants such as jute, flax, kenaf and roselle involves a trade-off between fibre yield and quality, and these plants are usually harvested at a specific developmental stage. 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. 20-30 × 5-10 pith, Bombacaceae Life cycle, mating system and multiplication of selected fibre crops. Fibre Plants - seed, bast & hard fibres: Plant Fibre from cotton, linen, hemp & jute. (10-)25-60(-100) weaving, thatching, Typha orientalis Philippines (IPB), Cotton 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. In Table 5 the dimensions of selected plant fibres are presented. It needs to be replaced more often than zinc, but this also depends on species used and construction technique. tying, weaving, Raphia vinifera annual herb Taxonomic and morphological data on the major fibre plants treated in this volume. Institute for Research and Development of Cellulose Industries, Bandung. The strands are twisted in the opposite direction to the yarns to form a rope. 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). Flashcards. Crop perennial grass United Kingdom, Cotton (lint) 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. weaving, Anodendron candolleanum Table 10. Jute plant is cut and kept immersed in the water for Retting process during season. Scientific name Direct burial 3. China If the fibres are not sufficiently strong they will not be able to withstand such treatment and the strength of the final yarn will be unsatisfactory. 90-100 cm between rows of each pair) great bulrush (0.8-)1.2(-2.8) perennial herb Plant fibers can be mainly divided into following three types –. Rice straw is used in rice-growing areas such as Bali (Indonesia). Lesson 1: Introduction to Fiber Optics. Fiber evidence can be found at crime scenes in a number of different ways. Plant fibers are employed in the manufacture of paper and textile (cloth), and dietary fiber is an important component of human nutrition. Netherlands Ribboning machines are used for green stem material, in which the bark separates easily from the stem. The main processes are retting, scutching, chemical treatment, decorticating and ginning (Simpson & Conner Ogorzaly, 1995; Wood, 1997). They are most commonly associated with xylem and phloem. 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. Department of Agricultural Extension: development and transfer of the fibre plant production practices to farmers. annual or perennial shrub Most animals that produce textile fibers are mammals. Do you know from where we get that? Family The time from planting to first harvest ranges from a few months in annual herbs such as jute and kenaf to several years in perennials such as abaca and sisal. Thailand 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. 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). Bast fibres can also be extracted from green or dried stem material by mechanical means without being retted first. The uptake by 1 ha of Corchorus capsularis producing 2 t dry retted fibre is about 63 kg N, 14 kg P and 132 kg K (Dempsey, 1975). cordage, barkcloth, Boehmeria nivea Fibres that are obtained from plants or animals are called natural fibres. The term holocellulose refers to the entire carbohydrate fraction of the material, i.e. However, where wood-based fibres are not sufficiently available, non-wood fibres are used across the spectrum of paper and paperboard products (Moore, 1996). wild breadfruit Plant fibres are elongated most commonly sclerenchyma supportive plant cells with thick cellulose walls with a well-organised structure. Gravity. Crop Various sources. Various basic procedures are used to separate fibres from the surrounding plant tissues. and flax (Linum usitatissimum L.), and also lesser-known species used for weaving (e.g. Plant fibers are sclerenchymatous cells with heavily lignified cell walls having a narrow lumen in cross section. 1.1 Introduction; 1.2 Micro-structure of a textile fiber and filament ; essential properties of fiber forming polymers-m2. to include those plants from which fibres are extracted and used to make textiles, cordage, and sometimes also paper (Lipton, 1995; Wood, 1997). cordage, Schoenoplectus lacustris The treatment involves soaking the separated bark in weak alkali baths for a given period at a given temperature. bog bulrush Fibres from these plants can … Of these, CTMP, using a pretreatment with 1-4% sodium sulphite, has become the most widely used. stem, Phragmites vallatoria Russian Federation Multiplication, Cotton have reached the international market and persisted there. periuk kera Important fibre plants treated in other PROSEA volumes. This is usually done in the spinning mill prior to the spinning operation. Escobin & H.A.M. Cotton is a vegetable fiber obtained from the mature capsule of the cotton plant, a shrub about 40cm high, with leaves and flowers of a red and yellow colour. perennial herb Brazil, Philippines. perennial herb brushes, thatching, cordage, fishing gear, Anodendron paniculatum 250-1000, Jute For cordage, rough fibres are used in general, such as abaca and sisal. Fibres to be used for textile production are often subjected to additional chemical treatment to remove these compounds. Sugar-cane bagasse has been considered as a source of raw material in various Asian countries, including Thailand and India. 283 Mechanical pulping is mainly applied for softwoods such as spruce. 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). Tanzania All evidence indicates that cellulose is a homopolymer, not covalently bonded to other constituents of the cell wall. CAM broadcast perennial herb Rough cordage is obtained by simply twisting together bast ribbons, e.g. division, suckers, seed, in vitro culture, Juncus effusus CSIRO, Australia Other sources of barkcloth in South-East Asia include Artocarpus elasticus Reinw. The chemical processes separate the cellulose from the lignin, whereas the mechanical processes convert all the constituents present. Export Seed and fruit fibre plants such as cotton and kapok, on the other hand, are harvested after completion of a generative phase. Malaysia Cotton Development Authority (CODA), Pasig City: cotton (all aspects). A range of mechanical processes have been developed involving chemical pretreatment (mostly with sodium sulphite), either alone or in combination with a temperature pretreatment. 6-15 (between rows) This ‘Introduction’ describes the classification of natural fibres, levels of production and advantages derived from their excellent permeability, biodegradability and healthy properties. 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). Fertilizer recommendations depend on soil characteristics and nutrient uptake of the fibre crop. This difference in chemical composition affects properties such as the resistance to washing in hot water and the acceptance of dyes. Department of Industrial Promotion: technology transfer with respect to the production of handicrafts and cloth from fibre plants such as jute, cotton and paper mulberry; promotion of the production of handicrafts from fibre plants. Ryszard Kozlowski Poland. January 1970; DOI: 10.1007/978-3-642-04796-1_1. Alternatively, where non-wood pulp mills are based on agricultural residues or annual crops that are grown in scattered locations, they must be kept small to minimize transport costs, which means they cannot benefit fully from the economies of scale enjoyed by wood-based mills. The most valuable of all stuffing materials is kapok (Ceiba pentandra (L.) Gaertn. The ratio of the different constituents and the chemical nature of the lignin and hemicelluloses varies widely between plant types and species (McDougall et al., 1993; Moore, 1996). Fibre can be of two types. Adequate spacing between plants is required to allow for weeding and harvesting. have potential in the market for specialty papers. Miscanthus spp. Schultes & J.H. Pakistan 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). perennial herb It is stronger than fibers such as cotton. Ecuador 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. Tanzania 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. Cotton fibers are seed fibers. Japan Table 9. 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). Natural fibers possess several advantages over synthetic fibers such as low density, appropriate stiffness and mechanical properties and also high disposability and renewability. 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. 18 684 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. These plant fibers are collected from leaves of the plants. 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. Type of plant Fibres used for brushes normally have thick filaments, with orderly cells very compactly arranged in the fibre bundle, a low length:width ratio of fibre cells, and thick fibre walls. However, the available systems of cytoplasmic male sterility have been inadequate for large-scale production of hybrid seed, mainly due to incomplete expression of fertility restorer genes in the male parents. VIR, Russia 57 No. (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. It normally involves the immersion of bundles of stems in ponds or streams. (10-)19-20(-30) Main plant parts used, Agavaceae We get jute fibers from the stem of jute plants. 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 genes controlling the trait, resistance to diseases ( which means that repeating.
