Sun protection fabric

Abstract

To provide a sun protection fabric. [Solution] A sun protection fabric 10 is made from a highly flexible radiative cooling sheet, and is reinforced with a peripheral edge 6 as needed, can be tightened with a string, and is equipped with a fastener to keep the fabric wrapped stably. This allows it to flexibly accommodate various small items carried or accompanied by someone, small pets such as dogs and cats, etc., even in high temperatures, especially under the scorching sun of midsummer, by wrapping them flexibly and smoothly along the objects, protecting them from the heat.

Description

Technical Field

[0001] The present invention relates to a solar protection fabric that can be freely adjusted.

Background Art

[0002] In recent years, various radiative cooling materials have emerged. Sheet materials are used to cover the outer surface of the roof of an automobile, which becomes hot under the scorching sun, or the roof of a building, or are held around a framework or frame of a predetermined shape such as an umbrella, tent, or curtain, and various products suitable for respective purposes have been proposed. However, since their shapes are fixed, there is no product that can quickly respond to various items such as small portable coolers, infants taken out, small animals such as dogs and cats, and food and drinks carried, and protect them from the sunlight pouring down under the scorching sun, and such a product has been desired.

Problems to be Solved by the Invention

[0004] The present invention aims to provide a solar protection fabric that can flexibly and smoothly wrap around small items carried during movement, infants, and pet animals such as dogs and cats, which cannot be fully covered by the prior art, with a simple structure, and stably maintain that state to respond to them.

Means for Solving the Problems

[0005] To achieve the above object, the present invention cuts a sheet-shaped radiative cooling material that can be freely folded into a predetermined size to form a solar radiation shielding fabric 10, and reinforces the periphery at the peripheral edge 6 as needed as shown in FIG. 1. As shown in FIG. 6, if the inside of the peripheral edge 6 is made to communicate and a string 7 is passed through the inside, the peripheral edge 6 can be tightened to be used in a bag shape. Further, instead of the string 7 to be inserted, if fixing tools 9 such as a tying string, a planar fastener, a hook, a button, and a peg are provided at appropriate positions on the peripheral edge 6, the fixing tools 9 can be fastened to each other, or the fixing tool 9 can be fastened to a fixed part such as the ground, and it can be used without being blown away even when the wind blows.

[0006] The solar radiation shielding fabric 10 is generally a material called a radiative cooling material. The radiative cooling material has a heat insulation function (reflectivity of 95% or more) that blocks sunlight and suppresses heat absorption, and a radiative cooling function (emissivity of 95% or more) that increases infrared rays in the wavelength range of the "atmospheric window" and emits heat into the universe by radiating. A radiative cooling material that combines both functions or a Radicool canvas can be adopted.

[0007] That is, here, as the radiative cooling material, a radiative cooling material (for example, a Radicool canvas) that combines a heat insulation function (reflectivity of 95% or more) that blocks sunlight and suppresses heat absorption, and a radiative cooling function (emissivity of 95% or more) that increases infrared rays in the wavelength range of the "atmospheric window" and emits heat into the universe by radiating can be adopted. And this material sets a heat insulation function surface (reflectivity of 95% or more) that blocks sunlight and suppresses heat absorption and a radiative cooling function surface that increases infrared rays in the wavelength range of the "atmospheric window" and emits heat into the universe by radiating on the outer surface so as to block sunlight.

[0008] Figure 3(a) shows that small items to be carried, such as a cooler box 11, are wrapped from above and outside by the solar radiation shielding fabric 10. (b) shows that it is placed on the solar radiation shielding fabric 10 like a furoshiki and the periphery is tightened and covered. In either case, even under the scorching sun, the cooler box 11 is prevented from becoming abnormally hot due to sunlight, suppressing the progress of deterioration of the contents due to heat. Similarly, small animals can be wrapped to protect them from heatstroke and sunstroke in the same way. The same applies to infants. For animals, for example, as shown in Figure 7, the solar radiation shielding fabric 10 is put on the back of a puppy, and a stopper 9 like a string is connected to hold the wrapped state.

[0009] Figure 2 shows an example of the solar radiation shielding fabric 10 made of a radiative cooling material used in the present invention. On the base fabric 1, a functional layer 3 having both reflection + radiative cooling functions is laminated via a primer 2, and if necessary, a top coat 4 is laminated on its outer layer. It is a single flexible fabric, and the functional layer 3 and the top coat 4 are used so that they are on the outside as shown in the figure, and when not in use, it can be folded compactly like a furoshiki.

[0010] Figure 4 shows that a string 7 is connected to the peripheral part 6 so that it can be tightened. Figure 5 shows that eyelets 8 are provided at a plurality of locations on the peripheral part 6 to form a string-like stopper 9, and the object is wrapped and held in that state by the stopper 9. Figure 7 shows that the back of a puppy is wrapped with the solar radiation shielding fabric 10 to protect it from sunlight.

Advantages of the Invention

[0011] As described in detail above, the solar radiation shielding fabric 10 of the present invention is formed of a radiative cooling material, is usually folded compactly, and is unfolded when necessary to wrap, for example, a portable cooler box 11, electronic devices, food and beverages, the whole or necessary parts of infants and small animals, and prevents overheating due to sunlight irradiation under the scorching sun.

[0012] And particularly in the present invention, the solar radiation shielding fabric 10 is not restricted in its outer shape or the like by a framework, a frame, or the like in advance. When necessary, it can closely adhere to the object and exert its cooling effect, and when not in use, it can be compactly stored like folding a furoshiki.

[0013] Furthermore, if a string 6 is passed through the peripheral edge 5 as needed, it can reinforce the periphery and improve durability. If the string 6 can be tightened, the solar radiation shielding fabric 10 can expand and contract according to the size of the wrapped object and be closely adhered, and it can also be stabilized without being blown away by wind or the like.

[0014] In addition, fixing tools 9 such as tying strings, surface fasteners, hooks, and buttons can be provided at appropriate positions on the solar radiation shielding fabric 10.
