Core-sheath compounded yarn and a woven/knitted fabric having excellent covering property and abrasion resistance

Abstract

The present invention provides a core-sheath compounded yarn constituted from a high tenacity and high heat-resistant fiber and other dyeable fiber and/or dope-dyed yarn where the high tenacity and high heat-resistant fiber is arranged as a core yarn while other dyeable fiber and/or dope-dyed yarn are/is arranged in a substantially untwisted state and the surroundings thereof are spirally covered by dyeable fiber and/or dope-dyed yarn. A woven/knitted fabric where the core-sheath compounded yarn is at least partially used is also provided.

1 . A core-sheath compounded yarn constituted from a high tenacity and high heat-resistant fiber and other dyeable fiber and/or dope-dyed yarn where the high tenacity and high heat-resistant fiber is arranged as a core yarn while other dyeable fiber and/or dope-dyed yarn are/is arranged in a substantially untwisted state and the surroundings thereof are spirally covered by dyeable fiber and/or dope-dyed yarn. 
     
     
         2 . The core-sheath compounded yarn according to  claim 1  where said high tenacity and high heat-resistant fiber is polybenzazole fiber and/or p-aramid fiber. 
     
     
         3 . The core-sheath compounded yarn according to  claim 1  where said dyeable fiber and/or dope-dyed yarn are/is m-aramid fiber and/or polyamide imide fiber. 
     
     
         4 . A woven/knitted fabric where the core-sheath compounded yarn according to  claim 1  is at least partially used.
