To obtain a stain-proofing agent for carpet having excellent resistance to cleaning by formulating a specific fluorine-containing, stain-proofing agent and a triazine ring-containing crosslinking agent thereto.
The objective stain-proofing treatment agent for carpets is prepared by using a fluorine-containing stain-proofing agent including a fluoroalkyl groups-containing compound and a triazine ring-containing compound, for example, trimethylolmelamine or hexamethylolmelamine. The carpet is treated with the stain-proofing agent in an amount of 50-10,000 ppm calculated as fluorine atom whereby the objective stain-proof carpet with the stain-proof percentage of ≥30% is obtained, when the percentage is defined as follows: the stain-proof percentage in % = 100×(ΔEN-ΔETN)/ΔEN (ΔEN and ΔETN are each the color difference in the stain-proof tests on the untreated carpet and the treated carpet).
