Thermo physical characterisation of recycled textile materials used for building insulating

A recycled textile materials were thermo physically characterized in terms of thermal conductivity and diffusivity. Two samples waste linter (WL) and tablecloth (WT) were produced by shredding and mixing. Thermal conductivity and diffusivity were experimentally determined by means of the Box Method equipped with a flash. The Parker equation and Degiovanni equation were used to evaluate the thermal diffusivity. Studied properties were compared to other usual building insulating materials. Results show that the thermal conductivity of WT and WL were 0.033 W/mK and 0.039 W/mK, respectively. In addition, the thermal diffusivity was found to be about 5.8×10−3 m2/h in the case of WT and about 3.8 m2/h·10−3 for WL sample. Therefore, the recycled textile materials have competitive thermal properties and could be used in the building insulations materials.
