Abstract: The effect of winder type (i.e. spindle driven winder and drum driven winder), winding time, package diameter and winding tension on the measured values of package densities and physical bulk of air-jet textured yarn has been discussed. Surface driven winders produce packages of higher densities and the measured values of physical bulk are lower. The effect of yarn tension during winding on the measured values of the physical bulk is higher in the case of spindle driven winders as compared to drum driven winders. Winding at lower tension results in the higher values of measured physical bulk. Changes in the package densities of both parent and textured yam packages with change in winding time and package diameter affect the measured values of physical bulk while winding either on equal time or on equal diameter basis. For the measurement of physical bulk, it is recommended to wind the parent and textured yam packages of larger diameter in the case of equal diameter winding. Longer winding time is recommended to build the parent and textured yarn packages for the measurement of physical bulk in case equal winding time is used as the basis for building packages.
