Natural fibers have been good substitute sources for swapping synthetic fibers and reinforcing polymer matrices because of their contributions in maintaining ecology, low energy requirement for processing, and maintaining sustainability issues. e aim of this study was to characterize a new fiber from Cyperus Dichrostachus A.Rich (CDA) plant. e CDA plant is a perennial nonwoody grass found in Ethiopian high lands and river basins. e fiber from this plant has a chemical composition of cellulose (60.27%), hemicellulose (22.72%), and lignin (16.59%) contents. It has a density of 1010 kg/m 3 and good tenacity of 105.76 cN/Tex with low elongation of 4.88%. e thermal stability of Cyperus Dicrostachus A.Rich fiber (CDAF) was studied using TGA and DTG analyses and revealed that the cellulose degraded at a temperature of 377.1 ° C. Fourier transform-infrared spectroscopy analysis confirmed that CDAF is rich in cellulose content. Additionally, CDAF can play a vital role as a new reinforcement material and best alternative in bio composite industries. is will give competitive advantages when evaluated with other natural fibers and reveal that there are significant potential benefits in implementation of “cleaner production” in textile material production industries. Specifically, the replacement of synthetic fiber source with renewable biomass will reduce the envi- ronmental impact of these fibers. e future study will be focused on investigating the possible valorization route, especially in paper board, composite reinforcement, and bio composite applications. 1. Introduction It has been obvious that numerous natural plants have been grown in different parts of the world, grown in agricultural domains, and after their lifetime, end up in landfills [1, 2], some other plants grow in the wild and spread around forest areas like CDA by their nature, some possess pharmaceutical properties, and others yield edible parts [3]. Currently, perhaps, there have been many research works being put out which use natural fibers in different application areas. Most research works propose the use of plant fibers as reinforcement in polymer matrices, home furnishings, and construction industry. ey have also been utilized even in apparel manufacturing applications. For this reason, it is necessary to study and characterize the natural fibers in order to add value on their current applications. Nowadays, new natural fibers [4–11] for multidisciplinary applications in reinforcements [12, 13], automotive engi- neering, and packaging applications are utilized. Starting from the 1980s, several natural fibers [14] in- cluding coir [15, 16], sisal [17–20], pineapple [21–24], jute [25–28], hemp [29, 30], palm [31–33], banana [34–37], and other fibers have been characterized and employed in many applications, for example, in reinforcement of polymer matrix in composites. Ethiopia can nurture a diversity of naturally fiber- forming plants. One of the most common plant that is currently grown commercially and could be of interest for handcrafting, packaging, and traditional equipment is Cyperus Dichrostachus A.Rich) plant (CDA) [38–41]. It is a tough plant, traditionally used for the weaving of shelters, mats, and baskets in Ethiopia and a number of countries in Hindawi Advances in Materials Science and Engineering Volume 2022, Article ID 4868809, 11 pages https://doi.org/10.1155/2022/4868809
