Manufacturing method of heat mat mat for crops and heat mat fabric made therefrom {Manufacturing method of heat mat mats for crops and Heat mat fabrics made from them}

       The present invention relates to a method for manufacturing a heat-insulating mat compressed yarn for grass and crops and a heat-insulating mat fabric produced thereby, more specifically, HDPE (polyethylene having excellent coating liquid and light-shielding property capable of significantly lowering temperature on grass or various crops) ), And then extract the compressed yarn with the mixed solution, and then form the heat-resistant mat fabric useful for grass and various crops as these compressed yarns. By reducing the internal temperature as a whole, smoothly lowering the grass temperature due to high temperature, or by appropriately lowering the temperature inside the house, greatly increases the viability of the crop, and also provides a high effect of sunlight permeability and sunshade to the grass and various crops. Preparation method of heat-insulating mat for crops And it relates to a heat-resistant mat fabric produced therefrom.

Generally, water, sunlight, soil, etc. are important elements for growing plants or crops, such as crops in a greenhouse or grass in a golf course, and include secondary elements of temperature, air, and nutrients (manure). It is effective for growth. Plants planted in soil (soil) and the like grow every day with adequate supply of temperature, air, and nutrients based on water and sunlight. Various factors necessary for plant growth are the most stable as plants are supplied only in the amount needed. However, a variety of problems occur in the growth process of plants due to changes in the surrounding environment, such as climate change, such as global warming, which causes the amount of sunlight to rise too high, or the moisture in the soil is significantly reduced due to high temperature and high heat, In addition, it is also a trend that plants that are planted in soil are frequently exposed to high temperature and high temperature and that the surface surface is constantly exposed to sunlight. We have researched and developed various methods to solve this problem and applied it to actual sites, but it is still insufficient.

As an example, the Korean Utility Model Publication No. 1996-0002202 states, "The blue polyethylene film yarn (1) was used as the weave yarn (3) of the polyethylene monomer yarn to form a cover of the cross-section tissue (4). In, the black polyethylene film yarns 5 on the cross-section tissue 4 are formed into a double-stereostructure 6 over the weave monofilament 3, so that the weave monofilament 3 is not visible on the surface 7 It proposes a shading cover of the ginseng cultivation field, characterized by Ham.

The prior literature is to construct a double three-dimensional structure by double-weaving black polyethene film yarn on the surface of the cross-section structure of the light-shielding cover made of blue polyethene film yarns interwoven with cross-section tissue as a polyethene mono yarn. , By constructing the cover so that no mono thread intertwined is visible on the outer surface, the surface of the cover obtains the effect of flowing rainwater well and prevents a large amount of rainwater from gathering at the location of the ginseng plant, so that it can maintain the proper moisture for ginseng cultivation. It is explained that the covering monos of the cover can be used for a long period of time without bursting because the directs of the coverings are not directly exposed to sunlight. Also, the blue polyethene film inside helps to grow the ginseng by receiving the transparent sunlight from the ginseng. Doing.

However, the preceding literature is a special design for use only in the ginseng cultivation field. As the sunlight and wind enter and exit the inside and outside of the net directly covering plants such as crops of the greenhouse or golf course, temperature control and moisture due to ventilation It is difficult to effectively provide the effect of the sunshade that can control the oversupply of sunlight and the oversupply of removing sunlight, resulting in a problem that healthy grass and fresh crops (plants) cannot be obtained.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a method of manufacturing a compressed yarn for weaving a heat shield mat that lowers a temperature by covering a lawn and a house crop and a heat shield mat fabric woven from the compressed yarn, the first step (S10), the second step (S20), and the The main configuration is 3 steps (S30).

The first step (S10) according to the present invention forms a coating solution 10 in a molten state to exert a function of temperature control on grass and crops while blocking ultraviolet rays from the outside. The first step (S10) is a configuration for forming a coating liquid 10, such a coating liquid 10 while blocking the ultraviolet rays generated from the outside, the heat-insulating mat fabric paper 50 formed through a compression yarn 40 to be described later When it covers the grass or house crop complex, it lowers the high temperature to reduce the temperature generated in the crop within the grass or house.

