Description

Blackout curtain

The present invention relates to a light shielding film, and more specifically, it is possible to efficiently control temperature of a plastic house because both light shielding and aeration can be performed, and it is not easily stretched even when a pulling force is applied in the longitudinal and transverse directions. It is intended to provide a light shielding film which can maintain a high temperature and prevent deterioration even after long-term exposure to sunlight.

If crops are controlled at will through agricultural production under artificial environmental composition, agricultural production can be an industrial process. This production system is called controlled or environmentally controlled agriculture. Almost all of the microorganisms have already been industrialized in the same form, but crops are self-contained organisms, which fix their own solar energy.

As such, most people use vinyl houses to achieve their intended purpose by changing the timing of production in agriculture or by using facilities for special production. In this case, the type of environmental control is largely ① ① warming and heating to keep room temperature at low temperature, ② carbon dioxide concentration control for gas environment control, ③ light control to increase limited light intensity or limit high intensity, ④ soil moisture Water supply control for proper supply of fertilizer, and ⑤ fertilization and fertilization method for rational crop nutrition.

The present invention relates to a technology for controlling the temperature in the plastic house by light control.

As a related art in the related art, Korean Utility Model Publication No. 1991-0005444 (1991.07.27. Announcement) "Shading Film" (hereinafter referred to as "prior art 1") and Korean Patent No. 10-0991727 (2010.10) .28. Registration) "Shading insulation curtain" (hereinafter referred to as "prior art 2") and Japanese Utility Model Registration No. 2529768 (registered Dec. 20, 1996) "Agricultural covering material" (hereinafter referred to as "prior art 3"). Is known.

The prior art 1 is inserted between the warp yarns (1) (1 ') of the monofilament yarn, the insertion weft (2) (3) made of poly ethylene film having a width of about 3 mm in the table, double across the back surface Knit, but insert the aluminum-deposited polyester film (4) having a width of about 12 mm to fit the gap between the adjacent strand pieces (1) (1 ') between the table and the back weft (2) (3). A technique is disclosed to block light and heat and to prevent leakage.

However, in the prior art 1, since the polyester film 4 is completely installed to prevent leakage, when the light shielding film is installed in the vinyl house, ventilation is not performed, and heat of the vinyl house is not released and is trapped. It is difficult to control and as a result, the temperature in the plastic house may be overheated.

In addition, since the polyester film 4 is entirely installed, there is a problem in that the wind cannot pass through the light shielding film and the light shielding film is peeled off from the vinyl house.

In addition, the prior art 1, when viewed on the basis of one position, the polyester film (4) is supported by one insertion weft (2) on the front side, and is supported by one insertion weft (3) on the back side Because of this, the support force of the polyester film 4 by the warp knitted fabric (1) (1 ') and the insertion weft (2) (3) is not sufficient, and the force to withstand the force applied in the inclined direction (longitudinal direction) It may be sufficient, but the force to withstand in the weft direction (lateral direction) is weak, and the gap between the warp knitting piece tissue (1) (1 ') increases as the insertion weft (2) (3) increases. It is not close to the plastic house, it is fluttered by the wind, and there is a fear of flying by the strong wind.

The prior art 2 has a structure in which a plurality of straps 10 arranged in parallel with each other, a plurality of knots 22 and a plurality of knots 24 at regular intervals in a longitudinal direction are connected, and the strap 10 A plurality of weft yarns 20 arranged at adjacent boundaries of the plurality of weft yarns, and through the knotted ring 24 of the weft yarns 20 to form a ring portion 32 and a connecting support portion 34 which is connected to the ring portion 32. It comprises a plurality of warp yarns 30 to support the strap 10 by forming a), the warp yarn 30 is at least two straps adjacent to each other a plurality of ring portions 32 provided in the longitudinal and horizontal directions By being intertwined with the knotted ring 24 of the plurality of wefts 20 arranged at the side portions of the side 10, the warp yarns 30 support the plurality of straps 10 adjacent to each other and at least three wefts ( 20) is a multi-binding structure, which is the main part of shading function Disclosed is a technology for improving product reliability as a thermal insulation screen by weaving a plurality of threads holding a light shielding strap into a special structure that is not easily released.

However, in the prior art 2, because the knot ring and the knot ring formed in the weft thread is connected to one thread, the weft yarn is easily stretched by the force applied in the longitudinal direction (longitudinal direction) of the weft yarn, and the warp yarn is also based on the position. In view of this, since the strap is supported by one warp on the front side and by one warp on the back side, the warp is easily stretched by the force applied in the longitudinal direction (transverse direction) of the warp, so that the coupling of the strap There is a problem of loosening, and consequently, product reliability.

The prior art 3 arranges a plurality of chain knitting yarns in parallel to be inclined, weaving the insert yarn to form a turn with respect to the chain portion of the chain knitting yarn, and the insertion yarn is knitted between the chain knitting yarns and at the same time the front and rear of the film-like curtain piece. The sheets formed by inserting the curtain pieces between the inserting yarns to be alternately positioned are connected to each other by a connecting part, and the connecting part is composed of a knitting structure composed of chain knitting yarns and yarns that are more flexible than the inserting yarns as multifilaments. Technology that can add foldability when it is mounted on a slide curtain without damaging the excellent coating effect and high durability of the thermal insulation curtain of the gardening house, and effectively control the temperature in the house by shading in the summer It is starting.

However, the prior art 3 adds foldability by configuring a plurality of sheets composed of chain knitting yarns, insert yarns, and film-like curtain pieces by knitting fabrics composed of yarns that are more flexible than chain knitting yarns and insertion yarns. It may help to cover the house, but it will easily stretch when the pulling force is applied in the longitudinal or transverse direction by wind, etc., and it cannot be restored after it has been increased once. There is a problem.

In addition, the prior art 3 is that the strap is supported by one inserting yarn on the surface side, and is supported by one inserting yarn on the back side when the insertion yarn is viewed on the basis of one position, so that the length of the inserting yarn (lateral direction) Insertion yarns are easily stretched due to the force applied to them, so that the coupling of the strap is loosened, resulting in a decrease in product reliability.

Republic of Korea Utility Model Publication No.1991-0005444 (Announcement dated 27.27.199) Republic of Korea Patent No. 10-0991727 (2010.10.28. Registered) "Shading insulation curtain" Japanese Utility Model Registration No. 2529768 (registered Dec. 20, 1996) "Agricultural coating material"

The x weft filament is sequentially inserted into loop 1 (R1) of y slope (Yy), y + 1 slope (Yy + 1), and y + 2 slope (Yy + 2), and then y + 2 Inverted to loop 2 of ramp (Yy + 2), loop 2 of ramp y + 2 (Yy + 2), ramp y + 1 (Yy + 1), and ramp y (Yy) It is inserted into R2) and then inverted toward the third loop R3 of the y slope Yy as one cycle, and the same type of cycle is the y slope Yy and the y + 1 slope (Yy + 1). ) And y + 2 slopes (Yy + 2) are formed repeatedly for loops 3 (R3) to 1 / r loops (Rℓ / r),
The surface weft (XAx) and the back weft (XBx) are composed of two strands of filaments so that the surface and back of the strap (S) are formed by four strands and four strands of the weft on the loop (Rr) line.
