The present disclosure provides fibers and filaments formed from polyamide polymers polymerized with dual termination of the amino and carboxyl end-groups, referred to herein as dual-terminated polyamides, or dual terminated PA. In one embodiment, the dual-terminated polyamide is considered "highly terminated" and is useful in producing stain resistant textiles such as carpet fibers, for example. La présente invention concerne des fibres et des filaments formés à partir de polymères de polyamide polymérisés avec une terminaison double des groupes terminaux amino et carboxyle, appelés dans la présente description polyamides à terminaison double, ou PA à terminaison double. Dans un mode de réalisation, le polyamide à terminaison double est considéré comme « à terminaison élevée » et est utile dans la production de textiles anti-tache, tels que des fibres de tapis, par exemple.
