Abstract (en)
[origin: EP0779382A1] A process is claimed for the production of hydrolysis-resistant polyester (PES) fibres and filaments, in which a masterbatch containing a polymeric vehicle (I) and an end group-blocker (II) together with the fibre-forming PES material is fed into the spinning nozzle. Component (I) contains practically no end groups which are able to react with (II) under the production conditions. Also claimed is (i) a masterbatch as above, and (ii) PES fibres or filaments with enhanced resistance to hydrolysis, containing end group blockers as above.
