The present invention relates to a window shade for controlling the amount of light made of fabric and a method of manufacturing the same. More specifically, the window light for adjusting the amount of light made of fabric and excellent in draping ability to easily adjust the amount of light passing through the window and having such characteristics It's about how to make a window shade simpler.

Generally, window shades for light control are used in homes, hotels, restaurants and other buildings to protect the privacy of the interior and block the sun.In general, curtains, vertical or horizontal verticals, and a certain width of the fabric are cut and rolled. Roll screens or panel screens are used, which are rolled up and fixed to a window so that the user can unwind the roll to cover the window or roll the roll to secure the view. Each of these different types of window shades has its own strengths and weaknesses. For example, curtains are generally fabrics, which give a refined and cozy feel to the interior, while being inconvenient in cost and care, and vertical. Or horizontal vertical rolls or roll screens are simple to install and convenient to use, but they are not classy. In particular, conventional verticals have a disadvantage in that they are not fabricated because they are generally not fabrics.

Therefore, a new type of window shade has been proposed to solve the above problems. In detail, a vertical type of window shades made of a fabric that combines the advantages of curtains of fabrics that soften the atmosphere of the room and the advantages of verticals with ease of use have been proposed. Compared with blinds, it provides a softer appearance and easier handling.

A new type of window shader in the vertical form of textiles proposed to solve the conventional problems as described above is, for example, US Patent No. 3,384,519. The window shade presented in this patent consists of two fabric layers spaced by movable parallel blades with each edge of a heat welded edge on one of the movable fabric layers, the relative movement of the two fabric layers in a direction perpendicular to the blade. Consists of a window shade that modifies the angle of the blade to control the amount of light entering the article. However, the window shade disclosed in the patent is limited to the use of heat-welding fabrics, that is, mutually suitable thermoplastic materials, because the window shader is configured using a heat welding process, and heat welding must also melt at least some of the fibers of the bonded material. There were disadvantages such as weak fabric structure.

Therefore, to solve the problems of the conventional patent, Korean Patent Application No. 193-0006097, "Method and Apparatus for Manufacturing Window Cover of Light Control Fabric", has been proposed. The Republic of Korea Patent Application No. 199-0006097 discloses "a first sheet material, a second sheet material disposed in parallel to the first sheet material, at least one of the sheets is porous, and a plurality of strip materials are respectively opposed to the opposite surface and the An adhesive adhesive having opposing edge portions in contact with each opposing surface and adhering the strip along the opposing edge portions to the sheet material such that the adhesive is injected into at least one of the sheet materials so that the line of sight is clearly visible. Means, the visible adhesive line having a matte appearance, the central portion of the strip being substantially planar in the first enclosed state of the window covering and extending substantially parallel to the first and second sheet materials; In the second open state of the window cover, there is a light control window cover " It discloses a Johann configuration.

However, the method of the Republic of Korea Patent Application No. 1993-0006097 still does not deviate from the basic configuration of the bonding, although the conventional problem to be solved, although solving the conventional problem, the manufacturing process is cumbersome only by using the adhesive by the adhesive method However, the manufacturing cost increases, and there is a fear that harmful substances may be released for a long time due to the use of adhesives, and the durability of the adhesive force may drop sharply under the influence of light or temperature. There is still a disadvantage that the part is short-circuited to shorten the life of the window cover.

Accordingly, an object of the present invention is to provide a fabric light quantity control window shader that solves the problems caused by the complicated manufacturing process and adhesive use, which is a problem in the conventional fabric light quantity control window shade configured as described above.

It is another object of the present invention to provide stiffness in a simple manner, thereby providing excellent drapeability, which is an important feature as a window shade, while not losing the original texture by not using conventional methods such as coating, And to provide a window shade for controlling the amount of light of the fabric is not deformed by humidity.

Another object of the present invention is to provide a manufacturing method of the window shade for controlling the light quantity of the textile having the above characteristics.

The object of the present invention is to weaving the transparent portion and the opaque portion of the window shade together at a certain portion together and weaving by repeating the method of weaving separately at other portions, and also the weft of the opaque portion LM different in the melting point of the center and the outer portion It was achieved by providing a method of manufacturing a window stiffener excellent in rigidity by a simple weaving method by heat treatment after weaving using a yarn.

Here, the weaving step is formed of an upper transparent layer, an intermediate opaque layer and a lower transparent layer, the upper transparent layer is woven together at a predetermined width with a middle opaque layer at a predetermined interval by the yarn A used only in the slope in the middle opaque layer, The lower transparent layer is woven together with the middle opaque layer at a certain width by a yarn A used only as a slope in the middle opaque layer, and the upper transparent layer and the lower transparent layer are constant so that each of the weft and the slope can transmit light. It is woven at intervals so as to be woven from the outside so that the opaque layer is characterized in that the light is densely woven so as not to transmit.

According to another configuration of the present invention, the interval between the weft and the inclination of the upper and lower transparent layers is characterized in that 0.2 to 2mm. If it is 0.2 mm or less, it is not preferable because it loses transparency and loses the function of adjusting the amount of light transmitted.

