Fibre materials, as thermal insulation materials, will be an optimum choice for inflatable mini cold storage. The evaluation index such as infrared spectrum, thermal stability and thermal conductivity is closely related to the selection and application of fibrous insulation materials. The results showed that the transmittance of bamboo fibre tested by Fourier Transform Infrared Spectroscopy (FTIR) measurements was about 35.3% with an advantage to the heat preservation, and radiation heat transfer was analyzed in the area of far-infrared. The initial decomposition temperature of 1#, 2# and 3# measured by TGA curve was respectively 383.9°C, 372.5°Cand 315.4°C, and the total thermal weight loss rate of 1#, 2# and 3# was 64.59%, 90.16% and 80.47%. The thermal conductivity of 1# at 0°C was 0.035 W·m-1·K-1, lower than 2# and 3#, also lower in the temperature range from 0°C to 8°C, measured by hypothermia thermal instrument.
