Abstract

Polyester waste is worked up by (a) comminuting the waste, (b) converting the comminuted material into granules by means of heat and pressure using oppositely working comminuting elements, and (c) spinning the granules into fibres. Enables fibres suitable for prodn. of textiles to be obtained cheaply from polyester waste, opt. together with polyamide waste.
