Abstract

A unidirectional sight-transmission fabric includes 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. The base cloth is woven by the warp thread and the weft thread in a plain weave. Adjacent two of the warp threads and adjacent two of the weft thread enclose a light-transmission sight-transmission hole. A unidirectional sight-transmission curtain is also disclosed.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A unidirectional sight-transmission fabric, comprising a base cloth interwoven via a warp thread and a weft thread, wherein:
 the warp thread is a flat aluminum thread, the weft yarn is a polyester yarn or a polyester filament, and the base cloth is woven by the warp thread and the weft thread in a plain weave; and   adjacent two of the warp threads and adjacent two of the weft threads enclose a light-transmission sight-transmission hole.   
     
     
         2 . The unidirectional sight-transmission fabric according to  claim 1 , wherein the flat aluminum thread is a flat aluminized polyester continuous filament. 
     
     
         3 . The unidirectional sight-transmission fabric according to  claim 2 , wherein the flat aluminum thread is a 90D flat aluminized polyester continuous filament, and the weft thread is a 40S/1 polyester yarn. 
     
     
         4 . The unidirectional sight-transmission fabric according to  claim 1 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30. 
     
     
         5 . The unidirectional sight-transmission fabric according to  claim 2 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30. 
     
     
         6 . The unidirectional sight-transmission fabric according to  claim 3 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30. 
     
     
         7 . A unidirectional sight-transmission curtain made by a fabric, and the fabric including a base cloth interwoven via a warp thread and a weft thread, wherein:
 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 plain weave; and   adjacent two of the warp threads and adjacent two of the weft threads enclose a light-transmission sight-transmission hole.   
     
     
         8 . The unidirectional sight-transmission curtain according to  claim 7 , wherein the flat aluminum thread is a flat aluminized polyester continuous filament. 
     
     
         9 . The unidirectional sight-transmission curtain according to  claim 8 , wherein the flat aluminum thread is a 90D flat aluminized polyester continuous filament, and the weft thread is a 40S/1 polyester yarn. 
     
     
         10 . The unidirectional sight-transmission curtain according to  claim 7 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30. 
     
     
         11 . The unidirectional sight-transmission curtain according to  claim 8 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30. 
     
     
         12 . The unidirectional sight-transmission curtain according to  claim 9 , wherein a warp-direction density of the base cloth is 26, and a weft-direction density of the base cloth is 25 to 30.
