However, biological geotextiles resulted in lower vegetation covers compared with the control with negative effectiveness values on the 45° slope of − 33% and − 68% for jute and coir, respectively. However, the spiral structure was found to be considerably modified by swelling. Por otro lado, se evidenció que el método de unión utilizado influye en las propiedades mecánicas de los no tejidos, en los cuales el valor máximo de fuerza de rotura fue de 212,34 N por el método de adhesión química. Jun 2016 1. The electrical properties such as dielectric constant, dielectric dissipation factor and dielectric loss factor were determined with respect to temperature and frequency. This liquid oil can be a non-conventional source of renewable energy if the process is further developed. In this paper, mahogany seeds, sawdust, rice husk and coconut shell are considerable feedstock which are used for pyrolysis system to produce non-conventional fuel. Changes in structural features of jute fiber subjected to (a) limited oxidation using K2S2O8 or NaIO4 and subsequently to (b) treatment with monomeric/oligomeric glycols or acrylamide under specified conditions have been investigated through X-ray defractometry, fourier transform infrared spectroscopy, and differential scanning calorimetry in the present study. In the present study, the influence of several geotextiles (a jute net, a coir blanket and a 3D polyester geogrid placed in two positions) on herbaceous vegetation cover has been evaluated during an eighteen-month field experiment on a hydroseeded experimental roadside slope with 45° and 60° slope gradients in Spain. Potentials for Utilization of Post-Fiber Extraction Waste from Tropical Fruit Production in Brazil – the Example of Banana Pseudo-Stem, Enzyme Treatment in Improving the Quality of Pseudo Stem Fiber of Banana Plant to Use this Bioresource for Making Handmade Paper, Evaluation of erosion control geotextiles on steep slopes. The common name, scientific name and plant family of coconut fibre is Coir, Cocos nucifera and Arecaceae (Palm), respectively. The present work reveals that it is possible to grow sisal fibre of specified variety/species (Agave sisalana) having much balanced property parameters for producing international quality products (viz., ropes, cordages agricultural binders). Electrical power of 0.13 W is generated within 228 days of durability or it is decreased by 135 mV/1000 h or 16% (v/v)/1000 h. International Journal of Civil Engineering and Technology. India is one of the major exporters of sisal ropes and cordages but the raw fibres are imported from Africa and some other places. ), Geosynthetics-New Horozons. In general, the three geotextiles produced larger runoff volumes indicating that slopes treated with geotextiles absorbed less water rendering the soil to be less saturated than the control, thereby presenting effectiveness in preventing soil erosion. Adamson It has been observed that benzoylation and graft copolymerization enhanced the thermal stability and crystallinity of sisal fibers. The effects of geotextiles on runoff and soil erosion have been documented; however, the conditions studied to date have been limited and are insufficient for the optimization of the selection and application of geotextiles for other sites. FAO. Request PDF | Properties of Coconut Fiber | Coconut fiber is available by dehusking between skin and shell. loss brought about by the action of surface runoff. These are multi-cellular, lignocellulosic, hard, a very coarse, and rigid variety of natural fruit fiber. We critically discuss the use of plant fibres as reinforcement for the production of bio-based, renewable or green polymer composites. A fully matured coconut tree can produce 50–100 coconuts per year, and each fruit takes one year to ripen. Three mixing ratio by weight were varied 1:2:1, 1:1:1, and 2:1:2, respectively (cement : coconut coir : water). Vetiver grass is more effective in reinforcing soil and controlling up to 56% of the soil erosion than no grass at all. Biodegradable coir geotextiles combined with native seeds can be used to restore degraded forest areas. The changes in surface morphology of MCH and YCH throughout the process were also observed. SEM and XRD is used in this study to evaluate gas composition effect on MCFC anode morphology. The increased adhesion between fiber and matrix was also observed by SEM.

Considering its low cost and ability to be produced at a large-scale, biomass-derived HSAAC is a promising electrode material that may advance high-energy rechargeable lithium-sulfur batteries toward use in practical applications. This paper is the first of two in which the performance of erosion control geotextiles on steep slopes (45° and 60°) has been assessed. Structure and properties of natural fibers have an obvious effect on the mechanical properties of the biocomposite materials. The chemical composition and FTIR analyses revealed a reduction of the hemicelluloses content in the fibers treated with NaOCl/NaOH and, consequently, this fiber showed a greater exposure of cellulose and a reduction in thermal stability. Soil encountered in many sites are either sound enough to withstand designed load from proposed structures to be erected upon them or there may be need to have the soil modified. D. Coconut Fibre Fig. Results were compared with a control plot. The treatment of raw coconut fibre with a combination of sodium sulphide, sodium hydroxide, sodium carbonate, reduce retting time from 6 to 12 months to 2 h. Chemical treatment decreases the linear density (about 36%), diameter (about 35%), and flexural rigidity (about 72%), ultimately resulting in much softer fibre. Its advantages are agro-renewability, biodegradability and a good blend of strength, length, extensibility, moisture regain, and high durability or resistance against sunlight, saline water, microbes, etc. DPWH Standard Specification for Item 622-Coconet Bio-Engineering Solutions" possesses the properties suited for a soil erosion control blanket. 1, 2014.

