## Abstract

Two-color net for protecting fruit against damage caused by direct solar radiation and high temperatures, used in combination and/or separately, which is made with two monofilaments that are pearl, blue or grey in color with a thickness of 0.26-0.32 mm.

## Claims

### Claim 1

A net for protecting fruit against damage caused by direct solar radiation and high temperatures, used in combination and/or separately, comprising two monofilaments in the colors pearl, blue or grey with a thickness of 0.26-0.32 mm.

### Claim 2 (depends on 1)

A net cloth for protecting fruit against damage caused by direct solar radiation and high temperatures, used in combination and/or separately according to claim 1, wherein the two monofilaments are used in a relation of 50:50 to make a shade cloth, with a weft density of 2.6-4.2 monofilaments/cm and a warp density of 2.6-4.2 monofilaments/cm.

### Claim 3 (depends on 1)

A net for protecting fruit against damage caused by direct solar radiation and high temperatures, used in combination and/or separately according to claim 1, wherein the shade cloth must be installed in orchards with 70%-80% light transmission.

### Claim 4 (depends on 1)

A process to make the net according to claim 1, comprising at least the following stages: (a) obtaining the monofilaments by extrusion, which involves the fusion of high-density polyethylene with pigments in a proportion of 2%-5% w/w in relation to the polymer and an anti-UV additive in a proportion equal to or greater than 0.6% w/w in relation to the polymer; and (b) weaving the monofilaments using flat looms with an English twist weave.

### Claim 5 (depends on 1)

A use of the net according to claim 1, to control sun damage in pome species by covering an area containing the pome species with the net according to claim 1.

### Claim 6 (depends on 1)

A use of the net according to claim 1, to control sun damage in fruit species by covering an area containing the fruit species with the net according to claim 1.

### Claim 7 (depends on 1)

A use of the net according to claim 1, to control sun damage in vegetables by covering an area containing the vegetables with the net according to claim 1.

### Claim 8 (depends on 1)

A use of the net according to claim 1, to control sun damage in vegetables, fruit species, pome fruit and leaf vegetables by covering an area containing the vegetables, fruit species, pome fruit and leaf vegetables with the net according to claim 1.

### Claim 9 (depends on 5)

The use of the net according to claim 5, wherein the pome species is selected from the group consisting of apples and pears.

### Claim 10 (depends on 6)

The use of the net according to claim 6, wherein the fruit species is selected from the group consisting of grapes, kiwis and pomegranates.

### Claim 11 (depends on 7)

The use of the net according to claim 7, wherein the vegetables are selected from the group consisting of tomatoes and peppers.
