Description

Biodegradable vegetation bag

The present invention relates to a vegetation bag that is installed on the slope of the road cutout, the reservoir around the river, the embankment, and the like, and exhibits various control functions such as soil erosion prevention and slope loss prevention.

Generally, slopes, river slopes, erosion sites, and reservoirs suffered from natural disasters or artificial damages may cause collapse or soil loss due to erosion.

In order to prevent this problem, to make a grid-shaped frame using concrete, PVC, wire mesh, etc., filling the soil between them sowing plant seeds, such as vegetation and grass seeds, or transplanting grass, natural fiber There is a method for installing vegetation and spraying (seed-spraying) grasses to allow vegetation to germinate and stick, thereby preventing erosion and collapse due to the binding force of the roots. All of these methods work when there is soil or other accessible soil base material that will form the vegetation zone. This is impossible. Therefore, in such an environment, a method is applied to a vegetation plant attached to a vegetation bag attached to plant seeds so that soil plants such as soil, sand or martha can be approached.

1 is a perspective view showing a conventional vegetation bag. Referring to FIG. 1, the vegetation bag 10 has an inner space 1 in which a plant seed 3 can fill a soil base material that can germinate. The sheath of the vegetation bag is formed by cutting a woven fabric, which is made of warp yarns 5 and weft yarns 7 as is known. The warp yarn 5 and the weft yarn 7 may use synthetic fibers such as polypropylene or polyester, but since the general synthetic fiber does not decompose for a long time and destroys the environment, the warp yarn 5 and / or the weft yarn 7 Natural fibers such as hemp fibers or biodegradable fibers such as biodegradable synthetic fibers modified to be decomposed within a certain period of time in nature are produced. The inner surface of the fabric is attached to the endothelium 9 carrying plant seeds 3. FIG. 2 is a cross-sectional view of one surface of the vegetation bag of FIG. 1. The endothelium 9 inserted into the outer shell made of fabric is composed of a first endothelial 9a and a second endothelial 9b made of sheet-shaped paper, and between the first endothelial 9a and the second endothelial 9b. Many plant seeds 3 are stored. Endothelial 9 is sewn on the edge of the vegetation bag 10 is fixed to the outer shell. As described above, the vegetation bag 10 having the inner surface of the sheet 3 having the plant seeds 3 formed on the inner surface of the sheet-shaped paper has a disadvantage in that the endothelial is easily torn off when the soil base material is filled in the bag with a shovel or the like. As the endothelium 9 is torn out, the plant seeds 3 stored therein are also swept away, so that the germination distribution of the plant seeds on the surface of the vegetation bag is uneven, so that the function of the vegetation bag is not smoothly performed. In addition, such a method requires a lot of plant seeds and paper than necessary, so there is a problem that a lot of manufacturing costs.

The present invention has been conceived to improve the above problems, the plant seeds are durable and can be germinated uniformly on the front of the bag and can be easily mass-produced with a weaving machine, very economical, microorganisms over time The purpose is to provide a vegetation bag that can be biodegraded by to prevent environmental pollution.

In order to achieve the above object, the present invention has an interior space for filling the soil base material, and is a vegetation bag formed of a woven fabric of warp or weft yarn made of biodegradable fibers, wrapped with a plurality of plant seeds in paper The provided filament yarns provide vegetation sacks inserted into the fabric at predetermined intervals as warp or weft yarns.

In the vegetation bag according to the present invention, it is preferable to use hemp fiber which is a natural fiber having excellent physical properties as a biodegradable fiber.

According to the vegetation bag of the present invention, the filament yarn wrapped inside the plant seeds wrapped in paper weaved as the warp or weft of the fabric, so that the filament yarn wrapping the plant seeds when filling the soil base material is not easily destroyed as well as plant seeds Germinate evenly on the front of the bag. In addition, the weaving machine can be easily mass-produced, very economical, and biodegradable by microorganisms over time, thereby preventing environmental pollution.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3 is a perspective view schematically showing a vegetation bag in a first preferred embodiment of the present invention.

Referring to FIG. 3, the vegetation bag 20 according to the first embodiment of the present invention includes an inner space 11 capable of filling a soil base material. Vegetation sacks 20 are formed by cutting a woven fabric, which is woven from warp yarns 15 and weft yarns 17 made of biodegradable fibers. The warp yarn 15 and the weft yarn 17 may use synthetic fibers such as polypropylene or polyester, but vegetation bags formed of a fabric woven from conventional synthetic fibers do not decompose for a long time and thus destroy the environment. Biodegradable fibers such as natural fibers such as hemp fibers or known synthetic fibers modified to be decomposed by microorganisms within a certain period of time are used. In particular, hemp fibers have excellent physical properties and are relatively inexpensive, and thus are suitable as weaving yarns of vegetation bags. Of course, it is also possible to replace some of the warp yarn 15 and the weft yarn 17 with synthetic fibers as necessary.

In Fig. 1, the filament yarn 19, which wraps a large number of plant seeds in paper and is stored in the fabric forming the vegetation bag 20 of the present invention, is inserted at predetermined intervals as a weft yarn. Conventionally, plant seeds are stored on a sheet-shaped paper inner surface to be fixed to a fabric envelope, and when the soil base material is filled with a shovel in a vegetation bag, the inner skin is easily torn off, but the present invention wraps the plant seeds with paper to store the filament inside. Since the yarns 19 are formed and used as warp or weft yarns, there are almost no such problems and can be easily mass-produced. In addition, since the filament yarn 19 is used only for some warp or weft of the fabric, only an appropriate amount of plant seeds and paper can be used to reduce manufacturing costs.

4 is a state diagram schematically illustrating a state in which plant seeds are stored in the filament yarn 19. Referring to FIG. 4, the filament yarn 19 is manufactured by arranging a plurality of plant seeds 13 in a long paper and then twisting them. The reason why the filament yarn 19 is combustible is that the stored plant seeds 13 are not allowed to escape from the inside of the paper filament yarn 19, and the filament yarn 19 can be used as a weft yarn to be woven. To maintain strength. Therefore, if the plant seeds 13 are stably stored in the filament yarn 19, the plant seeds 13 can be stably stored and woven in a manner such that the outer part of the paper is treated with an adhesive such that the plant seeds 13 stored in the filament yarn 19 do not escape. The flammable treatment may be omitted. In addition, the filament yarn 19 in which the plant seeds 13 are stored may be used as a ramp instead of the weft of FIG. 4, and may be used simultaneously as a warp and weft. The frequency of use of the filament yarn 19 with the plant seeds 13 and the warp yarn 15 and the weft yarn 17 made of biodegradable fibers can be used to fill the vegetation bag 20 with soil base material to withstand transportation. It is freely adjustable as needed within the limits of the degree. Paper of the filament yarn 19 in the present invention is made of pulp, not only can be used as the weft or warp of the fabric, it is also easily destroyed by moisture, so that the germination and growth of the plant seed (13).

When the soil base metal is used to fill the vegetation sacks 20 of the present invention prepared by the above-described method, plant seeds germinate with a uniform distribution as shown in FIG. 5 and have a beautiful appearance. Is also maximized.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, the vegetation bag according to the present invention wraps the plant seeds in paper so that the filament yarns stored therein are woven as warp or weft yarns of the fabric, so that the filament yarns surrounding the plant seeds are not easily destroyed when the soil base material is filled, and the plant seeds are wrapped. Germinate evenly on the front. In addition, the weaving machine can be easily mass-produced, and only an appropriate amount of plant seeds and paper can be used to reduce manufacturing costs, and biodegradation can be prevented by microorganisms within a predetermined period after use, thereby preventing environmental pollution.
