Description

The present invention relates to an attraction string used for climbing plants.

Strings such as hemp rope and stainless steel are known as attracting strings for attracting vegetables such as cucumber, pea, bitter gourd, flowers such as morning glory, and vines such as houseplants such as ivy.
In particular, in recent years, green curtains using climbing plants have been increasingly installed in houses and buildings due to factors such as the urban heat island phenomenon and global warming.
In this case, strings using natural fibers such as hemp or synthetic resin tapes are used.However, in large facilities such as buildings, the length of the attracting string is long, so it depends on the weight of the attracting string, the mass of the plant, and the wind. Since a tensile strength with respect to a tension or the like is required, an attracting cord using a steel material such as stainless steel has been used.
Further, an attraction string which is more suitable for growing plants by combining a steel wire with a fiber having hydrophilicity such as carbon fiber is also known. (Patent Document 1)

Then, while having sufficient intensity | strength, this invention suppresses the temperature rise of an attraction string even if it is exposed to sunlight during the daytime, and it aims at providing an attraction string suitable for growing a vine. I have.

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above problems, and as a result, have accomplished the present invention.
That is, the present invention has the following configurations [1] to [5].
[1] The attraction string of the present invention is an attraction string used for growing a climbing plant, and is formed by using a high-strength fiber as a core material and coating the periphery of the core material with a synthetic fiber.
With the configuration of the present embodiment, since the high-strength fiber is used for the core material, the strength of the attraction string is improved, and particularly a long attraction string is required. For example, the attraction for a green curtain such as a building. It can be used as a string and can be used as a greening material for building walls.
In addition, by coating the high-strength fiber with a synthetic fiber, the fiber can be colored in an arbitrary color, and can be colored according to the place where the attracting string is used, such as a building, to enhance the design.
Also, when carbon fiber is used as the attraction string, the carbon fiber is generally black and absorbs sunlight and heat energy from the road surface to increase the temperature of the carbon fiber. Although there is a possibility of weakening, it is possible to suppress an increase in the temperature of the carbon fiber by coating with the synthetic fiber.

[2] The attraction string according to the above [1], wherein the synthetic fiber has water absorbency.
Since the synthetic fiber has water absorbency, the vaporization of water contained in the synthetic fiber suppresses an increase in the surface temperature of the attraction string, which is preferable from the viewpoint of growing vines. Further, the water contained in the synthetic fibers can be absorbed by plants, which is preferable from the viewpoint of growing vines.

[3] The attracting cord according to the above [1] or [2], wherein the core material contains a water-absorbing fiber.
By including the water-absorbing fiber as the core material, the amount of water contained in the attracting string increases, so that the temperature rise of the attracting string can be suppressed for a long time. In addition, moisture can be supplied to the vine over a long period of time.
When the synthetic fiber constituting the surface of the attraction string has a water absorbing property, the water held by the water-absorbing fiber contained in the core material is supplied to the synthetic fiber constituting the surface of the attraction string, and the attraction string is provided. This is preferable because the increase in the surface temperature of the vine can be suppressed and moisture can be supplied to the vine.

  Further, when the synthetic fibers constituting the surface of the attraction string are made hydrophobic, the water of the water-absorbing fibers contained in the core material is suppressed from migrating to the synthetic fibers constituting the surface of the attraction string, and It is possible to suppress a decrease in water inside. Therefore, it is preferable that the vine can extend the roots through the gaps of the synthetic fibers forming the surface layer to the core material and receive water from the water-absorbing fibers of the core material for a long period of time. In addition, although the effect of suppressing the temperature rise may be slightly reduced as compared with the synthetic fiber forming the surface of the attraction string having water absorption, the temperature increase of the attraction string may be suppressed for a longer period. it can.

[4] The attracting cord according to any one of [1] to [3], wherein the high-strength fiber includes a carbon fiber.

  Hereinafter, preferred embodiments of the present invention will be described. However, it is understood that the present invention is not limited to only these embodiments, and that many modifications are possible within the spirit and scope of the present invention. I want to. In the present invention, the fiber includes a fiber bundle such as a thread-like material obtained by bundling fibers.

The attraction string of the present invention is an attraction string used for growing a climbing plant, and is formed by using a high-strength fiber as a core material and coating the periphery of the core material with a synthetic fiber.

