## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. application Ser. No. 12/091,149, filed Apr. 22, 2008, which is a 35 USC §371 National Phase Entry Application from PCT/KR2007/003582, filed Jul. 26, 2007, and designating the United States, which claims priority under 35 U.S.C. §119 based on Korean Patent Application No. 10-2006-0117059 filed Nov. 24, 2006, which is incorporated herein in its entirety.


TECHNICAL FIELD
The present invention relates to a textile blind united by weaving, and in particular, to a textile blind formed of yarns, wherein the textile blind has a front textile, a back textile, and a slat textile for blocking lights, and each of the textiles is united with a front uniting part and a back uniting part by weaving a woof.
BACKGROUND ART
In general, curtains and blinds are installed on window or doorways of a building and are used for blocking solar light, external sight, noise and cold, and are also used as an important factor of indoor decoration for enhancing indoor beauty in accordance with combination of colors that can be harmonized with indoor walls or glasses.
The blind operates as follows. When a rope for pulling up or down the blind is pulled down, a reeling driver rotates in forward and backward directions, which leads to a forward and backward directional rotation of a reel pole so that a roll screen is rolled down from the reel pole or rolled up to adjust a degree of covering a window. However, such a method cannot adjust an amount of lights flowing indoor at all while the blind is pulled down across the entire window.
To cope with such a problem, several kinds of Venetian blinds using a plate-shaped slat are disclosed for adjusting lighting, however, the conventional Venetian blind not only has a complicated structure for adjusting brightness but also has a very burdensome adjusting function and a high cost unit of manufacture.
Further, the Venetian blind is formed of metal or wood instead of a conventional synthetic resin due to an upgrade of the slat, which causes the blind to be much weighted so that it is difficult to install the blind.
In a case of a conventional textile blind 20 shown in FIG. 1 among such blinds as described above, a textile slat 23 is formed between a front side 21 and the back side 22 by means of thermal treatment, and an adhered part 24 bonded by the thermal treatment is fallen apart at this time when it is exposed to solar lights for a long period of time, so that the blind cannot properly act its own function.

BEST MODE
The present invention provides a textile blind united by weaving, which includes a front textile, a back textile in parallel with the front textile, and a slat textile having a predetermined width along a width between the front and back textiles, wherein both ends of the slat textile are united with the respective front and back textiles by weaving to form respective front uniting and back uniting parts, a plurality of the slat textiles are arranged along a height of the front and back textiles, and the front uniting part of one slat textile has the same height as the back uniting part of an adjacent slat textile, so that the textile blind configured as described above is applied to a typical blind structure to facilitate installment, adjustment, blocking solar lights and lighting.
According to the textile blind 10 of the present invention, as shown in FIGS. 4 to 6, warps are woven by woofs to form a front textile 12 and a back textile 13 for ventilation, and a plurality of slat textiles 14 for blocking lights, respectively, thereby resulting in the textile blind 10. Each of the slat textiles 14 is united with the front textile 12 and the back textile 13 along both ends of its longitudinal direction to form respectively front uniting part 15 and back uniting part 16.
Such a textile blind 10 will now be described in detail with reference to accompanying drawings.
The front textile 12 and the back textile 13 for ventilation and light adjustment are first woven by warps and woofs, respectively. Each of the plurality of slat textiles 14 capable of blocking lights is woven by slat warp 17 and slat woof as shown in FIGS. 2 and 3.
Then, the front textile 12, the back textile 13, and first slat textile 14 are woven by first slat warp 17 and are united with each other by the first front uniting part (see FIG. 6) and the first back uniting part 16 by weaving. That is, they are united with each other by the first front uniting part 15 and the first back uniting part 16 in up and down directions.
Then, the first slat warp 17 is passing through weaving holes 18 formed in a second front uniting part 15 after forming the first back uniting part 16 while an end of a second slat warp 17 united with the second front uniting part 15 is woven by the woof of a second back uniting part 16.
In other word, the second slat warp 17 is first united with the second front uniting part 15 and then is further woven to form the second back uniting part (see FIG. 6). The second slat warp 17 is further woven with woof to form a second slat textile 14 which is capable of blocking lights and connecting between the second front uniting part 15 and the second back uniting part as shown in FIG. 6. Such a weaving process is repeatedly performed.
In more detail, a plurality of the slat textiles 14 are arranged along the height direction (i.e., weaving direction) of the front textile 12 and the back textile 13 in the process as described above. The second front uniting part 15 formed at an end of the second slat textile 14 is disposed at the same level as the first back uniting part 16 united with the first slat textile 14 which is formed next to the second slat textile 14, The first slat textile 14 is overlapped with the second front uniting part 15 and the first back uniting part 16 as shown in FIGS. 2, 3 and 5 when the textile blind 10 is in a flattened state. The slat textile 14 has an area almost equal to the area of the front textile 12 or the back textile 13 on the whole, thereby blocking lights.
Preferably, each of the slat textiles 14 for the textile blind 10 has a width of 30 to 70 mm to minimize hanging-down of the slat textiles 14 and improve an aesthetic sense.
In other words, warps are united with respective woofs by weaving to form the front textile 12, the back textile 13, and the slat textile 14 as one body. In more detail, the front textile 12, the back textile 13, and the first slat textile 14 are woven by the first slat warp 17 to form the first front uniting part 15 and the first back uniting part 16 by weaving. Likewise, the second slat warp 17 is united with the respective woofs by weaving to allow the front textile 12, the back textile 13, and the second slat textile 14 to be united with each other in up and down directions.
The first slat warp 17 is passing through weaving holes 18 formed in the second front uniting part 15 after being united with the first back uniting part 16 while the second slat warp 17 united with the second front uniting part 15 is woven by the woof of the second back uniting part 16, thereby configuring the textile blind 10 united by weaving as shown in FIG. 4.
In other words, the front textile 12 and the back textile 13 are woven with the warps and the respective woofs. The slat textiles 14 are woven with the slat warps 17 and slat woofs. In the front uniting parts 15 and the back uniting parts 16, the slat warps 17 are woven with separate woofs.
Accordingly, the textile blind 10 having the shape as shown in FIG. 4 can be formed. The slat warps 17 are exposed to an external side. The slat warps 17 exposed over the front textile 12 are cut based on the front uniting part 15 or the back uniting part 16 after it is completely united by weaving. As a result, the textile blind 10 is configured as shown in FIG. 5. Meanwhile, the front textile 12 and the back textile 13 have a mesh structure to facilitate ventilation, and each of the slat textiles 14 has a mesh structure to allow external sights to be viewed while lights are not blocked. As such, each of the warps for weaving the front textile 12, the back textile 13, the slat textiles 14, the front uniting parts 15, and the back uniting parts 16 is composed of a synthetic fiber, and has a thickness of 50 to 1500 (denier).
The woof for weaving the front textile 12 and the back textile 13 is composed of a low melt fiber, and has a thickness of 50 to 1500.
In addition, the woof for weaving each of the slat textiles 14 is composed of two threads, that is, a synthetic fiber and a low melt fiber, and the synthetic fiber has a thickness of 270 to 3500 and the low melt fiber has a thickness of 50 to 1500.
The woof for weaving each of the front uniting parts 15 and the back uniting parts 16 is composed of two threads, that is, a synthetic fiber and a low melt fiber, and the synthetic fiber has a thickness of 280 to 3500 and the low melt fiber has a thickness of 50 to 1500.
Thickness and material of warps and woofs of the textile blind 10 as described above are represented in the table 1 below.

