Some examples are: aspen fibre, abaca fibre, bagasse fibres, bamboo fibre (BF), banana fibre, etc. These are elongated cells with tapering ends and very thick, usually heavily lignified cell walls. These structural differences are reflected on fibre properties, i.e. Fibres extracted from hop stems contain 84% of cellulose, 6% of lignin in 2% of ash. Flax is a plant from which linen fabric is obtained though a lot of processing goes into making the fibers and later fabric. The monoclinic unit cell has dimensions of 0.835 nm for the a – axis, 1.03 nm for the b-axis or fibre period, 0.79 nm for the c-axis, and 840 for the ß angle according to Meyer, Mark and Misch [Krässig 1992]. This effect was minor for wheat straw than flax straw. Jute is a long, soft and shiny fibre that can be spun into coarse, strong threads and is one of the cheapest natural fibres. by-products are utilized as agro-based biofibres [Reddy 2005]. The fibre bundles were mainly inhomogeneous and sclerenchyma cells were often accompanied by tracheary elements. The cuticle layer consists of wax and pectin materials. It has been recognized as a complete food due to its protein quality. using bacteria and fungi, chemical and mechanical methods. Light microscopy tests were performed on whole stems and on ultimate fibres and fibre bundles. Flax fiber is 10–100 cm in length. Explain the process of making yarn from fibre. Researchers report about different new cellulose sources, however mainly from terrestrial plant origin. Natural fibres provide stiffness and strength to the composite and are easily recyclable. The diameter of microfibrils is between 10-30nm [John 2008]. Physical Characteristics. [Jarabo 2012]. The plant, now cultivated in almost all parts of the world, is supposed by many to have been first known in Egypt, or possibly in the elevated plains of central Asia; but though no doubt a native of warm climates, the fibre attains its greatest fineness and perfection in temperate regions. The bundles consist of 10 to 25 elementary fibres, with the length of 2 to 5 mm and a diameter of 10 to 50 μm. Annually renewable resources, e.g. Furthermore, cellulose molecules are, during the course of biosynthesis, arranged in morphological units elementary fibrils. Another desirable property of jute is that it is quite lustrous. d. Wool. Flax fibre is obtained from the stems of the LINUM USITATISSIMUM plant, belonging to the LINACÆ family. We are IntechOpen, the world's leading publisher of Open Access books. Linen fiber is relatively smooth, straight and lustrous, linen fiber is more brittle and less flexible than cotton.It is more difficult to prepare and spin into yarn. The most important fibre of this class is cotton. The fibre-samples were obtained in a bio-refinery, after the liquid phase containing proteins and lactic acid was eliminated from the ensiled and green grasses, respectively. Kapok fibres are 10–35 mm long, with a diameter of 20–43 μm. Sclerenchyma gives mechanical strength and rigidity to the plant, since it is usually a supporting tissue in plants. Linum angostifolium, the wild ancestor of flax, can be found from the Black Sea to the Canary Islands. Wool. Cornstalks as a potential for fibres extraction were studied by Reddy and Yang [Reddy 2005/2]. The seeds, however, will ripen after the plant is gathered, if they be allowed to remain on the plant for a time. The diameter of fibers is between 70 lm to 400 μm. The term "linseed" refers to brown or yellow seed types containing 35 to 45% oil and 18 to 26% protein. Many plant fibres are produced as field crops. Natural cellulose fibres have successfully proven their qualities when also taking into account an ecological view of fibre materials. Cotton. Legumes are presented by: White clover (Trifolium repens), Red clover (Trifolium pratense), Lucerne (Medicago sativa) [Holmes 1989]. Though flax has lost some of its value as a commercial fibre crop owing to the availability of synthetic fibres, flaxseed has grown in popularity as a health food, and flax remains economically … wood fibres, sisal, pineapple leaves, coconut husk fibres and bananas, mengkuang leaves (Pandanus tectorius) [Sheltami 2012], mulberry bark [Li 2009]. Natural fibres refer to fibres that occur within nature, and are found in vegetables respectively plants (cellulose fibres), animals (protein fibres) and minerals (asbestos). HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. Cotton fruit bursts when mature, revealing a tuft of fibres with the length from 25 to 60 mm and diameters varying between 12 and 45 μm. These fibres therefore are inherently incompatible with hydrophobic thermoplastics, such as polyolefins [John 2008]. Flax is also called linseed and is an edible seed and oil. The microstructure, thermal and mechanical properties of wheat straw fibres have been examined and compared to flax straw fibres with an idea of using these natural fibres as reinforcing additives for thermoplastics [Hornsby 1997]. Hop (Humulus lupulus L.) belongs to the family Cannabaceae and genus cannabis that includes hemp. In addition they contain other substances such as hemicelluloses 17% and lignin 2-3%, as well as waxes 2%, pectins 10% and natural colouring matters [Mather 2011, Mohanty 2005]. Whereas the fibre extraction is simple, fibres are cheap and of appropriate properties elephant grass is also suitable for composites used for lightweight structures preparation . Abstract Flax (Linum usitatissimum) is a bast fibre plant cultivated for the production of fibres, for use in a wide range of woven and non-woven end uses. Man-made fibres are those that are not present in nature, although they may be composed of naturally-occurring materials. 