High-strength fibers include carbon fiber, basalt fiber, para-aramid fiber, meta-aramid warfare, ultra-high molecular weight polyethylene fiber, polyarylate fiber, polyparaphenylenebenzoxazole (PBO) fiber, polyphenylene sulfide (PPS) fiber, Polyimide fiber, fluorine fiber, polyvinyl alcohol (PVA) fiber, polyacetal fiber and the like are used. By using this high-strength fiber, it is excellent in tensile strength, lighter and more rust-resistant than iron or the like, and more excellent in corrosiveness than natural fibers such as hemp.
From the viewpoint of suppressing an increase in the temperature of the attraction string, carbon fibers having excellent thermal conductivity are preferable.

Preferably, the core material contains water-absorbing fibers. By including the water-absorbing fiber in the core material, the amount of water retention of the attraction string increases, and the temperature rise of the attraction string can be suppressed for a long time. In addition, moisture can be supplied to the vine over a long period of time.
More specifically, when the synthetic fibers constituting the surface of the attracting string to be described later have a water absorbing property, the moisture held by the water absorbing fibers contained in the core material is applied to the surface of the attracting string. It is preferable because it can be supplied to the constituent synthetic fibers to suppress a rise in the surface temperature of the attracting string for a long period of time and to supply water to the vine.
Further, when the synthetic fibers constituting the surface of the attraction string are made hydrophobic, the water of the water-absorbing fibers contained in the core material is suppressed from migrating to the synthetic fibers constituting the surface of the attraction string, and the core material is prevented. It is possible to suppress a decrease in water inside. Therefore, it is preferable that the vine can extend the roots through the gaps of the synthetic fibers forming the surface layer to the core material and receive water from the water-absorbing fibers of the core material for a long period of time. In addition, the effect of suppressing the temperature rise against heat rays from sunlight, a road surface or the like may be slightly reduced as compared with the synthetic fiber constituting the surface of the attracting string having a water absorbing property. It is possible to suppress the temperature rise from the part, and to suppress the temperature rise of the inducing string for a longer period.

Examples of the water-absorbing fiber include natural fibers such as cotton and hemp, regenerated fibers such as rayon, and synthetic fibers having a water-absorbing property.For example, a water-absorbing resin such as a water-absorbing polyester resin is applied to polyester fiber. And those obtained by polymerizing a hydrophilic monomer on the fiber surface, and those obtained by spinning a hydrophilic polyester resin. Further, a polyester fiber may be hollowed out to give water absorption by a capillary phenomenon.
In addition, other hydrophobic fibers and the like may be used in combination with the core material from the viewpoint of improving water transferability and water retention without departing from the intended purpose of the present invention.

  When other fiber materials such as high-strength fiber and water-absorbent fiber are used in combination, they may be randomly compounded in a state parallel to the fiber axis direction of the high-strength fiber and the axial direction of the water-absorbent fiber. May be arranged so as to cover the periphery with water-absorbing fibers or the like. The high-strength fiber may be wound around the spiral with water-absorbent fiber to cover it, or the high-strength fiber may be wrapped around the high-strength fiber to form a high-strength fiber inside the braid made of water-absorbent fiber. May be arranged.

(Synthetic fibers)
The synthetic fiber used for coating around the core material of the present embodiment constitutes the surface of the attracting cord. Examples of the synthetic fibers of the present embodiment include synthetic fibers such as polyester, nylon, polyacryl, polypropylene, vinyl chloride, aramid, polyamide, and polyacetal.
In the case of a synthetic fiber, the surface of the attracting string is less likely to reach a high temperature than a metallic attracting string, and is superior in weather resistance compared to a natural fiber. Further, it is preferable because arbitrary properties such as water absorption and flame retardancy can be easily provided, and polyester fiber is particularly preferable. In addition, if it is a synthetic fiber, it can be easily colored, and can be colored in an arbitrary color in consideration of the wall surface of the building using the attraction string and the surrounding environment, and is excellent in design. Polyester fibers are preferable also from the viewpoint of light resistance of coloring.

