Studies on some flame retardants for cotton

摘要

Two organophosphorus compounds namely, triethylaminophosphine oxide and tri-(N-ethyl-N-hydroxymethyl) phosphine oxide were synthesized and their structures were confirmed by elemental analysis, IR, NMR and mass spectroscopy. Tri~ (N-ethyl-N-hydroxymethyl) phosphine oxide was applied to the cotton fabrics using pad-dry-cure method. The finish fabrics were monitored for nitrogen content, phosphorus content, andflammability. The prepared compound was successfully used as flame retarding agent. Better results are obtained with finishing formulation tri-(N-ethyl-N-hydroxymethyl) phosphine oxide, 7.5g/L NH_4Cl and 200 g/L trimethylolated melamine, using pad-dry-cure method, curing at 1601℃ for 10 minutes.
