The natural colored cotton provides environmentally-friendly and cheap products. Because the elimination of dyeing process it is possible to save up dyeing and some finishing costs. Angora rabbit fiber is a specialty animal fiber with good softness, brightness, fine-ness and warmness. To produce healthy, ecological and warmer products, these two fibers should be blended. In this study, to produce ring-spun yarns, natural colored cotton and Angora rabbit fibers were blended with different blend ratios. Then, double face fabrics were knitted. On the front side of the fabric natural colored cotton/angora blended yarns and on the back (next to skin) side pure natural col-ored cotton yarns are used in order to prevent skin from uncomfortable feeling. For comparison, a control sample is knitted using 100% natural colored cotton yarns in both sides. Thermal comfort properties of fabrics are measured. The effects of Angora fiber ratios in the blend and using different sides of fabrics next to skin are investigated. The results indicate that using Angora blended yarns on the back side of the fabric gives warmer feeling and thermal insulation values increase however water vapor permeability decreases with the in-crement of Angora rabbit fiber ratio.
