Development of Airlaid Non-woven Panels for Building’s Thermal Insulation

This study aims to explore a textile technology using Airlaid process to develop non-woven fabrics made of natural fibers extracted from Posidonia Oceanica’s waste for assessing their suitability for insulation products in the construction field. The prepared panels are analyzed for their thermal conductivity which were close to commonly used thermal insulation materials, ranging between 0.03515 W/m.K and 0.03957 W/m.K. The second part of this work aims to determinate the panel's resistance to five common mold types in buildings. In fact, at high moisture content, molds are likely to develop on cellulosic materials affecting indoor air quality and eventually causing a variety of health risks to occupants. However, optic microscope results showed no growth of molds on the Posidonia samples which allows conceiving reliable thermal insulation materials.
