Description

Coating fabric for light quantity control and its manufacturing method

The present invention relates to a coating fabric for adjusting the amount of light and a method of manufacturing the same, wherein a color yarn with a UV enhancer and a color agent and a transparent yarn without a color material are arranged differently according to a required use and use conditions to weave the fabric, and a UV enhancer The present invention relates to a fabric for controlling light quantity and a method of manufacturing the same, which can provide a comfortable growth and fruiting environment by controlling the light transmittance and blocking the moisture by coating the mixed mixture on the surface of the woven fabric.

Due to the abnormal climate caused by environmental pollution all over the world, desertification is progressing rapidly. As a result, the area of arable land is rapidly decreasing, so that the cover material which can be used as a farmland that can be used for arable desert or dry barren land can be used. The research is being actively conducted.

On the contrary, in the application No. 10-2013-0068925 filed by the applicant for reinforcement for vinyl and its manufacturing method, a yarn is prepared by mixing a UV reinforcing agent with HDPE, and increasing the Denier value of the produced yarn to increase the thickness of the yarn. By increasing the number of wefts and warps per inch compared to other fabrics of the same weight, the light transmittance and strength can be improved depending on the purpose and purpose of use, such as coverings for agricultural vinyl houses, barns, sports domes, warehouses and all long-term facilities. Reinforced fabric for vinyl replacement is published.

However, the existing invention described above may inhibit the comfort of crop growth and fruiting environment due to excessive light intensity caused by improved light transmittance and increased bet temperature when used in an excessive light amount region such as Africa or South America, There is a problem in that waterproofing is impaired by passing not only light but also moisture. In addition, similar products, such as "sunshade fabric" and the like, because there is no coating film does not prevent the passage of air and moisture at all, it is difficult to control the internal environment.

In order to solve the above problems, the present invention is possible to finely control the light transmittance by weaving the fabric by differently disposing the color yarn with the UV enhancer and color agent and the transparent yarn without the color agent depending on the required use and use conditions.

Hereinafter, with reference to the accompanying flowchart and drawings will be described in more detail.

The present invention relates to a fabric for controlling the quantity of light that can be used for a variety of facilities in the extreme region and a method for manufacturing the same, HDPE (HDPE) and UV for mixing a UV enhancer to delay the damage of the fabric by ultraviolet light Reinforcing agent mixing step (S1); A color agent adding step (S2) of adding a color agent (Color Masterbatch) to display different colors according to the required use of the fabric and the use conditions; A first film manufacturing step (S3) for producing a mixed HDPE, UV enhancer and colorant in the form of a film; A first film making step (S4) of cutting the manufactured first film and processing it into a yarn shape; A yarn drawing (heating) -cooling step (S5) for drawing (heating) and cooling the yarn produced through the first film making step; A second film weaving step (S6) of putting the stretched (heated) and cooled threads into a loom and weaving it into the form of a fabric; A second film coating step S7 of applying a mixture of Low Density Polyethylene (LDPE) or Linear Low Density Polyethylene (LDLPE) and UV enhancer to both surfaces of the woven second film; The coating fabric S8 for light quantity adjustment is completed.

More specifically,

Mixing step of HDPE and UV enhancer (S1) is a step of mixing by adding a UV enhancer to a 100% Virgin HDPE (High Density Polyethylene) in a weight ratio of 80 ~ 99: 1 ~ 20, the UV enhancer is a Hindered Amine Light Stabilizer ), UV Absorber and Anti-Oxidant are mixed in the mixing ratio of 50 ~ 80: 0 ~ 30: 0 ~ 20: 0 ~ 10 in weight ratio, which can delay the damage of fabric by UV rays. have.

Colorant addition step (S2) is a step of adding a colorant to the mixture of HDPE and UV intensifiers to add a black color to block the transmission of light or to reflect the light by adding a silver color, the two mentioned above Various colorants other than colors can be mixed with LDPE or LLDPE at a ratio of 80 to 100: 0 to 20 to produce fabrics suitable for the intended use and use conditions. In the first film manufacturing step (S3), HDPE, UV enhancer, and colorant are mixed and then put into an extruding machine, and the injected mixture is liquefied by the high temperature of the dispenser, which is 0.002 ~ 5mm for the necessary use and conditions of use. Injecting the film into a thick film.

First film making step (S4) is 0.1mm ~ 1cm to pass the first film injected through the first film manufacturing step (S3) over a roller equipped with 100 ~ 3,000 knives to suit the required use and conditions It is a step that can be molded into the shape of the yarn by cutting the width of.

The first film stretching (heating) -cooling step (S5) is a first film manufacturing step (S4) to prevent the strength and durability of the yarn to which the colorant is added to control the transmittance of light is reduced compared to the yarn that is not It is a step in which the strength and durability of the yarn can be improved beyond the reference strength by stretching (heating) and cooling the yarn formed through the three to six times, respectively.

The second film weaving step (S6) is the fabric using the first film stretching (heating) -cooling step (S5) using the strength and durability improved yarn as weft and warp of the weaving loom In the step of weaving, the weft and warp in this step do not add the color yarn 10 and the color additives and other additives generally mixed in the manufacturing process to prevent the transmission of light by adding a color agent. Transparent chambers 20 are used, respectively. In addition, in this step, unlike the general weaving method that uses water when weaving, by excluding water, the moisture remaining in the weaving tissue is affected by solar heat, thereby preventing the weaving tissue from contracting or changing the flatness of the fabric. When weaving, as shown in FIG. 2, the color chamber 10 to which the colorant is added and the transparent chamber 20 to which the colorant and other additives are not added are woven differently, so that the light transmittance is adjusted to suit the required use and use conditions. It can be adjusted from 0 to 100%.

In the second film coating step S7, LDPE or LLDPE and UV intensifier are added at a weight ratio of 80 to 99: 1 to 20 to prepare a mixture, and the prepared mixture is added to a wide coating machine to both surfaces of the woven second film. It is a step of forming the transparent coating layer 30 to 15 to 70% of the total weight by applying a mixture to the fabric, and UV reinforcement is contained in the coating surface as well as the yarn, which is the basic structure of the woven fabric through the step Can effectively delay damage.
