Abstract
The growing need for sustainable and environmentally friendly materials across various sectors has generated an increased interest in the extraction of bamboo fibres. The primary objective of This study is to tackle the obstacles linked with bamboo fibre extraction and analyze the effectiveness of sodium hydroxide (NaOH) solution in improving the quality of the extracted fibres. The endeavour was initiated to analyze the historical progression of bamboo fibre
extraction techniques, the significance of chemical treatments in fibre processing, and the specific impacts of NaOH treatment on fibre characteristics. The study encompassed an extensive review of pieces of literature to comprehend the context and importance of bamboo fibre extraction, encompassing both conventional techniques and contemporary advancements. The experimental arrangement for distilled water and NaOH treatment was formulated, encompassing variables such as concentration fluctuations at 5%,
10%, 15% and 20% NaOH. The weight of water used was also calculated to be 1000g, 950g, 900g, 850g, and 800g to form solutions respectively. The Fourier Transform Infrared (FTIR) spectroscopy was applied to investigate the chemical structure of fibres before and after treatment, providing important details on the success of the extraction method. Data collection techniques involved sample preparation, maintenance of controlled environmental conditions,
and statistical evaluation of experimental findings.
The outcomes showed that NaOH treatment efficiently dissolved lignin, cellulose, and hemicellulose constituents from the bamboo fibres, resulting in purer and cleaner fibre outputs. FTIR analysis corroborated the partial elimination of non-cellulosic components, with heightened NaOH concentration correlating with increased removal of lignin and hemicellulose. The discoveries from this investigation enhance comprehension of the chemical composition of
bamboo fibres and underscore the potential of NaOH treatment in refining extraction processes. Additionally, the implications of the outcomes for industrial utilization, alongside suggestions for
future research, are comprehensively deliberated
