Abstract

Manufacture of high strength polyamide (nylon 66) or polyester yarns by the after-polymerisation of chips of polymer of normal relative viscosity (40-50) to give a polymer of relative viscosity of 80 or more, in which the polymer chips are allowed to fall through an ascending current of hot dry nitrogen directly into a screw extruder, in which they are melted and from which the melt passes via a metering pump to a spinneret to be melt spun in the normal way. Very high tenacity yarns can be produced with constant mechanical properties suitable for use as tyre cord or as reinforcement for high pressure tubing or the like.
