Abstract

L'utilisation d'agents de traitement de tissus et de substrats tensio-actifs spéciaux permet d'obtenir des propriétés détachantes améliorées tout en réduisant les résidus. Ces agents sont particulièrement appropriés pour l'utilisation dans des dispositifs de traitement de tissus dans lesquels un ou plusieurs produits textiles sont traités ou régénérés dans un conteneur (par exemple, un sac), avec chauffage et nutation, dans un sèche-linge à rotation. L'invention concerne en outre un procédé de nettoyage à sec, ainsi qu'un dispositif de nettoyage à sec renfermant l'agent de traitement de tissus et, le cas échéant, le substrat tensio-actif.
