STUDY OF SYNERGISTIC FLAME RETARDANCY OF PHOSPHORUS AND BORON ON COTTON AND COTTON-PET BLENDS FBRICS

The fire retardancy effectiveness of mixtures formed from phosphorus-containing compound and boron-phosphorus-containing compound were examined utilizing limited oxygen index (LOI) and vertical test techniques. Phosphorus-boron systems in flame retardancy may show synergism and antagonism. The fire-retardancy effectiveness of boron-phosphorus-containing compounds are superior to the mixing systems of compounds which contain phosphorus or boron individully.     

STUDY OF FLAME RETARDING FINISH OF POLYPROPYLENE / VISCOSE BLEND FABRICS

The combustion mechanisms of PP / Viscose blend fabrics are briefly discussed, and the factors affecting flame retarding(FR) effect are analyzed. Apart from this, the choice of processes of FR finish is also discussed in this paper. Other factors such as coating add-on, curing temperature and time are studied too. The results show that the factors above all have different extent of influence upon FR effect.
