We studied the structural properties, bursting strength and pilling properties of single jersey knitted fabrics made from OE rotor spun yarns. Raw material of 100% cotton of the Urfa region of Turkey was specifically handled in the study. The yarns were produced with different nozzle types with a yarn of linear density of 19.67 tex. Five different ceramic nozzles were used in yarn production. These nozzle types are known as K4KK, K4KS, K6KF, K8KK & KSNX. Fabrics were produced by a 28 gauge 32 inch diameter circular knitting machine. The yarns were processed to single jersey knitted fabrics by adjusting the yarn loop length between 14 - 17 cm on the machine as they were the minimum and maximum values limited by the yarn type, machine and commercially accepted conditions. The purpose of this paper was to investigate the effect of fabric density and nozzle type on the structural and performance properties of single jersey knitted fabrics investigated in both a grey and dyed state. In addition, results were interpreted statistically and regression equations obtained.
