Bifacial fabrics were produced on a purpose-built machine, using wool, acrylic and polyester yarns, with the woven structure being plain weave, and the knitted structure being single jersey. In this study, the heat transfer properties of these fabrics were compared with conventional woven and knitted fabrics. The bifacial fabrics had lower air permeability than knitted and woven fabrics, and they were warmer to touch. The thermal resistance of the bifacial fabrics was higher than the knitted and woven fabrics, and the thermal resistance of the two faces of the bifacial fabrics was statistically different.
