Stain resistant polyamide textile products |
(57) Nylon or wool carpets and other polyamide products can be rendered stain resistant
by impregnation with an acid-soluble addition polymer comprising sulphonic groups
and aromatic, cycloaliphatic or heterocyclic groups, for instance dicyclopentadiene
sulphonate, generally in combination with a hydrophilic monomer such as (meth) acrylic
acid or maleic acid.