3. We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities. Unless the weather is particularly warm and dry, flax requires little … >> These fibers undergo many processes to be converted finally into linen, which is used to make apparels, tablecloth, and bed sheets. Moreover, flax fibers are used to make linen. The cells are polygonal in transverse section and connected between themselves by sclerenchyma middle lamellas. It is also known as linen fiber. growth location, season and leaf level. Reddy and Yang have collected structural characteristics and biofibres properties (Table1) [Reddy 2005]. Usually, the fibre is creamy white in color and is silky to the touch after processing is done on it. The secondary cell wall is formed by successive deposition of cellulose layers, which are divided in three sub-layers (S1, S2 and S3), of which the middle layer is the most important for fibres mechanical properties. Ramie is a herbaceous perennial plant in the nettle family Urticaceae, native to eastern Asia. Comparing chemical structure of hemp, jute and bamboo, lignin and hemicellulose contents in bamboo are far higher than that of the flax fibres, and almost as much as that of the jute fibres (Hemicellulose content: bamboo 12.49%, jute 13.53%, flax 11.62; lignin content: bamboo: 10.15%, jute 13.30%, flax 2.78%). Introduction. In Zostera marina a very interesting plant structure was observed. Different cellulose fibres can be used for textile and technical applications, e.g. Several techniques are used for extraction of conventional bast fibres: (i) Dew retting by the action of dew, sun, and fungi on the plants spread out on the ground, (ii) Water retting is conducted in rivers or pools through bacterial action and takes 2–4 weeks, (iii) For chemical retting solutions of different chemicals are used, e.g. The secondary wall of the fibres consist of three distinct layers, which include closely packed parallel fibrils with spiral winding of 25 – 30° and represent the majority of cellulose within the fibres. Bamboo is a very-fast growing grass. The fibres of the plant, when grown for Flax, are found to be softer and stronger when the blossom has just fallen and the stalk begins to turn yellow before the leaves fall, than if left standing till the seeds are quite mature. Because of high and different content of non-cellulose substances in various plant fibres the fibres' crystallinity is different. After it is processed into threads and fabrics, it is called linen. Pulp properties, chemical composition and cell wall architecture was researched. Cross-marking is rare, and fibre tips pointed and often flat and ribbon –like. Types of Fibres, Fibre to Fabric, Class 6. Kapok is a smooth, unicellular, cylindrically shaped, twist less fibre. Lignocellulosic agricultural by-products are a promising and beneficial source for cellulose fibres. Fibres were reinforcing a matrix and thereby forming a composite structure. flax, hemp, etc. The length of the sisal fibre varies between 0.6 and 1.5 m and its diameters range from 100 to 300 μm [Mohanty 2005]. Sfiligoj et al. x^���%��&�?�"~Ƒ)N;�7�ޱ�UiT�ꋦ���;fS�#�2��V���L]cg恗�����UۚLY�︓ � ���ꏯ�~��o� W!��t���������W�y]�@�p��yY�J��r�������)���v����=-j��u������^��S��]�N�^��i�^��),������HO~s�W����o^���'�4��. Depending on their physical properties and cellulose content lingocellulose fibres can be used for various applications. Environmental friendly fibres extracted from bamboo, which is renewable, fast growing, degradable, and does not occupy cultivated land are economically efficient and especially useful to grow in hilly areas. Image: Natrij – Public Domain The image above shows a hemp stem. The differences between the procedures are not only in expenses and process duration but the most important the quality and uniformity of retted fibres. Green composites were prepared from pineapple leaf fibres and soy-based resin. Linen fiber is relatively smooth, straight and lustrous, linen fiber is more brittle and less flexible than cotton.It is more difficult to prepare and spin into yarn. The quality of flax depends on the growing conditions, the age of the plant, and fibre processing. Microfibrillar angle MFA of bamboo is 20-100, of coir 410-450, of flax 100, of jute 80, of ramie 7.50, of sisal fibres 200 [Blackburn 2005] and of cotton 20-300 [Morton 1993]. Fibres from these plants can be considered to be totally renewable and biodegradable. Fibres are also associated with the xylem and phloem tissue of monocotyledonous and dicotyledonous plant stems and leaves. Fibers of flax are obtained from its stem. Different fibres have been studied by several authors; their properties were determined and compared to the properties of conventional fibres. Cellulose crystallites in hop and hemp fibres are regularly distributed and are also parallel to the fibre axis and to each other. In addition to, on fibre surface calcium oxalates crystal structures were observed. Thereby the pectin structures connecting fibres with other plant tissues were loosed and the mechanical