Multi-component fibers comprising at least one polymer having a softening temperature up to 150°C, and another polymer having a melting point of at least 130°C. The fibers are non- fusing up to at least 110°C. The fibers are useful, for example, for flowback control in wellbores and reservoirs.

La présente invention concerne des fibres à multicomposants renfermant au moins un polymère présentant une température de ramollissement allant jusqu'à 150 °C, et un autre polymère présentant un point de fusion d'au moins 130 °C. Les fibres ne fondent pas jusqu'à au moins une température de 110 °C. Les fibres sont utiles, par exemple, pour contrôler le reflux dans des puits de forage et des réservoirs.
