Abstract

A method for the artificial aging of fabrics by applying an enzyme compound without using an aqueous bath.

Claims

1. A method for artificially aging textile garments, especially cotton or denim garments, comprising the steps of:

a) preparing a mixture of enzyme compounds and water;

b) humidifying a fabric garment with said mixture;

c) placing the fabric garment in an industrial dryer and operating the industrial dryer for at least forty minutes at an activation temperature of the enzyme compound;

d) raising the temperature to at least ninety degrees Celsius for at least ten minutes in order to deactivate the enzyme;

e) rinsing the fabric garment until drosses, and mixture residues are not present in the fabric garment; and

f) drying the fabric garment;

wherein the step of humidifying a garment is done by spraying said mixture over it.

2. The method of claim 1 further comprising the step of preparing the fabric garment prior to the humidifying step by an action selected from the group consisting of manual abrasion, mechanical abrasion, laser abrasion, sandpapering, wearing, emery-polishing, and sandblasting.

3. The method of claim 1 further comprising the step of applying ozone to the fabric garment by passing the fabric garment through an ozone machine after the step of raising the temperature to at least ninety degrees Celsius.

4. The method of claim 1 further comprising the step of centrifuging the fabric garment before the step of placing the fabric garment in an industrial dryer, thereby removing any excess humidity.

5. The method of claim 1 wherein the step of humidifying the fabric garment occurs directly inside the industrial dryer.

6. The method of claim 1 further comprising the step of adding small abrasive bodies selected from the group consisting of rubber balls and plastic balls to the industrial dryer prior to operating the industrial dryer.

7. The method of claim 1 further comprising the step of maintaining a constant degree of humidity during the step of operating the industrial dryer.

8. The method of claim 1 further comprising the step of controlling the humidity by introducing a limited quantity of water in the industrial dryer.

9. The method of claim 1 further comprising the step of controlling the humidity by introducing a limited quantity of said mixture of enzyme compounds and water in the industrial dryer.

10. A method for artificially aging textile garments, especially cotton or denim garments, comprising the steps of:

a) preparing a mixture of enzyme compounds and water, the enzyme compounds chosen from the group consisting of Amylase, Cellulase and laccase;

b) humidifying a fabric garment with said mixture;

c) turning the fabric garment inside an industrial dryer capable of controlling its internal temperature for at least forty minutes at an activation temperature of the enzyme compound while keeping a degree of humidity constant;

d) raising the temperature of the machine to at least ninety degrees Celsius for at least ten minutes thereby deactivating the enzyme compounds;

e) rinsing the fabric garment until drosses, and mixture residues are removed; and

f) drying the fabric garment;

wherein the step of humidifying a garment is done by spraying said mixture over it.

11. The method of claim 10 further comprising the step of preparing the fabric garment by an action selected from the group consisting of manual abrasion, mechanical abrasion, laser abrasion, sandpapering, wearing, emery-polishing, and sandblasting prior to humidifying the fabric garment by spraying the mixture.

12. The method of claim 10 further comprising the step of applying ozone to the fabric garment by passing the fabric garment through an ozone machine after the step of raising the temperature of the machine to at least ninety degrees Celsius.

13. The method of claim 10 further comprising the step of centrifuging the fabric garment before the step of turning the fabric garment in an industrial dryer, thereby removing any excess humidity.

14. A method for artificially aging textile garments, especially cotton or denim garments, comprising the steps of:

a) spraying a mixture of enzyme compound and water on a fabric garment until the fabric garment is humidified in an industrial dryer and turning the fabric garment for at least forty minutes at an activation temperature of the enzyme compound;

b) raising the temperature of the industrial dryer up to at least ninety degrees Celsius for at least ten minutes thereby deactivating the enzyme compound;

c) rinsing the fabric garment until drosses, enzyme compound, and surfactant residues are removed from the fabric garment; and

d) drying the fabric garment.

15. The method of claim 14 further comprising the step of preparing the fabric garment prior to the step of spraying the fabric garment by an action selected from the group consisting of manual abrasion, mechanical abrasion, laser abrasion, sandpapering, wearing, emery-polishing, and sandblasting.

16. The method of claim 14 further comprising the steps of ozone cleaning and bleaching the fabric garment by passing the fabric garment through an ozone machine after the step of raising the temperature to at least ninety degrees Celsius.

17. The method of claim 14 further comprising the step of adding small abrasive bodies selected from the group consisting of rubber balls and plastic balls to the industrial dryer prior to operating the industrial dryer.

18. The method of claim 14 further comprising the step of maintaining a constant degree of humidity in the industrial dryer.

19. The method of claim 14 further comprising the step of controlling the humidity by introducing a limited quantity of water in the industrial dryer.

20. The method of claim 14 further comprising the step of controlling the humidity by introducing a limited quantity of said mixture of enzyme compounds and water in the industrial dryer.
