Textile Materials Containing Yarns with an Intimate Blend of Aramid Fibers and Polyphenylene Sulfide Fibers

Abstract

The invention provides a woven textile having a first and second side and comprising a plurality of yarns, wherein at least a portion of the yarns comprise an intimate blend of at least about 51% by weight polyphenylene sulfide fibers, less than about 49% by weight para-aramid fibers, and, less than about 2% by weight meta-aramid fibers. The polyphenylene sulfide, para-aramid, and meta-aramid fibers are staple fibers with an average staple fiber length of between about 20 and 100 mm.

What is claimed is: 
     
         1 . A woven textile having a first and second side and comprising a plurality of yarns, wherein at least a portion of the yarns comprise an intimate blend of:
 at least about 51% by weight polyphenylene sulfide fibers;   less than about 49% by weight para-aramid fibers; and,   less than about 2% by weight meta-aramid fibers,   wherein the polyphenylene sulfide, para-aramid, and meta-aramid fibers are staple fibers and wherein the staple fibers have an average staple fiber length of between about 20 and 100 mm.   
     
     
         2 . The woven textile of  claim 1 , wherein the woven textile is a plain weave. 
     
     
         3 . The woven textile of  claim 2 , wherein the plain weave has a warp direction and a weft direction and wherein the plain weave has between 30 and 70 ends per inch in both the warp and weft directions. 
     
     
         4 . The woven textile of  claim 1 , wherein the polyphenylene sulfide fibers are dyed. 
     
     
         5 . The woven textile of  claim 1 , wherein the yarns comprise an intimate blend of between about 60 and 85% by weight polyphenylene sulfide fibers and between about 15 and 40% by weight para-aramid fibers. 
     
     
         6 . The woven textile of  claim 1 , wherein the yarns comprise less than about 1% by weight meta-aramid fibers. 
     
     
         7 . The woven textile of  claim 1 , wherein the yarns are formed by the process of ring spinning. 
     
     
         8 . The woven textile of  claim 1 , wherein at least one of the first and second sides comprises a coating. 
     
     
         9 . The woven textile of  claim 1 , wherein at least one of the first and second sides comprises a film. 
     
     
         10 . The woven textile of  claim 1 , wherein at least one of the first and second sides comprises an adhesive. 
     
     
         11 . The woven textile of  claim 1 , wherein yarns further comprise antistatic fibers. 
     
     
         12 . The woven textile of  claim 1 , wherein the woven textile has a wash shrinkage of less than about 3% tested according to the AATCC 135 5 washes cycles procedure. 
     
     
         13 . A garment comprising the textile material of  claim 1 .
