Mohair is one of the most luxurious and best quality natural fibers. Recent developments focused on expanding the use of mohair in technical and functional textile products. It necessitated the need for an improved understanding of how the usage of mohair in fabrics will impact its thermal comfort related properties. Despite its popularity, little information is available on the quantification of thermo-physiological comfort properties of mohair fabrics. This study investigated the effect of fibrous matter composition and fabric structural parameters on conductive and convective heat transfers to study the thermal comfort properties of mohair fabrics. The results showed that fabric structural properties such as overall porosity, and specifically thickness, played a significant role in determining the thermal comfort properties of the fabrics. Fiber composition had an impact on thermal properties as the fabrics containing mohair or mohair/wool were consistently thicker, providing higher thermal resistance as well as resistance to the free flow of air that allows thermal convection. It may be concluded that the thicker structures of mohair or mohair/wool trap more air, providing higher thermal insulation.
