Description

[0001] The present invention relates to vegetation-based biodegradable fibers containing biodegradable fibers and a vegetation-based biodegradable fiber-

The present invention relates to a vegetation substrate for a greening method comprising a biodegradable fiber and a greening method using the vegetation substrate. More particularly, the present invention relates to an aliphatic polyester biodegradable fiber, an aliphatic / aromatic copolyester biodegradable fiber, A vegetation net, a vegetation mat and the like, and a greening method using the same.

The vegetation construction method or the greening method is collectively referred to as preserving the environment, scenery and land by the vegetation composition, the nature of the rust. In particular, the slope protection method in the greening method is a method for covering the vegetation on slope slope and preventing erosion by rainfall, and is mainly applied to a weathered layer or a soil layer which is highly weathered. If slope slope is clay, weathered, or soft rock, slope is more than 1: 1.2, or slope slope is sandy soil and slope is more than 1: 1.5, it is difficult to maintain slope stability by general vegetation method only. Other slope protection methods should be considered.

In general, slope protection methods include seed spray, mat, net, and lime soil. Among them, the seed spray method is a method in which a mixture of a fertilizer, a coating curing agent, an anti-erosion stabilizer, a coloring agent, purified water, etc. is sprayed on a ground to be recorded with a high-pressure pump to record seeds or plant seeds. The net method is a method of making synthetic fibers consisting of nylon, polypropylene, polyethylene, PVC, etc., made of natural fibers consisting mainly of coir (coir), jute, rice straw, Net) and then attached to the ground, and seed composite such as grass seed seed spray or seed spray is sprayed to record. The mat method is a method of making a web or non-woven mat from natural fiber alone, synthetic fiber alone, or mixed fibers of natural fibers and synthetic fibers, such as coir, jute and rice straw, It is a method of applying a seed composite material such as a grass seed or a seed spray by applying a net, a paper layer, a seed layer and the like used in the net method to a green or a composite layer or a single layer to be recorded. In the case of making the mat while inserting the seed into the mat, it is possible to reduce the step of spraying the seed after netting. The Roksan soil method is a method to produce artificial soil (rye soil) containing soil and various complex organic materials (sawdust, paper sludge, natural fiber, fertilizer, compost, manure etc.), various adhesives and microorganisms, It is a wet method to record by attaching. In order to increase the adhesion to steep slopes and rocks, wire netting, polymer netting and so on are installed first, and then rye soil is installed.

When these existing methods are used, the following problems are continuously being raised. The seed spraying method has a problem in that it is impossible to smooth vegetation because of the loss of soil nutrients and seeds due to rainfall or wind on a sloping slope, or a phenomenon of skewness. In the net method and the matting method, since the biodegradation of a net made of natural fibers such as coir, jute, rice straw and the like has progressed too quickly after the recording, the protective function of the net , Seed loss, soil erosion, etc.) are often lost. In addition, nets composed of synthetic fibers such as nylon, polypropylene, polyethylene, and PVC are not biodegradable and therefore not environmentally friendly, and the net structure of non-biodegradable materials interferes with vegetation (plant growth). In the case of artificial soil (when artificial soil is used), the Rokto soil method is applied to the existing soil due to lack of adsorption capacity of artificial soil at the time of drying (sliding) In case of severe disturbance and cracking phenomenon of artificial soil layer and deficiency of moisturizing power, poor growth of greenery plants and excessive rainfall in case of heavy rainfall, the soil can not overcome its own weight and collapse, There is a problem that occurs.

Therefore, there is a continuing need for a new greening method using an artificial soil composition that can be used for greening in a cut or fill area requiring an artificial vegetation condition, and a net and mat of suitable kinds and sizes.

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems, and it is an object of the present invention to provide a method for improving the seed germination rate, seed coverage rate, reduced seeding rate, And to provide a vegetation base having a soil loss rate and having little cracks and separation and capable of forming a uniform vegetation.

As shown in Table 2, when a biodegradable fibrous nonwoven fabric or a seed-integrated biodegradable fibrous nonwoven fabric-type vegetation mat is used, a higher covering ratio and a germination rate of dapper It looked. In addition, in a vegetable mat in the form of a biodegradable fiber nonwoven fabric, in particular a vegetation mat in the form of a seed-integrated biodegradable fibrous nonwoven fabric, a nonwoven vegetable mat made of mixed fibers obtained by mixing the natural fiber jute and the biodegradable fiber according to the present invention, And the germination rate was higher than that of other species. It is considered that this is because the relatively hard jute is mixed with the PLA fiber, the nonwoven fabric voids on the seed surface increase, and the jute is faster in water absorption rate and biodegradation than PLA, and the mixed fiber, which is a mixture of the natural fiber and the biodegradable fiber of the present invention, When it is used as a material for a net or a vegetative mat, the manufacturing cost is reduced, which is advantageous in terms of economy. In addition, although not shown in Table 2, it is possible to uniformly arrange the seeds when the greenery method (Test Examples 3 to 7) was carried out using the vegetation substrate of the present invention, and the seeds could be moved and lost due to external forces such as rainfall (More specifically, between the mat and the ground surface) of the rainfall, thereby reducing the loss of the soil. In addition, biodegradable fibers are biodegraded over time to act as a compost, thereby further promoting plant growth.

As shown in Table 3, in the case of Test Example 8 and Test Example 9 using a vegetative net in the form of a biodegradable fibrous nonwoven fabric or a seed-integrated biodegradable fibrous nonwoven fabric and a vegetative net in the form of a biodegradable film, the high coverage rate and the germination rate It looked. Especially, the highest coverage rate and germination rate were obtained when using vegetable mat of seedless biodegradable fiber nonwoven fabric. In the case of the greening method (Test Example 8 and Test Example 9) using the vegetation substrate of the present invention, it is composed of 100% environmentally friendly material and has no environmental pollution, and the biodegradable film vegetation net has a low intensity And decomposition occurred, so that the growth of the plant was not impaired. When the greenery method was carried out using the vegetation substrate of the present invention, the seeds were uniformly arranged, and the coating rate was remarkably improved by preventing movement and loss of seeds due to external forces such as rainfall. In addition, by reducing the flow velocity of the surface of the rainfall (more specifically, between the mat and the surface), the loss of soil is reduced and the nonwoven fabric under the seed layer absorbs / moisturizes the water to improve the germination rate and germination rate of the seed. In addition, biodegradable fibers are biodegraded over time to act as a compost, thereby further promoting plant growth.
