To provide an antifouling processing agent composition capable of imparting oil repellency and antifouling properties (stain release properties), while suppressing a reduction in the water absorbency of a textile product. This antifouling processing agent composition comprises: a fluorinated polymer comprising from 30 to 70 mass % of units based on F(CF.sub.2).sub.nY—OCOCR═CH.sub.2 (wherein Y is an alkylene group, and R is a hydrogen atom, an alkyl group, or a halogen atom) and from 20 to 60 mass % of units based on CH.sub.2═CR.sup.1—COO—(R.sup.2O).sub.q—R.sup.3 (wherein R.sup.1 is a hydrogen atom or a methyl group, R.sup.2 is an alkylene group, and R.sup.3 is a hydrogen atom, an alkyl group, a (meth)acryloyl group, or a glycidyl group), and having a number average molecular weight of 3,000-500,000; and a fluorinated amphoteric surfactant having a C.sub.1-6 perfluoroalkyl group or a C.sub.3-9 perfluoroalkenyl group, and having a number average molecular weight of less than 3,000.

A textile having high fluorine adhesion rate, and excellent water- and oil-repellency can be obtained by a method of producing a treated textile, comprising steps of: (1) preparing a treatment liquid comprising a water- and oil-repellent agent which comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer or a fluorine-containing low molecular weight compound, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the treatment liquid comprises a thermally gelling substance.

Disclosed are spray-on anti-soil formulations, and methods for treating fibers, carpets, and fabrics with the same. The anti-soil formulations comprise a synergistic blend of an anti-soil component and a stain blocker component adapted to be sprayed-on a fiber, carpet, or fabric instead of known exhaust applications. The anti-soil component can be either fluorochemical or non-fluorochemical based, while the stain blocker can comprise any chemical that blocks positively charged dye sites. Fibers, carpets and fabrics treated with the anti-soil formulations exhibit superior anti-soil characteristics compared to sprayed-on fluorochemicals and exhibit similar anti-soil characteristics compared to known exhaust applications.
