This evaluation of a state-of-the-art ring spinning machine versus a ring spinning machine with 40-year-old technology reveals highly significant and beneficial effects of the new technology on yarn quality. Furthermore, there are notable cotton-machinery interactions, meaning that different cottons may perform differently as the new spinning technology is adopted. Simple regression analyses clearly show that the impacts of the fiber quality parameters are different on the two machines. The new spinning technology produces consistently superior yarns from the same fiber properties. Furthermore, the new technology is much less sensitive to some fiber quality problems, such as short fiber content and neps. Over the range of values examined here for short fiber content and neps, there were no significant changes in yarn quality values with the new technology. These results serve to remind us that it is not always true that the faster speeds of textile machinery require higher quality in textile fibers. This report illustrates a case where the newer, faster technology actually compensates for some of the quality problems in the raw material.