The window shade for adjusting the amount of light of the present invention can be easily manufactured by forming the upper and lower transparent layers and the intermediate opaque layer together at a predetermined position and integrally formed as described above. . In addition, the window shade according to the present invention is heat-treated at a certain temperature after the LM yarn is used as the weft yarn, and then heat-treated at a constant temperature, the low melting point polyester of the outer portion of the LM yarn is melted and flows, and mutually melted with other LM yarn around, Immediately cooled, the molten polyester is cured and stiff, providing stiffness to the window shades, thereby providing excellent drape properties, an important feature as window shades. In addition, in order to impart drape property, the original texture is not lost because no conventional coating or the like is used, and deformation due to temperature and humidity does not occur.

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

1 is a schematic perspective photograph of a window shade for adjusting the light quantity of a textile according to the present invention. As shown in FIG. 1, the window shade 1 according to the invention consists of an upper transparent layer 11, a lower transparent layer 12 and an intermediate opaque layer 13. First, the warp and weft of the transparent layer is to prepare a polyester yarn and to perform the longitude work to install the yarn in the longitudinal steel and the body in order to work and weave. Weaving was performed using LM as the weft of the opaque layer. Weaving was performed to form a plurality of intermediate opaque layers 13 between the weft and the upper transparent layer 11, the lower transparent layer 12, and the upper and lower transparent layers. Specifically, between the upper transparent layer 11 and the lower transparent layer 12, one end is connected to the upper transparent layer 11 by the A yarn 131 used only as a slope in the middle opaque layer 13, the upper connection surface And a second end is connected to the lower transparent layer 12 to form a lower connection surface 121, and the middle opaque layer 13 between the upper and lower connection surfaces 111 and 121 is an upper transparent layer. It was woven so as to be interposed between 11 and the lower transparent layer 12. That is, by using the longitudinal steel 3, 6, 9, 12 of the weaving machine, weaving the void part and the connecting surface 111, and the longitudinal steel 1, 2, 5, 8, 11, 14 of the weaving machine To woven the intermediate opaque layer 13.

In addition, the upper transparent layer 11 and the lower transparent layer 12 are woven so that the distance between each of the weft and the inclination is 0.5 mm so that the light can be transmitted sufficiently to be woven from the outside to view, the opaque layer 13 ) Was densely woven so that light could not be transmitted.

Next, the woven window shade woven as described above was heat-treated at 170 ° C. to impart quench and physical properties suitable for use as the window shade to LM yarn used for warp and weft yarns. After the heat treatment as described above, the A yarn 131 used as the fabric edge and the inclination was cut and rolled after shearing processing.

Figure 2 is a schematic side cross-sectional view of the fabric light amount control window shade of the present invention, the closed state before the yarn A cut, Figure 3 is a schematic side cross-sectional view of the fabric light amount control window shade of the present invention, the open state after the yarn A cut to be. As shown in FIG. 2, the yarn A 131 is used as the inclination of the intermediate opaque layer 13 so that the upper transparent layer 11 and the intermediate opaque layer 13 are woven together at a predetermined distance on the upper connecting surface 111. And then proceed to the lower connecting surface 121 in a non-weaving state and then to the lower transparent layer 12 and the intermediate opaque layer 13 are woven together a certain distance from the lower connecting surface 121, In the end of the lower connection surface 121 is used as an inclination of the intermediate opaque layer 13, and then proceeds, the upper transparent layer 11 and the intermediate opaque layer 13 in the upper connection surface 111 to weaving a certain distance together Repeat. Therefore, after weaving is completed, the yarn A 131 remains from the upper connection surface 111 to the lower connection surface 121 as shown in FIG. 2, so that the yarn A is not cut in the state of being cut. This prevents the upper transparent layer 11 and the lower transparent layer 12 from moving in opposite directions, so that the intermediate opaque layer 13 is positioned at right angles between the upper and lower transparent layers 11 and 12, as shown in FIG. Since it cannot be spaced, it cannot function as a window shader. Therefore, the upper transparent layer 11 and the lower transparent layer 12 are separated by cutting the A yarn 131 to form the space 132 as shown in FIG. 3.

When the A yarn 131 cut as described above remains cut out on the surface, it was cleaned using a shearing machine.

In addition, in the present invention as described above, by using the LM yarn having a cross section as shown in FIG. It can be manufactured.

Fabric light control window shade of the present invention is configured as described above can be easily manufactured by forming the upper and lower transparent layer and the opaque layer of the middle is integrally woven together in a certain area as well as environmentally friendly using no adhesive. There is no fear that the connection surface of each layer will be short-circuited and can be used semi-permanently. In addition, the window shade according to the present invention is excellent in the drape property, which is an important feature as a window shade without losing the original texture without using a method such as coating because it is heat-treated at a constant temperature after LM is used as a weft weaving It is a useful invention without deformation by temperature and humidity.
