In this study, the effects of elastane weft yarn count and knitting type on the physical and comfort properties of elastane weft double-layer woven fabrics for outerwear investigated experimentally. For this purpose, warp yarn and warp density are kept constant. Three different weaving structures with 2, 3, and 8 connections were used. Nine different double-layer woven fabrics were produced using intermingled yarn with three different elastane counts (20,40,70). Three plain fabrics are woven with the same yarns to compare the double layer fabric properties with single-layer fabrics. Sample fabrics were finished under the same conditions. Weight, density, and thickness properties of the dry relaxed raw fabrics were determined. Weft density, warp density, weight, thickness, air permeability, moisture conduction, water vapor permeability, heat conduction, tensile strength, percent elongation, pilling, and abrasion resistance properties of the dry relaxed finished fabrics were determined. The results were evaluated statistically in SPSS 22 package program. When the results are analyzed, it was seen that the increase in the count of elastane and the number of connections has the same effect on the double-woven fabrics. It has been determined that as the elastane used in weft yarn in double layer fabric samples thicken, the weight, thickness, water vapor permeability resistance, thermal conductivity, and thermal resistance values of the fabric will increase. There was a decrease in elongation percentage, air, and water vapor permeability values. As the number of connections used in double-layer fabrics increased, the fabric's weight and water vapor permeability increased.
