DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation substrate formed by laminating sheet-like thin cotton on a net or mat made of, for example, polyethylene fiber, coconut fiber, palm hair, jute, wood wool, or the like. It is about.

[0002]

2. Description of the Related Art In a conventional vegetation substrate, a net or mat and a sheet-like thin cotton are laminated, and the two are integrated by bonding with a water-soluble adhesive or sewing with a thread. There were the following problems.

That is, in the former case, a large amount of a water-soluble adhesive is required, and drying is troublesome, resulting in poor production efficiency. In particular, if the net or mat is made of coconut fiber or palm hair, when applying a water-soluble adhesive with a roller, the fuzzy fibers on the surface are easily broken and easily adhere to the roller surface, A uniform adhesive state may not be obtained.

In the case of the latter, not only the thread to be sewn is indispensable, but also the sewing speed is low, so that the production efficiency is poor and the thread is partially fixed (sewing). In some cases, the sheet-like thin cotton was unexpectedly peeled off from the time of transportation and during the construction after production.

In order to avoid this inconvenience, if the sewing density is increased while sacrificing the manufacturing efficiency, the smooth detachment (peeling) of the thin cotton after construction is hindered by the yarn. In other words, this kind of vegetation substrate prevents the erosion of the slope with a net or mat by laying it on the slope so that the thin cotton comes down, and also prevents the thin cotton from being dissipated by the weather. The sheet-like thin cotton absorbs rain, becomes supple and heavier, detaches from the net or mat, adheres to the ground surface to cover seeds, etc., and germinates and roots. It is desirable that the sheet-like thin cotton stably integrates with the net or mat until the completion of construction, and it is desirable that it be peeled off early after construction. Was difficult.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and is intended to provide a vegetation substrate in which sheet-like thin cotton is laminated on a net or a mat. Focusing on the entangled fibers, instead of simply laminating and laminating sheet-like thin cotton on a net or mat as in the past, using the property that thin cotton fibers entangle Without using it, or even if it is used, with a very small amount of use, the net or mat and sheet-like thin cotton can be effectively integrated so as not to be accidentally peeled off before construction, and after construction Another object of the present invention is to make it possible to quickly release sheet-like thin cotton from a net or a mat.

[0007]

Means for Solving the Problems In order to solve the above problems, the present invention takes the following technical means. That is, the vegetation substrate according to the present invention is formed by laminating a net or mat made of polyethylene fiber, coconut fiber, palm hair, jute, wood wool, and the like, and sheet-like thin cotton, and both of them are made of thin cotton fiber. It is integrated by being entangled with the fibers of the net or mat, and furthermore, the thin cotton is quickly separated from the net or mat by absorbing rainwater or the like, and is configured to adhere to the ground surface. It is characterized by having been done.

According to the above-mentioned structure, the sheet-like thin cotton is entangled with the net or mat fiber to integrate the net or mat with the sheet-like thin cotton. Can be integrated without using a water-soluble adhesive, even if a water-soluble adhesive is used, the amount used is very small, and a large amount of water-soluble adhesive is not required,
In addition to being economical, the labor for drying is reduced, and efficient production can be achieved.

[0009] In addition, when the net or mat and the sheet-like thin cotton are laminated and pressed between rollers, the thin cotton fiber is entangled with the net or mat fiber. The fixing is not partial as in the case of wearing, and the thin cotton sheet is integrated with the entire surface of the net or mat. Therefore, it does not peel off unexpectedly before construction, but because it is integrated by entanglement of fibers, after construction, sheet-like thin cotton absorbs rainwater etc., becomes supple and heavy, and the net Or quickly detached from the mat, will be in close contact with the ground surface to cover the seeds, etc., seed germination, rooting is reliable,
Good survival.

Before passing the laminated net or mat and the sheet-like thin cotton between the rollers, air is blown from the thin cotton side or air is sucked from the net or mat side to remove the thin cotton into the net or mat. Raising on the mat side is preferable from the viewpoint of ensuring that the fibers are entangled by roller pressure.
In addition, the net or mat made of palm fiber, palm hair, jute, wood wool, etc. has a fluffy surface, so that the thin cotton fiber is easily entangled, and the net or mat and the sheet-like thin cotton are well integrated. Is made.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a vegetation substrate A according to the present invention and a method for producing the same. In the figure, 1A is a fluffy net having a surface made of coconut fiber (may be palm hair, jute, wood wool, etc.). On the lower surface of the net 1A, a sheet, such as a soup, which is dispersed early by moisture is used. And the fibers a of the thin cotton 2 are connected to the net 1A.
Thus, the net 1A and the sheet-like thin cotton 2 are integrated without using a water-soluble adhesive. A plant growth substrate 4 such as a plant seed 3 and a fertilizer is adhered to the surface of the sheet-like thin cotton 2 using a water-soluble sizing agent such as polyvinyl alcohol. Further, when the vegetation substrate of the present invention is simply used as a protective material for covering the ground surface, or when germination of buried seeds or flying seeds of local vegetation is expected, seeds and the like do not adhere to the thin cotton 2.

