This study focus on the insulating thermal properties of an insulating composed of textile waste in order to exploit the many advantages by the implementation of such material: matter gain, environmental and ecological advantages, creation of job sites and finding a new field of exploitation of recycled textile waste.
In this work, we have used two structures of textile waste samples comminuted: Textile linters of waste, “WL”, and a tablecloth of textile waste, “WT” to insulate the building by blowing or by recovery. This paper describes the results of research of hydrous behavior of such support and its impact on thermal properties, in particular, the diffusion coefficient of water vapor, the kinetic absorption, the moisture uptake and its effect on the thermal conductivity. Compared with other insulators, they present competitive thermal properties: Their conductivities varied between 0.033-0.059 w/mK for tablecloth and 0.039-0.063 W/mK for the linters respectively, when the relative humidity varies from 50% to 90%. Spite of their loss of insulation ability with increasing relative humidity, they could be considered, always, as civil construction insulation materials. They react rapidly to absorb a considerable rate of humidity (15.5% for the Tablecloth and 23.6% for linters of their dried weight), so moderate the climate by capturing the excess of moisture. Their diffusion coefficients of water vapor
