DETAILED DESCRIPTION OF THE INVENTION                     Fabric treatment method and composition therefor                               Technical field   The present invention relates to a method for treating fabrics and a liquid detergent composition for use in said method. I do. The compositions of the present invention include a bleaching system.                               Background art   An object of the present invention is to provide an aqueous medium having a bleaching system and optionally a metal catalyst. And a method for treating cloths, which is characterized by contacting with a fabric. Bleach And metal catalysts in combination serve as bleaching or dye transfer control systems One. Yet another object of the present invention is to provide a composition suitable for use in the above method. It is in.   Cleaning with improved anionic species, such as anionic surfactants and builders Fabrics may cause certain anionic species such as anionic surfactants, builders, etc. It is highly desirable to contact with an aqueous medium containing Anionic species present in the medium Need to be neutralized by a neutralization system. Often anionic species, especially anions The ionic surfactant has been incorporated into the neutralized detergent composition. Other shades Species, such as builders, are aqueous in contact with the fabric in this composition or more rarely It may be neutralized in the medium itself. For example, anionic surfactants are neutralized during washing Cleaning performance of this composition is impaired if And the whiteness performance of the composition will be adversely affected. Thus, the neutralization system Is a very important component in the medium. Normally used for technical anion species Sodium hydroxide and alkanolamines, in particular, especially Noethanolamine. However, when considering the choice of neutralization system In addition, the compatibility of the other components in the cleaning solution must be considered.   One such component improves the cleaning and whiteness performance of the cleaning process Bleaching agent required for In addition, the bleaching system is used for bleaching of fabric (fabric) and Required for bleaching of stains on fabric. In particular, the presence of bleaches can provide a bleaching system. It may be used in combination with a metal catalyst.   Unfortunately, the inventors have found that bleaching agents may be alkanols such as monoethanolamine.

Thus, the problem starts, for example, the cleaning method Until the bleach and monoethanolamine have been separated, Occurs in solids and in aqueous media of washing liquids. Therefore, monoethano Luamine was not found to be a suitable neutralizing system.   Bleach in combination with metal catalysts in addition to providing benefits on whiteness bleaching Prevents the transfer of dye from one cloth to another during washing, thereby Provides the benefit of improving chromaticity maintenance. Therefore, these components are Is highly desirable. Such DTI systems are, for example, co-pending European State Patent Applications Nos. 92870181, 92870184.6 and And No. 92870183.8. However, the DTI system There are a number of issues associated with the existence of In an aqueous medium, the metal catalyst It is this activated species that is activated by the bleach and inhibits dye transfer. . We have found that this species is not compatible with other components in the aqueous medium, especially the neutralizing system for anionic species. I have now found that I am always sensitive. For example, monoethanolamine and All other alkanolamines immediately deactivate the activated metal catalyst and therefore It is not suitable for the present invention.   In response to these purposes, the expression (Where R₁~ R_FourIs independently C₁~ C₆Alkyl, phenyl, hydroxyalkyl Or an alkoxyalkyl group) For neutralization of anionic species containing quaternary ammonium cations represented by The system is now found to be compatible with peroxygen bleaches and possibly metal catalysts.
