41—AN APPLICATION OF MINI-COMPUTERS TO THE OPTIMIZATION OF THE OPEN-END-SPINNING PROCESS. PART II: CONSIDERATION OF THE CASE OF THREE VARIABLES

Abstract

The application of a mini-computer to the analysis of three-variable experimental designs (speed of opening cylinder, rotor speed, and twist multiplier) is studied with reference to the spinning of polyester-fibre-cotton blends. A technological interpretation of the results obtained is given, which generally confirms earlier work and also contributes new details of the phenomena determining the observed behaviour.
