文摘

A recycled textile materials were thermo physically characterized in terms of thermal conductivity and diffusivity. Two samples waste linter (W_L) and tablecloth (W_T) 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 W_T and W_L 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 W_T and about 3.8 m²/h·10⁻³ for W_L sample. Therefore, the recycled textile materials have competitive thermal properties and could be used in the building insulations materials.
