<p>Dirty textiles are treated in a washing bath that contains surfactants and if desired other usual components of washing baths under the influence of ultra-sound. The washing bath further contains insoluble pigment and/or fat stain captors which can be manually or mechanically separated from the textile after cleaning. The captors are polyquaternary ammonium compounds, preferably immobilised on the surface of insoluble carriers. In a multistage process, after pigments and fats have been removed, bleachable and/or enzymatically affected stains are removed with the help or bleaching or enzymatically active adjuvants.</p> |
