Furthermore, the influence of process parameters such as feed rate, stroke frequency and depth of needle penetration on the properties of the geotextiles was observed (Rawal and Anandjiwala, 2007). From: Natural Fibre Reinforced Vinyl Ester and Vinyl Polymer Composites, 2018, K.A. Ribeiro Borges, in, Advanced Fibre-Reinforced Polymer (FRP) Composites for Structural Applications. They further used various types of nanocellulose, including nanofibrillated cellulose (NFC), BC and pulp fibres, to manufacture flax nonwovens. It is said that ramie fibres are one of the oldest natural vegetable fibres, used for thousands of years for fabric and clothing, including ancient Egyptian mummy wraps and shrouds. 3.14. However less effort has been documented regarding the sustainability of the product. In natural fibers’ category, the most used are flax fiber, jute fiber, hemp fiber, and ramie fiber due to better mechanical properties; in comfort application, cotton fiber may be used; and in hometech, silk fiber is used due to its excellent drapability property. The result shows that taking ramie roving as the reinforcement will improve the infiltration properties of the PP matrix to ramie fibers, the reason is that ramie fibers have good orientation and it is loosely arranged in the ramie roving , all of these are benefit to form a good interfacial bonding between fibre and PP resin. Natural fibers are getting attention from researchers and academician to utilize in polymer composites due to their ecofriendly nature and sustainability. Sérgio Francisco Santos, ... Holmer Savastano Junior, in Sustainable and Nonconventional Construction Materials using Inorganic Bonded Fiber Composites, 2017. Their review described different technologies used to manufacture nonwoven fabrics from flax fibres and flax waste. Cellulose : 68.6 – 76.2%, Lignin : 0.6 -0.7%, Hemi-cellulose : 13.1 – 16.7%, Pectin : 1.9%, Wax : 0.3%, Density : 1.50g/cm3, Mechanical Properties of Ramie Fiber: As like chemical properties, ramie fiber consists of mechanical properties. To obtain such good dielectric properties, ramie fibre is treated with an 18% concentration alkali (NaOH) solution.

Flax fibre orientation distribution characteristics of these mats were determined using a fast Fourier transform image analysis algorithm. The possibility of applications for the lignocellulosic fibers has stimulated the interest to modify their surfaces for specific applications. This interaction can occur through three mechanisms: mechanical coupling or micromechanical interlocking of the two materials, physical coupling such as van der Waals or electrostatic interaction, and covalent bonding (by way of a coupling agent) between the fiber and the matrix (see Fig. 3.12A), lignocellulosic fibers are nonuniform not only in their cross-section, but also along the longitudinal axis, as shown in Fig. About 20 fibres ... to that in the all-ramie yam. The volume fraction of longitudinal ramie fibers controls the overall tensile properties. Chemical Properties: The chemical properties of fibers include the effects of chemical agents including acids, bases, oxidizing agents, reducing agents, and biological agents such as molds and mildews on the fiber and light and heat induced chemical changes within the fiber. 3.16 shows what happens in the fiber cell wall with refining/fibrillation or nanofibrillation.31,32. The eco-score in pts for each alternative is calculated according to the tkm unit, where, tkm=weightintonnesâdistanceinkm. The micro/nanofibrils were more exposed in the refined pulp (Fig. The world freight rates depend on volume, weight, and commodity value of the cargo. High-quality paper goods such as bank notes and cigarette papers are produced from the short fibres. Influence of ammonium polyphosphate on the flame retardancy and mechanical properties of ramie fiber-reinforced poly (lactic acid) biocomposites.