The Coconut coir fibers are capable of resisting strain 4-6 times greater than other fibres. Laboratory tests. Thus, its surface installation seems to be a better option. Thus, all sizes are effective in controlling soil erosion compared to the control setup and the 0.5x0.5-inch eye-opening size is the best among others. There was no significant difference in mechanical properties of the samples. Baconet was laid out on a 45° slope and in 4 meters x 5 meters plot in Mogpog, Marinduque. In most countries coir is discarded as waste, sometimes it is used as a fuel, in few instances it is processed into products. Certain agricultural plants which are producing high biomass after harvesting are found to be suitable substitute for certain fiber based industries. In addition, boiled and washed pretreatment of coconut coir was obtained in fiber … properties suited for a soil erosion control blanket. This article reviews the tensile properties of various plant fibre-reinforced polymers reported in literature. Kolkata: ICAR-National Institute of Research Due to the strong absorption force of the micropores and a high pore volume, the cells retained 929 mAhg-1 with 80% capacity retention of the initial discharge after 100 cycles. Plant fibres can also be regarded as fillers to replace the more expensive polymers and improve the green credentials of the final composite parts. The paper presents the results of an experimental study of bench-scale tests on EICP-treated sands to determine a treatment method feasible for field placement for this application. Cellulose nanowhisker suspensions were characterized by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and X-ray diffraction. In tropical countries where rainfall rates are high, and especially in deforested areas in the Atlantic Rainforest and Cerrado in southeastern Brazil, water is the dominant driving force of erosion. Houve a absorção de 4,3% de água após o período de 2 horas e 9% após 24 horas. As a result, systematic studies of various rainfall intensities are still required. not become bigger as it ages and the soil is less exposed to the action of raindrops. Runoff and soil loss behavior, degradation through tensile strength, and growth of vegetation of the three geotextiles after weather, The end goal of this research is assessing the feasibility of using enzyme induced carbonate precipitation (EICP) to create a cemented top layer to control runoff erosion in sloping sandy soil. We observed that, fiber shrinkage is higher at low temperature and 20% alkali treated coir fibers yielded maximum shrinkage and weight losses. Unlike other syntactic peats, coconut fiber is also a nature-friendly solution for landscaping. (1964). Import of sisal fibre in India is increasing at the rate of 25% per year for last few years. accumulated value (Alvarez-Mozos et al., 2014). O compósito apresenta bons resultados gerando possibilidades de ser aplicado como isolante termoacústico. These batteries delivered an initial discharge capacity of 1233 mAhg-1 at a current density of 200 mAg-1. Despite such wide applications, there are many more avenues where coir and its by-products can be utilized. Jute, Kenaf, Sisal, Abaca, Coir and Allied Fibres Statistics (June). The peak at around 300{sup o}C may be derived from the decomposition and desorption of mercury chloride species. Mechanical and thermal properties of starch/EVOH/coir biocomposites were evaluated. Hume (1949) in his paper mentioned that this short coir fiber is a mass of tiny, brown and irregular shape bits known as coir dust. This research is beneficial for the innovation of acoustic material for interior design and architecture. The Kolmogorov-Smirnov test for goodness of fit. This review summarizes recent advances in the hydrolysis of cellulose by different types of solid acids, such as sulfonated carbonaceous based acids, polymer based acids and magnetic solid acids. that the addition of the coir fiber produced lighter polyurethane foam.

The modified fibers showed significant hydrophobicity, improved tensile strength, and good chemical resistance. This chapter provides an overview of the applications of coir and coir by-products in agriculture, particularly the coir and coir dust as soilless growing media. Sisal is grown in randomly distributed pockets all over Indian sub-continent mainly for some other purpose without giving any attention to the selective variety or species of Agave family. Analyses of the tensile strength of coir fibers showed that after 12 months of exposure untreated fiber had retained 23% and treated fiber 19% of their initial strength. Neste paper foram desenvolvidas placas de isolamento termo-acústico utilizando um resíduo da indústria alimentícia, a fibra da casca de coco, juntamente com um aglutinante. The use of coconut fiber improve the efficiency of soil reinforcement by increasing … The presence of SO{sub 2} during mercury adsorption had an adverse effect on the mercury removal by AC in the presence of HCl. Vegetation cover was monitored by means of a Greenness Cover Index (GCI) computed from photographs acquired weekly during the establishment phase (six weeks) and monthly for the rest of the experimental period. As they are all natural products, their properties not only depend on the plant The fiber surface treated with NaOCl is morphologically similar to the natural fiber surface, have the element Cl on your surface and it is a little more hydrophilic than the natural fiber. The fruit is harvested from palm trees and later processed to produce several food and aesthetic products that bear considerable health benefits. The effect of successive removal of lignin and hemicelluloses on the fine structure has also been studied. suggested by DOST-PTRI and the diameter was patterned after, Existing vegetation were trimmed down for easier installation of. Looking into the vast quantities of waste biomass of banana plant available in the form of its pseudo stem and the potential applications of fiber obtained, the present study was taken up to explore the possibilities of improving the quality of machine extracted banana fiber with the help of commercially available pectinases. Considering that lime treatment improved coir fiber properties, lime applications are indicated when coir geotextiles are to be used in acidic Brazilian Cerrado soils. Treated fibers were incorporated in starch/ethylene vinyl alcohol copolymers (EVOH) blends. The percent moisture regain, tensile strength, and behavior toward some chemical reagents (solubility %) of parent and chemically modified fibers have also been evaluated. Among them, banana is one which yields high biomass that may serve as an alternative source in fiber based industries like paper, card board, tea bags, fiber lining for car interiors, high quality dress material, currency notes etc. Changes in moisture regain, crystallite orientation, and percentage crystallinity were observed when fibers were treated with hydrochloric acid (10%), sodium hydroxide (10%), and acetic acid (10%). The use of heterogeneous solid acids can solve some of these problems through the ease of product separation and good catalyst recyclability.
