Phosphorus-nitrogen Synergism and Their Thermal Behavior of Vinyl Phosphonate Oligomer-NMA Treated Cotton Fabrics
Vinyl Phosphonate Oligomer-NMA 처리 면직물에 있어서의 인-질소상승효과와 처리직물의 열적성질
Abstract
Phosphorus-nitrogen synergism in vinyl phosphonate oligomer (Fyrol 76) and N-methylol-acrylamide (NMA) treated cotton fabrics was studied through LOI and char length. And their thermal behavior under inert gas was also investigated through DSC, TGA and GC. When the total content of flame retarding element P and N was held constant, the maximum synergistic effect was observed at the P to N ratio 7:3-6:4. The DSC curves for Fyrol 76/NMA treated cotton fabrics under nitrogen atmosphere show an exothermic peak and two endothermic peaks. The second endothermic peak which is due to the decomposition of cellulose shifts 50-60