separation of the elementary fibres or fibre bundles was performed [Sfiligoj-Smole 2011]. Fibres are composed of 57% cellulose, 38% of non-cellulosic polysaccharides (10%pectins and 28% hemicellulose) and 5% of residual matter [Davies 2007]. Currently bast fibres are raw materials not only used for the textile industry but also for modern environmentally friendly composites used in different areas of applications like building materials, particle boards, insulation boards, food, cosmetics, medicine and source for other biopolymers etc. Sclerenchyma cells in stalk rind were more lignified than those in other tissues. These support the stem and also helps the conductive cells of the phloem in their function. A high content of fibres was detected in stems regardless the fibres origin. Fibres are running at the surface of the plant stem, which is about 1 m height and 2 – 3 mm thick in the diameter [Blackburn 2005]. The longitudinal shape is approximately cylindrical. Shives are ideal for chipboards or animal bedding. The plant was up to 1.2 m long. Linen fabric is made from the cellulose fibers that grow inside of the stalks of the flax plant, or Linum usitatissimum, one of the oldest cultivated plants in human history. Elementary fibres with the length of 0.7 -1.5mm and cell diameter of 15 – 35 μm which is comparable to rice and wheat straw fibres were extracted and analysed. >> The flax plant has many applications for each part: it is virtually impossible to have waste. When untreated stems were processed fibre bundles were formed from a bigger number of cells and a mean diameter of 164μm was determined for these fibres. depict toil in large flax fields, and the tombs themselves contain intricate examples of early linen textiles. c. Silk cotton. Sorption properties of these fibres (banana and bagasse: 8.57±0.19 and 9.21±0.01, respectively ) are very similar as cotton fibres, however moisture content in Sponge gourd fibres at standard climate conditions is significantly lower ( 4.79±0.02) [Guimarăes 2009]. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. Flax (Linum usitatissimum) is an annual plant from the Linaceae family. It was found that all surface modifications enhanced adhesion and tensile properties [Joshy 2007]. In addition to, stem’s cross-section is demonstrated on Figure 10. The most common way is a biological treatment by an enzymatic or bacterial action on the pectinous matter of the stem. Jute is a natural fibre obtained as an extract from the bark of the white jute plant Corchorus capsularis and to a lesser extent from tossa jute (Corchorus olitorius) [Mohanty 2005]. Instead of atmospheric retting chemical methods and enzyme retting with pectinases, hemicellulases and cellulases is used, however fibre properties depend on extraction conditions significantly. People in various parts of the world began weaving linen at least several thousand years ago. The ends of fibres are slightly tapered and blunt [Hearle 1963]. Fibres mechanical properties are: tensile strengh is 185 MPA, tensile modulus is 7.40 GPa and elongation at break 2.50% . With a little help of the sun, flax plants on one hectare absorb more than a 3,7 metric tons of carbon dioxide and convert it into oxygen. Bast fibre is the fibre generally found in the phloem of dicot plants. Linum flax has been actively cultivated for fibre, linseed oil and its many derivatives (including such materials as linoleum) since Babylonian days. /Parent 2 0 R Login to your personal dashboard for more detailed statistics on your publications. Help us write another book on this subject and reach those readers. The tensile strength is 0.84 cN/dtex (93.3 MPa), Young’s module 4 GPa, and breaking elongation 1.2% [Mwaikamno 2001]. They are the raw materials which are available in the form of thin, long … In addition to, hemp core fibres from agricultural waste industrial hemp straw with the length between 5-10 mm were studied by Jarabo et al. In addition to, manufacture, use and removal of traditional textile materials are now considered more critically because of increasing environmental consciousness and the demands of legislative authorities. The following points highlight the five main types of fibre plants. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. The fibre cross-section changes from a beanlike shape at the butt end to rounded form at the tip end of the fibres. The fibres are resistant to alkali but degraded by acids. The main polymers involved in the composition of plant fibers are cellulose, hemicelluloses, lignin and pectin. Flax is also a plant that gives natural fibres. From the diffraction patterns of cellulose in hop stem fibres cellulose crystalline structure was determined. << As a kind of abundant and renewable agricultural residue, corn (Zea mays L.) stover, that refers a combination of corn stalk (stem) and leaf, could be a low-cost and sustainable source for energy and chemicals in future. Ultimate fibres extracted from agricultural by-products are round, polygonal or elliptical in cross section and have a lumen in the centre. They are classified into three main groups: those made by transformation of natural polymers (regenerated fibres), those made from synthetic polymers (synthetic fibres), and those made from inorganic materials (fibres made of metal, ceramics, and carbon or glass) [BISFA.2006]. Line fibre can be