This study explores the potential application of blast furnace slag(BFS) for synthesizing hydrotalcite-like compounds. The CaMgAl-HTLcs were synthesized and characterized by XRD, SEM, BET and laser particle size analyzer. The altered parameters (pH value, titration way and sonication) were investigated to optimise the synthesis procedures. The CaMgAl-HTLcs was incorporated in the cotton textiles to improve its thermal stability. Thermal properties and flame retardancy of the composites were studied by thermogravimetric analysis, differential scanning calorimetry. The thermal degradation results showed that the addition of 6 wt% of the CaMgAl-HTLcs resulted in a substantial increase in the thermal stability and a reduction of the heat release rate, heat release capacity and total heat release.
