The effect of heat on wool and wool treated with Zirpro by X-ray photoelectron spectroscopy

Thermogravimetric analysis and differential scanning calorimetry in combination with X-ray photoelectron spectroscopy, have been applied to the study of degradation of wool and its flame retardation after treatment with Zirpro. ZrOF 2 is of importance in flame retardation and smoke suppression, the latter depending mainly on the contribution of covalent linkages in Zirpro flame retardant.
