CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the priority benefit of China Application Serial No. 201721774046.4, filed on Dec. 18, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this application. 
     BACKGROUND 
     Technical Field 
     This invention relates to a woven fabric and, more particularly, to a fabric for heat insulation by reflecting sunlight and a curtain made of the fabric. 
     Description of Related Art 
     By arranging a curtain at an inner side of a window, not only an external sight is isolated to protect privacy in a room, but also in the summer, part of the sunlight is blocked to avoid the sunlight being directly irradiated into the room to achieve the purpose of heat insulation. In order to achieve a better heat insulation effect, multi-layer curtains are usually arranged, which make the curtains look redundant. 
     SUMMARY 
     An object of this invention is to provide a heat insulation fabric which can effectively reflect ultraviolet rays and infrared rays in sunlight to achieve heat insulation. 
     The other object of this invention is to provide a heat insulation curtain which can effectively reflect the infrared rays and the ultraviolet rays in the sunlight to achieve the heat insulation. 
     To achieve the above-mentioned object, this invention provides a heat insulation fabric including a base cloth interwoven via a warp thread and a weft thread. The warp thread is a flat aluminum thread, the weft thread is a polyester yarn or a polyester filament, and the base cloth is woven by the warp thread and the weft thread in a satin weave or a twill weave. 
     The base cloth woven from the flat aluminum thread as the warp thread and the polyester yarn or the polyester filament as the weft thread is adopted, thereby ensuring that the flat aluminum thread remains in a straight line state after being woven into the base cloth. What&#39;s more, the twill weave or the satin weave is adopted to effectively ensure that the majority of cloth surface of the base cloth being a warp-faced weave is pieced by a flat surface of the flat aluminum thread maintaining the straight line state. When one surface of the warp-faced weave is arranged toward the sun, that is, a light-facing surface is constructed, thus the infrared rays and the ultraviolet rays in the sunlight are effectively reflected to ensure a heat insulation effect of the heat insulation fabric. 
     A specific solution is that the base cloth has a warp-direction density of 26 and a weft-direction density of 18 to 25. 
     Another specific solution is that the flat aluminum thread is a flat aluminized polyester continuous filament, and the polyester filament is a polyester continuous filament. 
     A preferred solution is that the satin weave is a 5/3 weft-faced satin. A five heddle satin having a compact structure is adopted, and a warp thread arrangement density is combined to make the warp thread woven on one surface of the fabric form the warp-faced weave, to effectively ensure a blocking effect of this heat insulation fabric to the infrared rays and the ultraviolet rays in the sunlight. 
     Another preferred solution is that the twill weave is a 1/3 twill. The 1/3 twill having a compact structure is adopted, and the warp yarn arrangement density is combined to make the warp thread woven on one surface of the fabric form the warp-faced weave, to effectively ensure the blocking effect of this heat insulation fabric to the infrared rays and the ultraviolet rays in the sunlight. 
     To achieve the other above-mentioned object, this invention provides a heat insulation curtain including a base cloth interwoven via a warp thread and a weft thread. The warp thread is a flat aluminum thread, and the weft thread is a polyester yarn or a polyester filament. The base cloth is woven by the warp thread and the weft thread in a satin weave or a twill weave. A light-facing surface of the base cloth is a warp-faced weave. 
     The base cloth woven from the flat aluminum thread as the warp thread and the polyester yarn or the polyester filament as the weft thread is adopted, thereby ensuring that the flat aluminum thread remains in a straight line state after being woven into the base cloth. What&#39;s more, the twill weave or the satin weave is adopted to effectively ensure that the majority of cloth surface on the light-facing surface which is the warp-faced weave is pieced by a flat surface of the flat aluminum thread maintaining the straight line state. The infrared rays and the ultraviolet rays in the sunlight are effectively reflected to ensure a heat insulation effect of the heat insulation curtain. 
     A specific solution is that the base cloth has a warp-direction density of 26 and a weft-direction density of 18 to 25. 
     Another specific solution is that the flat aluminum thread is a flat aluminized polyester continuous filament, and the polyester filament is a polyester continuous filament. 
