High yield planting method of sisal

Abstract: The invention discloses a high yield planting method of sisal, which achieves the high yield of the sisal through the steps of land deep ploughing and leveling, field planting, shallow tillage and weeding, pest control, fertilization management, leaf harvesting and the like. The sisal planting method has a more obvious effect on improving the yield of the sisal. The method is superior to a prior ratio method in the number of leaves per plant, the lengths of leaves, the yield per mu per year, the fiber strength and other aspects, the reason is that the method can provide sufficient nutrients for sisal growth, an important organ for nutrient absorption of sisal is leaves, therefore, using leaf fertilizer and additionally applying fertilizer after the harvesting have a remarkable effect on the leaf surface growth of the sisal, and the sisal fiber has higher quality.

Tensile Properties of Natural Fiber-Reinforced Epoxy-Hybrid Composites

Abstract: A study has been carried out to investigate the tensile properties of composites made by reinforcing sisal, coconut spathe and ridgegourd as the new natural fibers into epoxy resin matrix. The natural fibers extracted by retting and manual processes were subjected to alkali treatment. The composites fabricated consist of reinforcement in the hybrid combination like sisal-coconut spathe, sisal-ridge gourd and coconut spathe-ridge gourd with the weight fraction of fibers varying from 5% to 30%. It has been observed that the tensile properties increase with the increase in the weight fraction of fibers to certain extent and then decreases. The hybridization of the reinforcement in the composite shows greater tensile strength when compared to individual type of natural fibers reinforced. For all the composites tested the tensile strength of the composite increased for approximately 25% of weight fraction of the fibers and further for the increase in the weight fraction of fiber the strength decreased, also it is found that for the hybrid combination of ridge guard and sisal fibers there is 65% increase in the tensile strength.

Investigation of Fiber-Based Bag Filter Coated with Metal Oxides for Dust Adsorption

Abstract: The production of cement increases every year, which leads to the emission of dust/gas/ particulate matter. The emission of unfiltered dust would create a significant environmental impact. Hence, it is the responsibility of industries to control the emission of dust. Air filters and electrostatic precipitators (ESP) play a significant role in controlling pollutants. Synthetic filter media which are dangerous to our environment are widely used in most industries. The disposal of synthetic filters is an arduous task as the biodegradability of synthetic materials is poor. Hence, it is essential to develop an eco-friendly air filter material. In this paper, a new type of bag filter was designed by using natural sisal fiber as filtering media. The biodegradability of sisal fiber is better than the synthetic polyester media and also sisal fiber is less expensive. The natural fibers were coated with zinc oxide and iron oxide nanoparticles to improve the dust adsorption rate. Various tests were conducted as per standards to validate the performance of the filler media. The results were impressive. Hence, the proposed sisal fiber-based filter media can be used in cement industries for dust adsorption to minimize the environmental impact.

Use of Sisal Fiber and Cement to Improve Load Bearing Capacity of Mud Blocks

Abstract: Using soil as a construction material for masonry works have been indigenous technology. The present research investigates on use of sisal fibres and cement additives to enhance compressive strength of properties of mud block to advance traditional native knowledge and meet current construction material standard qualities. An experiment with total of twenty-four mixes consisting of 96 blocks was designed with mixes of 0% to 15% cement; 0% to 1.25% sisal fiber proportional to clay soil dry mass. At 28 days, compressive strength and density tests were performed as per ASTM standards. Test results showed use of sisal fibers and cement increased compressive strength of mud blocks up to 210.1%. Optimum mix design for enhanced mud block compressive strength performance were 10% cement and 1% sisal fiber composition.
