## Abstract

An elastic band for an article of clothing is described comprising an elongated strip-shaped outer layer of woven, longitudinally stretchable fabric, the outer layer being hydrophilic; an elongated strip-shaped inner layer of a different woven, longitudinally stretchable fabric the inner layer being hydrophobic and a logo woven into the fabric of the outer layer. Also disclosed is a double-layer construct for an elastic band comprising a hydrophobic section having apertures, a hydrophilic section having apertures, wherein the hydrophobic and hydrophilic sections are juxtaposed.

## Claims

### Claim 1

An elastic band for an article of clothing, comprising
an elongated strip-shaped outer layer of woven, longitudinally stretchable fabric having two transversely spaced longitudinally extending margins and an outer and an inner side, the outer layer being hydrophilic; and
an elongated strip-shaped inner layer of a different woven, longitudinally stretchable fabric the inner layer being hydrophobic, the inner layer extending along the inner side of the outer layer and being united with the inner layer at least along one of the longitudinally extending margins, the interlayer having an exposed inner side facing away from the inner side of the outer layer;

### Claim 2 (depends on 1)

An elastic band according to claim 1, further comprising a logo woven into the fabric of the outer layer.

### Claim 3 (depends on 1)

An elastic band according claim 1, wherein the outer and inner layers are interwoven at at least a portion of their interface.

### Claim 4 (depends on 1)

An elastic band according claim 1, the inner layer being composed at least in part of metal-, metal oxide-, and/or metal salt-containing yarn.

### Claim 5

A double-layer waistband comprising:
when in an un-folded configuration:
a hydrophobic section having a plurality of first apertures;
a hydrophilic section having a plurality of second apertures; and
an transition section between the hydrophobic section and the hydrophilic section, wherein the hydrophobic section, the hydrophilic section, and the transition section lie in a continuous plane.

### Claim 6 (depends on 5)

The double layer construct of claim 5, wherein the hydrophobic section comprises polypropylene yarn in combination with elastomeric yarn and the hydrophilic section comprises polyester, acrylic, viscose, cotton, wool or blended yarns thereof in combination with elastomeric yarn.

### Claim 7 (depends on 5)

The double layer construct of claim 5, wherein the hydrophobic section comprises metal-, metal oxide-, or metal salt-containing yarn.

### Claim 8

A double-layer construct for an elastic band, the construct comprising:
a hydrophobic section having a plurality of first apertures, the hydrophobic section having a first surface and an opposite second surface;
a hydrophilic section having a plurality of second apertures, the hydrophilic section having a third surface and an opposite fourth surface; and
wherein the first surface and third surface are juxtaposed.

### Claim 9 (depends on 8)

The double layer construct of claim 8, wherein the hydrophobic section comprises polypropylene yarn in combination with elastomeric yarn and the hydrophilic section comprises polyester, acrylic, viscose, nylon, cotton, wool or blended yarns thereof in combination with elastomeric yarn.

### Claim 10 (depends on 8)

The double layer construct of claim 8, wherein the hydrophobic section comprises metal-, metal oxide-, or metal salt-containing yarn.
