Pyrovatex breakdown before textile valorisation

Yasin et al. (2017) demonstrate that the permanent PIN FR textile treatment Pyrovatex CP (based on N-methylol dimethyl phosphonopropionamide MDPA) can be decomposed, to allow thermal valorisation of recovered PIN FR textiles. Testing used virgin cotton textiles, treated with the FR. The FR decomposition process used advanced oxidation (Fenton’s reaction), by application of an iron source (iron sulfate FeSO4) and hydrogen peroxide catalyst at room temperatures, followed by sodium hydroxide quenching and drying. Valorisation tests of textile pellets in a gasification unit showed that syngas production from FR textiles after the Fenton’s treatment was similar to that from non FR treated textile.
