Claims24
A water- and oil-repellent treating agent for fibrous substrates comprising a fluorochemical type water- and oil-repellent agent, a carbodiimide compound, and at least one component selected from the group consisting of plasticizer, an aluminum zirconium, or titanium metal ester or alcoholate, aziridine, zirconium salt, alkylketen dimer, alkenyl succinic anhydride.
Method of treating fibrous substrates comprising:
- A) contacting said fibrous substrate with a solution comprising a fluorochemical type water- and oil-repellent agent, carbodiimide compound and at least one component selected from the group consisting of plasticizer, or aluminum, zirconium, or titanium metal ester or alcoholate, aziridine, zirconium salt, alkylketen dimer, alkenyl succinic anhydride;
- B) drying the substrate resulting from Step A.
