34—AN APPLICATION OF MINI-COMPUTERS TO THE OPTIMIZATION OF THE OPEN-END-SPINNING PROCESS. PART I: CONSIDERATION OF THE CASE OF TWO VARIABLES

Abstract

The application of the technique of the central compound rotatable designs of Box and Hunter to the optimization of an open-end-spinning process is studied, and the advantages of using a minicomputer for such an analysis are discussed. The influence of the rotor diameter, rotor speed, and yarn twist on the characteristics of open-end-spun cotton yarns is studied. In each case, the optimum conditions within the industrially acceptable limits of the process are established.
