In this study, influence of draw ratio, hot-pin temperature, and overfeeding on the color values of air-jet textured yarns, which were produced from polyester partially oriented yarn, was investigated. Two different air-jet textured yarns were produced by setting the value of only one variable to its minimum and maximum, while the reference values selected for the production of the reference yarn were used for the rest of the variables. Six different air-jet textured yarns, which were produced by varying draw ratio, hot-pin temperature, and overfeeding, and the reference air-jet textured yarn were dyed with the same dyeing procedure. Some physical properties such as linear density, tenacity, and breaking extension of the air-jet textured yarns were measured and images of the cross-section of the yarns were taken. The color coordinates of the dyed yarn samples were also measured. The color differences of six yarn samples compared to reference air-jet textured yarn were calculated. Changing draw ratio, hot-pin temperature, and overfeeding affected the color values of the air-jet textured yarns according to the results. It was found that, overfeeding is the parameter that affects the color values of the air-jet textured yarn most.