T able 4 shows mechanical properties of bagasse fibers, by which we use fibers as reinforcement for a good mechanical … P. Peças, ... E. Henriques, in Green Composites for Automotive Applications, 2019. They found that complete removal of the gum from the fibre is similar to that of pure cellulose, about 94%â95% α-cellulose. Composites Part A: Applied Science and Manufacturing 41, 954â963, copyright 2010, with permission from Elsevier Press. 276-278 Chemical composition of some varieties of ramie and their fibre characteristics R Thakur" , C R Sarkar & R Sarmahb Department of Biochemistry & Agricultural Chemistry, Assam Agricultural University, lorhat 7X5 13. NCCs are rigid rod-like crystals with a diameter in the range of 10â20 nm and lengths of a few hundred nanometers. (2014) made an extensive review of flax fibre-based nonwovens. Ramie fiber is used for making bled with other fibers like cotton, wool, flax, polyester, acrylic and silk. The true ramie or China grass is also called Chinese plant or white ramie. The SimaPro jute's indicator includes the cultivation and processing to yarn. Different international companies (Joanna Hope linen-blend trousers, for example) market ramie-linen kurti for women for casual wear. Figure 3.18. (0) direction indicates that the ramie fibers are aligned along the test direction, whereas (90) direction is referred to whenever the ramie fibers are perpendicular to the test direction. Thus, problems between lignocellulosic fiber interface and matrix must be analyzed differently from composites reinforced with synthetic fibers, although similar physical and mechanical parameters can be used. Because the fashion industry is becoming increasingly eco-conscious, the popularity of ramie will continue to rise. Fibre linear density or tex was measured on VIBROSCOPE. The costs and environmental impacts during the raw material production and transport phase are presented in Table 11.7. Digital photos of composites prepared with three methods after burning tests. Based on their sustainability, plant fibers such as hemp, jute, sisal, kenaf, banana, and ramie fibers are replacing synthetic fibers in increasing numbers of fiber-reinforced composites. Their availability, good mechanical properties, easy processability, low cost, low density, and biodegradability makes them an attractive choice. The main problem associated with the ramie fibre is its gum content. The physical properties of Ramie fibre exhibited high tenacity, high luster and brightness. It is the oldest textile fiber of plant origin. Fig. 19.8 gives the heat release rate curves for four composites tested on cone calorimeter. The versatility of ramie fibre allows it to be made into fine yarn for garments ranging from dresses and suits to sportswear and jeans. In that study they showed that bacterial cellulose (BC) can be used as an effective binder to produce rigid and robust natural fibre nonwovens without the need for polymer binders. (2010a, 2010b, 2011) have recently studied the physical and mechanical properties of long sisal-reinforced cement composites, as well as the influence of fibre shape and morphology on the cracking behaviour. NCC has high specific strength and modulus making it a promising reinforcing agent for polymers [43]. To pre-pare a sample for lignin and cellulose analysis, ethanol-benzene soluble extractives were investigated and removed by soaking in a solvent for 6h to remove the extra waxes, fats, and alcohol-soluble resins. The aim of present study is to improve mechanical properties of epoxy composites by reinforcing Indian ramie fiber at different loadings (0% to 40% by wt.). Based on Afra, E.; Yousefi, H.; Hadilama, M.M. In China it is known as China grass and different fashion products such as womenâs dress material, shirts, suits and handicraft products are popular there. ; Nishino, T. Comparative effect of mechanical beating and nanofibrillation of cellulose on paper properties made from bagasse and softwood pulps. The use of lignocellulosic fibers, such as wood (eucalyptus and pines) and nonwood (sisal, green coconut, yam, bamboo, fique, hemp, flax, jute, curauá, and ramie) fibers, as reinforcement in cement-based composites has been studied to partially replace the synthetic counterparts, especially glass and polymeric fibers in construction materials.13,19,20 However, in addition to the problem of durability there is the issue of the interface between the fibers with the cementitious matrix. Furthermore, changes in the mechanical properties over time can occur due to microstructural changes in the fiberâmatrix interface and bulk, as a consequence of the continued hydration process that occurs in the fiber surroundings, i.e., if the interfacial transition zone becomes denser due to reprecipitation of cement hydration products in the porous layers. