Title:
TREATMENT METHOD, WHICH PROMOTES THE REMOVAL OF DIRT, FOR THE SURFACES OF TEXTILES AND NON-TEXTILES
Document Type and Number:
WIPO Patent Application WO2002103105
Kind Code:
A3
Abstract:
The invention relates to a treatment method, which promotes the removal of dirt, for the surfaces of textiles and non-textiles. According to said method, cationically modified, hydrophilic nanoparticles, based on cross-linked polymers, are applied from an aqueous dispersion to the surface of the materials. Said cross-linked polymers consist of (a) between 60 and 99.99 wt. % of one or more ethylenically unsaturated monomers containing carboxyl groups, or the salts thereof, (b) between 0 and 40 wt. % of one or more water-insoluble, monoethylenically unsaturated monomers, (c) between 0.01 and 30 wt. % of one or more ethylenically polyunsaturated monomers, (d) between 0 and 25 wt. % of one or more monomers containing sulphonic acid and/or phosphonic acid, or the salts thereof, (e) between 0 and 30 wt. % of one or more water-soluble, non-ionic monomers. The dispersion of the hydrophilic nanoparticles can be stabilised with anionic, non-anionic and/or betainic emulsifiers and/or protective colloids. The hydrophilic nanoparticles have a particle size of between 10 and 2 mu m and are modified cationically by covering their surface with one or more cationic polymers, one or more polyvalent metallic ions and/or one or more cationic surfactants.
