The disclosure generally relates to bicomponent fibers, and more particularly, methods to make bicomponent fibers and articles comprising them, wherein a first extruded component has a moisture level less than a second extruded component. The bicomponent fibers may comprise polyesters and are useful in articles such as carpets and fabrics. L'invention concerne de manière générale des fibres à deux composants, et plus particulièrement des procédés de fabrication de fibres à deux composants et des articles les comprenant, un premier composant extrudé ayant un niveau d'humidité inférieur à un second composant extrudé. Les fibres à deux composants peuvent comprendre des polyesters et sont utiles dans des articles tels que des tapis et des tissus.
