Abstract

The invention relates to a stain release and repellant fabric conditioner comprising a repel type fluorochemical and/or siloxane, a release type fluorochemical and/or siloxane, and a performance extender.

Claims

1. A stain release and repellant fabric conditioner comprising a repel type fluorochemical, a release type fluorochemical, and a performance extender.

2. The stain release and repellant fabric conditioner of claim 1, wherein the repel type fluorochemical is selected from the group consisting of fluorinated acrylates, fluorinated urethanes, and fluorinated dendrimers.

3. The stain release and repellant fabric conditioner of claim 1, wherein the release type fluorochemical is a hybrid dual function fluoropolymer or C4 type fluoropolymer.

4. The stain release and repellant fabric conditioner of claim 1, wherein the performance extender is a quaternary ammonium compound.

5. The stain release and repellant fabric conditioner of claim 1, wherein the repel type fluorochemical and the release type fluorochemical have melting temperatures of between 25 and 100 degrees Celsius.

6. The process of applying soil release fabric conditioner comprising:

washing fabric with a detergent and water;

adding the stain release and repellant fabric conditioner of claim 1 to a rinse cycle; and

,

removing the water from the fabric.

7. The process of claim 6, wherein the fabric conditioner is added in an amount such that the release type and repel type fluorochemicals are greater than 0.03% by weight of the fabric.

8. The process of claim 6, wherein the fabric conditioner is added in an amount such that the release type and repel type fluorochemicals are between 0.06 and 2.0% by weight of the fabric.

9. The process of claim 6, wherein the fabric conditioner is added in an amount such that the release type and repel type fluorochemicals are between 0.35 and 0.65% by weight of the fabric.

10. The process of claim 6, wherein the rinse cycle has a temperature of at least 15 degree Celsius.

19. A fabric treated with the stain release and repellant fabric conditioner of claim 1.

11. A stain release and repellant fabric conditioner comprising a propoxylated hydroxyl- or amino-polysiloxane and a performance extender.

12. The stain release and repellant fabric conditioner of claim 11, wherein the performance extender is a quaternary ammonium compound.

13. The stain release and repellant fabric conditioner of claim 11, wherein the propoxylated hydroxyl- or amino-polysiloxane comprises an amino siloxane reacted with a fatty chain and a performance extender.

14. The stain release and repellant fabric conditioner of claim 13, wherein the fatty chain is selected from the group consisting of lauryol, stearoyl, or tallowoyl.

15. The process of applying soil release fabric conditioner comprising:

washing fabric with a detergent and water;

adding the stain release and repellant fabric conditioner of claim 11 to a rinse cycle; and

,

removing the water from the fabric.

16. The process of claim 15, wherein the fabric conditioner is added in an amount such that the polysiloxane is between 6 and 8% by weight of the extender.

20. A fabric treated with the stain release and repellant fabric conditioner of claim 11.

17. A stain release and repellant fabric conditioner comprising a repel type fluorochemical and a performance extender.

18. A stain release and repellant fabric conditioner comprising a release type fluorochemical and a performance extender.
