KINETIC AND THERMOGRAVIMETRIC ANALYSIS OF THERMAL-DEGRADATION OF POLYCHLAL FIBER POLYESTER FIBER BLEND

The flammability behavior of a series of polychlal fiber/polyester fiber blends has been investigated in terms of the oxygen index and the thermal degradation characteristics. The thermal degradation behavior of these fiber blends has been studied by a conventional dynamic thermogravimetric technique in a flowing air atmosphere at several heating rates. Quantitative data are presented that pinpoint how the flammability behavior of the blends differs from that of the components. These results indicate that interactions occur between the polychlal and polyester fibers in the blends.
