Abstract: The development of breathable and thermal comfortable textile materials is of increasing significance for personal thermal comfort products. In this study, graphene-coated sheep wool, goat wool, and sheep wool/goat wool composite fabrics were developed and their moisture management properties were evaluated according to ISO 11092. Water vapor permeability (PWVP) and water vapor resistance (Ret) were measured to assess the breathability performance of the fabrics. The results revealed that the graphene-coated sheep wool fabric exhibited the highest water vapor permeability (36.60%) and the lowest water vapor resistance (5.96 Pa·m²/W), indicating superior moisture transport capability. The graphene-coated goat hair fabric showed the lowest permeability (28.43%) and the highest Ret value (9.80 Pa·m²/W), while still remaining within the "good breathability" category. The graphene-coated sheep wool/goat hair composite fabric demonstrated intermediate behavior with a PWVP of 35.10% and a Ret value of 7.80 Pa·m²/W. According to ISO 11092 comfort classification, all investigated fabrics can be considered breathable materials.
