Abstract (en)

[origin: FR2780987A1] The invention concerns a method for making polyamide fibres with suitable and compatible characteristics for use as fibres for making felt for paper machines. More particularly the invention concerns a method which consists in adding stabilising additives in the polyamide to obtain polyamide fibres with high characteristics, in particular high resistance to light, heat and aggressive environment. The method consists in adding the stabilising agent directly into the polyamide without forming a preparatory mixture, then in producing a mixture of the polyamide and the additive in an extruder feeding the composition into a die to obtain filaments.
