Investigation of the effect of elastane poliesteryarn production parameters on yarn and fabric properties

In this study, the effects of elastane-containing polyester yarn production parameters on yarns and woven fabric properties obtained from these yarns were investigated. For this purpose, 36 different types of woven fabrics were produced by changing the filament count, elastane yarn count, elastane draw ratio and the nozzle type used in the centering process, 36 different polyester yarns with elastane content and 36 different woven fabrics using twill 3/3 weave from these yarns under constant production conditions. In order to investigate the effect of production parameters on yarn properties, yarn linear density, number of centers, center persistence, yarn breaking strength and breaking elongation values; In order to examine the effects of production parameters on fabric properties, fabric strength, elongation and comfort properties were tested in accordance with the standards. The values obtained after the tests were evaluated in the SPSS statistical program. As a result of the study, it was seen that the effect of polyester yarn filament number, elastane number, elastane draw ratio and the nozzle type used in the centering process on the yarn strength, number of centers, and center persistence values were statistically significant. Fabric tensile strength and elongation values increased with increasing filament number and elastane number. When the comfort properties were examined, it was concluded that as the filament number and elastane number increased, water vapor permeability and thermal conductivity increased, and air permeability decreased.