incredibly long – depending on the height of the plant, a single strand may be up to 5 metres in length. Flax fibres are not as twisted as cotton fibres, but both have a lumen in the centre. A schematic view of the multi-scale structures of flax from stem to the cellulosic fibrils is given in Fig. Beside the traditional textile application of hemp numerous new directions emerge: building and isolation materials, composite materials, special cellulose materials (papers), technical textile, geotextiles and agricultural textile, oil based products, items for agriculture and horticulture etc. Silk fibre is drawn from the cocoon of silkworm. Flax is a bast fiber which is cultivated in cold and humid condition. The main disadvantage of ramie is its low elasticity (elongation at break is 3-7%), which means that it is stiff and brittle [Mather 2011]. This characteristic results in compounding difficulties leading to non-uniform dispersion of fibres within the matrix which influences composite properties. This plant really loves CO 2. Some examples of synthetic fibres are polyester, nylon and acrylic. There are many potential specific utilization possibilities for kenaf whole stalk and outer bast fibres, including paper products, textiles, composites, building materials, absorbents, etc. This outer wax layer protects the primary wall, which is composed of cellulose crystalline fibrils. Phase Iβ is a monoclinic unit cell having space group P21 and dimensions a = 0.801nm, b = 0.817nm, c = 1.036 nm, ß = 97.3º and very close to the cell proposed by Meyer, Mark and Misch. Flax is grown for its seeds, which can be ground into a meal or turned into linseed oil, a product used as a nutritional supplement and as an ingredient in many wood-finishing products. Fibre from the industrial hemp plant is one of nature’s wonders – it’s used in everything from stuffing furnishings to high quality textiles.. There are many who use the names flax and linen almost interchangeably whereas, they are two separate things though linen is a product obtained from the stem of the flax plant. viii. Nanocrystals are much smaller. Also other natural cellulose fibres have been used for composite preparation. An additional possibility is to impregnate cellulose fibres in monomer solution, follows the in-situ catalyst, heat or UV polymerisation [George 2001]. Morphological characteristics of fibres were microscopically observed. Fibres’ diameters are dependent on the procedure of fibres isolation. The cell wall thickness is about 1–3 μm. Phase Iα corresponds to a triclinic unit cell with space group P1 and dimensions a = 0.674nm, b = 0.593nm c = 1.036nm, α= 117º, γ = 113º and ß = 97.3º [O'Sullivan 1997]. Flax is stronger than cotton as its polymers lie almost parallel to the fiber axis. Many traditions are associated with this useful plant. P.Davis et al. But fibres from marine sources offer addition options when appropriate species are identified. But, a combined microbial and chemical treatment is very effective and economical. Unidirectional isora fibre reinforced polyester composites were prepared by compression moulding. Of huge interest are especially agricultural wastes from cultures which are primary grown for food industry, and their plant wastes additionally containing fibres. b. Flax is a bast fiber which is cultivated in cold and humid condition. Pre-treatment of stems facilitates sclerenchyma cells separation from other plant tissues, and fibres’ diameter for fibres isolated from pre-treated stems was 42.61μm. Besides, stems were subjected to chemical treatment in alkaline medium (1%NaOH; different treatment times and temperatures were used; sample A – 1day treatment, room temperature; sample B – 11days treatment, room temperature; sample C – 1 hour T = 1000C). Recently, the interest for renewable resources for fibres particularly of plant origin is increasing. The fiber of the bark is used for making thread and cloth, called linen, cambric, lawn, lace, etc. To achieve strong adhesion at the interfaces which is needed for an effective transfer of stress and load distribution through out the interface, sometimes surface modification is needed. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. Technically, linen is a vegetable. Microfibrillar orientation is different for different types of cellulose native fibres. The types are: 1. Like cotton, flax fibre is a cellulose fibre, however its structure is more crystalline, making it stronger, and stiffer to handle, and more easily wrinkled. Image: CC BY-SA 3.0, Link. A wide lumen is filled with air and does not collapse like cotton. The most important fibres of this group are sisal, henequen and abaca. a) Longitudinal view (10000× magnification) and b) cross-section (200× magnification) of hemp fibre. jute, hemp or coir. It is also known as skin fibre. Cellulose content in sisal fibres is about 70%. Lumen is surrounded by the tertiary wall. Sorption properties of hop fibres are comparable to cotton properties and slightly lower than that of hemp [Reddy 2009]. It is a natural, cellulosic, multi-cellular bast fiber. The monoclinic spatial model for the unit cell of native cellulose is cellulose I crystal modification. Fibres are also made from chemical substances, which are not obtained from plant or animal sources. The pattern obtained by stripping the bark or “ bast fibres ), pectin 1.4.
