Abstract

Selon l'invention, on utilise cette composition d'entretien de tissus qui comprend, d'une part, un initiateur de radicaux, lequel est préférablement un photoamorceur et est choisi dans le groupe constitué par des photoamorceurs d'abstraction d'un hydrogène, des photoamorceurs de radicaux de clivage, ou des mélanges de ces photoamorceurs, et d'autre part, un terminateur de radicaux, pour traiter un tissu, par exemple dans un système d'enlèvement de taches, lors du lavage ou du rinçage du tissu, dans un processus de lavage. On peut incorporer ce système de traitement de tissus dans une composition de lavage de tissus, ou dans une composition adoucissante.
