Abstract

A method for reducing force needed for ironing a fabric comprising laundering the fabric with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with —N—(—CH 2 —CH(OH)—CH 2 —Cl) 2 , wherein the linear polyether is deposited on the fabric and reduces the force needed for ironing.

First claim

What is claimed is:

1. A method for reducing force needed for ironing a fabric comprising laundering the fabric with a composition comprising:
a) a linear polyether having a weight average molecular weight less than 2000 that is terminated with —N—(—CH 2 —CH(OH)—CH 2 —Cl) 2 ,
b) a chelating compound comprising a mixture of an amino carboxylic acid compound and an organo aminophosphonic acid compound,
c) a cationic softener comprising difatty diamide ammonium methyl sulfate, and
d) lactic acid,

wherein the linear polyether is deposited on the fabric and reduces the force needed for ironing, and wherein the polyether is present in the composition in an amount of 0.05 to 0.8% by weight of the composition,
wherein the aminocarboxylic acid compound comprises nitrilotriacetic acid (NTA).

2. The method of claim 1 , wherein the fabric is wrinkled.

3. The method of claim 1 , wherein the fabric is laundered at least 3 times.

4. The method of claim 1 , wherein the composition is an aqueous composition.

5. The method of claim 1 , wherein the composition is added during a rinse cycle during laundering.

6. The method of claim 1 , wherein the laundering comprises washing the fabric and rinsing the fabric.

7. The method of claim 1 further comprising drying the fabric.

8. The method of claim 7 , wherein the drying is line drying.

9. The method of claim 7 , wherein the drying is dryer drying.

10. The method of claim 1 further comprising ironing the fabric.

11. The method of claim 1 , wherein the composition further comprises a surfactant.

12. The method of claim 1 , wherein the method reduces the force needed for ironing by at least 5% as compared to a force for ironing without laundering with the linear polyether.

13. The method of claim 1 , wherein the amino carboxylic acid compound further comprises one or more of ethylenediamine tetraacetic acid (EDTA); N-hydroxyethylenediamine triacetic acid; and diethylenetriamine pentaacetic acid (DEPTA).

14. A method for reducing force needed for ironing a fabric comprising laundering the fabric with a composition comprising:
a) a linear polyether having a weight average molecular weight less than 2000 that is terminated with —N—(—CH 2 —CH(OH)—CH 2 —Cl) 2 ,
b) nitrilotriacetic acid (NTA),
c) an esterquat, and
d) lactic acid,

wherein the linear polyether is deposited on the fabric and reduces the force needed for ironing, and wherein the polyether is present in the composition in an amount of 0.05 to 0.8% by weight of the composition.

15. The method of claim 1 , wherein the cationic softener further comprises an esterquat, an imidazolinium quat, ditallow dimethyl ammonium chloride, or mixtures thereof.

16. The method of claim 1 , further comprising a thickener.

17. The method of claim 16 , wherein the thickener comprises a water soluble cross-linked cationic polymer.

18. The method of claim 17 , wherein the water soluble cross-linked cationic polymer is derived from the polymerization of from 5 to 100 mole percent of cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent.

19. The method of claim 1 , wherein the organo aminophosphonic acid compound comprises ethylenediamine tetrakis(methylenephosphonic acid).

20. The method of claim 19 , wherein the organo aminophosphonic acid compound further comprises one or more of 1-hydroxyethane 1,1-diphosphonic acid (HEDP); and aminotri(methylenephosphonic acid).
