Description

Method for preparing a slope recording net and a slope recording construction method using the net {Method of Preparing Nets for Afforestation of Slope and Afforestation Method Using the Same}

The present invention is easy to stabilize the slope of the slope, the early recording of the slope is made according to the early development of the seed, the production method of the slope greening construction net that can stabilize the soil by the formation of mycelia of soil microorganisms, by the above method It relates to a slope recording construction net manufactured or a slope recording construction method using the net.

In general, the greening method applied to the soil slope has been applied to various methods such as seed-spray, seed mat method.

The seed spraying method is a simple spraying of erosion stabilizer, Carboxyl Methyl Cellulose (CMC), fiber, compound fertilizer, colorant (M-green), mixed with seeds and water using a hose. As a method of feeding, soil nutrients were swept away or seed loss occurred during rainfall or strong winds, so that the desired erosion prevention and germination promotion could not be expected.

In addition, the seed mat method can be expected to play a role as a fibrous fertilizer due to the decay of the natural fiber itself as a coating material, and has an effect of preventing soil loss due to the mat, but it is difficult to expect a fertilizer role of the natural fiber in poor areas. And there was a disadvantage that the vegetation coverage is greatly reduced.

That is, such a conventional greening method for slopes or slopes is difficult to apply to the dry and sparse Masato area, the structure area where natural vegetation is difficult to stick. Recently, various organic materials (for example, pitmoss, bark compost, uni-fertilizer, peat, etc.) or multi-functional polymer materials have been used to overcome the limitations on the greening area, but still sliding during rainfall or strong winds. (sliding), osteoporosis, etc. are occurring.

This phenomenon is caused by the lack of bond between slope and vegetation base material, and it is possible to increase cohesion between slope and vegetation base material. Although a method of installing in the middle is attempted, the ridge network is a setting that requires a lighter and more environmentally friendly medium because it can not only destroy the ecosystem but also need to remove it later.

The present inventors endeavored to develop a method of manufacturing a net that can be used for slope greening construction while maintaining basic physical properties and stabilizing slope soil. As a result, the lyocell composite spun yarn was prepared under specific conditions, the net was manufactured using the same, and a composition for planting containing soil microorganisms was prepared and applied to the slope, and as a result, the stabilization of the slope was easy, According to the early greening of the slope is made, by confirming the stabilization of the soil by the formation of mycelia of soil microorganisms, the present invention was completed.

Accordingly, an object of the present invention is to provide a method for producing a net for slope greening construction.

The present inventors endeavored to manufacture a net that can be used for slope greening construction while maintaining basic physical properties and to develop a method for stabilizing slope soil. As a result, the lyocell composite spun yarn was prepared under specific conditions, the net was manufactured using the same, and a composition for planting containing soil microorganisms was prepared and applied to the slope, and as a result, the stabilization of the slope was easy, The early greening of the slope was performed, and it was confirmed that the soil was stabilized by the formation of mycelia of soil microorganisms.

Hereinafter, a detailed step-by-step description of the method of the present invention for producing a net for slope recording work as follows:

(a) as the sheath yarn (sheath) supply of lyocell irradiation

The "lyocell fiber" used in the present invention is a scientific name of a new material fiber given by BISFA, an organization that establishes and authorizes the fiber standard terminology in 1989. As a kind, pure pulp is dissolved in a solvent (NMMO) and is manufactured without chemical reaction in a pollution-free manner, and it is possible to maintain high polymerization degree and strength of raw materials, and most solvents for dissolving pulp in the manufacturing process are recovered in the washing process (99.8). It is known that it does not generate any pollution in the manufacturing process because it is purified and reused, and has excellent heat retention, hygroscopicity, breathability, peeling property and durability.

The lyocell irradiation used in the present invention utilizes pure pulp to provide a sliver with a fineness of 0.20-0.22 Ne through an open and picking process and a carding process, which are known in the art. After preparing several slivers in the drawing process, draw them to the D / R ratio 9.0-9.3 with the thickness of the first sliver, and prepare the lyocell irradiation in the roving process.

The method of the present invention is passed through a 1.5-2.0 number of lyocell irradiation prepared in the manner described above with a trumpet and three pairs of draft controllers as sheath yarns.

The lyocell irradiation is adjusted to 1.5-2.0 of the thickness of the feed irradiation so as to wrap around the core yarn without being cut while being formed into a composite spun yarn, the total draft ratio is preferably a D / R ratio 9.0-9.3. If the draft ratio is less than 9.0, it is difficult to manufacture a composite spun yarn of sufficient thickness. If the draft ratio is more than 9.3, excessive draft may result in problems such as trimming and non-uniform linear density.

(b) feeding the sheath yarn to wrap around the core yarn

Then, the method of the present invention is a core (core) 10-20 number of lyocell spinning yarns through the yarn guide roller to the square triangle on the front roller of the three pairs of draft controller of step (a) by the step The sheath yarn of (a) is subjected to the step of wrapping around the core yarn.

The lyocell spinning yarn used in the present invention is an open and picking process, a carding process, a drawing process, a drawing process, a roving process, which are the spinning processes known in the art. 10-20 number of lyocell spun yarns prepared through a spinning process.

When the lyocell spinning yarn is out of 10-20 number, there is a problem that sufficient tensile strength may not be given and thus, the core yarn cannot be sufficiently served.

Through this method, sheath sine lyocell irradiation is wrapped around the core sine lyocell yarn.

(c) Preparation of lyocell composite yarn

The method of the present invention can then prepare a composite yarn through a ring spinning machine at TM 2.0-3.0 and spindle speed 1000-2000 rpm by passing the core yarn and sheath yarn through a traveler.

In the present invention, it is preferable to control the TM to 2.0-3.0, and less than 2.0 TM may have a weak shape stability of the sheath yarn, so that the composite spun yarn may be nonuniform and have a weak tensile strength. There is a problem that the touch is hard.

In this way, 5-14 lyocell composite yarns can be prepared.

(d) producing a net (net)

Finally, the method of the present invention produces a net using the lyocell composite yarn of step (c).

Specifically, the net is formed in a lattice shape while intersecting the composite spun yarn of step (c) with a warp and weft, twist one of the warp or weft into two strands, and then penetrate the other by passing the other between them. To form a net.

The net is formed by weaving a warp yarn and a weft yarn formed of a lyocell composite spun yarn in a lattice shape, and an intersection portion is formed by twisting it by forming at least one of the two strands of the warp yarn and the weft yarn. Specifically, when the weft is composed of two strands and they are twisted together to form, the warp yarn is configured to penetrate the central portion of the weft twisted by the two strands.

Thus, since the warp yarns are woven through the center portion of the weft yarns, the intersection of the warp yarns and the weft yarns can be substantially completely fixed. In this way, the intersection between the warp and the weft yarn is configured to be completely fixed, so that the warp and weft yarn is more firmly fixed and the overall strength is further improved.
