Fabric for screen including dope dyed fiber

Abstract

Screen fabrics are provided. In an embodiment, the screen fabric includes a regular fiber and a dope dyed fiber. The dope dyed fiber is directly included in either warps or wefts or both. Alternatively, a blended or plied fiber of the regular fiber and the dope dyed fiber is included in either warps or wefts or both. Differences in the lightness, chroma and hue of the screen fabric before and after post-processing are ±2 or less, ±2 or less and ±0.1 or less, respectively.

1 . A screen fabric including a regular fiber and a dope dyed fiber wherein the dope dyed fiber is directly included in either warps or wefts or both, or a blended or plied fiber of the regular fiber and the dope dyed fiber is included in either warps or wefts or both, and wherein differences in the lightness, chroma and hue of the screen fabric before and after post-processing are ±2 or less, ±2 or less and ±0.1 or less, respectively. 
   
   
       2 . The screen fabric of  claim 1 , wherein the dope dyed fiber is a polyester fiber. 
   
   
       3 . The screen fabric of  claim 1 , wherein either the regular fiber or the dope dyed fiber or both are blended or plied with a low-melting fiber in a weight ratio of 50:50 to 80:20. 
   
   
       4 . The screen fabric of  claim 1 , wherein the weight ratio of the regular fiber to the dope dyed fiber is from 20:80 to 80:20. 
   
   
       5 . A screen fabric for blocking light from a lighting system or sunlight, including a regular fiber and a flame retardant polyester dope dyed fiber wherein the dope dyed fiber is directly included in either warps or wefts or both, or a blended or plied fiber of the regular fiber and the flame retardant polyester dope dyed fiber is included in either warps or wefts or both, and wherein differences in the lightness, chroma and hue of the screen fabric before and after post-processing are ±2 or less, ±2 or less and ±0.1 or less, respectively. 
   
   
       6 . The screen fabric of  claim 5 , wherein either the regular fiber or the flame retardant polyester dope dyed fiber or both are blended or plied with a low-melting fiber in a weight ratio of 50:50 to 80:20. 
   
   
       7 . The screen fabric of  claim 5 , wherein the weight ratio of the regular fiber to the flame retardant polyester dope dyed fiber is from 40:60 to 80:20. 
   
   
       8 . The screen fabric of  claim 1 , wherein the regular fiber is a flame retardant fiber. 
   
   
       9 . The screen fabric of  claim 2 , wherein either the regular fiber or the dope dyed fiber or both are blended or plied with a low-melting fiber in a weight ratio of 50:50 to 80:20. 
   
   
       10 . The screen fabric of  claim 2 , wherein the weight ratio of the regular fiber to the dope dyed fiber is from 20:80 to 80:20. 
   
   
       11 . The screen fabric of  claim 5 , wherein the regular fiber is a flame retardant fiber.
