Insulation Characteristics of Fabric Assemblies

This research was conducted to assess thermal transmittance and air permeability of selected textile fabrics in single and multilayer configurations Fabric geometry was found to contribute significantly to both the thermal transmittance and the air permeability of the assemblies. Fabrics representing a range of fibers, yarn structures and fabric constructions were used to develop model textile assemblies which op-timize thermal transmittance and air permeability. The findings of the study provide an understanding of the insulation performance of textile fabrics and fabric assem-blies in a variety of applications, ranging from apparel to thermal insulation used in buildings