The method of manufacturing the vegetation substrate A will be described. As shown in FIGS. 2 and 3, a pair of upper and lower rollers 5 are stacked in a state where the net 1A and the sheet-like thin cotton 2 are laminated.
3 and 4, the fibers a of the thin cotton 2 are applied to the net 1A, that is, the yarns knitting the net 1A, and the fibers which are fluffed on the surface of the yarns, as shown in FIGS. b, the net 1A and the sheet-like thin cotton 2 are integrated, and then, if necessary, a plant seed 3 and a plant growth substrate 4 such as a fertilizer are added to the surface of the thin cotton 2 with a water-soluble glue. The vegetation substrate A is manufactured through a step of bonding with an agent.

The adhesion of the plant seeds 3 and the plant growth substrate 4 to the surface of the thin cotton 2 is performed by, for example, spraying the plant seeds 3 and the plant growth substrate 4 coated with a water-soluble glue on the surface of the thin cotton 2. , After humidification,
After applying pressure or spraying the plant seeds 3 or the plant growth substrate 4 on the surface of the thin cotton 2, a water-soluble glue (a so-called foam adhesive containing a myriad of air bubbles is preferable) is applied or thinned. Cotton 2
Any known means such as applying a water-soluble glue (foam adhesive) to the surface and then spraying the plant seeds 3 or the plant growth substrate 4 can be employed.

FIGS. 5 and 6 show another embodiment of the present invention, which is characterized in that the thin cotton 2 is raised on the side of the net 1A by airflow in order to promote the entanglement of the fibers a. That is, in the embodiment of FIG. 5, a nozzle 6A is provided above the vicinity of the rollers 5a and 5b, and immediately before the laminated net 1A and the sheet-like thin cotton 2 are passed between the rollers 5a and 5b, the thin cotton 2A is formed. By blowing air 7 from the side, the thin cotton 2 is raised to the net 1A side, and the raised fibers a are applied to the net 1A by the rollers 5a, 5b while the fibers a have entered the mesh or fiber gap. I try to press.

In the embodiment shown in FIG. 6, the rollers 5a, 5b
The vacuum device 6B is provided below the vicinity of the roller, and the air 7 is sucked from the net 1A side just before the laminated net 1A and the sheet-like thin cotton 2 are passed between the rollers 5a and 5b, so that the thin cotton 2 is removed. Brushed fiber a raised on the side of the net 1A
The rollers 1A and 2 are pressurized by the rollers 5a and 5b in a state in which the fibers 1 enter the mesh and the fiber gap of the net 1A.

In each of the above embodiments, the vegetation substrate A is formed by laminating and integrating the net 1A and the sheet-like thin cotton 2.
But instead of the net 1A, coconut fiber,
A fluffy mat with a surface made of palm hair, jute or the like may be used. FIG. 7 shows an example of such a case, in which a mat 1B produced by locally bonding coconut fibers with a non-hydrophilic adhesive such as latex as a binder, and a sheet-like thin cotton 2 are laminated. 2 is entangled with the mat 1B so that the mat 1B and the sheet-like thin cotton 2
Are integrated to form a vegetation substrate A. Other configurations and manufacturing methods are the same as those of the above-described embodiment.

According to the above-described manufacturing method, the fiber a of the sheet-like thin cotton 2 is entangled with the net 1A or the mat 1B having a fluffy surface, so that the net 1A or the mat 1B and the sheet-like thin cotton 2 are entangled. And thus can be integrated without using a water-soluble adhesive for bonding them. Even if a water-soluble adhesive is used, the amount of water-soluble adhesive used is, for example, A very small amount such as spraying a water-soluble adhesive on the upper surface of the net 1A or the mat 1B is required, and a large amount of a water-soluble adhesive is not required. It can be manufactured.

The vegetation substrate A produced by the above-described method comprises a roller 5a, 5b in a state in which the net 1A or mat 1B having a fluffy surface and the sheet-like thin cotton 2 are laminated.
Since the fibers a of the thin cotton 2 are entangled with the net 1A or the mat 1B by being passed through and pressurized, the fixing is not partial as in the case of sewing with a thread, but is a sheet-like thin type. Since the cotton 2 is integrated with the entire surface of the net 1A or the mat 1B, the cotton 2 is not accidentally peeled off before construction.

[0019] In performing the greening slope using the above vegetation substrate A, as shown in FIG. 8 (A), slope B vegetation base A from the posture shown in FIG. 4 is inverted vertically Will be laid. Even if a gap is formed between the vegetation substrate A and the slope B due to the unevenness of the slope B, the sheet-like thin cotton 2 is
8B, the sheet-like thin cotton 2 absorbs rainwater or the like as shown in FIGS. 8 (B) and 8 (C). As it becomes heavier, it quickly separates from the net 1A or the mat 1B and comes into close contact with the ground surface so as to cover the seeds 3 and the like, so that germination and rooting of the seeds are ensured and survival is good.

[0020]

As described above, according to the present invention, a net or mat and a sheet-like thin cotton can be formed without using an adhesive or with a very small amount of use even if it is used. In addition, there is an effect that the sheet-like thin cotton can be quickly separated from the net or the mat after the construction, and the like can be effectively integrated so as not to be accidentally peeled off before the construction.