     A preferred solution is that the satin weave is a 5/3 weft-faced satin. A five heddle satin having a compact structure is adopted, and a warp thread arrangement density is combined to make the warp thread woven on the light-facing surface of the heat insulation curtain form the warp-faced weave, to effectively ensure a blocking effect of this heat insulation curtain to the infrared rays and the ultraviolet rays in the sunlight. 
     Another preferred solution is that the twill weave is a 1/3 twill. The 1/3 twill having a compact structure is adopted, and the warp yarn arrangement density is combined to make the warp thread woven on the light-facing surface of the heat insulation curtain form the warp-faced weave, to effectively ensure the blocking effect of this heat insulation curtain to the infrared rays and the ultraviolet rays in the sunlight.

     DESCRIPTION OF THE EMBODIMENTS 
     This invention will be further described below in combination with embodiments and accompanying drawings. 
     Heat Insulation Fabric of a First Embodiment 
     See  FIG. 1  and  FIG. 2 , the heat insulation fabric of this embodiment includes a base cloth  2 , and the base cloth  2  is woven by a warp thread and a weft thread in a satin weave  1  shown in  FIG. 1 . The warp thread adopts a flat aluminum thread  12 , the weft thread adopts a polyester filament  11 , and the satin weave  1  is woven by a rapier loom. In this embodiment, the flat aluminum thread  12  adopts a  90 D flat aluminized polyester continuous filament, and the polyester filament  11  adopts a  300 D polyester continuous filament. A warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 18. 
     As shown in  FIG. 1 , the satin weave  1  is a 5/3 weft-faced satin, and a flat surface of the flat aluminum thread is arranged toward a surface of the base cloth. On the base cloth  2 , the flat aluminum thread serving as the warp thread does not bend and remains in a straight line state, and the polyester filament serving as the weft thread has less cover to the flat aluminum thread, thereby forming a warp-faced weave on one surface of the base cloth, and the majority area of the warp-faced weave is pieced by the flat surface of the flat aluminum thread. 
     As shown in  FIG. 2 , during usage, one surface of the base cloth  2  which is the warp-faced weave faces toward the sun, such that most of ultraviolet rays and infrared rays in the sunlight irradiated on the surface of the cloth are directly reflected off, and part of the remaining ultraviolet light and infrared light are absorbed by the heat insulation fabric and are sent to a space at a light-facing side of the heat insulation fabric in a radiation way. Therefore, the ultraviolet rays and the infrared rays transmitted into the backward-light side through the heat insulation fabric are effectively reduced, that is, the ultraviolet rays and the infrared rays in the sunlight are effectively blocked to achieve a good heat insulation effect. 
     Heat Insulation Fabric of a Second Embodiment 
     See  FIG. 2  and  FIG. 3 , the heat insulation fabric of this embodiment includes a base cloth  2 , and the base cloth  2  is woven by a warp thread and a weft thread in a twill weave  3  shown in  FIG. 2 . The warp thread adopts a flat aluminum thread  32 , the weft thread adopts a polyester yarn  31 , and the twill weave  3  is woven by the rapier loom. In this embodiment, the flat aluminum thread  32  adopts a flat aluminized polyester continuous filament. A warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25. 
     As shown in  FIG. 3 , the twill weave  3  is a 1/3 twill, and a flat surface of the flat aluminum thread is arranged toward a surface of the base cloth. On the base cloth  2 , the flat aluminum thread serving as the warp thread does not bend and remains in a straight line state, and the polyester staple filament serving as the weft thread has less cover to the flat aluminum thread, thereby forming a warp-faced weave on one surface of the base cloth, and the majority area of the warp-faced weave is pieced by the flat surface of the flat aluminum thread. 
     As shown in  FIG. 2 , during usage, one surface of the base cloth  2  which is the warp-faced weave faces toward the sun, such that most of the ultraviolet rays and the infrared rays in the sunlight irradiated on the surface of the cloth are directly reflected off, and part of the remaining ultraviolet light and infrared light are absorbed by the heat insulation fabric and are sent to space at a light-facing side of the heat insulation fabric in a radiation way. Therefore, the ultraviolet rays and the infrared rays transmitted into the backward-light side through the heat insulation fabric are effectively reduced, that is, the ultraviolet rays and the infrared rays in the sunlight are effectively blocked to achieve a good heat insulation effect. 
