Claims
- 1. A method of imparting stain and water resistance to a textile fabric, said method comprising:
- immersing said textile fabric in a pressurized liquid containing carbon dioxide and a surface treatment component; then
- depositing said surface treatment component on said textile fabric; and then
- separating said carbon dioxide from said textile fabric so that said surface treatment component remains deposited on said textile fabric;
- wherein said surface treatment component comprises a CO.sub.2 -philic segment, and wherein said CO.sub.2 -philic segment is selected from the group consisting of fluorine-containing segments, siloxane-containing segments, and mixtures thereof.
- 2. A method according to claim 1, wherein said depositing step is carried out by lowering the pressure of said liquid.
- 3. A method according to claim 1, wherein said depositing step is carried out by diluting said liquid.
- 4. A method according to claim 1, wherein said depositing step is carried out by raising the temperature of said liquid.
- 5. A method according to claim 1, wherein said liquid is a non-aqueous liquid.
- 6. The method according to claim 1, wherein said surface treatment component imparts stain release properties to said fabric.
- 7. The method according to claim 1, wherein said fabric comprises a carpet.
- 8. The method according to claim 1, wherein said fabric comprises a garment.
- 9. The method according to claim 8, wherein said garment is formed of silk or acetate.
- 10. The method according to claim 8, wherein said garment is selected from the group consisting of ties, dresses, blouses and shirts.
- 11. The method according to claim 1, wherein said CO.sub.2 -philic segment is a fluorine-containing segment.
- 12. The method according to claim 1, wherein said fluorine-containing segment is a fluoropolymer.
- 13. The method according to claim 1, wherein said CO.sub.2 -philic segment is a siloxane-containing segment.
- 14. A method according to claim 1, wherein said fabric comprises upholstery.
- 15. A method of imparting stain and water resistance to a textile fabric, said method comprising:
- immersing said textile fabric in a pressurized liquid containing carbon dioxide and a surface treatment component; then
- depositing said surface treatment component on said textile fabric; and then
- separating said carbon dioxide from said textile fabric so that said surface treatment component remains deposited on said textile fabric;
- wherein said surface treatment component comprises a CO.sub.2 -philic segment, and wherein said CO.sub.2 -philic segment is selected from the group consisting of fluorine-containing segments, siloxane-containing segments, and mixtures thereof;
- and wherein said fabric comprises wool or cotton.
- 16. A method according to claim 15, wherein said depositing step is carried out by lowering the pressure of said liquid.
- 17. A method according to claim 15, wherein said depositing step is carried out by diluting said liquid.
- 18. A method according to claim 15 wherein said depositing step is carried out by raising the temperature of said liquid.
- 19. A method according to claim 15, wherein said liquid is a non-aqueous liquid.
- 20. The method according to claim 15, wherein said surface treatment component imparts stain release properties to said fabric.
- 21. The method according to claim 15, wherein said fabric comprises a garment.
- 22. The method according to claim 15, wherein said CO.sub.2 -philic segment is a fluorine-containing segment.
- 23. The method according to claim 15, wherein said fluorine-containing segment is a fluoropolymer.
- 24. The method according to claim 15, wherein said CO.sub.2 -philic segment is a siloxane-containing segment.
