- Annotation: The article presents a comprehensive analysis of the thermophysical and operational properties of highly porous thermally bonded polyester-based nonwovens to justify their use as an effective functional layer in multifunctional removable and detachable thermal protective coatings for pipeline systems. Laboratory tests of samples of nonwovens with different surface and bulk densities have been carried out. Their effective coefficients of thermal conductivity are determined. An approach to a fibrous material as a continuous porous medium is used to model heat transfer. The heat resistance and parameters of the insulating layer are calculated according to classical methods for multilayer walls. It has been established that nonwoven fabric has elasticity, shape stability, ease of installation, UV resistance and safety.It has been scientifically proven that polyester-based highly porous nonwovens present a highly efficient, technologically advanced and durable alternative to traditional insulating materials (e.g. mineral wool) for creating energy-efficient thermal insulation coatings. The calculated dependences obtained make it possible to optimise the design of thermal insulation structures.
