Manufacturing performance and product quality depends on the fiber quality characteristics in a mix laydown. Most researchers agree that there is a best combination of fiber properties for each manufacturing system and product produced. Thus we must determine the optimum fiber properties, averages and standard deviations, to place in a mix laydown for each manufacturing system and end product. After this has been determined, the task becomes one of selecting mix laydowns so that they are consistent -- day after day.

An overview is given of the present bale selection systems and their capability to characterize fiber properties of a mix laydown. Typical reasons for lack of control of fiber properties in mix laydowns are discussed. Also, bale management systems that may improve consistency in mixes are presented. It is of utmost importance that the system used contribute to continual improvements in manufacturing performance and product quality.
