Description

[Detailed description of the invention] <Industrial application field> The present invention is a light-shielding and heat-retaining fabric made of a knitted fabric product in which a large number of narrow belt-like strips formed of synthetic resin film and aluminum foil are connected in a strip-like manner. Regarding blackout screens.

<Conventional technology> The conventional light-shielding screen is published under International Publication No. 1983.
No. 501,973, a number of longitudinally extending flexible strips are connected by transverse connecting threads and longitudinal connecting threads, the longitudinal connecting threads being between adjacent strips. The longitudinal connecting threads are located only on the underside of the strip near the gap, and the transverse connecting threads are located on the upper and lower sides of the strip and engage the longitudinal connecting threads on the underside of the strip to form a link. The threads and crosslinks are made of a material capable of absorbing water by capillary action.

<Problems to be Solved by the Invention> In the prior art described above, since the longitudinal connecting thread connecting the strips is located only on the lower side of the strips, the strips are brought into close contact with each other edge to edge. arranged to form an essentially uninterrupted connected surface. For this reason, air circulation is extremely poor, and water droplets are likely to form in a high-humidity room due to a drop in indoor temperature, etc. To prevent this, the longitudinal and horizontal connecting threads are made of a material that can absorb moisture by capillary action. However, it is not possible to sufficiently prevent the generation of water droplets on areas other than the screen, such as walls, ceilings, and pillars in the room. Therefore, it is necessary to place hygroscopic materials appropriately in the room and heat the indoor air to maintain a high temperature. There are some problems such as:

Another problem is that the strips are arranged closely together, making it difficult to fold and store compactly.

The inventor of this invention took into account the above-mentioned problems of the conventional technology, and aimed to provide a light-shielding screen that facilitates natural air circulation, prevents the generation of water droplets, and is easily foldable. The purpose is to

<Means for Solving the Problems> In order to achieve the above object, the present invention is a fine woven product in which narrow belt-like strips of aluminum foil backed and reinforced with a synthetic resin film are connected in a strip-like manner by warp and weft threads. In the light-shielding screen, a warp made of monofilament is positioned between adjacent strips to provide a small gap, and a weft made of monofilament placed above and below the strips is engaged with the warp to provide a rigid connection structure. The strip is connected to the connecting structure by a flexible thread-like body, and has an appropriate number of flexible parts formed at equal intervals and each having a space approximately the same width as the strip.

<Function> When the connecting structure 1 is applied to a greenhouse or the like, the inside of the room is kept in a suitable condition by the action of the synthetic resin film 2 and the aluminum foil 3 and the strip 4 which reflects and absorbs light and heat; Therefore, even if the indoor humidity increases, the small gaps 6 between the strips 4 allow natural air circulation, regulate the temperature, and prevent water droplets from forming.

In addition, since the adjacent strips 4 are rigidly connected by warp yarns 5 and weft yarns 7 made of monofilament, when stored, they are folded into an accordion shape by flexible portions 8 provided at equal intervals on the connecting structure 1, making it compact. can be stored in

<Example> Examples will be described with reference to the drawings.

As shown in FIG. 1, reference numeral 1 denotes a connecting structure forming the knitted or woven product of the present invention, and the connecting structure is made of a thin aluminum foil 3 backed and reinforced with a synthetic resin film 2 such as a polyester film or a polyethylene film. It has a large number of belt-like strips 4 (see Figure 3). On both sides of the strips 4 are placed warp yarns 5 made of lace-knit monofilament yarns, such as warp yarns 5, so that small gaps 6 are provided between each strip 4.

In addition, weft threads 7 made of monofilament similar to those described above are respectively positioned above and below the strip 4, and the weft threads 7 are knitted and engaged with the warp threads 5 on both sides of the strip 4, and each strip 4 is a rigid connecting structure. 1 is formed.

The connecting structure 1 is provided with a suitable number of flexible portions 8 having spaces approximately the same width as the strips 4 at equal intervals, and in the embodiment, flexible portions 8 are provided for every three strips 4. As shown in FIG. 2, the flexible portion 8 is formed by a flexible filament 9 such as a multifilament or spun yarn that connects the warp yarns 5, 5 located on both sides thereof, and the connecting structure 1 The flexible portion 8 allows it to be bent freely.

If the linked structure 1 having the above structure is cut to an appropriate width according to the purpose and applied to a greenhouse or the like, it can provide a light shielding effect as a light shielding screen, and the small gaps 6 between the strips 4 allow natural air circulation with the outside world. is performed to adjust the temperature, and each flexible portion 8 is folded into an accordion shape when stored.

<Effects of the invention> Since the present invention is configured as described above,
Small gaps are formed between each strip due to the presence of warp yarns, allowing air to circulate naturally with the outside world across the entire blackout screen, regulating indoor humidity and preventing water droplets from forming on walls, ceilings, columns, etc. when the indoor temperature drops. Since this prevents water from occurring, there is no need to make the warp and weft yarns from materials that can absorb water through capillary action, and instead, stiff monofilament yarns can be used to create a rigid structure, and moisture-absorbing materials can be placed inside the room. , there is no need to heat the air. Moreover, when stored, it can be easily folded into an accordion shape using the flexible parts provided with appropriate gaps, so it can be stored compactly without causing damage, and the shaded area can be minimized. It is extremely effective for shading and keeping heat in potted ornamental plants on balconies, wasabi cultivation, etc.
