Thermal Insulation of Single and Multiple Layers of Fabrics

Thermal insulation, thickness, and volume of air per unit area of fabric have been determined for single and multiple layers of fabrics. A comparison of the thermal in sulation and thickness values obtained by the actual measurement of multiple layers of fabrics to those obtained by adding the values of the individual fabrics involved has been made. In addition, thermal insulation data for the single and multiple layers of fabrics were plotted against the values for the other properties to show the relationships that exist.