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Furthermore, different physical, mechanical and functional properties of flax nonwovens reported by various researchers have been described. Figure 3.11. In order to determine the life cycle impact assessment of the natural fibers using the SimaPro software, some adaptations needed to be made. Maity et al. Your email address will not be published. They are-, Fiber Diameter : 0.034 mm, Fracture Load : 0.467 N, Fracture Stain : 0.025%. Fabrics made of 100% long and fine ramie fibres are lightweight and silky. The fibre possesses some very valuable properties because of its silky, luster, unparallel strength, durability and its suitability to blend with all other natural and manmade fibres. By this improvement, labor use will be additionally optimized in terms of performance. However it is somewhat stiff and brittle, which is great for coarser products such as twine, rope, wallpaper and nets. This depends on whether the fiber is taken from stems, stalks, or leaves, the climate and soil conditions at the plant location, the age of the plant, and the preconditioning of the fibers. Figure 19.9. Jute Fiber has some standard physical properties. Pandey (2007) critically reviewed research work and developments in physical and related properties of ramie, a long vegetable bast fibre. Ramie fibre usually contains as much as 30% gum. High performance fibre-reinforced concrete (FRC) for civil engineering applications, T.H. 24, December 1999, pp. In addition, Woo and Cho (2013) investigated effects of aluminum trihydroxide (ATH) on the flame retardancy of kenaf/PLA green composites. Finally, potential areas of applications for flax nonwovens, such as filtration, medical textiles, automotive textiles, composites and geotextiles were highlighted. Today, high-performance plant fiberâbased biocomposites have been produced after several years of research which show their potential. The fiber is composed of pure cellulose being resistant to microbial attacks. The important concern about ramie is the removal of gum content from the extracted fibres, which contain as much as 30% gum per weight of fibre. Effect of aluminum trihydroxide on flame retardancy and dynamic mechanical and tensile properties of kenaf/poly (lactic acid) green composites. It strongly holds its shape and does not shrink. The type of mat used is imported from a Chinese supplier (based in Shanghai) by sea freight and is expected to have more energy related to transportation than e-glass, which is fabricated by a manufacturer close to the industrial area where Ancel is located. The main effect of refinement (refiner or grinding) in cellulose fiber structure is the fibrillation of the fibersâ surface because of the mechanical treatment. Ramie fibres exhibit excellent mechanical properties, i.e. ... [77] Ramie fiber yarn reinforced composites [104] Jute yarn-Biopol composites [113] Filament 4 A Multi-Component Fiber-reinforced PHEMA-based … Scanning Transmission Electron Microscopy (STEM) of unbleached bamboo nanofibrillated cellulose pulp after 10 cycles by mechanical nanofibrillation method.32. After analyzing, it is found that, ramie fiber is … G. Koronis, A. Silva, in Green Composites for Automotive Applications, 2019. The mechanical characteristics of cement-based composites reinforced with fibers depend not only on the properties of the fiber, but also on the degree to which an applied load is transmitted to the fibers by the matrix phase. breaking strength and density of fibre. Ramie fibres were surface treated in order to enhance the interfacial interaction between ramie natural fibres and vinyl resin matrix. The demand of ramie fiber is increasing for its luster, strength, excellent microbial resistance and valuable hygienic properties. Importantly ramie represents similarities in terms of chemical constituents (Table 1) as well as in fibre properties viz. In the majority of the cases, the fiber surface modification is an essential requirement to improve the interfacial compatibility between fiber and matrix (improving adhesion) and thus yielding enhanced mechanical performance of the fiberâcement interface.13,22,25â28, In addition, new approaches on lignocellulosic fibers are used to minimize their hydrophilic nature in cement matrix, such as chemical and