Fire-retardant cloth structure

Abstract

The present invention provides a fire-retardant cloth structure, which is knitted by rib structure. The cloth structure includes first and second yarn elements in a ring pattern. The first yarn element includes glass fiber yarn and auxiliary yarn, and the second yarn element includes glass fiber yarn and fire insulating yarn. With this structure, the fire-retardant cloth presents better elasticity, good hand feel and comfort as well as a fire insulating effect with improved applicability.

1 . A fire-retardant cloth structure knitted by a rib structure the cloth structure comprising:
 a first yarn element comprising glass fiber yarn and auxiliary yarn; and   a second yarn element comprising glass fiber yarn and fire retardant yarn, said first yarn element and said second yarn element being in a loop pattern.   
   
   
       2 . The cloth structure defined in  claim 1 , wherein said auxiliary yarn is comprised of: Polyester fiber/filament, Polyamide fiber/filament and wool. 
   
   
       3 . The cloth structure defined in  claim 1 , wherein said fire retardant yarn is comprised of: Modacrylic, Viscose FR, PVC FR, Meta-Aramid and Para-Aramid. 
   
   
       4 . The cloth structure defined in  claim 1 , wherein said glass fiber yarn has a weight percentage of 35-75%. 
   
   
       5 . The cloth structure defined in  claim 1 , wherein said auxiliary yarn has a weight percentage of 10-30%. 
   
   
       6 . The cloth structure defined in  claim 1 , wherein said fire retardant yarn has a weight percentage of 20-75%.
