Conclusions
-- The effect of the component air streams on yarn uniformity with respect to linear density has been established. This has afforded opportunity to find an optimum regime for yarn cooling in spinning from polymer melts. Analysis of the pulsations in air streams has made it possible to determine the basic sources for their origin and ways to reduce them.
-- A manufacturing control of the yarn cooling regime using anemometers has been proposed.
-- A way of intensifying the yarn cooling regime using an air jet on the yarn section after its initial hardening has been described.
-- It is recommended to use the method of investigating the process of yarn spinning by analysis of the component air streams in preparing fibres from polymer melts on any type of spinning equipment.