At this time, the coating solution 10 of the first step (S10) is sodium (Na) 2 ~ 3wt%, magnesium (Mg) 2 ~ 3wt%, aluminum (Al) 8 ~ 15wt%, silicon (Si) 65 ~ 80wt %, Phosphorus (P) 2 to 4 wt%, potassium (K) 3 to 5 wt%, calcium (Ca) 2 to 3 wt%, and iron (Fe) 1 to 2 wt% are suitably mixed with each other. The mixed coating solution 10 may be formed by mixing a separate colorant and a UV agent in an appropriate amount together. In other words, when forming the compressed yarn 40 to be described later, it is considered to be suitable and suitable to form through a composition liquid such as titanium (Ti) as a function of setting or adjusting the overall color. The composition of the coating solution 10 is a mixture of sodium (Na), magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P), potassium (K), calcium (Ca), and iron (Fe). To complete. And in the case of a UV agent (ultraviolet) that can be mixed together separately, it plays a role of blocking the ultraviolet rays to lower the temperature. That is, in the case of ultraviolet rays contained in a large amount of sunlight, it is also called actinic radiation because of its strong chemical action and sterilization action, but if there is no ozone layer in the sky or thin, damage to plants occurs. ) To reduce this damage and protect plants. In addition, the loess helps to obtain healthy grass and crops because the humidity and temperature are smooth and the virus and bacteria can be prevented and a high rate of far-infrared radiation is possible. However, since the yellow soil is not compatible with the compressed yarn 40 and hard to harden, it is suitable to use a small amount, but since it helps to increase the strength of the compressed yarn 40, it seems that it is desirable to include an appropriate amount.

In addition, the mixed solution material 20 of the second step (S20) is characterized in that 40 to 45 wt% of the coating solution 10 and 55 to 60 wt% of HDPE are mixed with each other.

In addition, in the second step (S20) according to the present invention, the coating solution 10 of the first step (S10) and HDPE (High Density Polyethylene) to exhibit a light-shielding function are mixed with each other to form a mixed solution material 20. Next, extruded at a constant pressure through a master batch or the like to form pellets 30 of uniform size. After mixing the HDPE in the form of powder with the coating liquid 10 of the first step (S10) by melting with appropriate heat to form the mixed solution material 20, the mixed solution material 20 is master batch (master batch) It is compressed through a back to form a pellet 30 of a certain size. This HDPE is a polyethylene with high crystallinity and high density, which is excellent in heat resistance and cold resistance among mechanical properties, and has low transparency, and is a synthetic resin used for extrusion molding products such as various containers, insulating materials, wires, hoses, pipes, and ropes. The silicon contained with HDPE, which has excellent heat and cold resistance, helps maintain the temperature even in strong sunlight, and is resistant to moisture, so that it can control the temperature on grass and crops (plants). It is suitable to form in the size of 200 ~ 1000mesh.

At this time, the mixed solution material 20 of the second step (S20) is characterized in that the coating solution 10 and 40 to 45wt%, HDPE 55 to 60wt% of the mixture. It is as described above that the mixed solution material 20 in which the coating liquid 10 and the HDPE are mixed with each other is formed of the pellet 30 and the pellet 30 is formed in a uniform shape.

In addition, the third step (S30) according to the present invention is provided with a compressed yarn 40 that is formed by melting the pellets 30 of the second step (S20) by heat. Thus, after forming the mixed solution material 20 in which the coating solution 10 and HDPE are mixed with each other in the form of pellets 30, the pellets 30 of uniform shape and size are extruded in a molten state at a constant temperature and compressed yarn ( 40).

The coating solution 10 formed using the above-described manufacturing method and HDPE (High Density Polyethylene) are mixed with each other to form a mixed solution material 20, and then extruded through a master batch or the like to form a pellet 30 of uniform size. And, the pellets 30 are melted by heat and provided with compressed yarns 40 that are formed, and the compressed yarns 40 of the inclined portions 51 and the weft portions 52 that cross each other at regular intervals. Characterized in that the heat-shielding mat fabric 50 is formed through weaving.

When the heat-shielding mat fabric 50 woven with the compressed yarn 40 is used on the city grass and crops (plants), the effect and effect of reducing the temperature of the grass and crops on average is 3 to 5 ° C. have.