physical treatments and a thermal treatment named the hornification process.29,30 Furthermore, mechanical treatments also are applied as fibrillation of the fibersâ surface. The quantities disclosed are for one component. Flax fibre mats (nominal weight, 750 g/m2) produced by the parallel-laying method had a prominent principal direction of fibre orientation, whereas mats produced by the cross-laying method had a nearly random fibre orientation. Because of the trend toward natural fibres, expect to see ramie become even more popular. Its absorbency properties are extremely high. These products appear to be considerably durable, given that nearly 10 years have passed since the beginning of commercial use. For the bonnet production, the materials are obtained from different places around the world. (1999) described detailed findings on the chemical composition of ramie fibre. In Africa, sisal fibre-reinforced concrete has been used extensively for making roof tiles, corrugated sheets, pipes, silos, and gas and water tanks. These two fibres i.e. The digital photos of PLA/kenaf composite without and with ATH after LOI tests clearly show that the latter holds better flame retardancy than the former (see Fig. 19.9). Both BC and NFC served as excellent binders for loose flax fibres owing to their high surface area, whereas pulp fibres were a poor binder for flax fibres. The diameter range distributions are illustrated in Fig. All composites performance is presented in Table 5.1, where the RBP is ramie-reinforced bio-polyester and GFC is the e-glass fiber baseline composite. The ramie-reinforced hood weighs 1.79 kg of which 0.4 kg is ramie and the remainder is biopolyester with fiber Vf at 18%. Its luster appearance improves with washing. Ramie fiber is used for blending with other fibers. The process becomes slower due to its moderate pressure (assisted by vacuum). Thus, to solve the problem the ramie fiber needs to adopt the indicator value of other natural fiber and then model it by adding any difference to it. Ramie fiber is collected from the ramie plant. Macrofibrils and microfibrils are constituted of cellulose nanocrystals (also reported in the literature as cellulose whiskers), nanofibrils, cellulose crystallites, or crystals that are considered as the crystalline domains of lignocellulosic fibers, and can be isolated by several chemical and mechanical methods (Fig. Figure 3.13. Dyeing could be done easily. (A) The molecular structure of cellulose, with glucose molecules alternately rotated 180° (solid line, covalent bonds; dashed line, hydrogen bonds); (B) cellulose microfibrils, with both crystalline and noncrystalline regions, aggregated into a macrofibril.33, Fig. The employment of natural fibres, such as cellulose pulp, sisal, bamboo, hemp, flax, jute, ramie fibres, etc., is restricted to countries where these fibres are easily available. Tensile stress of the cotton-ramie hybrid composites with (90/0) configurations28. For this reason, a statistical distribution of diameters and ultimate strength values must be used to analyze mechanical behavior of lignocellulosic fibers instead of average values, commonly applied in the case of synthetic fibers, as well as the method applied to measure area of fiber cross-section should always be informed in articles and technical texts.22, Figure 3.14. Bleaching could … The demand of ramie fiber is increasing for its luster, strength, excellent microbial resistance and valuable hygienic properties. Plant fibers, particularly the fibers extracted from the bast and leaf of particular plants, find applications in automotive industries while most of the other fibers being studied at the research level and have yet to find large-scale commercial applications. Researchers also investigated the other similar long vegetable fibre-based composites. It is known as eco-friendly fibre resource because ramie fibre has some advantages over synthetic fibres on the environment. Polymer International 59, 242â248, copyright 2009, with permission from the Society of Chemical Industry. 