The aim of this study was to investigate the physical properties of yarns made with different blend ratios of meta-aramid, para-aramid, flame-resistant (FR) viscose, and antistatic nylon fibers, as well as the tensile strengths and burning behaviors of fabrics made from these yarns. For this purpose, 10 different yarns of two different linear densities were produced using five different blend ratios, which are commonly used in the production of fire-resistant fabrics, and knitted fabrics were produced from these yarns, with the same knitting machine and the same production parameters. Physical properties of the yarns and tensile properties and burning characteristics of the knitted fabrics were measured according to commonly applied standards, and the results obtained were evaluated using the SPSS statistical program. The findings of this study are that the blend ratios of meta-aramid, para-aramid, FR viscose, and antistatic nylon fibers have statistically significant effects on the unevenness, humidity, and tenacity of the yarns, as well as on the tensile properties and burning characteristics of the fabrics. It was found that, with an increase of the aramid fiber ratio in the blend, the tensile values of the yarns and fabrics increased. The lowest moisture contents were recorded for 100% para-aramid yarns but the highest moisture contents were recorded for yarns whose blends contained FR viscose fibers. The yarns whose blends contained antistatic nylon fibers exhibited the greatest unevenness and the most thin and thick places and neps.