     Heat Insulation Curtain of the First Embodiment 
     See  FIG. 1  and  FIG. 2 , the heat insulation curtain of this embodiment includes a base cloth  2 , and the base cloth  2  is woven by a warp thread and a weft thread in a satin weave  1  shown in  FIG. 1 . The warp thread adopts a flat aluminum thread  12 , the weft thread adopts a polyester yarn  11 , and the satin weave  1  is woven by the rapier loom. In this embodiment, the flat aluminum thread  12  adopts a flat aluminized polyester continuous filament. A warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25. 
     As shown in  FIG. 1 , the satin weave  1  is a 5/3 weft-faced satin, and a flat surface of the flat aluminum thread is arranged toward a surface of the base cloth. On the base cloth  2 , the flat aluminum thread serving as the warp thread does not bend and remains in a straight line state, and the polyester yarn serving as the weft thread has less cover to the flat aluminum thread, thereby forming a warp-faced weave on one surface of the base cloth. One surface of the base cloth  2  which is the warp-faced weave is taken as a light-facing surface, that is, the majority area of the light-facing surface of the heat insulation curtain is pieced by the flat surface of the flat aluminum thread. 
     As shown in  FIG. 2 , during usage, the light-facing surface of the heat insulation curtain faces toward the sun, such that most of the ultraviolet rays and the infrared rays in the sunlight irradiated on the toward-light surface are directly reflected off, and part of the remaining ultraviolet light and infrared light are absorbed by the base cloth and are sent to an outer side of the heat insulation curtain in a radiation way. Therefore, the ultraviolet rays and the infrared rays transmitted into a room through the heat insulation curtain are effectively reduced, that is, the ultraviolet rays and the infrared rays in the sunlight are effectively blocked to achieve a good heat insulation effect. 
     Heat Insulation Curtain of the Second Embodiment 
     See  FIG. 2  and  FIG. 3 , the heat insulation curtain of this embodiment of includes a base cloth  2 , and the base cloth  2  is woven by a warp thread and a weft thread in a twill weave  3  shown in  FIG. 2 . The warp thread adopts a flat aluminum thread  32 , the weft thread adopts a polyester filament  31 , and the twill weave  3  is woven by the rapier loom. In this embodiment, the flat aluminum thread  32  adopts a flat aluminized polyester continuous filament, and the polyester filament  31  adopts a polyester continuous filament. A warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 18. 
     As shown in  FIG. 3 , the twill weave  3  is a 1/3 twill, and a flat surface of the flat aluminum thread is arranged toward the surface of the base cloth. On the base cloth  2 , the flat aluminum thread serving as the warp thread does not bend and remains in a straight line state, and the polyester yarn serving as the weft thread has less cover to the flat aluminum thread, thereby forming a warp-faced weave on one surface of the base cloth. One surface of the base cloth  2  which is the warp-faced weave is taken as a light-facing surface, that is, the majority area of the light-facing surface of the heat insulation curtain is pieced by the flat surface of the flat aluminum thread. 
     As shown in  FIG. 2 , during usage, the light-facing surface of the heat insulation curtain faces toward the sun, such that most of the ultraviolet rays and the infrared rays in the sunlight irradiated on the toward-light surface are directly reflected off, and part of the remaining ultraviolet light and infrared light are absorbed by the base cloth and are sent to the outer side of the curtain in a radiation way. Therefore, the ultraviolet rays and the infrared rays transmitted into the room through the heat insulation curtain are effectively reduced, that is, the ultraviolet rays and the infrared rays in the sunlight are effectively blocked to achieve a good heat insulation effect. 
     The main idea of this invention is to use the flat aluminum thread as the warp thread and the polyester yarn or the polyester filament as the weft thread, and the satin weave or the twill weave is adopted to weave the base cloth of the heat insulation fabric or the base cloth of the heat insulation curtain, such that the majority area of one surface of the base cloth being the warp-faced weave is pieced by the flat surface of the flat aluminum thread, so as to reflect most of the infrared rays and the ultraviolet rays in the sunlight and to well achieve the heat insulation effect. According to this idea, the warp-direction density and the weft-direction density of the base cloth can be set to other values according to actual needs, and the specific structure of the satin weave or the twill weave has various obvious changes, which are not limited to the above-mentioned embodiments.