Further, the synthetic fiber may be one having water absorbency or one having hydrophobicity, but a synthetic fiber having water absorbency is preferable. If the attracting string is heated by heat rays such as sunlight when the synthetic fiber has water absorbency, the latent heat of water contained in the synthetic fiber suppresses the temperature rise of the attracting string, particularly the surface temperature, and It is preferable from the viewpoint of suppressing damage to plants due to heat. In addition, moisture can be supplied to the vine from the surface of the attraction string.
In addition, when rain or the like falls, it is preferable from the viewpoint that the rain can be absorbed and water can be supplied to the core material, particularly the water-absorbing fibers of the core material.

  Examples of the synthetic fibers having water absorbency include those obtained by adding a water-absorbent resin such as water-absorbent polyester to synthetic fibers and those obtained by polymerizing a hydrophilic monomer on the fiber surface. Moreover, what spun hydrophilic resin can also be mentioned. Further, a synthetic fiber may be hollowed out to impart water absorption by capillary action.

Further, it is preferable that the attracting cord of the present embodiment is white or light-colored. If the color is white or light, it reflects heat rays such as sunlight and can suppress the temperature rise of the attraction string. The light color is not particularly limited, and may be any light color such as pink, light blue, green, and gray.
In addition, it is preferable from the viewpoint of designability to color green, yellow, red, or the like in accordance with the color of leaves, stems, or flowers of the vine used. In particular, those colored green are preferable.

The film may be covered with a film or the like to give coloring or protection. The resin film in this case may or may not have hydrophilicity or water permeability. However, it is preferable that the resin film has water permeability from the viewpoint of growing vines and suppressing the temperature rise of the attracting string.

Hereinafter, the present invention will be described in more detail with reference to Examples. Note that the present invention is not limited to the following embodiments.
In addition, the temperature of the attraction string in this example was measured by the following method.
A sample having a length of 20 cm was prepared, and a thermocouple was attached to the center of the sample (at a position 10 cm from the end of the sample). The thermocouple was covered with aluminum foil so that light from a beam lamp did not directly hit the sample. A sample is placed on a sample stand having heat insulation, and a beam lamp (manufactured by Toshiba Lighting & Technology Corp .; BRF110V, 120W) is set at a distance of 25 cm from the center of the sample (the mounting position of the thermocouple). A beam lamp was irradiated from above the sample placed on the table, and the temperature of the sample was measured after 60 minutes.
The room temperature during the test was 25 ° C.

(Example 1)
A bundle of 24K carbon fibers (PAN-based carbon fiber; T700SC, manufactured by Toray Industries, Inc.) was used as the high-strength fiber, and the bundle of carbon fibers was used as a core material. In addition, using a white water-absorbent polyester fiber yarn (500 decitex, multifilament yarn) treated with a water-absorbent polyester resin, the entire surface around the core material is covered with a polyester fiber in a braided shape by perforation, An attracting cord for a vine having a diameter of about 3 mm (measured on a steel scale) was obtained.

For the obtained inducing string, suspend the thing not containing water (dry matter) and the inducing string, supply water to the inducing string from the upper part, and stop supplying water. Then, supply water from the lower part of the inducing string. The temperature was measured using a sample (droplet containing water) from which the dropping was stopped as a sample.
As a result, the temperature of the dried product was 32 ° C. and that of the product containing water was 26 ° C. When a temperature was measured on a stainless steel rod (dry product) having a diameter of 3 mm by the same method, the temperature was 34 ° C.
From this result, the attracting cord of the present example has a lower temperature, a superior temperature rise suppressing effect, and a superior plant planting effect, compared with a stainless steel rod of the same thickness as 2 ° C. for a dried material and 8 ° C. for a material containing water. It was confirmed that it was a favorable attraction string in terms of breeding.

The attracting cord of the present invention uses a high-strength fiber as a core material, and thus has excellent tensile strength, from a vegetable garden in a general house, from a attracting cord in a flowerbed, to an attracting cord for a farm, and a large size such as a building. It can also be used as an attraction string for greening walls of buildings.
Also, since the periphery of the core material is covered with synthetic fibers, the core material can be colored in any color, and is excellent in design.
In addition, it suppresses a rise in the temperature of the attraction string due to heat rays from sunlight or the like, which is preferable for growing vines. Therefore, it can be widely used as an attraction cord for vegetable gardens and greening of building walls.
