  • Treatment method, which promotes the removal of dirt, for the surfaces of textiles and non-textiles
    Patent number: 7074750
    Abstract: A process for the soil release treatment of surfaces of textile and nontextile materials, in which cationically modified hydrophilic nanoparticles based on crosslinked polymers of (a) 60 to 99.99% by weight of one or more carboxyl-containing ethylenically unsaturated monomers or salts thereof, (b) 0 to 40% by weight of one or more water-insoluble monoethylenically unsaturated monomers, (c) 0.

  • Use of polymers containing urethane and/or urea groups for the modification of surfaces
    Publication number: 20030114057
    Abstract: The present invention relates to particulate, linear, sheet-like, or three-dimensional structures which comprise, at least on their surface, a hydrophilicizing amount of at least one polymer which has urethane groups and/or urea groups, and also ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.
