The study underlying this report was concerned with taking samples of seedcotton from the field and tracking them through the stages of ginning, spinning, and fabric production. Data on various attributes of the cotton was collected at several stages. The study has been designed from the standpoint that cotton is ultimately valued at the consumer product level, so the best way to gauge the effects of a particular factor in cotton processing is to analyz.e its effect on realised quality, that is, quality seen at the fabric stage. Prediction is one of the most important parts of the results of this project. The vision is to have a historical record of various lint attributes and the resulting realised quality (particularly white speck neppiness) that will allow the prediction of the realised quality of current day lint at the gin loadout door. 1bis would have the effect of removing much of the uncertainty in a multi-million dollar production chain that might involve several changes of ownership as well as long distances and long periods to produce a finished product.
