Abstract: A series of non-woven fabrics were fabricated by blending 50-80wt% of thermoregulated fibres containing n-eicosane, n-nonadecane or n-octadecane with 0-40wt% PET fibres and 0-20wt% PP fibres. The phase change properties, thermal conductivity, thermal resistance, heat flux and inner temperature difference between wool felt and the thermoregulated non-woven fabrics of the non-woven fabrics were measured respectively. The thenno-regulated non-woven fabrics absorb heat at 25-34°C and release heat at 10-25°C. The measured highest enthalpy of the non-woven is approximately 18 J/g. During a heating process, heat flux of the non-woven fabrics is composed of three parts: heat absorbed by the cold textile touching the hot plate, heat transmitted from the hot plate to the cold plate, and the heat absorbed by PCM from the hot plate during the phase change process. The measured maximum inner temperature difference in a temperature rising process between the wool felt and the thermo-regulated non-woven fabric is approximately 8°C. The inner temperature difference (Tr-Ts > 0) lasts 16-45 min. By contrary, the measured maximum inner temperature difference in the temperature decreasing process is approximately -6.5°C. The inner temperature difference (Tr-Ts < 0) lasts 16-50 min. The temperature regulation properties are obviously observed.
