Aqueous anti-soiling composition

A composition for treating fibrous substrates to render said substrates durably resistant to dry soil and durably repellent to water and oil, said composition being an aqueous emulsion comprising:

• (a) a fluorochemical treatment comprising one or more fluorochemical compounds and one or more fluorine-free extender compounds;
• and
• (b) one or more fluorochemical surfactants comprising one or two fluorochemical groups and one or two water-solubilizing polar groups present in the emulsion in an amount effective to render said fibrous substrate durably resistant to dry soil and durably repellent to water and oil.

A composition for treating fibrous substrates to render said substrates durably resistant to dry soil and durably repellent to water and oil, said composition being an aqueous emulsion comprising:

• (a) a fluorochemical treatment comprising one or more fluorochemical compounds selected from the group consisting of fluorochemical urethanes, ureas, non-aromatic esters, ethers, alcohols, epoxides, allophanates, amides, amines, acids, carbodiimides, guanidines, oxazolidinones, isocyanurates, and biurets;
• (b) one or more ionic fluorinated surfactants comprising one or two fluorochemical groups and one or two water-solubilizing polar groups present in the emulsion in an amount effective to render said fibrous substrate durably resistant to dry soil and durably repellent to water and oil.

The method according to claim 29 wherein said composition is sprayed onto dry carpet, textiles, leather or paper.

• and
• (b) one or more ionic fluorinated surfactants comprising one or two fluorochemical groups and one or two water-solubilizing polar groups present in the emulsion in an amount effective to render said fibrous substrate durably resistant to dry soil and durably repellent to water and oil.
