The invention provides a stainblocking agent for a polyamide textile material. The stainblocking agent comprises a normally water-soluble resin, which is the free sulphonic acid form of a condensation of sulphonated 4,4'-dihydroxydiphenyl sulphone and formaldehyde, and an effective amount of sodium lauryl sulphate to enhance the light-fasteness of the stainblocking agent. The invention also provides a method for imparting stain resistance to a polyamide textile material which comprises treating the material by applying an effective amount of the stainblocking agent agent to impart stain resistance to the material. |
