Abstract

The pure silica hydrosol and phosphorus-doped silica hydrosol was prepared using sol-gel method with methyltrimethoxylsilane(MTMOS) and tetraethoxysilane(TEOS) as precursors and ammonium biphosphate as a flame retardant(FR) in the presence of hydrochloric acid and cationic /nonionic surfactants in aqueous solution. Then the synthesized sol was modified by hexadecyltrimethoxysilane(HDTMS) and applied to cotton fabric to endow the fabric with flame retardancy and low surface energy. The effects of different conditions on flame retardancy and hydrophobicity of cotton fabric were discussed. The factors about dosage of precursors and FR, the ratio of surfactants, pH were determined. The Limited Oxygen Index (LOI), contact angle (CA) test and thermogravimetric analysis were used to indicate differences between treated and untreated cotton fabrics. The results show that the phosphorus-doped silica coating is helpful to improve the flame retardancy and water repellence of cotton fabrics.
