Patent

CA 2522643

Textiles are cleaned by first treating soiled areas of the textile with at least one pre-spotter material which is an alcohol polyoxyalkylene derivative or a benzoate ester. The textiles are subsequently dry cleaned in a medium based on liquid C02, typically also including a cleaning additive, particularly a multi-ester. The textile may also be treated with a fabric conditioner, particularly a fatty alcohol or fatty acid branched polyalkoxylate which may be included in the dry cleaning medium or in a subsequent rinse cycle.

Selon l'invention, des textiles sont nettoyés tout d'abord par traitement de zones sales du textile à l'aide d'au moins une matière de pré-détachage à la main qui est un dérivé d'alcool polyoxyalkylène ou un ester de benzoate. Les textiles sont ultérieurement nettoyés à sec dans un milieu à base de CO¿2? liquide, comprenant généralement aussi un additif de nettoyage, notamment un multi-ester. Le textile peut également être traité à l'aide d'un conditionneur de tissus, notamment un polyalcoxylate ramifié d'alcool gras ou d'acide gras qui peut être introduit dans le milieu de nettoyage ou au cours d'un cycle de rinçage ultérieur.
