However, TPCS have some limitation such as poor mechanical properties. Edible parts of Cogongrass: Young inflorescence and young shoots - cooked. Cogongrass is a perennial grass that varies greatly in appearance. The links that are shown are not an exclusive listing of organizations available within the state. The influence of cooking variables on the soda and soda-ethanol pulping of Nypa fruticans petioles is evaluated. Non-woody plants are potential sources of raw material for pulp and paper and supplement the depleted wood fibre resources. To investigate the natural frequency and mode shape of thermally stressed plate by using Functionally Graded Materials (FGM). For ash content, CG produced a value of 7.80 %, not much different from the literature of 8.24% reported by Kassim et al. The differences in microstructure, crystalline structure, and mechanical performance of these two kinds of cellulose aerogels were studied and compared. The chemical compositions, fibre dimension, pulp and mechanical properties of I. cylindrica were investigated for application in paper-based production. Cogon grass grows 0.6–3 metres (2–10 feet) tall and has roots that can reach more than 1 metre (3.3 feet) long. Because of the large geographic area infested with cogongrass and the often economically and environmentally unacceptable management techniques, biological control organisms also should be researched. The leaves originate directly from ground level and range from one to four feet in length. The chemical composition of the kenaf bast and core fibers, and also whole stalk with different growing time were examined prior to pulping attempts. On the fiber surfaces, areas with different microfibrillar orientations were found. Although cogon grass contains short fibres length than oil palm leaf, the paper product will have higher strength due to the good inter-fibre bonding. . Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. The aim of this study was to bleach pulps to high brightness, while retaining sufficient strength properties. ... Table 1 presents some physical and chemical properties of CG. In the past, cogon grass has been researched as an adsorbent for removal of heavy metals [9] and dyes [10] from water/wastewater. Duplicate License For Agencies, Schools and Individuals licensed under Chapter 493 F.S. SEM images show that cogon grass fibres contained abundance and long fibres which provide good strength of the produced handsheet. 1. Accessed on November. The results of the physico-chemical analysis were within the range of those reported elsewhere for some non-woody pulping raw materials except solubility in cold and hot water was higher. approximately 3 million metric ton in 2007 (Goya, to the environmental concerns and resources depletion, grass that is distributed worldwide in the tropical and, Pahat, Johor. The number of vascular bundles per mm 2 was maximum in Imperata cylindrica and minimum in Phragmites karka. The holocellulose and alpha-cellulose in tobacco stalks were lower than those of hardwoods and common nonwoods. At this stage, the leaves lack sharp points and razor-like leaf margins. Peroxide reinforced oxygen (PO) and hydrogen peroxide (P) were used in the TCF bleaching of different fractions and blends of kenaf kraft pulps. Some combinations of herbicide, discing, and revegetation with desirable plant species provide excellent control. Due to its short growth period, high yield and comparable physical and optical properties, kenaf is a viable and attractive non-wood fibre source alternative for soft- and hardwood fibres. Young infestations are usually easier to control than older well-established infestations. INTRODUCTION. The brightness of pulp made by tobacco stalks reached about 73.06% on DED and 78.2% on DEDD bleaching sequences. Revised/Replacement License For Agencies, Schools and Individuals licensed under Chapter 493, F.S. Oil retention experiments reveal the good ability of cogon grass to hold oil with about 96% retention after 24 h dripping. In addition, lignin content of tobacco stalks was lower than that of hardwood. Cogon grass (Imperata cylindrica) is an invasive, non-native grass which occurs in Florida and several other southeastern states.
