Summary: | PURPOSE:To improve safety to fire by a method wherein a heater and a temperature detecting end are held firmly by a heat-bonding fiber structure body made of a thermoplastic polymer having a specific melting point and further a knitted fabric or web of non-fusible organic synthetic fibers having a specific decomposition temperature is laid on the opposite outside surfaces of the heat-bonding fiber layers. CONSTITUTION:This electric carpet structure has a construction wherein a heater and a temperature detecting end are held firmly by heat-bonding fibers made of a thermoplastic polymer having a melting point of 200 deg.C or above and wherein a fiber layer being non-fusible and excellent in thermal characteristics is laid on the opposite upper and lower surfaces of layers of the heat-bonding fibers. The non-fusible fiber layer is provided for holding back the lowering of performance due to refusion of the heat-bonding fibers and the lowering of viscosity thereof when an electric carpet is heated to a high temperature by an abnormal rise in the temperature of the heater or some trouble brought about from outside, and a material having a thermal decomposition temperature of 450 deg.C or above and being non-fusible, a knitted fabric or web of fibers made of a polybenzazole polymer suitably, is used therefor. |