3.17A). The PLA/40 wt% kenaf composite exhibits an LOI value of 23.9, and the LOI was increased up to 39.7 after adding 50 wt% of ATH as flame retardants. (2004) concluded that a reduction in gum content from 20%â30% to 2%â3% using alkali treatment and subsequent bleaching of ramie fibre in blended cotton-ramie yarn spun in the cotton spinning system resulted in a deterioration of the yarnâs strength. To produce fabrics with various improved characteristics, ramie is often blended with other fibres such as cotton. http://dx.doi.org/10.1016/j.carbpol.2013.05.032, ) is a bast fibre extracted from the stems of the ramie plant. Ramie fabric-reinforced thermoset polylactic acid (PLA) composites were prepared by using heat pressing technology. By doing this, creating fabrics from fine linens to coarse canvas gives ramie fibres almost unlimited potential. ... Superior tensile … Schematic depictions of various interactions at the fiberâmatrix interface: (A) micromechanical interlocking; (B) permanent or induced dipole interactions; (C) chemical bonding; (D) chain entanglement/fibrillation; and (E) adhesion by embrittlement of the fiber.23. Since both fibres have their origins in natural plants, it is expected that the products will be environmentally green. (1999) described detailed findings on the chemical composition of ramie fibre. Thakur et al. China is popular for the development of eco-friendly, sustainable, ramie-based textiles for fashion products. Ramie fabric is used for apparel including suits, skirts, jackets, dresses, shirts, blouses, pants and handkerchiefs. Ribeiro Borges, in Advanced Fibre-Reinforced Polymer (FRP) Composites for Structural Applications, 2013. These are – Ultimate Jute Length: 1.5 to 4 mm. The cost of materials takes into account the volume of production of 600 parts/year for the bonnet component. Neither the hemp nor the bagasse fibre composite was capable of resisting termite attack. Fig. Fig. Within the category of long vegetable bast fibre, an extensive review was made by Pandey (2007) on developments in ramie fibre and its potential industrial uses, especially in the area of nonwoven textiles apart from traditional textile applications. Manickam Ramesh, in Handbook of Properties of Textile and Technical Fibres (Second Edition), 2018. They found that complete removal of the gum from the fibre is similar to that of pure cellulose, about 94%–95% α-cellulose. Mechanical properties of compositesa. Hemp fibre is a strong natural fibre similar to flax, kenaf and ramie; it possesses good fibre quality and physical properties of strength, durability and absorbency. Apart from conventional fashion textiles, when ramie fibre is used in industrial applications, it is suitable as an electrical insulation material when used in dry application areas because of its good dielectric properties (Sao et al., 1990). jute and ramie can suitably be blended in modified jute spinning system. In fiber-cement composites, the higher the fibrillar surface of fibers, the higher their capacity to bond with cement matrix.13, Figure 3.17. Jute Fiber Length: 150 to 300 CM (5 to 12 Feet). Schematic illustration: (A) unrefined; (B) refined; and (C) nanofibrillated fibers. The parallel-laid mats had a higher overall compressibility than the cross-laid mats did because of the tendency to nest between layers of parallel fibres, leading to a lower porosity under the same vacuum level, and thus lower overall permeability. An experimental investigation was performed to understand the pullout behavior of sisal fibers from the cement matrix. Ultimate Diameter of Jute: 0.015 to 0.002 mm. Cotton blends result in increased strength, colour and luster whereas rayon blends result in a higher wet strength. He also emphasized different developments in the area of technologies concerning ramie fibre processing. Although the process is more sustainable in the case of the microbial process, it is costly and time-consuming. Nanocrystalline cellulose is generally synthesized by acid hydrolysis of native cellulose, and the properties of final product markedly depend upon reaction time, temperature, and acid concentration. Kraft pulp fibre-reinforced cement has found major commercial applications in the manufacture of flat and corrugated sheet, non-pressure pipes, cable pit, and outdoor fibre-reinforced cement paste or mortar products for gardening (Tait and Akers, 1989). The resulting part is 27% lighter than the baseline scenario with comparable mechanical properties. The higher water/binder ratio close to the fiber leads to a reduction of the fiberâmatrix contact surface, which may result in lower frictional bond stress.21 In this way, there is an additional challenge for the fiber-cement: the hydrophilic nature of the lignocellulosic fibers that depends on surface porosity, lumens, roughness, surface chemical groups, and surface energy in the fiberâmatrix interface (Fig. 3.11). Industrial uses of ramie include parachute fabrics, fire hoses, and canvas. Chemical Composition of Ramie: Ramie fiber is degummed for making it usable as textile fiber. ...