On the other hand, the compressed yarn 40 is formed of a mono yarn 41 or a film yarn 42, the inclined portion 51 and the weft portion 52 of the heat-insulating mat fabric 50 are mono yarn 41 or film It is characterized in that either one of the yarns 42 is formed alternatively or the mono yarns 41 and the film yarns 42 are formed in parallel with each other. Compressed yarn 40 forming the heat-insulating mat fabric 50 is formed in the form of an orthogonal (inclined portion and weft portion) with each other to form the fabric paper 50. At this time, the inclined portion and the weft portion 51, 52 ) Is based on weaving by arranging at regular intervals so as to cross weave with each other while maintaining a width of about 0.1 to 0.2 cm. By changing the range of width length to some extent, the crossing gap is adjusted to suit the intended use and usage environment. It will be necessary to use it with increasing or decreasing. In addition, in the case of the heat-insulating mat fabric 50, it can be woven by appropriately adjusting so as to bring both shade and permeability, but rather than setting and weaving the weaving method of the inclined portion 51 and the weft portion 52, rather than weaving the crop. It is desirable to focus on the environment of use and weave to be excellent in shading and permeability.

In addition, the compressed yarn 40 is formed of a mono yarn 41 or a film yarn 42. At this time, the mono yarn 41 is formed using a thickness of about 50 to 300 denier, but is about 150 to 200 denier. Is preferred, and in the case of fabrics that require more permeability to sunlight and wind, weave it to a suitable thickness. In addition, the film yarn 42 has various thicknesses and colors, and is used for various types of fabric fabrics, meshes, and strings, and is also used for decoration of high-quality fabrics due to its characteristics having various colors and high-gloss surfaces. It is possible to utilize. The width of the film yarns 42 is generally in the range of about 0.5 mm to 1.5 mm, but if the width is too narrow, it is not desirable to exhibit sufficient frictional properties as desired, and if the width is too wide, knitting is difficult. The texture is too rough, making use uncomfortable. Since these film yarns 42 have a flat cross-sectional shape, when they are bent at an angled edge or when a thin side surface protrudes, they provide strong friction in use. The thickness of the film yarn 42 is preferably configured to be used in approximately 400 to 1000 denier, and is composed of various types such as thickness, color, surface, etc., so the most suitable thickness according to the configuration of the selected film yarn 42. Apply and use. These film yarns 42 are composed of a wider width than the mono yarns 41, and thus, when weaving with a fabric, can reduce the excessive amount of sunlight, and thus have an excellent advantage in improving sun shading. Therefore, when forming the heat-insulating mat fabric 50, weaving in various forms by using the advantages of the mono yarn 41 having excellent advantages in temperature control and moisture removal due to ventilation and the film yarn 42 capable of enhancing shading properties can do. This, the inclined portion and the weft portion (51, 52) can be formed only by the mono yarn 41, the light-weft portion (51) (52) can be formed only by the film yarn 42, the mono yarn ( 41) and the film yarn 42 may be used in parallel to form the heat-insulating mat fabric 50. In addition, the arrangement positions of the mono yarns 41 and the film yarns 42 can also be variously configured, thereby improving the usability. That is, the monofilament yarn 41 and the monofilament 41 are composed of the light and weft portions 21 and 22, the monofilament 41 and the film yarn 42 are constituted, and the film yarn 42 and the film yarn 42 are formed. It can be formed in a configuration, in addition to the inclined portion 21 or the weft portion 22, the mono yarn 41 and the film yarn 42 can also be formed in a variety of arrangements.

According to the present invention, after extracting the compressed yarn with a mixed solution of HDPE (polyethylene) excellently mixed with a coating solution capable of significantly lowering the temperature on grass or various crops, and then extracting compressed yarn as such compressed yarn, As it forms a useful heat-resistant mat fabric, it reduces the temperature inside the grass or the crop complex for house while reducing the temperature of the grass or the temperature inside the house. It greatly increases the viability of crops, and provides an effect that can provide a high effect of sunlight permeability and sunshade on grass and various crops.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the claims of the present invention.
