This paper is focused on investigating the abrasion and tensile properties of fabrics from conventional and fire resistant type polyester yarns. In the experimental study, twelve different types of fabrics composed of four different weft yarns with three levels of weft density were selected in order to determine the influence of weft density and yarn structural parameters (texturing and addition of flame retardant material) on tenacity and abrasion resistance. The weft yarns were conventional textured polyester yarn (CTP), air-jet textured polyester yarn (ATP), conventional textured flame retardant polyester yarn (CTPFR), air-jet textured flame retardant polyester yarn (ATPFR). Trilobal bright flat polyester was used as the warp yarn for all the fabrics. After the satin type drapery fabrics were woven, the abrasion tests of the fabrics were performed with Martindale test equipment while the tenacity tests were carried out by using Instron test device. According to the results of the statistical analyses performed using the experimental values obtained from the tests, we determined that, the abrasion resistance and the tensile properties in warp and weft directions were affected by the yarn structural parameters (such as texturing and the addition of flame retardant material) and weft density.
