Abstract
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.

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 and 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 water- and oil-repellent agent or the treatment liquid comprises a thermally gelling substance, or, in the step (3), the thermally gelling substance is used in addition to the treatment liquid and the thermally gelling substance is applied to the textile with contacting the thermally gelling substance with the treatment liquid.
A treatment liquid usable in a method of treating a 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 and 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.
A water- and oil-repellent composition comprising:
- (i) at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer and a fluorine-containing low-molecular weight compound, and
- (ii) a thermally gelling substance.
