Rinsing dyed or white fabrics in a chelator-containing rinse bath restores color and brightness. Rinse added compositions comprising chelators such as diethylenetriamine pentaacetate or ethylenediamine disuccinate are used to restore the appearance of colored and white fabrics whose drab appearance has been caused by interactions with metal ions, especially copper and nickel. Compositions comprising the chelators in combination with fabric care auxiliaries such as fabric softeners, cellulase enzymes and chlorine scavengers are provided.
En rinçant des textiles colorés ou blancs dans un bain de rinçage contenant des agents chélateurs, on redonne à ces tissus leurs couleurs et leur éclat. Des compositions ajoutées à ce bain de rinçage, comprenant des agents chélateurs tels que diéthylène triamine pentacétate ou éthylène diamine disuccinate, sont utilisées pour permettre aux tissus colorés et blancs de retrouver leur aspect, l'apparence terne de ces tissus ayant été causée par des interactions avec des ions métalliques, tels que cuivre et nickel. Des compositions comprenant ces agents chélateurs en combinaison avec des adjuvants de traitement de tissus, tels que des adoucissants, des enzymes cellulases et des accepteurs de chlore, sont également décrites.
