For instance, Mohamad Jani and Rushdan (2014) have successfully produced bleached paper from coir fibers using a chemi-mechanical pulping process. Paper also is one of … Given the increasing global demand for pulp, there is a need to look into the prospects of increasing fiber production and shortening the harvesting cycle of abaca without sacrificing the quality of fibers for pulp production. This study was to investigate the suitability of coir fibers as an alternative material in making pulp and paper. All pulp was completely prepared by using mechanical pulping and the raw materials are coir fiber and newspaper. The effects of beating on the characteristics of pulp and paper derived from durian rind under chemi-mechanical pulping (CMP) method were investigated. Recycled pulp of old corrugated containers (OCCs) was studied as a possible fiber source for wood-fiber cement (WFC) sheets. Making your own paper gives you control over the final color and texture. In this study, fiber-paper was successfully done and the effect of different coir fiber percentages with different beating times was been compared based on its mechanical properties. Coir is a byproduct of the coconut industry. The fiber length of 1.76 mm was observed, … Thus, WFC sheets were made using less costly OCC fibers utilizing various types of treatments including fiber fractionation (FF) … The utilisation of coir fibre can create economic and environmental advantages. Fiber Properties The ability of coir fibers as raw material for pulp can be determined by measuring the fiber dimensions that contribute to the strength properties of the pulp. This study investigated the chemical and pulp properties of abaca cv. Maize husk and stalk were assessed for their fibre characteristics and suitability for pulp and paper production. In pulp and paper manufacture, silica present in fibers (3% to 14% in rice and wheat straw) accumulates and causes scaling in evaporator tubes, reducing the efficiency of the pulping process . There have been relatively few reports on the usage of coir fibers as an alternative raw material for pulp and paper products. Maceration process was used to characterize the fiber. It was observed that fibre length of maize husk was 1.37mm and that of maize stalk was 1.52mm. Coconut fiber, or coir, adds further texture to the paper. The paper can then be used in a variety of projects including card making, scrapbooking and paper art. The coir fibre pulp was chemically analysed; pulped by chemical-mechanical pulping (CMP) process and bleached by … Fifteen (15) fibres were randomly selected and measured from each representative sample. Soda-AQ pulping with various combinations of active alkali (18-22%) and cooking time (90-150 minutes) at fixed temperature was done. Sorghum halepense, one of the fast-growing highly unpalatable grass species with high biomass, was evaluated for its fiber properties to be used as an alternative raw material for pulp and paper production. FAO 2009 Rowell and Cook classify the potential sources of non-wood Year Book on Forest Products 2005-2009 revealed that during fibers for paper production into three groups that are: (1) crop this period the average non-wood fibers pulp account for 11% residues from point source processing centers, (2) food crop of the total world pulp … The purpose of this study was to identify whether the coconut coir can be replaced wood as the main material to produce paper in the future. Fiber dimensions and derived values of coir fibers and the relevant data from the literature are summarized in Table 1. The potential availability and economics of using agro-based fibers far outweigh their limitations. Physical properties … All process and characteristic tests were conducted according to Malaysian International Organization for Standardization (MS ISO) and Technical Association of the Pulp and Paper … Inosa fibers harvested at different stages of stalk maturity to determine their suitability … This industry currently largely relies on kraft pulp, an expensive fiber source. Conclusions. The fibre diameter (D) was 30.19 μm … Paper and paper-based products are important in our lives. The fiber properties were compared with other wood and nonwood fibers.
