Enhancement of coir fiber fire retardant property

Application of porous material in acoustic panel has shown its effectiveness to control noise in term of sound absorption. optimizing synthetic fiber as resource in current market contributed several issues related to the depletion of environment. hence,engineer has turned to natural fiber from agriculture waste as alternative strategic solution. despite having certain beneficial properties in acoustical field,to fulfill the building standard,property of fire retardant are yet to be implemented. this study has focused on three potential fire-retarding chemicals on coir fiber,namely,di-ammonium phosphate (dap),borax and urea. vertical burning experiment was executed based on standard of astm e69–02 (standard test method for combustible properties of treated wood) using fire-tube apparatus prior to chemical treatment. based on experimental results,dap,borax and urea-treated fiber shows mass loss of 6.67%,7.60% and 9.48% respectively. compliance with nfpa 704,dap was shown to exhibit superior ability to retard fire in coir fiber over other additives based on mass loss and low degree of hazards in terms of health,flammability and reactivity. in conclusion,fire retardant chemical like dap is an essential component to be improved on to bring about the success commercialization of the acoustic panel. © school of engineering,taylor’s university.
