Description

[Technical field]

[0001] The present invention relates to an improvement in light-blocking fabrics, and more specifically to a decorative light-blocking fabric that has excellent light-blocking performance while maintaining the original hue of the decorative pattern on the surface, thereby achieving high aesthetic appeal, and that can be manufactured in a single weaving process, and a curtain using the same. [Background technology]

[0002] Woven fabrics using black dyed yarn for the warp or weft are known as fabrics used for blackout curtains to block out sunlight and other rays (see, for example, Patent Document 1). However, because curtains are used indoors, if the black color of the black dyed yarn is exposed inside the room, it has the side effect of darkening the atmosphere inside the room rather than just physically suppressing the light intensity.

[0003] In this case, it is considered to add a pattern to the surface (indoor side) of the light-blocking fabric, but if the black dyed thread is exposed, the color of the pattern will mix with the black color, resulting in a dull color that does not express the original hue, and there has been dissatisfaction that the decorative effect cannot be fully expressed.

[0004] In response to this, a method has been disclosed in which white thread is placed on the surface of a light-blocking fabric and a pattern is formed on top of it by printing, thereby imparting decorativeness and aesthetic appeal (see Patent Document 2).

[0005] However, the invention of <Patent Document 2> requires investment in equipment such as a transfer device for the printing process, and the processing time is also long, resulting in an increase in manufacturing costs.

[0006] Also, as a means to prevent the influence of the black color, a light-blocking fabric and a patterned fabric are bonded together with an adhesive sheet (see Patent Document 3).

[0007] However, in the invention of <Patent Document 3>, the presence of the adhesive sheet impairs the drape of the curtain, and it is difficult to peel off the adhesive sheet and to produce large pieces of fabric, resulting in problems such as increased manufacturing effort and cost.

[0009] The present invention has been made in consideration of the above-mentioned problems in the prior art, and its object is to provide a decorative light-blocking fabric and a curtain using the same which have excellent light-blocking performance while maintaining the original hue of the decorative pattern on the surface, thereby providing high aesthetic appeal, and which can be manufactured in a single weaving process. [Means for solving the problem]

[0010] The means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

[0011] That is, the present invention provides a basic woven fabric part having a three-layer woven fabric structure of a surface layer 1, an intermediate layer 2, and a back layer 3, The basic woven fabric portion has a three-layer structure of a double warp weave consisting of the weft yarns 21 of the intermediate layer 2, the warp yarns 11 of the surface layer 1 on both sides thereof, and the warp yarns 31 of the back layer 3, and the weave of the surface layer 1 is a warp satin weave. The weft yarn 21 of the intermediate layer 2 Black The warp yarn 11 of the surface layer 1 is white The yarn is then processed into a false twist yarn. The thickness of the warp yarns 11 of the surface layer 1 is made thicker than the thickness of the weft yarns 21 of the intermediate layer 2, The warp threads 11 of this surface layer 1 Between tissue pointsThe weft yarn 21 is covered by the swelling to prevent the weft yarn 21 from being exposed to the surface layer 1 side. A decorative light-shielding fabric is completed by adopting a technical means of weaving a decorative pattern layer 4 of a woven fabric integrally with the surface layer 1 of the basic woven fabric part, thereby preventing the addition of color of the weft thread 21 to the hue of the warp and weft threads constituting the decorative pattern layer 4.

[0015] Furthermore, in order to solve the above problems, the present invention can also adopt, in addition to the above means, a technical measure in which the basic woven fabric part having a three-layer structure with a double warp weave is made into a double-sided satin weave, if necessary.

[0017] In addition, the present invention provides a method for manufacturing a decorative light-shielding fabric of the intermediate layer 2 using the decorative light-shielding fabric constructed by the above-mentioned means. Black It is also possible to adopt a technical measure in which the dope-dyed weft yarns 21 are arranged horizontally to form a curtain.

[0018] In addition, in order to solve the above problems, the present invention can also adopt, in addition to the above means, a technical measure in which a mounting fixture can be arranged at the upper end so that the decorative pattern layer 4 faces the interior side, as necessary. Effect of the Invention

[0019] In the present invention, a basic woven fabric part is constructed with a three-layer woven fabric structure of a surface layer, an intermediate layer, and a back layer, the weft of the intermediate layer is a dark colored dope-dyed yarn, and the warp of the surface layer is a light colored false twisted yarn, and the weft is covered by the expansion of the warp of the surface layer, thereby preventing the exposure of the weft to the surface layer side. By weaving the decorative pattern layer of a weave structure integrally onto the surface of the surface layer of the base woven fabric portion, it is possible to prevent the color of the weft yarns from being mixed with the color of the warp yarns constituting the decorative pattern layer.

[0020] Therefore, the decorative light-shielding fabric of the present invention has excellent light-shielding performance while maintaining the original hue of the decorative pattern on the surface, thereby providing high aesthetic appeal.

[0021] Furthermore, since the base woven fabric portion and the decorative pattern layer are integrated into a single piece of fabric, the fabric can be manufactured in a single weaving process using a single loom.

[0022] If necessary, the basic woven fabric part can be made into a three-layer structure with a double warp weave consisting of a middle layer of weft yarns and surface warps and a back layer of warp yarns on both sides of the middle layer, thereby reducing the amount of yarn used and achieving excellent drape properties, which can be said to have great industrial value. [Brief description of the drawings]

[0023] [Figure 1] 1 is a schematic cross-sectional view showing the structure of a decorative light-shielding fabric according to an embodiment of the present invention. [Diagram 2] 1 is a cross-sectional view showing the weave of a decorative light-shielding fabric according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] An embodiment of the present invention will be described with reference to Figures 1 and 2. In the figures, reference numeral 1 indicates a surface layer, reference numeral 2 indicates a middle layer, reference numeral 3 indicates a back layer, and reference numeral 4 indicates a decorative pattern layer.

