In this study, we present a novel approach to simulate and characterize the behavior of fibers during processing using a modified version of the familiar rotor ring system. With this modification, we attempt to create an area approximately resembling the carding zone and measure the energy required to shear the fibers in this area. We then use the energy readings to provide an index of fiber processing propensity. Such an index is believed to be a function of combined fiber cohesion and fiber resiliency. In addition to the rotor ring, we present corresponding results from other independent techniques such as NIR wax analysis and sliver cohesion. The most important finding of this part of the study is that deterioration in the quality of yarns and fabrics should not be rationalized only on the basis of standard fiber properties (such as length, fine ness, and strength) and that measures of processing propensity, wax content, and sur face cohesion provide a complete picture of fiber processibility and its impact on end product quality.
