DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope for wrapping a root of a plant and a sheet material mainly used for wrapping the root of a tree when transplanting the tree.

[0002]

2. Description of the Related Art Conventionally, for example, when transplanting greening trees from a growing place to a desired vegetation place, the roots with the excavated soil are wrapped around a sheet material such as a straw, and the outer periphery thereof is made of a straw rope. Or tied with a rope made of polypropylene, and embedded in the desired vegetation area with the roots wrapped.

[0003]

The above-mentioned conventional planting trees, which are transplanted as described above, are often left for about 1 to 3 months after being excavated from a growing place. In such a case, When the sheet material wrapped around the root was tied with a straw rope, the rope rotted, and when transplanting, there was a problem that the sheet material opened and the soil around the root collapsed and fell.

[0004] In addition, when the roots of greening trees or the like dug up from a growing place are wrapped with a sheet material together with soil and the outer periphery thereof is tied with a polypropylene rope, the polypropylene rope has been corroded for many years. There is also a problem that they are left in the ground without being able to cause environmental pollution and inhibit root development.

[0005] On the other hand, since straw, which is a raw material of conventional straw mats and ropes, is in short supply due to a policy of reduction in quantity and the like, prices are rising.
In place of this straw, bamboo grass and ropes made from fibers of jute or palm imported from Southeast Asia are widely available, but in these products, fibers of jute or palm are contained in about 3-5%.
% Of oil content, and this large amount of oil content remains in the ground.

[0006] In addition, straw mats and ropes made of fiber such as jute or palm require a great deal of skill in the production thereof, and a considerable amount of skill is required in packing tree seeds to be transplanted using them. There was also the problem of saying.

[0007] The present invention has been proposed in view of the above-mentioned problems, and can be transplanted as it is without decay even if it is left for about 1 to 3 months after being excavated from a growing place. It is an object of the present invention to provide a plant root winding material which can be prepared easily and inexpensively, and a method for producing the same.

[0008]

Means for Solving the Problems In order to achieve the above object, a method for producing a plant root wrapping material of the present invention, particularly a rope-shaped root wrapping material, comprises a biodegradable plastic fiber spun into filaments. Rayon fiber spun into filament

The rope material is twisted in a rope shape.

[0009] Next, a method for producing a sheet-shaped plant root-wound material is as follows: biodegradable plastic is spun into filaments, formed into sized fibers, and rayon fibers or / and spun into filaments. And the regenerated fiber is formed into a sized fiber, and both the sized fibers are formed into a wrapped shape to be consolidated.

[0010] Further, among the root-wound materials of the plant according to the present invention, the rope-shaped material is formed by twisting biodegradable plastic fiber and rayon fiber and / or regenerated fiber to form a rope. is there.

Further, the sheet-shaped material of the plant root wrapping material according to the present invention is obtained by consolidating biodegradable plastic fiber and rayon fiber and / or regenerated fiber into a sheet by consolidation means. It is.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION In order to achieve the above object, the present invention provides a plant-like root-wrapping material for a plant and a method for producing the same.
First, a molten biodegradable plastic is spun into a filament. Next, rayon fibers and / or regenerated fibers are spun into filaments. Then, the filament of the biodegradable plastic fiber and the filament of the rayon fiber and / or the regenerated fiber are twisted to form a rope material.

Thereafter, when the rope material is twisted into a rope shape, a rope-shaped root material is formed.

Further, in the sheet-shaped plant root winding material and the method for producing the same, the biodegradable plastic fiber and the rayon fiber and / or the regenerated fiber spun into filaments are used as sized fibers such as long fibers and short fibers. It is formed in a shape. Next, a biodegradable plastic fiber formed into a sized fiber
Spread Wei and rayon fibers and / or regenerated fiber lap (cone) shape, so neck wrapping material sheet of the plant is formed when consolidated with heat bonding or polyvinyl alcohol (PVA) or the like of the sizing agent of this is there.

Here, the setting of the biodegradation time of the plant root wrapping material formed as described above is determined by, for example, the ratio of the biodegradable plastic fiber . That is,
In the case of rope-shaped root-wound materials, biodegradable plastic fibers
Biodegradation time increasing the number of filaments of Wei is shortened, rayon fibers and / or regenerated fiber biodegradation time increasing the number of filaments on the contrary it is possible to lengthen.

[0016] The biodegradation time of the sheet-like plant root-wrapping material can be similarly set to a desired one.

