Abstract:
In order to obtain silk fabric with good flame retardancy, silk fabric was finished with boron phosphate doped silica silica sol by pad -dry-cure process. The surface morphology, flame retardant properties and element distribution of the silk fabrics were tested and characterized by scanning electron microscopy, oxygen index, energy spectroscopy. The results show that the silk fabric finished by immersing silk fabric in the doped modified silica sol and drying 170 °C for 3 min has best flame retardancy, and the doped modified silica sol was prepared from 100 mL of silica sol, 50 mL of deionized water, 30 g/L of boron phosphate, 50 g/L citric acid, 40 g/L of tartaric acid, 45 g/L of sodium phosphinate by stirring at 80℃ for 3 h. The limit oxygen index of silk is 30.6% and has good washing durability.
Key words: sol-gel process, silk fabric, flame retardancy, boron phosphate
