Abstract
A mathematical model for the process of forming of synthetic fibers moving as a bundle is formulated. Three main versions are considered: forming of exposed bundles, forming in shafts with blowing, and stretching of fibers by means of an ejector. Low and high-speed forming regimes are also considered within the framework of the Maxwell model of a viscoelastic fluid. The calculations performed showed that the parameters of the fiber bundle produced depend on the method of forming used and on the local conditions in high-speed stretching, accompanied by oriented crystallization.
