Blackout curtain that provides complete blackout

Abstract

Disclosed is a blackout curtain that does not transmit light to the interior environment, which can be used in any environment where it is desired to prevent light from entering such as home, office, hotel, photo studios, motion picture theaters. In particular, disclosed is a curtain structure that provides 100% blackout by minimizing the light transmittance rate, which protects the privacy of private life and protects against the disturbing effect of light and UV rays.

1 . A blackout curtain that is completely (100%) light-proof, the blackout curtain comprising:
 an upper layer fabric and a lower layer fabric, which are woven with knits from warp and weft yarns and form the visible sides of the curtain;   a middle layer fabric which provides light proofing and comprises an upper part and a lower part, woven as a single layer with knits by using warp yarns and two different groups of weft yarns of high filament and black color;   connection points connecting the upper layer fabric and the upper part of the middle layer fabric to each other and connecting the lower layer fabric and the lower part of the middle layer fabric to each other; and   an upper layer floating fabric structure and a lower layer floating fabric structure located opposite the connection points to prevent light leaks.   
     
     
         2 . The curtain according to  claim 1 , wherein the said high filament, black colored weft yarns are preferably 150 denier, 288 filament black micro yarns. 
     
     
         3 . The curtain according to  claim 1 , wherein the said upper layer floating fabric structure is located opposite the connection point that connects the lower layer fabric and the lower part of the middle layer fabric. 
     
     
         4 . The curtain according to  claim 1 , wherein the said lower layer floating fabric structure is located opposite the connection point that connects the upper layer fabric and the upper part of the middle layer fabric. 
     
     
         5 . A production method to obtain blackout curtains that are completely (100%) light-proof, comprising the following process steps:
 i. weaving an upper layer fabric that forms visible sides of the curtain by using knits of warp yarns and weft yarns;   ii. weaving a middle layer fabric that comprises an upper part and a lower part, by using warp yarns and two different groups of weft yarns of high filament and black color;   iii. weaving a lower layer fabric that forms the visible sides of the curtain by using knits of warp yarns and weft yarns;   iv. connecting the upper part of the middle layer fabric with the upper layer fabric with connection points in a single weft; and   v. connecting the lower part of the middle layer fabric with the lower layer fabric with connection points in a single weft, diagonally with the connection mentioned in the previous step.   
     
     
         6 . The method according to  claim 5 , wherein in the process step ii) the middle layer fabric comprising the upper part and the lower part is woven by using double-faced satin knits with warp yarns and two different groups of weft yarns of high filament and black color. 
     
     
         7 . The method according to  claim 5 , wherein in the process step ii), preferably 150 denier 288 filament black micro yarns are used as weft yarns. 
     
     
         8 . The method according to  claim 5 , wherein with diagonally connection mentioned in the process steps iv) and v), the lower layer floating fabric structure is formed opposite to the connection point that connects the upper layer fabric and the upper part of the middle layer fabric to each other and the upper layer floating fabric structure is formed opposite to the connection point that connects the lower layer fabric and the lower part of the middle layer fabric to each other.
