A novel formaldehyde- and halogen-free coating, containing phosphorus, nitrogen and silicon, was synthesized with a promising approach to enhance flame retardancy of cotton fabric. To this aim, a new sol-gel precursor, comprising in the same molecule P, N and Si, namely (3-Glycidyloxypropyl triethox...
