Description

Insulation Fabric {INSULATION FABRIC}

The present invention relates to a heat insulating fabric, and in detail, a weft yarn made of a polyester yarn or a PET DTY yarn and a bottom layer woven in a warp yarn, and a warp yarn made of a weft yarn made of a polyester yarn or a PET DTY yarn fiber yarn and an aluminum strip yarn. It is woven orthogonally and is composed of an upper layer which is integrally woven on the upper part of the lower layer by a joint yarn made of fiber yarn, and when used as a greenhouse insulation curtain, etc., it has both heat insulation and shading properties and high durability against sunlight and moisture. It can be used for many years, the thickness is thin and the weight is light, so that the opening and closing device does not take a large load to enable the smooth opening and closing operation.

Agricultural house or greenhouse consists of several layers of vinyl to insulate the interior and exterior of the house. At night, the house is covered with a heat cover (curtain). Will be maintained.

Conventional greenhouse thermal insulation cover that is used for this purpose has been used in the form of a quilted cotton or a vinyl pad in the interior or exterior of the non-woven fabric, usually in the interior of the fabric consisting of non-woven fabric, such a conventional greenhouse Insulating cover is heavy and inconvenient to use, the manufacturing process is complicated, the productivity is low, there is a problem that does not last long life, as well as had a problem of not having adequate ventilation and light shielding.

On the other hand, in recent years, a non-woven fabric or a non-woven fabric or a heat insulating curtain that is sewn (quilted) or glued together with an aluminum screen on one side of the woven fabric has been developed and used. There was a complicated production process in which the woven fabric had to be sewn or glued with a separately manufactured aluminum screen, and the woven or nonwoven fabric and the aluminum screen were joined together by sewing or adhesive. Problems and the gap between the woven or nonwoven fabric and the aluminum screen is opened, the opening and closing operation of the insulation cover is not smooth, but also has a disadvantage of shortening the life, when bonded using an adhesive, environmental changes such as temperature and humidity Can not easily adapt to the fall and bite As a result, there is a problem that the function as a house insulating material is significantly reduced, as well as the insulating material itself becomes stiff due to the hardening of the adhesive and thus does not meet the purpose of use.

The present invention has been made in order to solve the above problems, the object of the present invention is to have a heat insulating property (heat insulation) and light-shielding properties and moisture permeability in one direction at the same time, when the weight is light, when used as a house heat insulating material, the load on the switchgear greatly The present invention provides a versatile thermal insulation fabric having a long life that can be used for many years due to its excellent durability.

In order to achieve the above object, the present invention, weft and aluminum made of a weft yarn made of a fiber yarn material including PET DTY yarn or polyester yarn and a lower layer orthogonal to the warp yarn, and a fiber yarn comprising PET DTY yarn or polyester yarn An insulated fabric consisting of an upper layer orthogonal to an inclination made of strip yarn and integrally woven on the upper surface of the lower layer by a bonding yarn made of fiber yarns, wherein the aluminum strip yarn is UV coated, and the bonding yarn is the weft of the bottom layer and the weft of the top layer. Zigzag weave between to integrally combine the lower layer and the upper layer, and the bonding yarn is woven in a zigzag form between the three rows of weft of the lower layer and the first row of weft of the upper layer, but four lines of the bonded yarn of the lower layer to improve the smoothness Continuously weaved with one row of wefts spaced apart It characterized.

According to the present invention, since the lower layer having heat insulating property and the upper layer having light blocking property and waterproofing property (unidirectional moisture permeability or moisture discharge function) are woven integrally by fiber yarns, the present invention is thinner than the conventional sewing type or adhesive type greenhouse insulating curtain. In addition to the low weight of the winding device as a switchgear device, as well as the existing thermal curtain, when the seam was broken, there was a problem that the thermal insulation curtain for the greenhouse was easily damaged and the opening and closing operation was not made smoothly. Greenhouse insulation curtains made of fabrics are structurally robust and can be used for many years economically even in farms, and their manufacturing process is completed by weaving process without going through many processes like conventional quilting or bonding method. Therefore, it has a useful effect of reducing the manufacturing cost compared to the quality.

Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

For reference, the accompanying drawings are shown in an inverted state in order to make expression easier.

