Abstract

Method for treating a hydrophobically-modified textile with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme, rinsing and drying the textile. Use of the finishing step for improved cleaning with an aqueous solution of a nuclease enzyme, preferably a deoxyribonuclease or ribonuclease enzyme.

First claim

What is claimed is:

1. A method of treating a textile comprising the steps of:
(i) providing a hydrophobically-modified textile;
(ii) contacting the textile from step (i) with an aqueous solution consisting of a nuclease enzyme.

2. A method according to claim 1 , wherein the nuclease enzyme is present at a concentration of from about 0.01 ppm to about 1000 ppm.

3. A method according to claim 1 wherein the nuclease is selected from any of E.C. classes E.C. 3.1.21.x (where x=1, 2, 3, 4, 5, 6, 7, 8, 9), 3.1.22.y (where y=1, 2, 4, 5), E.C. 3.1.30.z (where z=1, 2) or E.C. 3.1.31.1, or mixtures thereof.

4. A method according to claim 3 wherein the nuclease is selected from E.C. class E.C. 3.1.21.1.

5. A method according to claim 1 wherein the nuclease enzyme comprises a deoxyribonuclease.

6. A method according to claim 2 in which the enzyme comprises an enzyme having both RNase and DNase activity.

7. A method according to claim 6 in which the enzyme is from E.C. 3 . 1.30.2.

8. A method according to claim 1 wherein the enzyme is a microbial enzyme.

9. A method according to claim 8 wherein the enzyme is a bacterial enzyme.

10. A method according to claim 1 wherein the enzyme has an amino acid sequence having at least about 85% identity with the amino acid sequence shown in SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3.

11. A method according to claim 1 wherein the textile comprises a blended textile comprising polyester.

12. A method according to claim 1 wherein following step (ii) there is a rinsing and drying step.

13. A method according to claim 1 wherein the hydrophobic modification of the textile is in the form of a finishing step provided in textile manufacturing.

14. A method according to claim 1 wherein the hydrophobic modification of the textile is in the form of a finishing step provided in the textile manufacturing comprising applying a cationic compound, silicone, paraffin or fluorinated compound to the textile.
