Abstract

This invention relates to a moisture management fabric and methods of producing such a fabric. In some embodiments, the moisture management fabric is a multi-layered fabric comprising an inner layer, and intermediate layer and an outer layer. In other embodiments the fabric is one or two layers. In some embodiments, the inner layer comprises a fabric treated with a nanoparticle dispersion. In some embodiments, the intermediate, inner, or single layer comprises a hydrophilicity gradient. In some other embodiments, the outer layer comprises at least one nanofiber.

Claims (15)

1. A moisture management garment, a cross-section of said garment comprising:

(a) a inner layer comprising hydrophobic titanium dioxide nanoparticles;

(b) a middle layer comprising carboymethylated hydrophilic fibers abutting said first layer, wherein the hydrophilicity of said middle layer decreases across said middle layer in the direction of said first layer; and

(c) an outer layer comprising hydrophilic chitin or chitosan nanofibers, abutting said middle layer on the side of said middle layer opposite said first layer, said outer layer being more hydrophilic than said first layer;

wherein the decrease in hydrophilicity of said middle layer in the direction of said first layer is caused by a gradient in the concentration of a chemical agent across said middle layer.

2. The moisture management garment of claim 1 wherein the garment is a shirt.

3. The moisture management garment of claim 1 wherein the garment is a skirt.

4. The moisture management garment of claim 1 wherein the garment is a dress.

5. The moisture management garment of claim 1 wherein the garment is shorts.

6. The moisture management garment of claim 1 wherein the garment is pants.

7. The moisture management garment of claim 1 wherein the garment is underwear.

8. The moisture management garment of claim 1 wherein the garment is a wristband.

9. The moisture management garment of claim 1 wherein the garment is a headband.

10. The moisture management garment of claim 1 wherein the garment is a sock.

11. The moisture management garment of claim 1 wherein the garment is footwear liner.
