A Study on the Thermal Stability of Carpet in Air Condition

This paper describes the experiments for investigating the effects of thermal stability of several commercial carpet mate materials. The melting point and thermal decomposition temperature was measured by means of a differential scanning calorimeter(DSC) in air condition. The DSC data and burning test results of nylon bulked continuous filament(N-BCF) yarn 100%, nylon(NY), polypropylene(PP), and a new material named polytrimethyleneterephthalate(PTT) were analysed to obtain the effect on their thermal stability. Conclusively, we observed that PTT and PP were approximately 380^{circ}C and 240^{circ}C to start the thermal decomposition, respectively. In other words, PTT is thermally the most stable material for carpet manufacturing.
