Borate, as a multifunctional material that is a flame retardant, smoke suppressant, afterglow suppressant and electrically resistant, was synthesized on viscose rayon felt using surface modification reactions. In addition viscose rayon phosphate was also synthesized for a comparison test. All reactions were confirmed by ATR FT-IR and TOF-SIMS. The thermal properties of the synthesized viscose rayon borates were investigated using a thermogravimetric analysis and calculated activation energy using the Freeman and Carroll method. The optimal reaction temperature of the synthesized viscose rayon borate was found to be 350 °C. Oxygen index and volumetric resistance rate tests of viscose rayon borate were conducted for flame retardency and electrical resistance, and compared with viscose rayon phosphate. The synthesized viscose rayon borate showed excellent physicochemical and thermal properties, and was found to be a highly effective flame retardant and electrically resistant.
