Fibrous Insulation

Abstract As known, many multi-purpose plants can be used in different industries. This research is focused on the possibilities to utilize hemp as feedstock for thermal insulation products. The most advantageous features of hemp insulation are associated with health and environmental safety. The thermal conductivity of commercially available hemp insulation products is comparable with that of other fibrous insulation materials; however, it is possible to develop new products that could be more efficient in terms of cost and due to other important features.

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.

Hemp Fibres

Natural fibres from flax and hemp are used as raw materials for efficient thermal insulation. In current work, tests were carried out using chopped and combed long flax fibres as well as chopped and combed long hemp fibres. Investigations have shown that thermal conductivity of natural fibres depends on their preparation method (combing, chopping) and materials density.
