Abstract: A method of converting a plastics material into a yarn, in which the plastics material includes one or more polymers selected from the group consisting of nylon, polyesters, polyethylene, polyvinyl chloride, polyphenylene sulphide, polystyrene. The method includes heating the material to melt it, pumping the melted material through an extruder to form an extruded filament, and cooling the extruded filament. The cooled filament is passed through a first draw roller assembly while elevating the temperature of the filament. The filament is then heated in a heating zone as it exits the first draw roller assembly and, thereafter, the filament is passed through a second draw roller assembly operating at a different linear speed to the first draw roller assembly. The filament is spooled after exiting the second draw roller assembly.

Abstract: A method of converting a plastics material into a yarn includes heating the material to melt it and pumping the melted material through an extrusion die (114) to form an extruded filament (116). The extruded filament is cooled and passed through a first draw roller assembly (122) while elevating the temperature of the filament. The filament (116) is heated in a heating zone (126) as it exits the first draw roller assembly. Thereafter the filament is passed through a second draw roller assembly (134) operating at a different linear speed to the first draw roller assembly (122). The filament (116) is spooled after exiting the second draw roller assembly (134).
