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 FieldThis 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 ArtBy 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.
SUMMARYAn 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'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.

What'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.
This invention will be further described below in combination with embodiments and accompanying drawings.

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.
