AB - Wool fabric was treated with silica sol and phosphorus doped silica sol by  sol-gel method in order to improve its thermal properties and flame  retardance. The thermal stability, combustion behavior, and smoke suppression  of the control and finished wool fabric were analyzed using thermogravimetric  analysis, limited oxygen index, micro combustion calorimeter, and smoke  chamber. The results showed that wool fabric treated by phosphorus doped  silica sol had excellent thermal properties and flame retardance with higher  final char residue and LOI value. Furthermore, heat release rate and smoke  density results indicated the safety performance of the treated wool fabric  on fire.
