Description

[Detailed description of the invention] This invention relates to a shading net for agriculture and horticulture.

This invention provides a shading net for agriculture and horticulture that has light-shielding properties, reflective properties, heat retention, breathability, water droplet permeability, insect-proofing properties, bird-proofing properties, round thickness, elasticity, lightness, and toughness. It is something to do.

In other words, this invention consists of a vapor-deposited tape made by folding a plastic tape of several millimeters to several centimeters in length in half or four in the direction of the center, and a vapor-deposited tape of several millimeters or more that is colored black.
A woven or knitted fabric is formed by folding a few centimeters of plastic tape in two or four in the middle direction and using it in a polymerized state in the vertical and/or horizontal direction. This is a light-shielding net for agriculture and horticulture, which is characterized by having black tape exposed on one side of the tape.

This invention first uses a plastic tape of a few millimeters to a few centimeters in size and is coated with metal dust, and then folds it in half or four in the middle direction to give it thickness, roundness, and elasticity. Form the tape.

The thickness, roundness, and elasticity result from the fact that the plastic film itself has a certain degree of flexibility and restoring force. As the plastic film, polyester and other various plastic films can be used. AI, Cr, Ni, Ag, Cu, and various other metals can be used for the metal vapor deposition layer. It is free to provide a protective layer as appropriate on the metal coating layer, or to color the plastic film or protective layer as appropriate. Before the vapor-deposited tape is folded in two or four in the middle direction, the width is from several millimeters to several centimeters, but after it is folded in the middle direction, the width becomes 1 mm to 5 mm.

Next, use black colored plastic tape,
This is folded in half to four in the middle direction to form a thick, rounded and elastic black tape.

The inside of the black tape is about the same size as the inside of the vaporized tape.
As the plastic film in this case, polyester and other various plastic films can also be used. Then, the vapor-deposited tape and the black tape are used in a polymerized state in the vertical or horizontal direction, or in both directions to form a woven or knitted fabric, with the vapor-deposited tape on one side of the woven or knitted fabric and the black tape on the other side. to appear.

In the thus obtained product of the invention, the side on which the vapor-deposited tape is exposed has a metallic color, and the side on which the black tape is exposed is black. how to spell,
Examples of weaving methods include making a raschel line using vapor-deposited tape and black tape together with other thin threads, plain weaving it together with other suitable plastic threads such as fan flat thread, gold and silver thread, and thin medium tape, Plain weaving can also be carried out using vapor-deposited tape and black tape in both the direction and the transverse direction.

Furthermore, the vapor-deposited tape and the black tape may not be formed in advance, but may be formed in the process of manufacturing woven or knitted fabrics. Can be used as appropriate.

The method of use depends on the purpose and use, for example, covering directly on ridges or other surfaces, covering facilities for raising seedlings, cultivation frames, etc.
You are free to use it in whole or in part for tunnels, houses, etc. In addition, the use condition is that the vapor-deposited tape side is exposed to light and the black tape side is facing the soil.
It has excellent bird-proofing properties and is made of light material, making it extremely lightweight and convenient to handle and transport.

Furthermore, since it is a woven or knitted fabric, it has good air permeability and permeability to water droplets, and can always maintain an appropriate amount of air and moisture.

Also, since it is a woven or knitted fabric, it has a strong axis against forces in both the vertical and structural directions. Furthermore, this invention uses Aoiku tape and black tape that are folded in two to four in the middle direction.The thickness, roundness and elasticity of the tape makes the entire light-shielding net extremely thick. have

And because each evaporated tape has a thickness or roundness, unlike a simple fan-flat tape, the light rays are not reflected uniformly, but diffusely reflected in all directions, making it function extremely effectively. For example, ``The light-shielding net of this invention can be used to insulate the soil and at the same time reflect light from below to crops.''
When shining on plants, the reflected light hits the crops and plants from all angles, not just one direction.
It is extremely beneficial to plants. Furthermore, in this invention, the thick, round and elastic black tape is folded in two to four and is woven in a state where it is polymerized with the vapor-deposited tape, resulting in the following effects.
