Moreover, the larger fibre diameter of the flax fibre pulp resulted in poorer packing efficiency and therefore a higher porosity of 67% compared with preforms made with BC or NFC as a binder, which had a porosity of 60%. Interest in ramie is being rekindled and is appearing more often in the fibre content of clothing and textiles. Chemical Composition of Ramie: Ramie fiber is degummed for making it usable as textile fiber. 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). Most of the current research still deals with durability aspects of cellulose fibres and other alternative fibres. The physical properties of Ramie fibre exhibited high tenacity, high luster and brightness. Improved durability of natural fibre composites has been achieved with the employment of mineral admixtures, such as rice husk ash or metakaolin in order to reduce the alkalinity of the cement paste [Rodrigues et al., 2006, 2010). However less effort has been documented regarding the sustainability of the product. 3.16 shows what happens in the fiber cell wall with refining/fibrillation or nanofibrillation.31,32. ; Nishino, T. Comparative effect of mechanical beating and nanofibrillation of cellulose on paper properties made from bagasse and softwood pulps. (2016) examined flax fibre nonwovens typically in a web which are mechanically bonded (via entanglement and interlocking of fibres) or thermally bonded (by melting of polymer fibres). (1999) described detailed findings on the chemical composition of ramie fibre. 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. Jute Color: Jute fiber can be White, Yellow, Brown or Grey. These two fibres i.e. G. Koronis, A. Silva, in Green Composites for Automotive Applications, 2019. 3.3). China is a pioneer in, Tribology of Natural Fiber Polymer Composites. It strongly holds its shape and does not shrink. Its luster appearance improves with washing. From: Natural Fibre Reinforced Vinyl Ester and Vinyl Polymer Composites, 2018, K.A. http://dx.doi.org/10.1016/j.carbpol.2013.05.032, ) is a bast fibre extracted from the stems of the ramie plant. Thakur et al. Ultimate tensile strength frequency distribution of the sisal fibers.22, These characteristics of the bond between the lignocellulosic macrofiber reinforcement in cement-based materials still remain relatively unexplored. The diameter range distributions are illustrated in Fig. Pineapple, Ramie, Bamboo, Banana, Bagasse etc. These interactions create an interphase region which is a three-dimensional region near to the fiber with properties different from either the fiber or the matrix.23, Figure 3.15. 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. Relevant characteristics of vegetable fibers. Digital images of composites prepared with the three methods after burning tests strongly confirm the biocomposite prepared with the third strategy holds better flame retardancy performance, as shown in Fig. 19.7. 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. Your email address will not be published. Researchers have also characterized the fibreâs properties, such as bundle tenacity, breaking elongation, fibre fineness in tex, Whiteness Index in Hunter scale, Yellowness Index and Brightness Index at different stages of fibre (decorticated ramie fibre, degummed ramie fibre and bleached ramie fibre) used to develop these cotton-ramie blends for fashion fabric (Anonymous, 2002a). 3.11). 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. 3.15 for some examples). That said ramie will use jute's indicator value. Mechanical properties of compositesa. High performance fibre-reinforced concrete (FRC) for civil engineering applications, T.H. Ramie fiber is used for making bled with other fibers like cotton, wool, flax, polyester, acrylic and silk. Figure 3.12. 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. In wet condition, strength of ramie fibers is increased. Ramie fibres exhibit excellent mechanical properties, i.e. The researchers concluded that the layer-by-layer filtration process resulted in flax nonwovens that produced better tensile and flexural properties of composite, owing to the better distribution of the fibres in the form of a nanocellulose network throughout the preform. In this method, the cellulose pulp was passed between a static grindstone and a rotating grindstone revolving at 1700 rpm. 3.17A). A Review on Composition and Properties of Banana Fibers Ravi Bhatnagar, Gourav Gupta, Sachin Yadav ... straw wheat, oats, bagasse, barley, grass reeds, banana fiber, oil palm empty fruit bunch, coir, sisal, cotton, kenaf, ramie, water pennywort, paper-mulberry, kapok, abaca, pineapple leaf fiber.

Effect of aluminum trihydroxide on flame retardancy and dynamic mechanical and tensile properties of kenaf/poly (lactic acid) green composites. Digital photos for poly (lactic acid)-based green composites after LOI tests. 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). (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. The produc-tion of banana in India is 13.5 million tons per annual. Required fields are marked *, Chemical Composition of Ramie || Mechanical Properties of Ramie Fiber. Ramie is a flowering plant in the nettle family Urticaceae, native to eastern Asia. The fibre is white, lustrous, and fine like silk. He also emphasized different developments in the area of technologies concerning ramie fibre processing. 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. The main effect of refinement (refiner or grinding) in cellulose fiber structure is the fibrillation of the fibersâ surface because of the mechanical treatment. By blending with wool, the fabric is lighter and shrinking is minimized. Ribeiro Borges, in, Advanced Fibre-Reinforced Polymer (FRP) Composites for Structural Applications. Fig. Dry spinning results in a harsh, hairy yarn. Carding, air-laying and wet-laid techniques could be used for web formation. The present study explores the possibilities of producing degummed ramie fibre by chemical method and blending of this natural fibre with jute with the aim to develop the desired properties. The world freight rates depend on volume, weight, and commodity value of the cargo. They further used various types of nanocellulose, including nanofibrillated cellulose (NFC), BC and pulp fibres, to manufacture flax nonwovens. Ramie fabric is used for apparel including suits, skirts, jackets, dresses, shirts, blouses, pants and handkerchiefs. In addition, wood and sisal fibres are constituents of cement composite panel lining, eaves, soffits, and insulation construction materials. This was attributed to the low surface area of pulp compared with BC and NFC, which led to a lower contact area between the flax fibres and pulp. The demand of ramie fiber is increasing for its luster, strength, excellent microbial resistance and valuable hygienic properties. 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). 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. The resulting part is 27% lighter than the baseline scenario with comparable mechanical properties.

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. Ramie (Boehmeria nivea) is a bast fibre extracted from the stems of the ramie plant. 3.17 shows what happens in the fiber cell wall after refining. Indian 10urnal of Fibre & Textile Research Vol. It was been found in the literature (Anonymous, 2015) that Ramie fibre is also known as China grass, grass linen, rhea and grass cloth. It is also commonly used as a substitute for flax/linen and can be blended with silk fibres. 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. As far as the fibre is concerned, ramie is a strong, lustrous, soft and fine bast fibre obtained from inner bark of the plant B. nivea (L) Gaud. As a result, 20% of the matrix volume is renewable, which contributes additionally by decreasing the overall impact of the material and disposal phases. 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).
