## Abstract

A woven fabric material including an array of machine direction yarns and cross-machine direction yarns. The array includes larger denier yarns arranged in an alternating pattern with smaller denier yarns in both the machine direction and the cross-machine direction. The array of machine direction yarns and cross-machine direction yarns is arranged to allow water to pass freely through the woven fabric material.

## Claims

### Claim 1

A pool cover comprising:
a single set of a first alternating pattern of monofilament yarns in a machine direction and a second alternating pattern of monofilament yarns in a cross-machine direction,
wherein the first alternating pattern comprises smaller monofilament yarns and larger monofilament yarns,
wherein the second alternating pattern comprises smaller monofilament yarns and larger monofilament yarns,
wherein the larger monofilament yarns are of larger denier than the smaller monofilament yarns,
wherein the pool cover has a lower density than water, and
wherein gaps between the monofilament yarns allow water to pass freely therethrough.

### Claim 2 (depends on 1)

The pool cover of claim 1, wherein the larger monofilament yarns of the first and second alternating patterns are of the same denier size, and smaller monofilament yarns of the first and second alternating patterns are of the same denier size.

### Claim 3 (depends on 1)

The pool cover of claim 1, wherein the larger monofilament yarns of the first and second alternating patterns are of different denier sizes, and the smaller monofilament yarns of the first and second alternating patterns are of different denier sizes.

### Claim 4 (depends on 1)

The pool cover of claim 1, wherein the first alternating pattern comprises 525 denier yarns and 1000 denier yarns.

### Claim 5 (depends on 1)

The pool cover of claim 1, wherein the second alternating pattern comprises 565 denier yarns and 925 denier yarns.

### Claim 6 (depends on 1)

The pool cover of claim 1, wherein the first alternating pattern comprises at least thirty-six smaller monofilament yarns for every two larger monofilament yarns and the second alternating pattern comprises at least eighteen smaller monofilament yarns for every two larger monofilament yarns.
