Analysis and Optimization of the Concluding Stage of Orientation of Polypropylene Fibre

An algorithm and system for mathematical modeling and optimization of the concluding stage of orientation of PP fibre are proposed. The adequacy of the mathematical model was confirmed in different drawing regimes. Mathematical modeling of the process was conducted, which revealed the basic (formal) characteristics of the process and demonstrated the possibility of an analytical solution of the problem of optimizing the orientation process. The optimum regimes are obtained in linear and discrete orientational drawing that ensure attaining the maximum level of orientation with respect to the selected index. The algorithm and modeling system can be used in developing optimum process schemes and regimes, creating control systems, and in training process personnel.[PUBLICATION ABSTRACT]
