Abstract

The present disclosure relates to methods for distressing an object by projecting polysaccharide particles onto a surface of the object. The present disclosure relates also to methods for cleaning the distressed fabric or garment and optionally methods for recycling the polysaccharide particles. In one embodiment, a method for distressing an object comprises suspending polysaccharide particles in a gas, creating a suspension, and projecting the suspension onto an object.

First claim

The invention claimed is:

1. A method for distressing a fabric or a garment, the method comprising:
suspending polysaccharide particles having a moisture content ranging from about 10% to about 15% in a gas, creating a suspension;
projecting the suspension onto a surface of the fabric or the garment at a pressure ranging from about 69 kPa to about 207 kPa; and
removing the polysaccharide particles from the fabric or the garment with water or an aqueous solution, thus degrading starch in the polysaccharide particles;
wherein the polysaccharide particles have a Mohs hardness of at least 1.5 and are water soluble;
wherein the polysaccharide particles comprise a dye and form a polysaccharide dye complex.

2. The method according to claim 1 , wherein the polysaccharide particles are pregelatinized.

3. The method according to claim 1 , wherein the polysaccharide particles comprise glass-like polysaccharide abrasive grit.

4. The method according to claim 1 , wherein the polysaccharide particles comprise starch.

5. The method according to claim 1 , wherein the method removes a fiber, a part of the fabric or the garment, or a combination of any thereof.

6. The method according to claim 5 , wherein the fiber or the part of the fabric or the garment comprises a dye.

7. The method according to claim 1 , wherein the polysaccharide particles are characterized by a specific density ranging from about 1.0 g/cm 3 to about 2.0 g/cm 3 .

8. The method according to claim 1 , wherein the polysaccharide particles have a particle size ranging from about 177 μm to about 2000 μm.

9. The method according to claim 1 , wherein the polysaccharide dye complex comprises a fluorescent agent.

10. The method according to claim 1 , further comprising re-projecting the polysaccharide particles onto the fabric or the garment.

11. The method according to claim 10 , wherein the polysaccharide particles are re-projected onto the fabric or the garment from about 15 times to about 30 times.

12. The method according to claim 10 , wherein the polysaccharide particles are re-projected until the particle size reaches an average particle size of about 125 μm or less.

13. A method for distressing furniture, the method comprising:
suspending polysaccharide particles having a moisture content ranging from about 10% to about 15% in a gas, creating a suspension; and
projecting the suspension onto a surface of the furniture at a pressure ranging from about 69 kPa to about 207 kPa;
wherein the polysaccharide particles have a Mohs hardness of at least 1.5;
wherein the polysaccharide particles comprise a dye and form a polysaccharide dye complex.

14. A method for distressing a fabric or a garment, the method comprising:
suspending polysaccharide particles and another abrasive grit in a gas, creating a suspension; and
projecting the suspension onto a surface of the fabric or the garment;
wherein the another abrasive grit is selected from the group consisting of aluminum oxide, silica, sand, agricultural residues, acrylates, and combinations of any thereof;
wherein the polysaccharide particles comprise a dye and form a polysaccharide dye complex.