For reference, the low melt fiber used as each woof of the front textile 12, the back textile 13, the slat textiles 14, the front uniting parts 15, and the back uniting parts 16 is made of a low melt fiber having a melting point of 170 to 220 degrees Celsius (° C.). This is because that the low melt fiber is bonded with the warps such as a synthetic fiber at its melting point due to its characteristic to maintain the respective woven structures, and is not deformed even when an external force is applied, so that the textile blind 10 woven as described above is fixed to maintain its shape by means of melting bond when heat of 170 to 220 degrees Celsius (° C.) is applied thereto by a separate Tenter.
In addition, each woof for weaving the front textile 12, the back textile 13, the front uniting parts 15, and the back uniting parts 16 is mixed (covered) with a rubber thread to prevent folds from occurring after the textile blind is manufactured.
In addition, the textile blind 10 undergoes a flame-retardant treatment so that it is safe against fire. To this end, threads used for the warps and the woof of the front textile 12, the back textile 13, the slat textiles 14, the front uniting parts 15, and the back uniting parts 16 undergo a flame-retardant treatment, or have a property safe against fire configured such that the textile blind is put into a flame-retardant liquid before the woven textile blind 10 is processed by the Tenter.
The front textile 12 and the back textile 13 preferably have a mesh structure, and spaces generated by the mesh structure of the front textile 12 and the back textile 13, instead of having all square shapes, have square holes generated by the mesh structure of one of the front textile 12 and the back textile 13, and holes generated by the mesh structure of the other of the front textile 12 and the back textile 13 with a ratio of 1 by 1.5 to 2.5, thereby preventing a moire phenomenon.
Consequently, when the textile blind 10 is completely woven by the warps and the woofs as shown in FIG. 4, the slat warps 17 are externally opened. The front textile 12 and the back textile 13 face each other and the slat textiles 14 therebetween are successively formed in up and down directions. Heat generating from a Tenter is applied to the textile blind 10 by means of melting bond. Both ends of the textile blind 10 are cut and finished. The protruded slat wraps 17 are removed. The textile blind 10 configured to have the desired length and width again is applied to the conventional blind structure, which is typically used in the same way as the related art as shown in FIGS. 7 to 9.
Accordingly, the textile blind 10 formed as described above is assembled with a separate blind cover, and a support matching the width of the slat textiles 14 is fixed at a lower position of the textile blind 10 to prevent shaking after the textile blind 10 is mounted as shown in FIG. 7.
In this case, when the slat textiles are raised as shown in FIG. 8, that is, when the slat textiles 14 maintain a vertical state with respect to the bottom (i.e., flattened state), the slat textiles 14 are in close contact with the front textile 12 and the back textile 13 to block external lights.
In addition, when the slat textiles 14 are raised as shown in FIG. 8, the textile blind 10 maintains a plane state, so that the textile blind 10 can be rolled up or out as shown in FIG. 7.
When the slat textiles 14 are pulled down as shown in FIG. 9, that is, when the slat textiles 14 are pulled down until a horizontal state (or the plane state) is maintained on upper sides of the slat textiles 14 between the front textile 12 and the back textile 13, the front textile 12 and the back textile 13 become apart from each other, so that a ventilation structure can be generated to allow external airs to circulate through a mesh structure of the front textile 12 and the back textile 13. Thus, external sights can be viewed through the mesh structure, and lights can be taken in.
For reference, when the textile blind 10 maintains lighting, the slat textiles 14 between the front textile 12 and the back textile 13, instead of having a completely vertical shape, has an arc shape in the position near the front uniting part 15 and the back uniting part 16 when seen in a side view as shown in FIG. 6.
According to the present invention as described above, the front and back textiles for ventilation and the slat textiles for blocking lights can be simultaneously woven to form a textile blind 10 having several slat textiles 14.
INDUSTRIAL APPLICABILITY
Such a textile blind can be united by a weaving machine using the above described method, and can be manufactured and supplied to allow consumers to easily install and use the textile blind.