[0017]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a root winding material for a plant and a method for producing the same according to the present invention. <Example 1> Fig. 1 is a perspective view of a rope-shaped root wrapping material, and reference numeral 1 in the figure generally indicates the rope-shaped root wrapping material.

As shown in FIG. 2, the rope-shaped root-wound material 1 is formed by spinning a dissolved biodegradable plastic 2 into continuous filaments 3 and dissolving a rayon 4
Into a continuous filament 5 and both filaments 3
Twist 5 to form the rope material 6 of FIG. Next, when a plurality of rope materials 6 shown in FIG. 3 are twisted together, a single rope 7 shown in FIG. 4 is formed, and this is wound up into the rope-shaped root material 1 shown in FIG.

Example 2 This example illustrates a sheet-shaped root material.
The melted biodegradable plastic 2 in Example 1 is spun into continuous filaments 3 (see FIG. 2), and the melted rayon 4 is spun into continuous filaments 5; Cut into sized fibers 8.9 of fibers and short fibers.

Next, as shown in FIG. 6, the cut filaments 8, 9 of the long filaments and short fibers of both filaments 3, 5 are spread in a bamboo (wrap) shape, and the fibers are heated or glued together to bond them. When consolidated, the sheet-shaped root material 10 is formed.

When covering the root of a tree to be transplanted with the rope-shaped root-wrapping material 1 and the sheet-shaped root-wrapping material 10 formed as described above, as shown in FIG. A sheet-shaped root-wrapping material 10 around the root 11 of a tree
And tie the outer periphery with a rope-shaped root-wrapping material 1. At this time, if the excavated tree is to be planted immediately, a short-lived biodegradation material of the rope-shaped root-wrapping material 1 and the sheet-shaped root-wrapping material 10 is selected and used, and the excavated tree is planted. If there is a period before the biodegradation, the one with the long biodegradation time corresponding to the period is selected.

By the way, the setting of the biodegradation time of the root-wound material of a plant is determined by, for example, the ratio of biodegradable plastic fibers . That is, in the case of the rope-shaped root-wound material 1, when the number of the filaments 3 of the biodegradable plastic fiber is increased, the biodegradation time is shortened. Conversely, when the number of the filaments 5 of the rayon fiber is increased, The biodegradation time can be extended.

Further, if the ratio of the same biodegradable plastic fibers also neck wrapping material sheet of the plant is large biodegradation time is shortened, contrary to biodegradation time when the ratio increases rayon fibers It will be longer. Thus, when a plant wound using the sheet-shaped root-wrapping material 10 and the rope-shaped root-wrapping material 1 is directly planted at the transplanting site,
At the set biodegradation time, the root winding materials 1 and 10 are decomposed.

In each of the above embodiments, the combination of biodegradable plastic fiber and rayon fiber has been described. However, recycled fiber such as swoof is used instead of rayon, or regenerated fiber is blended with rayon fiber. Of course you can.

[0025]

As described above, according to the plant root wrapping material and the method for producing the same according to the present invention, in the case of a rope-shaped root wrapping material, the number of filaments of biodegradable plastic fibers is reduced. When the number is increased, the biodegradation time is shortened. Conversely, when the number of filaments of rayon fiber and / or regenerated fiber is increased, the biodegradation time can be lengthened. The desired biodegradation time can be set depending on the ratio of the conductive plastic.

[0026] Therefore, if the material is left for about 1 to 3 months after being excavated from the growing place, by using a material having a relatively long biodegradation time, the sheet material wrapped around the root is made of straw. It has the advantage of eliminating the problem that the rope rots with a rope tied or that the sheet material opens when transplanting and the soil around the root collapses.

Conversely, by using a material which is dug up from the place of growth and transplanted in a short time and which has a short biodegradation time, it can be biodegraded at an early stage. There is also an advantage that the rope does not corrode for many years and remains in the ground, thereby eliminating the problem of causing environmental pollution and inhibiting root development.

Further, according to the plant root-wound material and the method for producing the same according to the present invention, it can be produced by using a commonly-used spinning method, so that the thickness of the filament or fiber can be reduced. Can be set arbitrarily, and it is possible to produce the root-wound material of a plant with sufficient flexibility while having flexibility, so that it can be easily handled without skill and can be used for transplanting trees, etc. There is also an advantage that work costs and time can be significantly reduced.

In addition, since the root material of the plant according to the present invention is completely decomposed at a predetermined time, a straw or a rope manufactured using fiber such as jute or palm imported from Southeast Asia is used. As in the case, there is an advantage that the problem that a large amount of oil contained in fibers such as jute or palm remains in the ground can be solved.
