Title: Express Evaluation of the Thermal Insulation Properties of Bulk Non-Woven Textile
Keywords: air permeability, nonwoven textiles, thermal conductivity, thermal insulation

Abstract: Polyester nonwovens are widely used in civil engineering for thermal insulation, highlighting the importance of understanding how structural factors affect thermal properties. This study utilizes thermal imaging to experimentally investigate the thermal characteristics of 'Struto' nonwovens. Eight samples of 'Struto' nonwovens were selected for analysis of thermal conductivity, with external surface temperature maintained at a constant 40°C. The research focuses on exploring the relationship between thermal conductivity and air permeability, crucial aspects of the material's structure. Findings show that 'Struto' nonwovens with greater thickness and higher density offer superior thermal insulation performance. Furthermore, the study underscores the potential of Stratex Comfort L-B 1400, a non-woven textile material manufactured in Bulgaria with a low thermal conductivity coefficient of 0.0363.
