A carrier liquid for agent concentrates which are added to polymerizates that are suitable for melt spinning is proposed, the carrier liquid comprising three components, namely a) a base oil as main constituent having a thermostability of more than 300~C; b) at least one antioxidant acting as a radical trap; and c) at least one compound which deactivates catalysts for the polymerization of fiber-forming materials that are suitable for melt spinning. The carrier liquid is used for the production of an agent concentrate which contains color pigments, bactericides and/or fungicides for polymerizates that are suitable for melt spinning. The agent concentrates are used for spin dyeing textile fibers and technical fibers, particularly partially oriented yarns.
L~invention porte sur un liquide porteur pour concentré d~agent que l~on ajoute à des produits polymérisés convenant à la fusion centrifuge, le liquide porteur comprenant trois composants, à savoir a) une huile de base comme composant principal ayant une thermostabilité supérieure à 300°C; b) au moins un antioxydant faisant office de piège de radicaux ; et c) au moins un composé qui désactive les catalyseurs pour la polymérisation des matériaux de formation de fibres convenant à la fusion centrifuge. Le liquide porteur sert à la fabrication d~un concentré d~agent qui contient des pigments de couleur, des bactéricides et/ou des fongicides pour produits polymérisés convenant à la fusion centrifuge. Les concentrés d~agent servent à la teinture centrifuge de fibres textiles et fibres techniques, en particulier les fils partiellement orientés.
