For the purpose of flame retardation, nylon 6 textile was first hydroxymethylated and then the methylol group containing nylon 6 textile was finished with Pyrovatex CP at 160–170°C. The limiting oxygen index (LOI) value increased from 23.6 for the original textile to 31.4 for the modified one. The mechanism of flame retardation was investigated using thermogravimetry (TGA), differential scanning calorimetry (DSC), elemental analysis, infrared spectroscopy, and X‐ray diffraction. Results reveal that Pyrovatex CP plays a flame‐retarding role in both the condensed and gas phases.
