Polyamide-containing fibre materials can be given an anti-stain finish by treating them with a sulpho-containing aromatic formaldehyde condensation product in combination with polyacrylic acid, the treatment with the two components being carried out in any desired order or simultaneously.

Anti-stain finishing of polyamide-containing fibre materials,

The aromatic formaldehyde condensation products, which are substantially colorless and water-soluble and contain sulphonate and/or carboxylate groups, are obtainable by adding agents which have a reducing action during and/or after the condensation reaction, and are suitable for the treatment of textiles and leather.
