    • 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) 0.01 to 30% by weight of one or more polyethylenically unsaturated monomers, (d) 0 to 25% by weight of one or more sulfonic acid- and/or phosphonic acid-containing monomers or salts thereof, (e) 0 to 30% by weight of one or more water-soluble nonionic monomers are applied to the surface of the materials from an aqueous dispersion, where the dispersion of the hydrophilic nanoparticles can be stabilized with anionic, nonionic and/or betainic emulsifiers and/or protective colloids, and where the hydrophilic nanoparticles have a particle size of from 10 nm to 2 μm and have been cationically modified by coating their surface with one or more cationic polymers, one or more polyvalent metal ions and/or one or more cationic surfactants.
    • 一种纺织和非纺织材料表面的污垢释放处理方法,其中基于(a)60-99.99重量%的一种或多种含羧基的烯属不饱和单体或其盐的交联聚合物的阳离子改性亲水性纳米颗粒( b)0至40重量%的一种或多种水不溶性单烯属不饱和单体,(c)0.01至30重量%的一种或多种多烯属不饱和单体,(d)0至25重量%的一种或多种磺酸 含酸和/或膦酸的单体或其盐,(e)0至30重量%的一种或多种水溶性非离子单体,由水分散体施加到材料的表面上,其中, 亲水性纳米颗粒可以用阴离子,非离子和/或甜菜碱乳化剂和/或保护胶体稳定,并且其中亲水性纳米颗粒具有10nm至2μm的粒度并且已被阳离子改性 用一种或多种阳离子聚合物,一种或多种多价金属离子和/或一种或多种阳离子表面活性剂涂覆它们的表面。