[0025] The decorative shading fabric of this embodiment is a multilayer fabric having two parallel surfaces, a basic woven fabric part and a decorative pattern layer.First, we will explain the structure of the basic woven fabric part, which has a three-layer woven fabric structure consisting of a surface layer 1, an intermediate layer 2, and a back layer 3.

[0026] In this embodiment, polyester can be used as the material for the warp and weft threads in the basic woven fabric portion, and the thread thickness can be in the range of 50 to 500 dtex.

[0027] The weft yarn 21 of the intermediate layer 2 is a dark colored dope-dyed yarn, and the warp yarn 11 of the surface layer 1 is a light colored false twisted yarn. The dope-dyed yarn is a colored synthetic yarn produced by kneading a dope dye and a coloring agent into the raw material during spinning, and while the surface of a normal yarn is colored by dyeing, the dope-dyed yarn is colored not only on the surface but also in the core. The dark color is preferably black, which absorbs visible light best, but may be other colors such as navy blue or red.

[0028] In this embodiment, the light color of the warp threads 11 of the surface layer 1 can be a white-based thread. This allows the original hue of the decorative pattern layer 4 to be more faithfully reproduced. Note that the light color can be a light color or beige, etc., as long as it has low saturation.

[0029] The false twist textured yarn used for the warp yarns 11 of the surface layer 1 is a yarn in which a crimped form is given to filament yarns such as polyester or nylon by utilizing the thermoplasticity of chemical fibers, thereby imparting bulk and elasticity. Usually, the yarn is heated in a twisted state, then cooled to fix the twist deformation in the fibers, and then twisted in the opposite direction to the twisting direction to produce a bulky, elastic yarn without twist.

[0030] The weft yarn 21 is covered by the swelling of the warp yarn 11 of the surface layer 1, preventing the weft yarn 21 from being exposed to the surface layer 1. In other words, since the warp yarn 11 is a false twist textured yarn, the bulkiness of the yarn can be utilized to swell and cover between the weaving points.

[0031] Furthermore, a decorative pattern layer 4 made of a weave is woven integrally onto the surface of the outer layer 1 of the basic woven fabric part. This decorative pattern layer 4 can be woven integrally into the weave of the basic woven fabric part by weaving the warp threads into the weave of the basic woven fabric part using a single loom. Furthermore, the decorative pattern layer 4 is not restricted by the thickness of the threads or the weave of the basic woven fabric part, and may be a satin weave, twill weave, or plain weave, and the color and thickness of the threads can be freely selected.

[0032] Furthermore, by weaving the decorative pattern layer 4 into the surface layer of the basic woven fabric portion as warp and weft threads separate from the basic weave, it is not affected by the additive color mixing of dark colors (black), and therefore it is possible to prevent the additive coloring of the weft thread 21 to the hue of the warp and weft threads that make up the decorative pattern layer 4.

[0033] In this embodiment, the thickness of the warp yarns 11 of the surface layer 1 can be made thicker than the thickness of the weft yarns 21 of the intermediate layer 2. By doing so, the exposed weft yarns 21 of the intermediate layer 2 that are adjacent and perpendicular to each other can be reliably covered.

[0034] In this embodiment, the base woven fabric part can have a three-layer structure with a double warp weave consisting of the weft 21 of the intermediate layer 2, the warp 11 of the front layer 1 on both sides thereof, and the warp 31 of the back layer 3 (see FIG. 2). The double warp weave is a weave consisting of double warp and single weft, with the warp coming out on the front and back sides. In this case, the weft 21 of the intermediate layer 2 is present inside the base woven fabric part, so the warp 11 and the warp 31 come out on the front and back sides of the front layer 1 and back layer 2. This allows a small amount of thread to be used, the fabric to have a low density, and excellent light blocking and drape properties to be obtained.

[0035] In this embodiment, the basic woven fabric portion having a three-layer structure with double warp weave can be made into a double-sided satin weave (satin weave), which can improve the texture and drape of the fabric.

[0036] Furthermore, in this embodiment, the weave of the surface layer 1 of the basic woven fabric part, which is made of a three-layer structure with a double warp weave, can be a warp twill weave. In a warp twill weave, the warp threads jump more than the weft threads, so that the warp threads 11 of the surface layer 1 are exposed to the surface in large amounts. However, by covering the weft threads 21 of the middle layer 2 in the surface layer 1, the exposure can be prevented more reliably.

[0037] In addition, in this embodiment, the decorative light-shielding fabric constructed as described above can be used to form a curtain in which the dark-colored dope-dyed weft threads 21 of the intermediate layer 2 are arranged horizontally. In this way, the weft threads 21 themselves cast shadows on the threads directly below them with respect to the angle of sunlight, eliminating sunlight leaking through gaps and enabling more effective light shading.

[0038] In addition, the curtain of this embodiment can be configured so that a mounting tool can be attached to the upper end so that the decorative pattern layer 4 faces the room side. This allows the installation direction of the curtain to be specified vertically, horizontally, and front to back, and ensures the above-mentioned light blocking effect and decorative pattern effect.

[0039] The present invention is generally configured as described above, but is in no way limited to the illustrated embodiments, and various modifications are possible within the scope of the claims. For example, the three-layer woven fabric structure of the base woven fabric part, consisting of a surface layer 1, a middle layer 2, and a back layer 3, may be a woven fabric structure in which each layer is woven with warp and weft yarns, and falls within the technical scope of the present invention.