As shown in Figures 1 to 4 in the present embodiment, the lower layer 10 woven with a weft 11 and a warp 12 made of a fiber yarn material such as polyester yarn or PET DTY yarn, and polyester yarn or The upper layer 20 to which the weft yarn 21 made of fiber yarn material such as PET DTY yarn and the inclined 22 made of aluminum strip yarn are woven, and the poly weave the lower layer 10 and the upper layer 20 so as to be integral with each other. It comprises a bonding yarn 30 made of a fiber yarn, such as ester yarn or PET DTY yarn.

The material of the heat insulating fabric according to the present embodiment is manufactured to be suitable for the thermal insulation curtain installed in the inside of the plastic house, and the weft yarns 11 and the warp yarns 12 forming the lower layer 10 are poly having heat absorbing hygroscopicity. An aluminum strip yarn, which is an ester yarn or PET DTY yarn, and an inclined 22 forming the upper layer 20, is an aluminum strip coated with a resin on the surface, and the weft yarn 21 is a yarn of polyester yarn or PET DTY yarn. Only the aluminum strip is exposed on the top, effectively blocking the inflow of outside air, moisture and light, and increasing the heat tightness inside the greenhouse to increase the insulation, and the moisture absorbed from the lower layer is pulled up through the weft of the upper layer connected by the joint. By raising and discharging to the outside, it is possible to maximize the insulation and dehumidification.

In addition, in the present embodiment, the bonding yarn 30 is also made of polyester yarn or PET DTY yarn, all of which are woven in one loom to form a single body.

In the present embodiment, the bonded yarn 30 is woven in a zigzag form between the weft yarn 11 of the lower layer 10 and the weft yarn 21 of the upper layer 20 to form a zigzag shape, thereby forming the lower layer 10 and the upper layer 20. It is to be combined integrally, whereby it is possible to manufacture a thin-walled insulation fabric having both thermal insulation (heat insulation) and waterproof and one-way moisture permeation function. Without going through the process of sewing, the lower layer mainly focusing on heat retention and hygroscopic function and the upper layer having waterproof and shading function can be made integrally, so that the durability can be improved and the curling and unwinding operation of the winding machine, which is a switchgear, can be made smoothly. Will be.

PET DTY used in the present invention is a draw textured yarn made of polyethylene terephthalate (polyethylene terephthalate) material, which is a stretch yarn or false twisted yarn by burning the filament in bulk, DTY spinning, stretching in one process In other words, it is a stretch yarn processed at the same time as a single machine, and literally means a processed yarn processed by a draw texturing machine.

In addition, the aluminum strip yarn used in the present invention is a thin aluminum file having a width of about 1 ~ 3mm, the surface is UV coated with a special resin, the aluminum strip yarn and the weft yarn 21 made of polyester yarn or PET DTY yarn and By forming the upper layer 20 to be orthogonal orthogonally, the greenhouse curtain made of the thermal insulation fabric of the present invention can increase the shade effect by radiating solar heat, and at the same time, the upper layer 20 is made of aluminum strip. Since the yarn and the weaving yarn are woven orthogonally, it is possible to secure improved breathability and moisture permeability compared to the aluminum screen made of aluminum strip yarn, so that the high temperature and excessive moisture inside the greenhouse can be discharged to the upper part of the thermal insulation curtain. It can be kept low and is suitable for growing crops An environment that will maintain the state can create.

In addition, the present invention in the night or winter when the temperature of the outside air is low, the lower layer 10 integrally woven in the lower portion of the upper layer 20 is made of fiber yarn, so that the heat is prevented from excessive release of heat inside the greenhouse to the outside In this case, the present invention has a heat insulating effect, and in particular, since the lower layer 10 having heat insulating property and the upper layer 20 having light blocking property and water resistance are woven integrally by the fiber yarn 30, the existing sewing type thermal insulation for greenhouse Compared to the curtain, the thickness of the curtain is lighter and the weight is less, and the load of the winding machine is less, and the existing insulation curtain has a problem that the greenhouse insulation curtain is easily damaged when the seam is broken, whereas the greenhouse insulation curtain of the present invention is structurally In addition, it can be used for many years economically in farms because it can be extended for a long time.