Einsiedel R and Müssig J 2016 Surface properties and fibre-matrix adhesion of man-made … Dry spinning results in a harsh, hairy yarn. Nanocrystalline cellulose (NCC) is a recent development that possesses advantages because of nanoscale dimensions [43,44]. 3.13. Flax, sisal, cotton, coir, ramie, jute, and bamboo fibers are widely used in reinforcing polymer composites [41,42]. 3.15 for some examples). The alternative scenario in comparison with the baseline is a ramie-reinforced polyester hood part that incorporates natural biaxial woven fabrics fiber. Panzera, ... P.H. The fibres are uneven, which gives ramie fabric an appearance similar to linen. They also developed a combined microbial and chemical process. The surface topography and binding force influenced by the treatments were characterized by contact angle and mechanical property. Scanning Electron Microscopy (SEM) micrographs: (A) Polypropylene fiber surface; and (B) Sisal (Agave sisalana) fiber surface. Because both of the fibres are of natural plant origin, the final products are environmentally friendly. However, other reports claim that the tensile strengths of cotton, flax, hemp and ramie are similar. The aim of this review article is to provide a comprehensive review of the foremost appropriate as well as widely used natural fiber reinforced polymer composites (NFPCs) and their applications. Thakur et al. Figure 3.12. Figure 3.3. For all the alternative scenarios, a novel polyester resin with the addition of renewable plant oils name BioPoli 507 [39] was used. Multiwalled carbon nanotubes and sepiolite nanoclays as flame retardants for polylactide and its natural fibre reinforced composites. 3.19 shows nanofibrillated unbleached bamboo organosolv pulp prepared using the mechanical nanofibrillation method. Fig. ... Linwen Zhang, Jinchen Zeng: Natural Fiber Reinforced Plastics (Chemical Industry … They concluded that this combined process is simpler and more economical than the chemical process itself. (2011) suggested in their study that the resin flow characteristics of natural fibre mats made from flax fibre must be taken into consideration in the design and optimization of liquid composite moulding processes. Research demonstrates the processing technology of cotton-ramie blends (Anonymous, 2002a,b) on short-staple spinning system (cotton spinning). The plant is a perennial producing many stalks, each growing from 1.9 to 2.4 m (3 to 8 feet) high. However, because of their natural origin, their mechanical characteristics and density vary significantly with the source of origin. In Tribology of Natural Fiber Polymer Composites, 2008. Carding, air-laying and wet-laid techniques could be used for web formation. However, more precision is attained regarding surface finish and far less manual post-mold rework is required. Ramie/China grass fibres are commonly used in blends for sewing threads, fashion sweaters, fancy clothing and linens. After extraction with ethanol-benzene, … The reinforcing capabilities of plant fibers and their properties have been described in numerous papers. It is critical to control the fiberâmatrix interaction with lignocellulosic fiber, because, differently from synthetic fibers, such as glass and polymeric ones (Fig. 1 Schematic arrangement of Hemp, Ramie Fibers Table 1 Physical properties of materials used Hemp Fiber Ramie Fiber E-glass Fiber Density (g/cm3) 1.48 1.5-1.56 2.5 Young’s modulus (GPa) 30-70 60-128 72.40 Tensile Strength (MPa) 368-800 400-1000 2000-3500 ... fibers are shown in figure 3. Determination of fibre properties-The fibre tex, diameter, crimp frequency and the dry and wet tensile properties were determined for both untreated and alkali treated ramie fibres. Better fiberâmatrix interface adhesion and mechanical performance can be achieved by increasing the specific surface area of the fiber, by reducing the fiber diameter, and by promoting a rough surface with better mechanical anchorage in the matrix.13. Interest in ramie is being rekindled and is appearing more often in the fibre content of clothing and textiles. Table 5.7. The economical process of gum extraction from ramie fibre was developed and the extracted natural gum was used as a natural resin to develop jute particleboard. The chemical properties of the different natural fibers . The refining energy is sufficient to partially rupture the bonds between microfibrils, leading to a more fibrillated surface. Panzera, ... P.H. It was been found in the literature (Anonymous, 2015) that Ramie fibre is also known as China grass, grass linen, rhea and grass cloth. Advanced Composite Materials 22, 451â464, copyright 2013, with permission from Talor and Francis Group. This review paper examines the chemical properties of natural fiber reinforced polymer bonded composites and the processing techniques are compared for the reinforced composite materials. 3.17B) than microfibrils in unrefined fiber (Fig. Ramie fiber is used for making bled with other fibers like cotton, wool, flax, polyester, acrylic and silk.
